Mapping from SNOMED CT Procedure (descendants of 71388002) to http://id.who.int/ichi


Group 1 Mapping from SNOMED CT (all versions) to http://id.who.int/ichi (Ichi)

Source CodeRelationshipTarget CodeComment
1344997009 (Cannula or catheter procedure)(not mapped)The SNOMED concept is a device-based grouper spanning all body systems and procedure types. ICHI classifies interventions by target anatomy, action, and approach rather than by device type, so cannula/catheter procedures are distributed across many body-system-specific codes. No single ICHI code or block exists that encompasses all cannula or catheter procedures generically.
373110003 (Emergency procedure)(not mapped)ICHI classifies health interventions by specific target (body system), action, and means, and does not include a generic "emergency procedure" concept or an urgency/context qualifier axis. The SNOMED concept describes the emergency context of any procedure rather than a specific intervention, which is outside the scope of ICHI's classification framework.
371883000 (Outpatient procedure)(not mapped)ICHI classifies health interventions by their clinical action and anatomical/functional target, not by care setting (outpatient vs. inpatient). The SNOMED concept describes a care delivery context rather than a specific intervention, and ICHI has no codes representing care setting qualifiers, making a meaningful mapping impossible.
362961001 (Procedure by intent)(not mapped)"Procedure by intent" is an abstract SNOMED CT organizing concept that classifies procedures by their purpose (therapeutic, diagnostic, prophylactic, palliative). ICHI has a structurally analogous "Action" axis with sub-blocks for Diagnostic, Therapeutic, Managing, and Preventing, but these are organizational blocks without assignable ICHI codes. No single codeable ICHI entity captures this abstract concept.
128927009 (Procedure by method)(not mapped)"Procedure by method" is an abstract SNOMED CT grouper concept that classifies all procedures by their method/technique. ICHI uses a multi-axis system where the "Action" axis implicitly classifies interventions by method, but this axis is a structural block without an assignable intervention code. No single codeable ICHI entity captures this abstract organizing principle.
373111004 (Procedure in coronary care unit)(not mapped)"Procedure in coronary care unit" is defined by the care setting (coronary care unit) rather than by a specific clinical intervention, target anatomy, or action. ICHI classifies interventions by target-action-means and has no mechanism to represent procedures defined solely by their care delivery location.
127777001 (Provider-specific procedure)(not mapped)ICHI classifies health interventions by target (body system/function) and action type, not by the type of healthcare provider who performs them. The SNOMED concept is an organizational grouper that categorizes procedures by provider specialty, a dimension that has no representation in ICHI's classification framework.
84778007 (Radiation therapy simulator aided field setting)(not mapped)ICHI contains codes for radiotherapy delivery (destruction of tissue by radiotherapy at specific body sites) but has no code representing the pre-treatment simulation or field-setting step. The concept of using a radiation therapy simulator to define and verify treatment field boundaries is not represented in the ICHI classification, which lacks granularity for radiation oncology planning procedures.
373113001 (Routine procedure)(not mapped)"Routine procedure" is a high-level SNOMED qualifier concept indicating that a procedure is routine in nature, without specifying any particular intervention, body system, or action. ICHI classifies specific health interventions by target, action, and means, and has no equivalent concept for a generic qualifier denoting that an intervention is "routine" versus emergent or urgent.
387713003 (Surgical procedure)(not mapped)ICHI does not contain a generic "Surgical procedure" concept. ICHI classifies interventions by specific body system, action, and means; surgical procedures are distributed across the entire classification without a single grouper code. No block or category in ICHI corresponds to this high-level SNOMED concept.
397794006 (Anesthesia practitioner identified)(not mapped)"Anesthesia practitioner identified" is an administrative/organizational concept recording the assignment of an anesthesia provider, typically as part of a surgical safety checklist. ICHI classifies health interventions (clinical acts performed on targets) and does not contain codes for administrative steps such as practitioner identification or assignment.
186049004 (Complaints about care)(not mapped)"Complaints about care" is an administrative/quality assurance concept relating to patient dissatisfaction with healthcare services. ICHI is a classification of health interventions and does not contain codes for complaint handling, grievance procedures, or care quality feedback processes. No ICHI code provides a meaningful match.
169282000 (Diagnostic data computerization)(not mapped)"Diagnostic data computerization" refers to the administrative/clerical process of entering or digitizing diagnostic data into computer systems (health information management). ICHI is structured around clinical health interventions and does not contain a concept representing the computerization or digital entry of diagnostic data. This administrative health information management activity falls outside the scope of ICHI's classification framework.
185488002 (In-house services)(not mapped)"In-house services" describes an administrative/organizational context for service delivery (services provided within a healthcare facility rather than externally), which is not a health intervention. ICHI classifies health interventions by target, action, and means, and does not contain a concept representing the setting or organizational mode of service delivery.
307780009 (Mail administration procedure)(not mapped)ICHI classifies health interventions and does not cover administrative office procedures such as handling, sorting, or processing postal mail/correspondence. No ICHI code adequately represents this concept; the nearest residual codes are too semantically distant to constitute a meaningful mapping.
118662001 (Medicolegal procedure)(not mapped)ICHI does not contain a concept for medicolegal procedures (medical procedures performed for legal purposes). The closest candidates — PZA.AE.AA (Autopsy) and UEJ.AA.ZZ (Assessment of legal services) — are either too narrow (covering only one subtype) or conceptually different (addressing population-level legal systems rather than individual clinical medicolegal interventions).
391029008 (Mental health HRGs)(not mapped)"Mental health HRGs" (Healthcare Resource Groups) is an administrative/financial classification system for grouping mental health services for payment purposes, not a health intervention. ICHI classifies health interventions and contains no equivalent concept for administrative resource grouping frameworks, casemix categories, or payment classification systems.
308590000 (Payment for service procedure)(not mapped)ICHI classifies health interventions and does not contain codes for administrative or financial processes such as payment processing, billing, or fee collection for healthcare services. No ICHI code adequately represents this concept.
185084007 (Place of safety court order)(not mapped)"Place of safety court order" is a specific individual-level legal/administrative intervention under mental health legislation (e.g., UK Mental Health Act Section 136) involving court-ordered protective custody for psychiatric assessment. ICHI contains no codes for involuntary psychiatric detention, mental health act orders, civil commitment, or individual-level court-ordered interventions; the closest ICHI codes (UEJ block) address population-level legal system interventions rather than individual patient legal orders.
308561006 (Report procedure)(not mapped)ICHI does not contain a code for clinical reporting, medical documentation, or administrative report generation procedures. The closest residual codes (PZB.ZY.ZY, PZB.ZZ.ZZ) are generic catch-all categories that do not meaningfully represent the concept of a report procedure.
440276004 (Storage)(not mapped)ICHI does not contain a concept for the storage of biological materials, specimens, or health-related items. The closest ICHI concepts (specimen collection, procurement, preparation) address different steps in the specimen/tissue handling workflow and are not semantically equivalent to storage.
165198008 (Writing up - publishing)(not mapped)ICHI classifies health interventions and does not include codes for the professional or administrative activity of writing up and publishing clinical or research findings. The closest ICHI codes (SCG and SFK series) relate to functional writing ability in a rehabilitation context, which is semantically distinct.
241697001 (Cessation of anesthesia)(not mapped)ICHI does not contain a code for the cessation, reversal, or discontinuation of anaesthesia. The available anaesthesia codes (DC, PZA.DC.AC, PZA.DC.AF) all represent the administration/delivery of anaesthesia rather than its termination. "Cessation of anesthesia" describes a specific phase of anaesthetic management (emergence/recovery) that has no corresponding ICHI intervention.
241713008 (Cessation of sedation)(not mapped)ICHI has no concept for sedation (only anaesthesia, which is clinically distinct) and no stem code representing the cessation or discontinuation of a sedative intervention. No single ICHI code or pre-coordinated concept captures the meaning of stopping sedation.
103748008 (Cloning procedure)(not mapped)ICHI does not contain any code for cloning procedures. Extensive searching across genome interventions, embryonic structure interventions, reproductive interventions, and cell-related procedures yielded no match. Cloning is a specialized laboratory/research technique outside the scope of ICHI's classification of clinical health interventions.
104464008 (Acid phosphatase measurement, forensic examination)(not mapped)ICHI contains no acid phosphatase test code (only alkaline phosphatase, which is a different enzyme) and has no forensic examination context. The 119 entries under "Essential laboratory tests" were exhaustively reviewed and none correspond to acid phosphatase measurement in a forensic setting.
1052227004 (Separation of conjoined twins)(not mapped)ICHI does not contain a code for the separation of conjoined twins or any sufficiently analogous multi-system surgical separation procedure. This is a rare, complex procedure involving shared organs, vasculature, and multiple body systems simultaneously that falls outside ICHI's granularity.
10724008 (Microsurgery)(not mapped)Microsurgery is defined by the use of an operating microscope rather than by a specific clinical action or anatomical target. ICHI does not classify interventions by equipment or instrumentation at the stem code level, so there is no assignable intervention code for microsurgery as a general technique.
110468005 (Ambulatory surgery)(not mapped)"Ambulatory surgery" describes a care delivery setting or mode (surgery without overnight admission), not a specific health intervention. ICHI classifies health interventions by target, action, and means, and contains no codes for care settings, service delivery modes, or categories of surgery defined by admission status.
112692001 (First stage of staged operation)(not mapped)ICHI classifies interventions by target, action, and means, not by surgical staging or sequencing. The concept of a first stage in a multi-stage surgical plan has no representation in ICHI's classification framework.
117614009 (Laboratory procedure, review by pathologist)(not mapped)ICHI does not model professional interpretation or sign-off activities within laboratory workflows. Pathologist review of laboratory results is a clinical interpretation activity that falls outside ICHI's scope, which focuses on specimen collection, testing, and treatment rather than result interpretation.
118635009 (Revision)(not mapped)SNOMED "Revision" (294 children across all body systems) represents repeating a prior procedure to correct or improve results. ICHI handles revision exclusively through the extension code XG3J07, a post-coordination qualifier applied to specific intervention codes. No standalone revision intervention code exists; the generic concept cannot be mapped to a single ICHI stem code.
1230233005 (Connection of irrigation solution container to irrigation tube)(not mapped)ICHI does not contain codes for equipment setup or assembly steps. ICHI classifies irrigation as site-specific therapeutic interventions and has no code for the preparatory act of assembling irrigation equipment. This granular nursing task falls outside ICHI's classification scope.
446717008 (Laser photocoagulation of hemorrhage)(not mapped)ICHI does not contain a generic, body-site-unspecified code for laser photocoagulation of hemorrhage. All ICHI haemostasis codes are site-specific, and none specify laser photocoagulation as the modality.
73994005 (Emergency operation)(not mapped)ICHI classifies interventions by target, action, and means, not by urgency or scheduling context. The concept of an emergency operation has no representation in ICHI's classification framework, which does not distinguish between emergency and elective procedures.
439350008 (Position equipment near subject)(not mapped)ICHI does not contain a code for the logistical/preparatory activity of positioning equipment near a patient. The closest candidates address different concepts (installation/management of assistive products) rather than the physical act of placing general medical equipment in proximity to a subject. This SNOMED concept falls outside ICHI's classification scope.
88094004 (Cryopreservation)(not mapped)ICHI does not contain a code for cryopreservation or any equivalent concept covering the freezing and long-term storage of biological material (tissues, cells, organs, gametes). The closest ICHI codes involve therapeutic cooling of living patients (PZA.SE.ZZ) or specimen collection (PZX.AH.XH), neither of which captures the semantics of cryopreservation as a laboratory preservation technique.
16488004 (Laboratory reporting)(not mapped)"Laboratory reporting" refers to the administrative and communicative process of compiling and disseminating laboratory test results. ICHI does not contain a code for this activity; it covers specific laboratory tests and specimen collection but not the reporting/communication of results as a distinct health intervention.
59615004 (Laboratory test order by laboratory initiative)(not mapped)ICHI does not model ordering workflows, requisition processes, or the administrative context of who initiates a laboratory test. This concept describes a workflow qualifier rather than a health intervention, placing it outside ICHI's classification scope.
26895000 (Laboratory test order cancelation)(not mapped)ICHI classifies health interventions (clinical procedures, diagnostics, treatments), not administrative workflow actions such as order cancellation. The closest code, XG9S58 "Discontinuing," is a generic extension code for stopping an intervention already in progress, which is semantically distinct from cancelling an order for a test that was never performed.
35631009 (Laser surgery)(not mapped)SNOMED CT "Laser surgery" is a generic, body-site-unspecified concept defined solely by the surgical modality (laser). ICHI does not have any site-unspecified laser surgery code; its architecture requires every intervention to specify a target anatomy combined with an action and approach. The only ICHI codes mentioning "laser" are organ-specific (brain, liver), which are far too narrow.
168525009 (Postoperative course of radiotherapy)(not mapped)ICHI models radiotherapy only as site-specific "Destruction of lesion or tissue of [body site] by radiotherapy" codes. There is no site-unspecified or generic radiotherapy code, and no concept for adjuvant/postoperative radiotherapy as a treatment course. PZA.GA.BA (Total body irradiation) is a clinically distinct procedure.
726549007 (Radioimmunoguided surgery)(not mapped)Radioimmunoguided surgery (RIGS) is a specialized surgical technique using radiolabeled monoclonal antibodies with intraoperative gamma probe detection to guide tumor resection. ICHI has no code representing this technique; it lacks both a nuclear medicine/radionuclide guidance extension code and any category for intraoperative radionuclide-guided surgery.
401271004 (Email sent to patient)(not mapped)ICHI has no code specifically representing a healthcare provider sending an electronic written message (email) to a patient. The closest codes (SFK series) relate to supporting a patient's own message-writing ability rather than a provider sending a communication. This administrative communication act falls outside the scope of ICHI's health intervention classification.
397819007 (Application of surgical drapes)(not mapped)ICHI does not include a code for the application of surgical drapes. This is a perioperative ancillary procedure related to sterile field preparation that falls outside ICHI's classification scope. The closest candidates ("DK - Application of dressing", "LZZ.DK.AH") refer to wound dressings rather than sterile surgical drapes, making them semantically distinct.
21268002 (Cytopathology procedure, forensic)(not mapped)ICHI has no assignable intervention code combining cytopathology with forensic/medicolegal context. Forensic qualifiers are not represented in ICHI's stem code structure, and cytopathology examination exists only as extension code XG4JJ6, which cannot serve as a standalone mapping target.
708255002 (First line treatment)(not mapped)"First line treatment" is a treatment sequencing/priority qualifier in SNOMED CT, not a specific health intervention. ICHI classifies concrete interventions by body system, target, and action type, and has no concept for the ordering or priority of treatment lines. No ICHI code provides a meaningful semantic match.
180862005 (Temporary operation)(not mapped)ICHI classifies interventions by what is done (target, action, means), not by duration or permanence. The concept of a temporary/interim surgical procedure has no representation in ICHI's classification framework.
183488000 (Non-urgent surgical admission)(not mapped)ICHI classifies health interventions (clinical and therapeutic actions), not administrative events such as hospital admissions. "Non-urgent surgical admission" is an administrative/logistical concept describing the planned admission of a patient for elective surgery, and has no corresponding code in ICHI.
183489008 (Non-urgent psychiatric admission)(not mapped)ICHI classifies health interventions (clinical procedures, assessments, therapies) and does not contain concepts for hospital admissions or hospitalization processes. "Non-urgent psychiatric admission" is an administrative/service delivery event that falls outside the scope of ICHI.
362964009 (Palliative procedure)(not mapped)ICHI classifies interventions by target, action, and means, not by clinical intent (curative, palliative, prophylactic). Palliative intent has no representation in ICHI's stem code structure, so no assignable intervention code captures this concept.
708256001 (Second line treatment)(not mapped)"Second line treatment" is an abstract qualifier describing treatment sequencing (therapy given after first-line failure), not a specific health intervention. ICHI classifies concrete interventions by target, action, and means, and contains no codes representing the concept of treatment line ordering or therapy escalation.
708257005 (Third line treatment)(not mapped)"Third line treatment" is a treatment sequencing qualifier indicating the third step in a therapeutic escalation pathway. ICHI does not contain any concept representing treatment line ordering; it classifies health interventions by what is done, to what, and by what means, and the concept falls outside ICHI's classification framework.
183492007 (Non-urgent pediatric admission)(not mapped)ICHI classifies health interventions (procedures, assessments, therapies) and does not contain codes for hospital admission events. "Non-urgent pediatric admission" is an administrative/encounter concept describing the act of admitting a child to hospital on a scheduled basis, which falls outside the scope of the ICHI classification entirely.
183493002 (Non-urgent gynecological admission)(not mapped)ICHI classifies health interventions (procedures), not administrative events such as hospital admissions. "Non-urgent gynecological admission" describes a non-emergency administrative admission to a gynecological specialty, which has no counterpart in ICHI.
183494008 (Non-urgent obstetric admission)(not mapped)ICHI classifies health interventions and does not contain codes for administrative encounter types such as hospital admissions or their urgency qualifiers. "Non-urgent obstetric admission" is an administrative/encounter concept with no reasonable ICHI counterpart.
183495009 (Non-urgent orthopedic admission)(not mapped)"Non-urgent orthopedic admission" describes an administrative encounter type (elective hospital admission for orthopedic care), not a health intervention. ICHI classifies health interventions and has no codes for hospital admission events, urgency/priority classification, or encounter types.
183496005 (Non-urgent ENT admission)(not mapped)"Non-urgent ENT admission" is an administrative/encounter concept describing a scheduled hospital admission to an ear, nose, and throat specialty service. ICHI classifies health interventions and procedures, not hospital admissions by urgency level and clinical specialty.
183497001 (Non-urgent trauma admission)(not mapped)ICHI classifies health interventions and does not contain concepts for hospital admission events, urgency classifications, or encounter-level administrative acts. "Non-urgent trauma admission" is an administrative/encounter concept with no counterpart in ICHI.
183498006 (Non-urgent ophthalmological admission)(not mapped)ICHI classifies health interventions (clinical and procedural acts), not administrative events such as hospital admissions. "Non-urgent ophthalmological admission" is an administrative/logistical concept with no corresponding intervention code in ICHI.
183499003 (Non-urgent rheumatology admission)(not mapped)ICHI classifies health interventions (clinical procedures, assessments, and actions on body systems), not administrative processes such as hospital admissions. "Non-urgent rheumatology admission" describes an elective inpatient admission to a specific medical specialty, a concept with no counterpart in ICHI.
183500007 (Non-urgent dermatology admission)(not mapped)ICHI classifies health interventions (clinical and functional actions), not administrative care events such as hospital admissions. There is no ICHI code that represents admitting a patient to a dermatology or any other specialty inpatient service on a non-urgent basis.
183501006 (Non-urgent neurology admission)(not mapped)ICHI does not have codes for specialty-specific hospital admissions or urgency-qualified encounter types. "Non-urgent neurology admission" is an administrative encounter concept that falls outside the scope of ICHI's intervention-based classification.
183502004 (Non-urgent urology admission)(not mapped)ICHI classifies health interventions (procedures and actions), not administrative hospital admission events. There is no ICHI code that represents specialty-specific hospital admissions or urgency-qualified admissions.
183503009 (Non-urgent radiotherapy admission)(not mapped)ICHI does not classify administrative admission events. "Non-urgent radiotherapy admission" is an administrative act of scheduling/admitting a patient for radiotherapy, which has no direct counterpart in ICHI.
183504003 (Non-urgent hematology admission)(not mapped)ICHI does not have codes for hospital admissions or specialty-ward-specific administrative events. "Non-urgent hematology admission" describes an elective inpatient admission to a hematology specialty, a concept outside ICHI's scope as a classification of health interventions.
183505002 (Non-urgent plastic surgery admission)(not mapped)"Non-urgent plastic surgery admission" describes an administrative act of scheduling or admitting a patient for elective plastic surgery. ICHI classifies health interventions rather than administrative processes like hospital admissions or urgency-based triage categories.
183506001 (Non-urgent diabetic admission)(not mapped)ICHI does not classify admission types or disease-specific encounter categories. "Non-urgent diabetic admission" is an administrative/encounter concept describing planned hospital admission for diabetes management, which falls outside the scope of ICHI.
183507005 (Non-urgent respiratory admission)(not mapped)ICHI classifies health interventions and does not contain codes for hospital admissions, admission urgency categories, or specialty-specific encounter types. "Non-urgent respiratory admission" is an administrative healthcare process concept with no reasonable counterpart in ICHI.
183508000 (Non-urgent psychogeriatric admission)(not mapped)ICHI has no specific code for hospital admissions or psychogeriatric services. "Non-urgent psychogeriatric admission" is an administrative concept describing a planned inpatient admission to a geriatric psychiatry service, which falls outside ICHI's scope of health interventions.
183509008 (Non-urgent renal medicine admission)(not mapped)ICHI does not classify hospital admissions or urgency categories as health interventions. "Non-urgent renal medicine admission" is an administrative encounter concept describing a scheduled admission to a nephrology specialty, with no counterpart in ICHI.
183510003 (Non-urgent neurosurgical admission)(not mapped)ICHI classifies health interventions (procedures, therapies, diagnostics) and does not contain concepts for hospital admission events or their urgency levels. "Non-urgent neurosurgical admission" is an administrative/organizational action that falls outside ICHI's scope.
183511004 (Non-urgent cardiothoracic admission)(not mapped)ICHI classifies health interventions, not administrative events such as hospital admissions. The concept of a non-urgent cardiothoracic admission — describing urgency level and specialty ward placement — has no reasonable counterpart in ICHI.
183512006 (Non-urgent oral surgical admission)(not mapped)"Non-urgent oral surgical admission" is an administrative event describing elective hospital admission for oral surgery. ICHI classifies health interventions (clinical procedures, assessments, management actions), not hospital admission events, and no ICHI code captures this concept.
702596005 (Fertility preservation procedure)(not mapped)ICHI lacks a code for fertility preservation as a unified concept. While individual component procedures exist (e.g., NMA.JH.AC transvaginal oocyte retrieval, NGD.AH.XE specimen collection of sperm), none capture the concept of preserving reproductive material through cryopreservation for future fertility use.
241028002 (Clamping of drain)(not mapped)ICHI has no code for clamping or occluding a surgical drain. The only clamping code (NMM.LA.AH) is specific to umbilical cord clamping. All occlusion (LA) codes apply to anatomical structures, not medical devices. The management of internal device (SN) codes are all site-specific with no generic residual code and describe general device management rather than the specific action of clamping.
274075007 (Optional surgery)(not mapped)"Optional surgery" is an administrative/contextual qualifier describing the elective nature of a surgical intervention, not a specific health intervention. ICHI classifies interventions by target, action, and means, and has no codes representing the urgency or elective status of a procedure.
303163003 (Treatments administered under the provisions of the law)(not mapped)The SNOMED concept describes clinical treatments delivered to individual patients under legal authority. ICHI has no code for this; the closest candidates address population-level policy enforcement, not individual clinical treatments under legal mandate. The semantic gap is too large for mapping.
405255005 (Euthanasia)(not mapped)ICHI does not contain any code for euthanasia, medically assisted dying, or any related concept. Euthanasia is not classified as a standard health intervention in the WHO ICHI framework, and no meaningful semantic mapping exists.
447183004 (Surgical procedure using stereotactic ultrasound guidance)(not mapped)ICHI handles imaging guidance through extension codes rather than assignable intervention codes. The stereotactic technique has no representation in ICHI at all. No standalone intervention code exists for image-guided or stereotactic surgery as a general concept.
44749005 (Subsequent stage of staged operation)(not mapped)ICHI classifies interventions by target, action, and means, not by surgical staging or sequencing. The concept of a subsequent stage in a multi-stage surgical plan has no representation in ICHI's classification framework.
711364006 (Robotic assisted surgery)(not mapped)ICHI handles robotic assistance through the extension code XG5Z48, a post-coordination qualifier applied to specific surgical intervention codes. No standalone intervention code exists for robotic-assisted surgery as a general concept.
737301002 (Prophylactic surgical procedure)(not mapped)ICHI classifies interventions by target, action, and means, not by clinical intent. Prophylactic/preventive intent in a surgical context has no representation in ICHI's stem code structure; prophylactic surgeries are coded by the specific procedure performed without an intent modifier.
816079005 (Vascularized composite allotransplantation)(not mapped)ICHI does not contain codes for vascularized composite allotransplantation (face, hand, uterus transplants). The available transplantation codes are limited to specific solid organs (heart, lung, liver, kidney, pancreas, intestine, spleen) and do not include multi-tissue composite grafts.
432021006 (Administration of substance via intracavernous route)(not mapped)ICHI contains no code for injection or administration of a substance into the corpus cavernosum of the penis; the "Interventions on penis" block (BlockL5-NGM) includes surgical, imaging, and prosthetic codes but no drug/substance injection code, and no other section of the classification captures this route of administration. The closest code (NGM.LI.AE, Corpus cavernosum shunt) refers to a shunt procedure for priapism and is semantically unrelated to pharmacological intracavernous injection.
119265000 (Assisting)(not mapped)"Assisting" in SNOMED is a highly generic method/action concept that applies across all types of health interventions, but ICHI has no corresponding general-purpose "assistance" category — every ICHI code is a specific combination of target, action, and means. The closest ICHI category found, SPD "Assisting others," is scoped to a narrow domestic life/participation rehabilitation domain and does not represent the broad procedural sense of the SNOMED concept.
1287774005 (Attention to anastomosis)(not mapped)ICHI contains numerous codes for surgically creating anastomoses (action axis LB) across multiple anatomical targets, but has no code representing post-procedural attention, monitoring, or care directed at an existing anastomotic site. The concept of "attending to" a previously formed anastomosis — encompassing assessment, inspection, and management — falls outside ICHI's coded scope.
410025003 (Clamping)(not mapped)ICHI has no generic "clamping" code representing the abstract surgical act of applying a clamp — it only has body-site-specific occlusion codes (e.g., NMM.LA.AH Umbilical cord clamping) or vascular occlusion categories, none of which capture "Clamping" as a body-site-neutral, general procedural concept. The SNOMED concept is a high-level abstraction that does not map reasonably to any specific ICHI category.
59690005 (Compensating filter design and fabrication)(not mapped)ICHI does not contain any code representing radiotherapy treatment planning, dosimetry, beam modification, or the design and fabrication of custom radiation beam-modifying devices; its radiotherapy coverage is limited to the actual delivery of radiation to specific body sites. No ICHI category comes close enough to this specialised radiotherapy physics activity to constitute even an approximate match.
10012005 (Expression)(not mapped)ICHI has no generic, site-unspecified code for manual expression of fluid or tissue contents; it organizes all interventions by a specific target body part, and the concept of external manual compression/expression (as in breast milk expression, Crede maneuver, or cyst content expression) does not exist as a standalone category at any level of the ICHI hierarchy. The SNOMED concept is an abstract, site-agnostic procedure type that falls outside ICHI's assignable code space.
372042004 (Counting procedure-related devices)(not mapped)ICHI does not contain any concept for the perioperative safety activity of counting surgical instruments, sponges, needles, or devices before wound closure — this granular patient-safety/administrative act has no corresponding category or block in the ICHI classification. All synonym searches (instrument count, sponge count, surgical safety check, device count, surgical count, swab count) and hierarchy browsing of perioperative, health management, and health services sections returned no applicable code.
424128006 (Decompression)(not mapped)The SNOMED concept "Decompression" is a high-level, site-unspecified abstract category covering all decompression procedures across any body region. ICHI has no generic decompression category code — the only ICHI codes containing "decompression" in their title are site-specific (orbit only: BAM.FC.AA, BAM.FC.AD), and these are far narrower than the SNOMED concept; no ICHI block or category meaningfully represents unspecified decompression as a whole.
363066000 (Destructive procedure by anatomic site)(not mapped)"Destructive procedure by anatomic site" is a high-level SNOMED grouping concept covering all destruction procedures across every body site; ICHI encodes destruction via the action axis `GA` distributed across hundreds of site-specific assignable categories (e.g., AAA.GA.AA, KMA.GA.AA) but provides no single code or block that represents destruction generically across all anatomic sites. No ICHI category or block serves as a reasonable cross-cutting equivalent for this abstract grouper.
30700006 (Excision of transplanted tissue or organ)(not mapped)ICHI does not have a cross-organ category for excision of a previously transplanted tissue or organ; transplant-related excision codes exist only at the individual organ level (e.g., nephrectomy, hepatectomy) without any qualifier distinguishing transplanted from native tissue, and no overarching aggregation code exists for this SNOMED concept. The SNOMED concept is a high-level parent abstraction that has no structural or semantic equivalent in the ICHI classification.
169332007 (External beam radiation therapy with internal radiotherapy)(not mapped)ICHI encodes radiotherapy by anatomical target (e.g., NGA.GA.BA for prostate, LCA.GA.BA for breast) rather than by treatment modality or modality combination, so there is no code representing combined external beam and internal (brachytherapy) radiation therapy as a site-independent concept. The only non-site-specific radiotherapy code, PZA.GA.BA (Total body irradiation), refers to a distinct procedure (conditioning for bone marrow transplant) and is not a reasonable match.
394902000 (High dose brachytherapy)(not mapped)ICHI does not contain a standalone brachytherapy or dose-rate-specific radiotherapy code; all ICHI radiotherapy entries are site-specific (e.g., "Destruction of lesion or tissue of [organ] by radiotherapy") and none represent brachytherapy as a modality independent of target anatomy. The SNOMED concept describes a technique-level intervention (HDR brachytherapy) that has no equivalent representation in ICHI's classification structure.
1335864002 (Imaging guided radiotherapy using fiducial marker target localization)(not mapped)ICHI encodes radiotherapy only at the level of specific body-site targets (e.g., destruction of prostate by radiotherapy) and does not have a technique-level or modality-qualifier code for image-guided radiotherapy or fiducial-marker-based target localisation as a standalone intervention; no assignable ICHI category code reasonably represents this concept.
414525000 (Interposition procedure)(not mapped)The term "interposition" does not appear anywhere in ICHI's terminology across all search strategies (direct text, fuzzy, synonyms including transposition, repositioning, graft, reconstruction). SNOMED CT concept 414525000 is itself a high-level grouper under "Procedure by method" that encompasses a heterogeneous family of techniques (interposition arthroplasty, bowel interposition, nerve interposition, etc.) — ICHI encodes these as distinct body-part-specific categories with no single overarching "interposition procedure" concept, making any mapping misleading.
384692006 (Intracavitary brachytherapy)(not mapped)ICHI does not contain a technique-level or modality-level code for intracavitary brachytherapy as a standalone concept; radiotherapy interventions in ICHI are organised by anatomical target site (e.g., NME.GA.BA for uterus, NMF.GA.BA for cervix), so the site-agnostic SNOMED concept "Intracavitary brachytherapy" has no single corresponding ICHI code. Assigning any single site-specific ICHI radiotherapy code would be narrower and misleading given that the SNOMED concept covers the technique applied across multiple body cavities.
107733003 (Introduction procedure)(not mapped)"Introduction procedure" is a high-level SNOMED grouper encompassing all procedures that introduce something (substance, device, material) into the body — a category spanning ICHI action axes DB (Application of substance), DL (Insertion of internal device), and many others across dozens of body-system-specific codes. ICHI has no single assignable grouper code at this level of abstraction, making any mapping misleading; the concept is best left unmatched rather than mapped to a code that would misrepresent its breadth.
1156707000 (Low dose rate brachytherapy)(not mapped)ICHI has no generic brachytherapy code independent of anatomical target — every assignable ICHI code requires a target axis, and "brachytherapy" as a modality-level concept (let alone LDR specifically) does not exist as a standalone code. "Brachytherapy seeds" and "Interstitial radioactive material" appear only as extension codes without a primary 3-axis code, and site-specific destruction-by-radiotherapy codes (e.g., NGA.GA.BA for prostate) are too narrow in scope to represent a general modality concept.
228714000 (Making of beam direction shell for radiotherapy)(not mapped)ICHI contains no code for fabricating or constructing a patient-specific radiotherapy immobilisation device (beam direction shell/mask); all radiotherapy codes represent the treatment itself, and immobilisation device codes represent application or fitting of the device rather than its manufacture. This preparatory technical fabrication act falls outside ICHI's coded scope.
228718002 (Making of docking unit for radiotherapy)(not mapped)ICHI does not contain any codes for the fabrication or construction of radiotherapy positioning/fixation devices (docking units), and the scope of radiotherapy-related codes in ICHI covers only the irradiation procedures themselves (e.g., total body irradiation, destruction by radiotherapy) rather than preparatory device-making activities. No sufficiently related ICHI category could be identified across searches for radiotherapy, docking, fabrication, positioning device, fixation, applicator, mould, or related terms.
228721000 (Making of surface mold for brachytherapy)(not mapped)ICHI contains no code representing the fabrication or construction of a brachytherapy surface mold or applicator; all brachytherapy and radiotherapy codes in ICHI model the therapeutic delivery action itself (e.g., destruction by radiotherapy) rather than preparatory device manufacturing. This highly specific technical/preparatory step lies outside ICHI's modelled scope.
10110004 (Platelet adhesiveness test)(not mapped)ICHI contains no code for platelet adhesiveness or platelet function testing; the only platelet-related laboratory code is XG9YD3 (Platelet count), which is a quantitative cell count and does not represent the functional adhesiveness assay performed in this SNOMED concept. No code in the Essential laboratory tests block or elsewhere in ICHI covers specialised platelet function or adhesion assessment.
103714007 (Occlusion of catheter)(not mapped)ICHI has no generic code for managing or clearing a blocked/occluded catheter regardless of catheter type; device management codes are all organ-system-specific (e.g., urinary bladder, vascular, biliary) and none captures this concept at the body-system-agnostic level that the SNOMED term represents. The closest candidates (NAI.SN.AC, IZE.SN.AF) are too anatomically constrained and would misrepresent the scope of the SNOMED concept.
50917001 (Preparation of radioactive source)(not mapped)ICHI does not contain a clinical procedure code for the preparation of a radioactive source; all radiation-related ICHI codes either describe the therapeutic delivery of radiation to a specific anatomical target (e.g., radiotherapy destruction codes) or are public health/environmental interventions under the UBR block, none of which cover the physics/pharmacy preparatory act of readying a radioactive source. The "Brachytherapy seeds" and "Interstitial radioactive material" entries found are ICHI extension codes specifying the means/material used in a procedure, not standalone procedure codes for source preparation.
85921004 (Puncture procedure)(not mapped)ICHI has no generic/abstract puncture code — all puncture-related codes (e.g., AAG.AH.AE Cranial puncture, ABG.AH.AE Lumbar puncture, JAE.JB.AE Puncture of paranasal sinus) are bound to a specific anatomical target by ICHI's triaxial structure (Target.Action.Means), making it structurally impossible to represent a body-site-agnostic "Puncture procedure" as a single assignable ICHI code.
169357002 (Radiotherapy by infiltration of tissue)(not mapped)ICHI has no site-independent code for interstitial brachytherapy/radiotherapy by tissue infiltration as a technique; all ICHI radiotherapy codes (pattern *.GA.BA) require a specific body target (e.g., prostate, breast, brain), whereas this SNOMED concept represents a delivery method category applicable across body sites. No single ICHI assignable category code captures the cross-cutting "interstitial radiotherapy" concept.
700356003 (Radium 226 brachytherapy)(not mapped)ICHI does not have a standalone, body-site-agnostic brachytherapy code — all radiotherapy destruction codes (action GA, means BA) are site-specific (e.g., prostate, cervix, breast), and "Brachytherapy seeds" and "Interstitial radioactive material" appear in ICHI only as extension/means-axis qualifiers without an assignable alphanumeric code. Because the SNOMED concept specifies a modality (Radium-226 brachytherapy) without a body site, no valid ICHI category code can be assigned.
422395007 (Removal of arterial catheter)(not mapped)ICHI does not contain a code for removal of an arterial catheter; the arterial intervention blocks (upper limb, lower limb, thoracic, abdominal arteries) contain no device removal categories, and no generic arterial catheter removal code exists anywhere in the classification.
301883009 (Removal of arterial cross clamp)(not mapped)An arterial cross clamp is a temporary intraoperative occlusion maneuver, not an implanted device, and its removal (declamping) is an integral step of the surgical procedure rather than a separately classifiable intervention; ICHI has no code for this act.
231021005 (Removal of epidural electrode)(not mapped)ICHI has no specific code for removal of an epidural electrode; an epidural electrode sits in the epidural space — not the spinal canal itself — and no code specifically addresses this anatomical target combined with electrode removal. The closest candidate (ABG.JD.AA) is too anatomically imprecise to assign with confidence.
225716004 (Reposition endotracheal tube)(not mapped)ICHI covers insertion (JBA.DL.AC), suctioning (JBA.JB.AC), and removal (JBA.JD.AC) of endotracheal tube, but does not have a code for the action of repositioning or adjusting the position of an in-situ endotracheal tube; no LD (repositioning) action is assigned to the trachea target.
230588002 (Reposition of cardiac pacemaker pocket)(not mapped)The ICHI pacemaker block (HFC) includes insertion, implantation, removal, replacement, and management/function-check codes, but contains no code for surgical revision or repositioning of the subcutaneous generator pocket itself; the concept is too specific to be captured by any available ICHI category.
428626000 (Securing endotracheal tube using tape)(not mapped)ICHI contains codes for insertion, suctioning, and removal of endotracheal tubes but no code for the post-insertion nursing procedure of securing or fixating the tube with tape; this highly specific procedural step has no reasonable ICHI equivalent.
778013008 (Securing of catheter)(not mapped)ICHI contains numerous catheter insertion and management codes but no code captures the specific procedural act of securing or fixating a catheter in place; this nursing/technical step is below ICHI's level of granularity.
395074007 (Selectron therapy)(not mapped)Selectron therapy is a proprietary low-dose-rate intracavitary brachytherapy technique using caesium-137; ICHI has no brachytherapy-specific category codes, and no radiotherapy code captures intracavitary brachytherapy as distinct from external beam radiotherapy.
115979005 (Stabilization)(not mapped)ICHI does not have a generic "Stabilization" category; all ICHI stabilisation codes are specific to named musculoskeletal joints, and the SNOMED concept represents a high-level, non-specific procedure type with no valid parent-level ICHI equivalent.
439865001 (Taking an impression for creation of custom definitive obturator prosthesis)(not mapped)ICHI contains no code for impression-taking or pre-fabrication measurement of the palate/obturator site; the hard and soft palate blocks cover only surgical interventions, and no prosthesis planning or mould-making code exists for this target.
439761003 (Taking an impression for creation of custom interim obturator prosthesis)(not mapped)ICHI has no code for palate impression-taking or obturator prosthesis pre-fabrication measurement; the distinction between interim and definitive obturator is irrelevant since the entire concept class is absent from ICHI.
439762005 (Taking an impression for creation of custom nasal prosthesis)(not mapped)The nose interventions block contains no measurement or impression-taking code; all nasal codes are surgical or functional, and no prosthesis planning or mould-making code exists for this target.
439262009 (Taking an impression for creation of custom orbital prosthesis)(not mapped)The orbital block contains no measurement or pre-fabrication code; BZZ.SM.AH (Management of ocular prosthetics) covers ongoing prosthesis management, not the pre-fabrication impression step, and is too semantically distant.
439263004 (Taking an impression for creation of custom palatal lift prosthesis)(not mapped)ICHI has no code representing the taking of a dental/prosthodontic impression; the palate blocks contain only surgical interventions, with no category for a pre-fabrication measurement or mould-taking procedure.
439975002 (Taking an impression for creation of custom surgical obturator prosthesis)(not mapped)As with the palatal lift impression, ICHI contains no category for impression-taking as a preparatory step for prosthesis fabrication; "obturator" hits in ICHI refer only to anatomical structures, and no prosthodontic workflow code exists.
1287433006 (Therapeutic diathermy)(not mapped)ICHI does not contain a code for diathermy as a modality — searches for diathermy, electrocautery, electrocoagulation, electrotherapy, radiofrequency, and cauterization all returned no results. ICHI encodes destruction and ablation procedures by body target rather than by energy modality.
89002000 (Therapeutic ultrasound)(not mapped)Extensive searching across modality terms (ultrasound therapy, acoustic, phonophoresis, sonotherapy, physical therapy, physiotherapy) found no ICHI code representing therapeutic ultrasound as a standalone modality. ICHI does not classify physical agent modalities as generic categories independent of body target.
363327001 (Thermography by site)(not mapped)ICHI contains no thermography or infrared imaging codes — this modality (thermal/infrared imaging of body sites) is absent from the ICHI classification entirely. No reasonable proxy exists that captures the concept without significant semantic distortion.
428419009 (Thrombolysis of access catheter)(not mapped)This SNOMED concept refers to pharmacological dissolution of a clot occluding an indwelling vascular access catheter — a maintenance/device-care procedure distinct from thrombolysis of a blood vessel. ICHI's thrombolysis codes all target specific named blood vessels, and no code exists for thrombolysis directed at a catheter device itself.
5182000 (Total body perfusion)(not mapped)ICHI has isolated limb perfusion codes and cardiopulmonary bypass but no code representing perfusion of the entire body; the SNOMED concept describes a distinct procedure (whole-body vascular perfusion) for which no adequate ICHI category exists.
66391000 (Traction)(not mapped)ICHI only contains anatomically specific traction codes (spinal traction, skull tongs/halo device insertion) and has no generic cross-anatomical traction concept that would correspond to the high-level SNOMED grouper concept "Traction."
16656451000119100 (Transcatheter biopsy)(not mapped)ICHI has no generic transcatheter biopsy code spanning all organs; all catheter-based biopsy entries in ICHI are organ-specific (e.g., transjugular liver biopsy, percutaneous transluminal biopsy of myocardium), and none can represent this technique-level SNOMED concept.
439244000 (Transcatheter insertion of radiation delivery device for intravascular coronary brachytherapy)(not mapped)ICHI has no code for intravascular coronary brachytherapy or insertion of a radiation delivery device into a coronary artery; the coronary artery block contains angioplasty, stenting, bypass, thrombolysis, and repair codes but nothing for endovascular radiation delivery.
81188004 (Transcatheter therapy)(not mapped)ICHI does not have a single generic "transcatheter therapy" code; the term "transcatheter" in ICHI appears only as the means axis qualifier within specific procedure codes, and there is no superordinate block or category that would map to this broad SNOMED concept.
228696008 (Yttrium 90 brachytherapy)(not mapped)ICHI contains no site-neutral brachytherapy or radioisotope therapy code; the one "Brachytherapy seeds" category found had no usable code identifier, and all radiotherapy-destruction codes in ICHI are organ-specific, making it impossible to map a non-site-specified Y-90 brachytherapy concept without introducing incorrect site specificity.
702590004 (Ablation using fluoroscopic guidance)(not mapped)This SNOMED concept specifies only a guidance modality (fluoroscopy) without a target organ or body site; ICHI codes always require a complete Target + Action + Means triple, and no ICHI code encodes fluoroscopic guidance as a standalone or generic ablation procedure independent of a specific anatomical target.
430270007 (Ablation using ultrasound guidance)(not mapped)Like ablation under fluoroscopic guidance, this SNOMED concept specifies only an imaging guidance modality without a body target; ICHI has no code for generic ultrasound-guided ablation and requires a fully specified Target + Action + Means combination, so no reasonable ICHI mapping exists.
89562006 (Abrasion of epicardial surface)(not mapped)The epicardial surface (visceral pericardium) block in ICHI (BlockL5-HFF) contains pericardiectomy, pericardiotomy, adhesion release, and repair codes, but no code for mechanical abrasion of the epicardial or pericardial surface exists; the mechanistically nearest code (HFF.FC.AA, release of adhesions of pericardium) does not capture abrasion as an intervention intent.
370882000 (Abuse prevention)(not mapped)ICHI does not have a single "prevention" action code in the violence domain; prevention as a goal spans multiple ICHI actions (education, awareness raising, capacity building, policy), and no single ICHI code meaningfully represents the SNOMED concept of abuse prevention as an intervention type.
386505006 (Acid-base management: respiratory alkalosis)(not mapped)ICHI has no codes covering acid-base balance management or its subtypes (respiratory alkalosis, metabolic alkalosis, etc.); the closest structural area — water, mineral and electrolyte balance functions (BlockL5-ETE) — concerns electrolyte/mineral homeostasis, not acid-base regulation, and contains only assessment and education codes with no management or therapeutic action equivalent.
386502009 (Acid-base regulation: metabolic acidosis)(not mapped)As with respiratory alkalosis, ICHI contains no codes for acid-base regulation or metabolic acidosis management; no synonym search (pH, bicarbonate, blood gas, metabolic management) yielded a relevant ICHI category, and the general metabolic functions block (BlockL5-ETB) covers metabolic rate assessment and education only, not acid-base therapeutic interventions.
413063005 (Acinetobacter species screening test)(not mapped)ICHI does not index organism-specific microbiological screening tests; searches for Acinetobacter, bacterial screening, microbiology, pathogen, culture, specimen collection, and infection control all failed to produce a code scoped to diagnostic screening for a specific bacterial genus, and the infection control codes in ICHI address environmental and population-level control measures rather than diagnostic laboratory screening tests.
302171008 (Adjust hearing aid settings)(not mapped)ICHI contains no assignable code for adjusting or programming an external hearing aid; CCB.SM.AH covers management of cochlear implant prosthetics (a surgically implanted device), and the hearing aid entries found in the search are supply/assistive-product catalogue entries, not clinical intervention codes.
410617001 (Adjustment)(not mapped)"Adjustment" as a bare SNOMED concept is a high-level abstract procedure category with no body site, action, or clinical context specified; ICHI requires a defined target-action-means combination, so no single ICHI code can represent this non-specific concept. The only ICHI codes named "adjustment" (KBF.SN.AA/AB) are specific to gastric band device adjustment and are not appropriate for a generic mapping.
438810005 (Adjustment of arm sling)(not mapped)ICHI contains codes for application of external immobilisation devices (e.g., MEB.LC.AH for humerus) and for replacement/re-application (KB action), but no code specifically covers adjustment or readjustment of a sling as a minor external supportive device; PZX.LC.AH (application of cast or splint, NEC) and other immobilisation codes were considered but describe initial application rather than adjustment of an already-applied sling.
239700001 (Adjustment of cast brace)(not mapped)ICHI codes for external immobilisation devices cover application (LC) and replacement (KB) of casts and splints, but there is no code representing adjustment or modification of an already-applied cast brace; the concept of in-situ adjustment without removal and reapplication is not represented.
239661009 (Adjustment to attachment point of traction system)(not mapped)A thorough search across "traction," "attachment," "positioning," "immobilisation," and related terms found no ICHI code representing adjustment of a traction system or its attachment points; ICHI does not appear to classify the management of skeletal or skin traction apparatus at this level of granularity.
239660005 (Adjustment to weight applied by traction system)(not mapped)ICHI contains no codes representing the adjustment of traction weight or the calibration of a traction system; the closest traction code (MBZ.LC.AE) encodes the initial application of skeletal traction to the spine, which is semantically distinct from modifying the weight parameters of an already-applied traction device.
1371349009 (Administration of antihistamine)(not mapped)ICHI does not classify interventions by drug class; no codes for antihistamine, anti-allergic, or histamine-receptor-blocking agent administration exist, and the only medication-related generic code (UAC.RD.ZZ, "Providing medications") is so broad as to be semantically uninformative and not a reasonable mapping target.
710170000 (Administration of prophylactic treatment)(not mapped)ICHI does not have a general "prophylactic treatment" category — it classifies interventions by specific target and action rather than by preventive intent. No ICHI code captures the broad, route- and substance-agnostic concept of prophylaxis administration without collapsing into an overly unrelated code.
440252007 (Administration of radiopharmaceutical)(not mapped)ICHI does not contain a dedicated code for radiopharmaceutical administration as a class; radiotherapy-related codes in ICHI describe destruction by radiotherapy or radioisotope scanning by organ, not the act of administering a radiopharmaceutical agent generically across targets and purposes.
1285465008 (Administration via specific route)(not mapped)This is a high-level SNOMED grouper concept for any route-based administration; ICHI has no equivalent abstract code and organises route-specific administration only at the level of individual organ targets combined with specific means, making a single mapping impossible.
313331005 (Admission for social reasons)(not mapped)No ICHI code adequately represents admission to a health facility motivated by social rather than clinical reasons; ICHI social-support codes (e.g., UEO.RG.ZZ) address population-level service provision rather than the individual act of admission, and the distinction of social motivation for admission is not captured anywhere in the ICHI hierarchy.
427675001 (Admission from establishment)(not mapped)ICHI does not classify administrative acts such as patient admission or transfer between facilities; this concept describes a logistical/administrative event rather than a health intervention. No ICHI code captures the act of receiving or discharging a patient from an establishment.
305335007 (Admission to establishment)(not mapped)Like "Admission from establishment," this concept describes an administrative/organisational act (the act of admitting a patient to a care facility) that falls entirely outside ICHI's scope of classifiable health interventions; no ICHI code addresses patient admission as such.
370879005 (Adult day center education)(not mapped)ICHI education codes (PM action axis) are all tied to a specific body function, health behaviour, or system (e.g. "Education about sleep functions", "Education about screening behaviours"), whereas "Adult day center education" refers to a setting-specific general educational programme with no defined clinical topic; no single ICHI code captures this concept without gross distortion.
385784004 (Advanced practice nursing care)(not mapped)ICHI does not classify interventions by the professional cadre delivering them (e.g., advanced practice nurse vs physician); the classification is organised by what is done to whom, not who does it. No code or block captures this administrative/role-based concept, making a meaningful match impossible.
704077003 (Allograft of amniotic membrane)(not mapped)ICHI does not contain a code for amniotic membrane grafting in any context (ophthalmologic, wound care, or obstetric); the only amniotic structure codes (NMM.JB.*) relate to drainage of the amniotic sac, and no graft, transplantation, or reconstruction code targeting amniotic membrane tissue exists.
88884005 (Alpha-1-antitrypsin phenotyping)(not mapped)ICHI's Essential Laboratory Tests block does not include alpha-1-antitrypsin testing or any general protein phenotyping/isoelectric-focusing procedure; no other ICHI section covers biochemical or genetic phenotyping at this level of specificity.
278743005 (Amputation incision)(not mapped)"Amputation incision" refers to the initial skin/tissue incision step within an amputation procedure, rather than the complete amputation; ICHI codes represent complete interventions, not individual surgical steps, so no appropriate ICHI code exists for this granular operative detail.
444153003 (Analysis using conformation sensitive capillary electrophoresis)(not mapped)ICHI does not contain any codes for electrophoresis techniques, including capillary electrophoresis variants; the classification does not cover specific laboratory analytical methods used in molecular diagnostics.
444270004 (Analysis using denaturing gradient gel electrophoresis)(not mapped)Denaturing gradient gel electrophoresis (DGGE) is a highly specific molecular biology technique with no representation in ICHI; the classification does not classify the analytical methodology used within laboratory assays at this level of specificity.
444267003 (Analysis using denaturing HPLC)(not mapped)High-performance liquid chromatography (HPLC) and its variants are not represented in ICHI; the classification's scope does not extend to specific analytical separation techniques used in laboratory diagnostics.
444268008 (Analysis using digital PCR)(not mapped)Digital PCR is a specific molecular quantification technique not present in ICHI; searches for PCR, polymerase chain reaction, amplification, and nucleic acid analysis return only a few infectious disease-specific assay codes with no general PCR methodology category.
444269000 (Analysis using gene copy number technique)(not mapped)Gene copy number analysis (e.g., array CGH, qPCR-based CNV detection) has no representation in ICHI; the classification does not classify cytogenomic or molecular copy number assay methodologies.
444283003 (Analysis using loss of heterozygosity technique)(not mapped)ICHI does not contain any codes for molecular genetics techniques such as loss of heterozygosity (LOH) analysis; the laboratory section covers only basic/essential clinical tests and lacks representation of allele-specific molecular analysis methods.
443843009 (Analysis using meta-PCR)(not mapped)ICHI has no codes for PCR-based laboratory techniques in general, and meta-PCR (a consensus/broad-range PCR approach) is not represented anywhere in the classification; the closest available code is narrowly scoped to viral testing.
444284009 (Analysis using multiplex ligation dependent probe amplification)(not mapped)Multiplex ligation-dependent probe amplification (MLPA) is a specialised molecular technique for copy-number and gene dosage analysis; ICHI contains no codes for probe-based amplification methods or molecular genetics analyses of this type.
444091001 (Analysis using multiplex PCR - polymerase chain reaction)(not mapped)ICHI does not include codes for PCR-based molecular diagnostics beyond narrow disease-specific viral nucleic acid tests; multiplex PCR as a technique category has no representation in the classification.
444092008 (Analysis using mutagenically separated PCR)(not mapped)Mutagenically separated PCR (MS-PCR) is a highly specific allele-discrimination technique with no equivalent or related code in ICHI; the classification does not model molecular laboratory methodologies at this level of specificity.
444093003 (Analysis using oligonucleotide ligation assay)(not mapped)ICHI contains no codes for molecular genotyping techniques such as oligonucleotide ligation assay; the genome block covers only genetic counselling, and the essential laboratory tests section does not include specialized mutation-detection methods.
444285005 (Analysis using PCR polyacrylamide gel electrophoresis)(not mapped)Neither PCR nor gel electrophoresis terminology appears anywhere in ICHI; the classification does not represent molecular laboratory techniques at this level of specificity.
444286006 (Analysis using protein truncation test)(not mapped)The protein truncation test is a specialized in-vitro transcription/translation assay for detecting truncating mutations; no equivalent or parent code for protein analysis methods of this kind exists in ICHI.
444287002 (Analysis using pyrosequencing)(not mapped)Pyrosequencing is a DNA sequencing-by-synthesis technique; ICHI has no codes for any next-generation or targeted sequencing methods, and no sufficiently broad laboratory analysis code exists to serve as a reasonable approximation.
444075004 (Analysis using quantitative fluorescent PCR)(not mapped)Quantitative fluorescent PCR (QF-PCR) is used for rapid aneuploidy detection; ICHI's viral nucleic acid amplification tests are disease-specific diagnostic tests rather than generic PCR-based analysis methods, and none cover chromosomal/genetic QF-PCR applications.
444151001 (Analysis using single strand conformation polymorphism technique)(not mapped)Single strand conformation polymorphism (SSCP) is a highly specialised molecular genetics technique used for mutation detection; no ICHI code corresponds to this method or its functional equivalent, and available genome-related codes (e.g., genetic counselling) are entirely unrelated procedurally.
266726004 (Anatomo-physiological assistance)(not mapped)"Anatomo-physiological assistance" is a legacy SNOMED concept referring to support that compensates for anatomical or physiological deficits; ICHI has no single code capturing this broad category, and no available code in the rehabilitation, support, or body function sections is close enough to recommend even as a relatedto match without significant distortion.
122502001 (Anchoring)(not mapped)ICHI contains no procedure code for "anchoring" as a standalone intervention; the SNOMED concept describes a procedural technique (e.g., orthodontic or surgical anchoring) that lacks a corresponding ICHI category, and broader "fixation" codes are all organ/site-specific rather than representing the generic anchoring technique.
398228004 (Anesthesia consultation)(not mapped)ICHI contains no code for a pre-anesthesia consultation or any generic clinical consultation activity; ICHI's anaesthesia codes represent the administration of anaesthesia itself, not a consultative encounter to evaluate or plan it.
386515000 (Animal-assisted therapy)(not mapped)ICHI contains no assignable category for animal-assisted therapy; the Creative therapy extension block holds only music and art therapy and is not suitable for this concept.
702731000 (Answering patient preoperative questions)(not mapped)ICHI has no codes for preoperative patient communication or surgical briefing; advising/education codes in ICHI are tied to specific body function/activity targets and none cover this perioperative information exchange.
1303710009 (Antenatal prevention of fetal injury of brain)(not mapped)ICHI contains no code for preventive interventions directed at the fetal brain; the NMR block covers procedural interventions on fetal structures but none address prophylaxis or neuroprotection.
386516004 (Anticipatory guidance)(not mapped)Anticipatory guidance is preventive counselling about expected developmental stages and upcoming health risks; ICHI has body-system-specific advising codes but no general preventive guidance category.
897713009 (Antineoplastic chemoimmunotherapy)(not mapped)ICHI does not contain terminology for chemotherapy, immunotherapy, or antineoplastic regimens — these pharmacological administration concepts fall outside ICHI's coded procedure set.
410619003 (Application)(not mapped)"Application" as a standalone SNOMED concept is an abstract top-level category with no specific clinical content; ICHI has no single code representing the generic concept of application in isolation.
312037009 (Application for charitable grant)(not mapped)ICHI does not contain codes for administrative applications for charitable or philanthropic grants; this falls outside its scope of health interventions.
362987001 (Application for funding)(not mapped)"Application for funding" is a generic administrative act with no ICHI counterpart; ICHI does not represent individual-level funding applications or financial advocacy at this level of specificity.
179211003 (Application of extension traction)(not mapped)ICHI's only traction code is specific to the spine (MBZ.LC.AE), and no general limb extension traction code exists; no sufficiently related match available.
713147009 (Application of hemostatic agent)(not mapped)ICHI contains no generic "application of haemostatic agent" code — haemostasis codes are organ-specific and none cover topography-unspecified application of a haemostatic substance.
370775006 (Application of safety device)(not mapped)ICHI does not contain a concept for generic application of a safety device to a patient; the category is too broad and cross-cutting to map to any single ICHI intervention code without losing essential clinical meaning.
183432009 (Application to foster a child)(not mapped)"Application to foster a child" is an administrative/legal social care act (formally applying to become a foster carer) that falls entirely outside ICHI's scope of health interventions; no ICHI code represents this legal or social welfare process.
301761003 (Arthroscopic synovial biopsy)(not mapped)ICHI has arthroscopic biopsy codes for specific named joints (e.g., knee, hip, shoulder) but no general-purpose arthroscopic synovial biopsy code spanning unspecified joints; the SNOMED concept does not specify which joint, and synovium is not a named target axis in ICHI, so no adequate mapping exists.
178887009 (Articulated prosthetic replacement of bone)(not mapped)ICHI has no general code for prosthetic replacement of bone across unspecified sites; all analogous codes (joint implantation, reconstruction) are site-specific, and no target-axis-neutral "bone prosthetic replacement" category exists in the classification.
82305005 (Artificial graft)(not mapped)ICHI encodes grafts only as site-specific procedures (e.g., skin graft to trunk, bone graft to lumbar spine) and has no general, site-nonspecific "artificial graft" category; this SNOMED concept functions as a broad qualifier rather than a discrete procedure assignable to a single ICHI code.
239221000 (Aspiration and injection of ganglion cyst)(not mapped)ICHI has no code for ganglion cyst as a target structure, and no combined aspiration-plus-injection code at an unspecified anatomical site; the closest candidates (percutaneous drainage of wrist or ankle joint) are both anatomically incorrect (ganglion cysts are periarticular soft tissue, not intra-articular) and omit the injection component entirely.
710838003 (Assessment of barriers to adherence)(not mapped)ICHI contains no code or block for barriers to adherence or treatment compliance; the terms "adherence," "compliance," and "barriers" return no results in the classification. While UAC.AA.ZZ (assessment of medications) is tangentially related, it does not capture the concept of evaluating obstacles to adherence and would be too distorted a mapping.
1300108002 (Assessment of barriers to communication)(not mapped)ICHI has a communication interventions block and includes an "Assessment of communication, unspecified" entry, but this code is flagged as `_LDINCOMPLETE` (no finalized code assigned), making it non-assignable. The concept of assessing barriers specifically — rather than assessing communication ability itself — also has no equivalent in ICHI.
709506004 (Assessment of readiness for disclosure of health status)(not mapped)No ICHI code addresses readiness to disclose health information — ICHI does not model the communicative or psychosocial readiness aspects of health status disclosure, and no related code in the activities/participation, mental functions, or health behaviour domains comes close enough to justify a mapping.
18321000202107 (Assessment of triggering factor)(not mapped)Extensive searching across assessment codes, risk factor, aetiology, precipitating, and causal terminology returned no ICHI code that corresponds to assessing triggering or precipitating factors of a condition; this is a generic clinical reasoning activity not represented as a distinct ICHI intervention.
1343660007 (Assistance with search for childcare)(not mapped)ICHI has no specific code for assisting a person in finding or searching for childcare services. Related blocks (education and training services UEQ, parent-child relationships SSK, parenting behaviours VEJ) do not capture the act of helping someone locate and obtain childcare arrangements.
710802005 (Assisting health care provider)(not mapped)ICHI has no code representing a health worker assisting another health care provider during a clinical procedure; the classification focuses on interventions delivered to patients or populations, not on inter-professional support roles within a procedure team.
223455001 (Assisting with procedure)(not mapped)ICHI classifies health interventions by their clinical target, action, and means — it does not include a generic concept for a clinician or nurse assisting another provider during an unspecified procedure; this SNOMED concept represents a nursing/support role rather than a classifiable health intervention in the ICHI framework.
307776004 (At risk registration)(not mapped)"At risk registration" is an administrative/social care act of placing an individual (typically a child or vulnerable person) on a formal protection register; ICHI does not contain any intervention concept covering registry enrolment, at-risk designation, or child protection administrative procedures.
57961007 (Attachment of pedicle graft to extremity)(not mapped)ICHI contains a "Pedicle flap" extension code (XG9JE8) and limb-specific skin graft codes (LAE.ML.AA, LAG.ML.AA), but none of these combine the pedicle-flap technique specifically applied to an extremity as a single assignable category. The extension code is not independently assignable, and no category captures the full concept of attaching a pedicled graft to a limb.
184988003 (Attend court for solicitor)(not mapped)This SNOMED concept describes a clinician attending court on behalf of a legal matter, which is an administrative/legal activity rather than a health intervention. ICHI's legal services block addresses population-level legal system interventions rather than individual professional court attendance, so no appropriate code exists.
276843008 (Attention to implanted drug delivery system)(not mapped)ICHI has no code specifically covering management, checking, or reprogramming of an implanted drug delivery/infusion pump system. While a code for "Implantable insulin infusion pump" appears as a residual/unnamed entry, no assignable category exists for attending to such devices, and the concept spans multiple possible body targets, making a single defensible mapping impossible.
401300000 (Atypical pneumonia screening test)(not mapped)ICHI contains no codes for serological or microbiological diagnostic tests targeting atypical pneumonia pathogens (e.g. Mycoplasma, Chlamydophila, Legionella); the classification does not cover laboratory diagnostic testing at this level of specificity.
117043000 (Automated laboratory procedure)(not mapped)ICHI contains no category for automated or general laboratory procedures — the only laboratory-related content is a block for essential laboratory tests (BlockL1-XG1) and one specific serology test, neither of which represents the concept of an automated laboratory procedure as a procedural category. No reasonable ICHI code captures this administrative/technological descriptor.
315205008 (Bank holiday home visit)(not mapped)This SNOMED concept describes an administrative scheduling context — a GP home visit occurring on a public/bank holiday — rather than a clinical intervention. ICHI classifies health interventions by clinical content and has no mechanism for encoding scheduling or timing qualifiers such as bank holiday status.
430715008 (Bariatric operative procedure)(not mapped)This SNOMED concept is a high-level grouper category for all weight-loss surgical procedures (gastric bypass, sleeve gastrectomy, gastric banding, etc.), not a specific intervention. ICHI contains individual bariatric procedure codes (e.g. KBF.LI.AA Gastric bypass, KBF.LL.AA Gastroplasty) but no single umbrella code broad enough to represent the full extent of this SNOMED grouper, making a meaningful single-code mapping impossible.
386521001 (Bedside laboratory testing)(not mapped)ICHI does not contain a code representing point-of-care or bedside laboratory testing as a distinct intervention category; specimen-collection codes exist (e.g. DIA.AH.XA) and the separate ICD-11 extension block "Essential laboratory tests" (BlockL1-XG1) covers analyte-specific tests, but none captures the delivery-setting concept of laboratory testing performed at the patient's bedside.
386526006 (Bibliotherapy)(not mapped)ICHI has no code for bibliotherapy (therapeutic use of reading/literature); the Creative therapy extension block contains Art therapy (XG0NM7) and Music therapy (XG2BX7) but not bibliotherapy, and there is no suitable psychotherapy or counselling code that captures this specific intervention modality.
68689009 (Bifurcation)(not mapped)ICHI contains no procedure code for bifurcation as a surgical act (creating or modifying a vessel/structure bifurcation); the only ICHI entity containing "bifurcated" is XA5EY2 (Bifurcated ligament), which is an anatomical extension code rather than a procedure code.
28150003 (Biofeedback procedure)(not mapped)No ICHI code or block specifically represents biofeedback as a technique — ICHI does not encode the use of physiological signal feedback as a therapeutic modality. Searches across training, behavioural therapy, relaxation, physiological regulation, and related terms returned no usable match.
86273004 (Biopsy)(not mapped)ICHI does not have a generic "Biopsy" category independent of a target body part — every biopsy code in ICHI requires a specific anatomical target (e.g., brain, myocardium, fetal structures). The SNOMED concept "Biopsy" is a pure procedure category with no body-site specified, and no ICHI code or block exists at that level of abstraction.
406163006 (Bioterrorism preparedness)(not mapped)ICHI has no code for bioterrorism preparedness specifically; searches across related domains (disaster, terrorism, biological threat, security, capacity building for health services) returned nothing semantically close. The concept is a governmental/public health planning activity that falls outside ICHI's coded scope.
53721003 (Bolus design and fabrication)(not mapped)A radiation therapy bolus is a custom tissue-equivalent compensator fabricated for external beam radiotherapy treatment; ICHI has no code for this design-and-fabrication activity, and the radiotherapy codes present (e.g. destruction by radiotherapy) cover treatment delivery, not device manufacturing. No reasonable ICHI match exists.
19671003 (Bone thermography)(not mapped)Thermography (infrared thermal imaging) is not represented in ICHI — the classification has no thermal/infrared means axis code, and the bone imaging section (BlockL6-MRB) only contains X-ray, CT, MRI, and nuclear scintigraphy, none of which correspond to thermography.
440609002 (Brachytherapy monitoring)(not mapped)ICHI has no monitoring code specific to brachytherapy or radiation therapy in progress; the general monitoring action (AI axis) exists for specific physiological targets but not for treatment-course surveillance of brachytherapy, and the brachytherapy seeds concept in ICHI is an extension/supply code rather than a procedure. No reasonable single ICHI assignable code covers clinical monitoring during a course of brachytherapy treatment.
236961005 (Breast stimulation)(not mapped)This SNOMED concept refers to nipple/breast stimulation used to provoke uterine contractions (e.g., nipple stimulation stress test in obstetrics). ICHI contains no code for this procedure; the only breast stimulation-adjacent code (LCA.SC.AH, phototherapy to breast) refers to light therapy for mastitis and is semantically unrelated.
789249004 (Butyrylcholinesterase screening test)(not mapped)Butyrylcholinesterase (pseudocholinesterase) activity measurement is a specific serum enzyme assay not represented in the ICHI essential laboratory test block or elsewhere in the classification; no category or block in ICHI corresponds to this test or to general enzyme activity screening at a level of specificity that would constitute a reasonable match.
117337005 (Calculated laboratory test method)(not mapped)ICHI's Essential Laboratory Tests block contains specific named tests (creatinine, albumin, platelet count, etc.) but has no concept for a generic "calculated" laboratory method or methodology type. The SNOMED concept describes an abstract method category (calculation-based lab testing), not a specific procedure, and no ICHI code represents this procedural methodology class.
313385005 (Cardiology emergency hospital admission)(not mapped)ICHI does not classify hospital admissions or triage events as health interventions; this SNOMED concept describes an administrative/access-to-care event (emergency admission in a cardiology setting) for which there is no corresponding ICHI category or block.
83613005 (Cardiopericardiopexy)(not mapped)Cardiopericardiopexy is a historical procedure that surgically creates adhesions between the pericardium and adjacent structures (such as omentum or chest wall) to induce collateral myocardial blood supply. ICHI has no fixation or adhesion-creation code for the pericardium — the pericardium block (HFF) covers only biopsy, injection, incision, adhesion release, excision, and repair.
66605009 (Cardiopneumopexy)(not mapped)Cardiopneumopexy is another historical revascularization procedure in which the lung is sutured to the epicardium to promote adhesion and collateral blood supply to the myocardium. ICHI contains no code representing intentional creation of cardiopulmonary adhesions, and no relevant pexy operation exists for the heart or lung targeting this concept.
183477006 (Cardiothoracic emergency hospital admission)(not mapped)This SNOMED concept describes an administrative care pathway event (emergency hospital admission for a cardiothoracic condition), not a clinical or public health intervention performed on a patient. ICHI does not classify hospital admission as an intervention type, so no reasonable ICHI code exists for this concept.
107841008 (Cardiovascular system destructive procedure)(not mapped)ICHI has no code representing destructive procedures on the cardiovascular system as a general category; destructive interventions exist only for narrow, specific cardiovascular targets (e.g., vein of thorax, cardiac conduction system) and no unspecified or grouper-level cardiovascular destruction code is available.
119763006 (Cardiovascular system transposition procedure)(not mapped)ICHI contains only a handful of transposition codes (cranial nerve, peripheral nerve, extraocular muscle, parotid structures) and none applicable to cardiovascular structures. Cardiovascular transpositions such as arterial switch operations appear in ICHI under reconstruction or repair codes (e.g. HBD.LI.AA), which are semantically distinct actions, so no reasonable ICHI transposition code maps to this SNOMED grouper.
391264006 (Care for mentally disordered offenders HRGs)(not mapped)This is an NHS England Healthcare Resource Group (HRG) administrative classification concept denoting a funding/tariff grouping for forensic mental health services, not a clinical intervention. ICHI contains no forensic, offender, or HRG-administrative codes, and no ICHI concept reasonably represents this administrative care category.
225355000 (Care of patient states)(not mapped)"Care of patient states" is a high-level SNOMED grouper concept covering the general domain of maintaining patient condition and wellbeing; no single ICHI category or block meaningfully captures this broad, heterogeneous concept, and mapping to an umbrella ICHI block would not add useful semantic information.
24218006 (Care of patient's personal effects)(not mapped)This SNOMED concept describes a nursing/administrative activity of safeguarding or managing a patient's belongings (valuables, possessions), which is a custodial act with no corresponding target or action in ICHI. The closest ICHI concept (SP2.RA.ZZ — caring for household objects) sits in the domestic-life participation domain and concerns the patient's own ability to manage household objects, not a clinician managing a patient's personal effects.
281173007 (Casting of dental model)(not mapped)Casting of a dental model is a dental laboratory/auxiliary step (pouring gypsum/stone into an impression to produce a study or working model) that does not constitute a direct health intervention on a patient in ICHI's scope; no corresponding assignable ICHI category exists for this procedure.
27411008 (Cauterization)(not mapped)"Cauterization" is a technique/means (a type of tissue destruction using heat or chemical agents) rather than a complete health intervention — ICHI requires a Target + Action + Means structure, so a standalone technique concept without a specified body site or target has no direct ICHI equivalent. No ICHI code represents cauterization as an abstract method independent of anatomical target.
128424005 (Cauterization with laser)(not mapped)ICHI does not have a generic "cauterization with laser" or "laser cauterization" category that applies across body sites; laser therapy in ICHI is only coded at the site-specific level (e.g., laser interstitial thermal therapy of brain or liver), and no body-site-independent laser destruction code exists. The SNOMED concept is a technique modifier rather than a complete procedure, and there is no corresponding unspecified/NEC laser cauterization code in ICHI.
168445004 (Cell chromosome examination)(not mapped)ICHI contains no codes for cytogenetic or karyotype analysis — laboratory diagnostic procedures such as chromosome examination are outside the classification's scope, which focuses on health interventions rather than standalone laboratory tests.
86088003 (Centesis)(not mapped)ICHI encodes specific centesis procedures (pericardiocentesis, pleurocentesis, culdocentesis, amniocentesis) at the site-specific level but has no generic "centesis" or "aspiration of body fluid, unspecified" category that would map to this high-level SNOMED concept. Assigning any single site-specific code would be narrower and misleading.
386233007 (Cerebral perfusion promotion)(not mapped)"Cerebral perfusion promotion" is a nursing care bundle intervention (NIC concept) aimed at optimising cerebral blood flow through positioning, fluid management, and related actions; ICHI has no equivalent multi-component nursing management code targeting cerebral perfusion, and no single ICHI procedure code adequately represents this concept.
642006 (Cerebral thermography)(not mapped)ICHI has no thermography code at all — the modality (infrared thermal imaging) is absent from the classification. The closest brain imaging codes are conventional modalities (CT, MRI, ultrasound, PET, encephalography), none of which represent thermography.
178046009 (Certification of admission)(not mapped)Certification of admission is an administrative/legal act (typically for involuntary psychiatric detention) and ICHI contains no codes for medico-legal documentation, certification, or formal admission procedures.
312243002 (Cesium 137 brachytherapy remote afterloading)(not mapped)ICHI has no assignable code for brachytherapy remote afterloading; "Brachytherapy seeds" appears only as an extension/means modifier without a standalone code, and no ICHI category captures the specific technique of remote afterloading with a radioactive isotope (Cs-137).
397963004 (Cessation of anesthesia by withdrawal of anesthetic agent)(not mapped)ICHI encodes the administration of anaesthesia (PZA.DC.AC inhalational, PZA.DC.AF intravenous) but has no code representing the discontinuation or reversal/withdrawal of an anaesthetic agent; the XG2 extension block for "initiating/maintaining/discontinuing" is a modifier rather than a standalone assignable code.
45213002 (Chain of custody procedure)(not mapped)ICHI does not include a code for chain of custody procedures, which are administrative/legal documentation processes; the classification covers clinical, rehabilitative, and public health interventions, and no block or category addresses forensic evidentiary handling.
79453001 (Chain of custody procedure in laboratory specimen handling)(not mapped)As with the parent concept, ICHI has no code for chain of custody in laboratory specimen handling; while ICHI includes specimen collection codes, it does not encode the administrative chain-of-custody documentation step that governs evidentiary or legal integrity of specimens.
228578006 (Chaining technique)(not mapped)"Chaining technique" is a specific behavioural/occupational therapy approach (forward or backward chaining of task steps) used to teach sequenced activities; ICHI classifies interventions by target, action, and means but has no concept representing this specific instructional methodology.
6035001 (Chart abstracting)(not mapped)Chart abstracting is a health information management task involving extraction and summarisation of clinical data from patient records for administrative, billing, or research purposes. ICHI does not classify medical records administration or health information management activities at this level of specificity.
42965003 (Chart completion by medical records)(not mapped)Chart completion by medical records staff is a health information management activity focused on ensuring clinical documentation is complete and accurate. ICHI has no codes representing medical records administration, documentation management, or related health information management processes.
29064005 (Chart opening)(not mapped)Chart opening refers to the administrative act of creating or initiating a new patient medical record, which is a health information management process. ICHI does not classify patient registration or medical record initiation activities, and no available ICHI code reasonably covers this administrative procedure.
54455007 (Chart review, verification of charges)(not mapped)This SNOMED concept describes a clinical billing and compliance activity — reviewing the medical record to verify that documented charges are accurate and supported. ICHI contains no codes for charge verification, billing review, or related health administrative/financial activities.
225717008 (Check endotracheal tube is secure)(not mapped)ICHI contains codes for insertion (JBA.DL.AC), suctioning (JBA.JB.AC), and removal (JBA.JD.AC) of the endotracheal tube, but has no code representing the clinical act of checking or verifying that a tube is correctly positioned and secured. This is a nursing assessment activity with no ICHI equivalent.
225253009 (Checking cervix covered by cap)(not mapped)ICHI has no code for checking or verifying the placement of a cervical cap as a contraceptive barrier device. The cervix block (NMF) covers surgical interventions only, and no contraceptive device placement or verification code exists in the classification.
439326006 (Checking of special footwear)(not mapped)ICHI contains codes for installation (PND.DP.AH) and removal of assistive products to the foot, as well as a general "Therapeutic footwear" entity, but no code representing the act of checking, inspecting, or assessing special footwear. The concept describes a monitoring/verification activity that falls outside ICHI's assignable procedure scope.
55284006 (Chemical method)(not mapped)"Chemical method" is a SNOMED qualifier/method concept rather than a concrete health intervention, and ICHI classifies interventions by target–action–means triples rather than abstract procedural modifiers; no ICHI code corresponds to this generic concept.
117637003 (Chemical OR drug identification procedure)(not mapped)This SNOMED concept represents an abstract category grouping any procedure that identifies a chemical or drug substance; ICHI contains no matching laboratory identification concept at this level of generality, and the XG-series laboratory codes that exist are highly specific tests with no umbrella chemical/drug identification code.
9336009 (Chemical test, qualitative and quantitative)(not mapped)This is a broad SNOMED grouper for chemical laboratory testing covering both qualitative and quantitative methods; ICHI's laboratory section contains only specific named tests and has no general "chemical test" category that would represent this abstract procedural concept.
88708002 (Chemical test, quantitative)(not mapped)ICHI does not classify chemical laboratory tests by quantitation method (quantitative vs. semi-quantitative); its Essential Laboratory Tests extension block contains only specific named analyte tests and panels, with no code representing a generic quantitative chemical test category.
113066000 (Chemical test, semi-quantitative)(not mapped)As with the quantitative variant, ICHI has no code corresponding to a semi-quantitative chemical test as a method class; the classification is analyte-specific rather than organised by measurement precision, leaving no reasonable match.
271405000 (Chemical/poison screening)(not mapped)ICHI contains no toxicology, poison, or drug-screening codes; exhaustive searches on toxicology, poison, drug screening, substance, and related synonyms returned no relevant results, confirming this clinical activity has no representation in the ICHI classification.
703985001 (Chest thrust)(not mapped)Chest thrust is a specific manual airway-clearance maneuver (used in infant choking relief) that does not map to any ICHI code. The nearest candidates — cardiopulmonary resuscitation and airway insertion codes — all represent fundamentally different interventions with no adequate coverage of this targeted compressive maneuver.
237485003 (Chiasmopexy)(not mapped)Chiasmopexy (surgical fixation of the optic chiasm) has no corresponding ICHI code. The optic chiasm appears only as an extension/anatomy code with no associated intervention categories, and the brain/cranial nerve block contains no fixation or traction-relief procedures applicable to the chiasm.
103798009 (Chromogenic substrate assay)(not mapped)A chromogenic substrate assay is a specific laboratory analytic technique (measuring enzyme activity via colour-generating substrates, used in coagulation and other testing) for which ICHI has no corresponding code; the essential laboratory tests block contains no coagulation-method-specific assay codes.
108261007 (Chromosome analysis, cytogenetic procedure AND/OR molecular biology method)(not mapped)Exhaustive searches for "chromosome", "cytogenetic", "karyotype", "karyotyping", "genomic", "molecular biology", "DNA", and "nucleic acid" returned no ICHI codes covering chromosome analysis as a clinical laboratory procedure. ICHI does not appear to have an assignable category representing cytogenetic or chromosomal analysis of a patient specimen.
308430004 (Chronic disease recall)(not mapped)Searches for "recall", "follow-up", "chronic disease", "disease management", "health check", and browsing the health services policy blocks found no ICHI category representing a system-initiated recall or re-contact of a patient with a chronic disease for review. This administrative care-coordination activity has no assignable ICHI equivalent.
40148000 (Clamping of thoracic drain)(not mapped)ICHI has codes for thoracic/pleural drainage and pleural drainage device replacement, but no code specifically representing the clamping or temporary occlusion of an existing thoracic drain tube; this nursing/clinical management action is not represented in ICHI.
225139000 (Cleaning skin creases)(not mapped)ICHI contains no code for cleaning or washing skin creases; the skin intervention block covers surgical and clinical procedures but not basic hygiene/cleaning of skin folds, and the "hygiene behaviours" block addresses population-level public health interventions rather than direct clinical patient care.
18699002 (Clinical laboratory specimen identification)(not mapped)ICHI covers specimen collection extensively but does not represent post-collection laboratory processes such as specimen identification, labelling, or tracking; this administrative/pre-analytical laboratory workflow concept has no corresponding ICHI category.
62087002 (Clinical laboratory specimen rejection)(not mapped)Specimen rejection is a quality-management/administrative laboratory process that falls entirely outside ICHI's scope; ICHI codes interventions performed on patients or populations, not analytical or administrative laboratory workflow decisions.
110465008 (Clinical trial)(not mapped)ICHI classifies health interventions applied to individuals or populations, not research study designs; no code exists for "clinical trial" as an organizational or methodological construct, and the concept falls entirely outside ICHI's scope.
112695004 (Closure)(not mapped)"Closure" is a non-specific, high-level SNOMED procedural concept that spans an enormous range of anatomical sites and techniques; ICHI organises closure procedures by specific site, so there is no single ICHI code that represents closure as a generic, undifferentiated action.
228682002 (Cobalt 60 brachytherapy manual loading)(not mapped)ICHI does not contain a brachytherapy category code — only an extension concept ("Brachytherapy seeds") with no parent assignable code, and no codes for intracavitary/interstitial radiotherapy with specific isotopes (Co-60) or loading techniques.
312244008 (Cobalt 60 brachytherapy remote afterloading)(not mapped)As with manual loading brachytherapy, ICHI lacks any assignable category code for intracavitary/interstitial brachytherapy or for the distinction between manual and remote afterloading techniques; no candidate code provides even an approximate match.
229554006 (Combination therapy)(not mapped)"Combination therapy" is a high-level administrative concept describing the use of multiple concurrent treatment modalities; ICHI codes represent single, specific interventions and there is no composite or meta-level code for combined multi-modal treatment plans.
180062009 (Combined operations to separate conjoined twins)(not mapped)Separation of conjoined twins is a highly specialised and rare surgical concept involving coordinated multi-system operative procedures across two individuals simultaneously; ICHI contains no code or block addressing this unique scenario.
394935005 (Combined postoperative chemotherapy and radiotherapy)(not mapped)ICHI contains body-site-specific radiotherapy codes but no chemotherapy codes and no combined chemoradiotherapy concept; the postoperative context and the combination of two distinct oncological modalities cannot be represented by any single ICHI category.
133918004 (Comfort measures)(not mapped)"Comfort measures" is a broad clinical philosophy encompassing symptom relief, pain management, emotional support, and avoidance of curative interventions; ICHI lacks a palliative care or comfort-focused care umbrella code, and any single ICHI code would fail to capture the holistic multi-domain nature.
225423004 (Complementary therapy)(not mapped)ICHI does not have a single category or block representing "complementary therapy" as a grouping concept; individual complementary modalities exist as separate codes but no general category exists.
27219008 (Concurrent audit)(not mapped)ICHI has no code representing a clinical or concurrent audit (systematic review of care quality during ongoing patient care); the classification covers individual-patient interventions and public health actions, but not the organisational quality-assurance activity.
281131004 (Conservative therapy)(not mapped)ICHI does not have a code representing conservative management, watchful waiting, or non-interventional therapy as a category; this SNOMED concept describes a treatment philosophy rather than a specific intervention.
169274000 (Constant current for diagnosis)(not mapped)ICHI contains no code for galvanic/constant DC current diagnostic testing; the closest available concepts (peripheral nerve conduction, EMG, iontophoresis) are semantically distinct procedures and none approximates electrodiagnostic use of constant direct current.
281174001 (Construct dental special tray)(not mapped)ICHI does not classify the laboratory or clinical fabrication of dental appliances such as custom impression trays; the dental block (KAE) covers clinical interventions on teeth and jaws but contains no code for device construction or fabrication activities.
410614008 (Construction)(not mapped)"Construction" in SNOMED CT is a high-level abstract grouper concept with no specific clinical procedure content; ICHI has no equivalent grouper concept, and assigning any specific ICHI construction code would be arbitrarily narrower and semantically incorrect.
28191001 (Consultation and report by radiologist)(not mapped)ICHI contains no concept representing a specialist consultation or the act of a radiologist reviewing and reporting on imaging studies; the radiologist's interpretive/reporting role is outside ICHI's scope, which classifies the imaging procedure itself rather than the professional review service.
698309000 (Consultation for endoscopic procedure)(not mapped)This SNOMED concept describes a pre-procedure consultation prior to an endoscopy, an administrative/encounter-type activity; ICHI does not model pre-procedural consultations or procedure-specific consenting visits, and no ICHI code captures this semantic adequately.
31108002 (Consultation for laboratory medicine)(not mapped)A consultation for laboratory medicine is a specialty-level encounter (e.g., a pathologist consulted about lab results); ICHI models specific laboratory tests and procedures but has no code representing a specialist consultation in the discipline of laboratory medicine.
698308008 (Consultation for malignant neoplasm disease)(not mapped)ICHI does not represent disease-specific consultations or oncology consultations as a code type, and no oncology assessment or counselling code exists in ICHI that captures the concept of a clinical encounter oriented to a malignant neoplasm diagnosis; the nearest candidate (PZB.AA.ZZ) is too broad to constitute a reasonable mapping.
698313007 (Consultation for minor operation)(not mapped)ICHI does not encode pre-procedural or peri-operative consultation as a distinct intervention category, and no code exists for a clinical encounter specifically conducted in relation to a planned minor surgical procedure.
60664002 (Control of oropharyngeal hemorrhage)(not mapped)The ICHI oral pharynx block (BlockL5-KAR) contains no haemostasis or bleeding-control category, and the only oropharyngeal haemorrhage codes in ICHI (DAA.LA.AC, DAB.LA.AC) are restricted to post-tonsillectomy and post-adenoidectomy bleeding respectively, not general oropharyngeal haemorrhage control.
28174000 (Control of postoperative hemorrhage of pleural cavity)(not mapped)The ICHI pleural cavity block (BlockL5-JCB) and pleura block (BlockL5-JCA) contain only drainage, biopsy, excision, and repair codes — no haemorrhage control or haemostasis code exists for the pleural cavity or thoracic spaces in ICHI.
179524004 (Conversion to prosthetic interposition arthroplasty)(not mapped)ICHI does not contain an arthroplasty or joint replacement category at any site — joint-specific blocks (e.g., MLJ for hip, MMJ for knee) include implantation and repair codes but none representing prosthetic interposition arthroplasty as a distinct procedure type, and there is no site-agnostic joint arthroplasty code available.
385722003 (Coping support)(not mapped)ICHI does not contain a code for "coping support" as a distinct intervention category. The closest ICHI concepts are narrow body-function-specific codes such as "Emotional support for global psychosocial functions" (ATF.RC.ZZ) or "Counselling for global psychosocial functions" (ATF.PP.ZZ), but none of these captures the broader, non-function-specific concept of coping support as intended by the SNOMED term.
1230067007 (Correction of congenital anomaly)(not mapped)This SNOMED concept is an extremely broad category covering correction of any congenital anomaly across any body system; no single ICHI code or block captures this level of abstraction, and assigning any specific ICHI code would misrepresent the intent.
56306000 (Cosmetic surgery)(not mapped)ICHI encodes specific surgical procedures on individual anatomical targets (e.g. augmentation mammoplasty, liposuction of face) but has no overarching category for "cosmetic surgery" as a class of procedure. The SNOMED concept is a category label covering an entire domain of procedures, and no single ICHI code adequately represents this without being either too narrow or completely unrelated.
386250009 (Cost containment)(not mapped)"Cost containment" is a health-systems management concept; while ICHI's environment/services chapter (UEP, UEM blocks) covers health services policy interventions and economic incentives, none of these codes captures the specific management action of containing costs. The concept sits outside the scope of ICHI's assignable categories.
711136008 (Count of instruments and sponges)(not mapped)This concept describes a perioperative patient safety procedure (surgical instrument and sponge counting) that has no equivalent in ICHI; ICHI does not appear to classify intraoperative quality and safety checks of this type, and no synonym search — including surgical safety, checklist, verification, assessment, or perioperative — returned a relevant code.
118292001 (Removal)(not mapped)"Removal" is an abstract, top-level SNOMED concept with no target, action, or means specified; ICHI codes always require a defined target body structure or entity, so no single ICHI code can represent this undifferentiated concept.
711548004 (Ultrasonography guided insertion of gold seed marker)(not mapped)ICHI contains no code for fiducial or gold seed marker insertion; the concept is a highly specific interventional radiology/radiation oncology procedure with no equivalent category or closely related assignable code in the classification.
363335003 (Ultrasound studies by site)(not mapped)This SNOMED concept is a high-level grouper for all site-specific ultrasound studies; ICHI organises ultrasound codes individually by anatomical target with no single umbrella code, so no reasonable single ICHI code can represent this aggregator concept.
1304128005 (Verification of identity)(not mapped)ICHI does not contain any code covering patient identity verification, administrative, or patient-safety checking procedures — this is an administrative activity outside ICHI's scope.
473207004 (Assessment of need for interpreter)(not mapped)ICHI contains no code representing assessment of communication barrier needs or interpreter requirements; the language-related codes (e.g., AUI.AA.ZZ — assessment of mental functions of language) address the patient's own language function, not identification of a service need for a translator.
763084006 (Creation of mold for custom made foot orthosis)(not mapped)ICHI does not contain a code for manufacturing or casting a mold as a preparatory step for a custom orthosis; the environment section (UAE, UAD) covers installation, provision, and training for mobility/daily living products but not the fabrication of a mold itself. No reasonably close ICHI category exists for this pre-fabrication activity.
278415002 (Creative therapy)(not mapped)The ICHI "Creative therapy" entry (BlockL2-XG0) is a non-assignable extension code block used to tag other interventions with modifiers such as art or music therapy; there is no assignable ICHI category code representing creative therapy as a standalone health intervention.
265640003 (Crede placental expression)(not mapped)The Crede manoeuvre (external fundal compression to expel the placenta) has no dedicated ICHI code; the closest candidate NMM.JE.AC refers specifically to internal manual removal of a retained placenta and is semantically distinct enough that mapping would be misleading.
270113003 (Cremation certification)(not mapped)Cremation certification is an administrative-legal act and falls entirely outside ICHI's scope, which covers health interventions; no category or block in ICHI corresponds to issuing death or cremation documentation.
60726007 (Crushing)(not mapped)"Crushing" is a generic procedural technique/means, not a named intervention in ICHI; ICHI has no action axis entry for mechanical crushing and no category code that represents crushing as a standalone procedure without a specific target or clinical context.
56274004 (Cryoprecipitate thawing and pooling)(not mapped)ICHI has no terminology for cryoprecipitate processing — there is no concept for thawing or pooling blood fractions; the blood block (BlockL4-DIA) contains only transfusion, apheresis, and collection codes. This blood-bank laboratory procedure has no reasonable ICHI equivalent.
28680007 (Cryopreservation for genetic studies)(not mapped)ICHI contains no codes for cryopreservation or specimen preservation of any kind, nor does it have procedures specifically oriented toward genetic analysis beyond genetic counselling (PYA.PP.ZZ); this laboratory/biobank procedure has no assignable ICHI equivalent.
440645004 (Cryopreservation of oocyte)(not mapped)ICHI covers oocyte retrieval (NMA.JH.AB/AC) but has no code for the subsequent laboratory step of cryopreserving retrieved oocytes; cryopreservation as a preservation technique does not appear anywhere in the ICHI classification.
439790009 (Cryopreservation of ovarian tissue)(not mapped)The ovary block (BlockL5-NMA) contains surgical interventions on the ovary such as biopsy and partial excision, but none of these capture the cryopreservation step; the preservation and banking of excised ovarian tissue is not represented in ICHI.
870572003 (Cryopreservation of spermatozoa)(not mapped)ICHI codes NGD.AH.XE (specimen collection of sperm) and NGD.JH.AC (sperm procurement) cover only the retrieval step; the post-retrieval cryopreservation and banking of spermatozoa is not represented anywhere in the ICHI classification.
439247007 (Cryopreservation of testicular tissue)(not mapped)ICHI does not classify cryopreservation or biological tissue banking — these are laboratory preservation procedures outside ICHI's scope of clinical health interventions. No code for freezing, preservation, or storage of any biological specimen exists in ICHI.
21210003 (Cryopreservation technique with DMSO)(not mapped)ICHI has no representation of cryopreservation techniques, laboratory cryoprotectant agents (such as DMSO), or biobanking procedures at any level of the hierarchy. This SNOMED concept describes a laboratory technique entirely outside ICHI's classification scope.
72980003 (Cryopreservation technique with glycerol)(not mapped)As with other cryopreservation techniques, ICHI contains no codes for freezing/preservation procedures or cryoprotectant-specific methods such as glycerol-based cryopreservation. This concept has no reasonable ICHI counterpart.
26782000 (Cryotherapy)(not mapped)ICHI encodes tissue destruction by site (e.g., destruction of cranial nerve, destruction of skin lesion) but does not have a generic, site-unspecified "cryotherapy" code, and "cold" or "cryo" does not appear as a named means axis in any accessible code. Without a target site, no ICHI code can be assigned.
430269006 (CT guided ablation)(not mapped)CT-guided ablation is a guidance-modality-and-technique descriptor that applies across many different target tissues; ICHI has no generic "CT-guided ablation" code, and mapping to any specific body-site ablation code (e.g. cardiac, endometrial) would impose a target that is not defined in this SNOMED concept. The concept is too underspecified for a meaningful ICHI match.
431842009 (CT guided insertion of drain)(not mapped)ICHI does not have a generic, body-site-unspecified "insertion of drain" category; drain-related codes are always anchored to a specific body target (e.g., pleural cavity, peritoneum), making it impossible to map a body-site-agnostic SNOMED concept to any single ICHI code.
429929004 (CT guided laser ablation)(not mapped)ICHI contains only organ-specific laser ablation codes (liver: KCA.GA.AH; brain: AAA.GA.AH), none of which match a body-site-agnostic CT-guided laser ablation concept. No generic cross-site laser ablation code exists in ICHI.
441200004 (Culture of embryo)(not mapped)ICHI's embryo/fetal block (NMR) covers in-vivo interventions only; ex-vivo laboratory culture of an embryo (an ART laboratory technique) has no corresponding ICHI code.
257787004 (Custom fitting)(not mapped)ICHI does not have a generic "custom fitting" procedure code. While ICHI contains isolated fitting codes for specific devices (e.g., penile prosthesis, dental appliance management), there is no overarching category for custom fitting of assistive products or equipment that would capture this broad SNOMED concept.
23379002 (Cyclotomy)(not mapped)Cyclotomy is an incision into the ciliary body, but ICHI's ciliary body block (BlockL5-BBD) does not include an incision/FA action code — the only available codes are biopsy, destruction, local excision, partial excision, bypass, and repair. No adequate match exists in ICHI.
52744009 (Cytochemical test)(not mapped)ICHI does not contain a code for cytochemical testing as a distinct procedure; the Essential laboratory tests block (BlockL1-XG1) and its children cover specific named lab tests but not cytochemical analysis as a category, and no fuzzy or synonym search produced a reasonable match.
8638007 (Cytopathology procedure, preparation of smear, nongenital source)(not mapped)ICHI contains only a cervical (genital) papanicolaou smear code and no assignable category for cytological smear preparation from nongenital sources such as sputum, urine, CSF, or respiratory secretions; no reasonable ICHI match exists.
308646001 (Death certification)(not mapped)Death certification is a medico-legal administrative act (completing a death certificate/cause-of-death statement) and has no equivalent in ICHI; the classification does not include legal documentation or vital registration procedures, and no browsing of health services, governance, or public health surveillance blocks yielded a reasonable match.
363049002 (Death notification)(not mapped)ICHI contains no codes representing administrative death notification acts (informing authorities, families, or registrars of a death). This is an administrative/legal process outside ICHI's scope of health interventions.
184280004 (Death notification - non-hospital source)(not mapped)As with the parent concept, ICHI has no codes for death notification of any kind, and this sub-variant specifying a non-hospital source has no ICHI equivalent whatsoever.
428413005 (Death verification)(not mapped)ICHI does not include a code for clinical verification or pronouncement of death; this act (confirming that a person has died) falls outside the classification's scope of health interventions targeting body systems, functions, or behaviours.
36777000 (Debridement)(not mapped)ICHI has no single generic "debridement" code — every debridement code specifies both a target tissue and an approach (e.g., MAA.JG.AA for skull, LAB.JG.AA for trunk skin), so the unspecified SNOMED concept cannot be mapped to any single ICHI category without losing or assuming information about the anatomical target.
44387004 (Decompression chamber therapy)(not mapped)ICHI contains no code for hyperbaric or decompression chamber therapy; searches for "hyperbaric", "decompression chamber", "pressure therapy", "barotrauma", and "oxygen therapy" (PZA.DD.AC) returned nothing semantically close — the generic oxygen therapy code does not capture the pressurised chamber modality that defines this intervention.
19484001 (Decompressive incision)(not mapped)ICHI does not have a generic cross-body-site "decompressive incision" concept; all incision codes are tied to specific anatomical targets (nerve, bone, vessel, etc.), and no single ICHI code represents the procedure at the level of abstraction intended by this SNOMED concept.
440942004 (Decrease temperature of infant incubator)(not mapped)ICHI does not contain any concept representing adjustment or regulation of an incubator device setting; the closest codes (PZA.SE.ZZ "Cooling of central body temperature" and PZA.SD.BQ "Warming of central body temperature") describe interventions applied directly to the patient's body, not manipulation of an external device environment. This SNOMED concept is a device-management action rather than a direct health intervention on a person, and no ICHI code covers it.
410540005 (Delivery length of stay booking)(not mapped)This SNOMED concept represents an administrative/logistical act — pre-booking a hospital length of stay for delivery — which is not a clinical health intervention. ICHI does not classify administrative scheduling or admission planning activities, so no reasonable ICHI mapping exists.
302997003 (Dental facebow record)(not mapped)A dental facebow record is a prosthodontic procedure to register the spatial relationship of the maxillary arch to the temporomandibular joints; ICHI has no code for this or any equivalent jaw-relation recording procedure, and the existing dental codes (KAE block) do not cover prosthodontic diagnostic registration techniques.
183466000 (Dermatology emergency hospital admission)(not mapped)ICHI classifies health interventions (clinical procedures, rehabilitation, public health actions) and does not represent administrative or organisational events such as hospital admissions; no code exists for an inpatient admission encounter in ICHI regardless of specialty or urgency.
120609008 (Destruction of lesion)(not mapped)ICHI structures destruction codes by specific anatomical target (e.g., destruction of lesion of brain, skin, colon) and has no body-site-agnostic "destruction of lesion" category; the SNOMED concept is a generic, site-unspecified grouper with no single equivalent ICHI code.
363063008 (Destruction of lesion by anatomic site)(not mapped)This SNOMED concept is a high-level grouping category representing the entire class of "destruction of lesion" procedures across all anatomic sites, not a specific procedure. ICHI does not have a corresponding overarching grouper code — it only has site-specific destruction codes (e.g., BCA.GA.AH, JAN.GA.AA), none of which represents this abstract parent concept.
91253006 (Destruction of lesion by ultrasound)(not mapped)ICHI has no code specifically for destruction of a lesion by ultrasound as a modality-defined procedure independent of anatomic site; searches for "ultrasound destruction", "HIFU", "focused ultrasound", and fuzzy variants returned no matching codes. ICHI codes for destruction are organised by anatomic target, not by means alone, so this modality-only SNOMED concept has no structural equivalent.
413199002 (Destruction of tissue)(not mapped)ICHI does not have a single assignable code for non-site-specific "destruction of tissue"; all ICHI destruction codes require a defined anatomical target. The GA action axis value ("Destruction") exists in ICHI but is not an assignable intervention code, and no meaningful single mapping can be made for this highly abstract SNOMED grouper concept.
363068004 (Destructive procedure by organ system)(not mapped)This is a high-level SNOMED organisational grouper defined only by the notion that a destructive procedure occurs within some organ system — it has no clinical specificity and no ICHI equivalent grouper exists. ICHI does not have cross-system or polyhierarchical grouper codes of this kind.
225957000 (Detecting complications early)(not mapped)"Detecting complications early" is an abstract clinical goal or care-management activity, not a discrete health intervention — ICHI contains no category representing surveillance or early complication detection as a stand-alone procedure. No ICHI code captures this concept with even approximate fidelity.
310425007 (Diabetes monitoring invitation)(not mapped)A "monitoring invitation" is an administrative outreach act — contacting a known patient to prompt attendance at a diabetes review — which sits outside ICHI's scope of health interventions. No ICHI code represents individual-level patient recall or appointment invitation.
183472000 (Diabetic emergency hospital admission)(not mapped)Hospital admission is an administrative pathway event, not a clinical intervention in the ICHI sense. ICHI does not classify admission acts, and no code captures the concept of being admitted to an inpatient ward for a diabetic emergency.
430280006 (Dilation using fluoroscopic guidance)(not mapped)ICHI encodes dilation at the level of a specific target organ with a specific means (e.g., KBA.LG.AC for oesophagus, HDE.LG.AF for aortic valve), and fluoroscopy appears only as the means in the single swallowing-study code (KTC.BA.BB). The SNOMED concept is a generic procedural method category — dilation of an unspecified structure with fluoroscopic guidance — for which ICHI has no cross-target generic equivalent.
117339008 (Dipstick colorimetric laboratory test method)(not mapped)This SNOMED concept describes a laboratory methodology (dipstick colorimetric analysis) rather than a specific intervention on a patient; ICHI does not classify analytical test methods or instrument techniques at this level of abstraction, and no matching ICHI assignable code exists.
306522005 (Discharge by midwife)(not mapped)ICHI does not contain a standalone code representing the administrative act of patient discharge by a specific clinician type. The only related ICHI concept, XG38D0 "Discharge planning," is an extension qualifier code (not an assignable category) that describes planning for discharge rather than the act of discharging a patient. Aligned with rows 3355–3361 (discharge-by-role concepts).
306492003 (Discharge by nurse)(not mapped)ICHI does not contain a standalone code representing the administrative act of patient discharge by a specific clinician type. The only relevant ICHI concept, XG38D0 "Discharge planning," is an extension qualifier code (not an assignable category), and it describes planning for discharge rather than the act of discharging a patient.
307838002 (Discharge by person)(not mapped)ICHI has no code representing discharge of a patient by any person; the SNOMED concept is an administrative act for which ICHI has no corresponding assignable category, and the extension code XG38D0 "Discharge planning" is not an equivalent substitute.
306416004 (Discharge by physician)(not mapped)ICHI does not model clinician-role-specific discharge acts as assignable codes; no category in ICHI corresponds to the act of a physician formally discharging a patient from a care episode.
306527004 (Discharge by professional allied to medicine)(not mapped)Like the other discharge-by-role concepts, this administrative act has no counterpart in ICHI as an assignable category; ICHI's scope for allied health professionals is limited to specific clinical interventions, not administrative discharge acts.
306526008 (Discharge by psychotherapist)(not mapped)ICHI contains many psychotherapy intervention codes (e.g., AS1.PQ.ZZ, PZB.PQ.ZZ) but none represent the administrative act of discharge by a psychotherapist; the clinician-role discharge concept is outside ICHI's classification scope.
306561002 (Discharge from establishment)(not mapped)ICHI contains only one discharge-related code, XG38D0 (Discharge planning), which is an extension code describing the preparatory planning activity, not the administrative act of discharging a patient from a care establishment. No ICHI assignable category captures the administrative event of formal separation from an inpatient or residential facility.
306562009 (Discharge from service)(not mapped)Like discharge from establishment, this concept represents an administrative endpoint event (ending a patient's formal enrolment in a service), for which no ICHI assignable category exists; XG38D0 is limited to the planning phase and does not cover discharge from an outpatient or community service specifically.
1251645009 (Discography with injection of contrast into intervertebral disc)(not mapped)ICHI has no code for discography or intradiscal contrast injection; the intervertebral disc blocks (MBB, MBH, MBN, MBV) cover only biopsy, excision, prosthesis, reduction, and destruction. Spinal imaging codes (e.g. MBA.BA.BC/BD) cover external CT/MRI with IV contrast, not intradiscal injection.
713056003 (Discussion about clinical red flag warning sign)(not mapped)ICHI contains no code for discussing, communicating, or advising about clinical red flag signs or alarm symptoms; this is a highly specific clinical communication act with no corresponding target, action, or combination in the ICHI classification.
713080004 (Discussion about do not attempt cardiopulmonary resuscitation clinical decision)(not mapped)ICHI covers cardiopulmonary resuscitation as a procedure (HT2.MC.AH) but has no code for the clinical communication act of discussing a DNAR/DNACPR decision; advance care planning conversations and goals-of-care discussions are absent from the classification.
704432005 (Discussion about euthanasia)(not mapped)ICHI has no code covering discussion, counselling, or advising specifically about euthanasia, assisted dying, or end-of-life decision-making of this nature; the classification does not include codes for medico-ethical discussions or legal aspects of deliberate ending of life.
707987008 (Discussion about last days of life)(not mapped)ICHI contains no code for discussions or counselling specifically about end-of-life, dying, or the last days of life; searches for palliative, death, dying, prognosis, and advance care planning returned no relevant results, and no sufficiently close proxy category exists.
734329007 (Discussion about writing Last Will and Testament)(not mapped)ICHI contains no code for clinical discussion about a legal document such as a Last Will and Testament; the legal services block (UEJ) covers policy-level legal interventions, not individual medicolegal discussions, and no other ICHI section addresses this highly specific social/legal activity within a health encounter.
409686004 (Disinfecting of equipment)(not mapped)ICHI has no codes for equipment disinfection or sterilization as a clinical procedure — the decontamination codes that exist (UB1.VL.ZZ, UBL.VL.ZZ, etc.) cover environmental remediation of outdoor/indoor air, water, and soil, not medical equipment. Instrument reprocessing is outside ICHI's scope of health interventions on persons or environments.
386770004 (Dissection of vascular bundle)(not mapped)ICHI does not have a generic cross-system "vascular bundle dissection" code — vascular interventions are always tied to a specific named vessel as the target axis, and no general vascular bundle target exists. The closest hit, "Radical neck dissection" (DFB.JL.AA), is a specific oncological procedure on the neck rather than a generic vascular bundle dissection.
118440007 (Dissection with preservation of nerve)(not mapped)ICHI contains only one dissection code (DFB.JL.AA — Radical neck dissection), which is a specific named procedure and does not represent the general concept of tissue dissection with nerve preservation. There is no ICHI code capturing dissection as a general intraoperative technique, nor any code expressing nerve preservation as an adjunct qualifier.
414039005 (Distraction)(not mapped)ICHI encodes distraction only in site-specific osteogenesis codes (MAF.LK.AA for maxilla, MAG.LK.AA for mandible); there is no general "distraction" category code covering the broad SNOMED concept, which encompasses mechanical distraction of joints, bones, or soft tissue across any body site.
118630004 (Division)(not mapped)ICHI encodes division only as named, site-specific categories (e.g., ACA.FB.AA Division of peripheral nerve, MMC.FB.AA Division of cartilage of knee) and has no parent "Division" category code representing the general action across all targets, which is what this SNOMED concept expresses.
23745001 (Documentation procedure)(not mapped)ICHI classifies health interventions acting on body systems, functions, behaviours, or environments; administrative documentation as a standalone procedure type has no corresponding ICHI category. Searches across documentation, recording, health records, data, and information yielded no applicable ICHI code.
167200003 (Duodenal aspirate analysis)(not mapped)ICHI contains no code for specimen collection from the duodenum or analysis of duodenal fluid; the duodenum block (KBI) covers only procedural interventions (endoscopy, excision, anastomosis, etc.) and there is no general specimen-collection code for intestinal fluid comparable to those that exist for pleural, peritoneal, or sinus sites. No reasonable proxy exists that does not introduce significant semantic distortion.
281175000 (Duplication of dental model)(not mapped)ICHI's dental block (KAE) covers clinical procedures such as examination, extraction, implants, and device application, but contains nothing that corresponds to the laboratory/technical act of duplicating a dental study model or cast. This is a dental-laboratory activity outside ICHI's scope at the level of assignable codes.
1285182002 (Early childhood intervention program)(not mapped)ICHI does not contain a concept for early childhood intervention programs as a structured multi-component service; searches across childhood, developmental, habilitation, community program, and related terms returned no applicable code. The SNOMED concept describes an organisational care delivery program that has no corresponding ICHI category.
390815004 (Early intervention in psychosis)(not mapped)ICHI does not have a code representing early intervention in psychosis as a program or service model; searches across psychosis, psychiatric, mental health, thought disorder, hallucination, antipsychotic, and global psychosocial functions found no code that captures the program-level construct of coordinated early psychosis treatment. Individual ICHI codes (e.g. counselling, training) cover sub-components but none match the overarching SNOMED concept.
440169004 (Education of school staff about medical condition of subject)(not mapped)ICHI has no code representing education directed at a third party (school staff) about a patient's medical condition; all ICHI "Education about" codes target the patient or their function/activity domain, not non-clinical staff in a school context. The closest candidates (e.g., STE.PM.ZZ, UCH.PM.ZZ) do not capture the concept of informing school personnel about a specific individual's health condition.
169275004 (Electric pulses for diagnosis)(not mapped)No ICHI code exists for generic diagnostic use of electric pulses as a category. ICHI encodes specific electrical diagnostic modalities individually (e.g., nerve conduction studies, EMG, EEG, evoked potentials), but there is no parent code capturing "electric pulses for diagnosis" as a general or unspecified concept.
1287559006 (Electrocoagulation of arteriovenous fistula)(not mapped)ICHI has no dedicated code for destruction or electrocoagulation of an arteriovenous fistula; the vascular intervention blocks cover occlusion, repair, and excision of named vessels but do not include a concept targeting an AV fistula as a distinct pathological structure. No sufficiently close approximation exists.
223306006 (Electrocoagulation of broad ligament)(not mapped)ICHI does not include an interventions block for the broad ligament; it appears only as an extension anatomy term (XA0EJ9) with no associated procedure codes, and there is no NEC destruction code that targets periuterine ligamentous structures.
39174001 (Electrocoagulation with curettage)(not mapped)ICHI has no combined "electrocoagulation with curettage" concept at any body site; the two procedural components (electrical destruction + mechanical scraping) do not correspond to any single assignable ICHI category, and ICHI curettage codes (NME.JB.AC, NME.JE.AC) are limited to the uterus and do not encode the combined electrosurgical technique.
8401003 (Electrodesiccation)(not mapped)Electrodesiccation is a specific electrosurgical technique applied across many body sites (commonly skin), but ICHI carries no generic body-site-independent destruction code and no means value encoding electrodesiccation specifically; site-specific skin destruction codes (e.g. LAA.GA.AH, LAB.GA.AH) each cover a defined anatomical region and none captures the concept as a body-site-neutral technique.
103720008 (Elevation)(not mapped)"Elevation" as a standalone SNOMED concept is too non-specific (it could refer to elevation of a body part, a fracture fragment, blood pressure elevation, or a positional manoeuvre) and ICHI has no generic "elevation" code; the only ICHI elevation code (MAA.LC.AA) is specific to skull fracture fragments, which is not a valid representation of this undifferentiated concept.
386278005 (Elopement precautions)(not mapped)Elopement precautions — measures to prevent at-risk patients (e.g. with dementia) from leaving care unsupervised — have no corresponding ICHI code; ICHI has no safety-monitoring or risk-mitigation precaution category for this type of nursing/care management intervention, and neither surveillance, isolation, nor observation codes adequately capture the concept.
386282007 (Emergency cart checking)(not mapped)Emergency cart (crash cart) checking is a health systems safety/readiness activity — an inspection of resuscitation equipment — and ICHI contains no code for equipment inspection, readiness checks, or administrative safety procedures of this kind.
183478001 (Emergency hospital admission for asthma)(not mapped)ICHI does not classify acts of hospital admission or triage events as interventions — it codes the clinical procedures performed, not the administrative/organisational act of admitting a patient; no ICHI code exists for an emergency inpatient admission event.
385866009 (Emergency treatment assessment)(not mapped)ICHI has no concept for emergency-context clinical assessment or triage; the classification does not encode urgency or care-setting modifiers as standalone intervention codes, and no ICHI code covers the activity of assessing a patient for emergency treatment specifically.
385868005 (Emergency treatment management)(not mapped)ICHI does not represent emergency treatment management as a discrete intervention; urgency modifiers and administrative care-management activities of this type are outside the ICHI classification scope.
371018001 (Empirical therapy)(not mapped)"Empirical therapy" is a clinical decision-making concept (initiating treatment before diagnostic confirmation, typically empirical antibiotic use) that describes a therapeutic strategy rather than a specific intervention type; ICHI does not have a code for this prescribing approach.
225347007 (Empowerment)(not mapped)"Empowerment" is a conceptual/meta-level intervention approach rather than a discrete classifiable health intervention, and ICHI has no code representing it; the closest ICHI constructs (education, counselling, advocacy, capacity building) each capture only one facet of the empowerment concept, making any single code a misrepresentation.
225175003 (Emptying stoma bag)(not mapped)Emptying a stoma bag is a routine nursing/self-care task and ICHI contains no code for this activity; ICHI covers the surgical creation and revision of stomas (e.g., colostomy, ileostomy) but not the ongoing appliance-emptying task that follows.
107989000 (Endocrine system manipulation)(not mapped)ICHI has no manipulation action code for endocrine structures, and even the residual system-level codes (EZZ.ZZ.ZZ, EZZ.ZY.ZY) do not approximate a manipulation procedure; no reasonable ICHI match exists for this concept.
473275008 (Endoscopic control of hemorrhage of pharynx)(not mapped)ICHI has no dedicated code for endoscopic hemorrhage control of the pharynx; the pharynx blocks (KAR oral pharynx, JAM nasopharynx) contain no occlusive/bleeding-control actions, and the only comparable pattern in ICHI (endoscopic control of bleeding) is limited to gastrointestinal and biliary sites.
363105001 (Endoscopic dilation)(not mapped)ICHI has no generic "endoscopic dilation" code — all dilatation codes are tied to a specific anatomical target (e.g. KBA.LG.AD oesophagus, KBP.LG.AD colon, JAN.LG.AD larynx). This SNOMED concept is a high-level procedure category with no anatomical specification, and ICHI's structure requires a target axis, so no single ICHI code can represent it.
179860003 (Endoscopic drilling of lesion of articular cartilage)(not mapped)ICHI does not contain a code for drilling or microfracture of articular cartilage; the knee cartilage block (MMC) only offers division, procurement, repair, and chondrocyte transplantation, none of which capture the specific action of subchondral drilling. No anatomically non-specific cartilage drilling code exists elsewhere in ICHI.
274493004 (Endoscopic manipulation)(not mapped)ICHI contains no generic "endoscopic manipulation" code; organ-specific endoscopic manipulation/reduction codes exist (e.g., KBP.LD.AD for colon) but none covers the unspecified, body-site-neutral concept that this SNOMED code represents.
28309003 (Endoscopy and catheterization)(not mapped)This SNOMED concept combines two distinct procedural actions (endoscopy and catheterization) into a single generic grouping code; no ICHI category or block represents this combination, and mapping to either action alone would misrepresent the compound nature of the concept.
83494009 (Endoscopy of inguinal region)(not mapped)ICHI has no endoscopy/inspection code for the inguinal region as an anatomical territory; the PAM block (Interventions on abdominal wall, inguinal) contains only hernia repair codes, and there is no generic soft-tissue or region-level endoscopic inspection code in ICHI corresponding to this concept.
25645009 (Endoscopy of perineum)(not mapped)The PAW block (Interventions on perineum) contains no endoscopy or inspection code; the available perineum codes cover biopsy, drainage, debridement, repair, and episiotomy, none of which represent a diagnostic endoscopic inspection of the perineum.
385709006 (Enema administration assessment)(not mapped)ICHI contains enema codes only as therapeutic reduction procedures (e.g., KBP.LD.AC reduction of colon by enema), not as a clinical assessment of enema administration; no ICHI code represents the nursing evaluation activity described by this SNOMED concept.
440307006 (Enhanced elimination procedure)(not mapped)"Enhanced elimination" is a clinical toxicology concept encompassing techniques such as multi-dose activated charcoal, urinary alkalinisation, and haemoperfusion to accelerate poison/drug clearance. ICHI has no code capturing this category — dialysis codes cover only specific modalities, and no grouping code exists for the broader concept of accelerating substance elimination.
183462003 (ENT emergency hospital admission)(not mapped)ICHI does not classify hospital admissions, emergency encounters, or specialty-specific care episodes as intervention types; the administrative act of admitting a patient to an ENT ward is outside ICHI's scope of assignable intervention codes.
74476001 (Epidermal occlusion therapy)(not mapped)"Epidermal occlusion therapy" (eye patching for amblyopia treatment) has no corresponding ICHI concept — searches across occlusion, eye patching, amblyopia, skin occlusion, and visual functions blocks yielded no matching procedure. ICHI does not represent this non-surgical therapeutic technique.
284036006 (Equipment monitoring)(not mapped)ICHI does not contain a code for generic equipment monitoring (i.e., checking or surveillance of health-related devices or equipment). The ICHI environment/products blocks (U section) cover interventions on products and technology in public health or environmental contexts, none of which match the clinical activity of monitoring patient-use equipment.
398045004 (Estimation of regional perfusion)(not mapped)ICHI contains no general code for estimation or assessment of regional perfusion; the only perfusion-related code (HTC.BA.BE, Myocardial perfusion scan) is restricted to cardiac territory and does not represent a generic or region-neutral perfusion estimation procedure.
91130003 (Euthanasia by barbiturate)(not mapped)ICHI contains no code for euthanasia or intentional life-ending interventions using any pharmacological agent; searches for euthanasia, barbiturate, lethal, and end-of-life returned no results, confirming this concept is outside ICHI's coded scope.
122461007 (Evacuation procedure)(not mapped)"Evacuation procedure" in SNOMED CT is a high-level grouper (removal of unwanted material — fluid, tissue, foreign body) with no single ICHI counterpart; ICHI represents evacuation-type actions through specific site-and-action combinations (drainage, aspiration, debridement) each assigned to a distinct body target.
441817003 (Evaluation of biopsy specimen)(not mapped)ICHI codes biopsy as a procedural act on a specific anatomical target, not as a downstream laboratory evaluation of the excised specimen. Post-biopsy specimen analysis (histopathology review) falls outside ICHI's procedural scope; XG30Q5 "Histopathology" exists only as an extension code, not an assignable intervention category.
711138009 (Evaluation of count of instruments and sponges procedure)(not mapped)This SNOMED concept represents a perioperative surgical safety activity (instrument/swab count) that has no corresponding assignable category in ICHI; searches across surgical safety, perioperative, quality, checklist, and surgical management domains returned no relevant results.
1259019001 (Evaluation of eligibility for adult learning center)(not mapped)ICHI contains no concept for assessing an individual's eligibility for an educational facility; the UEQ block (education and training services) lacks any individual-level eligibility assessment code, and the closest system-level code (UE1.AA.ZZ) addresses population/policy contexts rather than individual clinical evaluations.
472061000124107 (Evaluation of eligibility for program)(not mapped)ICHI does not classify individual patient eligibility screening for an unspecified program; no environmental or clinical code captures this concept, and the services/systems assessment codes in the U block target population-level or policy-level actions rather than individual eligibility determinations.
58001000087106 (Evaluation of procedures relating to control, restraint and seclusion)(not mapped)ICHI contains no codes for evaluating or auditing the use of restraint, seclusion, or coercive control procedures; searches across all relevant synonyms (restraint, seclusion, coercion, procedure evaluation, clinical audit) returned no results. This concept sits in the quality/safety governance domain that ICHI does not cover.
711125001 (Evaluation of satisfaction with healthcare)(not mapped)ICHI does not include codes for patient experience measurement or satisfaction surveys; searches for "patient satisfaction," "health care quality," "quality care," and related terms across the U (environment/health services) and other blocks yielded no relevant categories. This is a healthcare quality/feedback domain outside ICHI's scope.
363109007 (Evaluation of test results)(not mapped)ICHI does not include a code for reviewing or interpreting previously collected test results — this is a clinical decision-support or data-review activity rather than a health intervention on a body target, action, or means. No laboratory result review, test interpretation, or equivalent concept exists anywhere in the ICHI hierarchy.
711139001 (Evaluation of tubes and drains)(not mapped)ICHI codes for tubes and drains are procedure-specific (e.g., insertion, replacement, removal of a named device at a specific body site) and there is no generic "evaluation/assessment of tubes and drains" category. The concept describes a nursing/clinical surveillance activity that falls outside ICHI's structured intervention model.
442030001 (Evaluation of vomitus specimen)(not mapped)ICHI's specimen collection codes cover blood, urine, faeces, sputum, saliva, pleural fluid, and a small number of other named specimens, but vomitus/emesis is absent from the classification entirely. No specimen collection code (PZX.AH.ZZ NEC or otherwise) is specific enough to constitute a reasonable match, and there is no evaluation-of-specimen category in ICHI at all.
409077008 (Examination for xanthochromia)(not mapped)Xanthochromia detection is a specific laboratory/visual examination of cerebrospinal fluid for bilirubin pigmentation (indicating subarachnoid haemorrhage); ICHI has no code for CSF analysis, xanthochromia, or any sufficiently related CSF examination procedure, and the only CSF entry (XA1N55) is an extension code target, not an assignable intervention code.
365681005 (Examination of cells)(not mapped)ICHI contains no code corresponding to cytological or cellular examination as a standalone procedure — the only cell-related term found (XG4JJ6 "Cytology") is a classification concept, not an assignable intervention code, and no assessment code targeting cells at a cytological level exists in the classification.
118131001 (Examination of specimen for hemolysis)(not mapped)ICHI does not contain codes for laboratory specimen analysis or hemolysis testing; its specimen-related codes cover only specimen collection (AH axis), not downstream laboratory analysis of a specimen. No reasonable ICHI match exists for this concept.
118132008 (Examination of specimen for icterus)(not mapped)ICHI does not classify pre-analytical specimen quality checks such as visual inspection for jaundice/icterus (bilirubin discolouration); this is a laboratory specimen adequacy assessment with no corresponding ICHI intervention code. No search across icterus, jaundice, bilirubin, specimen, visual inspection, or macroscopic terms returned a relevant result.
118130000 (Examination of specimen for lipemia)(not mapped)Like its icterus counterpart, this is a pre-analytical specimen turbidity check and ICHI has no code for macroscopic or visual specimen quality assessment; searches on lipemia, lipid, turbidity, serum, and specimen examination all failed to yield a relevant match.
239529002 (Exchange of bearing component of arthroplasty)(not mapped)ICHI encodes joint device replacements at the level of specific joints (e.g., MLJ.KA.AA for hip, MMJ.KA.AA for knee) but has no generic cross-joint code for replacing a bearing component of an arthroplasty; the SNOMED concept is intentionally joint-agnostic and no single ICHI code captures that scope.
65801008 (Excision)(not mapped)"Excision" is an extremely broad, non-specific SNOMED concept representing a class of procedures with no defined body target; ICHI codes require a specific anatomical target (the first three characters of the axis), so no single ICHI category or block is a valid equivalent for an unqualified excision action.
128993003 (Excision of head structure)(not mapped)"Head structure" in SNOMED is an extremely broad high-level anatomical category encompassing any structure of the head (skull, brain, vessels, nerves, muscles, sensory organs, etc.), and no single ICHI code can represent excision of such a generic and heterogeneous concept. This SNOMED concept is a classifier node rather than a specific procedure, and ICHI has no corresponding catch-all code.
433016000 (Excision of ligament)(not mapped)ICHI has no generic, site-nonspecific ligament excision code — all ligament excision codes are tied to a specific anatomical region (shoulder, wrist, knee, foot, etc.), whereas the SNOMED concept is a generic procedure category with no body-site specified. No single ICHI code or block adequately represents this unlocalized concept without arbitrarily assigning a site.
438758006 (Expectant management)(not mapped)ICHI does not contain a concept for watchful waiting or expectant management — its observation and monitoring codes are all tied to specific body systems or functions (e.g., cardiac monitoring, EEG monitoring) and none represents the clinical strategy of deferring active treatment while awaiting natural resolution. No reasonable single ICHI code covers this concept.
76145000 (Exploratory incision)(not mapped)ICHI does not contain a generic, site-unspecified "exploratory incision" code; all ICHI incision and exploration codes are tied to specific body structures or sites, and no available code captures the procedurally generic, non-site-specific nature of this SNOMED concept.
304889007 (Exposure technique)(not mapped)"Exposure technique" in SNOMED refers to radiographic exposure parameters (a technical qualifier rather than a health intervention), which falls entirely outside the scope of ICHI; ICHI classifies imaging procedures by anatomical target and modality but does not represent radiographic technique settings as codeable interventions.
77613002 (External beam radiation therapy with iodine-125)(not mapped)Iodine-125 is a radioisotope used in brachytherapy (internal seed implantation), not in external beam radiation therapy, making this SNOMED concept clinically contradictory. ICHI has no generic cross-target external beam radiotherapy code, only target-specific destruction-by-radiotherapy codes, and none capture this modality combination.
37539001 (Fascial sling for facial weakness)(not mapped)No ICHI code describes a fascial sling procedure specifically for facial weakness or facial palsy — ICHI has no "sling" procedure concept for the face, and facial nerve intervention codes cover graft, repair, anastomosis, and transposition of the nerve itself rather than soft-tissue sling suspension of facial musculature; no adequate proxy preserves the anatomical specificity and procedural intent.
281106000 (Fecal starch test)(not mapped)The fecal starch test (a microscopy test for undigested starch granules in stool, used to assess malabsorption/pancreatic exocrine insufficiency) has no corresponding code in ICHI — the only faecal laboratory test coded is the faecal immunochemical test (XG5WC5), which is immunological rather than starch-based, and the broader essential laboratory tests block does not include starch testing.
179002007 (Fenestration of cortex of bone)(not mapped)ICHI contains no code for fenestration or windowing of the cortex of bone (a procedure used to decompress or access the medullary cavity); osteotomy codes represent complete bone cuts for realignment, not cortical fenestration, and no fuzzy or hierarchical search produced a semantically adequate match.
90564003 (Field block design and fabrication)(not mapped)A field block is a local anaesthetic technique involving infiltration around a surgical site; ICHI has no dedicated field block or local infiltration anaesthesia category, and no code captures the design/fabrication component.
15719007 (Fine needle aspirate with routine interpretation and report)(not mapped)ICHI's aspiration and biopsy codes are all site-specific (thyroid, orbit, bladder, etc.) with no site-independent generic FNA code, and the bundled SNOMED concept (specimen collection + cytological interpretation + report) has no ICHI equivalent.
115980008 (Fixation by staple)(not mapped)ICHI contains no codes for surgical staple fixation of tissue or bone; the only ICHI entries containing "staple" relate to fortification of staple foods (a public health context entirely unrelated to the surgical technique). No reasonable ICHI equivalent exists.
238341001 (Fixation of costal cartilage)(not mapped)ICHI has no specific code for fixation of costal cartilage. The thoracic cage block (MCB) covers only bone of the thoracic cage with no cartilage fixation procedure, and the chest wall block (PAF) does not include a fixation action; no LC (fixation) action is assigned to any chest wall or costal cartilage target in ICHI.
787378005 (Fixation of specimen)(not mapped)"Fixation of specimen" refers to a histopathological/laboratory processing step (e.g., formalin fixation of tissue) performed outside the patient, which is outside the scope of ICHI's clinical intervention classification. No ICHI code exists for laboratory specimen processing of this type.
64444005 (Flow cytometry)(not mapped)The only flow cytometry code in ICHI (XG5FX1) is an extension code specifically for an essential panel of antibodies for leukaemia diagnosis, making it far too narrow for general flow cytometry as a diagnostic laboratory technique. No assignable ICHI category code covers flow cytometry as a general procedure.
168147001 (Fluid sample analysis)(not mapped)ICHI contains `XE` (Fluid sample) only as a Means axis extension code, not as an assignable intervention code; no ICHI category code represents the act of analysing a fluid sample, making a meaningful mapping impossible.
282721001 (Fluoroscopic guidance)(not mapped)ICHI does not represent imaging modality guidance as a standalone procedure code; fluoroscopy (X-ray) is only implicit in some means codes and the sole fluoroscopy-related ICHI category (KTC.BA.BB) is limited to swallowing evaluation, so no reasonable ICHI match exists for fluoroscopic guidance as an independent concept.
715914001 (Fluoroscopy guided insertion of catheter into cecostomy)(not mapped)ICHI has no code for catheter insertion into a cecostomy (or caecostomy); the colon interventions block (KBP) does not include percutaneous or fluoroscopy-guided catheter placement into a pre-existing stoma, and no suitable NEC code covers this specific procedure.
433030005 (Fluoroscopy guided replacement of pulmonary artery catheter with contrast)(not mapped)ICHI has no code representing replacement of a pulmonary artery (Swan-Ganz) monitoring catheter; the pulmonary artery block (BlockL5-HID) contains only surgical and endovascular interventions on the artery itself, and no ICHI category covers the clinical procedure of replacing a haemodynamic monitoring catheter positioned in the pulmonary artery under fluoroscopic guidance.
6343004 (Forensic bite mark comparison technique)(not mapped)Forensic bite mark comparison is a specialised forensic odontology/criminalistic analysis technique with no equivalent in ICHI, which does not include forensic investigative methods.
186051000 (Formal complaint about GP)(not mapped)Filing a formal complaint about a general practitioner is an administrative/regulatory act by a patient or relative, not a health intervention as classified by ICHI; no ICHI code covers complaint lodgement.
186053002 (Formal complaint about GP RE: relative)(not mapped)A formal complaint on behalf of a relative is an administrative/regulatory action outside the scope of ICHI health interventions; no applicable ICHI category covers patient-rights complaint activity.
186052007 (Formal complaint about GP RE: self)(not mapped)A formal complaint about a GP concerning oneself is an administrative complaint act, not a health intervention; ICHI has no code for patient complaint lodgement.
186054008 (Formal complaint about hospital care)(not mapped)A formal complaint about hospital care is an administrative/governance act by a patient or representative, not a health intervention; ICHI does not classify individual complaint actions against healthcare institutions.
186056005 (Formal complaint about hospital care RE: relative)(not mapped)ICHI contains no concept representing the act of lodging a formal complaint about received health care. This concept describes an administrative/rights-based action that falls outside ICHI's coded intervention scope.
186055009 (Formal complaint about hospital care RE: self)(not mapped)ICHI contains no concept for a patient filing a formal complaint about their own hospital care. The classification covers health interventions delivered to or for patients, not patient-initiated administrative complaints.
186050004 (Formal complaint about medical care)(not mapped)No ICHI code represents the act of making a formal complaint about medical care in general. ICHI's health services domain covers interventions such as assessment of health systems, advocacy, and policy change — not patient grievance filing.
186057001 (Formal complaint about private specialist)(not mapped)ICHI does not capture complaints directed at specific provider types such as private specialists. The action axis has no "complaint" or "grievance" action code.
186059003 (Formal complaint about private specialist RE: relative)(not mapped)This represents a patient's relative lodging a formal complaint — an administrative act with no corresponding ICHI code. The "on behalf of a relative" qualifier adds further specificity that ICHI cannot represent.
186058006 (Formal complaint about private specialist RE: self)(not mapped)This describes an administrative/legal action — filing a formal complaint about a private specialist — which falls entirely outside the scope of ICHI clinical and health intervention coding.
24278000 (Fragmentation procedure)(not mapped)"Fragmentation procedure" in SNOMED is a high-level grouping concept for any procedure that breaks apart a structure (calculi, tissue, emboli), not a specific procedure. The only fragmentation code in ICHI (BBF.GA.AA) is narrowly specific to ocular lens secondary membrane, and no general or multi-system fragmentation category exists.
24519004 (Free radical assay technique measurement)(not mapped)ICHI does not include laboratory biochemical assays for reactive oxygen species or free radicals; the essential laboratory tests block covers only a limited set of WHO-priority tests, and no oxidative stress or free radical measurement code exists.
18312004 (Fresh frozen plasma preparation)(not mapped)The blood interventions block contains only specimen collection, transfusion, apheresis, and general blood product collection codes, and none covers laboratory preparation or processing of fresh frozen plasma as a distinct procedure.
26245005 (Fresh frozen plasma thawing)(not mapped)Thawing of frozen plasma is a blood bank processing step that is not represented anywhere in ICHI; the classification does not model sub-steps of blood product preparation such as thawing.
71643009 (Frozen blood preparation)(not mapped)ICHI does not contain a code for the preparation or processing of frozen blood products; the closest codes (DIA.DG.AF, DIA.JH.AF) represent clinical acts of transfusion or collection, not the laboratory/blood-bank preparation step of freezing blood.
118629009 (Functional training)(not mapped)"Functional training" in the SNOMED sense is a broad rehabilitation concept spanning training of body functions and activities across multiple domains; ICHI has no single code representing this aggregate concept, and the available training codes (e.g. SJA.PH.ZZ for walking, MTB.PH.ZZ for joint mobility) each cover only specific functions rather than the general rehabilitative meaning of the SNOMED term.
1343419009 (Gamma radiation brachytherapy using surface mold applicator)(not mapped)ICHI's radiotherapy codes (GA.BA series) are all body-site specific and require a known target organ; this SNOMED concept specifies a delivery technique (surface mold applicator with gamma radiation brachytherapy) without a specified target, and no ICHI code captures brachytherapy as a technique independent of target site.
228685000 (Gammamed brachytherapy)(not mapped)Gammamed is a specific high-dose-rate afterloader device used in brachytherapy; ICHI's radiotherapy codes are body-site specific (GA.BA series) and none captures brachytherapy as a device-type or technique concept independent of anatomical target, leaving no reasonable single ICHI code available.
118159000 (Gastrointestinal tract transposition)(not mapped)ICHI contains no transposition codes for any gastrointestinal structure — transposition (LJ action) is only coded for cranial nerves, peripheral nerves, extraocular muscles, and salivary gland ducts. There is no applicable code at the category or block level.
444310005 (Gene tracking)(not mapped)ICHI's genome block (BlockL4-PYA) contains only one code, PYA.PP.ZZ (Genetic counselling), and no code exists for gene tracking — the diagnostic/surveillance process of following specific genetic markers or mutations through a family or population. The concept has no reasonable ICHI equivalent.
363779003 (Genotype determination)(not mapped)ICHI has no assignable code for genotype or genotyping procedures; the only code in the "Interventions on genome" block (BlockL4-PYA) is PYA.PP.ZZ (Genetic counselling), which is a counselling/support intervention rather than a laboratory or diagnostic determination procedure.
183457004 (Geriatric emergency hospital admission)(not mapped)ICHI does not classify care pathways, patient admission events, or encounter types — it classifies health interventions (procedures, treatments, assessments). No ICHI code represents hospital admission as an act, and there is no geriatric-specific or emergency-specific admission intervention in the classification.
225073008 (Giving mouth wash)(not mapped)ICHI has no code representing the clinical act of administering a mouth wash or oral rinse; the oral cavity intervention codes (KAZ block) cover surgical/procedural acts, and the oral hygiene behaviour block (VEE) addresses population-level behaviour change rather than a direct patient-care act of giving mouth wash.
391541008 (Glandular fever screening test)(not mapped)ICHI's essential laboratory tests block (BlockL1-XG1) does not include a code for infectious mononucleosis (Epstein-Barr virus) testing, monospot/heterophile antibody tests, or any glandular fever-specific screening test; no other ICHI section contains a sufficiently close match.
172727008 (Graft to eustachian tube)(not mapped)ICHI contains only five eustachian tube procedure codes (drainage, injection, catheter insertion, dilatation, and a target-only entry), none of which represents a graft or reconstruction of the eustachian tube; no adequate mapping exists within the current ICHI classification.
168456004 (Gross pathology request)(not mapped)A "gross pathology request" is an administrative/ordering act, not a health intervention performed on a patient. ICHI's histopathology code covers microscopic examination and does not match macroscopic gross pathology review or the administrative request concept.
737375007 (Group counseling)(not mapped)ICHI has no category code for counselling as a standalone, body-system-agnostic group intervention; all counselling codes (action PP) are tied to a specific body function target.
386460002 (Group education)(not mapped)ICHI education codes (action PM) are all body-function-specific, with no generic target-unspecified education category. The XG4M55 group recipient extension cannot form an assignable code on its own.
183459001 (Gynecological emergency hospital admission)(not mapped)ICHI does not classify hospital admissions or care-setting encounters — it codes the health intervention performed, not the administrative act of admission.
787379002 (Handling of oriented specimen)(not mapped)ICHI contains specimen collection codes but no codes covering laboratory specimen handling, orientation, or processing activities; this post-collection laboratory workflow step is outside the scope of assignable ICHI categories.
53958007 (Harvesting of donor material)(not mapped)This SNOMED concept is a high-level non-specific category describing procurement of any donor material without specifying the tissue type or site; ICHI procurement codes are all site- or tissue-specific.
183470008 (Hematology emergency hospital admission)(not mapped)ICHI does not classify administrative/organisational acts such as hospital admissions; it covers clinical interventions on body systems, functions, behaviours, or environments, with no code for emergency admission, specialty-specific admission, or inpatient encounter.
394981005 (HEp-2 cell autoantibody screening test)(not mapped)ICHI does not contain codes for ANA or autoantibody immunofluorescence screening tests using HEp-2 cell substrates; the essential laboratory test block (BlockL1-XG1) covers only specific WHO priority tests and does not include autoantibody panels.
225064000 (Heparinizing cannula)(not mapped)"Heparinizing cannula" refers to flushing a cannula with heparin to maintain patency, a nursing maintenance task rather than a discrete classified intervention; ICHI has no codes for heparin flushing or cannula maintenance, and the only cannulation code (DFP.JB.AF) is specific to the thoracic duct.
243768003 (Hepatic vein sampling catheter procedure)(not mapped)No specific ICHI code exists for hepatic vein blood sampling via catheter; the abdominal/pelvic vein block (BlockL5-IED) covers imaging and structural interventions on abdominal veins but not selective venous blood sampling, and the hepatic vein appears only as an extension/anatomy code without a dedicated procedural sampling category.
438629002 (High dose rate electronic brachytherapy)(not mapped)ICHI has no code for brachytherapy as a distinct modality — its radiotherapy codes are organised by anatomical target with action GA (destruction by radiotherapy) and do not distinguish delivery technique (external beam vs brachytherapy, HDR vs LDR vs electronic).
774001008 (High intensity focused ultrasound ablation)(not mapped)ICHI ablation codes exist only for cardiac conduction (HFC.GA.AF), pulmonary vein (HIE.GA.AA), and endometrium (NME.GA.AD); the means axis has no HIFU-specific instrument code, and no body-site-agnostic HIFU procedure code exists.
185468001 (Home visit for chronic condition)(not mapped)This SNOMED concept is an administrative encounter type representing a home visit for any chronic condition, with no specific clinical procedure or intervention; ICHI encodes specific health interventions and has no equivalent generic chronic disease home visit code.
185460008 (Home visit request by patient)(not mapped)This SNOMED concept describes an administrative act — a patient-initiated request for a home visit — rather than a clinical intervention; ICHI classifies health interventions and has no code for a service request or scheduling act.
391191004 (Homeless mental health care - Full day : day care)(not mapped)ICHI does not have codes representing care delivery settings, intensity levels (full-day vs part-day), or population-specific service configurations such as homeless mental health day care; no ICHI category adequately captures this concept.
391192006 (Homeless mental health care - Part day : day care)(not mapped)Like 391191004, this describes a care delivery modality (part-day mental health day care for homeless persons) rather than a specific clinical action; ICHI has no codes for service intensity or population-targeted delivery formats.
400979004 (Homeopathic consultation)(not mapped)ICHI does not include codes for homeopathy, naturopathy, or other complementary/alternative medicine consultations; nearest candidates (generic assessment codes) would misrepresent the homeopathic context.
165161007 (Diagnostic dye - subcutaneous)(not mapped)No ICHI code exists for subcutaneous administration of diagnostic dye (e.g., patent blue for lymphatic mapping or sentinel node identification). ICHI lacks a dedicated category for this procedure, and no sufficiently close code was found across injection, tracer, contrast, or skin-test searches.
287529009 (Diagnostic puncture and aspiration)(not mapped)ICHI has site-specific aspiration codes (e.g., percutaneous aspiration of prostate, aspiration of thyroid) and site-specific puncture codes (e.g., lumbar puncture, cranial puncture), but no generic cross-site "diagnostic puncture and aspiration" category. The SNOMED concept is a grouper for a family of procedures, and no single ICHI code adequately captures this non-site-specific grouper.
117338000 (Differential light absorption chemical test method)(not mapped)Differential light absorption (spectrophotometry) is a laboratory analytical technique/methodology. ICHI contains no codes for spectrophotometry, colorimetry, photometry, or chemical analysis methods, as these are test method descriptors rather than health interventions assignable in ICHI's classification scope.
62057008 (Dilation and stretching)(not mapped)"Dilation and stretching" is a generic, site-unspecified SNOMED procedure category with no anatomical qualifier; ICHI is organised by body target and does not have a generic cross-organ dilation/stretching code that would meaningfully represent this concept. No reasonable ICHI match exists without a specified anatomical target.
363081006 (Dilation of duct)(not mapped)ICHI only contains dilatation codes for specific named ducts (salivary, pancreatic, bile, frontonasal); there is no unspecified or generic "duct dilatation" code or block. The SNOMED concept is intentionally site-unspecified, making any specific duct code too narrow to map to.
363083009 (Dilation of genitourinary system)(not mapped)ICHI encodes genitourinary dilatation only at specific organ level (urethra NAM.LG.AA, ureter NAE.LG.AD, bladder neck NAK.LG.AA, vagina NMH.LG.AC, cervix NMF.LG.AC, fallopian tube NMC.LG.AA) with no unspecified or system-wide GU dilatation code. The SNOMED concept is intentionally generic across the entire genitourinary system, and no block-level dilatation code exists.
12558009 (Dilation of intestinal stoma)(not mapped)ICHI contains no code for dilatation of an intestinal stoma (ostomy); the nearest codes are dilatation of anal sphincter (KBX.LG.AC) or endoscopic dilatation of intestine NEC (KZZ.LG.AD), neither of which captures the specific clinical act of mechanically widening a surgically created intestinal stoma opening.
66851007 (Dilation of nares)(not mapped)ICHI has no dilatation code for the nares or nostrils. The nose block (BlockL5-JAA) contains codes for incision, excision, adhesion release, and reconstruction of the nose, but no dilatation action is coded for this target.
363085002 (Dilation of respiratory tract)(not mapped)ICHI provides dilatation codes for specific respiratory tract structures (larynx, trachea, bronchus) but has no code or block covering the respiratory tract as a whole. The SNOMED concept is a high-level category without a corresponding ICHI aggregate code.
81009007 (Dilation of sphenoid ostia)(not mapped)No dilatation code exists in ICHI for the sphenoid sinus or its ostia. The sphenoid sinus block (BlockL5-JAI) includes only biopsy, specimen collection, sphenoidotomy (incision), local excision, and sphenoidectomy — no dilatation action is represented for this target.
310426008 (Hormone replacement monitoring invitation)(not mapped)ICHI contains no code for sending a monitoring invitation or recall letter related to hormone replacement therapy; this concept describes an administrative/outreach act that falls outside ICHI's coded intervention space, and no reasonably close category exists.
228652008 (Horticultural therapy)(not mapped)Horticultural therapy does not appear in ICHI's coded categories; the classification includes art therapy and music therapy as extension codes only, and the closest activity domain codes (e.g., engaging in recreation and leisure) are too generic to constitute a meaningful match.
73607007 (Hospital admission, emergency, from emergency room)(not mapped)ICHI does not include administrative encounter types such as hospital admission or registration events — these are workflow/administrative acts outside ICHI's scope of health interventions. No code for "emergency admission" or equivalent exists anywhere in the classification.
18083007 (Hospital admission, emergency, indirect)(not mapped)This is an administrative encounter-type concept (an indirect/referred emergency admission) that ICHI does not classify; ICHI covers clinical and public health interventions, not administrative admission pathways or patient flow events.
310427004 (Hypertension monitoring invitation)(not mapped)This SNOMED concept represents an administrative/organisational act — inviting a patient to attend hypertension monitoring — which falls entirely outside ICHI's scope of clinical interventions, rehabilitation, and public health actions. No ICHI code covers patient recall or appointment invitation activities.
386327001 (Hypervolemia management)(not mapped)ICHI contains no code for fluid overload or hypervolemia management; searches across fluid management, volume, diuresis, oedema, and cardiovascular management yielded no relevant assignable category that captures the clinical concept of managing excess circulating volume.
414440000 (Hypothyroidism monitoring invitation)(not mapped)This SNOMED concept describes an administrative act — sending a monitoring invitation to a patient with hypothyroidism — which falls outside ICHI's scope of health interventions. No ICHI code covers patient recall or monitoring invitation letters.
363679005 (Imaging)(not mapped)The SNOMED concept "Imaging" is a high-level procedural category encompassing all imaging modalities across all body parts, with no equivalent top-level ICHI classification code; the ICHI action axis code "BA" (Imaging) is an axis component, not an assignable intervention code, and no single assignable ICHI category represents imaging in general.
277590007 (Imaging guided biopsy)(not mapped)ICHI does not have a site-unspecified "imaging guided biopsy" code — biopsy codes are always anchored to a specific body target. Because the SNOMED concept is deliberately site-agnostic and represents a broad procedure category, no single ICHI category code can represent it.
363143003 (Immune system destructive procedure)(not mapped)ICHI has no code representing destruction targeted generically at the immune system as a whole; destruction codes in ICHI are always organ-specific (e.g., lymph node, spleen, thymus) and no residual or NEC code in the haematopoietic/lymphatic chapter captures a generic "immune system destructive procedure" category.
363146006 (Immune system excision)(not mapped)ICHI has no generic "immune system excision" code; all excision codes are organ-specific (e.g., total excision of lymph node DFA.JK.AA, thymectomy DBA.JK.AB, splenectomy), and no residual category in the haematopoietic/lymphatic chapter covers excision of the immune system as an undifferentiated concept.
363147002 (Immune system incision)(not mapped)Like excision, ICHI encodes incision only at specific organ level (e.g., DBA.FA.AA incision of thymus, DJA.FA.AA incision of spleen) and there is no NEC or residual category representing incision of the immune system in general.
363151000 (Immune system repair)(not mapped)ICHI has no code representing repair or restoration of the immune system as a concept; the closest structural area (DTB — Immunological system function) covers assessment, administration of agents, and training, but none of its children describe a "repair" action on the immune system. This SNOMED concept is a high-level category without a corresponding ICHI assignable code.
414468001 (Immunosorbent method)(not mapped)ICHI has no code representing an immunosorbent technique (e.g., ELISA methodology) as a procedure type; the classification does not represent laboratory analytical methods at this level of specificity, and no related code in the DTB or XG blocks captures this concept.
1255694000 (Implantable venous access port injection)(not mapped)ICHI contains no code for injection through an implantable venous access port; codes for device insertion into thoracic or upper-limb veins describe port placement, not a subsequent injection through the port, and no intravenous administration code captures this specific route. The concept sits outside ICHI's current scope at this level of specificity.
112950009 (Implantation of nerve end into muscle)(not mapped)No ICHI code captures the specific procedure of burying a severed peripheral nerve end into adjacent muscle (a technique for treating neuromas). The closest candidates describe fundamentally different surgical manoeuvres and would misrepresent the intent of the SNOMED concept.
782902008 (Implantation procedure)(not mapped)This SNOMED concept is a high-level category representing any implantation procedure without specifying a target body part or device type; ICHI has no equivalent top-level generic "implantation" grouping code that is assignable, and assigning a specific body-system code would introduce unwarranted specificity.
372066005 (Implementation of protective measures during neurosurgical procedures)(not mapped)ICHI does not contain codes representing intraoperative safety or protective protocols specific to neurosurgery; the classification covers discrete clinical interventions rather than procedural safeguard activities, and no reasonably close match exists across any ICHI section.
372036003 (Implementation of protective measures prior to operative or invasive procedure)(not mapped)ICHI does not cover preoperative safety or protective-measure protocols as assignable intervention codes; extensive searching across prevention, infection control, perioperative, and precautionary terminology returned no suitable match for this pre-procedural administrative/safety activity.
185493004 (In-house physio - domiciliary visit)(not mapped)This SNOMED concept encodes an organisational/service-delivery fact — physiotherapy delivered in the patient's home by an in-house team — rather than a specific clinical intervention. ICHI classifies what is done, not where or by whom; "domiciliary" setting is not represented in ICHI at all.
185494005 (In-house ultrasound)(not mapped)This is a service-delivery descriptor (ultrasound performed in-house rather than referred externally), not a defined procedure with a body-part target. ICHI requires a specific body-part target axis; a body-agnostic "in-house ultrasound" has no corresponding ICHI code.
313183009 (Inappropriate use of out of hours service)(not mapped)This is an administrative/governance classification of a patient attendance event, not a health intervention performed on a patient. ICHI covers clinical procedures, rehabilitation, and public health actions; it has no domain for documenting inappropriate service use or demand management.
386332000 (Incident reporting)(not mapped)Incident reporting is an organisational quality and safety activity, not a health intervention directed at a patient. ICHI does not include administrative or governance processes, so there is no applicable code in the classification.
385343000 (Incision of cyst)(not mapped)ICHI does not have a generic body-site-unspecified "incision of cyst" code; cyst-related incision codes in ICHI are always site-specific (e.g., bladder cystotomy, bone cyst drainage), and no NEC/NOS residual category for incision of cyst across any anatomical region exists.
201749007 (Incision of ligament)(not mapped)ICHI only provides site-specific ligament incision codes (hand/finger, lower leg, foot/toe) with no generic body-site-unspecified "incision of ligament" category, and the other ligament blocks (shoulder, elbow, wrist, knee, hip) do not include an incision code at all.
107995004 (Incision of lymphatic system structure)(not mapped)The ICHI lymphatic system section contains drainage, biopsy, excision, and assessment codes but no incision code for a generic or unspecified lymphatic structure; site-specific lymph node blocks similarly lack a general incision entry.
40961004 (Incision of lymphoid tissue)(not mapped)ICHI has incision codes for individual lymphoid organs (tonsil DAA.FA.AC, spleen DJA.FA.AA, thymus DBA.FA.AA) but no single code representing incision of lymphoid tissue generically across all such structures; assigning any one organ-specific code would impose an anatomical specificity not present in the SNOMED concept.
61381007 (Incision of neck)(not mapped)ICHI does not have a generic "incision of the neck" category; neck interventions are organized by specific tissue type (artery, vein, muscle, skin/subcutaneous tissue, vertebral column), and none of these site-specific codes captures the undifferentiated anatomical region concept that the SNOMED term represents.
270431009 (Incoming mail processing)(not mapped)This SNOMED concept describes an administrative or occupational task (handling incoming mail) that has no clinical intervention counterpart in ICHI; ICHI's scope covers health interventions on body systems, functions, activities, and health-related behaviours, none of which correspond to mail processing.
441300002 (Increase temperature of infant incubator)(not mapped)This SNOMED concept describes adjusting the settings of a medical device (an infant incubator), which is a device-management task rather than a direct intervention on a patient's body or function; ICHI has no code for incubator temperature adjustment.
385879000 (Individual safety management)(not mapped)ICHI has no assignable category code for individual-level safety management as a clinical activity; the closest structural match is the block "Interventions on safety-related behaviours" (VC1), but a block code is not directly assignable, and the scope and framing differ (ICHI focuses on behaviour change; SNOMED's concept is a patient-level care management activity).
385819005 (Infection control assessment)(not mapped)ICHI contains numerous infection control intervention codes (VE action axis) and an assessment action axis (AA), but no code combining assessment with infection control exists; closest candidates are too semantically distant to constitute even a relatedto match for a clinical infection control assessment.
398258005 (Inflatable tourniquet positioned uninflated on patient)(not mapped)ICHI has no concept representing the application or positioning of a tourniquet on a patient; this is a pre-procedural preparatory step (placing an uninflated device on a limb), which falls outside the scope of any ICHI assignable category. Broad searches for "tourniquet," "bandage," "compression," "blood flow restriction," and positioning/device-placement terms all returned no relevant match.
119268003 (Inflation)(not mapped)"Inflation" as a stand-alone generic procedural concept (i.e., inflating a device or structure) does not correspond to any ICHI category; ICHI codes are body-system-specific and require a target, action, and means. Searches for "inflation," "dilation," "distension," and "occlusion" produced no generic match, and the concept is far too underspecified for any single ICHI code.
229222001 (Informal warm-up for therapy)(not mapped)ICHI contains no concept for a warm-up activity as a preparatory phase before therapy; its rehabilitation codes describe specific interventions on body functions rather than general preparatory warm-up activities. No search across exercise, movement, training, physiotherapy, therapy preparation, or rehabilitation terms returned a suitable match.
1184584003 (Information gathering from automated entry)(not mapped)ICHI has no concept for data collection distinguished by entry modality (automated vs manual); it classifies what is done to/for a person, not how clinical data is captured into a system. No ICHI code captures this administrative/informatics process even approximately.
1184585002 (Information gathering from manual entry)(not mapped)As with automated entry, ICHI does not model data-entry workflows or information-gathering distinguished by input method; this is a process of clinical documentation systems rather than a health intervention on a person, and no ICHI code exists for it.
223459007 (Informing of accident)(not mapped)ICHI has no code for notifying or informing parties about an accident; this is an administrative/safety reporting act that falls entirely outside ICHI's scope of health interventions. No action axis for "notification/disclosure" exists, and no appropriate target axis covers accident reporting.
223460002 (Informing of incident)(not mapped)As with informing of accident, notifying about a clinical or safety incident is an administrative act with no corresponding ICHI code; ICHI contains no "informing" or "incident reporting" action, and the concept sits outside the classification's scope of health interventions.
304563002 (Informing relative)(not mapped)ICHI does not contain a code for notifying or informing a relative/family member about a patient's condition; the closest ICHI constructs (counselling or advising about family relationships, support from immediate family blocks) all target a different clinical activity — supporting the patient in family engagement rather than the act of communicating clinical information to a third party.
169213004 (Infrared photography)(not mapped)ICHI contains only one photography code (BCC.BA.BL, fundus photography of the retina) and no general or infrared photography code; infrared photography as a diagnostic imaging technique of unspecified anatomy has no counterpart in ICHI's classification at any level of specificity.
439251009 (Initiation of therapeutic relationship)(not mapped)ICHI has no code representing the establishment or initiation of a therapeutic relationship as a distinct clinical act; the closest candidates (counselling, psychotherapy, interpersonal relationship intervention codes) all describe ongoing therapeutic actions targeted at specific functions or behaviours rather than the act of formally initiating a provider-patient therapeutic alliance.
59108006 (Injection)(not mapped)"Injection" in SNOMED is a high-level generic concept covering any injection procedure regardless of substance or site. ICHI structures injections by specific target anatomy and substance, with no overarching generic injection code that could reasonably represent this breadth.
23799006 (Injection of contrast media for radiography by catheter, non-selective)(not mapped)ICHI has only vessel-specific angiography codes (e.g., aortography, coronary angiography) and lacks a generic non-selective catheter contrast injection for radiography that spans multiple or unspecified vascular territories; no single assignable ICHI category code adequately represents this procedure.
836429007 (Injection of radioactive implant into malignant neoplasm for brachytherapy)(not mapped)"Brachytherapy seeds" appears only as an ICHI extension code (no standalone assignable category code), and there is no generic target-unspecified code for interstitial radioactive implantation into a tumour; all body-site radiotherapy destruction codes (GA.BA) are site-specific and do not capture the implant-insertion nature of brachytherapy.
432871008 (Insertion of drain using fluoroscopic guidance)(not mapped)ICHI encodes drainage anchored to a specific body-site target; there is no body-site-independent "drain insertion" code, and ICHI does not capture fluoroscopic guidance as a modifier on drainage actions (fluoroscopy appears only under imaging action codes). With no target site specified in the SNOMED concept, no assignable ICHI category is a reasonable match.
432273003 (Insertion of drain using ultrasound guidance)(not mapped)For the same structural reason as the fluoroscopic variant, ICHI has no site-agnostic drain insertion code and does not encode ultrasound guidance as a Means modifier on drainage actions. All ICHI drainage codes require a specific anatomical target that is absent from this concept.
179005009 (Insertion of drainage system into bone)(not mapped)ICHI has no drainage-of-bone category code at any site specificity level; bone drainage codes found (MLB.JB.AE, MNB.JB.AA) are limited to bone cysts at specific sites and do not represent general drainage system insertion. The closest structural candidate, MRB.DN.AA (Implantation of device into bone of unspecified site), represents device implantation rather than drainage, making it semantically too distant.
443263006 (Insertion of insulin pump)(not mapped)ICHI contains "Implantable insulin infusion pump" only as a blank-coded extension/modifier entry (not an assignable category code), and no assignable procedure code for inserting an insulin pump exists in the classification. The endocrine pancreas block (EBD) contains only islet cell procurement and transplantation, with no device insertion codes.
782901001 (Insertion procedure)(not mapped)This is a high-level SNOMED grouper concept covering all types of insertion procedures without specifying a target body structure or device; ICHI has no analogous top-level assignable category for unspecified insertion.
418488007 (Inservice)(not mapped)"Inservice" refers to continuing professional development or in-service education for healthcare workers, which falls outside the scope of ICHI's clinical and public health intervention categories; ICHI training codes are rehabilitation-oriented and patient-directed.
232819002 (Inspection of implanted aortic valve)(not mapped)ICHI contains no "inspection" or "assessment" action code for any cardiac valve target; the aortic valve block covers only therapeutic interventions (replacement, repair, dilatation, implantation), so no suitable approximation exists.
232881009 (Inspection of implanted atrioventricular valve)(not mapped)ICHI's only atrioventricular valve block (BlockL5-HDM) is scoped to congenitally malformed valves and contains only therapeutic procedure codes; there is no inspection/assessment concept for an implanted atrioventricular valve in ICHI.
232742000 (Inspection of implanted mitral valve)(not mapped)The mitral valve block in ICHI covers only therapeutic interventions; ICHI contains no inspection, assessment, or surveillance concept for an implanted prosthetic mitral valve.
232856006 (Inspection of implanted pulmonary valve)(not mapped)The pulmonary valve block in ICHI contains only therapeutic procedure codes with no corresponding inspection or assessment action; this SNOMED concept cannot be mapped.
232780004 (Inspection of implanted tricuspid valve)(not mapped)The tricuspid valve block in ICHI covers only therapeutic interventions; ICHI has no inspection, assessment, or surveillance concept for an implanted prosthetic tricuspid valve.
274437000 (Insufflation to evacuate)(not mapped)ICHI does not contain a code for insufflation as a means of evacuating contents; the SNOMED concept describes a procedural technique category (blowing gas into a space to displace contents) that has no assignable counterpart in ICHI.
1156382005 (Intensity modulated intracavitary brachytherapy)(not mapped)ICHI contains only "Brachytherapy seeds" as a supplementary/extension entry with no standard assignable category code, and no codes exist for intracavitary or intensity-modulated brachytherapy as a technique.
410298003 (Interaction education, guidance, and counseling)(not mapped)This is a high-level SNOMED grouper for clinical encounter types involving patient education, guidance, and counselling without specifying a body system or target; ICHI structures education (PM), advising (PN), and counselling (PP) actions against specific body functions, with no single ICHI category for this undifferentiated grouper.
22821003 (Intermittent mechanical traction)(not mapped)ICHI contains no traction codes whatsoever — the musculoskeletal blocks cover surgical and immobilisation interventions on spine and joints but not mechanical traction as a physical modality.
243203006 (Intermittent pneumatic calf-thigh compression)(not mapped)ICHI has no code for pneumatic compression therapy; the circulatory and lower limb intervention blocks cover surgical vascular procedures, with no assignable category code for intermittent pneumatic compression as a clinical intervention.
118476008 (Interposition arthroplasty)(not mapped)ICHI contains no arthroplasty or interposition joint procedure codes, and no site-unspecified joint reconstruction category exists; the available joint codes are either site-specific or limited to repair/implantation actions that do not capture the interposition technique concept.
422865007 (Interpreter/translator services education, guidance, counseling)(not mapped)ICHI contains no code representing individual-level clinical education, guidance, or counseling specifically about interpreter or translator services; the nearest environmental blocks (UEG communication services, UEP health services) are population/policy-level interventions and are semantically too distant to constitute a reasonable mapping.
24878005 (Intersex surgery)(not mapped)"Intersex surgery" is a high-level umbrella covering a heterogeneous set of genital and gonadal surgical procedures; ICHI has no single code or even a combined block that spans the full intersex surgical scope.
1127003 (Interstitial radium application)(not mapped)ICHI's radiotherapy destruction codes are all site-specific (e.g., AAA.GA.BA for brain), but this SNOMED concept specifies no target tissue, only the modality (interstitial radium); no site-unspecified interstitial radiotherapy application code exists in ICHI.
303577009 (Interventional debulking surgery)(not mapped)ICHI has no code for "debulking" or cytoreductive surgery as a concept — the classification organises procedures by anatomical target and action, and debulking is a surgical strategy applied across multiple targets rather than a distinct intervention type.
448168006 (Intracavitary brachytherapy of nasopharynx)(not mapped)ICHI's nasopharynx block (BlockL5-JAM) contains only surgical, imaging, and airway codes with no destruction or radiotherapy entry, and there is no generic destruction-of-nasopharynx code in the classification.
169362001 (Intracavitary brachytherapy using seed)(not mapped)"Brachytherapy seeds" appears in ICHI as an extension/means qualifier without an assignable category code, and there is no generic intracavitary brachytherapy procedure category in ICHI to anchor a mapping.
47668009 (Intracavitary radium application)(not mapped)ICHI does not contain an assignable code for intracavitary brachytherapy or radium application; the radiotherapy-coded categories in ICHI are organ-specific destruction codes that do not represent a general intracavitary radium procedure.
22480005 (Intracranial microdissection)(not mapped)ICHI has no code or concept for microdissection (a surgical technique qualifier) as a standalone intracranial procedure; the classification does not encode operative technique/instrumentation of this type as a distinct category.
384691004 (Intraluminal brachytherapy)(not mapped)ICHI contains "Brachytherapy seeds" only as an extension/means code (not an assignable category code), and has no dedicated assignable category code for intraluminal brachytherapy as a procedure.
386474009 (Intraoperative temperature regulation)(not mapped)ICHI has separate codes for warming (PZA.SD.BQ) and cooling (PZA.SE.ZZ) of central body temperature but no single code representing temperature regulation as a combined or unspecified intraoperative thermal management intervention; assigning either alone would misrepresent the directionally neutral SNOMED concept.
233595007 (Intravenous gas exchange)(not mapped)Intravenous gas exchange refers to an intravascular oxygenator device (such as IVOX) placed inside a large vein to perform gas exchange — a highly specific and rare intervention with no corresponding ICHI code; no code in ICHI captures both the intravenous route and the gas exchange function together.
118961005 (Introduction to urinary tract)(not mapped)This SNOMED concept is a high-level grouper representing any introduction into the urinary tract (unspecified substance, device, or target structure within the tract); no single ICHI assignable category represents this level of abstraction, and assigning a specific code such as bladder or urethra device insertion would incorrectly narrow the concept's scope.
780816009 (Invitation to participate in research study)(not mapped)ICHI does not cover research recruitment or invitations to participate in studies as a health intervention category. No block, behaviour, or administrative action in ICHI corresponds to this concept, which falls outside ICHI's classification scope.
135847007 (Involuntary admission)(not mapped)ICHI contains no code for compulsory or involuntary psychiatric or hospital admission. The classification's health-service and legal-service blocks (UEP, UEJ) deal with systems and policies rather than individual-level administrative or legal acts such as detention under mental health legislation.
67889009 (Irrigation)(not mapped)"Irrigation" as a standalone SNOMED concept is a highly generic procedure not tied to any specific body site; ICHI organises irrigation codes strictly by anatomical target (e.g., NAI.JA.AC for urinary bladder, BBB.JA.AH for cornea), and there is no site-unspecified parent irrigation code that could serve as a valid single mapping.
56377008 (Laboratory ratio determination)(not mapped)ICHI's Essential Laboratory Tests block covers specific named tests but does not have a generic code for the procedural act of computing a ratio from laboratory values; this analytic/mathematical step within laboratory medicine has no ICHI equivalent.
57501001 (Laboratory reporting, cum sum)(not mapped)Cumulative sum (CUSUM) reporting is a statistical quality-control technique applied within laboratory medicine to detect systematic errors over time; ICHI contains no code for laboratory reporting methods or statistical QC processes, making this unmappable.
33526004 (Laboratory reporting, electronic)(not mapped)This concept describes the administrative act of transmitting a laboratory report via electronic means, a health information management activity without any corresponding ICHI code. ICHI does not classify report delivery modalities or administrative communication acts of this nature.
5812006 (Laboratory reporting, fax)(not mapped)This concept describes laboratory report transmission by fax, a purely administrative/logistical act for which ICHI has no corresponding classification. ICHI focuses on health interventions, not on the communication channel used to convey report documents.
28491007 (Laboratory reporting, internal report)(not mapped)An internal report is an intra-facility administrative document routing act, not a health intervention on a patient or population. No ICHI code exists for this concept, as ICHI does not classify report formats or internal document workflows.
103764000 (Laboratory reporting, service comment)(not mapped)A service comment is an annotation or free-text addendum appended to a laboratory report — an administrative documentation act with no ICHI equivalent. ICHI contains no codes for report commentary or annotation activities.
45942001 (Laboratory reporting, telephone)(not mapped)This concept describes verbal communication of a laboratory result by telephone (e.g., critical value notification), which is an administrative communication act. ICHI has no codes for the modality of result delivery.
78068000 (Laboratory reporting, verbal)(not mapped)ICHI does not contain a concept for communicating laboratory results verbally; the classification covers laboratory test procedures and specimen collection but not the act of result reporting or notification.
87999009 (Laboratory reporting, written report)(not mapped)The act of issuing a written laboratory report is not represented in ICHI; ICHI covers the laboratory tests themselves (specimen collection, analyte testing) but not the downstream documentation and communication of results.
117347008 (Laboratory test method with analyte detection limit of 0.001mu/L)(not mapped)ICHI classifies laboratory interventions by the type of test performed and does not encode methodological characteristics such as analytical sensitivity or analyte detection limits; this SNOMED concept represents a test attribute rather than a classifiable intervention.
117348003 (Laboratory test method with analyte detection limit of 0.01 mu/L)(not mapped)ICHI has no axis or category for encoding the quantitative detection limit of a laboratory method; this concept characterises test performance, not the intervention itself.
117345000 (Laboratory test method with analyte detection limit of 20 mg/L)(not mapped)ICHI does not model analytical detection thresholds; this concept describes a methodological precision attribute that falls entirely outside ICHI's scope.
118184002 (Laboratory test with detection limit of <20mg/L)(not mapped)The SNOMED concept describes a methodological qualifier (analytical detection limit) applied to a laboratory test, not a specific test procedure itself; ICHI's Essential laboratory tests block lists named specific tests with no codes representing detection-limit-based test specifications.
309721001 (Laser removal of hair)(not mapped)ICHI contains no code for hair removal or epilation by any method; the only hair-related categories cover assessment of hair function, patient education about hair loss, and hair transplantation, none of which correspond to laser hair removal.
440195002 (Lavage of mammary duct and sampling of mammary cytologic material)(not mapped)ICHI has no code for mammary duct lavage or cytological sampling from the breast duct; the breast intervention block (LCA) covers biopsy, drainage, injection, and imaging but does not include ductal lavage with cytology collection as a distinct procedure.
413163007 (Learning disabilities health action plan reviewed)(not mapped)This is a UK-specific administrative act of reviewing a documented health action plan for a person with learning disabilities. ICHI contains no codes for plan review or care plan management activities.
386346000 (Learning facilitation)(not mapped)"Learning facilitation" is a general nursing intervention enabling patient learning without specifying a target domain; while ICHI has a block "Interventions on learning and applying knowledge", the codes within it are marked incomplete/unassigned, and no leaf-level category exists for generic facilitation of learning across domains.
414587005 (Left ventricular dysfunction monitoring invitation)(not mapped)ICHI has no concept corresponding to a monitoring "invitation" — a communication or administrative act to invite a patient into a monitoring programme. This is an administrative/recall action outside ICHI's scope.
270425006 (Letter from specialist)(not mapped)A "letter from specialist" is a clinical administrative document — a written communication artefact produced by a consultation — rather than a health intervention. ICHI contains no code for the production of specialist correspondence.
5357009 (Leukocyte poor blood preparation)(not mapped)Leukoreduction (removal of white cells from a blood product) is a specific blood-banking processing step that has no dedicated ICHI code; the only blood-block categories cover specimen collection, transfusion, therapeutic apheresis, and collection of blood products.
1351964001 (Life-sustaining treatment)(not mapped)ICHI does not contain a generic "life-sustaining treatment" category — it codes specific interventions such as mechanical ventilation or cardiopulmonary resuscitation individually. The SNOMED concept is an administrative/policy grouping that has no structural equivalent in ICHI's intervention taxonomy.
70751009 (Ligation)(not mapped)ICHI does not have a generic "ligation" code — all ligation codes in ICHI are target-specific (e.g., ligation of bronchus, ligation of kidney, ligation of spermatic cord). The SNOMED concept represents a bare procedure type without a specified target, for which no ICHI equivalent exists.
417586005 (Lissamine green B staining of eye)(not mapped)ICHI contains no code for ocular surface staining with vital dyes (lissamine green B, rose bengal, fluorescein for the anterior surface); the eye assessment codes do not encode dye-based surface staining as a procedure, and no suitable category exists.
123678003 (Lithotomy)(not mapped)ICHI has no generic "lithotomy" code; stone removal is represented by body-site-specific "Extraction of calculus" codes, none of which captures the unqualified, site-agnostic SNOMED concept. Assigning any single site-specific code would impose a specificity not present in the SNOMED term.
1156708005 (Low dose rate brachytherapy using temporary radioactive source)(not mapped)ICHI does not have an assignable code for brachytherapy as a treatment modality; "Brachytherapy seeds" and "Interstitial radioactive material" appear only as extension/supplementary codes, and there is no category code covering low dose rate or temporary-source brachytherapy as a therapeutic intervention.
440648002 (Low frequency noncontact and nonthermal ultrasound therapy)(not mapped)All ICHI ultrasound codes (BJ means axis) are diagnostic imaging procedures; ICHI has no code representing therapeutic/non-thermal ultrasound applied for wound care or other treatment purposes, and no relevant physical modality category exists for this intervention.
229565001 (Low power laser therapy)(not mapped)The only laser codes in ICHI (AAA.GA.AH and KCA.GA.AH) are for laser interstitial thermal therapy — a destructive, high-power surgical technique — which is the opposite of low-level/low-power laser therapy (photobiomodulation), a non-thermal rehabilitative modality with no corresponding ICHI category.
241735000 (Lower tourniquet cuff inflation)(not mapped)ICHI contains no concept corresponding to tourniquet application, cuff inflation, or pneumatic limb occlusion — this is an adjunctive technique used to create a bloodless surgical field rather than a standalone intervention coded in ICHI.
67022004 (Lymph gland thermography)(not mapped)ICHI contains no thermography or thermal/infrared imaging codes; lymph node imaging is represented only by lymphograms, ultrasound, and nuclear imaging modalities, none of which correspond to thermography.
287320009 (Lymph node graft)(not mapped)ICHI has no graft or transplantation code for lymph nodes themselves; the lymphatic system section only includes transplantation of lymphatic vessels (DFO.KD.AA) and excision procedures on lymph nodes, leaving lymph node grafting without a reasonable match.
445710004 (Lymphedema care)(not mapped)ICHI does not contain a code representing the holistic, multi-component care bundle for lymphedema (manual lymphatic drainage, compression therapy, exercise, and skin care); the closest individual codes each capture only one procedural component and none adequately represents "lymphedema care" as a concept.
47815000 (Lymphocyte storage)(not mapped)ICHI has no concept corresponding to lymphocyte storage or cryopreservation of lymphocytes — the haematopoietic/lymphatic and blood blocks cover collection and transfusion of blood products but not the preservation/storage of isolated lymphocytes.
58448000 (Lyophilized coagulation concentrate, reconstitution)(not mapped)Reconstitution of a lyophilized coagulation factor concentrate is a preparatory pharmaceutical step before administration; ICHI does not encode drug preparation or reconstitution activities, and no code in the blood interventions or haematological functions blocks captures this specific act.
372920002 (Maintaining confidentiality of patient information)(not mapped)ICHI classifies health interventions (clinical, rehabilitative, public health actions) and does not include administrative, ethical, or governance acts such as maintaining patient confidentiality; no relevant code or block was found.
710972007 (Maintaining fall safety alarm)(not mapped)ICHI contains extension codes for fall detectors as assistive products but no code for the nursing act of maintaining or activating a fall safety alarm device for a patient; the safety-related behaviour blocks (VC) cover population-level interventions, not bedside device management.
226003000 (Maintaining patient's safety)(not mapped)ICHI does not have a concept that captures the ongoing nursing/care activity of "maintaining patient safety" as a discrete intervention. The closest candidates are either population-level behaviour modification or a catch-all unspecified encounter, neither of which semantically represents direct clinical patient safety maintenance.
225348002 (Maintaining the client's dignity)(not mapped)ICHI does not have a code specifically representing maintaining a patient's dignity as a clinical intervention. The nearest candidates (SXK — enjoying human rights, PZB.TA.ZZ — advocating for a person) address related but distinctly different concepts.
133909001 (Maintenance of device)(not mapped)ICHI has no generic cross-body-system concept for device maintenance; all device management codes are organ- or system-specific (e.g., HFC.SN.AA for pacemakers, AAE.SN.AA for ventricular devices). The environment-section code UA1.SM.ZZ covers assistive/environmental technology rather than clinical implanted devices, and is semantically too distant.
26892002 (Making anesthesia bed)(not mapped)Making an anesthesia (post-operative recovery) bed is a nursing preparation activity that falls outside the scope of ICHI, which classifies health interventions applied to patients; no ICHI code exists for this logistical nursing task.
45553000 (Making circolectric bed)(not mapped)ICHI contains no codes for operating or preparing a circolectric (electrically rotating) hospital bed; the nearest candidate, PZA.LD.ZZ (Positioning of the whole body), describes actively repositioning the patient rather than setting up the bed mechanism, making the semantic gap too large for any mapping.
3936006 (Making Foster bed)(not mapped)A Foster bed is a manually rotating frame used for immobilised patients, and ICHI has no code representing bed preparation or frame operation; PZA.LD.ZZ (Positioning of the whole body) is conceptually adjacent but refers to patient repositioning as a clinical act, not to preparing or assembling a specialty bed.
1669000 (Making occupied bed)(not mapped)Making an occupied bed is a basic nursing/hygiene task (changing linen while the patient remains in the bed) that falls entirely outside ICHI's scope of codeable health interventions; no ICHI code addresses bedding management or this type of nursing activity.
228715004 (Making of bite block for radiotherapy)(not mapped)ICHI does not include codes for fabricating patient-specific radiotherapy accessories such as bite blocks (oral immobilisation devices used for head/neck positioning during treatment); the radiotherapy codes in ICHI cover tissue destruction (e.g., GAxx.BA) or population-level radiation interventions (UBR block), not device manufacture.
228716003 (Making of compensator for radiotherapy)(not mapped)A radiotherapy compensator is a beam-shaping device custom-fabricated to modulate dose distribution, and ICHI contains no codes for treatment device fabrication or radiotherapy planning equipment; as with the bite block, no ICHI category covers this technical/dosimetric activity.
45130007 (Making open bed)(not mapped)ICHI does not contain codes for hospital housekeeping or nursing bed-preparation tasks such as making an open bed; this is an operational/logistical nursing activity outside ICHI's scope of classifiable health interventions.
4424002 (Making orthopedic bed)(not mapped)No ICHI code exists for preparing or configuring an orthopedic bed; this is a supportive nursing/housekeeping task concerning patient environment setup, which falls outside the health interventions captured in ICHI.
78848005 (Making unoccupied bed)(not mapped)Preparing an unoccupied hospital bed is a basic housekeeping/nursing support task with no corresponding ICHI category; ICHI does not classify bed-making activities of this type.
713140006 (Management of dehydration)(not mapped)ICHI has no code representing management or treatment of dehydration as a clinical condition; searches for dehydration, rehydration, hydration, fluid replacement, and electrolyte therapy returned no relevant procedure-level match. The only water/electrolyte balance codes found (ETE.AA.ZZ, ETE.PM.ZZ) cover assessment and education only, not active management of the dehydrated state.
700104004 (Management of inflammatory bowel disease)(not mapped)ICHI does not contain a code or block corresponding to the management of inflammatory bowel disease as a disease-level management concept; the digestive system function codes (KT2 block) address specific physiological functions rather than disease management, and no IBD-specific intervention category exists in the classification.
396072003 (Management of Patient Bill of Rights policy)(not mapped)ICHI has no code addressing the development, implementation, or management of a Patient Bill of Rights or equivalent patient-rights policy instrument within a health service organisation; the "policy change" codes in ICHI (WJ action axis) are scoped to environmental or behavioural public health targets, not to internal health service governance or patient rights documentation.
710058001 (Management of vasopneumatic device)(not mapped)ICHI contains no code or block for vasopneumatic (intermittent pneumatic compression) devices; searches across device management, circulatory interventions, compression, lymphoedema, and assistive products returned no applicable match for this specific therapy.
405686007 (Manhandling procedure for physical restraint)(not mapped)ICHI contains no code for physical (manual/bodily) restraint of a patient by staff; the classification covers behaviour-related and environmental interventions but does not represent hands-on physical restraint as a clinical procedure, leaving this SNOMED concept without a reasonable ICHI match.
44678002 (Manipulation of mouth)(not mapped)ICHI contains no manipulation or mobilisation code targeting the mouth or oral cavity; the mouth/pharynx interventions block covers surgical and examination procedures but has no equivalent manual manipulation category. No assignable code provides even an approximate match.
49825002 (Manipulation of spinal cord)(not mapped)ICHI's spinal cord block (ABA) contains only surgical, imaging, and repair interventions on the spinal cord itself, and the vertebral column manipulation codes (e.g., MBZ.PA.AH) target the bony spine rather than the spinal cord as a neural structure. No ICHI code represents manipulation of the spinal cord as a target.
363196007 (Manipulation procedure by device)(not mapped)This SNOMED concept is a high-level hierarchy node for any procedure involving device-based manipulation, with no equivalent abstract grouping in ICHI; ICHI device-related codes are always anchored to a specific body target and no body-system-neutral "manipulation by device" category exists.
117044006 (Manual laboratory procedure)(not mapped)ICHI is a classification of health interventions performed on or for patients, not a classification of laboratory bench procedures; "manual laboratory procedure" is a generic technical/analytical process concept with no corresponding ICHI category or reasonable approximation in the classification.
112696003 (Manual reduction)(not mapped)"Manual reduction" in SNOMED is a high-level, non-specific concept encompassing reduction of fractures, dislocations, hernias, prolapses, and more across any body site; ICHI has many specific manual reduction codes (e.g., KBK.LD.AH for ileostomy prolapse, MBA.LD.AH for cervical spine, PAM.MK.AH for inguinal hernia) but no single overarching code that maps to this generic unspecified concept.
241736004 (Manual tourniquet application)(not mapped)ICHI contains no code for tourniquet application as a standalone intervention; extensive searches across haemostasis, compression, occlusion, fixation, external device application, and manipulation terms returned no matching concept.
225135006 (Marking skin site prior to procedure)(not mapped)ICHI does not include pre-procedural skin marking as a codeable intervention; searches across marking, skin assessment, surgical site preparation, and procedure preparation returned no relevant results.
302389000 (Marsupialization of skin lesion)(not mapped)ICHI organises skin interventions strictly by body region (head/neck, trunk, upper limb, lower limb) with no body-site-neutral skin category, so any candidate code would impose a site restriction absent from the SNOMED concept. Additionally, no ICHI code represents the marsupialization action on a skin lesion.
384811003 (Meals on wheels program management)(not mapped)ICHI has no concept for managing or administering a home-delivered meals program; the closest candidates address direct food provision or social service delivery to an individual, not the administrative/program-management function this SNOMED concept describes.
122869004 (Measurement)(not mapped)"Measurement" in SNOMED is an ultra-broad, abstract concept encompassing any quantification act across all body systems; ICHI has no single top-level code for generic measurement — every measurement code is anchored to a specific target.
363200002 (Mechanical stimulation)(not mapped)"Mechanical stimulation" is a very high-level, non-site-specific SNOMED concept with no equivalent in ICHI; ICHI stimulation codes are all target-specific and none captures a generic, body-site-unspecified mechanical stimulation intervention.
80970002 (Medical evaluation, quality of care, review of exception case)(not mapped)This SNOMED concept describes an administrative quality assurance activity (case exception review for quality-of-care monitoring), which is a health system governance function. ICHI classifies health interventions on patients, not internal clinical governance or administrative case review processes, so no appropriate ICHI code exists.
57537006 (Medical evaluation, utilization review)(not mapped)Utilization review is an administrative/managerial process of evaluating the appropriateness of health service use, not a direct health intervention on a patient. ICHI has no category for health system management or administrative review functions of this type.
312853008 (Medical records review)(not mapped)Medical records review is an administrative information management activity rather than a clinical intervention performed on a patient. Searches across ICHI for "records," "documentation," "information," and related terms returned no relevant categories, confirming this concept is outside ICHI's scope.
305212007 (Medical records transfer)(not mapped)Medical records transfer is an administrative health information management task involving moving patient documentation between parties or systems, not a clinical intervention on a patient. ICHI's "transfer" codes relate to anatomical tissue/organ transfers (e.g., tendon transfer), not document or data transfer, leaving this concept unmatched.
229057006 (Meetings)(not mapped)ICHI contains no concept representing a clinical or administrative meeting, conference, or care coordination activity — the classification focuses on health interventions performed on or for a patient rather than organisational activities. No synonym search (consultation, conference, multidisciplinary, case management, team, coordination) returned a relevant match.
391262005 (Mental health caregivers' respite healthcare resource groups)(not mapped)This SNOMED concept is an NHS administrative Healthcare Resource Group (HRG) — a funding/classification grouping for caregiver respite services, not a clinical intervention. ICHI classifies health interventions, not administrative resource groupings, and has no equivalent concept for HRG-level administrative categories.
391263000 (Mental health caregivers' support healthcare resource groups)(not mapped)Like 391262005, this is an NHS administrative Healthcare Resource Group for caregiver support services, not a clinical intervention description. ICHI contains no administrative grouping constructs, and while it has codes for practical and emotional support interventions, none represent the HRG administrative category concept itself.
391273003 (Mental health crisis resolution HRGs)(not mapped)This is an NHS administrative HRG grouping for mental health crisis resolution services, not a clinical procedure or intervention. ICHI has no crisis resolution or acute psychiatric intervention codes, and the administrative HRG framing has no equivalent in the ICHI classification structure.
391265007 (Mental health residential care HRGs)(not mapped)This SNOMED concept refers to Healthcare Resource Groups (HRGs) — an administrative NHS costing/classification construct for residential mental health care episodes — which is a classification artefact rather than a clinical intervention; ICHI classifies health interventions, not administrative grouping systems, so there is no appropriate ICHI mapping.
401289003 (Methicillin resistant Staphylococcus aureus screening test)(not mapped)ICHI does not contain a code for microbiological or organism-specific screening tests such as MRSA screening; the classification does not cover laboratory diagnostic tests at this level of specificity, and no related code in the infection control or surveillance sections matches the clinical intent of an individual patient MRSA screen.
252414008 (Methylene blue test)(not mapped)The methylene blue test is a specific diagnostic procedure used in multiple contexts (urinary tract fistula detection, sentinel node mapping, swallowing assessment with dye) but ICHI does not have a code for this test under any of these applications; the only dye-related test found (BAD.AC.AH, Dye disappearance test) is specifically an ophthalmic lacrimal drainage test and is not semantically equivalent.
19851009 (Microbiology procedure)(not mapped)ICHI does not contain a dedicated microbiology or microbiological testing category; the Essential Laboratory Tests extension block (BlockL1-XG1) covers only a narrow set of named tests (HIV, HCV, etc.) and does not represent the broad class "microbiology procedure." No sufficiently close ICHI code exists for this high-level procedural category.
47902005 (Microwave diathermy)(not mapped)ICHI contains no code specifically for microwave diathermy (a physical therapy modality using microwave energy for deep tissue heating); the hyperthermy codes present in ICHI (e.g., MRM.SD.BQ for muscle hyperthermy) are tied to specific anatomical targets and none generically represents the microwave diathermy modality as a standalone intervention.
1255636001 (Midwife consultation)(not mapped)ICHI does not contain a consultation or clinical encounter concept, nor any midwifery-specific code. The nearest area (interventions on functions related to pregnancy, block NUE) covers only specific functional assessments and training, not the broader encounter implied by a midwife consultation.
225156008 (Milking chest drain)(not mapped)Milking (stripping) a chest drain is a bedside nursing procedure to maintain tube patency by manually compressing the drain tubing. ICHI covers insertion, replacement, and removal of pleural drainage devices but has no code representing maintenance manipulation or patency management of an existing drain.
711580002 (Minor ambulatory surgery)(not mapped)ICHI classifies interventions by what is done (action, target, means) and does not have organisational or service-delivery concepts such as "ambulatory surgery" or procedural complexity tiers like "minor"; no ICHI code or block corresponds to this administrative/care-setting concept.
173868001 (Mobilization of duodenum)(not mapped)ICHI contains no code specifically for mobilization (freeing/detaching) of the duodenum; the duodenal block (KBI) includes incision, excision, reconstruction, and anastomosis but not a discrete mobilization procedure, and there is no ICHI action code that maps cleanly to surgical mobilization of this structure.
237000000 (Modification of uterine activity)(not mapped)ICHI does not contain a code representing modification of uterine activity as a broad concept (encompassing both induction/augmentation and suppression/tocolysis of uterine contractions); the closest codes are NME.SH.AC/AF (medical induction of labour) or NME.AI.AH (monitoring of delivery), but none captures the general concept of modifying uterine muscle activity.
711002000 (Monitoring fall risk)(not mapped)ICHI does not contain a code for monitoring or assessing fall risk specifically; searches across safety, fall, balance, gait, and mobility terms returned no code that captures fall risk surveillance as a distinct clinical activity, and the nearest structural candidates (MVG.AA.ZZ, SJA.AA.ZZ) address only individual components rather than fall risk as an integrated assessment.
710997006 (Monitoring for impaired family coping)(not mapped)ICHI has no monitoring code for family coping or stress responses; the closest candidates (SSJ family relationship codes, AS1 mental function monitoring, SDJ stress/psychological demand codes) are all assessment or intervention types rather than monitoring for impaired coping specifically, and none capture the nursing surveillance concept embedded in this SNOMED term.
442337006 (Monitoring of intraocular pressure during vitrectomy)(not mapped)ICHI contains vitrectomy (BCD.JK.AA) and various pressure measurement codes, but no code captures intraocular pressure monitoring specifically, nor does ICHI model intraoperative monitoring as a separate procedure distinguishable by the surgical context (during vitrectomy); this highly specific peri-operative surveillance concept has no reasonable ICHI equivalent.
427406007 (Monitoring of lochia by sanitary pad count)(not mapped)ICHI has no codes for postpartum or puerperal monitoring; despite thorough searching across female genital system, pregnancy-function, and uterus blocks, no code covers lochia assessment or postpartum bleeding surveillance, making this concept unmatched.
182777000 (Monitoring of patient)(not mapped)ICHI's "Monitoring" (action axis code AI) is a structural axis value rather than an assignable category, and all monitoring codes in ICHI are tied to a specific body system, function, or structure; there is no generic "monitoring of patient" category that captures this undifferentiated surveillance concept.
1254959003 (Monitoring substance withdrawal)(not mapped)ICHI contains interventions on illicit drug use behaviours (VAC block) and alcohol use behaviours (VAA block), but these concern population-level or behavioural interventions such as assessment, counselling, and prescription — not clinical monitoring of a patient's physiological withdrawal state; no ICHI code captures the bedside or clinical monitoring of substance withdrawal syndrome.
60374009 (Morphometric analysis)(not mapped)Morphometric analysis (quantitative measurement of anatomical or cellular structures, e.g., bone morphometry, cell size measurement in histology) has no corresponding ICHI code; ICHI does not classify laboratory analytic or measurement methodologies at this level of technical specificity, and no fuzzy or synonym searches yielded a meaningful candidate.
281176004 (Mounting of dental model on articulator)(not mapped)Mounting a dental model on an articulator is a dental laboratory/technical procedure used in prosthetics planning; ICHI does not contain codes for dental laboratory technical procedures of this type, and no code in the dental (KAE) block or elsewhere in ICHI covers this activity.
281177008 (Mounting of denture on articulator)(not mapped)Mounting a denture on an articulator is a dental technical/laboratory procedure for prosthetic fabrication and adjustment; this class of pre-clinical dental laboratory work is outside the scope of ICHI, which covers health interventions delivered to patients rather than bench-work on dental appliances.
119870003 (Mouth transposition)(not mapped)ICHI contains no transposition/transfer (LJ action axis) code for any oral cavity structure (KAA–KAZ blocks), and the fuzzy search yields only transplantation or transport codes from unrelated domains. No clinically reasonable ICHI equivalent exists for this concept.
440102005 (MRI guided ablation)(not mapped)ICHI has no generic body-site-independent ablation/destruction code; all destruction codes (GA action) are body-site-specific, and none of the existing site-specific ablation codes combine with the MRI guidance means (BH) in a way that matches this body-site-unspecified SNOMED concept. The SNOMED concept is itself a broad category rather than a specific procedure, and no ICHI code represents MRI-guided ablation in a site-nonspecific way.
301786007 (Multi-resistant staphylococcus aureus screening)(not mapped)ICHI contains no codes for MRSA-specific testing, bacterial screening, colonisation detection, or antimicrobial resistance organism identification beyond a tuberculosis DNA resistance test. The closest adjacent concepts (infection control measures, contact tracing) do not capture the laboratory screening action for MRSA carrier status.
870253002 (Myeloablative conditioning regimen)(not mapped)ICHI contains no code for a myeloablative or preparative conditioning regimen prior to stem cell transplantation. The closest haematopoietic system code (DGA.KD.AF, Bone marrow or stem cell transplant) describes the transplant procedure itself, not the preceding cytotoxic or radiation-based conditioning, making it semantically distinct.
277263004 (Nasal decrusting)(not mapped)ICHI has no code for nasal decrusting, nasal crust removal, or nasal debridement; JAA.JG.AC does not exist in the classification. The only candidates in the nose block (JAA.JA.AC Irrigation of nasal passages, JAA.GA.AC Destruction of intranasal lesion) describe different procedures with different mechanisms and clinical intent.
440460006 (Natural suppression of lactation)(not mapped)The ICHI lactation block (BlockL5-NUH) contains only four assignable codes: assessment, education, advising, and counselling about lactation — none of which represent a suppression or inhibition of lactation function. Natural (physiological) suppression of lactation has no corresponding ICHI intervention code.
119594008 (Neck destructive procedure)(not mapped)ICHI encodes neck destruction only at fine-grained tissue-specific levels (e.g., LAA.GA.AH for skin/subcutaneous tissue of head or neck, MBA.GA.AE for cervical spine lesion), none of which serves as a cross-tissue grouper for any neck destructive procedure. No single assignable ICHI code captures the broad category of neck destruction spanning all tissue types, and block codes are not assignable.
119599003 (Neck transposition)(not mapped)ICHI contains no neck-specific transposition codes; the only transposition codes near the neck region are for cranial nerve (AAN.LJ.AA) and parotid gland duct (KAM.LJ.AA), both of which are too anatomically narrow to represent a general neck transposition procedure. No reasonable ICHI match exists for this SNOMED grouper concept.
717246005 (Neurological system care)(not mapped)"Neurological system care" is a broad administrative/care-coordination concept denoting ongoing management of a neurological condition, not a discrete clinical intervention. ICHI contains no equivalent concept for specialty-level care management; the closest candidate (AZZ.AA.ZZ "Neurological assessment, not elsewhere classified") captures only a single assessment act and does not represent the full scope of ongoing care.
183467009 (Neurology emergency hospital admission)(not mapped)Hospital admission is an administrative/health-service event, not a clinical intervention on a body structure or function, and ICHI contains no code for inpatient admission or emergency admission in any specialty. No reasonable ICHI match exists.
183476002 (Neurosurgical emergency hospital admission)(not mapped)ICHI classifies health interventions (procedures, therapies, assessments) and does not include administrative/logistical concepts such as hospital admissions. There is no ICHI code corresponding to an emergency inpatient admission event, regardless of specialty.
310424006 (New patient screening invitation)(not mapped)ICHI does not contain any code for inviting or recalling a patient for screening; the closest concepts in the VDB block address education, awareness raising, or advocacy around screening behaviours, none of which represent an administrative screening invitation sent to an individual patient.
165119001 (Non-surgical biopsy - administration)(not mapped)The SNOMED concept is an administrative/procedural category for non-surgical biopsy in general (not site-specific), and ICHI has no corresponding generic non-surgical or percutaneous biopsy code that is site-independent; all ICHI biopsy codes require a specific anatomical target, making a meaningful single-code mapping impossible.
228591007 (Normalization therapy)(not mapped)"Normalization therapy" is a rehabilitation philosophy/approach focused on enabling people with disabilities to participate in ordinary social life, with no direct ICHI equivalent. ICHI has codes for specific activities and participation interventions but nothing capturing the overarching normalization therapy concept, and no residual rehabilitation category is close enough to constitute a reasonable match.
228116005 (Notification of adoption)(not mapped)"Notification of adoption" is a legal/administrative act of formally informing relevant parties or registries of an adoption event; ICHI does not contain codes for administrative notifications of social/legal life events, and no code in the legal services, social security, or health services blocks captures this concept specifically enough to constitute a reasonable match.
312486000 (Notification of birth)(not mapped)"Notification of birth" is an administrative act of formally registering or reporting a birth to health or civil registration authorities; ICHI has no codes for vital events registration or birth notification, and the available public health surveillance and health services blocks are far too broad to serve as a reasonable match.
450810001 (Notification of miscarriage)(not mapped)ICHI contains no concept for notifying or reporting a miscarriage; the pregnancy-related interventions in block NUE cover assessment, monitoring, and education of pregnancy functions, none of which correspond to a formal notification act about a completed spontaneous abortion. No communication, administrative, or obstetric codes come close enough to assign even a relatedto mapping.
22815002 (Nursing care quality assurance procedure)(not mapped)Quality assurance is an administrative/managerial meta-activity that evaluates the delivery of care rather than being a health intervention on a patient, body system, or health-related behavior; ICHI does not classify administrative quality management activities, so no reasonable ICHI code exists.
410138008 (Nursing status report education)(not mapped)The educational component embedded within a nursing status report has no ICHI equivalent; ICHI's education codes (action PM) are all tied to specific body functions or activity targets and none captures a generic, profession-specific "education within a status report" construct.
410350005 (Nutritionist case management)(not mapped)ICHI contains no code representing case management or care coordination as a distinct intervention type; the closest health-services codes (e.g., UEP.TD.ZZ "Collaboration relating to health services") cover organisational collaboration, not the clinical case management function performed by a nutritionist.
33317003 (Ober-Yount fasciotomy, combined with spica cast, pins in tibia and wedging the cast)(not mapped)The Ober-Yount fasciotomy targets the fascia lata/iliotibial band at the hip/thigh region, but ICHI has no ligament-or-fascia block for the hip or thigh; furthermore, this is a multi-component combined procedure (fasciotomy + spica cast + tibial pins + cast wedging) with no corresponding composite ICHI code.
310428009 (Obesity monitoring invitation)(not mapped)ICHI does not represent administrative scheduling acts such as invitations or recall letters for monitoring appointments; the classification covers clinical interventions and public health actions, not patient-contact/communication logistics of this type.
119271006 (Obliteration)(not mapped)All ICHI obliteration codes are site-specific (tympanomastoid cavity, mastoid, frontal sinus, calyceal diverticulum, vaginal vault) and there is no generic or unspecified obliteration code; without a specified anatomical target, no valid ICHI code can be assigned.
183460006 (Obstetric emergency hospital admission)(not mapped)ICHI does not classify care delivery pathways, service encounters, or hospital admissions — it classifies health interventions on targets. No ICHI code represents an emergency admission event; this concept describes a health service utilisation event outside ICHI's scope.
88291001 (Obstetric panel)(not mapped)An "obstetric panel" is a defined set of laboratory tests ordered together during pregnancy (e.g., blood type, rubella titre, hepatitis B, CBC), which falls outside ICHI's classification scope — ICHI does not model laboratory test panels or order sets.
108102005 (Obstetrics excision)(not mapped)"Obstetrics excision" is a high-level grouper concept with no direct ICHI equivalent — it could encompass hysterectomy, excision of ectopic pregnancy, umbilical cord excision, placenta removal, and other excisions performed in the obstetric context. No single ICHI category maps meaningfully without being either far too specific or far too broad.
414925007 (Obtaining consent)(not mapped)ICHI does not contain a code for obtaining or documenting informed consent, which is an administrative/legal process rather than a health intervention on a body system, function, or behaviour; exhaustive searching across clinical, administrative, documentation, education, and environmental sections returned no applicable code.
234728009 (Occlusal equilibration)(not mapped)ICHI does not contain any code for occlusal equilibration (selective grinding/reshaping of tooth surfaces to balance the bite); no dental reshaping, grinding, or bite adjustment code exists in the ICHI teeth block (KAE) or any other block.
702778004 (Offering of child and adolescent mental health service choice appointment)(not mapped)This SNOMED concept describes an administrative act (offering a service-choice appointment) within a specific patient group; ICHI does not have a code for scheduling or offering appointment choices, and none of the health-service environment codes or mental-function intervention codes come close.
179717003 (Open drilling of articular cartilage)(not mapped)ICHI has no code representing drilling of articular cartilage (a technique used for marrow stimulation/microfracture); the cartilage intervention codes available (repair, division, procurement, transplantation) do not capture the drilling/perforation action, and no action axis code for drilling exists in the ICHI cartilage hierarchy.
174450000 (Open insertion of cannula for perfusion of liver)(not mapped)ICHI contains no code for cannula insertion into the liver for perfusion purposes; the liver intervention block covers biopsy, imaging, excision, drainage, transplant, and extracorporeal hepatic assistance, but not the specific act of open cannulation to establish hepatic perfusion.
179708003 (Open operations on synovial membrane of joint)(not mapped)ICHI has no assignable code or dedicated block for interventions on the synovial membrane; there is no synovectomy or synovial membrane procedure category in the classification. The SNOMED concept is a high-level grouper with no single ICHI code that captures open operations on synovial membrane across any joint.
74607004 (Open reduction of closed hyoid fracture)(not mapped)The ICHI hyoid block contains only partial excision and suspension codes; no open reduction of hyoid fracture exists, and no other ICHI code covers bone fracture reduction in the hyoid region — the skull and facial bone open reduction codes do not extend to the hyoid.
302470004 (Operation on branchial cleft)(not mapped)ICHI contains XA60Q5 "Branchial cleft" only as a target extension code (not an assignable procedure code), and there is no dedicated procedure block or category for interventions on the branchial cleft.
657004 (Operation on bursa)(not mapped)ICHI contains XA16K5 "Bursa" only as a target extension code, and no dedicated procedure block or assignable category for interventions on the bursa exists anywhere in the ICHI musculoskeletal hierarchy.
1417002 (Operation on face)(not mapped)ICHI does not have a single "face" target or unspecified assignable code covering operations on the face as a whole; facial interventions are dispersed across many organ- and tissue-specific blocks (facial bone, soft tissue of head/neck, skin, etc.) with no unifying face-level code.
17045008 (Operation on fascia)(not mapped)ICHI organises fascia interventions by specific body region (shoulder, upper arm, forearm, hand, lower leg, foot) with no pan-body or unspecified fascia target code, so the general SNOMED concept of an operation on fascia cannot be mapped to any single ICHI code.
64915003 (Operation on heart)(not mapped)"Operation on heart" is a high-level grouping concept covering any surgical procedure on the heart; ICHI organises cardiac interventions across many distinct blocks (atrium, ventricle, valves, pericardium, coronary arteries, etc.) with no single block or code representing the entire heart as a surgical target.
175839000 (Operation on jugular body)(not mapped)The jugular body (glomus jugulare) is a paraganglionic chemoreceptor structure, and ICHI contains no intervention codes for this structure; the only ICHI reference is an extension anatomy code XA17K2 (Glomus jugulare), which is not an intervention code.
39380002 (Operation on neck and trunk)(not mapped)ICHI organises interventions by body system rather than by gross anatomical region; "neck and trunk" spans dozens of separate ICHI blocks across respiratory, circulatory, musculoskeletal, integumentary, and digestive system chapters with no single code or block that covers this combined anatomical region. The concept is too heterogeneous for a meaningful single ICHI mapping.
28614009 (Operation on periurethral tissue)(not mapped)ICHI has no dedicated target axis code for periurethral tissue (the connective/soft tissue surrounding the urethra); the urethra block (BlockL5-NAM) covers the urethra itself but not the surrounding tissue. No ICHI block or category corresponds closely enough to warrant even a relatedto mapping.
33616003 (Operative procedure on carotid body)(not mapped)The carotid body (glomus caroticum) is recognised in ICHI only as an extension code anatomy term (XA0F61), not as an intervention target with any associated procedure codes. No ICHI category or block exists for operative interventions on the carotid body, making a meaningful mapping impossible.
183464002 (Ophthalmological emergency hospital admission)(not mapped)ICHI classifies clinical health interventions and does not model administrative care-pathway events such as emergency hospital admission; no ICHI code represents the act of admitting a patient to hospital for an ophthalmological emergency.
121826005 (Optical density measurement)(not mapped)Optical density measurement is a laboratory spectrophotometric technique (e.g., measuring bilirubin absorbance or bacterial culture turbidity) for which ICHI contains no corresponding code, as this level of analytical detail is outside ICHI's scope.
183473005 (Oral surgical emergency hospital admission)(not mapped)ICHI classifies health interventions, not administrative or organisational events such as hospital admissions; no ICHI code exists for the act of admitting a patient to hospital for an oral surgical emergency.
386378008 (Order transcription)(not mapped)"Order transcription" is an administrative/clerical health information management act that falls outside ICHI's scope, which covers clinical, rehabilitative, and public health interventions. No ICHI code for documentation, transcription, or administrative order management exists.
183461005 (Orthopedic emergency hospital admission)(not mapped)ICHI does not classify hospital admissions or administrative care-pathway events — it encodes clinical interventions. No ICHI code covers the act of emergency inpatient admission even at a broad level.
185464004 (Out of hours visit - not night visit)(not mapped)ICHI classifies health interventions by clinical content, not by administrative or scheduling context; there is no ICHI code representing when or where a visit occurs.
185449004 (Outgoing mail processing)(not mapped)ICHI does not classify administrative or clerical healthcare activities such as mail processing; no mail, correspondence, or document management codes exist in ICHI.
773504003 (Ozone therapy)(not mapped)ICHI contains no code or block for ozone therapy; text search, fuzzy search, and browsing of complementary/physical therapy sections all returned no relevant results. Ozone therapy is not represented in the current ICHI classification.
235513003 (Palliative procedure for pancreatic pain relief)(not mapped)ICHI does not encode procedural intent (palliative) as a standalone classifier, nor does it have codes for nerve-block or neurolytic procedures targeting the coeliac/splanchnic plexus for pancreatic pain; no single ICHI code reasonably represents this heterogeneous SNOMED grouping concept.
225331005 (Participative approach)(not mapped)"Participative approach" is a care philosophy or methodology (involving the patient as an active participant in decision-making), not a discrete health intervention; ICHI classifies actions performed on or for a patient and contains no code representing a participative or shared-decision-making approach.
386384006 (Pass facilitation)(not mapped)"Pass facilitation" refers to the administrative process of helping a patient obtain a disability or travel pass — this is an administrative/social welfare action with no corresponding clinical health intervention in the ICHI classification. No fuzzy or synonym searches yielded a relevant match.
270830003 (Passport application)(not mapped)A passport application is a non-clinical administrative activity that falls entirely outside the scope of ICHI health interventions. Extensive searching including synonyms (travel document, administrative, certification) returned no relevant results.
270350005 (Passport application signing)(not mapped)Signing a passport application is a documentation/administrative act by a clinician on behalf of a patient — it is not a health intervention and has no representation in ICHI. No searches for signing, certification, or document-related terms returned relevant results.
116783008 (Pathologist evaluation)(not mapped)ICHI does not contain a code representing a pathologist's evaluation of clinical specimens or tissue; the classification covers procedural health interventions rather than the professional interpretive act of a pathologist reviewing a specimen, and no sufficiently close code was found across diagnostic, assessment, or laboratory blocks.
116784002 (Pathologist report)(not mapped)A "Pathologist report" is a documentation/reporting act performed by a pathologist on tissue specimens — it is a record-creation activity rather than a health intervention as ICHI defines them. ICHI does include XG30Q5 (Histopathology) as an extension code, but that denotes the analytical method, not the reporting act itself, and extension codes are not standalone assignable intervention codes.
184171009 (Patient deregistration)(not mapped)ICHI has no code for administratively removing a patient from a practice list or care register; this is a health-service administrative act (de-enrollment) with no equivalent in the ICHI classification.
1917008 (Patient discharge, deceased, medicolegal case)(not mapped)This SNOMED concept describes an administrative discharge disposition for a deceased patient whose case is referred to legal authorities; ICHI contains no code representing a medicolegal referral or the administrative act of discharge under medicolegal circumstances.
34596002 (Patient discharge, elopement)(not mapped)Elopement (a patient leaving a facility without clinical authorisation) is an administrative discharge circumstance; ICHI does not contain a code for unauthorised self-discharge or elopement, and the generic XG38D0 "Discharge planning" extension code describes a planned process rather than an unplanned departure.
311401005 (Patient education)(not mapped)ICHI structures education as action axis PM combined with a specific target (body function, activity, or behaviour), producing hundreds of targeted "Education about X" codes, but there is no single generic "patient education" category that captures the undifferentiated SNOMED concept. No acceptable ICHI code covers education in a non-specific, whole-patient sense.
241719007 (Patient eye protection)(not mapped)ICHI contains no code representing the provision or application of eye protective equipment to a patient; ophthalmic interventions are categorised around diagnosis and surgical procedures on eye structures, and safety-behaviour codes (VC block) are population- or workplace-oriented rather than covering patient-level protective device application.
91310009 (Patient follow-up to return when and if necessary)(not mapped)This SNOMED concept represents a specific administrative/clinical instruction — an open or PRN (pro re nata) return appointment — for which ICHI has no corresponding category; ICHI's encounter and health-management codes (PZB block) address care coordination and general health encounters but not the specific concept of a conditional self-initiated return.
20541009 (Patient on pass)(not mapped)"Patient on pass" refers to a temporary authorised absence of an inpatient from a facility — an administrative status event with no direct clinical intervention. ICHI does not contain a code for this administrative/status concept; the closest structural codes (discharge planning, individualised planning) do not semantically capture a supervised temporary leave.
184047000 (Patient registration)(not mapped)Patient registration is a purely administrative act of enrolling a patient with a provider or facility; no equivalent exists in ICHI, which focuses on health interventions rather than administrative processes such as enrolment or record creation.
700416004 (Pediatric care)(not mapped)ICHI classifies specific health interventions, not specialty-level care designations; there is no ICHI code or block representing "pediatric care" as a service modality, and no sufficiently related code was found across clinical, rehabilitative, or public-health sections.
183458009 (Pediatric emergency hospital admission)(not mapped)ICHI does not classify care-setting events such as hospital admissions; extensive searches for "admission," "inpatient," "emergency," and related terms returned no relevant codes, confirming this administrative/encounter-type concept falls outside ICHI's scope.
386387004 (Peer review)(not mapped)ICHI does not contain a code for peer review as an administrative or quality assurance process. Despite extensive searching across health service, quality, audit, and health behaviour blocks, no ICHI category corresponds to this organisational/managerial activity; ICHI focuses on health interventions delivered to individuals or populations, not professional review processes.
704135001 (Penile care)(not mapped)ICHI contains surgical and procedural interventions on the penis (block BlockL5-NGM) covering biopsy, excision, repair, prosthesis, etc., but no code represents basic hygiene or nursing care of the penis. The "hygiene behaviours" block (VED) addresses public health behavioural interventions, not direct clinical body care.
240968008 (Percutaneous imaging guided diagnostic aspiration)(not mapped)ICHI organises aspiration (action JB, means AE for percutaneous) only at the level of specific anatomical targets (e.g., gallbladder, prostate, orbit); there is no cross-body-system code for a generic percutaneous image-guided diagnostic aspiration regardless of site. The imaging-guidance specificity further lacks a direct counterpart, making a meaningful single-code mapping impossible.
302766006 (Percutaneous imaging guided therapeutic drainage)(not mapped)Like diagnostic aspiration, ICHI encodes percutaneous drainage (action JB, means AE) only site-specifically (e.g., AAG.JB.AE for intracranial space, KCO.JB.AE for pancreas), with no generic cross-site code for percutaneous image-guided therapeutic drainage. Assigning any single anatomical code would misrepresent the site-agnostic nature of the SNOMED concept.
429737004 (Percutaneous laser ablation of lesion of fetus)(not mapped)The NMR (fetal/embryonic structure) block contains no code for destruction or ablation of a fetal lesion; the only fetal destruction code (NMR.GA.AC) is specifically "Destruction of fetus to facilitate delivery," which has a fundamentally different clinical intent and is not an appropriate match.
1230229003 (Performing search for missing subject of care)(not mapped)ICHI contains no code for actively searching for or locating a missing patient or subject of care; the closest candidates (PZB.VC.ZZ "Infectious disease contact tracing", PZB.TC.ZZ "Navigating the service system") do not capture this concept, and no public health, administrative, or case-management code in ICHI addresses this activity.
391266008 (Perinatal mental health care HRGs)(not mapped)This is a UK NHS Healthcare Resource Group (HRG) administrative billing grouper category, not a clinical intervention. ICHI classifies health interventions, not administrative/financial groupers, so no ICHI code exists for this concept.
48684007 (Pharmacokinetic study)(not mapped)ICHI has no code representing a pharmacokinetic study (i.e., a clinical investigation measuring drug absorption, distribution, metabolism, and excretion). The closest candidate, UAC.AA.ZZ "Assessment of medications," belongs to the environment/products chapter and concerns medication management support, not scientific kinetic measurement; no other code in the clinical investigation or body-systems chapters captures this concept.
257891001 (Photodynamic therapy)(not mapped)ICHI does not contain a code for photodynamic therapy (PDT) — a modality using photosensitising agents activated by light to destroy tissue. Fuzzy and synonym searches (PDT, light therapy, photodynamic) returned no usable results, and no ICHI action or means axis combination corresponding to photosensitiser-plus-light destruction was found across any body section.
229553000 (Physical agent therapy)(not mapped)ICHI does not have a grouper code for "physical agent therapy" as a category — individual modalities such as phototherapy (PZA.SC.AH), hydrotherapy (PZA.ZZ.BS), warming (PZA.SD.BQ), and cooling (PZA.SE.ZZ) are coded separately. The SNOMED concept is an abstract grouper for a set of physical modalities, and no single ICHI code covers that combined scope.
1141750000 (Physiological delivery of placenta)(not mapped)ICHI's placenta block (NMM) covers interventional procedures such as manual removal of retained placenta, biopsy, and drainage — but does not contain any code for the physiological (natural, spontaneous) expulsion of the placenta as a clinical event to be coded. The NUG childbirth-function codes cover assessment and counselling of childbirth functions, not the act of placental delivery itself, and no other ICHI category captures this concept.
164961002 (Physiological function tests)(not mapped)ICHI does contain many body-system-specific test codes (e.g., test of memory, test of exercise tolerance, test of respiratory muscle function) but no single overarching code for "physiological function tests" as a generic category spanning all body functions. Assigning any single-system test code would be far too narrow, and there is no umbrella residual category that covers all-body-function testing.
313206006 (Physiological functions education)(not mapped)ICHI has many body-system-specific education codes (e.g., NUG.PM.ZZ "Education about functions related to childbirth", HT2.PM.ZZ "Education about functions of the cardiovascular system") but no single umbrella code for education about physiological functions in general; any single specific-system code would be far too narrow to represent this broad SNOMED concept.
266739000 (Physiotherapy/remedial therapy)(not mapped)ICHI does not have a single code for "physiotherapy" or "remedial therapy" as a discipline or encounter type; physiotherapy interventions are distributed across dozens of target-specific codes (exercise-leading, manipulation, training, assessment) across multiple body systems, with no single aggregate code representing the physiotherapy modality itself.
8591000202100 (Picking up mail)(not mapped)"Picking up mail" is a highly specific instrumental activity of daily living (IADL) with no corresponding ICHI code — ICHI's activities/participation section (S-chapter) covers broad domains like fine hand use (SIG) or domestic life acquisition (SN2) but contains no code specific to mail retrieval. The concept is too granular and situational for any ICHI category or block to constitute even a reasonable approximate match.
428898005 (Piercing of genital structure)(not mapped)ICHI covers interventions on specific genital structures (penis — NGM, scrotum — NGG, vulva — NMI) but none of these blocks contain a piercing or generic genital incision code that would serve as even a reasonable broad match for cosmetic genital piercing across unspecified genital anatomy. The SNOMED concept is intentionally non-specific as to which genital structure, making any single-structure ICHI code a poor fit, and no umbrella genital piercing code exists.
428985000 (Piercing of umbilicus)(not mapped)ICHI contains no code representing body piercing as a health intervention. The umbilicus block (PAO) only covers biopsy, hernia repair, and local excision — none of which capture the act of piercing the umbilicus for jewellery or other purposes.
410302006 (Positioning education, guidance, and counseling)(not mapped)ICHI contains positioning-as-physical-intervention codes (e.g., PZA.LD.ZZ, PZX.LD.ZZ) and separate education/counselling codes for specific body functions, but has no code combining education, guidance, and counselling specifically about positioning as a therapeutic topic; no reasonable single ICHI code covers this multi-modal educational intervention about positioning.
169334008 (Postoperative external beam radiotherapy)(not mapped)ICHI has body-site-specific destruction-by-radiotherapy codes (e.g., LZZ.GA.BA, NME.GA.BA) but no generic "external beam radiotherapy" code that covers all body sites; the "BA" means axis denotes radiation generally without distinguishing external beam from brachytherapy or other modalities, and no site-nonspecific postoperative radiotherapy code exists.
48995004 (Postoperative fluoroscopy)(not mapped)ICHI contains only one fluoroscopy code (KTC.BA.BB — Video fluoroscopy to evaluate swallowing), which is far too specific; there is no general postoperative or unspecified-site fluoroscopy code, and the generic imaging NEC code (PZX.BA.BL — Image capture and analysis, NEC) does not semantically represent fluoroscopy as a distinct modality.
49730009 (Postoperative follow-up, anesthesia)(not mapped)ICHI classifies anaesthesia as an action axis code (DC — Anaesthesia) used in combination with a target body part; there is no standalone postoperative anaesthesia follow-up or review code, and ICHI does not represent postoperative monitoring or assessment in the context of anaesthesia care as a distinct assignable intervention.
182775008 (Postoperative monitoring)(not mapped)ICHI has no generic "postoperative monitoring" concept; its monitoring codes are all organ- or function-specific (e.g., cardiac monitoring, fetal monitoring, brain monitoring), and none capture the broad, non-site-specific postoperative surveillance intended by this SNOMED concept. The action axis code "AI – Monitoring" exists only as an axis component, not a standalone assignable code.
237014000 (Postpartum obstetric operation)(not mapped)"Postpartum obstetric operation" is a high-level grouping concept in SNOMED CT covering any surgical procedure performed on a woman in the postpartum period; ICHI does not have a corresponding grouping code or block for postpartum operations as a class, and no individual ICHI category captures this concept at the appropriate level of abstraction.
389099004 (Precautionary procedure)(not mapped)"Precautionary procedure" is an extremely broad, non-specific SNOMED concept that acts as a meta-category for any protective or risk-mitigating action; ICHI has no equivalent high-level residual category for generic precautionary interventions, and assigning any specific ICHI code would misrepresent the concept's intended breadth.
386392002 (Preceptoring: student)(not mapped)ICHI has no concept covering clinical preceptoring, mentorship of students, or supervised practice in health education contexts. The nearest candidates (UEP.PH.ZZ "Training about health services" or UEQ.RG.ZZ "Providing education and training services") are far broader public-health/systems-level interventions that do not represent the individualized clinical supervisory relationship of preceptoring a student.
399498001 (Prelymphadenectomy treatment)(not mapped)"Prelymphadenectomy treatment" refers to any intervention (e.g. radiotherapy, chemotherapy, immunotherapy) administered before a planned lymph node dissection; this is a contextual qualifier around a subsequent procedure rather than a defined intervention type. ICHI has no code capturing a pre-lymphadenectomy treatment category, and no individual treatment code adequately represents this concept without knowing the specific modality.
370830002 (Preoperative education including family and support persons)(not mapped)ICHI contains no code for education delivered specifically in a preoperative context to patients, family, and support persons; available education codes are either topic-specific body function codes or population-level health services education (UEP.PM.ZZ), neither of which captures perioperative patient-and-family education as a distinct clinical intervention.
714029009 (Preoperative high dose brachytherapy)(not mapped)ICHI does not have an assignable intervention code for brachytherapy as a standalone procedure; the only radiation-related hits are site-specific radiotherapy destruction codes and extension/means codes (Brachytherapy seeds, Interstitial radioactive material) that lack standalone code values, and none are specific to high-dose-rate preoperative brachytherapy.
40791000 (Preparation of disability evaluation report)(not mapped)Extensive searching across disability, evaluation, report, assessment, documentation, certification, medico-legal, functional capacity, work capacity, and activity limitation terms returned no relevant ICHI code. ICHI does not appear to include administrative or medico-legal documentation tasks such as preparing disability evaluation reports.
787376009 (Preparation of formalin fixed paraffin embedded tissue specimen)(not mapped)Searches for formalin, fixation (in the histological sense), paraffin, histology, tissue processing, and pathology specimen preparation returned no ICHI code corresponding to this laboratory technique. ICHI's specimen collection codes describe in vivo collection from patients, not the ex vivo laboratory processing and embedding of tissue specimens.
103695000 (Preparation of medical certificate)(not mapped)ICHI does not include administrative documentation activities such as writing or issuing a medical certificate; the classification focuses on clinical, rehabilitative, and public-health interventions, not medico-legal or administrative outputs.
787374007 (Preparation of plastic embedded tissue specimen)(not mapped)ICHI does not cover laboratory specimen processing or histological preparation techniques such as plastic (resin) embedding; specimen collection codes exist (e.g., PZX.AH.XH) but the post-collection laboratory processing of tissue is outside ICHI's scope.
69619008 (Preparation of routine medical insurance claim)(not mapped)ICHI does not classify administrative or clerical health system activities such as insurance claim preparation; its scope covers clinical, rehabilitative, and public health interventions. No block or category corresponds to the preparation of an insurance claim document.
1155762004 (Preparation of subject for exercise)(not mapped)ICHI contains numerous exercise-related codes (training, education, assessment of exercise tolerance under HTM and VEB blocks), but none specifically describes pre-exercise preparation of a subject (e.g., warm-up, positioning, or equipment fitting before exercise); the concept is a distinct preparatory procedural step not represented in the classification.
49978002 (Preparation of written report for lawyer)(not mapped)ICHI does not contain codes for administrative or medicolegal documentation tasks such as preparing written reports for legal purposes. The classification covers health interventions on body systems, functions, activities, environment, and health behaviours — medicolegal reporting is outside this scope.
386397008 (Presence)(not mapped)"Presence" as a standalone SNOMED concept (denoting a clinician's physical attendance or attendance-based intervention) has no corresponding ICHI code; ICHI does not classify mere attendance or presence as a health intervention category.
58216002 (Preventive incision)(not mapped)ICHI does not have a concept for a "preventive incision" — its incision codes (action FA) are all organ/tissue-specific and none carry a prophylactic qualifier. The SNOMED concept is an abstract procedural category that has no counterpart at any level of the ICHI hierarchy.
80341003 (Primary audit)(not mapped)"Primary audit" refers to a systematic review of clinical practice quality, which is an administrative/governance activity not represented in ICHI; exhaustive searching across clinical, public health, and health-service intervention categories yielded no category corresponding to clinical or health audit.
315233008 (Primary prevention)(not mapped)"Primary prevention" is a high-level conceptual category, not an assignable health intervention in ICHI. ICHI does not have a single code for this concept; prevention activities in ICHI are encoded at the level of specific target behaviours or environmental actions (e.g., VDA for immunisation behaviours, VE1 for lifestyle behaviours), none of which correspond to the undifferentiated SNOMED concept.
315610002 (Primary prevention of ischemic heart disease)(not mapped)ICHI does not classify interventions by disease-target outcome (e.g., "prevention of ischemic heart disease"); instead it classifies by the type of action taken on a target (behaviours, risk factors, body structures). No ICHI code or block corresponds to cardiovascular-disease-specific primary prevention as an undifferentiated concept, making a meaningful mapping impossible.
223464006 (Procedure education)(not mapped)ICHI education codes are all anchored to specific body functions or health domains (e.g., education about cardiovascular functions, education about memory) and there is no generic "procedure education" or pre-procedure patient education code in the classification; the SNOMED concept represents a distinct administrative/clinical communication activity not representable in ICHI.
439531009 (Procedure on artery using imaging guidance)(not mapped)ICHI encodes the means of an intervention (e.g., imaging approach) as an axis within individual procedure codes rather than as a standalone grouper concept; there is no ICHI block or category representing "any arterial procedure performed under imaging guidance" as a cross-cutting class, so no reasonable single ICHI code maps to this SNOMED concept.
129152004 (Procedure on back)(not mapped)ICHI does not have a single block or category representing all procedures on the back as a region; back-related interventions are distributed across multiple separate blocks (vertebral column, musculoskeletal structures of trunk, skin of trunk, etc.) with no unifying "back" grouper, so no single ICHI code adequately covers this SNOMED concept.
118776007 (Procedure on duct)(not mapped)ICHI does not have a single cross-system "duct" block — duct procedures are distributed across anatomical system blocks (bile duct under KCM, thoracic duct under DFP, salivary duct under KAM, pancreatic duct under KCO, ductus arteriosus under HIJ). No single ICHI code or block covers the full semantic breadth of the SNOMED parent concept "Procedure on duct."
118693000 (Procedure on neck)(not mapped)ICHI does not have a single overarching "interventions on neck" block; neck procedures are distributed across multiple organ- and system-specific blocks (vessels, lymph nodes, muscles, thyroid, parathyroid, larynx, etc.). No single ICHI code or block captures the full breadth of this anatomical grouping.
118857000 (Procedure on periurethral tissue)(not mapped)ICHI contains no code or block specifically addressing periurethral tissue; the urethra block (BlockL5-NAM) covers interventions on the urethra itself, not the surrounding connective tissue. No sufficiently close ICHI concept.
128311006 (Procedure on serous sac)(not mapped)ICHI has no concept of "serous sac" as a unified target; its serous membrane structures (pleura, pericardium, peritoneum) are classified under entirely separate body-system chapters (JCA, HFF, KMA), and no cross-cutting block corresponds.
118694006 (Procedure on trunk)(not mapped)ICHI has no single block or code representing "interventions on the trunk" as a whole; trunk procedures are distributed across multiple chapters covering integument, musculoskeletal, thoracic, and abdominal subsections with no common parent grouping.
118853001 (Procedure on urachus)(not mapped)ICHI contains only an extension/supplementary code for "Urachus" (XA1NC2) used as an axis value, and no assignable intervention category or block exists specifically for procedures on the urachus.
416393001 (Procedure time out)(not mapped)"Procedure time out" is a perioperative patient safety activity with no equivalent in ICHI; ICHI does not classify surgical safety administrative activities, checklists, or perioperative protocols.
442220001 (Progesterone withdrawal test)(not mapped)The progesterone withdrawal test has no corresponding assignable ICHI code; ICHI does not represent hormonal challenge/withdrawal diagnostic tests at this level of specificity.
183019009 (Promotion of healing)(not mapped)"Promotion of healing" is a high-level therapeutic goal rather than a specific intervention, and ICHI contains no code that maps to this concept — wound care codes are surgical and there is no general "promote healing" intervention category.
274065009 (Prosthetic limb replacement)(not mapped)ICHI does not contain a surgical procedure code for fitting or replacing a prosthetic limb as a body-system intervention; the closest environmental codes cover provision of assistive technology rather than the clinical surgical or prosthetist act of prosthetic limb fitting.
229614000 (Protection of stump technique)(not mapped)"Protection of stump technique" refers to post-amputation residual limb care to prepare the stump for prosthetic fitting; ICHI has no code for stump care, stump protection, or residual limb management.
370849003 (Provides status reports to family/support person)(not mapped)ICHI has no code representing the act of communicating a patient's clinical status to family members or support persons; this falls outside the ICHI classification scope of assignable health interventions.
370842007 (Providing care in a nonprejudicial manner)(not mapped)ICHI does not encode care delivery attitudes or ethical stances such as non-discriminatory or non-prejudicial care; these are professional conduct principles rather than classifiable health interventions.
370843002 (Providing care respecting the worth and dignity of the patient)(not mapped)Respecting patient dignity is an ethical care principle rather than a discrete health intervention; ICHI contains no code for this concept and no sufficiently close proxy exists.
243748009 (Provision for visual and hearing impairment)(not mapped)ICHI has separate tracks for visual function interventions (BTB block) and hearing function interventions (CTB block), but no single combined code addresses concurrent provision for both visual and hearing impairment.
716736000 (Provision of commercial flight)(not mapped)ICHI has no concept for arranging or providing commercial air transportation; this SNOMED concept sits outside ICHI's scope of health interventions on individuals, body systems, or public health actions.
439894008 (Provision of device)(not mapped)ICHI has no generic "provision of device" category; every device-related code in ICHI is body-site- and action-specific. This SNOMED concept is a high-level organisational parent for which no single ICHI code provides an equivalent.
312633007 (Provision of suction equipment)(not mapped)The SNOMED concept describes supplying or providing suction apparatus (e.g., for home or ward use) rather than performing a suctioning procedure; ICHI codes suctioning as a clinical procedure (e.g., JZZ.JB.AC for airway suctioning) but has no code for the act of providing or issuing suction equipment to a patient or setting.
183455007 (Psychiatric emergency hospital admission)(not mapped)ICHI does not classify hospital admissions or inpatient encounters as distinct intervention types; it classifies what is done to or for a person, not the care-setting event. No ICHI code exists for the act of emergency psychiatric admission, making a meaningful mapping impossible.
24642003 (Psychiatry procedure or service)(not mapped)This SNOMED concept is a high-level grouper covering the entire domain of psychiatric procedures and services, with no single counterpart in ICHI. ICHI represents individual, granular psychiatric interventions (e.g. assessment of mental functions, psychotherapy) rather than a whole-specialty grouper, so no single ICHI code can represent this concept.
183474004 (Psychogeriatric emergency hospital admission)(not mapped)Like psychiatric emergency admission, ICHI does not represent inpatient admission events or care-setting placements as coded interventions. There is also no age-specific (geriatric) or specialty-specific (psychogeriatric) admission axis in ICHI, leaving no viable mapping target.
165168001 (Psychotropic drug for examination)(not mapped)This SNOMED concept refers to the administration of a psychotropic (sedating or mind-altering) drug specifically to facilitate a clinical examination — a concept combining drug administration means with a psychiatric/examination purpose; ICHI has no assignable code that captures this specific combination, and the closest candidates (anaesthesia codes, medication-related UAC codes) do not reflect the psychotropic-for-examination intent.
422463007 (Pulmonary artery catheter care)(not mapped)ICHI does not contain a code for the ongoing care or management of an in-situ pulmonary artery catheter; the pulmonary artery block (BlockL5-HID) covers only procedural interventions such as imaging, excision, and reconstruction, and no catheter monitoring or care maintenance code exists elsewhere in the classification.
1156384006 (Pulsed dose rate brachytherapy)(not mapped)ICHI contains radiotherapy codes structured around tissue-destruction by radiotherapy at specific anatomical targets, but has no procedure code representing brachytherapy (sealed-source internal radiation) as a technique, nor any code that distinguishes dose-rate modalities (pulsed, high, or low dose rate); the only brachytherapy-related entry ("Brachytherapy seeds") lacks an assignable ICHI code, making a reasonable mapping impossible without target-site specificity.
386404008 (Quality monitoring)(not mapped)ICHI does not contain a health system or administrative concept corresponding to quality monitoring, quality assurance, or quality control — its scope covers clinical, rehabilitative, and public health interventions on individuals or populations, not organisational or service-quality surveillance activities.
443862007 (Quantitative measurement of hemoglobin F relative to total hemoglobin in serum or plasma by HPLC)(not mapped)ICHI contains extension/quantifier codes for haemoglobin and HbA1c but no assignable procedure code for fetal haemoglobin (HbF) measurement, and no code reflecting HPLC as a laboratory technique; this specific analytic procedure has no reasonable ICHI match.
385798007 (Radiation therapy care)(not mapped)"Radiation therapy care" is a high-level administrative/nursing care concept encompassing the entire continuum of management surrounding radiotherapy; ICHI's radiotherapy codes are all site-specific destruction codes, and there is no generic care-coordination, patient management, or radiotherapy-care code to map to.
15351005 (Radiocalcium absorption study)(not mapped)No ICHI code exists for a radiocalcium (Ca-47) absorption study. Searches for calcium absorption, radioisotope absorption, isotope study, and related nuclear medicine diagnostic studies returned no matching category; the radioisotope codes found are organ-specific imaging scans, not gastrointestinal absorption function tests.
879916008 (Radiofrequency ablation)(not mapped)ICHI does not have a generic "radiofrequency ablation" code — the term "radiofrequency" returns no results, and ablation results are limited to cardiac and endometrial site-specific procedures. As a stand-alone unspecified-site RFA concept, no assignable ICHI code matches.
252664009 (Radionuclide breath test)(not mapped)No ICHI code exists for a radionuclide breath test (C-13/C-14 urea or fat-absorption). All ICHI radioisotope codes are organ-specific imaging or scan studies; exhaled-gas metabolic tests using radiolabelled substrates are not represented anywhere in the classification.
431429001 (Radionuclide destruction of synovium)(not mapped)Radiosynovectomy (intra-articular injection of a beta-emitting radioisotope to destroy synovium) has no dedicated ICHI code. Joint injection codes do not encode the radioactive/destructive nature, and destruction-by-radiotherapy codes have no synovium target; the concept is absent from ICHI.
348003 (Radionuclide dynamic function study)(not mapped)ICHI encodes radioisotope studies only as organ-specific codes (thyroid, liver, gallbladder, spleen, etc.) with no generic cross-organ "dynamic radionuclide functional study" category; the top-level concept represented by this SNOMED code has no ICHI equivalent.
43129000 (Radionuclide dynamic function study with multiple probes)(not mapped)This is a more granular variant of 348003 (adding the multi-probe acquisition technique), and ICHI lacks even the parent concept; there is no representation of technique-specific nuclear medicine acquisition methods in the classification.
69720006 (Radionuclide special dynamic function study)(not mapped)This SNOMED concept describes a cross-organ category of dynamic (time-series) radionuclide functional studies not tied to any specific anatomy; ICHI has no equivalent broad dynamic nuclear medicine functional study code, and no single organ-specific code captures this generic, multi-organ procedural class.
18499008 (Radionuclide study, protein kinetics)(not mapped)ICHI contains no code for radionuclide-based protein kinetics or tracer-labelled protein turnover studies; this is a highly specialised research/metabolic procedure that falls outside the granularity and scope of ICHI's current nuclear medicine coding. No radioisotope scan or nuclear imaging code addresses protein metabolism or kinetics specifically.
17026004 (Radionuclide tissue clearance study)(not mapped)ICHI contains no code for a radionuclide tissue clearance study — a functional nuclear medicine measurement of the rate at which a radiotracer clears from tissue. The available radioisotope codes in ICHI are all organ-specific scans or whole-body scans (e.g., PZA.BA.BE), none of which captures the clearance/kinetic measurement concept.
1287742003 (Radiotherapy)(not mapped)ICHI has no single umbrella code for radiotherapy as a general category — all its radiotherapy codes are site-specific (e.g., EBA.GA.BA for thyroid, AAA.GA.BA for brain, PZA.GA.BA for total body irradiation). This SNOMED concept is a high-level parent class with no corresponding ICHI equivalent at that level of abstraction.
228722007 (Radiotherapy calculation)(not mapped)ICHI contains no concept for radiotherapy dose calculation as a standalone planning or technical step; all radiotherapy codes in ICHI represent therapeutic destruction of tissue by radiotherapy at specific body sites, not the pre-treatment dosimetry calculation activity.
183469007 (Radiotherapy emergency hospital admission)(not mapped)ICHI classifies health interventions by action on a target, not by care setting or mode of admission; hospital admission — whether emergency or elective — is an administrative act outside ICHI's classification scope.
228703003 (Radiotherapy planning)(not mapped)ICHI has no code for radiotherapy treatment planning as a clinical act; the only radiation-related planning code (UBR.TB.ZZ — Planning in relation to radiation) is a public health environmental intervention, not a clinical pre-treatment planning activity for a cancer patient.
710354007 (Rapid extrication)(not mapped)Rapid extrication is an emergency pre-hospital technique for moving a critically injured patient from a vehicle with minimal spinal precautions; ICHI contains no code for vehicle extrication, patient extraction, or any comparable pre-hospital emergency manoeuvre, and no closely related code provides a reasonable mapping.
223476006 (Reassuring)(not mapped)"Reassuring" is a general communicative or psychological act without a discrete ICHI procedure code; while ICHI contains emotional support and counselling codes, none specifically represent the act of reassuring a patient, and the concept is too vague and non-specific to map to any ICHI category without misrepresenting its meaning.
29119006 (Reattachment of extremity)(not mapped)ICHI has specific reattachment codes for individual structures (hand PMD.LB.AA, foot PND.LB.AA, finger PME.LB.AA, toe PNE.LB.AA) but no single code representing reattachment of an extremity in general, which is the SNOMED concept's level of abstraction. The LB action axis block "Reattachment" exists but is not an assignable category code, and no assignable code covers the full upper or lower extremity as a topographical unit.
371547003 (Reattachment procedure)(not mapped)The SNOMED concept is a high-level abstract category for any reattachment procedure regardless of anatomical site. While ICHI's LB action axis block (code "LB", titled "Reattachment") aligns semantically, it is a block and not an assignable category code, making a valid ICHI code assignment impossible for this fully non-specific concept.
122858002 (Rebase of denture)(not mapped)ICHI does not contain a code for denture rebasing (the clinical procedure of replacing the acrylic base of a removable prosthesis). The dental block (KAE) includes restoration, application of dental devices, and management of external appliances, but none of these capture the specific technique of rebasing a denture base material, leaving no reasonable ICHI match.
787371004 (Recasting of specimen in block)(not mapped)This is a laboratory histopathology processing step (re-embedding tissue in a new paraffin block) that lies entirely outside ICHI's scope; ICHI covers specimen collection but has no codes for downstream lab processing or tissue preparation workflows.
428995007 (Receiving of specimen in laboratory)(not mapped)ICHI models the collection of specimens (AH action axis) but does not include administrative or logistical steps such as laboratory accession or receipt of a specimen, leaving this concept without a reasonable ICHI equivalent.
406216001 (Recommendation to caregiver)(not mapped)ICHI classifies interventions by target body system, function, behaviour domain, or environment — it does not have a cross-cutting category for interventions directed at a caregiver as recipient; the closest extension code (Carer – individual) is an additional descriptor, not a standalone assignable intervention code, so no satisfactory mapping exists.
223447008 (Recommendation to document signs and symptoms)(not mapped)ICHI does not have a code for documenting or recording signs and symptoms as a clinical act; the classification focuses on interventions on body functions, health behaviours, and procedures rather than administrative documentation tasks.
897309004 (Recommendation to maintain supply of blood ketone test strips)(not mapped)ICHI contains no code covering the supply or maintenance of diagnostic test consumables such as blood ketone test strips; the closest candidates address medications and environmental goods, not patient-held point-of-care test strip supplies, and none captures the self-monitoring consumable supply concept encoded in this SNOMED term.
304541006 (Recommendation to perform treatment)(not mapped)ICHI does not include a "recommendation" or "clinical decision" action axis value; the classification covers performed health interventions, not the act of recommending that a treatment be undertaken, and no code captures this concept with sufficient fidelity.
223451005 (Recommendation to report signs and symptoms)(not mapped)ICHI contains no code for advising a patient to self-report or communicate symptoms to a clinician; this concept sits outside the scope of ICHI's performed intervention framework, which does not encode instructions or recommendations given to patients regarding symptom surveillance and reporting.
65854006 (Reexcision)(not mapped)ICHI does not have a generic "reexcision" or repeat-excision category; the concept of a re-operation is represented only as an extension code (XG11E2 "Re-operation"), which is an axis modifier rather than a standalone assignable intervention code. No single ICHI category code covers this concept independently of a specific target and action.
82254000 (Refixation)(not mapped)ICHI has site-specific fixation codes (e.g. fixation of spleen, fixation of intestine) but no generic "refixation" or repeat-fixation category, and no axis modifier equivalent to "redo fixation" exists as an assignable code. The concept is too abstract and target-independent to map to any specific ICHI category.
52052004 (Rehabilitation therapy)(not mapped)ICHI contains no assignable intervention category for rehabilitation therapy as a concept; XG4691 "Rehabilitation and Habilitation" exists only as an extension/descriptive code in the Additional Descriptive Information chapter, not as a standalone health intervention, and no other ICHI category meaningfully captures the broad concept of rehabilitation therapy.
28485005 (Reinforcement)(not mapped)"Reinforcement" as a standalone SNOMED concept is too non-specific to map to any single ICHI code; the only ICHI code containing "reinforcement" is BCB.ML.AA (Reinforcement of sclera), which is a specific ophthalmic procedure and does not represent the general concept. No suitable ICHI match exists for the generic procedure concept.
71140006 (Release of median arcuate ligament)(not mapped)ICHI has no code for division or release of the median arcuate ligament (the fibrous diaphragmatic band released in median arcuate ligament syndrome); the diaphragm block (MCX) lacks a ligament-release code, and no other ICHI code adequately represents this specific procedure without misrepresenting the target anatomy or action.
179261007 (Release of periosteum)(not mapped)ICHI includes periosteum only as an extension code entity (XA6FQ2) with no assignable procedural code for periosteal release or stripping; no code in the musculoskeletal chapters adequately represents this procedure without losing the specificity of the periosteal target.
281180009 (Reline of maxillofacial prosthesis)(not mapped)ICHI contains no code or block specifically addressing maxillofacial prostheses (facial/craniofacial prosthetics such as orbital, nasal, or auricular prostheses), and no general "reline/refit prosthesis" code exists in ICHI. The dental appliance code (KAE.SM.AC) is scoped to teeth and does not extend to maxillofacial prosthetics.
406155005 (Removal of all drains)(not mapped)ICHI has only site-specific drainage device removal codes (e.g., pleural cavity, mediastinum) and no generic or multi-site "removal of all drains" code. The SNOMED concept is explicitly site-nonspecific and cannot be adequately captured by any single ICHI category.
301884003 (Removal of aortic cross clamp)(not mapped)Removal of an aortic cross clamp is an intraoperative step (declamping the aorta) within open cardiac or vascular surgery, not a classifiable standalone health intervention in ICHI; no ICHI code exists for this maneuver or its equivalent.
426305004 (Removal of atrial catheter)(not mapped)ICHI has no code for removal of an atrial catheter; atrial intervention codes cover thrombectomy, plication, baffle procedures, and incision, and cardiac device removal is limited to pacemaker/defibrillator systems (HFC.JD.AA), none of which represent catheter removal from the atrium.
90964006 (Removal of cervical collar)(not mapped)ICHI has a code for applying a cervical external immobilisation device (MBA.LC.AH) but no corresponding code for its removal; removal of an external orthotic device such as a cervical collar is not represented as an assignable ICHI category.
41780001 (Removal of external fetal monitor)(not mapped)ICHI has a code for internal fetal monitoring and monitoring of delivery, but no code representing the placement or removal of an external fetal monitoring device (CTG/tocography transducers); the concept of removing a non-invasive external device is outside ICHI's coding scope.
238205004 (Removal of foreign material from previous herniorraphy)(not mapped)ICHI contains no code for removal of prosthetic mesh or foreign material specifically from a prior hernia repair site; the hernia block (PAM/PAN/PAO) covers only repair operations, and adjacent abdominal wall codes (PAL) cover debridement and suture removal but not prosthetic material explantation from a herniorraphy.
54853009 (Removal of implanted intra-arterial infusion pump)(not mapped)ICHI contains no code for removal of an intra-arterial or intravascular infusion pump; the abdominal/pelvic artery block (IEA) and other arterial blocks do not include a device removal category, and no generic intra-arterial device removal code exists in the classification.
719896005 (Removal of individual from care setting)(not mapped)ICHI does not have a code for the administrative/social act of removing a person from a care setting (such as discharge against will, transfer out of institutional care, or deprivation of care). This concept sits outside ICHI's clinical and public health intervention scope; the closest code found (XG38D0 "Discharge planning") is an extension/supplementary code about planning process, not the act of removal itself.
37897006 (Removal of intra-aortic balloon with repair of aorta)(not mapped)ICHI has no code for removal of an intra-aortic balloon pump combined with aortic repair; the aortic intervention blocks (HIF, HIG, HIH) contain reconstruction and repair codes but none that incorporate concomitant balloon device removal, and the "Intraaortic balloon pump" entry in ICHI appears to be an extension/means code without a matching assignable intervention category covering this compound procedure.
225066003 (Removal of intravenous cannula)(not mapped)ICHI has no code for removal of a peripheral intravenous cannula; the vein-of-upper-limb block (ICD) contains only insertion, extraction of obstruction, occlusion, repositioning, and stent procedures — none covering simple device removal from a peripheral vein. The action code JD exists for central vessels but no peripheral-vein removal code is present in the classification.
297236007 (Removal of object)(not mapped)This SNOMED concept is maximally generic — removal of an unspecified object from an unspecified body site — and ICHI requires both a target body part and a specific action to form an assignable code. No ICHI category exists at this level of generality, and assigning any specific body-site code would be narrower than the SNOMED concept.
240967003 (Removal of oily contrast medium)(not mapped)ICHI contains no code for the removal of retained or injected oily (lipid-based/iodised oil) contrast medium, whether from the spinal canal, lymphatics, or any other site. The classification includes contrast-medium imaging procedures but does not represent the removal of a previously administered contrast agent as a distinct intervention.
177760003 (Removal of prosthesis from chest wall)(not mapped)The chest wall block (PAF) in ICHI contains no device or prosthesis removal code; available codes cover biopsy, drainage, excision, and repair only. No broader ICHI code adequately represents this specific procedure without being misleading.
178212003 (Removal of prosthesis from tendon)(not mapped)ICHI lacks a generic "removal of internal device from tendon" code across all tendon sites; the only tendon-specific device code (MGT.DN.AA) covers implantation in the hand/finger only, and no corresponding removal or broader tendon target exists in the classification.
265148006 (Removal of skeletal traction system)(not mapped)ICHI only contains codes for the application and management of traction and immobilisation devices, not their removal; no code representing removal or discontinuation of a skeletal traction system exists in the classification.
179228000 (Removal of skin traction)(not mapped)ICHI has no concept for removing a skin traction device; skin traction is an external, non-implanted mechanical device and no ICHI code addresses its discontinuation.
266682007 (Removal of unwanted material)(not mapped)"Removal of unwanted material" is a high-level, body-site-agnostic SNOMED grouper concept that does not correspond to any specific ICHI intervention; ICHI codes are always anchored to a specific target and action, so no single ICHI code reasonably represents this generic category.
228118006 (Removing from child register)(not mapped)This is an administrative/social care act (deregistering a child from a child protection register) with no clinical or rehabilitative procedure content; ICHI does not include administrative safeguarding or social welfare registration acts, and searches across health services, administrative, and public health sections of ICHI returned no relevant concept.
225185002 (Removing stoma bag)(not mapped)Exhaustive searches across "stoma bag", "ostomy", "colostomy bag", "appliance", "device management", and "removal of device" found no ICHI code representing the nursing/self-care task of removing or changing a stoma bag/ostomy appliance. ICHI covers the surgical creation or revision of stomas and ostomy care assistive products, but not the routine emptying or detachment of an external pouch.
91301001 (Repair and refitting spectacles)(not mapped)ICHI contains a code for prescribing/providing spectacles as an assistive device but no code for repairing or refitting an existing pair of spectacles, which is a technical/optical technician service rather than a health intervention in the ICHI sense.
14605009 (Repair of cast framework, partial denture)(not mapped)ICHI has no concept for dental prosthesis repair or denture maintenance; the closest codes (restoration of tooth, application of dental device) address tooth-level interventions rather than repair of a removable partial denture framework, which is a dental laboratory/prosthodontic activity outside ICHI's current scope.
441095006 (Repair of central venous access device with subcutaneous pump)(not mapped)ICHI contains codes for insertion and replacement of central venous catheters and implanted ports but has no assignable code for repair of such a device, and no repair/maintenance action on a subcutaneous infusion pump exists in the classification.
86288009 (Repair of dental implant)(not mapped)ICHI contains codes for placing a prosthetic dental implant, restoring a tooth, and managing external tooth appliances, but none of these captures the distinct concept of repairing a previously placed dental implant fixture.
178086001 (Repair of fascia)(not mapped)ICHI encodes fascia repair only at specific anatomical sites (e.g., MGL.MK.AA for hand/finger, MDL.LB for shoulder) with no generic unspecified-site "repair of fascia" code; the SNOMED concept is anatomically unspecified, so no single site-specific ICHI category is an appropriate mapping.
48668006 (Repair of fascia by graft of tendon)(not mapped)ICHI has site-specific reconstruction-of-fascia codes but no code for reconstruction of fascia using a tendon graft at an unspecified site; the specificity of the graft material (tendon) and the absence of a site-neutral fascia reconstruction code leave this concept without a reasonable ICHI match.
1335929005 (Repair of head)(not mapped)The ICHI "head or neck, not otherwise specified" block contains no repair code — only measurement, imaging, and assistive product interventions; no ICHI category captures a generic, unspecified repair of the head.
41117000 (Repair of hernia of fascia)(not mapped)ICHI hernia repair codes are all site-specific (inguinal, femoral, umbilical) with no generic "fascial hernia repair" category, and a hernia of fascia can occur at any anatomical location; the SNOMED concept's anatomical unspecificity prevents a reasonable mapping to any single ICHI code.
52172007 (Repair of ligament)(not mapped)ICHI organises ligament repair exclusively by anatomical site (knee, shoulder, wrist, hand, etc.) and has no generic "repair of ligament" category at a body-site-agnostic level, so no single ICHI code corresponds to this high-level SNOMED grouper concept.
782684008 (Repair of peripherally inserted central catheter)(not mapped)ICHI does not contain a code representing repair or maintenance of an existing intravascular catheter (PICC); the closest codes relate to insertion, replacement, or removal of catheters, and none capture the act of repairing a catheter that remains in situ.
119593002 (Repair of trunk)(not mapped)ICHI has no assignable category code for a generic "repair of trunk" — BlockL5-PAA contains only measurement, immobilisation, and assistive product codes, with no repair action, and the specific trunk wall repair codes (PAF.MK.AA chest wall, PAL.MK.AA abdominal wall) are too narrow to represent this undifferentiated concept.
235195004 (Replacement of implanted antireflux prosthesis)(not mapped)ICHI contains no code for replacement (or management) of an antireflux device such as a magnetic sphincter augmentation; the gastroesophageal junction block (KBE) covers only release and repair procedures, and no oesophageal or gastrointestinal replacement code covers an antireflux prosthesis specifically.
85202001 (Replacement of prosthesis of extremity, bioelectric or cineplastic)(not mapped)ICHI contains no codes for fitting or replacing external limb prostheses (myoelectric/bioelectric or cineplastic); musculoskeletal replacement codes in ICHI cover only internal implanted devices such as joint prostheses, not externally worn limb prosthetics, leaving no reasonable match for this concept.
1747001 (Replacement of skeletal muscle stimulator)(not mapped)ICHI has no code for replacing a skeletal muscle stimulator device; the closest structural candidates (MRM.DN.AA for device implantation into muscle, or ACA.KA.AE for peripheral nerve device replacement) do not capture the concept of replacing an implanted electrical stimulator specifically targeting skeletal muscle.
373188003 (Replacement procedure)(not mapped)"Replacement procedure" is a high-level abstract SNOMED concept representing an entire category of procedures and is not itself a specific clinical intervention; ICHI provides no equivalent top-level abstract grouper code.
117615005 (Report of transfusion reaction)(not mapped)Reporting a transfusion reaction is an administrative/haemovigilance documentation act, not a clinical intervention on a body system; ICHI does not include codes for adverse event reporting or notification activities.
1366481001 (Request for document translation service)(not mapped)ICHI has no code representing a request or administrative act for document translation; the classification covers health interventions rather than administrative or logistical service requests.
445075008 (Request for language interpreter service)(not mapped)ICHI does not contain a code for requesting a language interpreter; this is an administrative support action outside the scope of the classification.
704199009 (Request for postmortem examination)(not mapped)A "request" for postmortem examination is an administrative act, not a health intervention performed on a patient — it falls outside ICHI's scope. The closest ICHI code PZA.AE.AA (Autopsy) represents the examination itself, not the administrative request for it.
386409003 (Research data collection)(not mapped)ICHI does not contain a code for research data collection as a health intervention category; its population-level codes cover surveillance and public health monitoring but do not capture the concept of research data gathering as a distinct intervention.
408489005 (Respiratory emergency hospital admission)(not mapped)ICHI classifies health interventions by clinical action, not by administrative events such as hospital admission or care episode initiation; no ICHI code exists for the act of admitting a patient to hospital for a respiratory emergency.
35497000 (Restraint maintenance)(not mapped)ICHI contains no code for physical restraint, chemical restraint, or the monitoring/maintenance of a restraint device applied to a patient.
386411007 (Resuscitation of fetus)(not mapped)ICHI has no dedicated code for fetal resuscitation — the fetal interventions block covers monitoring, infusion, rotation, and structural repair but not resuscitation; HT2.MC.AH is scoped to the cardiovascular system generally and is not fetal-specific.
81611004 (Retrospective audit)(not mapped)ICHI does not contain any concept corresponding to a clinical or administrative audit. A retrospective audit is a quality assurance/governance activity that falls outside ICHI's scope of health interventions on body systems, functions, behaviours, or the environment.
1234814002 (Return of subjects valuables and belongings)(not mapped)This is an administrative/logistical act during patient discharge that has no counterpart in the ICHI classification, which covers clinical, rehabilitative, and public health interventions.
398180003 (Reversal of anesthesia using a specific drug reversal agent)(not mapped)ICHI contains codes for administration of anaesthesia but has no code representing reversal or antagonism of anaesthetic agents; this pharmacological intervention (e.g., neostigmine, sugammadex, naloxone) is not represented in the ICHI classification.
398121001 (Reversal of anesthesia using stimulant drug)(not mapped)ICHI contains codes for the administration of anaesthesia but has no code representing the pharmacological reversal or antagonism of anaesthesia using a stimulant agent. No adequate match exists at any level of the hierarchy.
241703000 (Reversal of neuromuscular blockade)(not mapped)ICHI contains no codes for the pharmacological reversal of neuromuscular blockade (e.g., neostigmine or sugammadex); neither the neuromuscular junction target nor a relevant action axis combination for antagonism of a blocking agent could be identified.
866039004 (Review specimen from own archive)(not mapped)ICHI covers specimen collection but has no concept for reviewing or re-examining a previously collected specimen from an archive. This is a pathology/laboratory administrative procedure that falls outside ICHI's scope.
128323000 (Revision of implant)(not mapped)ICHI has site-specific "replacement of internal device" codes (action axis KA) but no single generic code covering revision of an implant at any unspecified body site. The SNOMED concept is deliberately non-specific (implant of any type, any site) and no ICHI category or block captures that breadth without over-restricting the anatomy.
288166008 (Revision of prosthesis)(not mapped)ICHI has no generic "revision of prosthesis" category spanning all body sites and prosthesis types. Site-specific "Replacement of [site] device/prosthesis" codes exist (e.g. MLJ.KA.AA for hip), but the SNOMED concept is intentionally body-site-agnostic, and no single ICHI category corresponds to that breadth.
449562006 (Revision of prosthetic replacement of joint using cement)(not mapped)ICHI offers per-joint "Replacement of [joint] joint device" codes (e.g. MLJ.KA.AA for hip, MMJ.KA.AA for knee) but no joint-unspecified equivalent, and none encode cement fixation as a distinguishing feature; the SNOMED concept's combination of unspecified joint site and cement technique has no adequate ICHI counterpart.
178186003 (Revision of tenolysis)(not mapped)Tenolysis is the surgical release of tendon adhesions, and "revision of tenolysis" means repeating or reworking that release — a concept that does not map cleanly to any ICHI action. While ICHI has site-specific "Release of tendon" codes (e.g., MNT.FC.AA, MOT.FC.AA), these encode the original tenolysis procedure and do not capture the "revision" semantic; without knowing the anatomical site and given no site-agnostic revision code exists, no reasonable single ICHI code can be assigned.
179818002 (Revision repair extra-articular ligament)(not mapped)ICHI has no generic "ligament of unspecified site" repair or reconstruction category, and no extra-articular ligament concept; all ICHI ligament repair codes are site-specific (knee, shoulder, wrist, etc.) and none adequately represents a body-site-unspecified extra-articular ligament repair revision.
179190007 (Revision to arthroscopic reduction and fixation of fracture)(not mapped)ICHI arthroscopic reduction codes all require a specific joint site (knee, shoulder, wrist, etc.) and ICHI has no fracture fixation category or revision-specific arthroscopic procedure; no code adequately captures a site-unspecified revision to arthroscopic fracture reduction and fixation.
179110006 (Revision to wire fixation of fracture)(not mapped)No ICHI code represents revision (replacement/re-fixation) of wire fracture fixation at an unspecified skeletal site. The closest candidates — MRB.JD.AA (removal of internal device from bone, unspecified) and MRB.LD.AA (open reduction of bone, unspecified) — each capture only one component of this two-part concept (device revision plus fracture reduction) and are insufficiently close for a defensible mapping.
179791001 (Revision xenograft augmentation extra-articular ligament)(not mapped)ICHI contains no code for extra-articular ligament procedures, nor any code referencing xenograft augmentation of a ligament. The available ligament reconstruction codes (e.g. MML.ML.AA) are knee-specific intra-articular reconstructions, making them insufficiently related to this revision of an extra-articular xenograft augmentation at an unspecified site.
183465001 (Rheumatology emergency hospital admission)(not mapped)ICHI does not contain codes for specialty-specific or emergency hospital admissions as administrative/encounter events; no code in the classification covers the concept of an emergency inpatient admission to a rheumatology service.
171141009 (Rickettsia screening)(not mapped)ICHI contains no code for Rickettsia or rickettsial disease screening; the classification lacks pathogen-specific infectious disease screening codes at this level of specificity, and no sufficiently related code exists in the laboratory testing, specimen collection, or public health surveillance sections.
413137002 (Risk management administration)(not mapped)ICHI does not contain a code for administrative risk management processes. This SNOMED concept refers to organisational/administrative activity rather than a health intervention directed at a patient or population, which falls outside the ICHI scope of clinical, rehabilitative, and public health interventions.
713090007 (Risk reduction technique)(not mapped)"Risk reduction technique" is a high-level SNOMED grouper concept with no equivalent single ICHI code. ICHI encodes specific risk-reduction interventions targeting particular behaviours (e.g. safety, tobacco, violence) rather than a generic cross-cutting technique category; no single ICHI code captures this breadth.
287668008 (Ritual nasal septum piercing)(not mapped)ICHI does not include body piercing procedures, ritual or otherwise. The nasal septum block contains only clinical/surgical interventions (biopsy, septotomy, submucous resection, septoplasty) — none correspond to piercing as a cultural or ritual act.
228577001 (Role modeling technique)(not mapped)Role modeling is a specific behavioural/educational technique (demonstrating behaviour for a patient to imitate) used in psychology, rehabilitation, and health promotion, but ICHI has no code that corresponds to it — the closest candidates (counselling, training, peer support, psychotherapy, awareness-raising) all represent distinct intervention types.
20019002 (Rolling of conjunctiva)(not mapped)ICHI contains no code for rolling or manual manipulation of the conjunctiva; the conjunctiva block (BlockL5-BBA) only covers biopsy, incision, release, drainage, excision, repair, and reconstruction — none of which capture the rolling/mobilisation technique described by this SNOMED concept.
241743005 (Room temperature decreased)(not mapped)ICHI has no code for adjusting or decreasing room ambient temperature; the environment chapter covers large-scale climate and indoor air quality interventions at a population level, and cooling codes (PZA.SE.ZZ, PZX.SE.ZZ) refer to lowering a patient's body temperature, not room temperature.
241742000 (Room temperature increased)(not mapped)ICHI has no code for increasing room ambient temperature; warming codes (PZA.SD.BQ, PZX.SD.BQ) address raising a patient's body temperature, not room temperature, and no environmental block specifically covers bedside room temperature adjustment as a health intervention.
1354566005 (Rotationplasty)(not mapped)Rotationplasty is a highly specific limb-salvage procedure (Van Nes procedure) combining femoral osteotomy, tumour resection, and 180-degree rotation of the distal limb so the ankle functions as a knee joint — no ICHI code captures this composite operation. The closest individual components (MLB.FA.AA Osteotomy of femur, MLB.JN.AA Above knee amputation) each represent only one aspect and would fundamentally misrepresent the procedure.
3780001 (Routine patient disposition, no follow-up planned)(not mapped)This SNOMED concept represents an administrative/clinical decision outcome (patient is discharged with no follow-up required) rather than a health intervention performed on or for the patient; ICHI codes represent interventions, not disposition decisions or encounter outcomes, so there is no reasonable ICHI mapping.
314098000 (Rubella screening test)(not mapped)ICHI's essential laboratory test block (BlockL1-XG1) covers specific viral tests (HIV, HCV, dengue, HPV, etc.) but contains no rubella/German measles antibody or antigen test. The public-health screening-behaviour codes (VDB) relate to screening as a behaviour rather than the diagnostic test itself, so no reasonable ICHI match exists.
401096005 (Sample analysis)(not mapped)ICHI does not contain a generic "sample analysis" procedure code; the classification covers specimen collection (action AH) and specific laboratory tests by body system, but lacks a general cross-specimen analytic process category. The SNOMED concept is a methodological/process category at a level of abstraction not represented in ICHI's intervention structure.
117351005 (Sample dilution method for analyte measurement)(not mapped)This SNOMED concept describes a specific laboratory technique (serial dilution prior to analyte measurement), which is a procedural method rather than a classifiable health intervention in ICHI's framework. No ICHI code covers laboratory sample preparation methods at this level of technical specificity.
422424000 (Scheduling instructions)(not mapped)"Scheduling instructions" is an administrative/clerical activity — communicating appointment or follow-up timing to a patient — and falls outside ICHI's scope of health interventions on body systems, functions, environment, or behaviours. No ICHI code reasonably represents this concept.
840341006 (Screening for detection of implant)(not mapped)ICHI contains many codes for implantation and removal of specific devices, but no code exists for screening or detecting the presence of an existing implant as a standalone clinical act. No suitable ICHI category covers this concept, which typically occurs in the context of pre-procedural safety checks (e.g., before MRI).
792051000000104 (Screening test for diuretic drug)(not mapped)ICHI has no code for therapeutic drug monitoring or screening for a specific drug class such as diuretics; the closest candidates (illicit drug testing, assessment of substances for personal consumption) are too semantically distant to represent a clinical laboratory test for a prescribed diuretic drug.
62407006 (Search for dangerous objects)(not mapped)"Search for dangerous objects" is a security/safeguarding procedure (e.g., pat-down or metal-detector screening) that falls entirely outside ICHI's scope, which covers health interventions; no ICHI code addresses physical security searches or contraband detection.
315234002 (Secondary prevention)(not mapped)"Secondary prevention" is a high-level conceptual category spanning early detection and treatment to halt disease progression, rather than a discrete health intervention; ICHI codes specific preventive actions (screening, immunisation, surveillance) but has no single code representing secondary prevention as an abstract category.
390812001 (Secure and high-dependency mental health care)(not mapped)ICHI contains no code representing admission to or care within a secure or high-dependency psychiatric setting; this concept describes a care environment and intensity level rather than a discrete health intervention classifiable in ICHI.
370855008 (Securing patient's records, belongings, and valuables)(not mapped)This is an administrative/custodial act (safekeeping of property) that falls entirely outside the scope of ICHI, which classifies health interventions; no relevant ICHI code exists.
398012004 (Sedation reversal using a specific sedative drug reversal agent)(not mapped)ICHI contains no code for administration of a reversal or antagonist agent (e.g., flumazenil or naloxone for sedation reversal); there is no action corresponding to pharmacological reversal of sedation, and neither "antidote," "antagonist," nor "reversal" yield any ICHI results.
409978001 (Self-examination)(not mapped)ICHI examination codes (AE action) are all clinician-performed examinations of specific anatomical targets; there is no ICHI code representing self-examination as a patient-performed health behaviour, and no rehabilitation or public-health code covers the generic concept of a patient examining themselves.
406183007 (Self-hypnosis facilitation)(not mapped)ICHI contains no code for hypnosis or hypnotherapy in any form; searches for "hypnosis", "hypnotherapy", "trance", "relaxation", "mind body", and related psychotherapy and cognitive intervention categories all returned no relevant matches, leaving this concept without a mappable ICHI counterpart.
449314004 (Separation of symmetrical conjoined twins)(not mapped)ICHI contains no code representing surgical separation of conjoined twins; this is an extraordinarily rare, multi-system operative procedure with no corresponding entry anywhere in the ICHI hierarchy, including whole-body or general surgical sections.
56082007 (Separation of unequal conjoined twins)(not mapped)Like its symmetrical counterpart, surgical separation of unequal (parasitic) conjoined twins has no ICHI representation; the classification does not cover this procedure in any form, including under whole-body or NEC categories.
401136009 (Servicing equipment)(not mapped)ICHI contains no category or block corresponding to the servicing, maintenance, or repair of health equipment as a standalone intervention type. The equipment-related codes in ICHI concern using equipment in rehabilitation or restricting/providing equipment, not technical servicing activities.
386436001 (Shock prevention)(not mapped)ICHI does not contain a code or block representing prevention of circulatory/physiologic shock as a distinct intervention; searches across prevention, shock, hemodynamic, resuscitation, and related terms found no suitable concept, as ICHI's scope covers discrete interventions rather than this type of clinical management goal.
59705002 (Short wave diathermy)(not mapped)ICHI does not encode short wave diathermy (a specific electromagnetic/radiofrequency deep-heating physical therapy modality); searches for diathermy, thermotherapy, electrotherapy, electromagnetic, radiofrequency, and physical therapy modalities returned no relevant results, and the hyperthermy codes found refer to a different mechanism (direct heat application) rather than shortwave electromagnetic therapy.
225350005 (Showing the client respect)(not mapped)ICHI does not contain a code representing the act of showing a patient/client respect, which is a relational/ethical nursing behaviour rather than a classifiable health intervention; no relevant concepts were found across searches for respect, dignity, patient rights, communication, or interpersonal interventions at the required level of specificity.
112693006 (Slitting)(not mapped)"Slitting" is a site-agnostic surgical technique (a narrow incision) with no corresponding body-structure-independent code in ICHI, which always encodes incision (action FA) paired with a specific anatomical target; no meaningful mapping is possible without a target site.
257930001 (Soft tissue slinging)(not mapped)ICHI has no concept for soft tissue slinging as a generic technique; the suspension codes present (e.g., NAK.LC.AA, NMH.LC.AA) are all organ-specific and do not represent the general procedure of using a sling/fascial strip to support soft tissue. The strapping/taping code (MZZ.DP.AH) addresses proprioceptive taping rather than surgical or procedural slinging, making no adequate match available.
118448000 (Sounding)(not mapped)Sounding (passing a sound instrument through a body orifice to assess patency, measure depth, or dilate — classically uterine or urethral sounding) has no direct ICHI equivalent; the uterus block (NME) contains no sounding or calibration code, and no generic or site-unspecified sounding/probing code exists in ICHI.
66421005 (Special back care)(not mapped)ICHI contains numerous specific back and spine intervention codes (imaging, fusion, biopsy, etc.) but no generic "back care" or back health maintenance/education code that would represent the holistic, non-specific nature of this SNOMED concept; ergonomics (XG90D5) is an extension code, not a clinical intervention category, and does not adequately represent this concept.
1699009 (Special dosimetry)(not mapped)"Special dosimetry" is a radiation physics planning activity (measuring and calculating absorbed radiation doses for radiotherapy), and ICHI contains no dosimetry, radiotherapy planning, or radiation measurement codes — the radiation-related ICHI codes cover either tissue destruction by radiotherapy (e.g. AAA.GA.BA) or public health interventions on radiation (UBR block), neither of which captures dosimetry as a clinical physics service.
315638005 (Special needs support)(not mapped)"Special needs support" is a broad administrative/social concept covering disability-related accommodations; while ICHI has many support codes (practical support, emotional support, social support services under UCH/UEO blocks), none of these correspond specifically to "special needs" support as understood in SNOMED — the closest blocks (UCH, UEO) target personal care providers and general social support systems respectively, and assigning one would be too inexact to be meaningful.
80246006 (Special stain, blood or bone marrow, explain by report)(not mapped)Special staining of blood or bone marrow smears is a laboratory/histochemistry procedure with no corresponding ICHI code; ICHI does contain a bone marrow block (BlockL4-DGA) and a haematological system assessment code (DTA.AC.ZZ — test of haematological system functions), but none specifically represent cytochemical or special staining techniques on haematological specimens.
385830008 (Specimen care)(not mapped)"Specimen care" refers to the handling, transport, and preservation of biological specimens after collection — a laboratory support activity; while ICHI has extensive specimen collection codes (AH axis codes for various sites), it does not have codes for post-collection specimen handling or care, making this concept unmatched in ICHI.
385829003 (Specimen care assessment)(not mapped)ICHI contains no code for the assessment of specimens themselves as objects (e.g. adequacy, quality, or suitability of a biological sample). This pre-analytical/laboratory activity falls outside ICHI's coding scope, which focuses on interventions directed at persons, body systems, or population-level targets.
116707006 (Specimen color determination)(not mapped)ICHI has no code for determining the physical properties (such as color) of a biological specimen; this is a specific laboratory observation/measurement step that falls outside ICHI's classification of health interventions directed at persons or populations.
115267000 (Specimen description)(not mapped)"Specimen description" is a documentation/recording activity (macroscopic or gross description of a pathology specimen) that has no counterpart in ICHI, which does not classify pre-analytical or administrative specimen-handling steps. No search across synonyms (macroscopic examination, gross pathology, documentation, recording) returned a plausible match.
117340005 (Specimen dilution laboratory test method)(not mapped)"Specimen dilution" is a laboratory methodology qualifier describing how a test is performed, not a classifiable health intervention in its own right; ICHI does not model pre-analytical specimen preparation techniques. Searches for dilution, quantitative, and laboratory test method returned no relevant codes.
866038007 (Specimen dispatch)(not mapped)Specimen dispatch is a logistical/administrative act of sending a collected specimen to a laboratory, which falls outside the scope of ICHI clinical interventions. Searches for dispatch, transport, transfer, referral, and delivery yielded no codes applicable to specimen logistics.
103761008 (Specimen dry weight measurement)(not mapped)Dry weight measurement of a specimen is a gravimetric laboratory pre-analytical or analytical technique; ICHI classifies clinical interventions on body systems and does not represent bench-level specimen measurement procedures. No searches for weight measurement, measurement, or haematological measurement produced a matching code.
103760009 (Specimen mass measurement)(not mapped)ICHI does not contain any code for measuring the mass or weight of a specimen; its measurement codes address physiological parameters (blood pressure, body temperature, whole body measurement) and organ/tissue measurements in vivo, not gravimetric analysis of collected specimens. This is a laboratory bench procedure outside ICHI's classification scope.
56245008 (Specimen preparation)(not mapped)ICHI covers specimen collection (action AH, e.g. NGD.AH.XE) but does not represent the downstream laboratory step of preparing a collected specimen for analysis; the action axis code SI (Preparation) appears only in the context of skin preparation (LZZ.SI.ZZ) and as a bare action-axis concept, not as an assignable intervention code for specimen processing.
127790008 (Staining method)(not mapped)ICHI does not classify laboratory staining techniques as interventions; staining is a pre-analytical/analytical laboratory technique outside ICHI's scope of health interventions.
722295003 (Step down change in telehealth monitoring)(not mapped)ICHI's Telehealth block contains only extension codes describing modality of delivery rather than care-level transitions; there is no ICHI code representing a change in monitoring intensity or step-down within a telehealth service.
395096001 (Stereotactic radiotherapy)(not mapped)ICHI organises radiotherapy destruction codes by anatomical target site (e.g., AAA.GA.BA for brain, LCA.GA.BA for breast) and does not have a modality-level code for stereotactic radiotherapy independent of target organ; no single ICHI code captures this technique across all possible targets.
363313006 (Stimulation procedure by device)(not mapped)This SNOMED concept is a high-level category covering any device-delivered stimulation across any body target; no single assignable ICHI code exists at this level of abstraction, and device-based stimulation spans dozens of unrelated ICHI categories.
441220003 (Storage of amputated body part)(not mapped)ICHI covers reattachment and procurement of body parts/tissue but contains no code for the temporary storage or preservation of an amputated body part; this logistical/supportive act does not fit any existing ICHI category or block.
441002003 (Storage of graft tissue)(not mapped)ICHI has procurement codes (JH action) for harvesting graft tissue from donors, but no code representing the subsequent storage or banking of that tissue. The storage step is a health-service logistics activity outside ICHI's current scope.
310430006 (Stress monitoring invitation)(not mapped)A "stress monitoring invitation" is an administrative/outreach action — sending a recall or reminder for stress monitoring — and ICHI has no category representing patient invitation, recall, or reminder for clinical assessments.
135875009 (Stroke prevention)(not mapped)ICHI contains no code or block for stroke prevention or cerebrovascular risk reduction as a distinct intervention category; the concept represents a clinical goal or programme rather than a single codeable intervention.
225313009 (Supervision)(not mapped)SNOMED 225313009 represents a generic administrative/nursing act of oversight or supervision; ICHI structures interventions around specific clinical actions on defined targets and has no code corresponding to supervision as a standalone activity.
410317005 (Supplies education, guidance, and counseling)(not mapped)This SNOMED concept is a broad multi-component administrative act combining education, guidance, and counselling without a specific target; ICHI codes for education (PM), advising (PN), and counselling (PP) are always coupled to a specific functional target, so no single ICHI code captures this generic combined activity.
710819007 (Support for dignified dying)(not mapped)ICHI contains no codes related to end-of-life care, palliative support, dignified dying, or bereavement; no ICHI block covers this domain.
1231383009 (Support for use of complementary therapy)(not mapped)ICHI has individual complementary therapy technique codes but no concept representing the act of supporting or facilitating a patient's use of complementary therapies as an intervention.
223462005 (Support while performing a procedure)(not mapped)This SNOMED concept describes an adjunctive supportive role during any procedure rather than a discrete intervention; ICHI has no generic "procedural support" category.
736770009 (Surgery care)(not mapped)"Surgery care" is a high-level SNOMED administrative concept referring to the domain of surgical care management, not a specific intervention; ICHI has no corresponding administrative or care-domain category.
9667001 (Surgical avulsion)(not mapped)"Surgical avulsion" is a generic procedural technique with no body-site specificity; ICHI contains no target-independent action-only code for avulsion as a technique.
274330002 (Surgical biopsy)(not mapped)"Surgical biopsy" in SNOMED is a generic, site-unspecified concept describing open surgical tissue sampling; ICHI's biopsy action code (AD) exists only in combination with a specific anatomical target, so no target-agnostic surgical biopsy code exists.
165127005 (Surgical biopsy - administration)(not mapped)This SNOMED concept represents an administrative/contextual record of a surgical biopsy rather than the clinical intervention itself; ICHI has no administrative or encounter-management category.
274335007 (Surgical biopsy of nervous system)(not mapped)ICHI has no single code representing biopsy of the nervous system as a whole; instead it has separate codes for brain, spinal cord, cerebral meninges, cranial nerve, and peripheral nerve.
128304007 (Surgical extraction)(not mapped)"Surgical extraction" is a generic SNOMED parent concept encompassing extraction across all body sites; ICHI organises extraction codes by specific target with no NEC category or block for surgical extraction in general.
301880007 (Placement of arterial cross clamp)(not mapped)An arterial cross clamp is a temporary, intraoperative mechanical occlusion of an artery (most commonly the aorta during cardiac surgery) used as a surgical adjunct; ICHI codes for partial or endovascular occlusion of the aorta represent intentional therapeutic occlusion procedures rather than a temporary surgical clamp, and no ICHI code captures this intraoperative instrument-placement act with sufficient fidelity.
57361000087107 (Placement of bed cradle)(not mapped)A bed cradle is a simple nursing device placed over a patient's body to keep bedding off injured or sensitive limbs; ICHI does not contain any code for this type of nursing equipment placement or preventive positioning intervention.
64373007 (Placing bedrails)(not mapped)ICHI contains no code corresponding to the installation or placement of bed safety rails as a nursing/safety intervention; this highly specific procedural/environmental action is not represented anywhere in the ICHI classification.
84688002 (Placing cribguard)(not mapped)A cribguard is a dental protective appliance placed to prevent tooth damage from bruxism or cribing behaviour, and ICHI contains no code for applying such an oral protective device. Searches across dental, protective device, guard, and splint terminology all returned no usable match.
405690009 (Placing handcuffs for legal restraint)(not mapped)Applying handcuffs is a law enforcement action, not a health intervention, and ICHI does not classify individual restraint devices of this type. The only remotely related ICHI code (UBC.WB.ZZ, Restricting movement of people) is a population-level public health measure, not an individual physical restraint act.
405696003 (Placing manacles for legal restraint)(not mapped)Manacles are a law enforcement restraint device; ICHI does not contain codes for applying individual mechanical restraints of this nature. No ICHI code meaningfully corresponds to this act, even approximately.
405699005 (Placing plastic bindings for legal restraint)(not mapped)Plastic zip-tie bindings for legal restraint are a law enforcement instrument with no health intervention equivalent in ICHI. ICHI's binding-related result (a bioabsorbable surgical binding device) is an entirely different clinical context and does not correspond.
405694000 (Placing strait jacket for legal restraint)(not mapped)ICHI has no concept covering physical restraint devices applied to a person (such as a strait jacket); the closest ICHI territory is public-health legal-enforcement actions or civil protection services, but these are population-level interventions, not individual mechanical restraint applied during a clinical or custodial encounter.
21603002 (Plasma radioiron turnover rate)(not mapped)ICHI has no code for radioiron (ferrokinetic) studies; a search across radioisotope, iron turnover, hematopoietic, bone marrow scan, and radionuclide terms found no matching procedure. This is a specialised nuclear medicine measurement that falls outside ICHI's current classification scope.
29949007 (Plastic repair and revision of injury)(not mapped)ICHI does not have a generic cross-body-site code for plastic repair or revision of traumatic injury; searches across repair, wound repair, soft tissue repair, suture, and reconstruction terms found no procedure that captures this broad, body-site-agnostic SNOMED concept.
35176008 (Plastic repair and revision with revascularization)(not mapped)No single ICHI code represents a body-site-independent plastic reconstruction combined with revascularization; ICHI revascularization codes are site-specific (e.g., transmyocardial, penile), and no generic combined procedure code was found.
29940006 (Plastic revision of recent operation)(not mapped)ICHI's only "Revision" term (XG3J07) is an extension/modifier code, not a standalone assignable procedure code, and cannot be used as a primary ICHI mapping. No ICHI category code represents a generic revision of a prior plastic surgery operation without body-site or action specificity.
183471007 (Plastic surgery emergency hospital admission)(not mapped)This is an administrative encounter concept (emergency inpatient admission for plastic surgery) rather than a clinical procedure, and ICHI contains no code for specialty-specific emergency hospital admissions.
119758007 (Pleura manipulation)(not mapped)ICHI's pleura section contains specific procedural codes (biopsy, excision, pleurodesis, repair, drainage) but no generic "manipulation" code; the SNOMED concept is a broad category descriptor rather than a specific procedure, and no single assignable ICHI category adequately represents it.
10942006 (Plication)(not mapped)"Plication" in SNOMED is a high-level abstract procedure type (folding/suturing tissue to reduce its size) with no generic counterpart in ICHI. ICHI only contains body-part-specific plication codes — none covers the abstract, unspecified concept.
48640007 (Plication of fascia)(not mapped)ICHI has blocks for interventions on ligament or fascia at several anatomical sites, but the available procedure types for fascia are limited to release, division, excision, reattachment, repair, and reconstruction — plication (folding/taking tucks) of fascia is not represented as a distinct code anywhere in the classification.
405262001 (Point of care testing)(not mapped)Point-of-care testing is a service delivery concept (testing performed at or near the patient location) rather than a specific clinical procedure type, and ICHI does not contain a code for this organisational/contextual concept.
184966003 (Police request to attend)(not mapped)This SNOMED concept describes an administrative/legal act — a police authority requesting a clinician's attendance — which falls outside ICHI's scope of health interventions. ICHI contains no codes for law enforcement requests, legal notifications, or attendance obligations.
243767008 (Portal venous sampling catheter)(not mapped)The SNOMED concept refers to a specific device type (a sampling catheter used in the portal venous system), not a procedural intervention. ICHI classifies interventions, not devices or equipment; no ICHI code covers placement of a portal venous sampling catheter for diagnostic blood sampling.
225676001 (Switching on hearing aid)(not mapped)ICHI contains no code for activating or switching on a hearing aid; the hearing-related codes cover assessment, testing, advising, and education about hearing functions, while device-related codes cover installation or removal of assistive products — none represent the act of switching on an already-fitted hearing aid. This highly specific operational act (turning on a device) has no ICHI equivalent.
713148004 (Symptom management)(not mapped)ICHI has no concept corresponding to "symptom management" as a general or palliative-care activity; searches for "symptom", "palliative", "comfort", "relief", and "management" returned no usable match. ICHI organises interventions by specific body system or function target, and a cross-cutting concept like symptom management has no equivalent entry.
37989000 (T-tube clamping)(not mapped)ICHI has codes for biliary tube insertion (KCM.DL.AA), drainage (KCM.JB.AA), and irrigation (KCF.SN.AC), but no code for clamping or occluding a T-tube, which is a post-operative management step to test biliary flow prior to tube removal; this specific procedural action does not have an ICHI equivalent.
84663005 (T4 newborn screen)(not mapped)ICHI contains no codes for neonatal metabolic/hormone screening; searches for "newborn", "neonatal", "thyroid screening", "thyroxine", and related terms returned no relevant results, and no suitable code exists in the thyroid (EBA) or screening behaviour (VDB) sections for this specific diagnostic screening intervention on newborns.
234748002 (Take impression for dental restoration)(not mapped)ICHI has no code for dental impression-taking; the KAE block covers interventions on teeth (examination, restoration, implant, device application) but does not include impression procedures as a distinct clinical activity. No broader or related ICHI code captures this preparatory step without losing the essential procedural concept.
234747007 (Take impression for dental study models)(not mapped)Taking an impression for diagnostic study models is a data-gathering/assessment activity not represented in ICHI's dental codes; KAE.AE.AC (Dental examination) is the only broadly related category but does not encompass impression-taking for model fabrication.
234759006 (Take impression for maxillofacial prosthesis or appliance)(not mapped)ICHI has no maxillofacial prosthesis or impression-related code; searches for "maxillofacial", "prosthesis dental", and "orthodontic" all returned no results, and the closest available dental procedure codes (KAE.LC.AC, KAE.DN.AC) refer to the act of applying or implanting a device rather than taking an impression for one.
306986001 (Take impression for neutral zone)(not mapped)"Neutral zone" is a highly specific prosthodontic concept (the zone of minimal conflict between musculature for complete denture construction) with no analogue in ICHI; no ICHI code exists for impression-taking in any context, let alone this specialised application.
234754001 (Take impression for orthodontic appliance)(not mapped)ICHI contains no orthodontic codes at all — searches for "orthodontic" and "appliance" returned no matching procedure codes — and the procedure of taking an impression is not represented as a distinct clinical activity anywhere in the classification.
234758003 (Take impression for rebase of maxillofacial prosthesis)(not mapped)ICHI contains no codes for taking prosthetic impressions as a preparatory procedural step; there are no maxillofacial prosthetics fabrication or impression-taking codes anywhere in the classification. The concept is too granular and procedurally specific for any available ICHI category to capture with reasonable fidelity.
234757008 (Take impression for reline of maxillofacial prosthesis)(not mapped)As with the rebase impression (234758003), ICHI does not represent impression-taking steps for prosthetic reline procedures; no fabrication-preparatory or maxillofacial prosthetics impression code exists in the classification.
439264005 (Taking an impression for creation of custom speech aid prosthesis)(not mapped)ICHI does not include codes for prosthetic impression-taking procedures, whether for palatal, speech aid, or any other custom prostheses; exhaustive searching across dental, oral, speech function, and assistive product sections found no applicable fabrication-preparatory code.
24727006 (Temperature gradient studies)(not mapped)ICHI contains no code for temperature gradient studies — a diagnostic modality measuring differential temperatures across body regions (used in vascular or neurological assessment). The closest entry, ETG.AB.ZZ (Measurement of body temperature), refers to single-point thermometry and is semantically too distant to constitute a reasonable match.
278727003 (Temporal incision)(not mapped)ICHI does not have a code for a generic temporal approach incision; all incision codes are organ- or vessel-specific (e.g., MAA.FA.AA Craniotomy, BBB.FA.AA Incision of cornea), and none captures the concept of a temporal surgical access incision as a standalone procedure.
271291003 (Temporary implant radiotherapy)(not mapped)ICHI does not contain codes for brachytherapy (intracavitary or interstitial temporary implant radiotherapy); all ICHI radiotherapy codes follow an external-beam destruction pattern (e.g., "Destruction of lesion or tissue of X by radiotherapy") and do not represent the implantation and removal of a radioactive source within tissue.
73812006 (Tenotomy of stapedius)(not mapped)ICHI has no tenotomy code for the stapedius muscle or tendon; the ossicles-of-ear block (CBF) covers only stapedotomy, stapedectomy, and release of stapes, none of which is equivalent to division of the stapedius tendon. No other ICHI block covers this specific middle-ear muscle tendon procedure.
182964004 (Terminal care)(not mapped)ICHI contains no codes for palliative, terminal, end-of-life, or hospice care; an exhaustive search across multiple synonyms returned no results, and the only residual candidate (PZB.ZY.ZY, other health management encounter) is too generic and conceptually unrelated.
439863008 (Termination of therapeutic relationship)(not mapped)ICHI has no concept representing the administrative act of ending a therapeutic relationship; the closest structural concepts (discharge planning, referral to health provider, interventions on support and relationships) describe distinctly different actions and none captures the specific notion of formally closing a provider-patient therapeutic relationship.
394838008 (Test request)(not mapped)ICHI does not model the administrative/ordering act of requesting a diagnostic test; its scope covers the tests and procedures themselves rather than the ordering or requisitioning workflow, so no ICHI code is a reasonable match for this administrative concept.
78518004 (Tetracycline labeling of bone)(not mapped)ICHI contains no code for tetracycline bone labeling or bone histomorphometry; searches across bone procedures, tracer/fluorescent agents, specimen collection, and medication administration yielded no concept covering this specialized pre-biopsy fluorescent marking technique used in bone turnover assessment.
441369004 (Thawing of cryopreserved embryo)(not mapped)ICHI contains no concept for thawing, cryopreservation, or any lab-side embryo handling step; the closest embryo-related codes (NMR block) cover in-utero fetal interventions, not ex-vivo ART laboratory procedures. No reasonable mapping exists.
441222006 (Thawing of cryopreserved oocyte)(not mapped)ICHI does not represent cryopreservation or thawing of reproductive cells; the only oocyte-specific codes are retrieval procedures (NMA.JH.AB / NMA.JH.AC), and no laboratory processing or thawing action axis is present in the classification.
441198005 (Thawing of cryopreserved spermatozoa)(not mapped)ICHI has codes for sperm procurement (NGD.JH.AC) and specimen collection of sperm (NGD.AH.XE) but nothing representing ex-vivo cryogenic processing or thawing; the concept cannot be mapped.
441209003 (Thawing of cryopreserved tissue specimen from testis)(not mapped)The testis block (NGL) covers biopsy, drainage, excision, and repair of the testis in vivo, but ICHI contains no action representing thawing or any post-collection cryogenic processing of tissue specimens.
182527001 (Therapeutic aspiration procedure)(not mapped)"Therapeutic aspiration procedure" is a high-level SNOMED grouper concept covering aspiration of fluid from any body site for therapeutic purposes. ICHI encodes aspiration only at the specific anatomical target level, and no single ICHI code or block corresponds to the general, site-unspecified category this SNOMED concept represents.
179270005 (Therapeutic puncture of bone)(not mapped)ICHI contains no code for a generic therapeutic puncture of bone; bone-related percutaneous codes are limited to bone marrow biopsy (DGA.AD.AE, diagnostic) and intraosseous anaesthesia (MAG.DC.AE), neither of which captures the concept of therapeutically puncturing bone.
880071007 (Thermal pulsation treatment of meibomian gland)(not mapped)ICHI contains no code for thermal pulsation therapy (LipiFlow/iLux device treatment) of the meibomian gland; eyelid interventions in the BAA block cover surgical and injection procedures but not this thermomechanical device-based treatment for meibomian gland dysfunction.
169258005 (Thermography - hepatic region)(not mapped)ICHI liver imaging codes (KCA.BA block) enumerate CT, MRI, ultrasound, and radioisotope scan, but thermography (infrared thermal imaging) is absent as a modality; no residual hepatic imaging code accommodates this specific technique without misrepresenting the modality.
241683009 (Thermography of joint)(not mapped)ICHI contains no thermography or infrared imaging codes. The joint imaging block (BlockL6-MRJ) enumerates only arthrography, CT, and MRI modalities — no infrared/thermal imaging means code exists anywhere in the classification.
439463001 (Thermography of lower limb)(not mapped)ICHI has no thermography codes and no general lower limb imaging block; lower limb imaging codes are restricted to vascular structures (arteries/veins) only, with no coverage of thermal or infrared surface imaging of the limb as a whole.
241682004 (Thermography of scrotum)(not mapped)The scrotum interventions block (BlockL5-NGG) contains only ultrasound (NGG.BA.BJ) as an imaging code; thermography/infrared imaging of the scrotum has no corresponding ICHI code.
165095009 (Thermography of skin)(not mapped)The integumentary system sections (BlockL4-LAA, BlockL4-LZZ) contain no imaging codes whatsoever — only therapeutic, surgical, and measurement interventions — so there is no ICHI code that covers imaging or thermography of the skin.
707804004 (Thermography of whole body)(not mapped)The whole body imaging block (BlockL6-PZA) enumerates eight specific modalities (X-ray, CT, nuclear scan, SPECT, PET, MRI), none of which is infrared thermography; ICHI has no means code representing thermographic imaging anywhere in the classification.
278705007 (Thoracoabdominal incision)(not mapped)ICHI provides separate codes for thoracotomy (JCH.FA.AA) and laparotomy (PAK.FA.AA) but has no combined thoracoabdominal incision code; a thoracoabdominal incision is a distinct surgical approach crossing both body cavities simultaneously and cannot be adequately represented by either code alone.
1162782007 (Three dimensional external beam radiation therapy)(not mapped)ICHI does not classify radiotherapy by delivery technique or dimensionality; all radiotherapy codes are site-specific (e.g., destruction of lesion of breast by radiotherapy) with no code representing 3D conformal external beam radiation therapy as a modality. The only general irradiation code (PZA.GA.BA) refers to total body irradiation, which is a distinct procedure.
119977001 (Thymus destructive procedure)(not mapped)The ICHI thymus block (BlockL4-DBA) contains biopsy, incision, excision, fixation, and repair codes but no destruction or ablation code for the thymus, and no broader destruction code can be constructed from the available categories. There is no reasonable ICHI match.
287239002 (Thymus transplantation)(not mapped)The ICHI thymus block (BlockL4-DBA) has no transplantation code for the thymus, and while thymus transplantation does exist in surgical practice, ICHI does not have a coded entry for it — no DBA.KD.AA or equivalent code exists in the classification.
59911006 (Tissue autoradiography)(not mapped)Autoradiography is a laboratory/histological technique that uses radioactive tracers to produce images of tissue sections, fundamentally different from clinical nuclear imaging (scintigraphy, PET, SPECT). ICHI contains no autoradiography or equivalent laboratory imaging technique code, and the available nuclear imaging codes (BA.BE means) represent in-vivo clinical scans, not tissue-based laboratory procedures.
286585009 (Tissue disruption operation)(not mapped)ICHI organises destruction/ablation codes by specific anatomical target and no generic cross-body "tissue disruption" category exists. The SNOMED concept is a high-level grouping of procedures across all body sites, making any single body-site-specific ICHI code an inadequate match.
105036000 (Tissue preparation for drug analysis)(not mapped)ICHI does not contain a code for pre-analytical laboratory steps such as tissue preparation or specimen processing for drug analysis; its laboratory section covers specific diagnostic tests rather than preparatory techniques, and no procedural code addresses this laboratory pre-processing concept.
13283003 (Tissue processing technique)(not mapped)ICHI has no category covering histological or laboratory tissue processing techniques (e.g. fixation, embedding, sectioning); these are pre-analytical/laboratory workflow steps outside ICHI's scope of classifiable health interventions.
117007006 (Titration method)(not mapped)Titration as a laboratory analytical method or dose-adjustment technique has no direct representation in ICHI; while ICHI includes pharmacotherapy administration and prescription codes, none capture the concept of titration as a methodological approach.
252500006 (Toluidine blue staining of oral mucosa)(not mapped)ICHI has no code for vital dye staining (toluidine blue or otherwise) of the oral mucosa; this highly specific adjunctive diagnostic technique — used primarily for oral cancer screening — has no corresponding assignable category or closely related code in the classification.
234731005 (Tooth furcation plasty)(not mapped)ICHI has no code for furcation plasty or any related periodontal reshaping of the tooth furcation area; the KAE block contains only coarser dental procedures (restoration, extraction, scaling, etc.) with nothing corresponding to this specific odontoplasty technique.
241738003 (Tourniquet cuff deflation)(not mapped)ICHI contains no code for tourniquet application, cuff inflation/deflation, or limb compression device management; this highly procedural-adjunct concept has no corresponding ICHI category or closely related block.
391364009 (Toxoplasma screening test)(not mapped)ICHI contains no code for Toxoplasma or toxoplasmosis testing; the classification includes codes for screening behaviours (VDB block) and a few named infectious-disease tests (HIV, dengue, syphilis), but no general or specific code for parasitic serology such as a Toxoplasma IgG/IgM test.
119745006 (Trachea manipulation)(not mapped)The JBA block (Interventions on trachea) contains a wide range of tracheal procedures — incision, dilatation, repair, suctioning, device insertion — but no generic "manipulation of trachea" code exists; unlike joints which have explicit manipulation (PA action) codes, the trachea section has no corresponding PA-axis entry.
173076000 (Tracheopexy)(not mapped)Tracheopexy is surgical fixation or suspension of a displaced or collapsing trachea to adjacent structures; ICHI contains no fixation code for the trachea (the fixation action axis LC is not represented among trachea interventions), and no sufficiently related tracheal code exists to serve as even an approximate match.
773412008 (Traditional medicine)(not mapped)ICHI has no code or block specifically for "traditional medicine" as a category — individual modalities are coded separately (e.g., PZX.SP.AE acupuncture, PZX.SQ.AH moxibustion, PZX.SR.AH cupping), but there is no aggregating concept equivalent to the SNOMED concept of traditional/complementary/alternative medicine as a practice type. No satisfactory match exists at any level of specificity.
428632005 (Transportation request)(not mapped)A transportation request is an administrative act (ordering or requesting transport) rather than a health intervention, and ICHI has no code representing service requests or administrative orders of this nature. No ICHI category exists for request or ordering acts.
359667002 (Transverse incision)(not mapped)ICHI codes incisions by anatomical target (e.g., "Incision of artery of upper limb"), not by the geometric orientation or technique of the cut. "Transverse incision" is a procedural technique modifier that ICHI captures through the means axis, not as a standalone intervention, so no single ICHI assignable code corresponds to this concept.
183463008 (Trauma emergency hospital admission)(not mapped)ICHI classifies health interventions (clinical procedures, rehabilitation, public health actions) but does not include administrative or care-pathway events such as hospital admissions or triage processes. No ICHI code for inpatient admission or emergency presentation was found.
395057007 (Trichomonas screening test)(not mapped)No ICHI code for Trichomonas vaginalis detection or screening exists — searches for trichomonas, protozoa, parasite, vaginal infection test, microscopy, and STI screening all yielded no relevant match. ICHI's essential laboratory test extension codes cover only a limited set of pathogens and do not include Trichomonas.
119601001 (Trunk manipulation)(not mapped)ICHI contains no assignable category code for a general manipulation of the trunk; spinal manipulation codes exist for specific vertebral levels (e.g., MBG.PA.AH for thoracic spine), but these are anatomically specific and do not cover the SNOMED concept of trunk manipulation as a broad grouping. No reasonably equivalent ICHI code was identified.
386480001 (Truth telling)(not mapped)"Truth telling" (the clinical ethics act of disclosing diagnosis or prognosis to a patient) has no corresponding ICHI code; ICHI does not classify ethical communication acts such as informed disclosure or breaking bad news, and no approximating code for provider-to-patient diagnostic disclosure was found across counselling, interviewing, or information categories.
60519005 (Turbidity test, quantitative)(not mapped)ICHI contains no code for turbidity testing or any equivalent optical/photometric specimen analysis method; the classification does not cover this type of laboratory bench test at all, and no broader analytical or urinalysis code captures the specific concept of a quantitative turbidity measurement.
225672004 (Turning off hearing aid)(not mapped)ICHI does not classify the act of switching off or deactivating an external hearing aid; the closest ear-device codes (CBA.SM.AC "Management of prosthetic device of the middle ear" and CCB.SM.AH "Management of cochlear prosthetic device") refer to implanted devices, not externally worn hearing aids, and no code addresses their simple on/off operation.
49913004 (Ultrashort wave diathermy)(not mapped)ICHI does not contain a dedicated code for diathermy or shortwave therapy as a therapeutic modality; the hyperthermy codes (e.g., AXA.SD.BQ, MRM.SD.BQ) represent hyperthermy applied to a specific anatomical target or for pain, whereas ultrashort wave diathermy is a modality-specific physical therapy technique with no equivalent target-independent ICHI representation.
61593002 (Ultrasonic guidance procedure)(not mapped)ICHI treats imaging guidance as an extension code (XG0MQ2 "With image guidance") appended to a substantive intervention code, rather than as a standalone procedure; there is no assignable ICHI category code representing ultrasonic guidance as a procedure in its own right.
24135002 (Ultrasonography of total body)(not mapped)The ICHI whole-body imaging block (PZA) includes X-ray, CT, radioisotope scan, PET, and MRI of whole body, but conspicuously lacks a whole-body ultrasound code (PZA.BA.BJ does not exist), leaving no reasonable ICHI match for total-body ultrasonography.
58013000 (Unbridling of artery of limb)(not mapped)"Unbridling" of an artery (surgical release of fibrous or muscular bands compressing an artery, such as popliteal artery entrapment release) has no corresponding ICHI code; the limb artery blocks contain incision, endarterectomy, bypass, and reconstruction codes but none that capture the specific concept of releasing extrinsic compression on an artery.
32989007 (Unsatisfactory clinical laboratory specimen identified)(not mapped)ICHI covers specimen collection procedures but does not include quality assessment, rejection, or identification of unsatisfactory specimens; this SNOMED concept describes a finding/event in the pre-analytical laboratory phase, for which no corresponding ICHI intervention code exists.
241734001 (Upper tourniquet cuff inflation)(not mapped)ICHI contains no codes for tourniquet application, cuff inflation, or limb exsanguination; this is an adjunctive operative technique/device application without a corresponding ICHI category, and no broader proxy code captures the concept without severe distortion.
183468004 (Urology emergency hospital admission)(not mapped)ICHI classifies health interventions and does not include administrative or logistical acts such as hospital admission or care pathway routing. No equivalent or even approximate ICHI code exists for an emergency admission event.
169437002 (US therapy - skin lesion)(not mapped)ICHI has no code for ultrasound (US) as a therapeutic modality applied to the skin; the skin section covers only surgical, phototherapy, biopsy, excision, and device management interventions, with no energy-delivery-via-ultrasound equivalent. The closest concept (phototherapy to skin) uses light rather than sound waves and represents a different physical modality.
56731000087101 (Use of half-door for restraint)(not mapped)ICHI has no code for environmental or physical containment measures such as half-doors or similar passive restraint devices; the immobilisation codes relate only to orthopaedic external fixation, and no environmental modification or behavioural-containment category covers this specific nursing/safety intervention.
83506002 (Uterine contraction monitor removal)(not mapped)ICHI does not contain a code for removing a uterine contraction monitoring device; the fetal/uterine section includes only internal fetal monitoring and ultrasound-based assessments, and the removal-of-internal-device action does not appear to be combined with any uterine or obstetric target in the classification.
699122005 (Vascular surgery emergency hospital admission)(not mapped)This SNOMED concept describes an administrative/organisational act (emergency hospital admission for vascular surgery) rather than a clinical intervention; ICHI does not classify hospital admissions, referral pathways, or encounter types.
385757000 (Venous catheter care)(not mapped)ICHI does not contain a procedure code for catheter care, maintenance, or management; the available catheter-related entries are extension/device codes without assignable procedure titles.
1304134003 (Verification of identity by direct questioning)(not mapped)ICHI does not contain a code for patient identity verification through direct questioning; this is an administrative/safety procedure not represented in the ICHI classification.
1304133009 (Verification of identity prior to procedure)(not mapped)ICHI does not classify perioperative administrative safety steps; patient identity verification prior to a procedure is a pre-procedural workflow activity with no corresponding ICHI intervention code.
1304132004 (Verification of identity using information from guardian)(not mapped)This is a specific method variant of pre-procedural identity verification (using a guardian as the information source), which is an administrative patient-safety activity with no representation in ICHI's clinical intervention taxonomy.
1304131006 (Verification of identity using information on identification band)(not mapped)This concept describes a specific modality of patient identity checking (reading a wristband/ID band), which is an administrative safety workflow step not captured in the ICHI classification.
372053005 (Verification of operative procedure)(not mapped)Confirming that the correct operative procedure is planned (a core WHO Surgical Safety Checklist step) is an administrative/patient-safety act that ICHI does not represent as a classifiable health intervention.
713089003 (Verification of presence of corrective device)(not mapped)Checking that a corrective device (e.g., splint, orthosis, prosthesis) is present is a pre-procedural administrative check rather than a clinical intervention, and ICHI has no code for this type of safety verification.
409056005 (Verification of surgical site and laterality)(not mapped)ICHI does not contain a code for pre-procedural safety checks such as confirming the operative site and laterality; this is a perioperative administrative/safety step rather than a health intervention as classified by ICHI.
370862004 (Verifying presence of prosthetics)(not mapped)ICHI does not classify pre-procedural checks for the presence of implanted or external prosthetic devices; only procedural codes for inserting, replacing, or removing prosthetics exist, none matching this safety-screening concept.
792798008 (Video assisted thoracoscopy for control of hemorrhage)(not mapped)ICHI contains thoracoscopic procedure codes but does not have a general haemostasis or hemorrhage-control code for the thoracic cavity or lung that captures a thoracoscopy performed specifically to control hemorrhage in a non-organ-specific sense.
169418006 (Visible light therapy)(not mapped)All ICHI phototherapy codes are skin/subcutaneous tissue-targeted dermatological procedures and do not represent visible light therapy as a distinct clinical modality; no ICHI code adequately captures this intervention.
135848002 (Voluntary admission)(not mapped)ICHI does not include administrative/legal procedures such as voluntary hospital admission; ICHI focuses on clinical, rehabilitative, and public health interventions rather than administrative care pathways.
55034008 (Ward laboratory procedure, screening)(not mapped)ICHI contains only two laboratory-related codes (a block for essential laboratory tests and a single serological test code), neither of which represents a generic point-of-care or ward-based laboratory screening procedure; the SNOMED concept describes a broad procedural category with no sufficiently close ICHI equivalent.
225255002 (Washing cervical cap)(not mapped)ICHI does not include codes for cleaning, reprocessing, or maintenance of barrier contraceptive devices such as the cervical cap; no ICHI code at any level of granularity captures this patient self-care or device-hygiene activity.
281183006 (Wax-up of trial maxillofacial prosthesis)(not mapped)ICHI contains no code for fabrication, wax-up, or trial fitting of a maxillofacial/craniofacial prosthesis; the assistive-product installation codes (e.g., PAB.DP.AH) cover fitting completed devices, not the prosthesis wax-up/trial stage, which is a dental-laboratory or prosthodontic procedural step not represented in ICHI.
1237157002 (Waxing up of teeth on study model)(not mapped)ICHI has no code covering dental laboratory procedures such as waxing up teeth on a study model; the teeth interventions block (KAE) addresses clinical dental procedures on patients (restoration, extraction, implantation, etc.) and does not include diagnostic or planning model fabrication work.
185465003 (Weekend visit)(not mapped)A "weekend visit" is a temporary therapeutic home leave granted to an inpatient, which is an administrative/care-pathway concept rather than a clinical intervention; no ICHI code covers temporary hospital passes, home visits, or equivalent concepts, and searches for visit, leave, discharge, and home produced no relevant match.
37519000 (Whole organ section preparation for special studies)(not mapped)ICHI does not contain codes for gross pathology specimen preparation techniques such as whole organ sectioning; this is a laboratory/pathology workflow step rather than a health intervention as classified by ICHI, and no sufficiently close code exists.
711420002 (X-ray consultation)(not mapped)ICHI classifies X-ray procedures by specific anatomical target (e.g., X-ray of skull, X-ray of lung) but has no concept for a consultation about or review/interpretation of an X-ray image as a standalone act. The consultation dimension has no representation in ICHI.
431743005 (Yttrium 90 somatostatin analog therapy)(not mapped)ICHI contains radioactive iodine destruction of thyroid (EBA.GA.BE) and external radiotherapy codes but has no code for peptide receptor radionuclide therapy (PRRT) using a radiolabelled somatostatin analog such as Y-90 DOTATATE/DOTATOC. No sufficiently close target-action-means combination exists in ICHI for this systemic targeted radionuclide treatment.
408268003 (24 hour Bence-Jones screening test)(not mapped)ICHI contains no code for Bence-Jones protein testing, urinary protein electrophoresis, or any analogous paraprotein/immunoglobulin urine assay. The Essential Laboratory Tests block (XG1) does not include this test, and no urinary chemistry code at sufficient specificity exists to represent this haematology screening procedure.
225310007 (24 hour supervision)(not mapped)ICHI has no code that captures round-the-clock patient supervision or continuous observation as a clinical intervention; the closest ICHI constructs (observation actions like AM, monitoring codes) are tied to specific body functions or clinical parameters rather than representing general time-based patient surveillance.
444660008 (70-gene expression profile assay)(not mapped)ICHI contains no codes for molecular/genomic assays such as multi-gene expression profiling (e.g. MammaPrint). The classification does not cover laboratory diagnostic tests of this type, so no reasonable ICHI match exists.
108193009 (Abdomen destructive procedure)(not mapped)The PAK (Interventions on abdomen, not otherwise specified) block has no destruction-action code, and no other ICHI block captures a generic destructive procedure of the abdomen as a category. ICHI does have organ-specific destruction codes but nothing that maps to this high-level topographical grouping concept.
179225002 (Abduction traction)(not mapped)Abduction traction is a specific orthopaedic technique applying traction force in an abduction direction to a limb (most commonly the hip or shoulder) for fracture management or joint reduction; ICHI contains traction only for the spine (MBZ.LC.AE) and no analogous limb traction codes, so no reasonable ICHI match exists for this concept.
229432006 (Accessory mobilization of the larynx)(not mapped)ICHI contains no mobilisation code for the larynx; all larynx codes (JAN block) cover surgical/endoscopic procedures such as incision, repair, excision, and dilatation, and the series of joint mobilisation codes (PB action) does not extend to laryngeal structures. Accessory mobilization of the larynx is a manual physiotherapy technique on laryngeal cartilages for which ICHI has no assignable category.
104635009 (Acetoacetic acid measurement, cerebrospinal fluid)(not mapped)ICHI does not contain codes for specific analyte measurements in cerebrospinal fluid; the classification lacks any category representing biochemical quantitation of ketone bodies (such as acetoacetate) in CSF. The closest extension codes (XA1N55 "Cerebrospinal fluid" and XG0S88 "Ketones") are supplementary extension codes, not standalone assignable intervention codes, and no procedural category combining them exists.
406792001 (Acid phosphatase stain method)(not mapped)ICHI has no category for cytochemical or histochemical staining methods; the only phosphatase-related code found is XG1EQ9 "Alkaline phosphatase," which is an extension/supplementary code for a different enzyme and a different assay type. No assignable ICHI intervention code represents acid phosphatase staining as a laboratory technique.
104149001 (Acidified serum lysis test, RBC)(not mapped)The Ham test (acidified serum lysis test) is a highly specific haematology diagnostic assay for paroxysmal nocturnal haemoglobinuria; ICHI contains no diagnostic laboratory analysis codes — only blood specimen collection (DIA.AH.XA) and blood product interventions — so no reasonable ICHI match exists.
413433006 (Active monitoring)(not mapped)"Active monitoring" (also called watchful waiting) is a clinical management strategy of deliberate observation without treatment, and no ICHI code captures this general concept — ICHI's monitoring codes are all organ/system-specific (e.g., monitoring of respiration, monitoring of brain) and do not represent a generic, non-intervention patient management approach.
424313000 (Active surveillance)(not mapped)"Active surveillance" in clinical use (e.g., for low-risk prostate cancer) denotes a structured deferred-treatment strategy with scheduled monitoring — a concept absent from ICHI; all ICHI surveillance codes fall under public health environmental or population surveillance (VC axis), which is categorically different.
1300121009 (Acute phase rehabilitation)(not mapped)ICHI does not have a code representing rehabilitation specifically in the acute phase of illness or injury; XG4691 ("Rehabilitation and Habilitation") is an extension code rather than a standalone assignable intervention, and no assignable category captures the concept of acute-phase rehabilitation as a distinct service type.
228594004 (Adaptive and compensatory techniques)(not mapped)ICHI does not contain a code representing the rehabilitation concept of teaching or applying adaptive and compensatory techniques as a category of intervention; available training codes in the S-block are tied to specific activity domains and do not capture this cross-cutting therapeutic approach.
119961002 (Adenoid repair)(not mapped)The ICHI adenoid block (BlockL5-DAB) contains only biopsy, excision, foreign body removal, haemorrhage control, and adenoidectomy codes — no repair or reconstruction category exists for the adenoid. The DAB target + MK (repair) action combination is not a valid ICHI code, and no other ICHI code reasonably captures adenoid repair.
711133000 (Administration of fluid therapy)(not mapped)ICHI contains no code specifically representing administration of IV or oral fluid therapy (hydration/volume replacement); the pharmacotherapy codes (PZA.DB.xx) refer to drug/medicament administration, not fluid resuscitation or hydration, and no blood-product or electrolyte-balance code covers this concept.
182943003 (Administration of prophylactic iodine for iodine deficiency goiter)(not mapped)ICHI has no code representing iodine supplementation or iodine administration for deficiency prevention — the only iodine-related code (EBA.GA.BE) is for radioactive iodine thyroid ablation, which is a completely different intervention; PZA.DB.AZ is too generic to represent a specific mineral supplementation for a defined deficiency condition.
439728005 (Administration of radiopharmaceutical agent via intraarterial route)(not mapped)ICHI has no code for intraarterial delivery of a radiopharmaceutical agent; the pharmacotherapy block (PZA.DB) does not include an intraarterial route means code, and no other ICHI category captures this specific combination of radiopharmaceutical substance with intraarterial delivery.
712489002 (Administration of sedative via rectal route)(not mapped)ICHI contains no code for rectal drug administration as a standalone intervention, and there is no category specifically representing sedative or CNS-depressant administration; the rectal route and sedative drug class together have no plausible ICHI equivalent.
297279009 (Administration of steroid)(not mapped)ICHI does not contain a generic code for steroid or corticosteroid administration; the endocrine function block (ETK) covers only assessment and counselling of endocrine functions, and no drug administration code in ICHI captures steroids as a class across all routes and indications.
1231812002 (Administration of substance with alpha-1 adrenergic receptor antagonist mechanism of action)(not mapped)ICHI does not classify drug administration by pharmacological mechanism of action. No code exists for alpha-1 adrenergic receptor antagonists or their administration, and the general "providing medications" code (UAC.RD.ZZ) is a supply/logistics concept rather than a clinical administration act.
432955007 (Administration of sulfonylurea)(not mapped)ICHI does not contain codes for specific drug class administration such as sulfonylureas. No code for antidiabetic agent administration exists, and the available "providing medications" (UAC.RD.ZZ) describes logistics of medication supply rather than clinical administration of a therapeutic agent.
37750001 (Administration of tranquilizer)(not mapped)ICHI does not contain codes for administration of psychotropic drugs, tranquilizers, anxiolytics, or antipsychotics. No searched synonym (anxiolytic, antipsychotic, sedative, hypnotic, psychotropic) yielded any relevant result in the ICHI hierarchy.
1351996009 (Adolescent and young adult oncology care)(not mapped)ICHI has no codes for oncology care programs, age-specific care services, or multidisciplinary cancer management. This SNOMED concept describes a specialized care service type that falls outside ICHI's coded scope.
254308004 (Advancement of pedicle graft)(not mapped)ICHI has no code for the advancement of a pedicle graft as a distinct procedure; XG9JE8 is merely an extension code identifying "Pedicle flap" as a supplementary descriptor, not a standalone intervention code, and no category code captures the act of advancing a pedicle graft to a recipient site.
359821004 (Agglutination assay)(not mapped)ICHI contains only two disease-specific agglutination tests (T. pallidum haemagglutination and particle agglutination), neither of which represents the generic, technique-level concept of an agglutination assay. There is no ICHI code for agglutination as a general laboratory method.
359818001 (Agglutination procedure)(not mapped)Like "Agglutination assay," this SNOMED concept describes the general immunological procedure of agglutination, for which ICHI has no corresponding generic code. The only ICHI agglutination entries are narrow disease-specific tests (T. pallidum), making any match misleading.
406793006 (Albert's stain method)(not mapped)Albert's stain is a specific histochemical staining technique used for demonstrating metachromatic granules (e.g., in Corynebacterium diphtheriae). ICHI does not include named staining methods or specific histochemical techniques — the classification operates at a higher procedural level and contains no staining or laboratory technique codes of this specificity.
117036006 (Alcian blue stain method)(not mapped)Alcian blue is a specific dye used histochemically to stain acidic mucopolysaccharides/glycosaminoglycans. ICHI does not enumerate named staining techniques; even its extension code XG30Q5 (Histopathology) is a coarse grouping that does not meaningfully capture a specific named stain method.
406794000 (Alcohol soluble nigrosine stain method)(not mapped)ICHI does not classify laboratory staining methods or histological techniques; nigrosine staining is a specific laboratory dye procedure that falls entirely outside ICHI's scope of health interventions (which covers clinical procedures, rehabilitation, and public health actions rather than bench-level laboratory methods).
406795004 (Alizarin blue S stain method)(not mapped)ICHI does not classify individual histochemical staining reagent techniques; specific dye-based staining methods (here a triarylmethane dye applied to tissue sections) operate at a granularity far below what ICHI captures, and no ICHI code — including the broad XG30Q5 Histopathology extension code — constitutes a reasonable match.
406796003 (Alizarin cyanine green stain method)(not mapped)As with all Alizarin stain variants, ICHI contains no codes for specific histochemical staining techniques; exhaustive searches on staining, dye, histopathology, histochemical, special stain, and related terms returned no usable ICHI category, confirming there is no reasonable match.
406797007 (Alizarin red S stain method)(not mapped)Alizarin red S is a specific anthraquinone dye used to detect calcium in tissue — a sub-technique level of specificity that ICHI does not represent; no ICHI code covers this procedure or its class of histochemical staining methods.
406798002 (Alizarin yellow GG stain method)(not mapped)ICHI does not classify individual staining reagent methods regardless of the dye compound involved; this azo dye staining technique has no corresponding ICHI category, block, or extension code at any level of the hierarchy.
406799005 (Alizarin yellow R stain method)(not mapped)Alizarin yellow R is another azo dye variant in the same family of histochemical staining procedures, none of which are represented in ICHI; the classification simply does not operate at the level of individual laboratory staining reagent techniques.
277449007 (Alkalinization regime)(not mapped)ICHI contains no code for urinary or systemic alkalinization or acid-base manipulation regimens; the closest candidates (electrolyte/water balance functions under ETE, or pharmacotherapy administration under PZA.DB.AZ) each capture only one dimension of what is inherently a multi-component treatment protocol. No single ICHI code represents the concept of an alkalinization regimen as such.
426984008 (Allotransplantation of thymus gland)(not mapped)The thymus block (DBA) contains codes only for biopsy, excision, incision, fixation, and repair — there is no transplantation or grafting code for the thymus in ICHI, and no transplant code appears elsewhere in the classification for this organ.
66181001 (Alpha globulin gene analysis)(not mapped)ICHI does not contain codes for molecular genetic analyses such as gene-level sequencing or globulin gene testing; its essential laboratory test extension codes cover common clinical tests but not targeted gene analysis of protein families.
397630008 (Alpha-1-antitrypsin phenotype determination)(not mapped)ICHI has no code for protein phenotyping or isoelectric focusing procedures such as alpha-1-antitrypsin phenotype determination; its laboratory extension block is limited to essential global-health tests and does not include specialist biochemical phenotyping assays.
313128003 (Alternating current therapy)(not mapped)ICHI's electrical stimulation codes are targeted to specific body targets or goals (pain, muscle, gait, brain) and none covers the use of alternating current as a general or unspecified therapeutic modality; there is no NEC/NOS electrical therapy category that would serve as a reasonable broader match.
1172397006 (Alveolar ridge preservation)(not mapped)Alveolar ridge preservation is a dental procedure performed after tooth extraction to maintain bone volume in the jaw ridge, but ICHI has no codes covering dental alveolar/socket bone grafting or ridge preservation; the dental section lacks this specific procedure and no general bone-preservation code exists.
440404000 (Ambulatory continuous glucose monitoring of interstitial tissue fluid with sensor placement)(not mapped)ICHI does not have an assignable code capturing continuous ambulatory glucose monitoring via an interstitial subcutaneous sensor; the closest reference appears only as an extension/device code without a corresponding intervention category code, and no monitoring code exists that captures the combined sensor placement plus continuous interstitial glucose measurement.
54483009 (Amputation education)(not mapped)ICHI does not contain any code specifically for education about amputation or stump/residual limb management; the education codes present are organised by body function or behaviour target, and none correspond to post-amputation or amputee patient education as a discrete concept.
121328002 (Anabolic steroid identification)(not mapped)ICHI contains no codes for drug identification, toxicological testing, or anabolic steroid screening; the Essential Laboratory Tests block is limited to a narrow set of priority tests and does not include forensic or performance-enhancing substance assays.
737855007 (Anaphylaxis care)(not mapped)ICHI has no code or block dedicated to the clinical management of anaphylaxis or acute allergic reactions; searches across anaphylaxis, hypersensitivity, immune reaction, adverse reaction, acute care, and emergency returned no relevant results, and no body-system block addresses this cross-cutting acute condition management scenario.
86386006 (Anchoring of tendon of biceps)(not mapped)ICHI has no assignable procedure code for the biceps tendon — the shoulder tendon block (MDT) contains only rotator cuff repair codes, and there is no code representing tenodesis or anchoring of the biceps tendon specifically.
15367004 (Ancillary service audit)(not mapped)ICHI does not contain codes for administrative or quality-assurance activities such as health service audits; its scope covers clinical, rehabilitative, and public health interventions rather than organisational or managerial processes.
413534002 (Anesthesia machine check)(not mapped)ICHI contains no concept for checking, inspecting, or verifying an anaesthesia machine or any other medical equipment; this preparatory safety activity falls entirely outside ICHI's scope.
243062008 (Anesthetic procedure education)(not mapped)ICHI's education action codes (PM) are organised around body functions, stoma types, and rehabilitation topics — there is no code for education about an anaesthetic procedure specifically, and no sufficiently close surrogate exists in the classification.
25469001 (Anion gap measurement)(not mapped)ICHI does not contain codes for individual laboratory analyte measurements such as the anion gap; the closest ICHI concepts are structurally incompatible — the SNOMED concept is a calculated laboratory parameter derived from serum electrolytes, not a clinical assessment of function or a specimen collection act.
121330000 (Antidepressant identification)(not mapped)ICHI contains no code for drug-class-specific identification or laboratory detection of antidepressants (e.g., therapeutic drug monitoring, toxicology screens). No general "drug identification" or "substance assay" category exists in ICHI that could serve as even an approximate match.
117639000 (Antidiuretic identification)(not mapped)ICHI has no code for the identification or measurement of antidiuretic hormone (ADH/vasopressin); searches across endocrine, metabolic, and haematological function blocks returned only generic assessment and education codes, none of which represent a specific hormone assay.
121331001 (Antipsychotic identification)(not mapped)ICHI contains no code for identifying, screening, or testing for a specific drug class such as antipsychotics; the essential laboratory tests block covers only a limited curated set of priority tests with no drug-class identification entries, and the broader ICHI hierarchy has no therapeutic drug monitoring or drug identification category.
359779009 (Antistreptococcal hyaluronidase titer)(not mapped)ICHI has no code for serological antibody titer testing against streptococcal enzymes; the essential laboratory tests block covers only priority infectious-disease tests (HIV, hepatitis, malaria, etc.) and no streptococcal or antihyaluronidase serology entry exists anywhere in the ICHI hierarchy.
119776000 (Aorta closure)(not mapped)ICHI lacks any code for closing or suturing an aortotomy; available aortic codes cover incision, occlusion, excision, and reconstruction but none represent closure of a surgical wound in the aorta wall.
412985006 (Apolipoprotein E genotype determination)(not mapped)ICHI does not contain codes for molecular genetic testing or specific genotyping assays; the essential laboratory tests block (XG1) covers a limited set of infectious disease and basic chemistry tests only, with no coverage of lipid-related genetic analysis. No reasonable ICHI mapping exists for ApoE genotyping.
250692007 (Apolipoprotein E phenotype determination)(not mapped)Apolipoprotein E phenotyping (typically performed by isoelectric focusing or immunoblotting) is a specialised protein isoform assay not represented in ICHI; neither the laboratory tests block nor any other section contains codes for lipoprotein or apolipoprotein analysis.
37966008 (Application of heat lamp to perineum)(not mapped)ICHI has no code for heat lamp (infrared lamp) therapy, and the perineum block contains no thermal or physical modality interventions — only surgical, diagnostic, and injection procedures. The phototherapy codes that do exist are for ultraviolet/light-based skin treatments, not infrared heat lamp application, making any match semantically misleading.
257757005 (Application of hemoclips)(not mapped)ICHI does not represent haemostatic clip application as a standalone or general procedure — the only haemostasis codes present are site-specific endoscopic or organ-specific entries (bronchus, bladder, prostate). Hemoclip application is a device-based haemostatic technique that lacks a corresponding general ICHI category.
80013005 (Application of mechanical traction on skin)(not mapped)ICHI has no code specifically for skin (adhesive) traction — a technique where adhesive straps applied to skin transmit a traction force to a limb segment; the available immobilisation device codes are bone/joint-targeted rather than skin-targeted, and no code captures the skin-surface traction mechanism.
449399005 (Application of personal protective equipment)(not mapped)ICHI classifies interventions directed at patients or populations, and no code exists for donning PPE as a healthcare worker safety measure. This concept represents an occupational/infection-control action for the provider rather than a health intervention on a patient, placing it outside the ICHI scope.
225170008 (Applying hemostatic swab)(not mapped)ICHI has no code for surface application of a hemostatic agent via swab; haemostasis codes in ICHI are site-specific endoscopic or surgical procedures (e.g. gastric, bronchial), and no general topical hemostatic application code exists.
427464008 (Arginine vasopressin response to hypertonic saline test)(not mapped)This is a highly specific neuroendocrine provocation test (measuring ADH/AVP secretory response to a hypertonic saline stimulus) that has no counterpart in ICHI; the classification contains no codes for vasopressin, hypertonic saline, osmolality, or equivalent dynamic endocrine stimulation tests.
121332008 (Aromatic solvent identification)(not mapped)ICHI contains no code for identification or analysis of aromatic solvents or chemical substances in a diagnostic/toxicological context; the essential laboratory tests block covers specific clinical biomarkers and does not include chemical substance identification procedures of this type.
699126008 (Arterial catheter care assessment)(not mapped)ICHI does not contain codes for post-insertion nursing assessment of arterial catheters; this concept represents a care/monitoring activity around an indwelling arterial line that falls outside ICHI's assignable code coverage.
716754001 (Arterial catheter care management)(not mapped)Like its assessment counterpart, arterial catheter care management is a nursing/care management activity for an existing arterial line that has no corresponding ICHI code; ICHI covers device insertion and replacement but not ongoing catheter maintenance or management activities.
121333003 (Asbestos identification)(not mapped)ICHI contains no code for identifying asbestos or similar mineral fibre hazards; the environmental blocks (e.g. UBT land pollution, UBL indoor air) only cover assessment, remediation, and surveillance at a population/environmental level, not a laboratory or occupational identification procedure for a specific substance like asbestos.
14766002 (Aspiration)(not mapped)"Aspiration" as a SNOMED concept is a high-level category covering any aspiration act regardless of body site, which does not map to any single ICHI code; ICHI codes aspiration at the specific body-site level (e.g. thyroid, orbit, gallbladder) and no single ICHI code captures the generic, site-unspecified notion of aspiration.
386519006 (Aspiration precautions)(not mapped)ICHI contains no code representing preventive nursing precautions against pulmonary aspiration (positioning, feeding precautions, oral care protocols); the swallowing block (KTC) covers assessment and training of swallowing function but does not encompass the multi-component safety precaution bundle that this SNOMED concept describes.
430277005 (Aspiration using fluoroscopic guidance)(not mapped)This SNOMED concept is a technique modifier (aspiration performed under fluoroscopic guidance) rather than a complete procedure on a defined body part; ICHI always requires a specific target + action + means triad and has no generic body-site-agnostic "aspiration with fluoroscopic guidance" category.
432557008 (Aspiration using ultrasound guidance)(not mapped)Like its fluoroscopic counterpart, this concept is a procedural technique qualifier (aspiration guided by ultrasound) without a specified target organ; ICHI encodes ultrasound guidance within the Means axis of body-part-specific codes but has no stand-alone generic aspiration-under-ultrasound category applicable across all targets.
448464001 (Assessment of airway device cuff pressure)(not mapped)ICHI contains codes for insertion, suctioning, and removal of endotracheal tubes (JBA block) and a general respiratory pressure measurement, but no code exists for checking or measuring cuff inflation pressure of an airway device. This is a specific equipment safety check that falls outside ICHI's current classification granularity.
58861000087101 (Assessment of family history using genogram)(not mapped)ICHI contains no code for taking or analysing a family history, nor for the genogram method specifically; the nearest candidates address functional or social support dimensions of family rather than hereditary/genealogical history-taking as a clinical documentation technique.
473204006 (Assessment of raised intracranial pressure)(not mapped)ICHI contains intracranial monitoring and imaging procedural codes but none that map to a clinical assessment of raised intracranial pressure as a pathophysiological state; the available intracranial codes are device placements or imaging modalities rather than assessments, so no reasonable ICHI match exists.
719295003 (Assessment using Centor criteria)(not mapped)Centor criteria constitute a clinical decision-support scoring tool for estimating group A streptococcal pharyngitis probability; ICHI has no code for probabilistic infection risk scoring tools or clinical decision rules, and no pharyngitis-specific assessment code exists in the classification.
763007002 (Assessment using CHADS2 (congestive heart failure, hypertension, age 75 years or older, diabetes mellitus and previous stroke or transient ischemic attack) score)(not mapped)CHADS2 is a structured thromboembolic risk stratification score for atrial fibrillation patients; ICHI contains no code for clinical risk scoring tools of this type, and the nearest cardiovascular assessment code (HTB.AA.ZZ) concerns heart function assessment rather than multi-factorial stroke risk calculation.
763112004 (Assessment using Footwear Suitability Scale)(not mapped)ICHI contains no code for assessing the suitability or fit of footwear; the only footwear-related entry is "Therapeutic footwear" (a treatment, not an assessment), and no equivalent assessment target or instrument exists in the classification.
1352017001 (Assessment using Paediatric Index of Mortality 3)(not mapped)The Paediatric Index of Mortality 3 (PIM3) is a paediatric ICU mortality probability scoring tool — a prognostic/risk-stratification instrument. ICHI has no dedicated code or general prognostic/mortality scoring category; the available assessment codes target specific body systems or functions rather than multi-system mortality prediction, so no reasonable ICHI mapping exists.
865913006 (Assessment using Preparedness for Caregiving Scale)(not mapped)The Preparedness for Caregiving Scale assesses a family caregiver's readiness to provide care — a caregiver-facing construct with no corresponding ICHI target axis covering caregiver preparedness or caregiver role assessment. ICHI does not contain a code for assessing the caregiver's own functional readiness to deliver care.
1351238004 (Assessment using Revised Jones Criteria)(not mapped)The Revised Jones Criteria are a multi-system diagnostic decision framework applied by a clinician to diagnose acute rheumatic fever, incorporating cardiac, articular, neurological, and dermatological criteria simultaneously; no single ICHI code captures this multi-system diagnostic evaluation, and reducing it to a cardiac-only code would be semantically misleading.
1290286006 (Assessment using Risk Score for Transport Patients)(not mapped)ICHI has no code covering pre-transport clinical risk scoring or stability assessment prior to patient transfer; the classification does not include codes for logistical or transport-readiness risk stratification tools, and no existing ICHI category is a reasonable proxy for this intervention.
714346003 (Assessment using Session Rating Scale)(not mapped)The Session Rating Scale is a patient-reported measure of therapeutic alliance (relationship quality, goal agreement, approach fit, and overall session satisfaction), which is an evaluation of the therapeutic process rather than any body function, body structure, activity, or participation domain covered by ICHI. No ICHI code addresses therapeutic alliance, session feedback, or patient-rated treatment engagement.
372132004 (Surgical procedure by RN first assist)(not mapped)This SNOMED concept describes a role-based qualifier (procedure performed with a registered nurse acting as first assistant) rather than a distinct clinical intervention; ICHI classifies interventions by what is done to the patient, not by professional role of an assistant.
107784002 (Surgical procedure on lower extremity)(not mapped)ICHI does not have a single grouper code covering the entire lower extremity for surgical procedures; interventions are organized by specific anatomical sub-region (thigh, knee, lower leg, foot, lower limb vessels, etc.) and the block-level groupers (e.g., MQS) are not assignable codes and only cover musculoskeletal NEC interventions.
66284001 (Surgical repair and revision of pouch)(not mapped)ICHI contains no code for repair or revision of a pouch (e.g., ileal reservoir/J-pouch); neither "pouch", "reservoir", nor "ileal pouch" return any results, and no action + target combination in the digestive system blocks covers this concept.
13707001 (Surgical repair and revision of stoma)(not mapped)ICHI contains codes for creation of stomas (colostomy KBP.LI.AA, ileostomy KBK.LI.AA) but no code for repair or revision of an existing stoma; searches for "stoma repair", "stoma revision", "colostomy revision", and "ileostomy revision" all return no results.
188383006 (Surgical repair of lower extremity)(not mapped)This SNOMED concept is a broad grouping of all surgical repair procedures on the lower extremity; ICHI organises lower limb interventions by specific tissue type and anatomical sub-region (bone, joint, vessel, tendon, etc.) with no single code or block that covers all surgical repairs of the entire lower limb.
363319005 (Surgical repair of upper extremity)(not mapped)This SNOMED concept broadly groups all surgical repairs of the upper extremity; ICHI has no equivalent umbrella code, instead distributing upper limb repair procedures across multiple tissue- and region-specific codes (e.g., bone, joint, vessel, tendon), with no single assignable code covering the full scope.
363323002 (Surgical repair procedure by method)(not mapped)This is a SNOMED meta-classification concept that organises repair procedures by the method or technique used (e.g., grafting, suturing); ICHI does not have an equivalent organisational axis or code grouping procedures by repair method across all body sites.
363324008 (Surgical repair procedure by morphology)(not mapped)This is a SNOMED meta-classification concept grouping repair procedures by the morphological abnormality being corrected (e.g., fistula repair, aneurysm repair); ICHI has no equivalent meta-axis, as its classification is structured by anatomical target, action, and means rather than morphological category.
415682000 (Surgical time out)(not mapped)ICHI contains no code representing a surgical time-out, surgical safety checklist pause, or pre-incision verification step; extensive searching across perioperative, safety, checklist, verification, and health-service domains returned no meaningful match, as this administrative safety practice does not appear to be within ICHI's coded scope.
281179006 (Survey of dental model)(not mapped)ICHI contains no code for surveying or analysing a dental study model/cast, which is a prosthodontic/orthodontic planning procedure; this level of procedural granularity (examination of a physical plaster or digital dental model) is absent from ICHI's dental section (KAE codes), which covers clinical chair-side dental procedures only.
46534002 (Suspension and fixation)(not mapped)"Suspension and fixation" is a high-level SNOMED grouper concept spanning fixation and suspension procedures across all body parts; ICHI has no single generic code for this action class — only body-part-specific fixation/suspension codes (e.g., NMH.LC.AA for vaginal suspension and fixation), none of which captures the full breadth of this parent concept.
53677007 (Suture of laceration of nose)(not mapped)The ICHI nose block (JAA) contains no category-level code for repair or suture of the nose; available codes cover fistula closure (JAA.MK.AA) and reconstruction (JAA.ML.AA), neither of which represents simple laceration suture, so no reasonable mapping exists.
446184003 (Assessment using visual analog scale)(not mapped)The VAS is a generic measurement instrument applicable to many domains (pain, nausea, mood, fatigue, etc.), and ICHI has no concept representing a domain-agnostic scale-based assessment; no single ICHI code captures this without imposing a specific clinical domain that the SNOMED concept deliberately leaves unspecified.
445577007 (Assessment using visual infusion phlebitis scale)(not mapped)ICHI has no code for assessing phlebitis at a peripheral IV insertion site; the nearest candidate (ITB.AA.ZZ — Assessment of blood vessel functions) is too generic and relates to vessel function rather than a clinical observation of an IV site for phlebitis, making it an unreasonable mapping.
450730008 (Assessment using World Health Organization surgical safety checklist first edition)(not mapped)The WHO Surgical Safety Checklist is a perioperative quality-and-safety verification tool applied immediately before and during surgery; ICHI contains no codes for surgical safety verification, pre-operative checklists, or analogous perioperative safety assessment processes, and no reasonable approximation exists in the classification.
1351578005 (Assisted hatching)(not mapped)Assisted hatching is a specific IVF laboratory technique in which the zona pellucida of an embryo is mechanically, chemically, or laser-drilled to facilitate implantation; ICHI contains codes for oocyte retrieval, fertilisation, and embryo transfer but has no code representing this zona pellucida manipulation procedure.
67142005 (Assisting physician with procedure)(not mapped)ICHI classifies health interventions by what is done to or for a patient, not by the role or support activity of one clinician assisting another clinician. There is no ICHI concept representing this administrative/workforce coordination act.
122464004 (Augmentation procedure)(not mapped)"Augmentation procedure" is a high-level SNOMED grouper concept encompassing augmentation of many different body sites (skin, breast, bladder, labour, etc.). ICHI has specific augmentation codes for each body site (e.g., LCA.LK.AA for breast, NAI.LK.AA for bladder, SH for labour) but no single overarching "augmentation procedure" category that could serve as a parent; even the ICHI blocks do not consolidate these under a single augmentation hierarchy, making any single code assignment semantically misleading.
406800009 (Auramine stain method)(not mapped)Auramine staining is a fluorescent dye technique used in laboratory microscopy (primarily for TB detection), but ICHI does not model staining methods or laboratory techniques at this level of granularity. The essential laboratory test codes in the XG block focus on specific analyte-based tests rather than the technical staining method employed.
74468003 (Autogenous vaccine preparation)(not mapped)ICHI contains no code for preparing an autogenous (patient-specific, pathogen-derived) vaccine; the classification includes vaccination administration codes (DTB.VD.AC/AE) and a medicaments block (UAC), but none capture the laboratory process of preparing a custom autologous vaccine from a patient's own microorganisms.
43939005 (Autopsy service by diener)(not mapped)A diener (mortuary technician) provides preparatory and support services for the pathologist conducting the autopsy; this is an ancillary technical-assistance role with no corresponding ICHI category, and mapping it to the autopsy examination code would misrepresent the nature of the service.
59543001 (Autopsy, clerical procedure)(not mapped)This concept describes clerical/administrative work associated with an autopsy (e.g., paperwork, scheduling, documentation) rather than a clinical or technical health intervention; ICHI does not classify administrative clerical activities, and assigning PZA.AE.AA would incorrectly imply the autopsy examination itself was performed.
29915004 (Autopsy, clerical with coding procedure)(not mapped)This concept represents the administrative act of clerical processing and diagnostic coding of autopsy results — a health information management activity — which falls entirely outside ICHI's scope of clinical, rehabilitative, and public health interventions.
406801008 (Azo black stain method)(not mapped)ICHI contains no codes for specific named histological staining methods. The closest candidates (XG30Q5 Histopathology, XG69Q0 Microscopy) are far broader laboratory concepts that do not capture the notion of applying a specific dye technique to a specimen.
406802001 (Azocarmine G (GX) stain method)(not mapped)ICHI does not classify individual staining reagents or their application methods. No code within the Essential laboratory tests block or elsewhere covers a named dye-based staining technique such as Azocarmine G/GX.
406803006 (Azophloxin stain method)(not mapped)ICHI lacks any category representing specific cytochemical or histochemical staining procedures. Azophloxin is a counterstain used in Masson-type trichrome protocols, a level of specificity well below ICHI's granularity.
406804000 (Azorubin S stain method)(not mapped)No ICHI code exists for individual named staining methods. Azorubin S (also known as Carmoisine) is a specific histological dye technique that has no corresponding category in ICHI's classification structure.
406811001 (Azure A stain method)(not mapped)ICHI does not represent specific staining reagents or techniques such as Azure A (a thiazine dye used for nuclear and mucin staining). No code in the Essential laboratory tests block or the broader ICHI classification covers this level of procedural specificity.
228579003 (Backward chaining technique)(not mapped)Backward chaining is a specific behavioural/occupational therapy learning technique in which a task is taught in reverse sequence; ICHI contains no code for chaining techniques, operant conditioning methods, or analogous behavioural skill-acquisition approaches, and no sufficiently close alternative exists.
104247008 (Bacterial endotoxin measurement, tissue homogenization for culture)(not mapped)ICHI does not contain codes for endotoxin measurement (e.g., LAL assay) or tissue homogenization as a preparatory step for microbiological culture; these are highly specialised laboratory procedures that fall outside the scope of the ICHI Essential Laboratory Tests extension block.
51686005 (Banding)(not mapped)"Banding" as a standalone SNOMED concept is a generic, non-specific procedure term with no anatomical target, meaning no single ICHI code reasonably represents it. ICHI organises codes by specific target + action + means, so a context-free banding procedure cannot be mapped without further specificity.
385884006 (Bedrest care)(not mapped)ICHI does not contain a code representing prescribed bed rest as a therapeutic intervention or nursing care act. The closest structural candidate (PZA.LD.ZZ "Positioning of the whole body") refers to a physical repositioning procedure and does not capture the clinical concept of prescribing or managing bed rest as a treatment regimen.
405264000 (Bedside testing)(not mapped)ICHI does not have a code for the organisational concept of point-of-care or bedside testing as a modality. ICHI codes individual diagnostic tests by target and means (e.g., specific specimen collections or assays) but does not classify the location or delivery setting of testing as an independent intervention.
223433009 (Benefits education)(not mapped)"Benefits education" refers to educating patients or clients about social welfare entitlements and financial support, which is an administrative/social welfare domain not represented in ICHI. ICHI's education codes are tied to specific body functions or participation categories, and none map to social welfare benefit information provision.
228567003 (Benson technique)(not mapped)The Benson technique (relaxation response) is a specific mind-body relaxation and stress-reduction method; ICHI contains no codes for relaxation techniques, meditation, or the relaxation response, and fuzzy searching yielded no usable match across the classification.
121334009 (Beta blocker identification)(not mapped)Extensive searching across terms including "drug identification," "drug detection," "pharmaceutical," "substance analysis," "toxicology," and "blood test" returned no relevant ICHI codes for laboratory identification of a specific drug class. ICHI does not contain codes for pharmaceutical substance identification at this level of specificity.
10820006 (Beta lactamase measurement)(not mapped)Searches for "beta lactamase," "enzyme measurement," "antimicrobial resistance," "microbiological," "culture sensitivity," and "antibiotic" returned no relevant ICHI codes. ICHI does not represent specific microbiological enzyme assays such as beta-lactamase measurement at this level of granularity.
406815005 (Beta-glucuronidase stain method)(not mapped)Searches for "glucuronidase stain," "histochemical stain," "staining," "histology," "pathological examination," and "specimen" returned no relevant ICHI codes for this specific enzyme histochemical staining method. ICHI does not classify individual staining techniques at this level of specificity.
406816006 (Biebrich scarlet stain method)(not mapped)Biebrich scarlet is a histochemical laboratory staining technique applied to tissue sections on a bench, not a health intervention performed on a patient. ICHI does not classify laboratory staining methods, so no reasonable ICHI mapping exists.
104556004 (Bilirubin measurement, stool, qualitative)(not mapped)ICHI does not classify individual laboratory analyte measurements on stool specimens; the Essential Laboratory Tests extension block (XG1) covers a limited set of global-health-priority tests and does not include bilirubin stool testing. No suitable ICHI category or block exists for this concept.
236998006 (Bimanual uterine massage)(not mapped)ICHI contains no code for uterine massage or manual uterine stimulation; the uterus block (BlockL5-NME) includes tamponade, repositioning, and examination but not massage, and no generic massage code in ICHI is specific to the uterus.
58779000 (Bioassay)(not mapped)ICHI does not contain a generic bioassay code; the essential laboratory tests block (BlockL1-XG1) covers specific named assays (immunoassays, nucleic acid tests, etc.) but has no code representing bioassay as a general class of biological activity measurement.
56402004 (Biopsy of mucous membrane)(not mapped)Mucous membranes line multiple organ systems and ICHI encodes biopsy only at specific organ-level targets with no generic "mucous membrane" category. No single ICHI code adequately represents this anatomically non-specific SNOMED concept.
446500004 (Biopsy of ulcer)(not mapped)ICHI classifies biopsies by anatomical target structure, not by pathological lesion type; there is no concept of "biopsy of ulcer" (a site-independent pathological finding) anywhere in the classification. An ulcer biopsy would be coded to the specific anatomical site where the ulcer resides.
122547000 (Biopsy of upper aerodigestive tract)(not mapped)ICHI has no single code or block for "upper aerodigestive tract" as a combined anatomical concept; it classifies biopsies separately by site (nose, nasopharynx, oral pharynx, larynx, trachea, oesophagus, etc.). No individual site-specific code can represent the full scope of this SNOMED concept.
430278000 (Biopsy using fluoroscopic guidance)(not mapped)ICHI codes procedures by target anatomy and action, not by imaging modality alone; there is no cross-cutting code for fluoroscopy-guided biopsy as a procedure class. The extension code XG2RR6 (X-ray guided) exists as a post-coordination qualifier but cannot stand alone as a procedure code.
235413000 (Biopsy using mesh-covered balloon)(not mapped)ICHI has no code representing biopsy by instrument type (mesh-covered balloon); codes are organised by anatomical target, and no cross-cutting "balloon biopsy" category exists at any level in the classification.
91400004 (Bisection)(not mapped)"Bisection" is a generic surgical technique (cutting a structure into two parts) with no body-site specification, and ICHI organises all division/cutting procedures under specific anatomical targets. No single ICHI code represents body-site-unspecified bisection.
406817002 (Bismark brown R stain method)(not mapped)ICHI does not include histochemical staining methods as classifiable health interventions; the Bismark brown R stain is a laboratory technique used in tissue preparation and falls outside the ICHI classification scope.
406818007 (Bismark brown Y stain method)(not mapped)ICHI contains no classification for histochemical dye staining methods; these are laboratory tissue preparation techniques not represented anywhere in the ICHI hierarchy.
64040008 (Blood and body fluid laboratory precaution procedure)(not mapped)This SNOMED concept describes an infection-control precaution protocol specific to laboratory handling of blood and body fluids (e.g., universal precautions), which is an occupational safety/infection control procedure with no corresponding assignable ICHI code. The closest ICHI concepts (infection control measures, PZB.VE.ZZ isolation) do not match this laboratory precaution context.
250414003 (Blood concentration, test strip measurement)(not mapped)ICHI contains no code for point-of-care test strip measurement of blood analyte concentration; the Essential laboratory tests extension block (XG1) includes urinalysis test strips (XG4F04) but has no equivalent entry for blood test strip assays. No structural procedure code in the main ICHI classification covers this technique.
250208008 (Blood hematinic activity measurement)(not mapped)ICHI contains no code for measurement of hematinic (iron, B12, folate) activity in blood; neither the Essential laboratory tests block nor the main classification includes hematinic assays or related analyte activity measurements.
312349000 (Blood hematinic measurement)(not mapped)As with hematinic activity measurement, ICHI has no corresponding code for blood hematinic measurement; the classification does not cover iron studies, serum B12, or folate assays at the category level, making any match impossible.
406819004 (Blue shade eosin stain method)(not mapped)ICHI does not classify histological or cytological staining techniques as standalone health interventions; the closest available codes (XG30Q5 Histopathology, XG69Q0 Microscopy) are extension/ancillary codes that describe broad laboratory methods, not a specific dye staining protocol.
445232009 (Boost radiation therapy)(not mapped)ICHI encodes radiotherapy as a means (BA) applied to specific anatomical targets but has no concept representing a boost dose or boost-phase radiotherapy as a standalone procedure category independent of target organ.
152198000 (Brachytherapy)(not mapped)ICHI contains "Brachytherapy seeds" only as an extension/means code (not a standalone assignable intervention), and all radiotherapy codes in ICHI are organ-specific. There is no generic, site-independent brachytherapy procedure code.
69497001 (Brachytherapy isodose calculation, intermediate)(not mapped)ICHI does not contain any radiation dosimetry, treatment planning, or isodose calculation codes — these are physics/planning activities outside ICHI's scope of classifiable health interventions.
406820005 (Brazilin stain method)(not mapped)ICHI does not contain codes for histochemical staining methods or laboratory tissue-staining procedures such as brazilin (a natural dye used in bone/cartilage staining).
5246001 (Breakpoint cluster region analysis)(not mapped)BCR analysis is a molecular cytogenetic test for BCR-ABL1 fusion gene rearrangements; ICHI has no category for cytogenetic or molecular breakpoint analysis. The only related extension code (XG0DG2) is a quantifier, not an assignable intervention.
719415004 (Breathlessness care)(not mapped)ICHI does not contain a code for breathlessness (dyspnoea) care as a holistic intervention. The JTB block covers individual respiration function interventions, but none captures the multi-dimensional symptom management concept.
406821009 (Brilliant cresyl blue stain method)(not mapped)ICHI does not classify specific histological or haematological staining techniques; brilliant cresyl blue (used for reticulocytes) has no corresponding code, as ICHI lacks the granularity for individual staining reagent methods.
406822002 (Brilliant crocein stain method)(not mapped)ICHI does not represent specific histochemical staining reagent methods; brilliant crocein (used in connective tissue staining protocols such as van Gieson variants) has no corresponding ICHI code.
406823007 (Brilliant orange stain method)(not mapped)Brilliant orange staining is a histological/cytological specimen staining technique. ICHI does not classify laboratory staining methods or dye protocols.
406824001 (Brilliant yellow stain method)(not mapped)Brilliant yellow staining is a laboratory specimen staining technique outside ICHI's scope. Searches across staining, dye, histology, and cytology returned no applicable category.
133901003 (Burn care)(not mapped)"Burn care" is a broad, multi-component clinical concept (encompassing debridement, dressings, grafting, fluid resuscitation, rehabilitation, and pain management) with no single ICHI code capturing it as a package of care; assigning any single procedure code would misrepresent the concept, and no burn-specific grouping block exists in ICHI.
789282001 (Butyrylcholinesterase genotype determination)(not mapped)Butyrylcholinesterase genotype determination is a specialised pharmacogenomic molecular genetic test for anaesthesia risk, and ICHI's laboratory section contains no genetic testing codes beyond a narrow set of infectious disease nucleic acid tests; no code exists that reasonably covers this procedure.
789281008 (Butyrylcholinesterase phenotype determination)(not mapped)ICHI has no codes for enzyme phenotyping or pharmacogenetic testing; there is no specimen collection or laboratory assessment code that captures the specific act of determining butyrylcholinesterase phenotype, and no broader category fits without being entirely unrelated.
77281003 (Calcofluor white stain)(not mapped)Calcofluor white is a specific fluorescent microscopy staining technique used for fungal and parasitic detection in clinical microbiology. ICHI contains no staining, fluorescence microscopy, or fungal diagnostic codes; the essential laboratory tests block covers only a narrow set of WHO-prioritised tests without this procedure.
228729003 (Calculation of brachytherapy)(not mapped)This SNOMED concept refers to the dosimetric pre-treatment planning calculation for brachytherapy, which is a planning/administrative activity rather than a clinical intervention on a body part. ICHI does not include treatment planning or dosimetry calculation activities.
420807005 (Calculation of corneal tissue ablation depth)(not mapped)This concept represents a pre-operative computational planning step (calculating how much corneal tissue to ablate in laser refractive surgery), not a direct clinical intervention. ICHI's cornea block contains measurement, surgical, and transplant procedures but no refractive surgery planning or ablation calculation code.
228723002 (Calculation of external beam radiation therapy)(not mapped)Like the brachytherapy calculation concept, this refers to dosimetric treatment planning for external beam radiotherapy — a pre-treatment computational activity outside ICHI's scope. ICHI encodes radiotherapy as the means axis within destruction procedures for specific body sites, but contains no codes for the planning or dosimetry calculation phase of radiotherapy.
228730008 (Calculation of radionuclide therapy)(not mapped)ICHI contains no code for dosimetry planning or dose calculation for radionuclide/radioisotope therapy; all radiotherapy-related ICHI codes represent the clinical execution of treatment, not the pre-treatment mathematical calculation step.
64302003 (Calculus analysis)(not mapped)ICHI contains codes for extraction of calculi from various anatomical sites but has no code for the chemical or compositional analysis of calculi; this type of laboratory examination of removed stones falls outside ICHI's coded scope.
168031001 (Calculus examination)(not mapped)ICHI contains codes for calculus extraction from specific organs and dental examination, but no code exists for a general "calculus examination" as a diagnostic or assessment procedure; site-specific dental and oral examination codes do not capture the concept of examining a calculus generally.
413738001 (Cancer monitoring first letter)(not mapped)ICHI classifies health interventions as clinical or public-health actions and has no codes for administrative patient correspondence such as a monitoring recall letter; there is no plausible ICHI category that meaningfully represents this concept.
413740006 (Cancer monitoring second letter)(not mapped)As with the first monitoring letter, ICHI does not classify administrative correspondence or patient recall letters; no code in the classification represents this administrative follow-up activity, and assigning one would be semantically misleading.
121335005 (Carbohydrate identification)(not mapped)ICHI does not contain codes for biochemical laboratory analyte identification (such as carbohydrate testing); the Essential Laboratory Tests block is an extension/supplementary grouping and does not contain a carbohydrate or macronutrient identification category. No reasonably equivalent ICHI intervention code exists.
386228008 (Cardiac precautions)(not mapped)"Cardiac precautions" is a nursing/care coordination concept (activity restriction, safe mobilisation protocols post-cardiac event) that does not correspond to any assessable, therapeutic, or diagnostic intervention category in ICHI; no ICHI code captures safety precaution protocols as a health intervention type.
119759004 (Cardiovascular system closure)(not mapped)"Cardiovascular system closure" in SNOMED is a high-level grouper concept for surgical closure steps applied to cardiovascular structures; ICHI organises closure as site-specific codes (e.g., atrial septal closure, arterial duct closure) with no single code representing generic cardiovascular closure, and no assignable category or block corresponds to this abstract grouper concept.
119760009 (Cardiovascular system reconstruction)(not mapped)ICHI has specific reconstruction codes for individual cardiovascular structures (e.g., HZZ.ML.AA for heart, IZE.ML.AA for blood vessel NEC) but no single assignable code covering reconstruction of the cardiovascular system as a whole. The SNOMED concept is a high-level category that spans both cardiac and vascular reconstruction, and no ICHI category adequately represents this combined scope.
390820004 (Care for mentally disordered offenders)(not mapped)ICHI contains a range of mental health intervention codes (psychotherapy, counselling, assessment of mental functions) but none that capture the forensic or criminal-justice context that defines care for mentally disordered offenders. No code in ICHI addresses the intersection of psychiatric care and legal detention/offending, so no reasonable match exists.
705073009 (Care of conscious patient)(not mapped)This SNOMED concept denotes a broad administrative/contextual category describing routine clinical care provided to an awake, non-sedated patient; ICHI encodes specific health interventions rather than patient-state-defined care contexts, and no assignable ICHI code corresponds to this concept.
309637002 (Care of equipment by device)(not mapped)ICHI does not include codes for the maintenance or care of health equipment or devices — this is an operational/administrative act outside ICHI's scope of health interventions. No text, fuzzy, or hierarchical searches returned any relevant result.
309638007 (Care of equipment by procedure)(not mapped)As with its sibling concept, procedural care of equipment falls outside ICHI's scope, which classifies interventions on persons, populations, and the environment rather than on health technology or devices. No suitable ICHI code was found across all search strategies.
133893008 (Care of neurological patient)(not mapped)ICHI does not contain a concept representing general nursing or clinical care of a neurological patient as a package. The closest existing code, AZZ.AA.ZZ ("Neurological assessment, not elsewhere classified"), covers only assessment rather than the full care episode implied by the SNOMED concept, making it an insufficient match.
431245002 (Care of subject following anesthesia)(not mapped)Exhaustive searching (anesthesia, anaesthesia, post-anesthesia, perioperative, postoperative, recovery, patient care, monitoring) found no ICHI code representing post-anaesthesia recovery care or PACU-type management; the closest result PZA.DC.AF (intravenous anaesthesia) and DC (anaesthesia) are the administration of anaesthesia itself, not post-anaesthesia monitoring or care.
736161001 (Care planning education)(not mapped)ICHI does not contain a code for education specifically about care planning as a process; the PM (education) action axis codes are all targeted to specific body functions or conditions, and none addresses care planning methodology or care plan development as an educational topic. No reasonable ICHI match exists.
409057001 (Care regimes surveillance)(not mapped)ICHI has no concept corresponding to the monitoring or surveillance of care plans/treatment regimes as a clinical or administrative activity. The "surveillance" codes in ICHI (U-section) cover public health environmental surveillance only, and no monitoring codes address oversight of care regimes.
406825000 (Carminic acid stain method)(not mapped)ICHI does not classify laboratory histochemical staining techniques — specific dye or stain methods such as carminic acid are outside its scope. No staining, histochemistry, or specific dye-method codes exist in the classification.
406826004 (Carmoisine A stain method)(not mapped)As with other specific histological stain methods, ICHI does not cover individual dye-based staining techniques. Carmoisine A (acid red 14) staining has no corresponding code or even a broader staining category within ICHI.
3981005 (Carrier detection, molecular genetics)(not mapped)ICHI has no molecular genetics testing codes; the only genome-related intervention in ICHI is PYA.PP.ZZ (Genetic counselling), which is a counselling service rather than a laboratory diagnostic procedure. Carrier detection by molecular methods falls outside the ICHI scope entirely.
306684001 (Case closure by social services department)(not mapped)ICHI has no concept representing administrative case closure, and its social/community blocks (SX1, PZB) cover interventions for engaging in community life or care coordination rather than the administrative act of closing a case by a social services department. No reasonable ICHI match exists.
281621005 (Casting of dental study model)(not mapped)ICHI contains no code for fabricating a dental study model or dental impression/cast; the dental interventions block (KAE) covers clinical tooth procedures but not diagnostic or laboratory model-making activities of this kind.
385911009 (Cataract care management)(not mapped)ICHI contains no code for ongoing cataract care management as a distinct clinical management encounter; the closest eye-related management codes are limited to device/prosthetic management (e.g. BBE.SN.AA, BZZ.SM.AH), none of which captures a general cataract care management encounter. No reasonable match exists.
89693002 (Catheterization of hepatic vein)(not mapped)There is no specific ICHI code for catheterization of the hepatic vein; the abdominal/pelvic vein block (BlockL5-IED) contains no catheterization code for hepatic vein specifically, and IED.DL.AF is explicitly for the umbilical vein only. No other ICHI code reasonably represents selective hepatic vein catheterization.
30457000 (Catheterization of renal vein)(not mapped)There is no specific ICHI code for catheterization of the renal vein. The abdominal/pelvic vein block (BlockL5-IED) has no catheterization code applicable to the renal vein, and IED.DL.AF is specifically and exclusively for umbilical vein catheter insertion, making it inappropriate as a match.
2794006 (Cauterization of navel)(not mapped)The ICHI block for abdominal wall and umbilical interventions (BlockL5-PAO) contains only biopsy, local excision, and hernia repair codes — there is no destruction or cauterization code for the umbilicus/navel, and no suitable match exists elsewhere in ICHI.
406827008 (Celestine blue B stain method)(not mapped)ICHI does not represent specific histochemical staining techniques such as Celestine blue B; it contains only high-level codes like Histopathology (XG30Q5, an extension code) and Microscopy (XG69Q0), neither of which maps meaningfully to a named staining method.
250194009 (Cell phenotype determination)(not mapped)ICHI contains no code for general cell phenotype determination or immunophenotyping; the only remotely related codes (XG2GV7, XG5FX1) are specific essential laboratory extension codes for defined lymphocyte panels and leukaemia flow cytometry, neither of which represents the broad methodological concept of determining cell phenotype.
252335009 (Cell phenotyping)(not mapped)ICHI does not contain a code for cell phenotyping as a general laboratory method, and the available XG-series extension codes are too specific (defined leukaemia panels, named lymphocyte subsets) to serve as a reasonable mapping.
85457002 (Centrifugation)(not mapped)ICHI does not classify laboratory processing techniques such as centrifugation as standalone interventions; exhaustive searches for centrifugation, specimen processing, specimen preparation, separation, and related terms returned no relevant results.
80077002 (Centrifugation following chemical treatment)(not mapped)As a specific two-step laboratory processing technique (chemical treatment followed by centrifugation), this concept is even more granular than basic centrifugation and has no representation in ICHI; ICHI does not cover pre-analytical specimen preparation workflows at any level of granularity.
252399001 (Cerebrospinal fluid culture)(not mapped)ICHI does not contain codes for microbiological culture as a standalone diagnostic procedure; searches for "cerebrospinal fluid culture," "microbial culture," "bacterial," "microorganism," and "microbiology" all returned no relevant results, and the XA1N55 (Cerebrospinal fluid) entry is an extension/anatomy code, not a procedure.
167699000 (Cerebrospinal fluid examination)(not mapped)ICHI has no dedicated code for laboratory examination of cerebrospinal fluid as a procedure; the only ICHI CSF-related entity (XA1N55) is a specimen-descriptor extension code, not an assignable intervention code. No broader "body fluid examination" category exists in the classification.
1324000 (Cerebrospinal fluid IgG ratio and IgG index)(not mapped)ICHI contains no code for CSF immunoglobulin measurement or CSF IgG ratio/index calculation; XG58X6 "Immunoglobulin plasma levels" specifies plasma as matrix and does not cover CSF, and no calculated-index codes exist anywhere in the classification.
55347007 (Cerebrospinal fluid IgG synthesis rate)(not mapped)ICHI has no code for CSF IgG synthesis rate, which is a derived/calculated laboratory value specific to intrathecal immunoglobulin production; the closest candidate XG58X6 "Immunoglobulin plasma levels" is wrong in both specimen type (plasma) and method (direct measurement vs. calculated rate).
413016008 (Cerebrospinal fluid index)(not mapped)ICHI contains no code for a CSF index (typically a calculated composite value such as the CSF/serum albumin quotient or similar ratio); neither the laboratory tests block nor any other section includes derived-index or ratio procedures for body fluids.
313526009 (Cerebrospinal fluid lactate measurement)(not mapped)ICHI's only lactate code is XG37U7 "Whole blood lactate," which explicitly specifies blood as the specimen matrix and cannot be applied to CSF; no generic lactate measurement or CSF chemistry code exists elsewhere in the classification.
412983004 (Cerebrospinal fluid net bilirubin absorbance)(not mapped)ICHI contains a bilirubin extension code (XG9ZK8) and a CSF specimen entity (XA1N55) but no assignable intervention code for spectrophotometric bilirubin absorbance measurement of CSF; this highly specific analyte-level laboratory test has no corresponding ICHI category code.
412888007 (Cerebrospinal fluid organic acid measurement)(not mapped)ICHI does not contain any code for organic acid measurement in any body fluid, including CSF; this is a highly specific metabolic/biochemical laboratory test that falls below the granularity of the current ICHI classification.
412886006 (Cerebrospinal fluid potassium measurement)(not mapped)While ICHI covers electrolyte balance function assessment (ETE.AA.ZZ) at the physiological function level, there is no assignable ICHI code for measuring a specific electrolyte (potassium) in CSF; that level of analyte-specific laboratory chemistry granularity is absent from ICHI.
122438005 (Cervical mucus analysis)(not mapped)ICHI contains no code for cervical mucus analysis (a fertility assessment test); no sufficiently specific match exists under cervix uteri interventions, female genital system assessment, or laboratory specimen analysis categories.
232181007 (Change of mastoid pack)(not mapped)ICHI has no code for mastoid packing or its replacement; the mastoid sinus block only covers incision and mastoidectomy procedures, and packing-replacement codes exist only for nasal and external auditory canal sites, not the mastoid.
103754009 (Change of prescription of spectacles)(not mapped)ICHI contains no code for prescribing or revising optical/spectacle prescriptions; there is a device entry referencing spectacles for low vision but no assignable intervention code for issuing or changing a spectacle prescription.
32069008 (Chart abstracting by exception)(not mapped)Chart abstracting by exception is a health information management process (selectively extracting clinical data when normal parameters are exceeded) and has no corresponding ICHI category; ICHI does not include health information management or administrative data-extraction procedures.
107728002 (Chart evaluation by healthcare professional)(not mapped)Chart evaluation (review of a patient's clinical record by a healthcare professional) is a health information management activity with no dedicated ICHI category; ICHI does not classify documentation review or record-based clinical decision activities as standalone interventions.
57430006 (Chart evaluation by non-healthcare professional)(not mapped)ICHI has no concept representing evaluation or review of a medical chart/health record by any type of professional; the classification does not cover administrative record-review activities.
46526008 (Chart review, verification of procedures)(not mapped)ICHI contains no concept for reviewing or verifying documented procedures in a patient record; administrative quality-assurance activities over documentation fall outside ICHI's scope, which covers interventions performed on patients rather than reviews of records about those interventions.
225678000 (Checking hearing aid)(not mapped)ICHI does not have a dedicated code for checking or verifying hearing aid function; the closest structural analogue (cardiac device function check) applies only to cardiac implantable devices. The hearing-related codes in CTB focus on assessment/testing of hearing function, not verification of an assistive device's operation.
117053004 (Chemical separation method)(not mapped)ICHI does not include laboratory separation techniques (chromatography, electrophoresis, centrifugation, etc.) as standalone classifiable interventions; these are analytical methods that fall outside ICHI's clinical procedure scope. No ICHI category or block provides a reasonable mapping.
51671004 (Chemical test, qualitative)(not mapped)ICHI does not contain a generic category for qualitative chemical testing as an abstraction; the qualitative test codes in ICHI are all disease- or analyte-specific, and no general-purpose qualitative chemical test code exists in the classification.
229583009 (Chemically-activated ice pack treatment)(not mapped)ICHI contains no codes for cold therapy, cryotherapy packs, or thermotherapy physical modalities at this level of specificity; the hydrotherapy codes present (PMA.ZZ.BS, PNA.ZZ.BS, PZA.ZZ.BS) relate to immersion hydrotherapy and are semantically distinct from topical cold pack application.
128423004 (Chemocautery)(not mapped)Chemocautery (tissue destruction using caustic chemicals) has no dedicated ICHI code; ICHI's destruction codes are all body-site-specific (skin, brain, liver, etc.) with no generic or site-unspecified chemical cautery code, and the means axis in ICHI has no chemical cautery modality. Without knowing the target site, no single ICHI code can represent this concept.
1137696006 (Chemoprevention)(not mapped)ICHI contains a "Preventing" block but has no code representing chemoprevention (administration of pharmacological agents to prevent disease onset or progression). The medicament codes (UAC block) cover medication management and provision, not primary disease prevention through drug administration.
397973002 (Chemosurgery by Mohs' technique, first stage, including the removal of all gross tumor and delineation of margins)(not mapped)ICHI has no code representing Mohs micrographic surgery, which is a distinct staged excision technique with intraoperative margin-controlled histological analysis. The skin excision and destruction codes (e.g. LAA.JI.AA, LAA.GA.AH) do not capture the defining staged/margin-delineation methodology, and no ICHI code comes close enough to warrant even a relatedto assignment.
398016001 (Chemosurgery, first stage, including the removal of all gross tumor and delineation of margins)(not mapped)This is a site-unspecified description of first-stage Mohs micrographic surgery (chemosurgery with gross tumor removal and margin delineation). ICHI has no code or block representing this staged, margin-controlled excision technique regardless of body site, so no reasonable mapping exists.
719294004 (Chest drain care education)(not mapped)ICHI contains procedural codes for pleural drainage (JCB block) and general education codes about body functions, but has no education or care-management code targeting a specific medical device such as a chest drain. No ICHI code adequately captures patient education specifically about chest drain care.
35755007 (Chiropractic interpretation of x-rays)(not mapped)ICHI codes imaging procedures (taking the x-ray, e.g. MBA.BA.BA) but does not have a distinct action code for interpreting or reporting on pre-existing images; the act of reading radiographs as a standalone intellectual procedure falls outside ICHI's coding scope.
121336006 (Chlorinated hydrocarbon identification)(not mapped)ICHI does not contain codes for analytical toxicology or laboratory identification of specific chemical compound classes such as chlorinated hydrocarbons; searches across laboratory tests, chemical interventions, and identification procedures returned no usable match. This type of forensic/analytical chemistry procedure falls outside ICHI's scope.
122479006 (Chondrectomy)(not mapped)ICHI lacks a generic "excision of cartilage" code; cartilage interventions are represented only at specific anatomical sites (knee, shoulder, hip, ankle) and only as procurement, repair, or division — not as a general chondrectomy. The SNOMED concept is a broad, site-unspecified procedure class with no equivalent or even approximate counterpart in ICHI.
54826005 (Chromatography measurement)(not mapped)ICHI does not include analytical laboratory techniques such as chromatography as procedure codes; its essential laboratory tests block (BlockL1-XG1) contains specific named assays but nothing representing a chromatographic analytical method, and no broader "laboratory analysis" category exists to serve as even a relatedto match.
171242005 (Chromosome abnormality screening)(not mapped)ICHI contains no cytogenetic or chromosomal screening codes; the only genome-related code (PYA.PP.ZZ, Genetic counselling) represents a distinct intervention, and the screening-behaviour block (VDB) covers population health advocacy rather than the diagnostic test itself.
88960003 (Chromosome analysis)(not mapped)ICHI has no karyotyping or cytogenetic analysis code; the single genome intervention (PYA.PP.ZZ, Genetic counselling) and the extension code XG30Q5 (Histopathology) do not encompass chromosomal analysis, leaving no reasonable ICHI equivalent.
406830001 (Chromotrope 2R stain method)(not mapped)ICHI does not classify individual histological or histochemical staining techniques; no staining method codes exist in the classification, and the nearest extension code XG30Q5 (Histopathology) represents a broad category rather than a specific staining procedure.
406831002 (Chrysoidine R stain method)(not mapped)ICHI does not contain codes for specific histological staining methods or dyes; the classification has no representation of laboratory tissue preparation techniques such as chrysoidine staining. The closest ICHI extension codes (XG30Q5 Histopathology, XG69Q0 Microscopy) represent the overall examination category, not the preparatory staining method, and are too semantically distant for a reasonable mapping.
406832009 (Chrysoidine Y stain method)(not mapped)As with Chrysoidine R, ICHI has no codes for specific histological staining dyes or stain preparation methods; dye-specific laboratory techniques are below the granularity of the ICHI classification. No ICHI code comes close enough to constitute even a relatedto mapping.
87751001 (Cineradiography)(not mapped)Cineradiography is dynamic fluoroscopic X-ray imaging recorded as a motion sequence and is not limited to any specific body part or function; ICHI has no generic cineradiography or fluoroscopy code — the only fluoroscopy code in ICHI (KTC.BA.BB, Video fluoroscopy to evaluate swallowing) is too narrow and site-specific to serve as a mapping for the general technique.
29861003 (Circulating inhibitor assay, factor II)(not mapped)ICHI has no code for coagulation factor-specific inhibitor assays; the XG1 essential laboratory tests block covers only high-level coagulation tests (e.g., prothrombin time, partial thromboplastin time) and does not include factor-specific inhibitor measurement at any level of the hierarchy.
24643008 (Circulating inhibitor assay, factor IX)(not mapped)ICHI has no code for coagulation factor-specific inhibitor assays; the XG1 essential laboratory tests block covers only high-level coagulation tests and does not extend to factor-specific inhibitor assays for factor IX or any individual coagulation factor.
71517003 (Circulating inhibitor assay, factor VIII)(not mapped)ICHI has no code for coagulation factor-specific inhibitor assays; despite factor VIII inhibitor assay being clinically important (e.g., in acquired haemophilia A), no ICHI code exists at this level of granularity — the closest available tests are XG5E59 (partial thromboplastin time) and XG8J48 (prothrombin time/INR), which are far broader screening tests.
386239006 (Circulatory precautions)(not mapped)"Circulatory precautions" is a nursing intervention concept involving protective measures for compromised circulation (e.g., limb positioning, avoiding constriction, temperature management); ICHI has no precautions or protective-care category in its circulatory system chapter, and the only residual code IZZ.ZZ.ZZ ("Interventions on the circulatory system, unspecified") is a catch-all residual that does not meaningfully represent this nursing care concept.
225330006 (Client participation)(not mapped)"Client participation" is an organisational or care-process concept describing patient involvement in care, not a discrete health intervention. No ICHI code captures this as an assignable procedure.
185922005 (Clinical drug trial)(not mapped)ICHI does not contain a code for clinical research or drug trials as an intervention category; the classification focuses on health interventions delivered to individuals, not research study designs or experimental treatment protocols.
75332002 (Clostridium difficile toxin assay)(not mapped)ICHI contains no code for C. difficile toxin testing; the Essential Laboratory Tests (XG block) covers only a limited panel of priority tests with no entry for C. difficile or enteric toxin assays.
21147007 (Closure by clip)(not mapped)ICHI encodes wound closure as part of body-part-specific repair codes where the means axis specifies approach/instrument; no standalone technique-only code for "clip closure" exists.
50015006 (Closure by staple)(not mapped)ICHI does not have a technique-only wound closure code; no surgical stapling method code exists independently of the target body part.
18557009 (Closure by suture)(not mapped)ICHI encodes suturing only within body-part-specific repair codes and has no anatomy-independent "closure by suture" concept; this SNOMED concept represents a generic technique modifier rather than a complete intervention.
66525004 (Closure by tape)(not mapped)No ICHI code exists for tape-based wound closure as a standalone intervention; ICHI's wound/skin management codes are always anchored to a body-part target.
14133008 (Closure by wire)(not mapped)ICHI has no concept representing wire as a general closure technique — it is a means/instrument, not a procedure category with its own code. No ICHI category captures the concept of closure using wire across body sites.
281837002 (Closure of amputation stump)(not mapped)ICHI encodes amputations but has no category for secondary closure or revision of an amputation stump; the concept of stump closure as a distinct subsequent procedure is absent from the classification.
449662003 (Closure of lower limb)(not mapped)ICHI contains no code for closure of a lower limb wound or surgical site; the lower limb blocks cover vascular, musculoskeletal, and rehabilitation interventions but not generic wound/surgical closure of the limb.
16638003 (Closure of postauricular fistula of mastoid)(not mapped)ICHI's mastoid block (CDA) contains only incision, mastoidectomy, and obliteration codes; there is no code for repair or closure of a mastoid fistula, and no adjacent ear/mastoid block contains a fistula closure concept.
34665004 (Closure with prosthetic implant)(not mapped)ICHI does not have a body-part-agnostic "closure with prosthetic implant" code — all closure codes are tied to specific anatomical targets, making this generic SNOMED qualifier concept unmappable at any single ICHI category.
117264008 (Cold incubation of serum, 1 week)(not mapped)Describes a specific laboratory pre-analytical/analytical technique (cold incubation of serum for one week, used in cryoglobulin or cold agglutinin detection). ICHI does not include pre-analytical sample processing or incubation steps; its essential laboratory tests block covers named tests at the assay level only.
117266005 (Cold incubation of serum, 2 days)(not mapped)Cold incubation of serum is a highly specific pre-analytical laboratory technique defined by its temperature condition and duration. ICHI contains no code for this procedure or any closely related serum incubation technique; the nearest haematological testing codes are far too broad and do not capture the pre-analytical incubation nature.
117265009 (Cold incubation of serum, 24 hours)(not mapped)This duration-specific cold serum incubation procedure has no counterpart in ICHI. It is a pre-analytical step defined by both temperature and a specific time interval, a level of granularity not represented anywhere in the ICHI classification.
117267001 (Cold incubation of serum, 3 days)(not mapped)Same cold incubation of serum procedure differentiated only by a 3-day incubation duration. No ICHI code exists for cold serum incubation at any duration; the classification does not represent this pre-analytical laboratory technique.
117268006 (Cold incubation of serum, 4 days)(not mapped)The 4-day cold serum incubation variant is equally absent from ICHI. All duration variants of this SNOMED concept represent the same unrepresented procedure type in ICHI.
117336001 (Cold incubation of serum, 4 hours)(not mapped)The 4-hour cold incubation of serum has no ICHI match. Searching across laboratory test codes, haematological assessment codes, and immunological function codes yielded no code that meaningfully represents cold serum incubation at any temperature or duration.
117334003 (Cold incubation of serum, 5 days)(not mapped)ICHI does not contain codes for in-vitro laboratory procedures such as cold agglutinin incubation. The ICHI essential laboratory tests block covers only a narrow panel of population-level tests and has no representation of cold incubation protocols or serological incubation techniques.
117335002 (Cold incubation of serum, 6 days)(not mapped)ICHI does not represent in-vitro cold incubation procedures regardless of duration. No relevant code, block, or residual category exists in the ICHI hierarchy for this laboratory technique.
764929005 (Collection of exhaled breath specimen)(not mapped)ICHI contains no specimen collection code for exhaled breath or condensate; the respiratory section covers functional assessment, measurement, and training of respiration but not exhaled-breath specimen collection as a distinct intervention.
44733008 (Collection of string test)(not mapped)The Entero-Test/string test (swallowed gelatin capsule with nylon string for duodenal/proximal jejunal sampling) has no counterpart in ICHI; there is no duodenal specimen collection code, and the PZX NEC block codes are too generic to convey the highly specific and distinctive technique involved.
118022004 (Colony count)(not mapped)Colony count is a quantitative microbiology laboratory technique (counting bacterial colonies on culture media) — a downstream analytical step, not a health intervention in the ICHI sense. No ICHI code exists for this concept; the essential laboratory tests block does not include microbiological colony enumeration.
306840004 (Combination therapy to back)(not mapped)ICHI contains no concept of "combination therapy" as a multimodal physical/electrotherapy approach, and rehabilitation codes target body functions rather than anatomical regions such as the back. No ICHI code meaningfully captures the combined-modality, site-specific nature of this intervention.
306839001 (Combination therapy to hand)(not mapped)As with combination therapy to other body regions, ICHI lacks both a "combination therapy" concept and site-specific rehabilitation codes for the hand; functional training codes (e.g., muscle or movement function training) capture only individual modality components and omit the defining multimodal character of the intervention.
306833000 (Combination therapy to neck)(not mapped)ICHI has no equivalent for combined physical/electrotherapy directed at the neck; the closest structural block (BlockL4-MAA, musculoskeletal structures of head or neck) contains only surgical procedure codes, and functional rehabilitation codes do not map to anatomical treatment sites such as the neck.
306834006 (Combination therapy to trunk)(not mapped)ICHI does not have a concept of "combination therapy" as a multi-modal treatment category; it encodes individual interventions (e.g., phototherapy, radiotherapy, pharmacotherapy) separately rather than as combined regimens. No ICHI code captures this aggregate concept targeting the trunk, and even browsing the integumentary system block (BlockL5-LAB) reveals no combined-modality category.
703423002 (Combined chemotherapy and radiation therapy)(not mapped)ICHI has no "chemotherapy" axis value or combined chemoradiation concept; radiotherapy in ICHI is coded only as a destructive means applied to specific anatomical targets (e.g., LAB.GA.BA), and there is no cross-body-system combined-modality treatment code to represent concurrent systemic chemotherapy plus radiation.
185531002 (Combined opportunistic and cohort screening)(not mapped)ICHI's screening-related codes fall under the health behaviours chapter (BlockL4-VDB "Interventions on screening behaviours"), which addresses population-level behaviour modification rather than the clinical delivery method of a screening programme, so neither opportunistic nor cohort screening delivery strategies are represented as distinct ICHI concepts.
1303933004 (Combined superficial venous arterialization and selective venous occlusion of lower limb)(not mapped)This highly specific surgical technique — arterialising the superficial venous system while selectively occluding selected veins to create directional flow in the lower limb — has no equivalent in ICHI; the closest individual components (IFD.LI.AA bypass of vein of lower limb, IFD.LA.AA occlusion of lower limb vein, IFA.ML.AA reconstruction of artery of lower limb) each capture only a partial aspect and none represent the combined procedure concept.
732219004 (Combined treatment method)(not mapped)"Combined treatment method" is a high-level methodological/approach concept in SNOMED CT (indicating that more than one treatment modality is used together) rather than a specific clinical intervention, and ICHI does not have a corresponding meta-level code for combined or multimodal treatment approaches.
385897008 (Comfort care management)(not mapped)ICHI contains no concept for palliative, comfort, or end-of-life care management as a distinct intervention category. No suitable code or block represents this concept, even at a broader level.
185438005 (Communication from:)(not mapped)"Communication from:" is a SNOMED administrative/documentation concept representing an incoming correspondence record (e.g., a letter from a GP or specialist), not a health intervention. ICHI classifies therapeutic or public health interventions and has no equivalent for administrative inbox or document-receipt concepts.
45379005 (Complete avulsion)(not mapped)"Complete avulsion" is a descriptor of injury severity/morphology, not a health intervention or procedure. No ICHI code exists for it, as ICHI classifies what clinicians do (interventions), not the nature of injuries sustained.
79095000 (Complete excision)(not mapped)"Complete excision" in SNOMED is a generic, body-site-agnostic grouper concept with no direct structural equivalent in ICHI, where all excision codes require a specific target body part. No ICHI code representing a body-site-independent total excision exists.
20874001 (Complete excision of anus)(not mapped)The KBX block (Interventions on anus and anal canal) contains partial excision (KBX.JJ) and local excision of lesion (KBX.JI) codes but no total/complete excision of the anus code — that action code (JK) does not exist for the KBX target. No sufficiently close ICHI code was found.
178841003 (Complex reconstruction operations on hand and foot)(not mapped)ICHI has no code that spans both hand and foot in a single reconstruction procedure, and no general "complex reconstruction" category exists for either structure. The available hand and foot blocks (BlockL4-MGB for hand) only contain tissue-specific reconstruction codes (bone, ligament, muscle, tendon) rather than a combined or overarching complex reconstruction code, leaving this SNOMED concept without a suitable ICHI match.
49651002 (Complex surgical repair of eyelids, nose, ears and lips)(not mapped)This SNOMED concept describes a combined multi-site facial surgical repair spanning four distinct anatomical targets (eyelids, nose, ears, lips); ICHI has individual reconstruction codes for each structure (BAA.ML.AA, JAA.ML.AA, CAC.ML.AA, KAA.ML.AA) but no single code representing their combined repair. No ICHI code covers this multi-structure composite procedure.
313100009 (Component of vascular procedure)(not mapped)This is a SNOMED CT grouper/qualifier concept representing a component or sub-step of a vascular procedure rather than a standalone health intervention; ICHI classifies complete interventions, not procedural sub-components, so no ICHI code corresponds to this abstract grouper concept.
717340001 (Cone beam CT guided aspiration)(not mapped)ICHI contains CT-guided imaging as an extension code (XG2209) but no base intervention code combining aspiration with cone beam CT guidance across unspecified body sites; the aspiration codes that exist are body-site-specific (orbit, gallbladder, bladder, prostate, testes) and none applies to the generic concept of cone beam CT guided aspiration. A valid ICHI code would require a target body site, which this generic SNOMED concept does not specify, so no reasonable single ICHI assignment can be made.
725465000 (Cone beam CT guided cryoablation of lesion)(not mapped)ICHI has no code for cryoablation as a technique, and all percutaneous destruction-of-lesion codes are body-site-specific (e.g., liver, lung). This SNOMED concept specifies no body site, so no single ICHI category code can be assigned; the imaging guidance modality (cone beam CT) is also not represented in ICHI.
717687001 (Cone beam CT guided insertion of drain)(not mapped)ICHI models drainage as body-site-specific percutaneous drainage codes (e.g., pleural cavity, peritoneal cavity) and has no generic or NEC "insertion of drain" category that is independent of anatomical target. Because this SNOMED concept names no body site, no ICHI code can be applied without introducing clinically incorrect specificity.
725836001 (Cone beam CT guided laser ablation)(not mapped)ICHI does not distinguish ablation technique (laser, cryo, RF) within its destruction-of-lesion codes, and all relevant codes are tied to a specific body site. This SNOMED concept specifies no anatomical target, making it impossible to assign any ICHI category code without fabricating a site specification.
441783000 (Conformal radiotherapy)(not mapped)ICHI encodes radiotherapy only as body-site-specific destruction codes (e.g., "Destruction of lesion or tissue of prostate by radiotherapy") and has no technique-level code for conformal radiotherapy as a modality independent of anatomical target. The only body-site-neutral radiotherapy code, PZA.GA.BA (Total body irradiation), refers to a clinically distinct procedure and is not an appropriate match.
117055006 (Congo red stain method)(not mapped)ICHI does not classify laboratory staining methods as distinct interventions; the Essential Laboratory Tests extension block covers only essential diagnostics (blood tests, serology, PAP smear, post-mortem, etc.) with no histochemical staining codes. Congo red staining is a specific laboratory technique used to detect amyloid and has no corresponding ICHI category or extension code.
314271007 (Conscious sedation)(not mapped)ICHI has no code for sedation, conscious sedation, or procedural anaesthesia — these are not represented in the ICHI classification as stand-alone health interventions, and no related code was found through text search, fuzzy matching, or hierarchy browsing.
225309002 (Constant supervision)(not mapped)ICHI has no concept representing continuous or constant supervision as a health intervention; searches for "supervision", "monitoring", "observation", and "surveillance" yield only organ-specific physiological monitoring or public health surveillance codes, none of which captures the nursing/care activity of maintaining constant watch over a person.
18641003 (Construction of pouch)(not mapped)"Construction of pouch" refers to creating an intestinal reservoir (e.g., ileal J-pouch or colonic J-pouch), but ICHI has no specific pouch construction code — neither the colon block (KBP) nor the small intestine block (KBK) contains a reservoir or pouch creation category — and no sufficiently close code exists to support even an approximate mapping.
698312002 (Consultation for minor abdominal procedure)(not mapped)ICHI does not have codes for pre-procedural consultations or encounter-type activities, and there is no abdominal consultation or procedure-planning code that could reasonably represent this administrative/clinical encounter concept without misrepresenting its meaning.
77965002 (Consultation in brachytherapy)(not mapped)ICHI does not have a concept for a pre-treatment consultation or clinical advisory encounter in the context of brachytherapy; the only brachytherapy-related entry in ICHI is "Brachytherapy seeds" (an extension/means code, not an assignable intervention category). The SNOMED concept specifically describes a consultation activity which falls outside the scope of any available ICHI category.
1144767008 (Consultation in external beam radiation therapy)(not mapped)ICHI contains no category for a pre- or peri-treatment consultation encounter specific to external beam radiation therapy; radiotherapy-related ICHI codes describe the destructive intervention itself, not the associated clinical consultation.
65981005 (Consultation in laboratory medicine for test interpretation)(not mapped)ICHI has no code representing a clinical consultation focused on interpreting laboratory results; searching on "test interpretation," "laboratory," "consultation," and "specialist" all returned no relevant assignable category. The concept is a specialty advisory encounter and lies outside the procedural scope covered by current ICHI categories.
711031001 (Contracting for adherence)(not mapped)"Contracting for adherence" is a specific behaviour-change technique in which a formal written agreement is negotiated between clinician and patient to reinforce treatment compliance; ICHI has no code for therapeutic contracting, and the counselling and psychotherapy codes do not capture the defining element of a behavioural contract.
257954006 (Conversion from prosthetic arthroplasty)(not mapped)ICHI has no concept representing "conversion from" a prosthetic arthroplasty as a general procedure independent of body site; site-specific codes capture only the replacement of a joint device at a single site and presuppose a different clinical scenario.
239704005 (Conversion of static cast brace to functional cast brace)(not mapped)ICHI encodes "replacement of external immobilisation device" only at named anatomical sites (skull, maxilla, spine, etc.); there is no body-site-neutral code for replacing one cast brace type with another, and the SNOMED concept is site-unspecified. The concept therefore cannot be mapped to a single ICHI category without imposing an incorrect anatomical specificity.
278507002 (Corn and callus procedures)(not mapped)ICHI contains no code for removal or treatment of corns and calluses (hyperkeratotic skin lesions); the closest candidates such as debridement or local excision of skin of the lower limb are anatomically non-specific and the SNOMED concept is itself a category grouper covering a range of podiatric interventions.
1231302001 (Correction of congenital anomaly of lower limb)(not mapped)No ICHI assignable category code exists for correction of congenital anomaly of the lower limb as a general procedure; the relevant musculoskeletal lower limb NEC block contains only rehabilitation codes, and no broader surgical correction code is available.
1231301008 (Correction of congenital anomaly of upper limb)(not mapped)No ICHI assignable category code exists for correction of congenital anomaly of the upper limb as a general procedure; the musculoskeletal upper limb NEC block contains only rehabilitation codes, and no broader surgical correction code is available.
239624000 (Correction of congenital deformity)(not mapped)This SNOMED concept is a high-level category covering correction of any congenital deformity across all body systems; ICHI has no single cross-body-system code for this, and no candidate code is specific enough to serve as a meaningful mapping without being grossly misleading.
711137004 (Count of instruments and sponges during surgery)(not mapped)ICHI does not contain a code for intraoperative instrument and sponge counting, which is a surgical safety/quality procedure rather than a health intervention on a patient target, action, or behaviour. No code in the health services, safety, or perioperative domains covers this specific procedural safety check.
71661000 (Cover slip preparation)(not mapped)Cover slip preparation is a laboratory technique for mounting microscopic specimens onto glass slides — a pre-analytical step that falls outside ICHI's scope of health interventions. Fuzzy/synonym searches (microscopy preparation, slide preparation, specimen preparation, tissue preparation) returned nothing relevant.
180127002 (Creation of tibiofibular synostosis)(not mapped)Surgical bony fusion of tibia and fibula has no dedicated ICHI category; the closest ICHI content under MNB (Interventions on bone of lower leg) covers osteotomy, bone grafts, and epiphysiodesis but not synostosis creation, and arthrodesis codes apply only to joints.
405331002 (Creation of upper limb arteriovenous fistula)(not mapped)ICHI's upper limb artery block contains bypass, reconstruction, occlusion, and endarterectomy codes but has no code for arteriovenous fistula creation; the NEC artery block similarly has only IZA.SN.AF "Management of arteriovenous shunt" (maintenance, not creation).
121337002 (Cresol identification)(not mapped)Cresol is a specific phenolic chemical compound, and its laboratory identification is an analytical chemistry/toxicology procedure with no corresponding code in ICHI; ICHI does not cover this level of granular laboratory substance-identification testing.
252944002 (Crossover test)(not mapped)SNOMED 252944002 refers to a haematological crossmatch/compatibility test, and ICHI contains no equivalent code for crossmatch, crossover, or blood compatibility testing.
55303001 (Crushing of contents of intestine)(not mapped)ICHI contains no code for mechanical manipulation or fragmentation of intestinal luminal contents; the intestinal procedure blocks cover biopsy, excision, destruction, drainage, and repositioning, but not crushing of intraluminal content.
65511005 (Crushing of vas deferens)(not mapped)The ICHI vas deferens / spermatic cord block (NGD) contains codes for ligation, excision, and other procedures, but has no code for crushing or compression; no reasonable ICHI equivalent exists.
427357007 (Cryosurgery)(not mapped)ICHI is a target-action-means classification and does not have a generic "cryosurgery" code as a standalone procedure type; cryo technique is represented only as a means/extension modifier applied to specific body site destruction codes.
312280008 (Crystal identification)(not mapped)Crystal identification (typically polarised light microscopy of synovial fluid for urate or calcium pyrophosphate) is a laboratory diagnostic technique with no corresponding ICHI procedure code.
48191009 (Crystal identification, chemical)(not mapped)Chemical crystal identification is a specialised laboratory technique not represented anywhere in ICHI; neither the essential laboratory tests extension codes nor the main intervention hierarchy contain a code for chemical crystal analysis.
413809006 (CSF 5-Hydroxyindole acetic acid level)(not mapped)Measurement of 5-HIAA in cerebrospinal fluid is a highly specific neurochemical laboratory assay that is not represented in ICHI.
1251639001 (CT discogram with injection of contrast into intervertebral disc)(not mapped)ICHI contains no discography code and no code for diagnostic contrast injection into an intervertebral disc; the intervertebral disc block only contains destruction, excision, reduction, and repair codes.
76718005 (CT guided aspiration of cyst)(not mapped)ICHI organises interventions by anatomical target structure, not by pathological content (cyst); there is no generic "aspiration of cyst" code that spans body sites, and no body site is specified in this SNOMED concept.
277591006 (CT guided biopsy)(not mapped)ICHI requires a specific anatomical target as the first axis; there is no generic "biopsy of unspecified site" category code.
702497003 (CT guided drainage)(not mapped)ICHI organises drainage codes by anatomical target site and approach and has no generic site-unspecified drainage procedure code; the SNOMED concept is intentionally site-agnostic.
433918001 (CT guided ethanol ablation)(not mapped)ICHI's percutaneous destruction codes are all tied to specific anatomical targets and none represents a generic site-unspecified percutaneous chemical/ethanol ablation.
431864000 (CT guided injection)(not mapped)ICHI has no generic "CT-guided injection" code applicable across all body targets; CT guidance is represented only as an extension code appended to specific procedure codes.
866263002 (CT guided insertion of drainage tube)(not mapped)ICHI has no generic "drainage tube insertion" code — all drainage codes are body-site specific; the SNOMED concept is body-site unspecified.
430434007 (CT guided insertion of stent)(not mapped)ICHI stent codes are all site-specific (cardiovascular, colonic, biliary, ureteric, etc.) and none represent a generic body-site-unspecified CT-guided stent insertion.
277584008 (CT guided percutaneous therapeutic drainage)(not mapped)Site-agnostic SNOMED grouper for CT-guided percutaneous drainage; ICHI organises drainage codes by specific anatomical target with no cross-cutting unspecified-site or image-guided drainage category.
710791003 (CT guided puncture and aspiration)(not mapped)Site-agnostic SNOMED grouper for CT-guided puncture and aspiration; ICHI requires a specific anatomical target for aspiration/puncture codes with no general unspecified-site grouper.
278009009 (CT guided removal of foreign body)(not mapped)ICHI foreign body removal codes are body-site-specific; no generic site-unspecified "removal of foreign body" code exists, and the SNOMED concept specifies no body site.
429855002 (CT guided skin marking)(not mapped)ICHI has no code for procedural skin marking/tattooing as a standalone image-guided intervention; no marking, localization, tattooing, or dye injection category exists.
1343563002 (CT of choana)(not mapped)ICHI has no CT code for the choana (posterior nasal aperture) or the nasopharynx; the nasopharynx imaging block contains only plain X-ray and conventional contrast radiogram codes.
710794006 (CT of feeding tube)(not mapped)ICHI has no CT or imaging code targeting a feeding tube, NG tube, or PEG tube as the subject of imaging; the gastrostomy block covers only assessment, management, closure, and education.
241559008 (CT ovary)(not mapped)ICHI contains no CT imaging code for the ovary; the NMA block has no imaging sub-codes and no female genital organ CT code exists in the classification.
441427002 (Culture of embryo with coculture of oocytes)(not mapped)ICHI has no code covering in-vitro embryo culture or coculture with oocytes as an assisted reproduction technique; the laboratory ART procedure has no reasonable ICHI match.
406836007 (Curcumin stain method)(not mapped)ICHI does not contain histochemical or special staining methods; there are no codes for staining techniques (curcumin or otherwise) in the ICHI classification.
68688001 (Curettage)(not mapped)ICHI does not have a generic "curettage" procedure code — the only curettage codes are site-specific uterine procedures, and no reasonable mapping exists for the non-site-specific concept.
120643004 (Cyanide ascorbate screen)(not mapped)The cyanide-nitroprusside test is a qualitative urine screen for cystinuria; ICHI contains no code for this specific biochemical screening test.
44489000 (Cystic fibrosis carrier detection)(not mapped)ICHI contains no codes for genetic carrier testing, CFTR mutation analysis, or disease-specific molecular screening.
73735000 (Cytogenetic procedure)(not mapped)No ICHI code exists for cytogenetic procedures; searches for cytogenetic, chromosome, karyotype and genomic returned no results.
14361005 (Cytopathology clerical procedure including coding)(not mapped)ICHI does not classify administrative or clerical activities such as coding of cytopathology results.
117298004 (Cytopathology staining method)(not mapped)ICHI classifies interventions, not laboratory techniques such as staining methods; no reasonable match exists.
25621005 (Daily full psychiatric care of inpatient)(not mapped)ICHI does not classify care delivery modes or bundled inpatient psychiatric care episodes.
737850002 (Day care case management)(not mapped)ICHI does not classify administrative care management activities.
184275008 (Death notification from hospital)(not mapped)Death notification is an administrative/legal documentation activity outside ICHI's scope.
312774004 (Debridement of amputation stump)(not mapped)ICHI has no code for debridement of an amputation stump as a distinct anatomical target.
438577005 (Decalcification procedure)(not mapped)Generic site-agnostic concept; ICHI has no decalcification codes at any anatomical site.
307558008 (Decompression of intestine)(not mapped)ICHI has no code for intestinal decompression (relief of distension or obstruction).
171959006 (Decompression of pituitary gland)(not mapped)The pituitary gland block contains no decompression/release code.
433470006 (Dehydration of tissue specimen)(not mapped)Tissue dehydration is a histological processing step performed in the laboratory after specimen collection; ICHI contains no codes for specimen preparation or processing of this kind.
73344001 (Delaying of pedicle graft)(not mapped)ICHI has no code for the surgical delay procedure of a pedicle flap or graft; XG9JE8 is only an extension qualifier ("pedicle flap"), not a procedure code.
30969004 (Denervation of carotid body)(not mapped)The carotid body (a chemoreceptor paraganglion at the carotid bifurcation) has no dedicated surgical procedure codes in ICHI; the classification covers interventions on the carotid artery but not on the carotid body as a discrete target.
115597007 (Description of specimen character)(not mapped)ICHI does not contain codes for gross/macroscopic description of specimen characteristics; this is a pathology workflow activity (narrating or recording the appearance of a specimen) that falls outside ICHI's scope of classifiable health interventions.
363065001 (Destruction of lesion by modality)(not mapped)This SNOMED concept is a high-level abstract category describing destruction of any lesion by any modality, with no anatomical or technique specificity; ICHI is structured around specific target-action-means combinations and has no single code that encompasses destruction of a lesion across all body sites and modalities.
15395004 (Destruction of lesion of cul-de-sac)(not mapped)ICHI has no code for the rectouterine cul-de-sac (pouch of Douglas) as a target; no peritoneal pouch or rectouterine destruction code exists in ICHI.
54755008 (Destruction of lesion of eye)(not mapped)ICHI organises eye destruction codes by specific anatomical structure with no single unspecified-eye destruction code equivalent to the generic SNOMED concept; the eye NEC group lacks a destruction category.
178060006 (Destruction of lesion of fascia)(not mapped)ICHI contains no destruction (GA) codes for fascia at any body site; fascia interventions are limited to incision, release, excision, repair, and reconstruction.
230908007 (Destruction of lesion of intracranial vessel)(not mapped)The intracranial artery and vein blocks contain no destruction (GA) action codes; no analogous destructive lesion code exists for intracranial vessels in ICHI.
1303470002 (Destruction of lesion of perineum)(not mapped)The ICHI perineum block (PAW) contains no destruction code — closest available codes are local excision and debridement, neither of which captures destruction.
59411003 (Destruction of tissue of diaphragm)(not mapped)The ICHI diaphragm block (MCX) contains only biopsy, imaging, device insertion, and repair codes — there is no destruction action code for the diaphragm in the classification, and no sufficiently close alternative exists in adjacent blocks.
373355003 (Destructive procedure of eye proper)(not mapped)ICHI has destruction codes only for specific sub-structures of the eyeball (conjunctiva, cornea, iris, ciliary body, anterior chamber, retina, sclera, vitreous, chorioretinal) but no single code representing destruction of the eye as a whole.
45835000 (Destructive procedure of pelvic region)(not mapped)ICHI has no single code representing a destructive procedure on the pelvic region as a whole; only organ-specific pelvic destruction codes exist (bladder, uterus, prostate, peritoneum), none of which captures this broad SNOMED category concept.
69085006 (Destructive procedure on carotid body)(not mapped)The carotid body (glomus caroticum) does not appear as an interventional target in ICHI — it exists only as an extension code qualifier (XA0F61) with no corresponding procedure block or destruction category.
46792002 (Destructive procedure on extraocular muscle)(not mapped)The BDA block (Interventions on extraocular muscle) contains 12 children covering biopsy, incision, release, transposition, advancement, shortening, and repair, but no destruction or ablation code exists for extraocular muscle in ICHI.
444282008 (Detection of Tay Sachs disease carrier status)(not mapped)ICHI contains no code for Tay-Sachs disease carrier testing (enzymatic hexosaminidase A assay or molecular genetics), nor for lysosomal storage disorder screening or carrier status determination more generally; fuzzy and synonym searches (genetic, enzyme, carrier, newborn screening) all returned no relevant results.
443342006 (Determination of alpha-1-antitrypsin genotype)(not mapped)No ICHI code exists for alpha-1-antitrypsin genotyping or any equivalent genetic/molecular test for this specific protein; the ICHI Essential laboratory tests block does not include genotyping procedures of this type.
250261000 (Determination of amount of hemolysis)(not mapped)ICHI contains no code specific to measuring or quantifying hemolysis; related codes such as XG06E8 (Peripheral blood film examination) or XG2XJ6 (Complete blood count automated) address broader haematological assessment rather than hemolysis quantification specifically.
444309000 (Determination of karyotype from blood specimen)(not mapped)ICHI has no code for karyotype analysis or cytogenetic testing; the classification does not include chromosomal/genomic laboratory procedures beyond a limited essential lab test set, and no suitable match exists even at a broader level within the haematological or laboratory domains.
24214008 (Determinative histochemistry for chemicals)(not mapped)ICHI contains no code for histochemistry as a procedure; the closest entry is the extension code XG1640 "Immunohisto-chemistry", which is a different technique (antibody-based) and belongs to the extension code chapter rather than a proper intervention category. No ICHI category captures chemical-specific histochemical staining as a standalone procedure.
86171007 (Determinative histochemistry for enzymes)(not mapped)As with chemical histochemistry, ICHI has no category for enzyme-specific histochemical analysis; the extension code XG1640 "Immunohisto-chemistry" is the only remotely related entry but is a structurally different technique and not an assignable procedure category for this context.
185756006 (Diabetes monitoring first letter)(not mapped)This SNOMED concept represents an administrative/correspondence act — sending a first written recall letter to a patient for diabetes monitoring — and ICHI contains no code for written correspondence, patient recall letters, or sequential administrative contacts. No ICHI category meaningfully covers this concept.
705072004 (Diabetes monitoring invitation by short message service text messaging)(not mapped)This concept describes a specific administrative act of inviting a patient via SMS for diabetes monitoring follow-up; ICHI has no code for SMS-based or digital channel patient invitations or recall, and no broader category captures this administrative communication modality.
185757002 (Diabetes monitoring second letter)(not mapped)Like concept 185756006, this represents a sequential administrative recall letter (second in series) for diabetes monitoring follow-up, which falls entirely outside the scope of ICHI's coded interventions; no suitable category exists for written patient correspondence or ordered recall sequences.
252505001 (Diagnostic local anesthesia infiltration)(not mapped)ICHI does not have a dedicated assignable category for local anaesthesia infiltration used diagnostically (e.g., to confirm pain source). The only anaesthesia-related ICHI categories are general/inhalational/intravenous anaesthesia or site-specific joint injections; the concept of using local anaesthetic infiltration as a diagnostic test has no equivalent in ICHI.
406837003 (Diamond black stain method)(not mapped)Diamond black (also called Sudan black B) staining is a specific histochemical laboratory staining technique; ICHI contains no codes for specific histochemical or cytochemical staining methods, and no extension codes or categories cover named staining protocols at this level of granularity.
108184008 (Diaphragm excision)(not mapped)The ICHI block for diaphragm interventions (BlockL5-MCX) contains only biopsy, imaging, device insertion, and repair codes — no excision or resection of the diaphragm is present. Diaphragmectomy is a rare, highly specialized procedure for which ICHI has no assignable category.
711369001 (Diaphragm stripping)(not mapped)"Diaphragm stripping" refers to surgical stripping of tumour or metastatic deposits from the surface of the thoracic diaphragm (cytoreductive surgery), a distinct procedure from repair. ICHI has no excision, stripping, or debridement code under the MCX diaphragm block, and no broader trunk debridement code semantically covers this specific surgical act.
120168003 (Diaphragm transposition)(not mapped)ICHI contains transposition codes only for specific structures (cranial/peripheral nerve, extraocular muscles, parotid gland, salivary duct) and has no transposition or repositioning code for the diaphragm within BlockL5-MCX or elsewhere. No sufficiently related ICHI category exists for this rare reconstructive procedure.
17814008 (Differential solubility measurement)(not mapped)Differential solubility measurement is a specific laboratory biochemistry technique (used, for example, in haemoglobin S solubility testing) that has no corresponding code in ICHI; the ICHI essential laboratory tests block does not contain solubility-based assays at this level of specificity.
252224002 (Differential sugar absorption test)(not mapped)ICHI has no code representing a differential sugar absorption (lactulose/mannitol intestinal permeability) test; searches across absorption, intestinal permeability, function tests, breath tests, and provocation tests all failed to yield a relevant GI mucosal permeability assay. The closest candidates (PZA.AC.AC Food provocation test, PZA.AC.ZZ Provocation test NEC) are conceptually distinct — they challenge a food response, not measure differential urinary sugar excretion.
391277002 (Digestive system disease screening)(not mapped)ICHI's screening-related codes (VDB block) cover interventions on screening behaviours as a public-health behaviour target (e.g. advocacy, education, policy), not clinical disease screening procedures applied to the digestive system; no ICHI code represents a digestive system disease screening examination or programme at an appropriate level of specificity.
787996005 (Digitalizing tissue section)(not mapped)This histology/pathology workflow procedure (converting microscope slides to digital images via a whole-slide scanner) has no corresponding ICHI code; ICHI does not cover digital imaging of pathology specimens as an assignable intervention category.
363084003 (Dilation of lower respiratory tract)(not mapped)ICHI codes dilatation at the level of specific structures (trachea: JBA.LG.AD, bronchus: JBB.LG.AD) but has no single code or block-level assignable code representing dilatation of the lower respiratory tract as a whole. The SNOMED concept is a category-level grouper with no single ICHI equivalent that spans both trachea and bronchus together.
418244003 (Dilation of nasolacrimal duct)(not mapped)The BAD (lacrimal apparatus) block contains no dedicated dilatation code; the closest procedural codes are incision (BAD.FA.AA) and irrigation (BAD.JA.AA), neither of which captures dilation/probing of the nasolacrimal duct. With no acceptable approximation available, this concept is best marked unmatched.
47418008 (Dilation of nasolacrimal duct with insertion of tube or stent)(not mapped)The lacrimal apparatus block (BAD) contains no assignable dilation, stent-insertion, or device-insertion code for the nasolacrimal duct — only irrigation, drainage, and excision codes are present, and the "Nasolacrimal stent" entry in the classification has no assigned code. No other ICHI category captures this procedure.
235512008 (Direct measurement of pancreatic parenchymal pressure)(not mapped)ICHI contains pressure measurement codes for vascular structures and KCM.AB.AD for sphincter of Oddi pressure, but has no code for direct measurement of pressure within the pancreatic parenchymal tissue itself. The closest candidate (KCO.AE.AA, exploration of pancreas) does not capture pressure measurement semantics.
127796002 (Direct tissue immunofluorescence procedure)(not mapped)No ICHI code exists for direct tissue immunofluorescence — a specialized laboratory/pathology technique used on tissue biopsies (e.g., for autoimmune skin or renal disease). ICHI does not classify individual diagnostic laboratory analytic methods at this level of specificity, and no related candidate code was found through text, fuzzy, or hierarchy-based searches.
228571000 (Disassociation technique)(not mapped)"Disassociation technique" is a specific psychotherapeutic or NLP-derived technique used in trauma/pain management; ICHI contains no equivalent entry for dissociation or disassociation as a therapeutic technique, and fuzzy search returned only distantly related results with low similarity scores.
306493008 (Discharge by agency nurse)(not mapped)ICHI contains no code for the administrative act of discharging a patient from care, and no role-specific discharge codes exist. XG38D0 "Discharge planning" is an extension/qualifier code about planning for discharge, not the act of discharge itself, and does not capture the "by agency nurse" role distinction.
306391006 (Discharge by anesthetist)(not mapped)ICHI has no code representing patient discharge as an administrative act, nor any role-differentiated discharge codes. XG38D0 "Discharge planning" is a procedural modifier/extension code for planning, not for the act of discharge performed by an anesthetist.
306528009 (Discharge by arts therapist)(not mapped)ICHI does not encode patient discharge as a standalone administrative intervention, and makes no distinction by clinician role for discharge acts. No code in the classification corresponds to an arts therapist discharging a patient from care.
306858005 (Discharge by audiological physician)(not mapped)ICHI has no administrative discharge codes and no role-specific variants thereof. The only discharge-related ICHI entry, XG38D0 "Discharge planning," is a procedural nature qualifier, not a representation of the discharge act performed by an audiological physician.
306534002 (Discharge by audiologist)(not mapped)ICHI does not classify patient discharge as a health intervention, by any professional role. XG38D0 "Discharge planning" covers pre-discharge care coordination activity, not the act of discharge itself, and does not match this concept.
306535001 (Discharge by audiology technician)(not mapped)ICHI contains no assignable code for the act of patient discharge; the only related term "Discharge planning" (XG38D0) is an extension/descriptor code, not a standalone intervention, and does not capture the administrative discharge act or the performer role (audiology technician).
306385009 (Discharge by bereavement counselor)(not mapped)ICHI has no code representing patient discharge from care as a primary intervention; the performer role (bereavement counselor) is not encoded in ICHI, and no ICHI category or block reasonably covers this administrative discharge concept.
306418003 (Discharge by cardiologist)(not mapped)Patient discharge by a named clinician role is an administrative act with no corresponding assignable ICHI category; ICHI does not encode who performs a discharge, and "Discharge planning" (XG38D0) is an extension modifier code that addresses pre-discharge planning rather than the discharge act itself.
306436003 (Discharge by care of the elderly physician)(not mapped)ICHI lacks any assignable intervention code for administrative patient discharge; the specialty-specific performer dimension (care of the elderly physician) is outside ICHI's scope entirely, leaving no reasonable mapping candidate.
306419006 (Discharge by chest physician)(not mapped)As with the other discharge-by-role concepts, ICHI contains no assignable code for the act of discharging a patient from care, and the named performer role (chest physician) is not represented in the ICHI axis structure.
306417008 (Discharge by clinical allergist)(not mapped)ICHI contains no code representing the act of patient discharge, nor any role-differentiated discharge concept. The only discharge-related code, XG38D0 "Discharge planning," is an extension/modifier code describing planning activity and does not capture the administrative discharge act performed by a specific clinical role.
306422008 (Discharge by clinical hematologist)(not mapped)As with the other role-differentiated discharge concepts, ICHI has no code for patient discharge as a clinical act, and no mechanism within assignable codes to specify the discharging clinician's specialty. XG38D0 "Discharge planning" is an extension modifier only and does not represent discharge execution.
306423003 (Discharge by clinical immunologist)(not mapped)ICHI does not classify the administrative act of discharging a patient from care, regardless of specialty. No assignable ICHI category code exists for this concept, and the specialty of the discharging clinician (immunologist) is not representable in any available ICHI axis.
306424009 (Discharge by clinical neurophysiologist)(not mapped)ICHI does not include a code for the act of patient discharge from care, and neurophysiology-specific discharge is entirely outside ICHI's scope of assignable intervention categories. No acceptable approximation exists.
306494002 (Discharge by clinical nurse specialist)(not mapped)ICHI does not capture role-specific patient discharge, and no code exists for discharge by any nursing or specialist nursing role. The ICHI system does not encode who performs an administrative discharge act as a standalone classifiable intervention.
306392004 (Discharge by clinical oncologist)(not mapped)ICHI contains no code representing the act of discharging a patient from care. The only remotely related code, XG38D0 "Discharge planning," is an extension code for planning a future discharge — not the discharge act itself — and does not capture the clinical-oncologist role qualifier central to this concept.
306425005 (Discharge by clinical pharmacologist)(not mapped)ICHI has no code for patient discharge as a clinical act, either generically or qualified by practitioner role. The concept of a clinical pharmacologist releasing a patient from their care episode falls entirely outside ICHI's coded scope.
306426006 (Discharge by clinical physiologist)(not mapped)As with the other "Discharge by ..." concepts, ICHI does not represent the administrative act of formally ending a patient's episode of care. No ICHI category or block covers discharge by a clinical physiologist or any equivalent concept.
306512004 (Discharge by community nurse)(not mapped)ICHI contains no code for patient discharge from community nursing or any community-care episode. Searching "discharge," "end of care," and browsing administrative/health-service blocks yielded no applicable category.
306523000 (Discharge by community-based midwife)(not mapped)There is no ICHI code for midwifery discharge or any practitioner-role-specific discharge act. ICHI's maternity-related codes cover clinical procedures, not the administrative closure of a midwifery care episode.
306511006 (Discharge by community-based nurse)(not mapped)ICHI contains no code for the administrative/clinical act of discharging a patient from care by a named professional. The only discharge-related code, XG38D0 "Discharge planning", is an extension code describing the contextual nature of an intervention, not the discharge act itself, making it semantically unsuitable.
306427002 (Discharge by dermatologist)(not mapped)ICHI contains no code for the act of discharging a patient from care by a named professional. XG38D0 "Discharge planning" is a contextual extension code rather than a representation of the discharge act, and the professional role (dermatologist) is not encodable in ICHI codes.
306540009 (Discharge by dietitian)(not mapped)ICHI contains no code for the act of patient discharge by a named professional role. No discharge act, care termination, or case closure codes exist in ICHI beyond the extension code XG38D0 "Discharge planning", which captures planning activity rather than the act of discharging.
306428007 (Discharge by endocrinologist)(not mapped)ICHI contains no code representing the act of a named professional formally discharging a patient from their care. The administrative/managerial dimension of professional discharge is outside ICHI's coded intervention scope.
306394003 (Discharge by family planning doctor)(not mapped)ICHI contains no code for discharge from care by a named professional, and does not encode professional role as part of any intervention code. No reasonable ICHI category or block covers the concept of patient discharge as a distinct act.
306429004 (Discharge by gastroenterologist)(not mapped)ICHI does not contain a code representing the administrative act of patient discharge, nor does it encode the specialty of the discharging clinician. The only discharge-related entry, XG38D0 (Discharge planning), is an extension code describing the nature of an intervention rather than an assignable procedure code for the act of discharge itself.
306430009 (Discharge by general physician)(not mapped)ICHI does not contain a code representing the administrative act of patient discharge, nor does it encode the specialty of the discharging clinician. The only discharge-related entry, XG38D0 (Discharge planning), is an extension code describing the nature of an intervention rather than an assignable procedure code for the act of discharge itself.
306386005 (Discharge by genetic counselor)(not mapped)ICHI does not contain a code representing the administrative act of patient discharge, nor does it encode the specialty or role of the discharging clinician. The only discharge-related entry, XG38D0 (Discharge planning), is an extension code describing the nature of an intervention rather than an assignable procedure code for the act of discharge itself.
306431008 (Discharge by geneticist)(not mapped)ICHI does not contain a code representing the administrative act of patient discharge, nor does it encode the specialty of the discharging clinician. The only discharge-related entry, XG38D0 (Discharge planning), is an extension code describing the nature of an intervention rather than an assignable procedure code for the act of discharge itself.
306435004 (Discharge by genitourinary medicine physician)(not mapped)ICHI does not contain a code representing the administrative act of patient discharge, nor does it encode the specialty of the discharging clinician. The only discharge-related entry, XG38D0 (Discharge planning), is an extension code describing the nature of an intervention rather than an assignable procedure code for the act of discharge itself.
306438002 (Discharge by medical ophthalmologist)(not mapped)ICHI has no code representing the administrative act of a clinician discharging a patient from care; the only discharge-related entry (XG38D0 "Discharge planning") is an extension modifier, not a standalone procedure code, and describes discharge planning rather than the discharge decision itself.
306388006 (Discharge by mental health counselor)(not mapped)ICHI contains no code for the administrative act of discharging a patient from care by a named clinician type; the closest candidate XG38D0 ("Discharge planning") is an extension modifier rather than an assignable procedure code, and the counselor specialty is not a dimension encoded in ICHI.
306439005 (Discharge by nephrologist)(not mapped)ICHI does not represent clinician-specialty-based discharge acts as procedure codes; XG38D0 ("Discharge planning") is only an extension modifier and refers to discharge planning rather than the act of discharge, making no satisfactory match available for this administrative SNOMED concept.
306440007 (Discharge by neurologist)(not mapped)There is no ICHI category code for a specialist-performed patient discharge; the discharge-related extension code XG38D0 is not an assignable standalone procedure, and the neurologist specialty role is not captured in ICHI's target/action/means axes.
306441006 (Discharge by nuclear medicine physician)(not mapped)ICHI has no procedure code representing the act of discharging a patient by any named physician specialty; the only structurally related term (XG38D0 "Discharge planning") is an extension modifier describing the nature of an intervention, not an assignable procedure code for a discharge act.
306408008 (Discharge by pathologist)(not mapped)ICHI contains no code for the administrative act of patient discharge by a named professional type; "XG38D0 Discharge planning" is an extension descriptor for the planning activity surrounding discharge, not the discharge act itself, and does not capture professional-role specificity.
306445002 (Discharge by pediatrician)(not mapped)ICHI has no code representing the administrative act of discharge authorised by a particular clinical specialty; the concept describes a care pathway/administrative event that falls outside ICHI's scope of classifiable health interventions.
306551009 (Discharge by physiotherapist)(not mapped)ICHI does not represent professional-role-attributed discharge events; searches across discharge, physiotherapy, physical therapy, and rehabilitation terms yielded no applicable code for this administrative act.
306533008 (Discharge by play therapist)(not mapped)Neither "play therapy" nor any variant returned a relevant ICHI code, and ICHI has no mechanism for coding administrative discharge acts attributed to a specific professional role.
306536000 (Discharge by podiatrist)(not mapped)ICHI codes for podiatry exist only for surgical/structural interventions on foot and toe structures; the administrative act of discharge by a podiatrist has no ICHI equivalent.
306444003 (Discharge by rheumatologist)(not mapped)ICHI has no code representing the administrative act of discharging a patient from care by a specific clinical specialty. The only discharge-related ICHI term, XG38D0 (Discharge planning), is an extension code describing the planning nature of an intervention rather than a primary procedure code for this administrative event.
306557008 (Discharge by speech and language therapist)(not mapped)ICHI does not represent specialty-specific patient discharge acts as primary procedure codes. XG38D0 (Discharge planning) is an extension modifier, not a standalone procedure, and the speech and language therapy blocks (JU1, JUC, JUF) contain no concept for formal discharge from a therapy service.
306462007 (Discharge by surgeon)(not mapped)ICHI does not have a primary intervention code for the act of discharging a patient from surgical care; the only discharge-related ICHI term is the extension code XG38D0 (Discharge planning), which describes a care planning activity rather than the administrative discharge event by a surgeon.
306420000 (Discharge by thoracic physician)(not mapped)No ICHI code exists for the administrative act of patient discharge from the care of a thoracic physician or any specialty-specific discharge. ICHI models clinical interventions and their targets, not the administrative decision event of discharge from a named specialty service.
306563004 (Discharge from Accident and Emergency service)(not mapped)ICHI contains no code for discharge from an Accident and Emergency service; searches for "emergency," "discharge," and navigation of the health services block (UEP) confirm there is no primary ICHI category representing this administrative event from a specific care setting.
306568008 (Discharge from intensive care service)(not mapped)ICHI has no code for discharge from intensive care or any specialty-specific service discharge; even the only discharge-related code (XG38D0 "Discharge planning") is too broad and does not capture the ICU-specific nature of this concept.
306571000 (Discharge from medical service)(not mapped)ICHI does not represent the administrative event of discharge from a named clinical service; no code exists for discharge from a general medical service or equivalent specialty-level administrative act.
306604003 (Discharge from obstetrics and gynecology service)(not mapped)ICHI has no code for discharge from a specialty service; the obstetrics and gynecology dimension is entirely absent from any discharge-related concept in ICHI, making any mapping unreasonable.
306619002 (Discharge from occupational health service)(not mapped)ICHI has no code for service-level discharge events; while occupational health interventions exist in ICHI under the activities and environment chapters, there is no concept covering the administrative act of ending a patient's episode under an occupational health service.
306682002 (Discharge from ward)(not mapped)ICHI contains no code representing the administrative act of discharging a patient from a hospital ward. The only discharge-related ICHI code (XG38D0) covers the planning process, not the discharge event itself, and no ward/unit-level disposition concept exists in ICHI.
306809006 (Discharge from young disabled service)(not mapped)ICHI has no concept for discharge from a specialist disability service or from any specific care setting. The concept is an administrative disposition event with no counterpart in the ICHI classification, and no related codes capture service-specific discharge for disabled populations.
306689006 (Discharge to home)(not mapped)ICHI contains no code representing discharge to home as a disposition event. While PZB.TC.ZZ (Navigating the service system) touches on service transitions, it does not represent the specific administrative act of releasing a patient to their home setting, making any mapping too imprecise to be meaningful.
306705005 (Discharge to police custody)(not mapped)ICHI does not contain any code representing transfer or discharge to a non-health custodial setting such as police custody, as this falls outside the scope of health interventions that ICHI classifies. No approximate match exists anywhere in the classification.
410426007 (Discipline surveillance)(not mapped)"Discipline surveillance" refers to oversight/regulatory monitoring of professional conduct, a concept that falls entirely outside ICHI's scope — ICHI covers health interventions, not professional regulatory or governance actions. No ICHI code for public health surveillance or any other section matches this concept.
1251646005 (Discography with injection of contrast into intervertebral disc of cervical spine)(not mapped)ICHI contains no code for discography (contrast injection into an intervertebral disc for diagnostic imaging); the cervical intervertebral disc block has only biopsy, excision, implantation, reduction, and device removal codes, and no imaging sub-codes exist at the disc level.
1251647001 (Discography with injection of contrast into intervertebral disc of lumbar spine)(not mapped)ICHI has no code for lumbar discography; the lumbar intervertebral disc block contains no imaging codes, and the nearest available lumbar imaging code (lumbosacral myelogram) targets the spinal canal, not the disc itself.
1251648006 (Discography with injection of contrast into intervertebral disc of thoracic spine)(not mapped)The thoracic intervertebral disc block contains no imaging codes, and the thoracic myelogram is a spinal canal procedure that does not represent contrast injection into the disc itself.
738065000 (Discussion about solid organ transplantation)(not mapped)ICHI contains codes for performing transplantation procedures but has no code for advising about, discussing, or counselling regarding solid organ transplantation as a topic; the closest candidates (UEP.PN.ZZ advising about health services, PZB.PP.ZZ counselling NEC) are too generic to constitute a meaningful match.
716101005 (Discussion about telehealth monitoring)(not mapped)ICHI has a Telehealth extension block (BlockL1-XG6) covering how interventions are delivered remotely, but contains no code for a discussion or advisory encounter specifically about telehealth monitoring as a subject; VD1.PN.ZZ (advising about health service-related behaviours) is too broad and non-specific to qualify as even an inexact match.
1230264007 (Disinfection of infectious excretion)(not mapped)ICHI has no concept of disinfecting body excretions; the closest ICHI concepts are environmental decontamination codes targeting outdoor/indoor air, water, or soil — none match the clinical act of treating infectious excretion material.
1236973000 (Disinfection of skin of perineum)(not mapped)ICHI classifies interventions on the perineum (biopsy, drainage, debridement, repair, excision) but contains no code for skin disinfection or antiseptic preparation of any anatomical site; hygiene/infection control codes operate at population/environmental levels.
866037002 (Dispatch of specimen for second opinion)(not mapped)ICHI has no code representing the logistics of sending a specimen to another provider/laboratory for a second opinion. The action axis "AH" covers collecting specimens, and UEP.TI.ZZ covers referral, but neither captures dispatching an already-collected specimen.
448792007 (Dispensing of spectacles)(not mapped)ICHI has no assignable code representing the dispensing or supply of spectacles/eyeglasses; the only spectacles-related entry is an extension/supplementary product descriptor rather than an intervention code.
304700003 (Distraction training)(not mapped)ICHI contains no code for distraction training as a specific cognitive-behavioural technique; the structurally closest candidates (AUA.PH.ZZ — Training of attention functions; AXA.PP.ZZ — Counselling for pain) are either too generic or semantically distinct.
185469009 (District nurse visit)(not mapped)ICHI has no concept for a nursing home/community visit as a healthcare encounter type; the closest environmental block (UCK — Support from health professionals) addresses systemic support structures rather than individual clinical visit episodes.
363096005 (Division of eye structure)(not mapped)"Division of eye structure" is a high-level SNOMED grouper covering any division procedure on any ocular structure. ICHI has specific incision/division codes for individual eye structures but no single code representing division of an unspecified eye structure.
363098006 (Division of genital system structure)(not mapped)This is a SNOMED grouper concept for any division of any genital structure. ICHI has specific division codes for individual genital structures but no single code representing division of an unspecified or generic genital system structure.
62302004 (DNA analysis)(not mapped)ICHI's laboratory extension section covers specific named tests but contains no code for generic DNA analysis or genomic/molecular testing; no broader ICHI category representing DNA analysis was found.
384716004 (DNA hybridization)(not mapped)Searches for hybridization, nucleic acid testing, molecular, and genomic techniques returned no ICHI code representing the DNA hybridization technique; ICHI's laboratory codes are limited to specific named diagnostic tests.
84888000 (DNA hybridization assay)(not mapped)ICHI contains nucleic acid amplification tests but no code covers DNA hybridization as a technique — hybridization (Southern blot, FISH, ISH) is methodologically distinct from amplification and is not represented in the ICHI classification.
223493006 (Documenting observations)(not mapped)ICHI's "observation" codes represent the clinical act of observing a body function, not the administrative/informatics act of documenting or recording observations; no ICHI code covers health record documentation as a distinct intervention type.
268538000 (Donor status education)(not mapped)"Donor status education" concerns informing individuals about organ donor registration; no ICHI code covers this — ICHI education codes are anchored to specific body functions or systems with no organ-donation-awareness category.
1187287002 (Doppler ultrasonography of pelvis)(not mapped)ICHI has no generic "Ultrasound of pelvis" or "Ultrasound of pelvic region" code; pelvic imaging in ICHI is only available at the level of specific organs or structures, none of which captures the broad pelvic region implied by the SNOMED concept.
708247009 (Dot blot assay)(not mapped)ICHI does not contain any code for dot blot assay or equivalent membrane-based protein/nucleic acid detection techniques; the laboratory tests block has no entry for this analytical method.
81762006 (Double valve replacement)(not mapped)ICHI codes valve replacements individually per valve and has no combined or multi-valve replacement code; a combined aortic and mitral valve replacement procedure has no single representable ICHI category.
1156941002 (Double-blind clinical trial)(not mapped)ICHI classifies health interventions performed on patients rather than study designs or research methodologies; double-blind clinical trial is a research design concept with no corresponding intervention code.
122462000 (Drainage procedure)(not mapped)ICHI organises drainage by specific anatomical target (peritoneal cavity, pleural cavity, soft tissue, etc.); there is no single pan-anatomical "drainage procedure" assignable category, and the SNOMED concept spans dozens of distinct ICHI codes across multiple body systems.
702768002 (Drainage procedure using ultrasound guidance)(not mapped)ICHI expresses ultrasound guidance as an extension code (XG8MR0) appended to a site-specific drainage code, not as a standalone assignable category; combined with site-unspecified scope, no single ICHI category captures the full meaning.
385943009 (Drainage tube care assessment)(not mapped)ICHI assessment codes (action AA) apply to body functions and systems, not external device or tube care activities; no ICHI code exists for assessment of a drainage tube.
385945002 (Drainage tube care education)(not mapped)ICHI patient education codes (action PM) target body functions and health behaviours rather than device-specific care skills; no ICHI code exists for educating a patient or carer about drainage tube care.
385946001 (Drainage tube care management)(not mapped)ICHI device management codes (action SN) are site-specific (e.g., KMA.SN.AH peritoneal cavity); no site-agnostic drainage tube management category exists, and the SNOMED concept covers tube care in general without specifying anatomy.
117256002 (Drug screen test method, cut off >25 ng/ml)(not mapped)ICHI has no code representing a drug screening test, let alone one defined by a specific immunoassay cut-off threshold; the Essential Laboratory Tests block covers a curated WHO list with no toxicology entries.
117257006 (Drug screen test method, cut off >50 ng/ml)(not mapped)ICHI contains no drug screening or toxicology test codes, and the SNOMED concept additionally specifies a cut-off concentration that has no structural equivalent in ICHI.
3971006 (Duchenne muscular dystrophy carrier detection)(not mapped)ICHI has only one code under "Interventions on genome" (PYA.PP.ZZ — Genetic counselling), and no code exists for genetic carrier testing, molecular diagnosis, or dystrophin gene analysis.
406838008 (Durazol red stain method)(not mapped)Durazol red is a specific histochemical laboratory staining technique used on tissue specimens; ICHI does not classify individual staining or laboratory analytical methods.
385736008 (Dying care)(not mapped)"Dying care" (end-of-life/terminal/palliative care) has no category or block in ICHI for palliative, hospice, end-of-life, or terminal care.
386262008 (Dysreflexia management)(not mapped)Autonomic dysreflexia management is a multi-component nursing/clinical intervention targeting the autonomic response in spinal cord injury patients; no ICHI code captures this overall management activity.
359900000 (Ea rosette test)(not mapped)The E-rosette test (sheep red blood cell rosette formation for T-lymphocyte detection) is a granular historical immunological assay; ICHI does not classify individual lymphocyte-rosette receptor-binding assays at this level.
359906006 (Eac rosette test)(not mapped)The EAC-rosette test (erythrocyte-antibody-complement rosette formation for B-lymphocyte/complement receptor detection) has no ICHI counterpart; ICHI does not capture this granularity of historical immunological assay.
391269001 (Early intervention in psychosis HRGs)(not mapped)"Early intervention in psychosis HRGs" is a UK Healthcare Resource Group administrative classification representing a service delivery bundle, not a specific health intervention; no ICHI code covers this type of administrative grouping.
1256107005 (Ecotherapy)(not mapped)ICHI contains no code for ecotherapy or its synonyms (nature-based therapy, horticultural therapy, wilderness therapy, green therapy); the closest creative therapy entries are distinct modalities that do not subsume ecotherapy.
385932001 (Edema control)(not mapped)ICHI has no code for edema control as a general intervention category; the only oedema-related result has a broken/missing code in the dataset and represents only one specific technique rather than the broad SNOMED concept.
385931008 (Edema control assessment)(not mapped)No ICHI code exists for assessing or evaluating edema control; searches across assessment, oedema, fluid balance, and vascular function returned no applicable match.
385934000 (Edema control management)(not mapped)ICHI has no code representing the management of edema control as a clinical activity; no results were found for fluid management, wound management, or edema-specific management.
440329005 (Education about brachycephaly)(not mapped)ICHI does not contain a code for education about brachycephaly or cranial shape deformities; the classification lacks education codes at the level of specific diagnoses or skull morphology conditions.
741054000 (Education about child health surveillance)(not mapped)ICHI does not contain a code for child health surveillance or education about it; the public health surveillance codes concern environmental and population topics rather than developmental monitoring of individual children.
710880004 (Education about dying process)(not mapped)ICHI contains no codes for dying, death, palliative care, end-of-life, bereavement, or terminal care education; this educational intervention has no reasonable ICHI equivalent.
699825005 (Education about electroconvulsive therapy)(not mapped)ICHI has no education codes related to ECT, brain stimulation therapy, or psychiatric treatment procedures; the procedure code AAA.SC.BP represents the ECT procedure itself, not education about it.
370812009 (Education about expected sequence of events)(not mapped)No ICHI code covers patient education about the expected sequence of clinical events or a care pathway; ICHI's education codes are anchored to specific body functions, behaviours, or environmental targets.
429523005 (Education about genitourinary disorder)(not mapped)ICHI contains separate education codes for urinary functions (NT2.PM.ZZ) and sexual/reproductive functions (NUA.PM.ZZ), but no single code covering patient education about genitourinary disorders as a general category. The anatomical block BlockL3-NAA is not assignable and the catch-all NZZ.ZZ.ZZ represents an unspecified procedural intervention, not an educational one.
698607009 (Education about head injury)(not mapped)ICHI's A-prefix education codes cover mental and cognitive functions (awareness, orientation, memory, etc.) rather than anatomical injury or trauma, and there is no education code addressing head or brain injury specifically. The structural interventions on the brain (AAA blocks) are surgical/diagnostic categories, not patient education.
780826002 (Education about hepatitis)(not mapped)ICHI has no education code for viral or infectious liver disease; the nearest candidate DTB.PM.ZZ (education about functions of the immunological system) addresses immune function broadly and not a specific infectious disease, making it too distant to constitute even an inexact match.
698630003 (Education about orthopedic traction)(not mapped)ICHI contains no education code for traction or orthopedic treatment techniques; the PM (education) action axis is applied to body functions, activities, environmental factors, and health behaviours, none of which map specifically to traction as a clinical technique. The nearest musculoskeletal education codes (e.g., MTB.PM.ZZ — joint mobility) address body functions, not the treatment method itself.
717063004 (Education about perioperative injury)(not mapped)ICHI has no education code addressing perioperative injury, surgical safety, or procedure-related complications; the PM (education) action is applied to body functions, activities, environmental factors, and health behaviours, and no target axis entity corresponds to perioperative injury as a domain. UEP.PM.ZZ (health services, systems and policies) and SMH.PM.ZZ (looking after one's health) are too remote to constitute a reasonable match.
2458006 (Educational therapy)(not mapped)ICHI has no assignable category for "educational therapy" as a general therapeutic modality; only body-system-specific "education about [function]" codes exist, none of which captures this broad concept. The action axis value PM (Education) is not an assignable intervention code.
43928007 (Egg inoculation)(not mapped)Egg inoculation is a laboratory/vaccine-manufacturing technique performed on embryonated eggs, not a health intervention on a person; ICHI does not cover laboratory production methods and returned no results for inoculation or related procedures.
180330004 (Electrical carotid sinus stimulation)(not mapped)ICHI has no code for electrical stimulation of the carotid sinus (a baroreflex activation therapy for hypertension); the closest hits — "Carotid artery sinus electrode" (an extension/device code with no assignable procedure code) and general electrical stimulation codes — do not capture this concept. No assignable ICHI category exists for this specific procedure.
1351586005 (Electrically stimulated intravesical therapy)(not mapped)ICHI has no code for electrically stimulated intravesical drug delivery (a technique combining electrical stimulation with intravesical instillation to enhance bladder wall absorption); the only intravesical ICHI code (DTB.DB.AD) is specifically for immunological agents and does not capture the electrical stimulation component, and no bladder stimulation or electromotive drug administration code exists in the classification.
307272003 (Electrocauterization)(not mapped)ICHI is structured around target + action + means and contains no site-independent technique category for electrocauterization as a standalone intervention. The concept describes a modality (electrical cautery) rather than a complete procedure with a defined target, so no assignable ICHI code or block represents it at this level of abstraction.
239350005 (Electromagnetic bone stimulator procedures)(not mapped)ICHI contains no code for electromagnetic or electrical bone stimulation (used to promote fracture healing or osteogenesis); extensive searching across stimulation, bone, electromagnetic, and physical therapy terms returned no relevant match, and fuzzy search yielded only unrelated electrical stimulation codes (pain, pelvic floor, muscle).
69782000 (Electron probe scan)(not mapped)An electron probe scan (electron probe microanalysis/X-ray microanalysis) is a laboratory analytical technique used to determine elemental composition of specimens — it falls entirely outside ICHI's scope, which covers health interventions rather than laboratory bench techniques. No remotely fitting ICHI category exists.
814007 (Electrophoresis measurement)(not mapped)ICHI has no code for electrophoresis as a laboratory analytical technique; the closest candidate (DTA.AB.ZZ "Measurement of haematological system functions") is far too broad and targets a functional domain rather than the specific biochemical separation method. No reasonable ICHI match exists for this laboratory measurement procedure.
438515009 (Email encounter from caregiver)(not mapped)ICHI does not represent asynchronous electronic messaging encounters as standalone assignable codes; the telehealth extension codes (XG block) are qualifier extensions rather than primary intervention codes and do not capture the specific concept of an email-based encounter from a caregiver.
438516005 (Email encounter to caregiver)(not mapped)As with the corresponding "from caregiver" concept, ICHI has no assignable code for an asynchronous email encounter directed to a caregiver; the telehealth extension codes exist only as modality qualifiers and cannot stand alone as a primary code.
233334009 (Embolization of arterial graft)(not mapped)ICHI does not classify interventions on arterial grafts (prosthetic or biological conduits) as a distinct target; no embolisation or occlusion code exists for vascular grafts in the ICHI classification.
432691003 (Embolization using fluoroscopic guidance with contrast)(not mapped)ICHI encodes embolization by anatomical target (e.g. IED.LA.AF for pelvic vein, IEA.LA.AF for pelvic artery), not by imaging modality used for guidance; there is no target-neutral "embolization by fluoroscopy" code, and fluoroscopic guidance with contrast does not correspond to any distinct ICHI category or extension code.
431805002 (Embolization using ultrasound guidance)(not mapped)As with fluoroscopic guidance, ICHI organises embolization codes around the anatomical target rather than the imaging modality used for guidance; a modality-only concept without a defined anatomical target has no corresponding ICHI category or valid extension code.
275608003 (Emergency treatment registration)(not mapped)"Emergency treatment registration" is an administrative intake/documentation process rather than a clinical intervention; ICHI does not cover administrative registration acts, and no equivalent code or close structural match exists in the classification.
47062006 (Employee health culture)(not mapped)"Employee health culture" denotes an organisational or cultural concept within occupational health rather than a discrete health intervention; while ICHI covers workplace safety behaviours (BlockL4-VCB) and work/employment activities (BlockL4-SU2), none of these codes capture the concept of cultivating or assessing an organisational health culture, leaving no reasonable single-code match.
236882000 (Endometrial washing)(not mapped)No ICHI code exists for endometrial washing/irrigation; the irrigation codes in ICHI cover other anatomical sites (vagina, colon, joints, etc.) but not the endometrium specifically, and the uterus block contains no irrigation or lavage category. The procedure is too specific and anatomically targeted to map to a generic or vaginal irrigation code without losing clinical meaning.
117640003 (Endophyte identification)(not mapped)An endophyte is a plant-dwelling fungus or microorganism, and identification of endophytes is a botanical/environmental microbiology procedure not within the scope of ICHI health interventions. The closest ICHI extension code (XG6201) is a laboratory extension modifier, not a standalone intervention code, and does not cover plant endophytes in a clinical context.
53767003 (Endoscopic biopsy)(not mapped)ICHI does not have a single generic "endoscopic biopsy" category code — every endoscopic biopsy code in ICHI is site-specific (bronchus, stomach, colon, prostate, etc.), so the unqualified, body-site-agnostic SNOMED concept has no valid single ICHI counterpart; mapping to any site-specific code would be narrower and misleading.
235157009 (Endoscopic brushings of GIT)(not mapped)ICHI does not contain a code for endoscopic brushings (cytological brush specimen collection) of the gastrointestinal tract; specimen collection codes in ICHI do not extend to GI tract brushings and no sufficiently close approximation exists.
1351728005 (Endoscopic destruction of lesion)(not mapped)ICHI does not have a body-site-agnostic "endoscopic destruction of lesion" category — every endoscopic destruction code requires a specific target organ. This SNOMED concept is a high-level grouper with no assignable ICHI equivalent.
1145178004 (Endoscopic procedure of head and neck)(not mapped)This SNOMED concept is a high-level grouping category covering any endoscopic procedure across all head and neck structures; ICHI has no single code or block that represents this cross-anatomical, action-agnostic grouping.
179868005 (Endoscopic reattachment of intra-articular ligament)(not mapped)ICHI only has arthroscopic reattachment codes for ligaments of the shoulder, elbow, and wrist; there is no reattachment code for a generic joint or for knee ligaments (intra-articular ligaments such as the cruciate).
41073006 (Endoscopy and fulguration)(not mapped)ICHI encodes endoscopic destruction procedures only at specific anatomical sites and has no site-agnostic "endoscopic fulguration/destruction" NEC category.
39836006 (Endoscopy and washing)(not mapped)ICHI does not have a combined "endoscopy and washing/irrigation" procedure code as a single entity; endoscopic irrigation codes exist only for specific anatomical sites and none captures the generic concept.
709011005 (Endoscopy care)(not mapped)"Endoscopy care" is a nursing/procedural care concept that does not correspond to any specific ICHI intervention code; ICHI has no category representing peri-endoscopy care as a distinct intervention type.
50670005 (Endoscopy of carotid body)(not mapped)The carotid body (a chemoreceptor paraganglion) has no dedicated ICHI intervention block or code; ICHI covers carotid artery interventions but not the carotid body itself.
74735006 (Endoscopy of penis)(not mapped)ICHI has no code for endoscopy or diagnostic inspection of the penis; the BlockL5-NGM (Interventions on penis) contains only therapeutic procedures with no endoscopic or diagnostic inspection equivalent. No reasonable ICHI match exists.
709491003 (Enrollment in clinical trial)(not mapped)ICHI does not contain a code for enrolling a patient in a clinical trial; searches for "clinical trial," "enrollment," "research participation," and related administrative/health-service terms returned no relevant results, and no appropriate block was found in the health-services or environment sections.
238224001 (Enucleation of lesion of abdominal wall)(not mapped)The ICHI abdominal wall block (PAL) contains no local or partial excision code — only repair, reconstruction, drainage, and debridement; the nearest candidate (PAK.JI.AA) describes intra-abdominal lesion excision, which is anatomically distinct from the abdominal wall itself.
21808008 (Environmental culture)(not mapped)"Environmental culture" is a microbiology procedure — collecting and culturing samples from the environment (air, surfaces, water) to detect microorganisms. ICHI does not contain a code for laboratory culturing of environmental specimens; its environment-related interventions cover public health actions (remediation, modification, surveillance) rather than diagnostic microbiology sampling of environmental media.
76978006 (Enzyme-linked immunosorbent assay)(not mapped)ICHI does not contain a code for ELISA as a generic laboratory technique; the XG1 essential laboratory tests block contains only specific named tests (e.g., alpha-fetoprotein immunoassay, rapid immunoassay for viral proteins) and none represents the general ELISA methodology. No broader "immunoassay" or "enzyme-linked" category exists in ICHI.
120010002 (Epididymis destructive procedure)(not mapped)ICHI contains no dedicated epididymis destruction code and no epididymis-specific block; the only epididymis reference in ICHI is an anatomy extension code (XA4D25) used for coding specificity, not an assignable intervention code. No code in the male genital system blocks adequately represents destruction of the epididymis specifically.
406839000 (Erie garnet stain method)(not mapped)ICHI does not contain codes for specific histological staining methods or techniques; the only relevant extension code XG30Q5 (Histopathology) is a non-assignable extension descriptor, not an intervention category. Erie garnet is a highly specific dye-based staining protocol with no ICHI equivalent at any level of granularity.
406840003 (Eriochrome blue black SE stain method)(not mapped)As with other named stain methods, ICHI does not represent individual histochemical staining techniques as assignable intervention codes. Eriochrome blue black SE is a specific mineral-staining method used in histopathology, and no ICHI category or block corresponds to this level of laboratory procedure specificity.
406841004 (Erythrosin B stain method)(not mapped)Erythrosin B is a specific fluorescent dye used as a histological counterstain, and ICHI contains no assignable codes for named staining techniques or methods. The extension code XG30Q5 (Histopathology) is not an assignable intervention category and therefore cannot serve as a valid mapping target.
406842006 (Erythrosin Y stain method)(not mapped)ICHI contains no codes for histological staining techniques or dye-based laboratory methods; erythrosin Y is a specific histochemistry stain with no corresponding ICHI procedure category. The only remotely related code (XG30Q5 Histopathology) is an ICD-11 extension/supplementary code, not an assignable ICHI intervention.
1303994008 (Esophagogastroduodenoscopy with repair of duodenum using suture)(not mapped)ICHI contains no endoscopic suture or endoscopic repair code for the duodenum; the available duodenal repair codes (KBI.MK.AA = closure of fistula, KBI.ML.AA = reconstruction) are all open surgical procedures with different actions, and none capture the specific combination of EGD approach with suture closure of the duodenum.
699388000 (Euthanasia education, guidance and counseling)(not mapped)ICHI contains many counselling and education codes, but none addressing euthanasia, assisted dying, or end-of-life decision-making as a subject of intervention. No ICHI code covers this specific clinical/ethical topic area, even approximately.
104248003 (Eutrophication)(not mapped)Eutrophication as a SNOMED procedure concept (whether meaning nutritional supplementation or an environmental analogue) has no corresponding ICHI code; ICHI nutritional administration codes (e.g. PZA.DA.ZZ) cover substance delivery rather than the process of eutrophication itself, and are too semantically distant to constitute even an approximate match.
118441006 (Evacuation of hematoma)(not mapped)ICHI contains no body-site-unspecified "evacuation/drainage of hematoma" code; the only hematoma-specific ICHI code found is PAL.JD.AA (Incision of haematoma of recent laparotomy site), which is far too anatomically narrow. No adequate general match exists.
442334004 (Evaluation of airway equipment condition)(not mapped)ICHI contains codes for inserting/removing/managing airway devices but has no code representing the assessment or condition-check of airway equipment; this is a clinical safety/monitoring activity with no equivalent in ICHI.
370850003 (Evaluation of arterial blood gas studies)(not mapped)ICHI captures specimen collection of blood and assessment of respiration function, but neither represents the clinical act of evaluating arterial blood gas results; interpreting laboratory study findings is outside ICHI's procedure-classification scope.
719033000 (Evaluation of kidney biopsy specimen)(not mapped)ICHI contains codes for performing a kidney biopsy and an extension code for histopathology, but no code exists for the post-procedure laboratory evaluation/analysis of a kidney biopsy specimen as a standalone intervention.
442724006 (Evaluation of nonsurgical biopsy specimen)(not mapped)ICHI classifies biopsy procedures and has a histopathology extension code, but no standalone assignable code exists for the post-procedural evaluation/analysis of a nonsurgical biopsy specimen as a discrete health intervention.
370807008 (Evaluation of response to medications)(not mapped)ICHI does not contain a code for evaluating a patient's clinical response to medications as a standalone intervention; the VAD block covers pharmaceutical use behaviours at a population/public health level, and no clinical assessment code exists for therapeutic medication response monitoring.
442709002 (Evaluation of surgical biopsy specimen)(not mapped)ICHI classifies health interventions performed on patients, not laboratory analysis of already-excised specimens; no assignable ICHI code represents histopathological/cytological examination of a surgical biopsy specimen, and the XG extension codes are supplementary descriptors rather than standalone intervention codes.
406843001 (Evans blue stain method)(not mapped)ICHI contains no codes for histological staining methods or laboratory dye techniques such as the Evans blue stain. This is a research/laboratory method rather than a classifiable health intervention in ICHI's scope.
14509009 (Evisceration)(not mapped)"Evisceration" as a general SNOMED concept (prolapse of abdominal contents through a wound) has no corresponding ICHI code; ICHI does not classify wound dehiscence management or bowel evisceration reduction as a named procedure.
446229003 (Evoked potential study)(not mapped)ICHI only contains modality-specific evoked potential codes (dermatometric, somatosensory, visual, auditory) as separate leaf categories with no single assignable code representing a generic unspecified evoked potential study; the SNOMED concept is a broad grouping that cannot be faithfully collapsed to any one of these specific ICHI codes.
26055001 (Evoked stimulus response testing)(not mapped)Like "Evoked potential study," this concept is a broad umbrella for testing responses to stimuli across multiple sensory and neural pathways; ICHI provides only modality-specific leaf codes (e.g., BTB.AF.BP for visual evoked potentials, CTB.AF.ZZ for auditory) with no single assignable code representing the generic parent concept.
386290007 (Examination assistance)(not mapped)"Examination assistance" refers to a supportive role in facilitating a clinical examination (e.g., helping position or prepare a patient) rather than performing an examination itself; ICHI contains no code for this assistive activity, and the physical examination codes describe the examination procedure itself, not the act of providing assistance with it.
430509005 (Examination of fluid specimen)(not mapped)ICHI contains specific specimen collection codes (e.g., pleural fluid, peritoneal fluid, amniotic fluid) but no generic code for examination or analysis of a fluid specimen across all body sites. The SNOMED concept is a general laboratory/pathology action on any fluid specimen, which has no corresponding ICHI category.
52406004 (Excision and reimplantation of organ for extracorporeal surgery)(not mapped)ICHI has no code representing the compound procedure of excising an organ, performing surgery on it outside the body (bench surgery), and then reimplanting it; procurement codes and transplantation codes cover only their individual components, and no composite or NEC code captures this specific technique.
49921005 (Excision and storage of tissue, organ or cells)(not mapped)ICHI has organ- and tissue-specific procurement codes (e.g. NAA.JH.AA for kidney, KCA.JH.AA for liver) but no generic code covering excision plus storage across tissue, organ, or cells as a class; the SNOMED concept is a generic category-level procedure that has no equivalent single ICHI code.
935008 (Excision of bulbourethral gland)(not mapped)ICHI has no specific code for the bulbourethral (Cowper's) gland; the male genital system block (NGA) covers only prostate, seminal vesicle, spermatic cord, scrotum, testis, penis, and the urethra block (NAM) contains no gland excision codes.
1285598000 (Excision of endocrine gland)(not mapped)ICHI codes excision of individual named endocrine glands (thyroid, adrenal, parathyroid, endocrine pancreas) but provides no generic "excision of endocrine gland" code; the residual block EZZ contains only assessment codes.
46852006 (Excision of falciform ligament)(not mapped)The falciform ligament is a peritoneal fold attaching liver to anterior abdominal wall; ICHI has no code for its excision. The peritoneum block (KMA) contains no excision category, and trunk ligament/fascia targets have no associated intervention codes.
264976009 (Excision of fascia of abdomen)(not mapped)ICHI has no dedicated code for excision of abdominal fascia. The abdominal wall block (PAL) contains repair/reconstruction codes but no excision of fascia, and the ligament/fascia of trunk axis has no associated intervention categories.
449266005 (Excision of intracranial vascular structure)(not mapped)ICHI has no specific category code for excision of an intracranial vascular structure; no resection or total excision leaf code exists under either the intracranial artery or intracranial vein blocks.
18245001 (Excision of ischial bursa)(not mapped)ICHI contains no codes for bursectomy or excision of any bursa; bursa-related entries are extension code anatomy terms only (e.g., XA16K5 "Bursa"), not procedure categories.
32438001 (Excision of lesion of carotid body)(not mapped)The carotid body exists in ICHI only as an extension target code (XA0F61), not as the basis of any assignable intervention code; no ICHI category exists for excision of a carotid body lesion.
62499002 (Excision of ligament of joint)(not mapped)ICHI only provides site-specific ligament excision codes (shoulder, elbow, wrist, knee, etc.) and has no generic "ligament of joint" excision code matching the site-nonspecific SNOMED concept.
392022002 (Excision of mass)(not mapped)ICHI organises all excision codes by specific body-site target axis and has no site-unspecified "excision of mass" code; this generic SNOMED concept cannot be meaningfully mapped without site information.
11550001000004102 (Excision of mass of pelvic region)(not mapped)ICHI's pelvic region blocks cover bone, joints, and muscle/soft tissue but none contain an excision code applicable to a generic soft tissue mass of the pelvic region.
66136000 (Excision of Müllerian duct)(not mapped)ICHI contains no code for excision of the Müllerian (paramesonephric) duct or its remnants; the female and male genital system blocks do not include any code for this embryological structure, and synonym searches (paramesonephric duct, vestigial duct, prostatic utricle) yielded no usable candidate.
1084005 (Excision of perinephric cyst)(not mapped)ICHI contains no code for excision or drainage of a perinephric (perirenal) cyst; the perirenal block only has adhesion release codes. The nearest kidney code NAA.JI.AA targets the kidney parenchyma rather than the surrounding perinephric fat/capsule.
300014003 (Excision of thyroglossal fistula)(not mapped)ICHI has no dedicated code for excision of a thyroglossal fistula — the thyroglossal duct appears only as an extension/anatomy code (XA0SH3) with no associated procedure codes, and no fistula-excision codes exist for this structure anywhere in the classification.
171982008 (Excision of thyroglossal tract)(not mapped)ICHI does not contain a procedure code for excision of the thyroglossal tract (the Sistrunk operation); XA0SH3 is only an anatomy extension code, and no excision procedure codes are defined under any thyroid or endocrine block for this structure.
1287826000 (Excision of tissue of carotid body)(not mapped)The carotid body (XA0F61) exists in ICHI only as an anatomy extension code; there are no procedure codes for excision of carotid body tissue anywhere in the classification, including within the carotid artery block.
238237003 (Excision of urachal fistula)(not mapped)ICHI contains no procedure code for excision or repair of a urachal fistula — the urachus appears only as an extension/anatomy code (XA1NC2) with no associated intervention category.
177923007 (Excision of urachus)(not mapped)The urachus appears in ICHI only as an anatomy extension code (XA1NC2) with no associated intervention category for excision. The urinary bladder intervention block covers cystectomy variants but does not include urachus excision.
8253009 (Excision of Wolffian duct)(not mapped)ICHI contains no dedicated code or assignable category for excision of the Wolffian (mesonephric) duct; the Gartner duct is only represented as an anatomical extension target (XA9BM1), and no procedure combining it with an excision action exists in the classification.
8889005 (Excisional biopsy)(not mapped)This SNOMED concept represents a generic, site-independent procedure type (excisional biopsy of any tissue), and ICHI does not contain a generic cross-site biopsy category; all ICHI biopsy codes are anchored to a specific anatomical target.
65676004 (Exoantigen test for molds)(not mapped)ICHI contains some specific antigen detection codes but no code covers the exoantigen precipitation technique for mold identification as a procedure or test in the intervention classification. No sufficiently close ICHI category exists for this mycological identification method.
6438007 (Exploration of ciliary body)(not mapped)The block BlockL5-BBD (Interventions on ciliary body) contains only biopsy, destruction, excision, bypass, and repair codes — there is no exploration or examination code for the ciliary body in ICHI.
57366008 (Exploration of muscle)(not mapped)ICHI contains no exploration-of-muscle code; the musculoskeletal chapter includes only specific procedural interventions (incision, excision, repair) on named muscle groups, with no general exploration action.
283045004 (Exploration of muscle of hand)(not mapped)The hand muscle block (MGM) contains 10 codes (division, release, drainage, excision, suture, reconstruction) but no exploration code. The closest related code (MGT.AE.AA) targets tendon sheath, a different structure.
36498001 (Exploration of thoracic artery)(not mapped)ICHI has no exploration (AE) code for the thoracic artery; the IDA block contains only incision, excision, occlusion, dilatation, bypass, and repair codes — no surgical exploration entry.
54607000 (Exploration of thoracic vein)(not mapped)ICHI has no exploration (AE) code for the thoracic vein; the IDB block contains only incision, percutaneous interventions, occlusion, dilatation, repair, and reconstruction — no surgical exploration entry.
171674005 (Exploration of trochlear nerve (IV))(not mapped)The ICHI cranial nerve block (AAN) contains no exploration/inspection code. The peripheral nerve exploration code (ACA.AE.AA) is anatomically incorrect for the trochlear nerve, a cranial nerve.
225128003 (Exposing skin to the air)(not mapped)ICHI does not contain a code for the deliberate therapeutic intervention of exposing skin to air (e.g., wound airing). Closest skin-related codes (dressing, phototherapy, application) do not capture this concept.
443456009 (Expression of comedone)(not mapped)ICHI has no code for manual or instrumental expression/extraction of a comedone; searches across skin lesion excision, skin appendage, drainage, and destruction codes found no semantic match.
118636005 (Expulsion)(not mapped)"Expulsion" is a high-level abstract concept (foreign body, calculus, IUD, obstetric expulsion) without a specific body site or technique; no single ICHI code covers this generic action.
59719002 (Exteriorization)(not mapped)"Exteriorization" as a standalone, non-site-specific concept has no corresponding generic code in ICHI; ICHI is procedure- and anatomy-specific and lacks a body-system-agnostic exteriorization concept.
33195004 (External beam radiation therapy procedure)(not mapped)ICHI's radiotherapy codes are all site-specific (brain, breast, prostate, etc.) with no general "external beam radiation therapy" category; the SNOMED concept describes the technique class as a whole across all sites.
120134009 (External ear injection)(not mapped)The external ear block (CAA/CAC/CAE) contains no injection category; the only ear injection code in ICHI refers to the inner ear, which is anatomically inappropriate.
87663001 (External fetal monitor surveillance during multiple pregnancy)(not mapped)The only fetal monitoring code in ICHI is NMR.AI.AC (Internal fetal monitoring) — the opposite invasive approach — and no external or multiple-pregnancy-specific code exists.
233574002 (Extracorporeal carbon dioxide removal)(not mapped)ICHI contains no code for extracorporeal CO2 removal (ECCO2R), a specialized respiratory support technique distinct from ECMO and not represented under dialysis, apheresis, or ventilation categories.
1263392007 (Extracorporeal irradiation of tumor bearing bone and reimplantation)(not mapped)ICHI has no code representing ex vivo irradiation of a resected tumor-bearing bone followed by reimplantation; closest candidates capture only one isolated step.
288182009 (Extracorporeal kidney)(not mapped)"Extracorporeal kidney" (bench surgery) is a composite procedure (removal, ex vivo reconstruction, reimplantation) with no dedicated ICHI code; closest candidates each capture only one component.
241723004 (Eye protection using goggles or spectacles)(not mapped)ICHI contains no code for provision or use of protective eyewear (goggles or spectacles) as a clinical intervention; this concept sits outside the clinical procedure scope of ICHI and there is no environmental or personal protective equipment code applicable.
444225007 (Factor II (prothrombin) G20210A mutation detection)(not mapped)ICHI contains a code for prothrombin time/INR, which is a functional coagulation assay, but there is no ICHI code for molecular mutation detection of the prothrombin G20210A variant; this level of molecular genetic specificity is not represented in the classification.
103804006 (Factor V inhibitor assay)(not mapped)ICHI does not contain any code for a Factor V inhibitor assay or for coagulation factor inhibitor testing generally; the essential laboratory block covers PT and PTT but not specific coagulation factor inhibitor measurement.
165606004 (Factor V Leiden genotype)(not mapped)ICHI has no code for Factor V Leiden genotyping or any thrombophilia genetic test; molecular genotyping assays for specific variants are not represented in the classification.
103805007 (Factor VII inhibitor assay)(not mapped)ICHI's "Essential laboratory tests" extension block contains coagulation-related tests such as partial thromboplastin time and prothrombin time, but does not include specific individual coagulation factor inhibitor assays.
52377006 (Factor VIII C: Ag assay)(not mapped)No ICHI code exists for a Factor VIII antigen or activity assay; the classification does not enumerate individual coagulation factor assays. The closest available codes (PTT, prothrombin time) measure global coagulation pathway function, not a specific factor antigen.
413021006 (Factor VIII inhibitor screening test)(not mapped)ICHI lacks any code for screening of inhibitors against a specific coagulation factor such as Factor VIII. The partial thromboplastin time is used as a preliminary indicator in clinical practice but is a fundamentally different test.
103806008 (Factor X inhibitor assay)(not mapped)No ICHI code covers a Factor X inhibitor assay; the classification does not descend to the level of individual coagulation factor inhibitor measurement.
103807004 (Factor XI inhibitor assay)(not mapped)ICHI provides no code for a Factor XI inhibitor assay. The classification's coagulation-related entries are limited to global screening tests (PTT, prothrombin time/INR) and do not reach individual factor inhibitor testing.
414191008 (Fall risk assessment)(not mapped)ICHI does not contain a dedicated fall risk assessment code; the closest candidates (gait assessment, general health assessment) do not capture the specific clinical intent of a multifactorial fall risk evaluation.
274469009 (Fascia stretching)(not mapped)ICHI contains fascia codes only in the surgical domain (excision, release, reattachment of ligament/fascia), and no rehabilitation or functional code exists that targets fascia with a stretching or passive/active elongation action; the closest musculoskeletal exercise codes (e.g. MTB.PG.ZZ) target joint mobility rather than fascia tissue specifically.
187528002 (Fasciodesis)(not mapped)Fasciodesis is the surgical attachment of fascia to a bone or tendon to stabilise a joint, a concept distinct from arthrodesis (bone fusion), tenodesis (tendon fixation), or simple fascia lengthening. No ICHI code captures fascial stabilisation of a joint at an unspecified site, and no close enough approximation exists without misrepresenting the procedure.
178071007 (Fasciotomy forearm)(not mapped)The MFL block ("Interventions on ligament or fascia of forearm") contains no incision or division of fascia code — its children address "wrist" structures and do not include a fasciotomy/incision of the forearm fascia proper; no assignable ICHI category adequately represents fasciotomy of the forearm.
178070008 (Fasciotomy upper arm)(not mapped)Although ICHI has a block "Interventions on ligament or fascia of upper arm" (BlockL5-MEJ) and the target axis code MEL (Ligament or fascia of upper arm), no assignable procedure codes for incision or division of fascia of the upper arm exist under that block; only Release/Reattachment/Excision codes for elbow and shoulder regions are present.
406844007 (Fast blue B salt stain method)(not mapped)This SNOMED concept represents a specific histochemical staining reagent protocol (Fast blue B salt, used in enzyme histochemistry). ICHI does not classify individual laboratory staining methods or histochemical techniques at this level of granularity; no corresponding code exists anywhere in the classification.
406845008 (Fast blue BB salt stain method)(not mapped)Like Fast blue B salt, this is a specific histochemical staining method (Fast blue BB salt, another diazonium salt used in enzyme cytochemistry). ICHI lacks codes for individual laboratory staining reagent methods, making any mapping impossible.
406846009 (Fast blue RR salt stain method)(not mapped)Fast blue RR salt is a further variant histochemical staining reagent (used e.g. for ATPase reactions in muscle biopsies). ICHI does not classify staining reagent techniques at this level of specificity, and no reasonable ICHI code exists for this concept.
406847000 (Fast garnet GBC salt stain method)(not mapped)ICHI contains no codes for specific histochemical staining reagent methods. Fast garnet GBC salt is an azo dye used in enzyme histochemistry (e.g., for alkaline phosphatase), a level of analytical granularity that ICHI does not represent — the nearest candidates (XG30Q5 Histopathology, XG1640 Immunohistochemistry) are semantically distinct procedure categories.
406848005 (Fast green FCF stain method)(not mapped)Fast green FCF is a synthetic food/tissue dye used in counterstaining and collagen differentiation protocols; ICHI has no code for specific staining reagent methods at this level of specificity, and no broader staining category exists that would constitute even a "wider" match without being semantically misleading.
406849002 (Fast red B salt stain method)(not mapped)Fast red B salt is a diazonium salt used as a coupling agent in azo dye enzyme histochemistry; ICHI does not classify specific staining reagent procedures, and no ICHI code covers this class of method even at a broader level.
406850002 (Fast red ITR stain method)(not mapped)Fast red ITR is a specific azo dye variant used in histochemical enzyme demonstration; like the other fast dye methods in this group, it has no corresponding ICHI code, as ICHI does not enumerate individual staining reagent techniques.
406851003 (Fast red TR salt stain method)(not mapped)Fast red TR salt is a diazonium compound used in histochemical staining (notably for acid phosphatase and esterase); ICHI classifies health interventions at the level of procedure types rather than specific reagent-defined techniques, leaving this concept without a mappable ICHI counterpart.
7288006 (Febrile agglutinins, qualitative)(not mapped)Febrile agglutinins is a panel of qualitative bacterial agglutination antibody tests (Salmonella, Brucella, Francisella, Rickettsia) used in fever workup. ICHI contains only Treponema pallidum agglutination codes and no code covering bacterial febrile agglutinin panels or their equivalent concept.
59681003 (Fecal urobilinogen, quantitative)(not mapped)ICHI contains no code for urobilinogen measurement (fecal or urinary), and the Essential Laboratory Tests block does not include this analyte; no sufficiently related code exists in ICHI to constitute even an approximate match.
410336000 (Feeding procedures case management)(not mapped)ICHI has no concept corresponding to case management as an organisational/coordinating intervention; searches for "case management", "feeding procedures", and "care plan" returned no results, and no appropriate ICHI category covers coordinated management of feeding procedures as a distinct administrative activity.
1269479003 (Female perineal care management)(not mapped)"Female perineal care management" denotes a nursing hygiene management activity with no ICHI equivalent; ICHI perineum codes (PAW block) cover surgical interventions only, and hygiene behaviour codes (VED block) target public-health education rather than bedside clinical care management.
406855007 (Feulgen reaction stain method)(not mapped)The Feulgen reaction is a specific histochemical staining technique used in laboratory analysis to detect DNA; ICHI does not classify laboratory staining methods at this level of granularity.
89226006 (Fibrinogen inhibitor assay)(not mapped)ICHI does not classify in-vitro laboratory analytical tests such as coagulation factor assays; this falls outside the scope of ICHI, which covers health interventions on persons rather than laboratory analysis of specimens.
406856008 (Field's stain method)(not mapped)Field's stain is a laboratory staining technique applied to blood smears (primarily for malaria); ICHI contains no codes for staining methods, microscopy techniques, or in-vitro diagnostic procedures.
17662004 (Filleting)(not mapped)"Filleting" as a standalone SNOMED concept is an extremely generic surgical technique (stripping soft tissue from bone to create a flap) with no anatomical site specified; ICHI has no corresponding procedure concept at this level of abstraction.
395103003 (Final days pathway)(not mapped)ICHI has no concept corresponding to a "final days pathway" (a structured end-of-life care protocol such as the Liverpool Care Pathway); palliative care pathways and end-of-life care coordination are not represented as distinct ICHI codes.
8150002 (Fine needle aspirate with immediate interpretation and report)(not mapped)ICHI contains site-specific aspiration codes but no generic "fine needle aspiration" code that captures the procedure irrespective of site, nor any code that incorporates immediate on-site cytological interpretation and reporting.
442787002 (Fine needle aspiration biopsy using imaging guidance)(not mapped)ICHI encodes biopsies by target organ rather than by technique (FNA) or guiding modality (imaging guidance). No cross-organ FNA code or imaging-guided biopsy category exists in ICHI.
64280007 (Fitting of artificial limb)(not mapped)ICHI contains supplementary entries for "Upper limb prostheses" and "Lower limb prostheses" but these carry no assignable intervention code; no ICHI category code for fitting or dispensing an external limb prosthesis could be identified.
427517005 (Fitting of dynamic cranioplasty band)(not mapped)ICHI has no code for fitting a dynamic cranial remodelling orthosis (helmet) to the skull. The only related code, MAA.KB.AH, refers to replacement of rigid immobilisation devices and there is no initial-application equivalent for the skull.
735926002 (Fitting of external breast prosthesis)(not mapped)The breast block covers only surgical/internal-implant procedures; no ICHI code exists for fitting a non-surgical external breast prosthesis (worn after mastectomy). Although a structural parallel exists for other body parts (e.g., NGM.DP.AH for external penile prosthesis), no equivalent breast code is present.
426647008 (Fitting of external hearing prosthesis to bone anchored fixtures)(not mapped)ICHI encodes cochlear implant management and middle-ear prosthetic device management, but fitting an external sound processor to an osseointegrated bone-anchored hearing fixture is a distinct intervention not captured by either code; the bone-anchored hearing system appears only as a product/extension code without a corresponding intervention category.
1286813007 (Fitting of extraoral maxillofacial prosthesis)(not mapped)ICHI contains no code for fitting external (epiprosthetic) maxillofacial prostheses such as nasal, orbital, or auricular prostheses; all maxillofacial blocks cover only surgical interventions on bone and tissue, with no external prosthesis fitting category for the face.
78254001 (Fitting of spectacles, bifocal)(not mapped)ICHI does not contain an assignable code for fitting or prescribing spectacles of any type. The "Spectacles; low vision, short distance, long distance, with filters and protection" item in ICHI has no code assigned and no other visual system code covers the clinical act of fitting corrective spectacles.
19279009 (Fitting of spectacles, low vision aid, single element)(not mapped)As with bifocal spectacle fitting, ICHI has no assignable procedure code for fitting low vision spectacles; no code in the visual system chapter (BAA–BZZ) captures the act of prescribing or fitting low vision spectacle aids.
239279000 (Fixation of fracture)(not mapped)ICHI codes fracture reduction and fixation only at specific anatomical sites (skull, spine, humerus, femur, etc.) and does not have a generic unspecified-site "fixation of fracture" category; no single ICHI code covers the full breadth of this site-unspecified SNOMED concept.
406857004 (Flagellar stain method)(not mapped)Flagellar staining is a specialist microbiological laboratory technique used to visualise bacterial flagella; ICHI does not include staining methods or general histology/microbiology bench techniques, and the Essential Laboratory Tests extension block contains only selected clinical assays with no staining procedures.
118478009 (Flexor muscle origin slide procedure)(not mapped)ICHI has no code representing a muscle origin slide (the surgical technique of detaching and distally repositioning a muscle's origin to lengthen or relieve a contracture). The closest structural concepts — muscle division, muscle transfer/transplantation, and reconstruction of forearm muscle — each describe fundamentally different operations and would misrepresent this specific procedure.
29274000 (Flow cytometry, cell cycle analysis)(not mapped)ICHI contains only one flow cytometry code (XG5FX1, "Essential flow cytometry panel of antibodies for leukaemia"), which is specific to antibody panels for leukaemia and does not cover cell cycle analysis by flow cytometry. No broader laboratory investigation code in ICHI adequately represents this analytical procedure.
50183007 (Flow cytometry, cell marker analysis)(not mapped)The only ICHI flow cytometry code (XG5FX1) is scoped to an essential antibody panel for leukaemia diagnosis, while cell marker analysis by flow cytometry is a broader immunophenotyping technique applicable across many conditions. No ICHI code adequately covers this concept.
85817005 (Flow cytometry, DNA analysis)(not mapped)ICHI has no code for DNA content analysis by flow cytometry (e.g., ploidy or S-phase fraction measurement). The single ICHI flow cytometry code (XG5FX1) is restricted to antibody panels for leukaemia and is semantically unrelated to DNA analysis.
430147008 (Fluid balance monitoring)(not mapped)ICHI contains specific monitoring codes for particular body sites or parameters (blood pressure, EEG, fetal, compartment pressure, etc.) but no code representing general fluid balance or intake/output monitoring. No reasonable approximation exists within ICHI at a level that would not substantially misrepresent the concept.
121340002 (Fluorocarbon identification)(not mapped)ICHI does not contain codes for chemical compound identification procedures such as fluorocarbon (organofluorine compound) analysis or toxicological identification; the classification's laboratory section (XG1) covers only essential clinical tests and does not include analytical chemistry or toxicological substance identification methods.
1251649003 (Fluoroscopic discography with injection of contrast into intervertebral disc)(not mapped)ICHI contains no discography or contrast injection code for any intervertebral disc level; the entire disc imaging/injection category is absent from the classification, leaving no reasonable code to assign.
1204278004 (Fluoroscopy guided cryoablation of lesion)(not mapped)ICHI has no concept for cryoablation as a distinct modality, and the SNOMED concept does not specify a body site, making it unclassifiable under any target-specific ICHI destruction code. No ICHI code captures both the cryoablation technique and the unspecified-site lesion with fluoroscopic guidance.
710291004 (Fluoroscopy guided endoscopy)(not mapped)ICHI does not contain a generic code for fluoroscopy-guided endoscopy as a procedure class — the ICHI endoscopy codes are all organ-specific (e.g., small intestine, paranasal sinus, rectum) and none captures this as a modality-defined, anatomy-unspecified intervention.
719499006 (Fluoroscopy guided ethanol ablation)(not mapped)Ethanol (chemical) ablation guided by fluoroscopy has no direct ICHI counterpart — ICHI destruction codes are organ-specific (e.g., liver, spinal nerve) and there is no generic "percutaneous injection of destructive agent" code, nor any fluoroscopy-guided chemical ablation category, making a reasonable body-system-neutral mapping impossible.
771093003 (Fluoroscopy guided localization of lesion with diagnostic dye)(not mapped)ICHI contains no code for image-guided pre-procedural lesion localisation using a diagnostic dye or marker injection; this technique (e.g., wire/dye marking before surgery) has no equivalent in the ICHI classification.
713601002 (Fluoroscopy guided measurement of pulp pressure of spleen)(not mapped)ICHI contains no haemodynamic or parenchymal pressure measurement code for the spleen; the spleen block (DJA) covers biopsy, drainage, excision, and scan/function study but not splenic pulp pressure measurement, and no NEC code in the vascular or digestive pressure category covers this procedure.
702676007 (Fluoroscopy guided pancreatic venous sampling with contrast)(not mapped)ICHI contains no code for selective venous sampling from pancreatic veins; the portal vein block (IEF) covers interventions on the portal vein and branches but has no aspiration/sampling code, and the pancreas block (KCO) has no venous access or blood sampling code, leaving this SNOMED concept without a reasonable ICHI equivalent.
711207003 (Fluoroscopy guided puncture of cyst)(not mapped)ICHI does not contain a generic "puncture of cyst" code — cyst drainage codes exist only for specific anatomical targets (orbit, gallbladder, bladder, etc.) and none covers a body-site-unspecified fluoroscopy-guided cyst puncture.
1264385008 (Follow-up for combined therapy of surgery, radiation therapy, and chemotherapy)(not mapped)ICHI contains no code for post-treatment surveillance or follow-up encounters, nor for multimodal oncology follow-up specifically; this SNOMED concept describes a monitoring activity after combined cancer therapy that has no equivalent ICHI category.
370858005 (Following clinical pathway protocol)(not mapped)ICHI classifies health interventions by action on body targets and does not include administrative or organisational acts such as adhering to a clinical pathway protocol; no ICHI code corresponds to this process/coordination concept.
385957006 (Foot care management)(not mapped)"Foot care management" is a holistic nursing/podiatric concept encompassing inspection, hygiene, nail care, and skin maintenance; no single ICHI assignable code captures this composite care activity.
182736004 (Forced diuresis)(not mapped)Forced diuresis is a clinical protocol involving high-volume IV fluid infusion combined with diuretic administration; ICHI contains no code for this intervention or its component steps at a level of specificity that constitutes a reasonable match.
120217006 (Forearm incision)(not mapped)ICHI's skin/subcutaneous block for the upper limb does not include an incision code, and no other forearm-specific incision code exists; while incision codes exist for skin of the trunk and for arteries, no assignable ICHI code maps to a general incision of the forearm.
71257004 (Formation of neurovascular pedicle graft)(not mapped)ICHI has codes for nerve grafts, skin grafts, and pedicle flap (extension), but no assignable category code specifically represents the combined neurovascular pedicle graft procedure carrying both nerve and vessel supply.
20526009 (Formation of syndactyly of toe)(not mapped)Formation of syndactyly (intentional surgical creation of toe webbing, used in reconstructive procedures) has no equivalent in ICHI; the classification covers syndactyly repair/release but not its deliberate surgical creation.
228580000 (Forward chaining technique)(not mapped)Forward chaining is a specific behavioural intervention technique (sequential task-step reinforcement used in ABA and occupational therapy); ICHI does not enumerate individual therapeutic techniques at this level of specificity.
1297069006 (Fractionated dose radiotherapy)(not mapped)ICHI encodes radiotherapy only as site-specific destruction codes and does not have a generic radiotherapy code, nor any axis value to represent dose fractionation as a delivery technique.
1255359001 (Fractionated dose stereotactic radiation therapy)(not mapped)ICHI has no stereotactic radiosurgery or stereotactic body radiotherapy codes, and no means axis value for stereotactic technique or dose fractionation.
385693005 (Fracture care management)(not mapped)ICHI has no overarching fracture care management concept; it only encodes specific fracture interventions by anatomical site. The SNOMED concept represents a clinical management episode rather than a discrete procedural intervention.
69140008 (Freezing and thawing of culture)(not mapped)This concept refers to a laboratory technique for cryopreservation of biological cultures (cell or microbial), which falls outside the ICHI scope of clinical health interventions.
406863008 (Fuchsin acid stain method)(not mapped)ICHI does not include laboratory staining techniques or histochemistry methods; the classification covers health interventions rather than in-vitro analytical laboratory procedures.
117047004 (Fuchsin basic stain method)(not mapped)ICHI does not cover in-vitro histology or microbiology staining methods such as basic fuchsin (Ziehl-Neelsen-related) staining.
169630005 (Full stay delivery booking)(not mapped)This SNOMED concept represents an administrative/scheduling activity (booking a full inpatient stay for maternity delivery) rather than a clinical health intervention; ICHI does not classify administrative booking or registration activities.
12894003 (Functional assessment)(not mapped)ICHI contains many domain-specific assessment codes but no single assignable code representing a broad, cross-domain "functional assessment" as used in ICF-based clinical practice; the concept is too broad and multi-axial for any single ICHI category.
20543007 (Fungus stain method)(not mapped)ICHI does not include laboratory staining methods as health interventions; no code for fungal (PAS, GMS/Grocott) or any special histological stain exists in the classification.
171189000 (Galactosemia screening)(not mapped)ICHI contains no code for condition-specific metabolic or newborn screening; VDB screening blocks cover public-health behaviours, and no laboratory test code for galactosemia exists.
406864002 (Gallocyanine stain method)(not mapped)Gallocyanine staining is a histochemical laboratory technique; ICHI does not cover laboratory staining methods — its scope is health interventions on persons.
89070007 (General durotomy)(not mapped)ICHI has no incision (FA action) code in either the cerebral meninges (AAC) or spinal meninges (ABC) blocks; durotomy has no assignable counterpart.
65263004 (General radiation therapy consultation and report)(not mapped)ICHI radiotherapy codes are only destructive tissue interventions on specific anatomical targets; there is no concept for a radiation therapy consultation, planning, or clinical report.
765104009 (Geriatric monitoring)(not mapped)ICHI has no geriatric-specific monitoring code and no age-defined population category; existing monitoring codes are organ- or function-specific.
408249001 (Globin gene analysis)(not mapped)ICHI does not contain DNA/gene-level molecular analysis or genetic testing codes; the only genetics-domain code (PYA.PP.ZZ) is genetic counselling, a different intervention type entirely.
171190009 (Gout screening)(not mapped)ICHI has no codes for gout, uric acid, or hyperuricaemia screening; the screening behaviour blocks (VDB) cover population-health screening participation rather than disease-specific clinical screening tests.
1344718008 (Grafting of tissue to ankle)(not mapped)ICHI has no code for grafting tissue to the ankle; the ankle joint block (MNJ) and cartilage block (MNC) contain no generic tissue graft entry, and no bone graft code exists for the ankle as a distinct site.
1335737005 (Grafting of tissue to brain)(not mapped)The brain interventions block (AAA) contains no reconstruction or graft code (ML action), and exhaustive searching found no ICHI category representing any form of tissue grafting to the brain.
85406001 (Grinding of tissue for culture)(not mapped)ICHI does not contain codes for laboratory specimen processing techniques such as tissue homogenization/grinding prior to microbial culture; this is a pre-analytical laboratory procedure outside ICHI's scope.
66910006 (Gross organ fixation and special preparation)(not mapped)This SNOMED concept refers to pathological/autopsy specimen preparation (chemical fixation and special histological staining of whole organs), which is a forensic and pathology laboratory procedure outside ICHI's scope.
422329009 (Hall's bilirubin stain)(not mapped)Hall's bilirubin stain is a specific histochemical staining technique used in pathology to detect bile pigments; ICHI contains no histochemical staining codes or bilirubin-specific laboratory procedures.
121342005 (Halogenated hydrocarbon identification)(not mapped)Halogenated hydrocarbon identification is a forensic or clinical toxicology laboratory procedure for detecting a specific chemical class; ICHI has no codes covering chemical substance identification or toxicological analysis of specific compound classes.
50949001 (Handling of microbiologic test report)(not mapped)ICHI does not contain codes for administrative/informational acts such as processing or handling a laboratory or microbiologic test report; the classification focuses on clinical interventions, rehabilitation, and public health actions.
432138007 (Handoff communication)(not mapped)ICHI has no code representing clinical handoff or care transition communication between providers; while UEP.TD.ZZ exists, it is a public-health policy-level concept that is semantically too distant from the specific clinical workflow act.
309096008 (Harvest of reproductive tissue)(not mapped)ICHI has no generic "harvest of reproductive tissue" code — the closest analogues are site-specific (oocyte retrieval, sperm procurement), but none covers the broader concept of harvesting reproductive tissue in general.
1279670007 (Harvesting of cornea)(not mapped)The cornea block (BlockL5-BBB) contains no procurement or harvesting code; the available cornea codes cover transplant, repair, biopsy, and excision of lesions, but none represent donor-side harvesting of the whole cornea for graft purposes.
385824008 (Health history taking education)(not mapped)ICHI has no code for educating patients or clinicians in health history-taking techniques; the closest concepts are interview/whole-person assessment and health literacy education, neither of which captures education about history-taking as a skill.
385825009 (Health history taking management)(not mapped)ICHI does not contain a code for the management or coordination of health history-taking activities; "management" in ICHI is reserved for device or appliance management.
265466007 (Heart wall, septum and chamber operations)(not mapped)This SNOMED concept is a high-level grouper covering structural heart operations across wall, septum and chambers; ICHI distributes these across multiple blocks (HFA, HAD/HBD/HFB, HBA/HBZ) with no single code or block matching the full scope.
128970009 (Held ventilation)(not mapped)"Held ventilation" (deliberate breath-hold during imaging or anesthesia) has no corresponding ICHI code — ICHI only has artificial ventilation, a mechanical support intervention rather than a breath-hold technique.
168381002 (Helicobacter blood test)(not mapped)ICHI's essential laboratory test block contains specific serology codes for HIV, hepatitis, dengue and similar conditions but has no code for H. pylori antibody testing or any generic bacterial serology test.
406866000 (Hematoxylin stain method)(not mapped)ICHI does not represent laboratory staining methods such as haematoxylin and eosin (H&E); ICHI covers health interventions on patients or populations, not in-vitro analytical techniques performed on tissue specimens.
414392008 (Herbal therapy)(not mapped)No ICHI code for herbal, phytotherapy, or plant-based therapeutic interventions exists; searches across complementary/alternative medicine, traditional medicine, natural remedies, and related terms returned no usable match, and ICHI's medication codes (UAC axis) refer to pharmaceutical management rather than herbal therapy.
723181002 (Herpesvirus infection prophylaxis)(not mapped)ICHI contains no codes for infection prophylaxis, chemoprophylaxis, or antiviral prevention — these concepts (drug-based preventive regimens) fall outside the ICHI classification scope as currently modelled, and no reasonably related intervention code exists in the classification.
448011006 (High intensity focused ultrasound ablation using ultrasound guidance)(not mapped)This SNOMED concept describes a procedure-type modifier (HIFU performed under ultrasound guidance) without specifying a target body part, making it a technique/approach concept rather than a complete intervention. ICHI codes are always target-anchored; there is no generic cross-organ HIFU-with-guidance code, and no ICHI extension or block captures this modality-only concept in isolation.
235230000 (Highly selective vagotomy with drainage)(not mapped)ICHI contains no vagotomy codes — the classification lacks specific entries for selective or highly selective division of gastric vagal nerve branches. The combined procedure (nerve division plus drainage/pyloroplasty) cannot be meaningfully represented by any single ICHI category, and the closest available code (ACA.FB.AA Division of peripheral nerve) is far too broad to constitute even an approximate match.
288158004 (Hinged traction)(not mapped)ICHI contains only two traction-related codes — MBZ.LC.AE (skeletal traction to the spine) and MAA.DL.AA (insertion of skull tongs/halo device) — neither of which covers hinged traction as an orthopedic technique applied to limb joints or fractures. No ICHI code captures this specific intervention.
182968001 (Homeopathic therapy)(not mapped)ICHI does not include homeopathy, naturopathy, or traditional/alternative medicine treatments as assignable categories; an exhaustive search across text, fuzzy, and block browsing found no relevant code.
185914003 (Hormone replacement monitoring verbal invite)(not mapped)This SNOMED concept describes a verbal invitation/recall reminder — an administrative communication act with no corresponding ICHI intervention category; closest candidates are system-level public health alerts, not individual patient contact.
252312006 (Horse erythrocyte antigen test)(not mapped)ICHI's essential laboratory test block (XG1) covers a curated set of common tests but does not include the horse erythrocyte (equine red cell) antigen test, a specialised immunological/allergological assay.
112690009 (Hospital admission, boarder, for social reasons)(not mapped)This concept describes a non-clinical social admission where an individual is accommodated in hospital for social rather than medical reasons; ICHI does not classify hospital encounter/admission events.
10378005 (Hospital admission, emergency, from emergency room, accidental injury)(not mapped)ICHI does not classify the administrative act of hospital admission; it codes clinical interventions performed on patients, with no ICHI category representing emergency inpatient admission.
19951005 (Hospital admission, emergency, from emergency room, medical nature)(not mapped)Hospital admission is an administrative/organisational event rather than a health intervention in the ICHI sense; no ICHI code covers emergency inpatient admission.
1172821006 (Hospital care)(not mapped)"Hospital care" is a high-level administrative/organisational concept denoting overall delivery of care in a hospital setting; ICHI codes specific health interventions and has no category representing this aggregate concept.
433114000 (Human epidermal growth factor receptor 2 gene detection by immunohistochemistry)(not mapped)ICHI contains XG1640 (Immunohistochemistry) and XG9C48 (HER2 overexpression) only as extension/supplementary codes, not as assignable intervention categories; no ICHI procedure code represents HER2 testing by immunohistochemistry as a distinct intervention.
767147008 (Identification of arsenic and/or arsenic compound)(not mapped)ICHI contains no codes for testing or identifying specific toxic elements or heavy metals such as arsenic; the essential laboratory tests block covers only a narrow set of priority tests with no toxicological analyte identification.
811791000000103 (Identifying barriers to goal achievement)(not mapped)No ICHI code addresses barrier identification in a goal-setting context; closest structural concepts (PZB.TB.ZZ, PZB.AA.ZZ) represent different clinical activities and would misrepresent the mapping.
235306004 (Ileal transposition)(not mapped)Ileal transposition is a composite metabolic surgery (segment excision, repositioning, anastomosis of ileum) with no corresponding ICHI category; available small-intestine codes capture only one component each and would misrepresent the concept.
715964008 (Imaging of lower limb)(not mapped)ICHI contains only vessel-specific imaging blocks (arteries, veins) and scattered joint-specific MRI codes for the lower limb; no block or category covers imaging of the lower limb as a whole.
303746005 (Imaging of nervous system with contrast)(not mapped)ICHI codes contrast imaging for individual nervous system structures (e.g., AAA.BA.BD brain CT with contrast, ABA.BA.BB spinal cord with contrast medium) but provides no aggregate code or block representing imaging of the nervous system as a whole with contrast.
303761006 (Imaging of pancreas with contrast)(not mapped)ICHI only has X-ray (KCO.BA.BA), ultrasound (KCO.BA.BJ), and endoscopic ultrasonography (KCO.BA.AD) for pancreas imaging; CT-with-contrast and MRI-with-contrast codes do not exist, leaving no ICHI code that captures imaging-with-contrast for the pancreas.
1366464005 (Imaging of specimen)(not mapped)ICHI contains no category for imaging performed on an excised specimen (ex vivo radiological examination); specimen-related codes in ICHI are limited to specimen collection procedures, not post-collection imaging.
414459003 (Imaging of upper limb)(not mapped)ICHI's upper limb imaging codes (ICA/ICD blocks) cover only vascular imaging; the musculoskeletal blocks contain scattered bone X-ray codes but no aggregate "imaging of upper limb" category spanning all tissues.
719259006 (Imaging procedure without contrast)(not mapped)ICHI does not have a cross-cutting "imaging without contrast" category; contrast status is encoded in the Means axis of individual anatomy-specific codes, with no structural equivalent for this modality-based grouper.
24846002 (Imbrication)(not mapped)Imbrication (overlapping suture/plication technique) is not represented as a distinct ICHI category; the ICHI Means axis encodes surgical approach but not layered suture technique, and named cardiac plication codes refer to specific structures, not the general technique.
363144009 (Immune system diagnostic imaging procedure)(not mapped)ICHI has no single code or block representing diagnostic imaging across the immune system as a whole; imaging codes for relevant immune tissues are dispersed across individual anatomical targets with no unifying parent.
363145005 (Immune system endoscopy)(not mapped)ICHI contains no endoscopy codes for immune system structures as a group; the lymphatic system block (BlockL4-DFA) and spleen block (BlockL4-DJA) contain no endoscopic procedure codes.
363149004 (Immune system physical examination)(not mapped)ICHI contains no category for physical examination scoped to the immune system; DTB.AA.ZZ covers functional assessment (not a physical exam) and PZX.AE.AH is a non-specific body-site examination, neither captures the SNOMED concept adequately.
363150004 (Immune system procedure by site)(not mapped)This SNOMED concept is a high-level grouper rather than a specific intervention; ICHI has no equivalent administrative grouping category and assigning DTB or DFA blocks would misrepresent the concept's scope.
414464004 (Immunoassay method)(not mapped)ICHI contains only a small number of analyte-specific immunoassay codes (e.g., XG4B05 AFP immunoassay, XG8EX8 rapid immunoassay for viral proteins) and has no generic immunoassay-method category covering the technique as a class.
104417008 (Immunoassay, qualitative, multiple step method)(not mapped)ICHI's immunoassay entries are analyte-specific rather than technique-specific, so there is no ICHI code representing a qualitative, multi-step immunoassay procedure in general.
104419006 (Immunoassay, qualitative, single step method)(not mapped)ICHI has no code representing a generic qualitative immunoassay or single-step methodology; available immunoassay codes are analyte-specific.
104422008 (Immunoassay, quantitative)(not mapped)ICHI does not have a code for a generic quantitative immunoassay method; the Essential laboratory tests block contains only named, analyte-specific tests.
104421001 (Immunoassay, quantitative, by radiopharmaceutical technique)(not mapped)ICHI contains no radioimmunoassay (RIA) or radiopharmaceutical immunoassay code; no ICHI code approaches the specificity of a quantitative RIA technique.
104418003 (Immunoassay, semi-quantitative, multiple step method)(not mapped)ICHI models neither semi-quantitative immunoassay nor multi-step assay methodology; the classification's granularity for laboratory tests is at the analyte level.
104420000 (Immunoassay, semi-quantitative, single step method)(not mapped)ICHI has no code for semi-quantitative or single-step immunoassay methods; these methodology concepts fall outside ICHI's coding granularity.
37310002 (Immunoblot assay)(not mapped)ICHI contains no code for immunoblot (Western blot) techniques; the Essential laboratory tests block does not represent immunoblot as a procedure class.
414465003 (Immunochemiluminometric assay)(not mapped)ICHI has no code for chemiluminescent or luminometric immunoassay techniques; only analyte-specific immunoassay codes are available.
32623009 (Immunodiffusion measurement)(not mapped)ICHI contains no code for immunodiffusion techniques (Ouchterlony double diffusion, radial immunodiffusion); no available antibody code captures the technique dimension.
276839009 (Implantation of drug delivery reservoir)(not mapped)ICHI has no specific code for implantation of a drug delivery reservoir (e.g., subcutaneous port or implantable drug pump); a site-agnostic reservoir implantation concept has no suitable ICHI counterpart.
1187070009 (Implantation of drug delivery reservoir using fluoroscopic guidance)(not mapped)As with the parent concept, ICHI lacks a code for drug delivery reservoir implantation; the fluoroscopic guidance specification is also not represented in ICHI for this procedure type.
9178008 (Implantation of nerve end into bone)(not mapped)No ICHI code exists for the specific procedure of implanting a nerve end into bone (used for phantom limb pain or stump neuromas); peripheral nerve device insertion and nerve transplantation codes both misrepresent the procedure.
70852009 (Implantation of prosthetic limb device)(not mapped)ICHI has no assignable category code for implantation or fitting of a prosthetic limb device; "Upper limb prostheses" and "Lower limb prostheses" appear only as extension entries without procedure codes.
372037007 (Implementation of latex allergy precautions)(not mapped)ICHI contains no code for latex avoidance, allergen precautions, or clinical environment modification for allergy safety; available infection-control and immunological function codes do not cover this concept.
443385002 (Incision and drainage of hematoma)(not mapped)ICHI contains no generic, body-site-unspecified hematoma drainage code; all ICHI drainage codes are site-specific, and the SNOMED concept's lack of body-site specificity means no single ICHI category code is a reasonable match.
61301009 (Incision and drainage of skin)(not mapped)ICHI organises skin/subcutaneous drainage by anatomical region (head/neck, trunk, upper limb, lower limb) and provides no single body-site-unspecified skin drainage code; the generic NEC integumentary codes are too broad to serve as a meaningful mapping.
61240002 (Incision and exploration of epididymis)(not mapped)ICHI does not classify the epididymis as a distinct target for incision or exploration; the male genital system blocks (NGD spermatic cord, NGL testis, NGG scrotum) contain no dedicated epididymis incision or exploration code.
19218007 (Incision and exploration of gallbladder)(not mapped)The ICHI KCF block (Interventions on gallbladder) contains no FA (incision) or AE (exploration) action code — only biopsy, drainage, calculus extraction, repair, and excision codes, so no reasonable category captures incision-and-exploration of the gallbladder.
33455009 (Incision and exploration of inguinal region)(not mapped)ICHI has no FA (incision) or AE (exploration) action code applied to the inguinal region as an anatomical space — the PAM block (inguinal abdominal wall) covers only hernia repair, and no other ICHI block represents open exploration of the inguinal region.
12838003 (Incision and exploration of neck)(not mapped)ICHI does not have a generic incision-of-neck or exploration-of-neck category — the neck is represented only through specific anatomical sub-targets (artery, vein, cervical spine, cervical lymph node), none encoding the broad, anatomically non-specific concept of incising and exploring the neck as a region.
43642001 (Incision and exploration of retroperitoneum)(not mapped)ICHI has no code targeting the retroperitoneum as a distinct anatomical space for incision or exploration; the retroperitoneum only appears as an extension qualifier (XA6S21), and the nearest structural codes refer to a different compartment.
385950008 (Incision care assessment)(not mapped)ICHI has no specific code for the nursing/post-operative assessment of a surgical incision site; the closest candidates (enterostomy assessment PTB.AA.ZZ, tracheostomy assessment PTC.AA.ZZ) are scoped to specific artificial body structures and are not semantically equivalent to a general incision care assessment.
54408002 (Incision of antecubital fossa)(not mapped)ICHI has no specific code for incision of the antecubital fossa; the LAE block (skin and subcutaneous tissue of upper limb) lacks an FA (incision) action code, and no musculoskeletal or soft tissue incision code specific to this region exists in ICHI.
175010001 (Incision of bulbourethral glands)(not mapped)ICHI contains no code for the bulbourethral (Cowper's) glands; the male genital system section covers prostate, seminal vesicle, spermatic cord, scrotum, testis, and penis but not the bulbourethral glands, and no residual male-genital incision NEC category with an FA action code exists in the classification.
36019003 (Incision of carotid body)(not mapped)The carotid body appears only as an extension/target code (XA0F61) in ICHI with no assignable intervention codes in that target — ICHI interventions on the carotid region cover the carotid artery (IBB), not the carotid body (a chemoreceptor organ). No ICHI code represents incision of the carotid body.
81259007 (Incision of cerebral meninges)(not mapped)The cerebral meninges block (BlockL5-AAC) contains codes for biopsy, drainage, excision, repair, and release of cortical adhesions, but no incision (FA action) code exists for this target. No ICHI code represents incision of the cerebral meninges.
9993006 (Incision of diaphragm)(not mapped)The ICHI block for diaphragm interventions (MCX) contains only biopsy, imaging, device insertion, and repair codes — no incision (FA) code exists for the diaphragm.
1176009 (Incision of inguinal region)(not mapped)ICHI does not have a code for generic incision of the inguinal region as a body area; all ICHI inguinal codes relate to inguinal lymph node interventions or inguinal hernia repair, none of which equate to a non-specific incision of the inguinal region.
179721005 (Incision of joint ligament)(not mapped)ICHI only has site-specific ligament incision codes (hand/finger, lower leg, foot/toe) and provides no generic or joint-unspecified "incision of ligament" code; the SNOMED concept is body-site-neutral and none of the available site-specific codes can be considered a reasonable generic match without introducing misleading specificity.
53145005 (Incision of lymphatic vessel)(not mapped)The ICHI lymphatic vessel block (BlockL5-DFO) contains drainage, occlusion, repair, and anastomosis codes but has no incision (FA action) code for lymphatic vessel. No sufficiently close alternative exists across the classification.
49801005 (Incision of perirectal tissue)(not mapped)No ICHI code exists for incision of perirectal tissue; the KBW (rectum) block has no incision action code, and the nearest candidates differ in either action or anatomical target sufficiently that no reasonable mapping can be assigned.
78488009 (Incision of pleura)(not mapped)ICHI has no incision (FA action) code for the pleura target (JCA block); the pleura block contains biopsy, excision, drainage, and pleurodesis codes but no incision code. JCH.FA.AA (thoracotomy NEC) is an incision of the thoracic cavity rather than specifically of the pleura, and is therefore too semantically distant for a valid mapping.
58333007 (Incision of temporal pouches)(not mapped)ICHI contains no assignable code for incision of the temporal pouch (infratemporal or deep temporal fascial space); the soft tissue head/neck block (MAS) only covers imaging and rehabilitation interventions, and no incision/drainage code exists for this anatomical space.
1296609000 (Incision of urachal cyst)(not mapped)ICHI has no dedicated codes for the urachus or urachal anomalies; the urachus is not represented as a target structure in any assignable intervention category. No sufficiently close proxy exists without misrepresenting the anatomical target.
1296611009 (Incision of urachal sinus)(not mapped)As with urachal cyst, the urachus is absent from ICHI's target axis and no assignable code covers intervention on a urachal sinus; using the bladder or urinary system codes would represent a different anatomical structure entirely.
70871006 (Incisional biopsy)(not mapped)ICHI requires a specific anatomical target (the first 3-character axis) for every assignable code, so a generic site-independent procedure category like "incisional biopsy" cannot be represented by a single ICHI category code; no block-level code adequately captures this abstract procedure type.
406868004 (Indigo carmine stain method)(not mapped)Indigo carmine staining is a chromoendoscopy technique used to enhance mucosal contrast during endoscopy; ICHI does not represent specific dye staining methods, chromoendoscopy techniques, or laboratory staining procedures as distinct codeable interventions.
127797006 (Indirect tissue immunofluorescence procedure)(not mapped)Indirect immunofluorescence on tissue is a laboratory diagnostic technique using fluorescently-labelled antibodies to detect antigens in tissue sections; ICHI does not include specific laboratory immunological staining or immunofluorescence methods as assignable codes.
416217004 (Indocyanine green staining of lens capsule)(not mapped)ICHI has no code for dye-staining or chromatic marking of ocular structures; the lens block contains only mechanical and implant interventions, and no staining/colouring/capsule-marking procedures exist anywhere in the classification.
406869007 (Indophenol from naphthol stain method)(not mapped)This SNOMED concept describes a histochemical laboratory staining technique; ICHI does not classify specific histological stain methods or laboratory analytical procedures of this kind.
8290005 (Induced cardioplegia)(not mapped)ICHI does not contain a dedicated code for cardioplegia (pharmacological or solution-based cardiac arrest used during cardiac surgery); the closest heart-related codes (HZZ.DB.AE injection into heart, PSA.DD.AF cardiopulmonary bypass) do not capture the specific concept of deliberately inducing cardiac standstill for myocardial protection.
700041001 (Induced termination of pregnancy under unsafe conditions)(not mapped)ICHI has specific termination-of-pregnancy codes by technique, but none encode the safety condition of the procedure — "unsafe conditions" is a contextual qualifier, not a distinct intervention. Assigning any specific technique code would misrepresent the SNOMED concept which is defined by its unsafe setting.
24899008 (Infection control culture overnight)(not mapped)This SNOMED concept denotes a specific laboratory procedure — an overnight microbiological culture performed for infection control surveillance purposes. ICHI does not contain specimen culture or microbiological laboratory procedure codes.
231287002 (Infiltration)(not mapped)ICHI does not have a generic, site-unspecified code for infiltration anaesthesia; all anaesthetic injection codes are tied to specific anatomical targets, and no NEC/unspecified infiltration anaesthesia code exists to capture this body-site-agnostic SNOMED concept.
169422001 (Inflammatory infrared therapy)(not mapped)ICHI contains no code for infrared therapy or any specific non-ionising light-based physical modality beyond phototherapy (UV light); the closest candidates refer to ultraviolet/light-based phototherapy and do not cover infrared radiation as a therapeutic modality.
304561000 (Informing health care professional)(not mapped)ICHI does not contain a code for clinician-to-clinician information transfer or notifying a health care professional; this concept sits outside ICHI's scope of health interventions applied to or on behalf of a patient.
700502006 (Informing patient of outcome of child and adolescent mental health service choice appointment)(not mapped)ICHI has no code representing the act of informing/notifying a patient of an appointment outcome or service choice decision; the closest ICHI concepts (education, advising, counselling) are about clinical content domains rather than communicating administrative or service-level outcomes.
310868002 (Informing patient of prognosis)(not mapped)ICHI does not model the act of communicating a prognosis to a patient as a distinct coded intervention; the "advising" and "counselling" action codes in ICHI are attached to body-function or activity targets, not to the act of delivering prognostic information as such.
313007005 (Informing relative of diagnosis)(not mapped)ICHI has no code for the act of disclosing a diagnosis to a family member or relative; while the system includes support interventions targeting family (UCB, UCC blocks) and interpersonal interaction codes, none captures the specific clinical act of communicating diagnostic information to a third-party relative.
313008000 (Informing relative of prognosis)(not mapped)For the same reasons as informing relative of diagnosis, ICHI contains no code representing the clinical act of communicating prognostic information specifically to a relative.
387760006 (Infusion care)(not mapped)ICHI does not have a code representing the holistic nursing/clinical activity of "infusion care" (preparation, administration, monitoring, and management of infusions); the closest candidates such as pharmacotherapy administration codes capture only one aspect and do not reflect the broader care concept.
243132000 (Inhaled drug administration)(not mapped)ICHI has no code for inhaled/inhalational drug administration as a general route concept; the closest codes are route-specific (e.g., inhalational anaesthesia PZA.DC.AC or oral administration for respiratory system) but none capture the generic act of administering any drug via the inhaled route.
47356008 (Inhibition test)(not mapped)ICHI contains no code for an inhibition test (a generic functional or microbial inhibition assay); the closest analogue, antimicrobial susceptibility testing, is too specific, and no general inhibition test category exists in the classification.
182643001 (Inject organ for local action)(not mapped)ICHI's injection codes are all organ-specific (e.g., injection into heart, spinal canal, peripheral nerve) and there is no generic "inject organ for local action" category that captures the SNOMED concept as an abstract procedure type; the SNOMED concept is a general class rather than a specific procedure, so no single ICHI code provides a reasonable match.
385791001 (Injection administration management)(not mapped)"Injection administration management" is a clinical management/coordination concept — overseeing or planning injection therapy — which has no ICHI equivalent. ICHI codes represent specific physical interventions performed on body targets; administrative or management-level activities of this type are not represented in the classification.
1295194008 (Injection into lymphatic tissue)(not mapped)No ICHI code exists for injection into lymphatic tissue. The lymphatic system block (BlockL4-DFA and its children) covers biopsy, drainage, imaging, and excision of lymph nodes, but injection into lymphatic tissue is absent from the classification entirely.
230855001 (Injection into subcutaneous reservoir connecting to brain lesion)(not mapped)This concept describes injection via an implanted subcutaneous device (such as an Ommaya reservoir) that provides access to a brain lesion; ICHI has no code for injection through an intracranial reservoir or device, and no brain injection code of any kind — the closest codes (AAA.DL.AE percutaneous insertion of device into brain, AAA.JB.AA drainage of brain) do not capture this action.
68856007 (Injection of brain)(not mapped)No ICHI assignable code exists for injection into the brain — the brain interventions block (AAA) contains no DB-action (injection) category code, and no other ICHI code adequately represents this procedure.
118151002 (Injection of gastrointestinal tract)(not mapped)ICHI has no single assignable category code for injection into the gastrointestinal tract as a whole; GI injection codes are split by specific sub-site (oesophagus, stomach, duodenum, colon, anus) and none of these sub-site codes would accurately represent the broad, non-site-specific SNOMED concept without inappropriate narrowing.
78426005 (Injection of mouth)(not mapped)ICHI has no assignable injection code for the mouth or oral cavity; the oral cavity NEC codes cover incision, excision, repair, and drainage but not injection, and no broader mouth injection category exists.
112856002 (Injection of pharynx)(not mapped)ICHI has no code for injection into the pharynx generically — the pharynx-related codes under KAR (oral pharynx) and JAM (nasopharynx) do not include an injection/substance-delivery action, and the DB (injection) action codes in ICHI do not extend to any pharynx target.
430046001 (Injection of radioactive isotope)(not mapped)ICHI has no generic code for administering a radioactive isotope by injection; the closest related codes are organ-specific (e.g., EBA.GA.BE for radioactive iodine ablation of thyroid) or imaging-specific (radioisotope scan codes), none of which adequately represent a general radioactive isotope injection without introducing unacceptable clinical distortion.
431865004 (Injection using fluoroscopic guidance)(not mapped)This SNOMED concept is a procedural qualifier describing the guidance modality rather than a discrete intervention; ICHI represents image guidance as an extension code (XG0MQ2 "With image guidance") appended to a substantive procedure code rather than as a standalone assignable code, so no independent ICHI mapping is possible.
711107008 (Injury care)(not mapped)ICHI contains no generic injury care or wound management category corresponding to this broad SNOMED concept; available management codes in ICHI are device- or organ-specific rather than injury-generic.
1296972008 (Inotropic therapy)(not mapped)ICHI has no code representing inotropic agent administration; existing administration-of-medication codes are scoped to pain, immunology, or nutrition, and no cardiac/vasoactive drug-delivery category exists.
736774000 (Inpatient surgery care)(not mapped)ICHI encodes specific surgical procedures individually and has no overarching code for inpatient surgical care as an administrative or care-pathway concept; UEP.RG.ZZ would lose surgical specificity and is too generic to map.
309719006 (Insertion of Gentamicin beads into bone)(not mapped)ICHI contains site-specific codes for implantation of devices into named bones (e.g., tibia, facial bone) and injection into bone marrow, but has no generic "bone NEC" implantation code that captures the placement of antibiotic-impregnated beads into unspecified bone; no existing ICHI category adequately represents this concept without introducing significant site specificity not present in the SNOMED concept.
238313000 (Insertion of hormone implant into pelvic fascia)(not mapped)ICHI contains no code for device or substance implantation into pelvic fascia or pelvic connective tissue; the pelvic intervention blocks focus on vascular structures, and no fascia-specific implantation category exists anywhere in the classification for this anatomical target.
426475004 (Insertion of iris retractors)(not mapped)The ICHI iris block contains no code for insertion of a device or retractor into the iris; the available codes cover biopsy, excision, drainage, destruction, and repair, none of which capture the concept of placing mechanical iris retractors to dilate the pupil intraoperatively. No reasonable ICHI match exists.
53999001 (Insertion of pack)(not mapped)ICHI contains only site-specific packing codes (nasal, rectal, auditory canal, uterus, vagina, cervical canal) with no generic or site-unspecified "insertion of pack" code.
440093006 (Insertion of radioactive implant into interstitial tissue using ultrasound guidance)(not mapped)No ICHI code exists for interstitial brachytherapy (insertion of radioactive implant/seeds into soft tissue) as a general procedure; the only closely related code is site-specific (prostate).
40670003 (Insertion of radioactive isotope)(not mapped)ICHI does not contain a general-purpose code for insertion of a radioactive isotope independent of target body site or route; radiotherapy-related codes are either site-specific or listed only as extension/qualifier concepts.
1296925008 (Insertion of stent)(not mapped)ICHI has no single generic "insertion of stent" code; stent insertion codes are always bound to a specific anatomical target.
432586006 (Insertion of stent using ultrasound guidance)(not mapped)ICHI does not have a code for stent insertion defined primarily by its guidance modality (ultrasound); guidance is a means axis value applicable across many body-site-specific codes, and no single cross-site "ultrasound-guided stent insertion" code exists.
1263464003 (Insertion of tube)(not mapped)"Insertion of tube" is an extremely generic SNOMED concept that does not resolve to a specific body site; ICHI has no comparably generic tube-insertion category — every ICHI tube/drain insertion code is tied to a specific anatomical target.
431398002 (Insertion using fluoroscopic guidance)(not mapped)ICHI classifies interventions by anatomical target, action, and means, and does not have a cross-cutting code for a procedural modifier such as "fluoroscopic guidance" in isolation; fluoroscopy is captured within specific procedure codes via the means axis.
406870008 (Insoluble berlin blue stain method)(not mapped)ICHI does not include laboratory staining techniques or histochemical methods such as the Prussian blue (Berlin blue) iron stain. This is a laboratory/pathology procedure at a level of granularity not represented in ICHI's classification.
225254003 (Inspecting cervical cap)(not mapped)ICHI does not contain a code for inspecting or checking a cervical cap (a barrier contraceptive device); there is no ICHI category covering the examination or fitting-check of this specific device.
53384006 (Instrumental dilation and stretching)(not mapped)ICHI does not contain a generic, site-unspecified "instrumental dilation and stretching" code; all ICHI dilatation codes are tied to a specific anatomical target (e.g., cervical canal, urethra, cardiac valves), and no residual/NEC category covering dilation as a non-site-specific procedure exists.
103722000 (Instrumental elevation)(not mapped)"Instrumental elevation" is a generic surgical technique (lifting/elevating tissue with an instrument) that cuts across many body sites and procedure types. ICHI has no generic elevation code; the sole elevation code found (MAA.LC.AA — Elevation of skull fracture fragments) is site-specific to skull fractures, making it an inappropriate mapping for this body-system-agnostic SNOMED concept.
65206009 (Interdisciplinary medical team conference)(not mapped)ICHI contains no code for a formal multidisciplinary or interdisciplinary team conference; the closest available codes (case coordination PZB.TD.ZZ, individualised planning PZB.TB.ZZ) describe care management activities rather than a structured meeting of multiple clinical disciplines, and none captures the concept adequately.
32350008 (Intermediate delay of small flap at scalp)(not mapped)ICHI has no code for a "delay" procedure (the staged devascularisation step performed prior to definitive flap transfer); the only scalp-specific codes in the integumentary block cover repair, grafting, reattachment, and excision but not flap delay, and the tissue-flap extension codes describe flap type rather than this preparatory staging step.
229567009 (Intermittent compression therapy)(not mapped)ICHI has no code representing intermittent pneumatic or mechanical compression therapy as a standalone intervention; the closest candidate (anti-oedema stockings) is a device/product entry without an assignable procedure code, and compression therapy does not fit any of the musculoskeletal massage, immobilisation, or dressing codes without significant distortion of the concept.
306908002 (Intermittent compression therapy to hand)(not mapped)As with the unqualified concept (229567009), ICHI contains no code for intermittent compression therapy, and the further anatomical specification to the hand does not yield a match; MIS.PC.ZZ (Massage of soft tissue of upper limb, NEC) is a different modality and covers the whole upper limb rather than the hand, so no reasonable ICHI mapping exists.
20299006 (Intermittent manual traction)(not mapped)ICHI contains no code representing traction as a standalone intervention; searches across traction, musculoskeletal manipulation, closed reduction, and physiotherapy terminology returned no semantically adequate match for the specific practice of applying intermittent manual pulling force to a body part.
225417009 (Intermittent observation)(not mapped)"Intermittent observation" in clinical practice refers to a nursing surveillance frequency protocol (scheduled periodic patient checks), a concept absent from ICHI; the closest candidate PZB.AM.ZZ (Observation of whole person) belongs to rehabilitation functional assessment and is semantically distinct from periodic clinical safety monitoring.
428952008 (Intermittent subcutaneous infusion of therapeutic substance)(not mapped)No ICHI category code exists for subcutaneous infusion or injection of a therapeutic substance; the integumentary section contains only anaesthetic injections and device insertions into skin/subcutaneous tissue, and no general route-of-administration drug delivery codes were found.
1255818003 (International Dysphagia Diet Standardisation Initiative Framework - Easy to Chew Level 7 food)(not mapped)This SNOMED concept is a diet texture/consistency level descriptor from the IDDSI framework — it classifies a type of food, not a health intervention performed on a patient. No ICHI code exists for assigning or prescribing a specific IDDSI diet level; the closest ICHI codes (UAB.DA.ZZ Food modification, UAB.TI.ZZ Prescription of food, KTC.PM.ZZ Education about swallowing) each represent distinct interventions that do not correspond to this classification concept.
169370006 (Interstitial brachytherapy to pelvis using temporary implant)(not mapped)ICHI has no generic "pelvis by radiotherapy" code; pelvic radiotherapy codes exist only for specific organs (prostate NGA.GA.BA, uterus NME.GA.BA, cervix NMF.GA.BA, bladder NAI.GA.BA, pelvic lymph nodes DFF.GA.BA), none of which captures the SNOMED concept of brachytherapy to the pelvis as an undifferentiated anatomical region.
169368002 (Interstitial brachytherapy to thorax using temporary implant)(not mapped)ICHI has no thorax-level radiotherapy destruction code; destruction of lung lesion codes (JBF.GA.AA/AB/AE) lack the radiotherapy means (.BA), and no .GA.BA code exists for lung, pleura, chest wall, or thorax as a region, making no reasonable ICHI match available for thoracic brachytherapy via temporary implant.
14370001000004106 (Intestinal rehabilitation program)(not mapped)ICHI has no code representing a multi-component intestinal (or short-bowel) rehabilitation program; XG4691 "Rehabilitation and Habilitation" is a classification extension code rather than an assignable intervention, and no digestive-specific rehabilitation program code exists in ICHI.
87594008 (Intra-abdominal manipulation of intestine)(not mapped)ICHI splits intestine interventions into small intestine NEC (KBK.LD.AA) and large intestine NEC (KBZ.LD.AA) with no single code covering the intestine as a whole; no individual ICHI category code adequately represents an undifferentiated intra-abdominal manipulation of intestine.
68268007 (Intra-arterial infusion)(not mapped)ICHI does not contain a code for intra-arterial infusion or injection of a substance into an artery as a standalone act; exhaustive searching of the arterial intervention blocks (IZA, ICA, IBA, IEA, IFA) confirmed that ICHI only codes specific arterial procedures (thrombolysis, dilatation, bypass, reconstruction) but has no general drug or fluid infusion into an artery concept.
58717007 (Intra-arterial infusion of prophylactic substance)(not mapped)ICHI contains no code for intra-arterial infusion or injection of a drug/substance generically; the IZA (artery NEC) block covers structural interventions (thrombolysis, endarterectomy, bypass, repair) but has no equivalent for pharmacological infusion via artery.
298712009 (Intra-arterial infusion of saline)(not mapped)ICHI has no code for intra-arterial infusion of saline or any comparable arterial fluid administration; saline infusion via artery is typically a technique component rather than a classified intervention in ICHI, and no arterial injection/infusion category exists anywhere in the ICHI hierarchy.
372246008 (Intracranial procedure)(not mapped)This SNOMED concept is a high-level administrative placeholder for any intracranial procedure and has no meaningful ICHI counterpart — ICHI does not carry such a generic grouper code, and assigning any specific category code would misrepresent the intentionally broad SNOMED concept.
708010003 (Intraosseous access care management)(not mapped)ICHI does not contain a code for managing or maintaining an intraosseous access device; the closest candidates do not represent the ongoing care management of an established intraosseous access site, and no adequate match exists in the classification.
1156383000 (Intravascular brachytherapy)(not mapped)ICHI contains a brachytherapy seeds concept but with no assignable code, and there is no ICHI category for intravascular (endoluminal) radiation therapy to vessels; the classification does not cover this specialized interventional radiology technique.
231246003 (Intravenous regional block)(not mapped)Intravenous regional anaesthesia (Bier block) is a distinct technique — anaesthetic injected intravenously into an isolated, tourniquet-occluded limb — and ICHI contains no code representing this. Available anaesthetic injection codes do not capture the specific mechanism.
278868002 (Intravenous regional sympathetic block)(not mapped)This is a specialised variant of IV regional block (Bier block directed at the sympathetic nervous system, e.g. guanethidine block), and ICHI has no corresponding code; sympathetic nervous system block codes cover direct nerve injection/excision, not IV regional sympatholytic infusion.
74070004 (Introduction of catheter into vertebral artery)(not mapped)ICHI has no dedicated block or assignable code for the vertebral artery as a vascular target; it does not appear in the extracranial head and neck artery block (IBA/IBB) and the intracranial artery block (IAA) does not include a device/catheter insertion code.
235431004 (Intubation of gastrointestinal tract via fistula)(not mapped)ICHI has no code that captures insertion/intubation of the gastrointestinal tract specifically via a fistula route; the fistula-related codes in ICHI concern repair rather than access, and no GI insertion code qualifies the fistula approach.
306814005 (Investigation results education)(not mapped)ICHI organises education codes by the body function or body system being educated about, not by the act of communicating investigation or diagnostic results to a patient. No ICHI code captures the clinician-to-patient communication of test/investigation findings.
52748007 (Involuntary hospital admission)(not mapped)ICHI does not have a code for compulsory or involuntary psychiatric or medical detention/admission; searches across admission, hospitalization, compulsory, coercive, legal services, and civil protection services yielded no applicable ICHI category.
175982003 (Irrigation of kidney)(not mapped)ICHI contains no dedicated code for irrigation of the kidney or renal pelvis; the closest codes (renal pelvis drainage NAB.JB.AA, urinary bladder irrigation NAI.JA.AC) involve different anatomical targets or different actions.
1230042009 (Irrigation of tube)(not mapped)ICHI does not have a generic "irrigation of tube" code; its irrigation codes are organ-specific. The closest structural analogue is KCF.SN.AC (biliary tube irrigation) but that is restricted to biliary tubes.
430615004 (Irrigation of urethra)(not mapped)A thorough search of the urethra interventions block found no code for urethral irrigation or lavage; the urethra codes cover biopsy, resection, dilatation, repair, and drainage but not irrigation.
713123002 (Irrigation of urostomy)(not mapped)ICHI contains no code for irrigation of a urinary stoma (urostomy/ileal conduit); the NAN block covers ileal conduit endoscopy and imaging but not irrigation.
816078002 (Ischemic preconditioning)(not mapped)Ischemic preconditioning is a deliberate transient application of brief ischemia-reperfusion cycles to confer organ protection; no ICHI code captures this concept across preconditioning, remote ischemic preconditioning, or vascular occlusion for protection.
15543008 (Isodose computation for brachytherapy)(not mapped)Isodose computation is a radiation physics planning calculation that determines dose distribution for brachytherapy; ICHI does not include dosimetry or treatment planning calculation steps as distinct interventions.
56636003 (Isodose computation for external beam radiation therapy)(not mapped)Like its brachytherapy counterpart, isodose computation for EBRT is a dosimetric planning calculation, not a clinical intervention classifiable in ICHI.
169125005 (Isotope B12 with iron absorption)(not mapped)ICHI contains no code for a radiolabelled vitamin B12 or iron absorption study (Schilling test or similar); searches for absorption, Schilling, B12, isotope, and function study returned no relevant match.
406871007 (Janus green B stain method)(not mapped)Janus green B is a vital dye used to stain mitochondria in cytological preparations; ICHI contains no codes for specific histological or cytochemical staining techniques.
406872000 (Jenner-Giemsa stain method)(not mapped)ICHI does not contain codes for specific histological/haematological staining methods such as Jenner-Giemsa; the classification operates at higher granularity and does not represent laboratory staining techniques as distinct codes.
312948004 (Karyotype determination)(not mapped)ICHI's laboratory section (XG) covers only a limited set of essential tests and contains no code for chromosomal analysis or karyotyping.
406873005 (Kenacid blue R stain method)(not mapped)Kenacid blue R is a specific histological protein staining technique; ICHI does not model specific histochemical or dye staining methods as assignable intervention codes.
117641004 (Ketone solvent identification)(not mapped)This is an analytical/forensic chemistry procedure for identifying ketone-based solvents; ICHI contains no assignable codes for solvent identification or analytical chemistry procedures of this specificity.
252935003 (Kibrick gelatin agglutination test)(not mapped)The Kibrick gelatin agglutination test is a specific immunological assay for sperm-agglutinating antibodies in male infertility evaluation; ICHI has no code for sperm antibody testing or immunological fertility assays.
175898006 (Kidney operation)(not mapped)High-level SNOMED grouper for all surgical interventions on the kidney; the closest ICHI counterpart is the organisational block BlockL5-NAA which is not an assignable category code.
54610007 (Kidney panel)(not mapped)A "kidney panel" is a laboratory test battery (creatinine, BUN, electrolytes); ICHI does not contain a dedicated kidney function panel or renal chemistry profile code.
232851001 (Konno aortoventriculoplasty)(not mapped)The Konno procedure is a combined aortic valve replacement with patch enlargement of the LVOT and interventricular septum; no single ICHI code captures this multi-component intervention.
386343008 (Labor suppression)(not mapped)ICHI contains codes for induction and augmentation of labour but no code for suppression/inhibition of labour (tocolysis).
67664000 (Laboratory calculation)(not mapped)"Laboratory calculation" refers to a derived numeric result computed from laboratory measurements (e.g., calculated LDL); ICHI's "calculation functions" block (AUJ) addresses cognitive calculation in rehabilitation, semantically unrelated.
386344002 (Laboratory data interpretation)(not mapped)ICHI does not include a code for the cognitive or analytical act of interpreting laboratory results; the Essential laboratory tests block covers specimen-based tests only.
406874004 (Lacmoid stain method)(not mapped)ICHI contains no code for staining methods or specific histological/cytological techniques; Lacmoid staining is a highly specific laboratory technique without ICHI representation.
117818005 (Lamellar bodies count)(not mapped)A lamellar bodies count is a quantitative laboratory test on amniotic fluid for fetal lung maturity; ICHI contains no code for this procedure or fetal pulmonary maturity assessment.
107818000 (Larynx manipulation)(not mapped)ICHI contains no manipulation action code for the larynx; the manipulation action axis (PA) is applied only to joints and spinal structures, with no JAN code combining the larynx target with a manipulation action.
386345001 (Laser precautions)(not mapped)"Laser precautions" is a nursing/safety protocol (eye protection, draping, fire prevention measures) rather than a clinical intervention on a body target, action, or behaviour — it has no corresponding code anywhere in ICHI.
228561002 (Laura Mitchell technique)(not mapped)The Laura Mitchell technique is a specific physiological relaxation method (contraction-then-release of opposing muscle groups); searches across relaxation, physiotherapy, stress management, and movement therapy returned no matching ICHI category.
117306005 (Lawson-Van Gieson stain method)(not mapped)Lawson-Van Gieson is a specific histochemical staining technique used in laboratory pathology; ICHI does not index individual staining methods, returning only high-level extension codes (XG30Q5 Histopathology, XG69Q0 Microscopy) that are not assignable procedural categories.
43426004 (Hydrocelectomy of canal of Nuck)(not mapped)The canal of Nuck is a female-specific peritoneal diverticulum within the inguinal canal; ICHI has no code for the canal of Nuck, hydrocele excision, or any female inguinal canal intervention that corresponds.
250572009 (Hydrogen ion activity measurement)(not mapped)Hydrogen ion activity (pH) measurement is an analytical chemistry measurement on biological specimens with no corresponding ICHI category; ICHI does not classify individual biochemical analyte measurements at this level.
250573004 (Hydrogen ion concentration measurement)(not mapped)ICHI does not contain a code for pH/hydrogen ion concentration measurement; closest electrolyte/metabolic candidates cover fundamentally different physiological domains and would be a significant semantic stretch.
386326005 (Hyperglycemia management)(not mapped)No ICHI code captures a "management" intervention specifically targeting hyperglycemia; available codes cover assessment of metabolic functions or endocrine counselling but not a composite clinical management concept.
443799000 (Hypertonic cryohemolysis test)(not mapped)The hypertonic cryohemolysis test is a specialised in-vitro haematology diagnostic for hereditary spherocytosis; ICHI does not include this level of haematological diagnostic granularity.
414439002 (Hypothyroidism monitoring first letter)(not mapped)This concept represents an administrative act — sending a first written recall letter for disease monitoring; ICHI contains no codes for administrative patient outreach or correspondence activities.
414441001 (Hypothyroidism monitoring second letter)(not mapped)A second written recall letter sent as part of a hypothyroidism monitoring follow-up programme is a primary care administrative workflow action with no equivalent in ICHI.
414442008 (Hypothyroidism monitoring third letter)(not mapped)A third written recall letter in a hypothyroidism monitoring sequence is an administrative correspondence action for which ICHI has no classification category.
416326003 (Hypothyroidism monitoring verbal invite)(not mapped)A verbal invitation to participate in hypothyroidism monitoring is an administrative recall action specific to primary care workflows that has no equivalent code in ICHI.
252205000 (Hypotonic saline infusion test)(not mapped)The hypotonic saline infusion test is a diagnostic provocative test for ADH secretion; no ICHI code for saline infusion, fluid challenge, or ADH stimulation testing was found.
414586001 (Left ventricular dysfunction monitoring first letter)(not mapped)This is a UK QOF administrative code recording that a first protocol letter was sent as part of a left ventricular dysfunction monitoring programme; it represents a documentation/care-pathway adherence event with no clinical procedure equivalent in ICHI.
414588000 (Left ventricular dysfunction monitoring second letter)(not mapped)A UK QOF administrative code recording the sending of a second protocol letter in a left ventricular dysfunction monitoring programme; it represents a documentation event with no clinical procedure equivalent in ICHI.
414589008 (Left ventricular dysfunction monitoring third letter)(not mapped)A UK QOF administrative data entry item — a structured recording template field rather than a clinical procedure; ICHI contains no equivalent administrative documentation concept.
119675006 (Leg repair)(not mapped)"Leg repair" is an unspecified composite SNOMED concept that could cover any tissue in the lower limb; ICHI organises repair by specific tissue type and anatomical target so no single ICHI code maps to the unqualified concept.
406167007 (Legal deposition)(not mapped)A legal deposition is sworn testimony to a legal body, a forensic activity rather than a health intervention on a patient; ICHI's legal-services interventions (block UEJ) are framed at the public-health/system level and do not correspond to giving individual court testimony.
275693003 (Letter from consultant)(not mapped)ICHI contains no code for clinical correspondence between clinicians; this SNOMED concept describes a health record/communication artefact rather than a health intervention, and no available ICHI concept captures the act of writing a consultant letter.
59500009 (Leukocyte poor blood preparation, nylon filter)(not mapped)ICHI has no code for blood-product processing or leukoreduction by filtration; the only blood-related codes (DIA block) cover collection and transfusion, not laboratory preparation or filtering steps, so this blood-bank manufacturing procedure is outside ICHI's scope.
173523001 (Ligation of submandibular duct)(not mapped)The ICHI salivary gland/duct block (KAM) contains codes for incision, drainage, excision, dilatation, transposition, and repair of salivary ducts, but no ligation action code exists for any salivary duct; no reasonable ICHI equivalent is available.
7556002 (Ligation of ureter)(not mapped)The ICHI block for ureter (NAE) contains no ligation or occlusion code — ligation of kidney (NAA.LA.AA) exists but the ureter itself has no LA axis code, and no other ICHI code reasonably represents ureteral ligation without misrepresenting anatomy or action.
406876002 (Light green SF stain method)(not mapped)ICHI does not include laboratory staining methods or histological techniques; the classification focuses on health interventions (clinical procedures, rehabilitation, and public health actions) rather than laboratory analytical methods.
359835002 (Light scatter measurement)(not mapped)Light scatter measurement is a laboratory optical/analytical technique (used in flow cytometry, nephelometry, etc.) that lies outside the scope of ICHI, which does not classify individual laboratory measurement methods.
241739006 (Limb exsanguination)(not mapped)Limb exsanguination is the deliberate mechanical draining of blood from a limb prior to tourniquet application, a preparatory surgical step that has no representation anywhere in ICHI. Extensive searching across drainage, compression, blood vessel, haemostasis, tourniquet, and limb procedure branches returned no applicable code.
79818003 (Liquefaction of specimen with chemical treatment)(not mapped)ICHI does not cover laboratory specimen preparation or processing steps such as chemical liquefaction; its scope does not extend to pre-analytical laboratory procedures performed on collected specimens.
49316001 (Liquefaction of specimen without chemical treatment)(not mapped)As with chemical liquefaction, ICHI contains no codes for physical or mechanical specimen processing procedures; laboratory specimen handling is outside the classification's scope.
406877006 (Lissamine fast red B stain method)(not mapped)ICHI does not represent laboratory staining techniques or histochemical methods at the level of individual dye reagents; no code for staining procedures exists in the classification.
406878001 (Lissamine fast yellow stain method)(not mapped)As with other lissamine dye staining methods, ICHI contains no codes for specific histochemical staining techniques or dye-based laboratory methods, making any mapping unreasonable.
406880007 (Lissamine rhodamine stain method)(not mapped)ICHI does not cover specific fluorescent or histochemical staining techniques at this level of granularity; lissamine rhodamine (a fluorescent label used in immunofluorescence) has no corresponding ICHI code.
431401004 (Lithotripsy using fluoroscopic guidance)(not mapped)ICHI encodes lithotripsy only as extracorporeal shockwave procedures at specific anatomical sites with no fluoroscopic-guidance means axis value; the SNOMED concept identifies a cross-cutting procedural modifier (fluoroscopic guidance) applied to an unspecified lithotripsy, which cannot be represented by any single ICHI category code.
386761002 (Local anesthesia)(not mapped)ICHI does not have a generic "local anesthesia" category code — the PZA.DC codes cover only general anaesthesia modalities (inhalational, intravenous), and ICHI's anaesthetic injection codes are all tied to specific anatomical targets. The SNOMED concept is a high-level procedural category that does not correspond to any single assignable ICHI code.
86743009 (Local excision)(not mapped)"Local excision" in SNOMED is an extremely high-level, non-site-specific concept that functions as an abstract parent for all body-site-specific local excision procedures; ICHI has no equivalent generic cross-site local excision code.
182655007 (Local heating - infrared irradiation)(not mapped)ICHI contains no codes for infrared irradiation or local heat therapy; the radiation section (UBR) covers public health interventions on radiation exposure, not therapeutic application, and no thermotherapy or infrared treatment category exists in the classification.
440275000 (Lower extremity ulcer care management)(not mapped)ICHI has no dedicated code for ulcer care management as a composite service; individual components (debridement, dressing) capture only single steps and do not represent the multi-component clinical management.
229232008 (Lower limb control work)(not mapped)This is a physiotherapy concept for neuromuscular control/coordination exercises of the lower limb; ICHI has no assignable code combining the lower limb target with a neuromuscular control training action.
48716005 (Lymphocyte storage, liquid nitrogen)(not mapped)ICHI does not contain codes for cryogenic cell storage or preservation; no banking codes for lymphocytes or other immune cells exist in the classification.
36091004 (Lyophilization of culture)(not mapped)Lyophilization (freeze-drying) of a microbiological culture is a laboratory preservation technique outside the scope of ICHI's clinical intervention framework.
38985008 (Lysis of adhesions of bursa)(not mapped)ICHI contains no procedural category for interventions on bursa (only extension/anatomy codes with XA- prefix). No release, lysis, or adhesiolysis code for bursae exists anywhere in the classification.
115957000 (Lysis of adhesions of pleura)(not mapped)The ICHI pleura block (JCA) contains no code for release or lysis of pleural adhesions — available codes cover biopsy, excision, pleurodesis, repair, and drainage, but adhesiolysis of the pleura is absent.
63549006 (Lysis of adhesions of thorax)(not mapped)ICHI contains no code for release of adhesions of the thorax as a whole; the thorax-related adhesion codes cover only specific structures (pericardium, trachea, larynx, peritoneal/abdominal cavity), and none represents the broader thoracic compartment or chest wall adhesiolysis.
14400005 (Lysis of adhesions of vitreous by anterior approach)(not mapped)ICHI contains no code for release or lysis of vitreous adhesions — the vitreous body block (BCD) only includes aspiration, injection, destruction, drainage, limited vitrectomy, and vitrectomy. Approach differentiation is not represented.
71306000 (Lysis of adhesions of vitreous by posterior approach)(not mapped)As with the anterior approach variant, ICHI has no dedicated code for vitreous adhesiolysis by any approach. The vitreous body block lacks a release/adhesiolysis category, and the posterior approach distinction cannot be encoded.
713161004 (Lysis of suture of scleral flap using laser)(not mapped)ICHI contains no code representing laser suture lysis of a scleral flap; the sclera block offers only incision, destruction, repair, and reinforcement codes, none of which captures this highly specific post-trabeculectomy laser procedure directed at a suture rather than the scleral tissue.
121343000 (Lysosomal enzyme screen)(not mapped)ICHI's essential laboratory tests block (XG1) covers only basic clinical tests (full blood count, HIV, hepatitis, etc.) and does not include specialized metabolic or lysosomal enzyme panels; no ICHI code exists for biochemical screening for lysosomal storage disorders.
9759000 (Lysozyme resistance test)(not mapped)ICHI has no code for lysozyme (muramidase) testing or lysozyme-specific resistance assays; the closest candidate (antimicrobial susceptibility testing) is focused on antibiotic MIC/sensitivity rather than enzyme-based bacterial resistance characterisation.
5671007 (Magnet extraction of foreign body from ciliary body)(not mapped)The ciliary body block (BBD) contains only six codes covering biopsy, destruction, excision, bypass, and repair — there is no foreign body removal code for the ciliary body, and no other ICHI code adequately captures magnet extraction from this specific intraocular structure.
275827007 (Maintaining asepsis)(not mapped)ICHI does not contain a code representing the clinical practice of maintaining aseptic technique during a procedure; the infection control codes in ICHI (e.g., UEP.VE.ZZ) are scoped to public health or environmental interventions, not intraoperative aseptic practice, and no close analogue exists at any hierarchy level.
401137000 (Maintaining equipment)(not mapped)ICHI does not represent healthcare equipment maintenance as a classifiable health intervention; the classification covers clinical, rehabilitative, and public health acts performed on or for patients, and administrative or technical equipment servicing falls outside its scope entirely.
372061000 (Maintaining the patient's dignity and privacy)(not mapped)ICHI contains no code representing the preservation of patient dignity and privacy as an intervention; this concept describes a nursing/ethical practice standard rather than a discrete classifiable health intervention, and no analogous code was found across clinical, rehabilitation, or health service blocks.
265153001 (Maintenance of electromagnetic bone stimulator)(not mapped)ICHI contains no assignable category code for maintenance or management of a bone growth stimulator (electromagnetic or otherwise); the entries "Bone growth stimulator invasive/noninvasive" appear only as extension/ancillary entries without assignable ICHI category codes, and no SN (management of internal device) code exists for a bone target.
370771002 (Maintenance of invasive device)(not mapped)ICHI has no single assignable category code representing generic maintenance of an invasive device; while the action axis value SN denotes "Management of internal device," it only functions as a code axis component combined with a specific body target, and no target-independent or generic invasive device maintenance category code exists in ICHI.
737567002 (Major surgery care management)(not mapped)ICHI does not contain codes for perioperative or surgical care management as a distinct intervention category; searches for perioperative, care management, case management, and related terms returned no meaningful results, and the only health-management encounter codes (PZB.ZY.ZY/PZB.ZZ.ZZ) are encounter classification codes rather than procedure codes.
398507009 (Malachite green stain method)(not mapped)ICHI does not classify specific histochemical staining reagents or laboratory staining techniques at this level of granularity. No assignable ICHI code covers dye-based stain methods such as malachite green.
286610002 (Male artificial urinary sphincter procedure)(not mapped)Although ICHI contains an entry titled "Artificial urinary sphincter" (entity 36524301), it exists in the beta linearization without an assigned code (both code columns are empty in the source file), making it non-assignable. No other published ICHI category code captures implantation of an artificial urinary sphincter device.
386349007 (Malignant hyperthermia precautions)(not mapped)Malignant hyperthermia precautions is a perioperative safety management activity (avoiding triggering agents in susceptible patients) with no corresponding ICHI code; ICHI does not model anaesthetic risk mitigation or drug-avoidance precaution planning as distinct interventions.
117218003 (Mallory bleach stain method)(not mapped)The Mallory bleach stain is a specific histological staining technique applied to tissue specimens; ICHI does not classify individual laboratory staining methods or histopathological preparation techniques as codeable interventions, and no suitable category or block exists.
311787008 (Management of choking)(not mapped)ICHI contains no code for acute choking management (e.g., back blows, abdominal thrusts/Heimlich manoeuvre); the available respiratory and airway codes address structural procedures or device insertions and do not map to this emergency first-aid intervention.
1163382003 (Management of human milk fortifier in breastmilk)(not mapped)ICHI contains no code for the clinical management of adding human milk fortifier to expressed breastmilk; the nearest concepts (PZA.DA.AC for intracavity administration of nutritional substance, and the VEH breastfeeding behaviour block) do not capture the highly specific neonatal nutrition practice of fortifying breastmilk with a nutritional supplement before feeding.
21824009 (Manipulation of abdominal tissue)(not mapped)ICHI has no generic "manipulation of tissue" action; manipulation codes in ICHI are restricted to joints and spine (PA action axis) and specific organ manipulation (e.g., intra-abdominal bowel manipulation). No ICHI code covers non-specific abdominal soft tissue manipulation.
55998007 (Manipulation of aorta)(not mapped)ICHI partitions the aorta into anatomical segments (ascending, thoracic descending, abdominal, aortic arch) each with their own exploration codes, but there is no single ICHI category code covering the aorta as a whole; the SNOMED concept is a generic category that cannot be precisely mapped to any one segment-specific ICHI code.
8681005 (Manipulation of artery of extremity)(not mapped)ICHI separates upper-limb arteries (ICA block) and lower-limb arteries (IFA block) with no single code spanning both; the generic "artery of extremity" SNOMED concept encompasses both upper and lower limb arteries, and no ICHI category or single block covers this combined scope, nor does an "exploration of artery NEC" code exist.
49554002 (Manipulation of carotid body)(not mapped)The carotid body (paraganglion) has no dedicated ICHI intervention block; it appears only as an extension anatomy code (XA0F61) and a target axis entry (EBE), with no assignable manipulation or procedure codes covering this structure. No ICHI code reasonably represents manual manipulation of this neuroendocrine receptor.
18138008 (Manipulation of epididymis)(not mapped)ICHI has no dedicated block or assignable category for interventions on the epididymis; the closest male genital structure covered is the spermatic cord (NGD block), and none of its child codes represent manipulation of the epididymis. The only epididymis reference is an extension/anatomy code (XA4D25), not an assignable intervention code.
54148001 (Manipulation of parathyroid gland)(not mapped)The parathyroid gland interventions block (EBB) contains only biopsy, scan, partial excision, complete excision, and transplant codes — no manipulation, mobilisation, or repositioning category exists for the parathyroid gland in ICHI, and no code from adjacent blocks provides a reasonable approximation.
61280006 (Manipulation of skin of lower extremity)(not mapped)ICHI has a dedicated block for interventions on skin and subcutaneous tissue of the lower limb (BlockL5-LAG), but it contains no manipulation (action PA) code for skin — manipulation in ICHI is restricted to joints and spine. No assignable ICHI category captures this procedure.
67494002 (Manipulation of skin of neck)(not mapped)ICHI block BlockL5-LAA covers interventions on skin and subcutaneous tissue of head or neck, but offers no manipulation action code for skin; the PA (manipulation) axis is only populated for musculoskeletal targets such as joints and vertebrae. No suitable assignable ICHI category exists.
19146000 (Manipulation of skin of trunk)(not mapped)ICHI block BlockL5-LAB covers interventions on skin and subcutaneous tissue of the trunk, but provides no manipulation action code; ICHI does not encode manual soft-tissue manipulation of skin as a distinct intervention category. No suitable assignable ICHI category exists.
54648002 (Manipulation of skin of upper extremity)(not mapped)ICHI block BlockL5-LAE covers interventions on skin and subcutaneous tissue of the upper limb, but contains no manipulation (PA) action code for skin — that action axis is used only for joints and spine in ICHI. No suitable assignable ICHI category exists.
4449003 (Manipulation of spinal meninges)(not mapped)ICHI block BlockL5-ABC contains 7 assignable codes for interventions on spinal meninges (biopsy, destruction, drainage, debridement, excision, repair), but none represents manipulation; the PA action code does not appear in this block. No suitable assignable ICHI category exists.
30447001 (Manipulation of thyroid gland)(not mapped)ICHI's manipulation action (PA) is only defined for joints and skeletal structures; the thyroid gland interventions block (BlockL5-EBA) contains no manipulation code, and no other ICHI category captures manual handling of the thyroid gland.
10388006 (Manipulation of tissue of diaphragm)(not mapped)The diaphragm interventions block (BlockL5-MCX) contains only biopsy, imaging, device insertion, and repair codes; ICHI does not define a manipulation action on the diaphragm or its tissue, and the PA action axis is restricted to joints and skeletal targets.
22489006 (Manipulation of tissue of lips)(not mapped)The lip interventions block (BlockL5-KAA) includes excision, repair, reconstruction, and size-change codes but has no manipulation code; ICHI's PA (Manipulation) action axis is not applied to soft tissue organs such as the lip.
19297001 (Manipulation of tongue)(not mapped)The tongue interventions block (BlockL5-KAB) covers biopsy, release, excision, fixation, repair, and reconstruction but does not include a manipulation code; the PA action axis in ICHI is exclusively used for joint and spinal targets, not for organs like the tongue.
52473006 (Manipulation of tonsil)(not mapped)The tonsil interventions block (BlockL5-DAA) includes biopsy, incision, destruction, drainage, excision, and haemorrhage control codes but no manipulation code; ICHI's PA action is not applicable to the tonsil as a soft tissue target.
112912003 (Manipulation of vas deferens)(not mapped)ICHI codes covering the spermatic cord / vas deferens (BlockL5-NGD) include vasotomy, ligation, vasovasostomy, and manual reduction of torsion, but none represents a general "manipulation of vas deferens" concept; no sufficiently close match exists across any ICHI block.
71648000 (Manipulation of vein)(not mapped)ICHI encodes vein interventions at site-specific levels (e.g., pulmonary, head and neck, upper limb) with specific actions such as occlusion, extraction, repositioning, and dilatation, but there is no code or block representing generic "manipulation of vein" across all venous sites.
2802005 (Manual dilation and stretching)(not mapped)ICHI contains many body-part-specific dilatation codes and a foreskin stretching code, but no generic or body-site-agnostic "manual dilation and stretching" procedure exists. The SNOMED concept is a high-level, unspecified technique that does not map cleanly to any single ICHI category.
103721007 (Manual elevation)(not mapped)No ICHI code represents a generic "manual elevation" procedure; the only ICHI elevation code (MAA.LC.AA — Elevation of skull fracture fragments) is highly specific to skull surgery and would be a false match for this broad, unspecified SNOMED concept.
38077002 (Manual expression of sebaceous gland)(not mapped)ICHI contains no code for expression or drainage of a sebaceous gland; sebaceous glands are distributed across all skin regions and ICHI has no procedure code that captures manual secretion expression from a non-specific skin gland at a general body site level.
439496004 (Manual microdissection of tissue specimen)(not mapped)ICHI does not contain any code for microdissection of a tissue specimen; this is a laboratory/pathology technique applied to an already-collected specimen rather than a direct intervention on a body part, and falls outside ICHI's scope of assignable intervention codes.
75369004 (Manual reduction of open fracture of hyoid bone)(not mapped)The ICHI "Interventions on hyoid" block contains only partial excision, hyoid suspension, and an unrelated mastoid X-ray — with no fracture reduction code for the hyoid. No other ICHI category captures open fracture reduction of the hyoid bone.
787140002 (Marginal excision)(not mapped)"Marginal excision" is a surgical oncology term describing excision that passes through the reactive zone around a tumour, and no corresponding ICHI code exists; ICHI codes for excision are organised by anatomical target rather than by margin status.
431823005 (Marking of skin using fluoroscopic guidance)(not mapped)ICHI contains no code for skin marking or localisation procedures under image guidance; skin-section codes cover excision, biopsy, drainage, and repair but not surface marking or tattooing for procedural localisation.
431349006 (Marking of skin using ultrasound guidance)(not mapped)ICHI has no category for skin marking or surface localisation under ultrasound guidance; the integumentary system blocks lack any marking or localisation action code, leaving no suitable match.
406890004 (Martius yellow stain method)(not mapped)Martius yellow is a histological staining technique used to process tissue specimens, which falls outside ICHI's scope — ICHI does not cover laboratory or histopathological staining methods.
225701002 (Massaging of the eye)(not mapped)ICHI's eye intervention blocks do not contain any massage or pressure-application code for the eyeball or ocular structures; the massage action axis is only associated with soft tissue and musculoskeletal targets.
237009004 (McRoberts maneuver)(not mapped)The McRoberts maneuver is a specific obstetric repositioning technique (hyperflexion of the mother's thighs to resolve shoulder dystocia) that acts on the maternal body position; ICHI has no code for obstetric maternal positioning maneuvers, and the closest candidates do not capture this intervention's nature or intent.
441472005 (Measurement of amfetamine in meconium specimen using gas chromatography mass spectrometry)(not mapped)ICHI contains no codes for meconium specimens, amphetamine analyte measurement, or chromatographic/mass spectrometry techniques; this highly specific neonatal toxicology assay has no reasonable ICHI equivalent.
439905003 (Measurement of attenuation of ear protection device)(not mapped)ICHI has no codes for testing or measuring the performance characteristics of hearing protection equipment; the interventions on sound and hearing function cover clinical hearing assessment and public health noise interventions, not device attenuation measurement.
442552000 (Measurement of glycine in cerebrospinal fluid specimen)(not mapped)ICHI contains no codes for analyte-specific biochemical measurements in body fluid specimens; the classification does not enumerate individual amino acid assays in CSF, and the essential laboratory tests block covers only a narrow set of high-priority tests that do not include glycine.
439385008 (Measurement of methotrexate in cerebrospinal fluid)(not mapped)ICHI does not contain codes for specific drug-level measurements in biological fluids — there is no therapeutic drug monitoring category, no methotrexate entry, and no concept for analyte quantification in CSF.
84130004 (Measurement of protein in cerebrospinal fluid specimen)(not mapped)ICHI has no assignable code for quantifying a specific substance (protein) within a CSF specimen; while XA1N55 exists as an extension code for cerebrospinal fluid, no procedure code combines analyte measurement with CSF, placing this outside ICHI's classifiable scope.
430925007 (Measurement of substance)(not mapped)This SNOMED concept is a high-level abstract parent for any laboratory/specimen substance measurement, and ICHI has no equivalent generic "measurement of substance" category; ICHI's measurement codes are all anchored to specific body systems, functions, or anatomical targets.
167844007 (Measurement of vomit pH)(not mapped)No ICHI code exists for measuring the pH of vomit or gastric secretion; the digestive system function blocks contain only assessment and observation codes with no specific pH or chemical measurement of emesis.
169283005 (Medical photography)(not mapped)ICHI contains no code for clinical or general medical photography; the only photography code (BCC.BA.BL, Fundus photography) is restricted to retinal imaging.
410324006 (Medical/dental care)(not mapped)"Medical/dental care" is an extremely broad administrative concept denoting general provision of clinical and dental services; no single ICHI category adequately represents this undifferentiated scope without being misleading.
406891000 (Meldola blue stain method)(not mapped)Meldola blue is a specific vital dye used as a lymphatic tracer in sentinel lymph node mapping; ICHI contains no codes for dye administration as a standalone diagnostic technique or for histochemical staining methods, and no combination of target/action/means in ICHI captures this specific laboratory/intraoperative stain procedure.
14348005 (Membrane stability test)(not mapped)The membrane stability test (osmotic fragility test) is a specific haematology laboratory procedure assessing red blood cell resistance to osmotic lysis; ICHI has no code for erythrocyte osmotic fragility or membrane integrity testing, and no sufficiently close surrogate exists among the haematology or laboratory entries found.
414668005 (Mental health monitoring first letter)(not mapped)A "monitoring letter" is an administrative written communication sent to a patient between clinical contacts; ICHI classifies health interventions (procedures, therapies, assessments) and contains no concept for written correspondence or administrative follow-up letters, making no reasonable match possible.
414670001 (Mental health monitoring second letter)(not mapped)Same reasoning as the "first letter" concept — the "second letter" distinction adds only administrative sequencing, and ICHI has no codes for written follow-up correspondence or administrative patient contacts of this type.
406892007 (Metanil yellow stain method)(not mapped)ICHI does not include specific histochemical or dye staining methods such as metanil yellow; laboratory staining techniques at this level of specificity are outside ICHI's scope, and the extension code XG1640 (Immunohisto-chemistry) is only a qualifier extension, not an assignable procedure code.
406893002 (Methyl blue stain method)(not mapped)ICHI contains no staining technique codes at any level of its hierarchy; the Essential Laboratory Tests block covers broad laboratory interventions (Histopathology XG30Q5, Microscopy XG69Q0) but not individual dye-based staining methods as discrete interventions. Methyl blue stain is a specimen preparation technique too granular and procedurally narrow for any available ICHI category.
406894008 (Methyl orange stain method)(not mapped)No ICHI code exists for any dye staining method; methyl orange is a pH indicator dye occasionally used in laboratory staining that has no corresponding ICHI intervention category, and exhaustive searching of histopathology, cytology, microscopy, and laboratory blocks returned no applicable match.
406895009 (Methyl red stain method)(not mapped)Methyl red is used both as a histological stain and as a microbiological indicator (MR-VP test); ICHI has no code for either application as a standalone technique, and no relevant match was found across the Essential Laboratory Tests block or any clinical intervention hierarchy section.
6782004 (Methylene blue plating test)(not mapped)The methylene blue plating test (used to assess bacterial reducing activity or milk bacteriological quality) has no corresponding ICHI code; candidates such as XG50T0 (Antimicrobial susceptibility testing) and XG79M8 (Culture) represent substantially different procedures and would be a misleading assignment.
406896005 (Methylene blue stain method)(not mapped)Methylene blue staining is a widely used histological and microbiological technique, but ICHI classifies interventions at the level of the overall procedure (e.g., Histopathology XG30Q5, Microscopy XG69Q0) rather than the specific staining reagent or technique employed, leaving no suitable assignable code.
406897001 (Methylene violet stain (Bernthsen) method)(not mapped)ICHI does not include laboratory staining techniques or histological staining methods — these are bench-level laboratory processes (preparation/analysis methods) rather than health interventions as classified by ICHI. No code for any dye staining method was found across text searches for "stain", "histological stain", "tissue stain", "staining", or "microscopy" at the intervention level.
46872001 (Microbiologic media preparation)(not mapped)Microbiologic media preparation (e.g., agar plate preparation, broth preparation) is a laboratory support activity and not a clinical health intervention in ICHI's scope. No ICHI code covers this preparatory laboratory process, and the generic "Preparation" action axis code (SI) is not a complete assignable code applicable here.
412895003 (Microbiology battery test)(not mapped)ICHI's "Essential laboratory tests" block contains only individual named tests (e.g., antimicrobial susceptibility testing, blood counts, specific serology); there is no ICHI code representing a panel or battery of microbiology tests as a grouped/ordered set. The concept of a multi-test battery order has no meaningful ICHI equivalent.
314074007 (Microbiology screening test)(not mapped)ICHI does not contain a general "microbiology screening" category; searches across laboratory test blocks, infectious disease surveillance, and screening behaviour codes returned no usable match. The closest candidates (XG50T0 Antimicrobial susceptibility testing, PZB.VC.ZZ Infectious disease contact tracing) are semantically unrelated to the act of performing a microbiology screen.
609100004 (Microscopic cytologic examination of smear of joint fluid specimen prepared using Papanicolaou technique)(not mapped)ICHI contains no code for cytological examination of joint (synovial) fluid, nor any code combining joint fluid specimen analysis with Papanicolaou technique; the generic cytology extension code is too remote to constitute a meaningful mapping for this highly specific procedure.
390782000 (Midwife unit delivery booking)(not mapped)This is an administrative booking act for a midwife-led unit; ICHI does not represent appointment booking or service-registration processes.
228587002 (Mime technique)(not mapped)The Mime technique is a specialised facial neuromuscular rehabilitation method for facial palsy with no corresponding specific code in ICHI; mirror therapy and generic muscle training are not reasonable matches.
225862000 (Minimal supervision)(not mapped)"Minimal supervision" is a level-of-assistance qualifier rather than a discrete health intervention; ICHI has no code representing supervision intensity.
303083004 (Mobilization of the radioulnar joint)(not mapped)ICHI has no radioulnar-joint block; the forearm section omits a forearm-joint subblock, and elbow/wrist codes do not encompass the radioulnar articulation precisely enough.
108262000 (Molecular biology method)(not mapped)ICHI contains no category representing molecular biology as a general class of laboratory technique; XG1 includes only specific named tests.
405825005 (Molecular genetic test)(not mapped)ICHI has no category for molecular genetic testing as a general procedure class; XG1 includes only specific named nucleic-acid tests.
308536008 (Monitoring call)(not mapped)ICHI has no code for a remote/telephone monitoring call as a distinct intervention; telehealth extension blocks describe modality, not the monitoring contact itself.
370835007 (Monitoring for signs and symptoms of infection)(not mapped)ICHI infection-related codes cover infection-control measures and pathogen-specific tests; there is no code for general clinical monitoring of infection signs and symptoms.
703968003 (Monitoring of fluid output from drain)(not mapped)ICHI contains no code for observing or measuring fluid output from a surgical drain; the classification covers active drainage procedures on specific anatomical sites but lacks any generic post-procedural drain monitoring concept.
710987002 (Monitoring patient location using an exit alarm)(not mapped)ICHI has no concept for location tracking devices or exit alarms used to prevent patient wandering/elopement; the closest environmental/technology blocks cover fitting or managing assistive devices rather than the clinical act of monitoring a patient's location.
79852000 (Morphometric analysis, tumor)(not mapped)ICHI has no codes for morphometric or histomorphometric analysis of tumors — the classification does not include laboratory image analysis or computational morphometry procedures. No related ICHI category exists for quantitative tissue measurement.
75406007 (Morphometry, quantitative)(not mapped)Quantitative morphometry is a laboratory analytical technique with no corresponding ICHI code; searches across synonyms returned no procedural categories applicable to this concept. ICHI does not classify this level of laboratory measurement methodology.
281622003 (Mount dental study model)(not mapped)Mounting a dental study model on an articulator is a prosthodontic/orthodontic laboratory procedure not represented anywhere in ICHI; the dental section covers clinical interventions on teeth but has no code for study model fabrication or articulator mounting.
34146008 (Mouse toxin neutralization test)(not mapped)ICHI contains no laboratory/bioassay codes for toxin neutralization tests; the classification does not include in-vitro or animal-model assays such as a mouse neutralization bioassay. No related code exists even at a broader level.
59611000087105 (Mouth rinsing)(not mapped)No ICHI code exists for mouth rinsing or oral cavity irrigation; the closest candidates are either too anatomically specific (KAG.JA.AC — Irrigation of gingiva) or belong to public health behaviour domains rather than a clinical rinsing procedure.
432312003 (MRI guided aspiration)(not mapped)ICHI contains only body-site-specific aspiration codes and has no generic or site-unspecified aspiration category that would represent MRI-guided aspiration as a procedure type in its own right.
277592004 (MRI guided biopsy)(not mapped)ICHI encodes biopsy only in the context of a specific anatomical target; there is no unspecified-site or modality-defined biopsy category. The SNOMED concept — a generic biopsy procedure defined by MRI guidance — cannot be meaningfully mapped to any single ICHI code.
774015005 (MRI guided high intensity focused ultrasound ablation of hemangioma)(not mapped)ICHI contains no codes for high intensity focused ultrasound (HIFU) as a means of ablation, and has no target codes specific to hemangioma as a lesion entity. Neither the technique nor the specific target tissue is represented in ICHI.
774064002 (MRI guided high intensity focused ultrasound ablation of lesion of bone)(not mapped)ICHI's musculoskeletal bone blocks include excision and debridement of bone lesions but no destruction or ablation action for bone at any site (only facial bone has a destruction code), and no HIFU means is represented.
774011001 (MRI guided high intensity focused ultrasound ablation of lesion of spleen)(not mapped)ICHI contains no destruction or ablation code for the spleen — only excision, drainage, repair, and transplantation codes exist under the spleen block — and HIFU ablation is semantically distinct from surgical excision.
431411006 (MRI guided skin marking)(not mapped)ICHI contains no code for procedural skin marking or localisation marking under any imaging guidance; the concept of placing a skin mark under MRI guidance (typically for pre-procedural localisation) has no counterpart in the ICHI classification.
1259974004 (Mucous fistula refeeding)(not mapped)Mucous fistula refeeding is a highly specific neonatal/paediatric procedure in which intestinal contents are transferred from the proximal stoma into the distal mucous fistula to stimulate bowel adaptation; no ICHI code captures this concept — the nearest codes (enterostomy management, intestinal anastomosis, nutritional administration) each represent fundamentally different procedures.
702780005 (Multisystemic therapy)(not mapped)Multisystemic Therapy (MST) is a specific branded, manualised family- and community-based intervention for adolescents with serious behavioural problems; ICHI has no code for this named model. The closest ICHI concepts (psychotherapy for social behaviours or family relationships) capture only individual components of MST and would misrepresent its multi-domain, systemic nature.
408872006 (Musculoskeletal care management)(not mapped)ICHI has no assignable code for generic musculoskeletal care management as a clinical management activity; the "management" codes in ICHI are restricted to device management (e.g., pacemaker management), and no functional equivalent for holistic musculoskeletal care coordination exists in the classification.
10760003 (Musculoskeletal injury rehabilitation)(not mapped)ICHI has no standalone assignable category code for musculoskeletal injury rehabilitation as a procedure; XG4691 ("Rehabilitation and Habilitation") is only an extension code used to qualify other interventions, not an independently assignable procedure code, and no musculoskeletal-specific rehabilitation category exists in the classification.
104245000 (Mycobacterial subtyping)(not mapped)ICHI contains no codes for microbial subtyping, strain typing, or microbiological characterisation procedures; the closest hit (XG50T0 Antimicrobial susceptibility testing) is a different type of microbiological test. Mycobacterial subtyping is a highly specialised laboratory procedure not represented in ICHI's current scope.
275716001 (Mycology)(not mapped)ICHI has no code for mycology as a diagnostic discipline or fungal testing category; searches for mycology, fungal, yeast, and mould all returned no results, and the fuzzy match only surfaced unrelated terms such as cytology. This reflects ICHI's limited granularity for laboratory speciality disciplines.
26787006 (N MYC gene amplification)(not mapped)ICHI does not contain codes for specific molecular/genetic testing such as MYCN (N-MYC) gene amplification by FISH or PCR; the genomic interventions block (BlockL4-PYA) contains only genetic counselling (PYA.PP.ZZ), and the essential laboratory tests section has no oncogene-specific assay codes.
252209006 (Naloxone test)(not mapped)The naloxone test is a neuroendocrine stimulation/challenge test used to assess hypothalamic-pituitary axis function (GH and LH responses), a highly specific pharmacological provocation procedure. ICHI contains no code for opioid antagonist stimulation tests, neuroendocrine challenge tests, or pituitary function provocation tests.
406898006 (Naphthalene black 12B stain method)(not mapped)Naphthalene black 12B (amido black) is a specific histological protein staining technique used in laboratory tissue examination. ICHI does not cover laboratory staining methods or histochemical techniques at any level of specificity — there is no stain, histochemistry, or special stain category in the ICHI intervention classification.
406899003 (Naphthol green B stain method)(not mapped)Naphthol green B is a specific histological staining technique for nucleic acids and proteins in tissue sections. As with other histological stain methods, ICHI contains no codes representing laboratory staining procedures or histochemical techniques, making any mapping impossible.
406900008 (Naphthol yellow S stain method)(not mapped)Naphthol yellow S is a specific histochemical staining technique used in laboratory/pathology settings to demonstrate proteins in tissue sections. ICHI does not encode specific staining methods or histochemistry techniques at this level of granularity, making a meaningful mapping impossible.
408976005 (Neurovascular care management)(not mapped)ICHI contains no code for neurovascular care management as a clinical intervention concept; neither the neurological nor vascular sections of ICHI include a "management" category that corresponds to this nursing/clinical monitoring procedure, and no sufficiently related code could be identified across multiple search strategies.
406901007 (Neutrophil alkaline phosphatase stain method)(not mapped)ICHI does not classify specific histochemical or cytochemical staining techniques; XG1EQ9 (Alkaline phosphatase) is an extension analyte code rather than a procedural method code, and no ICHI category encodes the neutrophil alkaline phosphatase staining procedure as a distinct intervention.
406902000 (New fuchsin stain method)(not mapped)ICHI does not classify specific histological or microbiological staining techniques such as new fuchsin stain; exhaustive searches across staining, microscopy, laboratory, and cytochemistry terms yielded no relevant procedural code, confirming this level of laboratory method specificity is outside ICHI's scope.
406903005 (Nile blue stain method)(not mapped)ICHI contains no codes for specific histological or cytological staining techniques; it does not classify laboratory staining methods at this level of granularity, and no synonym search (stain, dye, histology, cytology, microscopy, laboratory) returned any relevant match.
406904004 (Nitrazine yellow stain method)(not mapped)Like Nile blue stain, ICHI does not include specific laboratory staining methods; no search for nitrazine, dye, stain, or histology yielded a relevant ICHI code, as this level of diagnostic technique granularity is outside ICHI's scope.
270926000 (Non-rhesus red cell antibodies)(not mapped)This concept refers to immunohaematology laboratory testing (detection/identification of non-RhD red cell alloantibodies); ICHI's blood intervention block contains only specimen collection, transfusion, apheresis, and blood product collection — no antibody screening or compatibility testing codes exist in ICHI.
274312009 (Non-surgical biopsy)(not mapped)ICHI biopsies are all coded with a specific body-site target (e.g., DGA.AD.AE for bone marrow, AAA.AD.AE for brain) and there is no body-site-agnostic "percutaneous biopsy, unspecified site" category that could represent this abstract SNOMED grouping concept.
117229004 (Nonspecific esterase stain method)(not mapped)ICHI does not classify laboratory staining or histochemical methods; it focuses on health interventions (clinical procedures, rehabilitation, public health actions), and there is no code in the classification for enzyme histochemistry or staining techniques.
16099009 (Northern blot assay)(not mapped)Northern blot is a specialized molecular biology laboratory technique for detecting and quantifying RNA that has no corresponding code in ICHI; ICHI's laboratory test codes are limited to a small set of WHO essential tests and do not cover molecular biology or gene expression methodologies.
412688005 (Norwalk virus antigen test)(not mapped)ICHI contains specific pathogen antigen codes (e.g., XG1ER6 Dengue virus antigen, XG0XA2 Influenza A and B antigen detection) but has no code for Norwalk virus (norovirus) antigen specifically, nor a generic enteric virus antigen category. No reasonable ICHI equivalent exists.
119709008 (Nose injection)(not mapped)ICHI does not contain a code for injection into the nose (the pattern JAA.DB.AE does not exist), and no adjacent code — such as injection into skin/subcutaneous tissue of head or neck or injection into larynx — is anatomically equivalent to a nasal injection. No reasonable ICHI match exists.
170527001 (Notification of acute encephalitis)(not mapped)ICHI does not model the administrative act of mandatory disease notification (reporting a notifiable condition to public health authorities); the classification contains no "notification," "reporting," or "notifiable disease" concepts at any level of specificity, whether for encephalitis or any other condition.
170528006 (Notification of acute meningitis)(not mapped)As with acute encephalitis notification, ICHI has no classification concept for mandatory reporting of a notifiable disease to public health authorities, and no code exists that approximates the specific administrative act of notifying a case of acute meningitis.
170529003 (Notification of acute polio)(not mapped)ICHI does not include mandatory disease notification as a classifiable intervention; this SNOMED concept represents a statutory administrative reporting act for which there is no corresponding category or even approximate code in the ICHI classification.
406905003 (Nuclear fast red stain method)(not mapped)ICHI does not contain any codes for histochemical staining methods; it classifies health interventions at a procedural level (e.g., biopsy, histopathology) rather than laboratory staining techniques. No reasonable ICHI match exists for this specific reagent-based stain method.
104166004 (Nucleic acid molecular isolation or extraction method)(not mapped)ICHI does not represent laboratory sample preparation methods such as nucleic acid isolation or extraction as standalone interventions; ICHI covers the downstream tests (e.g., XG4U02 Viral nucleic acid amplification test) but not the pre-analytical extraction step itself. No reasonable ICHI code covers this methodological category.
57520004 (Nursing service audit)(not mapped)ICHI has no concept for clinical or service-level audit, quality review, or performance evaluation of a nursing service. The classification covers interventions delivered to individuals or populations, not organisational quality assurance activities of this kind.
185744005 (Obesity monitoring first letter)(not mapped)This concept describes an administrative patient-recall action — sending a first written letter inviting a patient to attend obesity monitoring — a workflow activity with no corresponding category in ICHI's classification of health interventions.
185745006 (Obesity monitoring second letter)(not mapped)Like the first-letter concept, this represents a sequential administrative patient-contact action (a follow-up written letter) that falls entirely outside the scope of ICHI, which does not encode administrative recall or correspondence workflows.
185748008 (Obesity monitoring telephone invite)(not mapped)A telephone-based administrative invitation to attend obesity monitoring is a patient-contact/recall workflow action; ICHI has no codes for administrative telephone outreach or patient-recall communications.
185746007 (Obesity monitoring third letter)(not mapped)This SNOMED concept represents a UK primary care administrative act — sending a third reminder letter — which has no equivalent in ICHI. ICHI does not classify administrative communication or patient recall correspondence.
185747003 (Obesity monitoring verbal invite)(not mapped)This concept represents a verbal (telephone or in-person) invitation to a patient for obesity monitoring follow-up, an administrative workflow action. ICHI contains no codes for patient recall, verbal invitation, or appointment outreach activities.
34077008 (Obliteration of bone cavity)(not mapped)ICHI's six obliteration codes cover only specific anatomical sites (mastoid, tympanomastoid, frontal sinus, calyceal diverticulum, vaginal vault) and none address a generic bone cavity. No sufficiently related bone-obliteration or bone-cavity-filling code exists in ICHI.
120070005 (Obstetrics closure)(not mapped)"Obstetrics closure" is a broad category concept encompassing various closure/repair procedures in obstetric contexts (episiotomy repair, perineal closure, uterine closure post-caesarean) — no single ICHI code represents this grouping, and assigning any specific repair code would misrepresent the concept's scope.
745203002 (Obtaining consent for disposal of human tissue)(not mapped)ICHI does not contain a code for obtaining or documenting consent; it classifies clinical health interventions, not administrative or legal process activities such as consent documentation for tissue disposal. No sufficiently close ICHI category was found.
228653003 (Occupational therapy home visit)(not mapped)ICHI does not encode the service delivery setting (home visit) as part of a code, and while occupational therapy activities exist dispersed across multiple ICHI blocks (self-care, domestic life, activities/participation), no single ICHI code captures the concept of an occupational therapy home visit as a distinct intervention type.
225864004 (One to one care)(not mapped)"One to one care" is a nursing/care intensity descriptor (continuous dedicated individual observation by a single carer), not a discrete health intervention procedure; no ICHI code represents this care delivery model.
440180004 (One to one communication with the client)(not mapped)ICHI does not have a concept representing a one-to-one clinician–client communication interaction as a discrete intervention type; no ICHI code captures the dyadic, clinician-delivered communication encounter described by this SNOMED concept.
225311006 (One to one supervision)(not mapped)ICHI classifies interventions by target body system, function, or activity domain — it does not have a concept for supervision as a care delivery mode or staffing arrangement.
395101001 (Ongoing review)(not mapped)"Ongoing review" is a generic administrative or care-coordination process, not a specific health intervention classifiable by ICHI's Target-Action-Means structure; no ICHI code for periodic or longitudinal review of a patient's status was found.
119283008 (Open biopsy)(not mapped)ICHI organises biopsies by specific body target and has no generic, body-site-agnostic "open biopsy" category; this SNOMED concept is a high-level procedural category that cannot be meaningfully collapsed into any single ICHI code.
240293001 (Open fetal operation)(not mapped)ICHI's fetal intervention block (BlockL5-NMR) contains specific coded procedures (injection, biopsy, version, repair) but no category represents a generic unspecified open fetal operation; the SNOMED concept is intentionally non-specific and cannot be mapped to any single ICHI assignable code without losing meaning.
2598006 (Open heart surgery)(not mapped)"Open heart surgery" is a high-level, unspecified SNOMED category encompassing a wide family of cardiac procedures performed via sternotomy/thoracotomy; ICHI has no single code or even a direct block representing this generic concept, as all ICHI heart codes are specific to a defined action on a defined cardiac structure. No reasonable single ICHI code maps to this broad, non-specific term.
425603008 (Open operation on both pulmonary arteries)(not mapped)The SNOMED concept is a high-level category for any open procedure involving both pulmonary arteries simultaneously, and no single assignable ICHI category code represents this grouping; individual ICHI codes within BlockL5-HID target specific actions (e.g., banding, reconstruction, occlusion) on the pulmonary artery without capturing the bilateral and non-specific nature of this concept.
236268009 (Open operation on male urethra)(not mapped)The SNOMED concept is a non-specific category encompassing any open surgical procedure on the male urethra, and ICHI does not distinguish male from female urethra nor provide a single assignable code for the category as a whole; individual codes within BlockL5-NAM are each specific to a particular action (incision, repair, reconstruction, etc.) and none can validly represent the full breadth of this concept.
265033003 (Operation on pharyngeal pouch)(not mapped)ICHI has no code or block specifically for pharyngeal pouch (Zenker's diverticulum); searches for "pharyngeal pouch," "Zenker," "diverticulum" of the pharynx, and "hypopharynx" all return no procedural matches, and the cricopharyngeal myotomy (MAM.FB.AA) represents only one specific sub-procedure rather than the general operative category on pharyngeal pouch.
41853000 (Operation on pyriform sinus)(not mapped)ICHI has no dedicated code or block for the pyriform (piriform) sinus or hypopharynx as a surgical target; the pharynx blocks in ICHI cover nasopharynx and oropharynx only, leaving the hypopharynx/pyriform sinus without a direct structural match.
34969007 (Operation on retroperitoneum)(not mapped)ICHI contains no block or assignable code for interventions on the retroperitoneum as an anatomical target; the peritoneum block BlockL4-KMA covers the peritoneum and peritoneal cavity but explicitly excludes the retroperitoneal space, and no other block addresses it.
87471009 (Operation on temporal bone, middle fossa approach)(not mapped)ICHI contains no dedicated temporal bone surgery block and no code that captures the middle fossa surgical approach; mastoid procedures (CDA block) are the nearest ear/bone category but do not cover temporal bone operations accessed via middle cranial fossa craniotomy.
80012000 (Operation on urachus)(not mapped)ICHI contains only an anatomy extension code for the urachus (XA1NC2) but no procedural category or block covering interventions on the urachus; the structure is not represented as a surgical target in any assignable ICHI code.
43340002 (Operation on uterine ligament)(not mapped)ICHI does not contain a dedicated block or assignable category for interventions specifically on the uterine ligament; the term "XA4T57 Uterine ligament" exists only as an extension/qualifier code (target axis value) rather than a procedure grouping, and no procedure category scoped to this structure was found.
2607002 (Operation on uterus supporting structures)(not mapped)ICHI has no dedicated block or category for interventions on uterine supporting structures as a group; although "NME.GA.AA Destruction of uterus and supporting structures" mentions supporting structures, it represents only one specific action and does not cover the full scope of this SNOMED grouping concept.
175890004 (Operation on vascular graft)(not mapped)ICHI organises vascular interventions by the native vessel acted upon (artery, vein, specific region) rather than by graft type; there is no block or category specifically scoped to "operations on a vascular graft" as a target structure, making a reliable single-code match impossible.
371053008 (Operative procedure on cartilage)(not mapped)ICHI does not have a single unified block for interventions on cartilage across all body sites; instead, cartilage is organised into site-specific blocks (e.g., knee cartilage BlockL5-MMC, shoulder cartilage BlockL5-MDC, elbow cartilage BlockL5-MEC). The SNOMED concept is a generic, site-unspecified parent category with no adequate ICHI counterpart at that level of abstraction.
1287769002 (Operative procedure on upper arm)(not mapped)ICHI contains a block titled "Interventions on musculoskeletal structures of upper arm" but it has no retrievable block ID in the classification system, making it non-citable; no assignable category or properly identified block exists that covers operative procedures on the upper arm as a whole.
52051006 (Operative procedure on wrist and hand)(not mapped)ICHI splits wrist and hand into separate structural hierarchies (BlockL4-MFB for forearm/wrist and BlockL4-MGB for hand), with no combined block or category that covers both wrist and hand together.
243711000 (Optical low vision aid provision)(not mapped)ICHI does not have an assignable category code specifically for the provision of optical low vision aids; the classification contains only unassigned or structurally incomplete entries for assistive seeing products, and no existing category code adequately captures the clinical act of prescribing and fitting an optical low vision device.
281798001 (Oral fluid replacement)(not mapped)ICHI contains no code for oral fluid replacement or oral rehydration; the water/electrolyte balance block (BlockL5-ETE) only includes assessment and education codes, and no administration-by-mouth fluid replacement category exists in the classification.
385744008 (Oral fluid therapy management)(not mapped)Like oral fluid replacement, there is no ICHI category representing the management of oral fluid therapy; the nutritional substance administration codes (PZA.DA.*) cover intravenous and intracavity routes only, with no oral/enteral fluid administration code available.
1284927000 (Oral health program)(not mapped)ICHI contains no code for an oral health program as an organised health service delivery entity; the U-chapter (environment/services/policies) and related blocks cover health systems and services at a population level but have no dental- or oral-specific program code.
406906002 (Orange G stain method)(not mapped)ICHI does not classify specific histological staining techniques or dye-based staining methods at any level of granularity; Orange G is a laboratory reagent/technique with no corresponding ICHI code.
406907006 (Orange II stain method)(not mapped)Like Orange G, Orange II is a specific histological staining dye/technique with no corresponding ICHI representation; ICHI does not encode individual staining reagent methods.
271298009 (Organ retrieval operation)(not mapped)Exhaustive searching across synonyms (organ procurement, harvest, explant, donor, removal of organ) yielded no ICHI code representing the surgical retrieval of an organ from a donor; ICHI codes organ transplantation on the recipient side but does not classify the procurement/retrieval operation itself.
115307000 (Organism count)(not mapped)ICHI's Essential Laboratory Tests block contains specific named tests but has no code for a general organism/colony count procedure; this laboratory quantification method has no ICHI equivalent.
239368008 (Orthognathic surgery on photographs)(not mapped)This concept refers to pre-surgical photographic analysis for orthognathic surgery planning; ICHI has no code for photographic imaging or analysis of the jaw or facial skeleton, nor a planning-from-photographs concept.
239370004 (Orthognathic video imaging analysis)(not mapped)This concept describes video-based imaging analysis performed as part of orthognathic surgical planning; ICHI contains no code for video imaging analysis of the jaw or facial skeleton.
414980000 (Orthokeratology)(not mapped)Orthokeratology is a non-surgical vision correction technique using overnight rigid contact lenses to temporarily reshape the cornea; ICHI has no code for this procedure and the only related contact lens code refers to therapeutic bandage lenses, not refractive correction lenses.
385712009 (Ostomy care)(not mapped)ICHI contains codes for creating specific ostomies and an assistive-products entry for ostomy products, but has no code representing ongoing ostomy care or maintenance nursing as a health intervention in its own right.
183021004 (Oxygenation of slough)(not mapped)Refers to applying oxygen specifically to necrotic wound tissue (slough) as a wound care technique; ICHI has no code for topical or localised wound oxygenation, and the only oxygen-related code (PZA.DD.AC, systemic) is too distant for a reasonable match.
18921005 (Packed RBC preparation, sedimentation)(not mapped)Describes a blood banking / transfusion medicine procedure (processing whole blood by sedimentation to obtain packed red cells) which falls outside ICHI's scope of clinical health interventions. No ICHI code exists for blood component preparation.
406908001 (Page blue 83 stain method)(not mapped)"Page blue 83" is a specific histochemical staining reagent used in laboratory specimen preparation; ICHI does not include laboratory staining methods or histological technique codes.
406909009 (Page blue G-90 stain method)(not mapped)ICHI does not represent specific histological staining techniques (e.g., Page blue G-90) — it has no codes for dye/stain methods, and the nearest extension codes function as supplementary descriptors rather than classifiable procedure codes.
315165004 (Paraprotein typing by immunofixation)(not mapped)No ICHI code exists for immunofixation electrophoresis, paraprotein/monoclonal protein characterisation, or protein typing; the ICHI essential laboratory tests extension block covers select infectious disease and haematology markers but does not include protein characterisation techniques such as immunofixation.
60752001 (Parasite detection, blood)(not mapped)ICHI has no primary procedure code for general blood parasite detection; XG8RM3 Plasmodium spp. and XG06E8 Peripheral blood film examination exist only as extension/qualifier codes under the ICHI Extension Code chapter, not as assignable standalone procedure codes, and neither covers the full scope of blood parasite detection (protozoa, helminths, etc.).
26866009 (Partial avulsion)(not mapped)"Partial avulsion" is a morphological finding/injury descriptor in SNOMED CT (traumatic partial detachment of tissue), not a therapeutic procedure, and ICHI contains no code for avulsion as an intervention or for its repair. No reasonable ICHI procedural equivalent exists.
91485006 (Participation in ward rounds)(not mapped)Ward rounds are a clinician-to-clinician care coordination activity (not a health intervention delivered to a patient) and ICHI contains no code for a patient's participation in clinical rounds; no reasonable ICHI category covers this concept, which sits outside ICHI's scope of interventions performed on or for an individual patient.
67102000 (Patellaplasty)(not mapped)Patellaplasty refers to surgical reshaping or reconstruction of the patella, but ICHI contains no specific code for this — the MMP (Patella) block offers osteotomy, partial/total excision, graft, and stabilisation but no plasty/reconstruction procedure code applicable to the patella specifically.
448758009 (Patency capsule examination)(not mapped)A patency capsule examination is a diagnostic test in which a dissolvable capsule is swallowed to verify GI tract patency before capsule endoscopy; this distinct pre-procedure safety test has no corresponding ICHI code — KZZ.BA.AD covers camera capsule panendoscopy itself, which is a different procedure entirely.
406910004 (Patent blue V sodium salt stain method)(not mapped)This is a laboratory histological staining technique using a blue azo dye to identify lymphatic vessels or sentinel lymph nodes in tissue sections; ICHI does not include laboratory staining methods at this level of specificity, and no comparable code was found across any ICHI section.
12616003 (Patient discharge, escaped from custody)(not mapped)This SNOMED concept describes a purely administrative/legal discharge disposition (patient absconded while in legal custody) that has no procedural or clinical intervention correlate in ICHI; ICHI does not classify administrative status events, security incidents, or legal custody arrangements.
50861005 (Patient discharge, to legal custody)(not mapped)This concept represents an administrative discharge disposition — releasing a patient into legal or judicial custody — which is outside ICHI's scope; ICHI classifies health interventions performed on or for a person, not legal handover events or custodial transfers.
415045008 (Patient monitoring equipment check)(not mapped)ICHI has no code for checking or verifying the function of monitoring equipment in general; the closest specific code (HFC.SN.AH — Pacemaker or cardioverter defibrillator function check) is device-specific and far narrower in scope. No ICHI code captures the generic administrative/technical act of verifying that patient monitoring equipment is functioning correctly.
305215009 (Patient removal request procedure)(not mapped)ICHI has no code representing the administrative act of requesting removal of a patient from a list or care setting; XG38D0 (Discharge planning) exists only as an extension code under "Additional descriptive information" and describes planning rather than a removal request, making it unsuitable as a primary mapping.
184178003 (Patient self-deregistration)(not mapped)ICHI does not contain any code representing a patient-initiated act of withdrawing from or deregistering from a health service; this is a purely administrative event with no ICHI equivalent, and no related terms (withdrawal, deregistration, self-discharge, enrolment) returned any results in the classification.
252934004 (Percoll gradient centrifugation)(not mapped)Percoll gradient centrifugation is a laboratory technique for cell separation; ICHI contains no code for centrifugation, density-gradient separation, or sperm processing as a distinct procedure.
240290003 (Percutaneous aspiration of fetal ascites)(not mapped)ICHI has no code for aspiration of the fetal peritoneal cavity or fetal ascites; the fetal interventions block does not include a drainage/aspiration category for fetal body cavities.
1231783006 (Percutaneous closure of prosthetic cardiac paravalvular leak using device)(not mapped)ICHI contains no code for paravalvular or periprosthetic leak closure as a distinct intervention.
609173003 (Percutaneous cryoablation of neoplasm using computed tomography guidance)(not mapped)ICHI encodes destruction interventions with a mandatory body-site axis, so there is no site-agnostic "percutaneous destruction of neoplasm" code in the classification.
430286000 (Percutaneous fenestration of aorta using fluoroscopic guidance with contrast)(not mapped)No ICHI code exists for aortic fenestration (a procedure for aortic dissection); the aortic intervention block has no fenestration or flap-perforation category.
240285001 (Percutaneous insertion of fetal shunt)(not mapped)The ICHI fetal interventions block (NMR) contains no shunt insertion code; available codes cover infusion, valve dilatation, and endoscopic repair only.
429613009 (Percutaneous insertion of tracheal plug for congenital diaphragmatic hernia of fetus)(not mapped)No ICHI code for fetal tracheal balloon/plug occlusion (FETO); fetal block lacks combined percutaneous, tracheal target, and device occlusion in fetal context.
277585009 (Percutaneous magnetic resonance guided therapeutic drainage)(not mapped)ICHI has no body-site-agnostic "MRI-guided drainage" concept; all percutaneous drainage codes are anchored to a specific anatomical target.
1354587000 (Percutaneous transluminal radiofrequency ablation of hypertrophy of myocardium of septal region of left ventricle with angiography of coronary artery)(not mapped)ICHI has no code for percutaneous septal myocardial ablation (alcohol or radiofrequency) for hypertrophic obstructive cardiomyopathy; the myocardium block (HFD) only contains biopsy, nuclear imaging, and transmyocardial revascularisation codes, and no ablation-of-myocardium procedure exists anywhere in the classification. The compound nature of the SNOMED concept (ablation plus coronary angiography) makes an approximate single-code mapping additionally impractical.
370839001 (Performing required counts of procedure-related devices)(not mapped)ICHI does not contain a code for perioperative counting of surgical instruments, sponges, or devices — this is an administrative/safety process component of a surgical procedure rather than a classifiable health intervention in the ICHI framework. No relevant match was found across text searches, synonym searches, or browsing of safety/management/perioperative categories.
252684008 (Perfusion study - large intestine)(not mapped)ICHI does not contain a perfusion study (blood flow/nuclear medicine measurement) for the large intestine; the colon imaging codes (KBP block) cover X-ray, CT, MRI, and endoscopic ultrasound only, and no functional or scintigraphic perfusion assessment of the large intestine exists in ICHI.
252212009 (Pergonal stimulation test)(not mapped)Pergonal (menotropins, an FSH/LH preparation) stimulation is a specific endocrine provocation test with no corresponding ICHI category; ICHI provocation tests are limited to conjunctival, nasal, bronchial, and food challenges, and no gonadotropin or hormonal stimulation test code exists.
390819005 (Perinatal mental health care)(not mapped)ICHI has no perinatal-specific mental health care code; the classification does not organise interventions by patient population (e.g., perinatal), and the SNOMED concept represents a broad multidisciplinary care programme that spans assessment, counselling, and treatment, none of which maps precisely to a single ICHI category.
718335006 (Perioperative injury care management)(not mapped)ICHI does not contain a code for perioperative injury care management as a distinct concept; no assessment, management, or care category addressing intraoperative or perioperative injury was found, and no sufficiently close approximation exists across the classification.
278733007 (Perioral incision)(not mapped)ICHI has no assignable category for an incision of the perioral region; while XA1A48 identifies "Perioral region" as an extension code (anatomical target modifier), there is no lip or perioral incision category in the lip block (KAA) or any adjacent block, and no combination code exists that specifically represents this procedure.
120196009 (Peritoneum manipulation)(not mapped)ICHI contains no code for manipulation of the peritoneum; the peritoneum block (BlockL4-KMA) does not include a manipulation action (LD axis), and the manipulation codes that do exist in ICHI are restricted to intestinal and musculoskeletal structures.
406911000 (Permethrin stain method)(not mapped)Permethrin staining is a histological laboratory technique used to identify arthropod structures (e.g., scabies mites), and ICHI contains no laboratory staining or ectoparasite detection codes; this diagnostic method falls outside ICHI's intervention scope entirely.
82943004 (Phenolphthalein measurement, feces)(not mapped)Phenolphthalein measurement in feces is a specific analytical/chemical test (used to detect laxative abuse); ICHI contains no code for chemical analysis of stool, and the only feces-related ICHI code (PZX.AH.XG, Specimen collection of faeces) covers only specimen collection, not measurement or analysis.
406912007 (Phloxin B stain method)(not mapped)Phloxin B staining is a bench-level laboratory histology technique; ICHI does not classify laboratory staining methods, which fall outside its scope of clinical health interventions.
410186001 (Physical evaluation education)(not mapped)No ICHI code exists for educating a patient about their physical evaluation or the process of clinical assessment; ICHI's education action codes (PM axis) are all tied to specific body functions or health behaviours, and there is no target axis representing "physical evaluation" as a subject of education.
424291000 (Physical therapy surveillance)(not mapped)ICHI has no code for ongoing surveillance or monitoring of physical therapy progress as a distinct administrative or clinical act; ICHI public health surveillance codes refer to population-level surveillance of environmental or disease phenomena, not patient-level physical therapy follow-up.
410147000 (Physician status report education)(not mapped)This concept refers specifically to education about how to produce or interpret a physician status report — a meta-activity with no reasonable ICHI counterpart. ICHI "advising" and "training" codes are scoped to clinical functions and conditions, not to documentation tasks or procedural literacy.
410148005 (Physician status report management)(not mapped)This concept concerns the administrative management of physician status reports as documents, which falls entirely outside ICHI's scope of health interventions on patients. No ICHI code captures management of clinical documentation products.
169267005 (Physics - other measurements)(not mapped)This SNOMED concept refers to physical/physics-based measurements (e.g., radiation dosimetry, audiometric physics) that do not map to any specific ICHI category. ICHI's measurement codes are anatomy- or function-specific, and no residual "other physical measurements" code exists at an appropriate level of generality.
183127003 (Physiological hearing assistance)(not mapped)"Physiological hearing assistance" refers to the provision or fitting of hearing aids/amplification devices to support hearing function; ICHI has no specific code for fitting or dispensing hearing assistive products — the hearing blocks (CTB) cover assessment, testing, and education only, and the assistive product installation codes do not capture the hearing-specific functional intent.
281691001 (Physiological monitoring regime)(not mapped)ICHI does not have a generic "physiological monitoring regime" code; its monitoring codes (action AI) are all tied to specific body systems or functions. The SNOMED concept refers to a broad, undifferentiated monitoring regimen with no meaningful ICHI equivalent at that level of generality.
787139004 (Piecemeal excision)(not mapped)"Piecemeal excision" is a technique modifier (describing how a lesion is removed in multiple fragments) rather than a procedure tied to a specific target or action axis in ICHI. ICHI has no generic "piecemeal" or "fragmentation" excision category applicable across body sites.
177594004 (Piercing of ear lobe)(not mapped)ICHI does not contain a code for cosmetic ear piercing; the external ear block (CAA) covers biopsy, drainage, excision, reconstruction, and dressing but not deliberate perforation for cosmetic or cultural purposes.
74082008 (Pin/tong site care)(not mapped)Pin/tong site care refers to wound and skin care around skeletal traction pins or skull tongs — a nursing intervention with no dedicated ICHI code. Searches across wound care, dressing, skin management, device management, traction, and fixator terms returned no applicable match.
228117001 (Placement on child register)(not mapped)"Placement on child register" is an administrative safeguarding action (adding a child to a child protection or at-risk register) with no corresponding concept in ICHI, which does not cover administrative registration or child safeguarding procedures.
241355001 (Placenta isotope study)(not mapped)ICHI contains no imaging or isotope/radionuclide scan code specifically targeting the placenta — the NMM block contains only procedural interventions (biopsy, drainage, removal, etc.) with no scintigraphy or radioisotope study entry. The closest radionuclide codes target entirely different organs.
166430001 (Placental function test)(not mapped)ICHI has no code for functional assessment of the placenta; the NMM block contains only surgical/procedural interventions and no assessment or function-test category. The three radioisotope function study codes in ICHI (thyroid, liver, whole body) are organ-specific and semantically incompatible.
1331916001 (Plain X-ray guided biopsy)(not mapped)ICHI does not have a cross-cutting "plain X-ray guided biopsy" category; while extension code XG2RR6 ("X-ray guided") exists for qualifying means and body-site-specific percutaneous biopsy codes are available, no single assignable code captures plain radiographic guidance with a non-site-specific biopsy.
711225005 (Plain X-ray guided injection)(not mapped)ICHI structures injection codes by specific anatomical target (e.g., injection into spinal canal, injection into peripheral nerve), so there is no generic "injection" code that would correspond to this target-unspecified SNOMED concept; assigning any target-specific ICHI injection code would be an unjustifiable narrowing.
1290417007 (Plain X-ray of lymph node)(not mapped)ICHI contains no plain X-ray code for lymph nodes; the only lymph node imaging codes are lymphograms (contrast-based) and ultrasound, none of which represent a non-contrast plain radiograph.
398207008 (Plan and risks education)(not mapped)No ICHI code exists for generalized education about a treatment plan and its associated risks as a standalone intervention type. The nearest ICHI "education" codes are all tied to specific body functions or body system targets.
412987003 (Plasma B-hexosaminidase measurement)(not mapped)ICHI's essential laboratory tests block does not include lysosomal enzyme assays such as beta-hexosaminidase (used in Tay-Sachs/Sandhoff disease screening), and no broader enzyme measurement category exists in ICHI that would serve as a reasonable match.
407682008 (Plasma vitamin B12 level)(not mapped)ICHI contains no codes for vitamin or micronutrient serum/plasma level measurements; searches for "vitamin", "cobalamin", "B12", and broader metabolic or nutritional measurement categories did not yield any suitable match.
450711008 (Plastic repair of extraarticular ligament)(not mapped)ICHI ligament repair codes are all tied to specific anatomical locations (knee, hand/finger, foot/toe, wrist, etc.) with no generic cross-site extraarticular ligament repair code. The SNOMED concept is a body-site-unspecified category, and no ICHI equivalent exists at that level of abstraction.
52710002 (Plastic repair with excision of tissue)(not mapped)This SNOMED concept is a high-level, generic category describing a combined excision-and-repair technique applicable across many body sites and tissue types; ICHI organises interventions by body site rather than by generic procedural category, and no single ICHI code captures this cross-cutting combination.
54621003 (Plastic repair with reduction)(not mapped)This is an abstract procedural category (reduction-type plastic repair on unspecified tissue/body part) that does not map to any single ICHI code; ICHI encodes reduction procedures at specific body sites, and there is no generic cross-site "plastic repair with reduction" code.
85340000 (Polarographic measurement)(not mapped)Polarographic measurement is a specific electrochemical technique for measuring dissolved oxygen or other analytes (e.g., transcutaneous oxygen tension), and no corresponding code exists in ICHI — searches for polarographic, oxygen measurement, blood gas, transcutaneous, pulse oximetry, and respiratory measurement all returned no semantically adequate match at this level of specificity.
184967007 (Police request to attend and examine)(not mapped)This SNOMED concept describes a UK primary care administrative context — a clinician responding to a formal police request to examine a person — which has no equivalent in ICHI; the classification does not contain codes for medicolegal attendance requests, and searches across forensic, legal, police, court, and physical examination terms confirmed no suitable mapping.
440716007 (Polymerase chain reaction test for Pneumocystis)(not mapped)ICHI's essential laboratory tests block contains no code for Pneumocystis detection by any method, and no relevant nucleic acid amplification or fungal detection code exists in the classification; the only potentially comparable code (XG4U02, Viral nucleic acid amplification test) is scoped to viruses, whereas Pneumocystis jirovecii is a fungus.
406913002 (Ponceau 3R stain method)(not mapped)ICHI contains no codes for specific histological or protein staining dye methods. Ponceau 3R is a specific azo dye staining technique with no representable equivalent anywhere in the ICHI classification, including the laboratory extension section (XG), which covers only a narrow set of essential clinical laboratory tests.
406914008 (Ponceau S stain method)(not mapped)ICHI contains no codes for specific histological or protein staining dye methods. Ponceau S is a specific azo dye used for protein detection in tissue staining and Western blotting, and no ICHI code exists at this level of granularity in any section of the classification.
406915009 (Ponceau xylidine stain method)(not mapped)ICHI contains no codes for specific histological or protein staining dye methods. Ponceau xylidine is a specific dye staining variant with no representable equivalent in ICHI; the classification's laboratory extension (XG) does not cover histological staining techniques at any level of specificity.
406916005 (Pontamine sky blue 5BX stain method)(not mapped)ICHI contains no codes for specific histological dye staining methods. Pontamine sky blue 5BX is a specific direct dye used in connective tissue and neuroanatomical staining, with no equivalent or approximate code anywhere in the ICHI classification.
406917001 (Pontamine sky blue 6BX stain method)(not mapped)ICHI contains no codes for specific histological dye staining methods. Pontamine sky blue 6BX is a specific direct dye variant with no equivalent or approximate code anywhere in the ICHI classification; the level of granularity these SNOMED concepts represent is simply not present in ICHI.
441428007 (Position call light near subject)(not mapped)Placing a call light within reach of a patient is a nursing/bedside safety task with no corresponding ICHI category; ICHI does not classify at this level of specific item-placement activity, and no assistive product installation or environment modification code comes close to this concept.
736169004 (Post anesthesia care management)(not mapped)ICHI contains codes for administering anaesthesia and generic health management encounter codes, but has no code representing post-anaesthesia care or recovery room management as a distinct intervention. The concept of monitoring and managing a patient in the immediate post-anaesthesia period is not represented at any level of the ICHI hierarchy.
171067001 (Postnatal support group)(not mapped)ICHI does not contain a code for a postnatal or perinatal support group; peer support codes (RE action axis) are tied to specific functional domains rather than a general postnatal group setting, and no combination of available codes adequately represents this community-based psychosocial intervention for postpartum individuals.
314606007 (Postoperative course of deep X-ray therapy)(not mapped)ICHI organises radiotherapy codes by the anatomical target site (e.g., "Destruction of lesion of brain by radiotherapy") with no generic "deep X-ray therapy" or orthovoltage radiotherapy code, and it does not encode postoperative care phases as discrete interventions. No reasonable single ICHI code captures this concept.
225221000 (Praising)(not mapped)Praising is a behavioural reinforcement technique (e.g., used in nursing or therapy to encourage patient behaviour) that has no corresponding ICHI category; ICHI does not represent positive reinforcement or praise as a distinct intervention.
1137457009 (Pre-exposure prophylaxis)(not mapped)ICHI contains no code for pharmaceutical chemoprophylaxis (e.g. antiretroviral PrEP for HIV prevention); vaccination codes cover immunological prophylaxis only, and behavioural/sexual health blocks address behaviour change rather than drug administration for prevention before exposure.
29537000 (Preoperative shaving of skin)(not mapped)ICHI contains no code for hair removal, depilation, or shaving of skin; this perioperative preparatory procedure (mechanical hair removal prior to surgery) is not represented in the ICHI classification.
51949007 (Preparation and centrifugation of packed red blood cells)(not mapped)ICHI's blood block (DIA) covers transfusion, collection, apheresis, and specimen collection of blood, but contains no code for the laboratory processing step of preparing or centrifuging packed red blood cells; this blood bank preparation activity is outside ICHI's representable scope.
223495004 (Preparation of patient for procedure)(not mapped)ICHI contains no code representing pre-procedural patient preparation as a distinct intervention (e.g., fasting instructions, consent, positioning, surgical site marking); its coverage begins at the procedure itself, and there is no perioperative/preoperative preparation category in any block.
85227008 (Preparation of standardized bacterial suspension)(not mapped)ICHI has no codes covering laboratory bench procedures such as preparing microbial inocula or standardized suspensions (e.g., McFarland standards); this is a pre-analytical laboratory activity outside ICHI's scope of health interventions delivered to or for a patient or population.
386396004 (Preparatory sensory information)(not mapped)"Preparatory sensory information" is a nursing intervention in which a patient is given concrete, sensory-focused information about what a procedure will feel, sound, or smell like, in order to reduce anxiety; ICHI has no category for this specific type of pre-procedural psychological preparation.
11200006 (Prescribing corneal contact lens)(not mapped)ICHI has no code for prescribing a corrective corneal contact lens; the only contact-lens code (BBB.DK.AH) is specifically for application of a therapeutic bandage lens to the cornea, which is a different clinical act. The prescription codes under the UA block do not extend to optical contact lenses.
6213004 (Prescribing corneoscleral contact lens)(not mapped)As with corneal contact lens prescribing, ICHI contains no code covering the prescription of corneoscleral (scleral) contact lenses for optical correction; the clinical act falls outside ICHI's modelled scope for this category of intervention.
25431006 (Prescribing, fitting and revision of contact lens)(not mapped)This compound act (prescribing, fitting, and revising contact lenses) has no counterpart in ICHI; no block or category covers optical contact lens prescribing or fitting, and the only relevant code (BBB.DK.AH) is restricted to therapeutic bandage lens application rather than corrective lens management.
225359006 (Pressure area care)(not mapped)ICHI contains no code for pressure ulcer/pressure area care as a distinct nursing or wound-management intervention; searches across skin care, wound care, decubitus, and tissue integrity yielded no suitable match, and the closest fuzzy results (acupressure, pressure-relief assistive products) are semantically unrelated.
302805002 (Preventive monitoring)(not mapped)"Preventive monitoring" is a high-level administrative/organisational SNOMED concept with no direct ICHI counterpart; ICHI monitoring codes (action axis AI) are all tied to specific body targets or functions and there is no generic "preventive monitoring" or "health surveillance" category in the clinical intervention chapter.
281653001 (Pricking blister)(not mapped)ICHI has no code for blister puncture/pricking as a distinct procedure. Pricking a blister is too granular and procedure-specific to map to any available ICHI category; the closest ICHI concepts (percutaneous drainage of skin, incision of skin) do not capture the distinct clinical meaning.
737470001 (Primary care management)(not mapped)ICHI does not contain a code representing a primary care management encounter or consultation at the patient level; the U-chapter health services codes operate at a systems/policy level and are not semantically equivalent to a clinical primary care management activity.
179730002 (Primary prosthetic replacement of multiple ligaments)(not mapped)ICHI has no code covering prosthetic replacement of multiple ligaments and no generic multi-site ligament procedure code; all ICHI ligament reconstruction codes are region- or joint-specific, and none addresses the prosthetic replacement of multiple ligaments as a distinct concept.
179761006 (Primary reattachment extra-articular ligament)(not mapped)All ICHI ligament reattachment codes are site-specific (shoulder, elbow, wrist, foot, etc.) and none is designated as extra-articular; there is no generic or extra-articular ligament reattachment code in ICHI that could serve as a reasonable match for this unlocalized SNOMED concept.
445196004 (Probiotic therapy)(not mapped)Extensive searching across probiotic, microbiome, dietary supplement, gut flora, bacteria, biologic therapy, nutritional, and oral medication terms yields no ICHI code capturing the administration of live microbial preparations as a therapeutic intervention. ICHI does not appear to have a category for probiotic therapy.
118888001 (Procedure on aortic body)(not mapped)The aortic body is a chemoreceptor/paraganglionic structure anatomically distinct from the aortic vessel; ICHI has no dedicated block or category for aortic body, paraganglia, or analogous chemoreceptor tissue, and no reasonable surrogate code exists.
129234005 (Procedure on aponeurosis)(not mapped)ICHI has no site-unspecified aponeurosis code or block; fascia-related codes exist only per body region (e.g., shoulder, forearm, hand) and there is no grouping block that generalises across all aponeurosis/fascia sites matching this broad SNOMED concept.
129183000 (Procedure on bone of extremity)(not mapped)ICHI distributes bones of the extremities across multiple region-specific blocks (shoulder, upper arm, forearm, hand, thigh, lower leg, foot) with no single block or category that unifies all bones of both upper and lower extremities; the only generic bone block (BlockL5-MRB, unspecified site) does not restrict to extremities, so no reasonable single-code match exists.
118866001 (Procedure on broad ligament)(not mapped)ICHI has no dedicated block or assignable category for interventions on the broad ligament of the uterus; the nearest anatomical reference in ICHI is an extension/axis code (XA0EJ9 "Broad ligament of the uterus") which is a target-axis qualifier, not a procedure code. No block in the female genital system section (NMA–NMS) covers the broad ligament as a distinct target.
118873006 (Procedure on epididymis)(not mapped)ICHI does not contain a dedicated block or category for interventions on the epididymis; the structure is subsumed under BlockL5-NGD (spermatic cord), and the only epididymis-specific ICHI code (NGD.BA.BB, contrast epididymogram) is a single narrow imaging procedure, not a grouper for all epididymis procedures.
118691003 (Procedure on face)(not mapped)ICHI has no dedicated block or category for "the face" as a unified anatomical region — procedures on the face are distributed across separate blocks for facial bone (MAB), soft tissue of head/neck (MAS), eyelid/orbit (BAA/BAM), skin, and vessels, none of which individually represents a "procedure on face" in the broad SNOMED sense.
118791009 (Procedure on hypopharynx)(not mapped)ICHI has no dedicated block or category for interventions on the hypopharynx (laryngopharynx); the structure appears only as a body-part extension code (XA2J67) with no associated intervention category. The nearest pharyngeal intervention blocks cover nasopharynx (BlockL5-JAM) and oropharynx (BlockL5-KAR) but not the hypopharynx specifically.
129182005 (Procedure on joint of lower extremity)(not mapped)ICHI organises lower extremity joint interventions by specific anatomical site (hip, knee, ankle, foot/toe, pelvic region) with no single block or category covering "joint of lower extremity" as a group; the generic joint block (BlockL5-MRJ, joint unspecified site) does not carry lower-extremity specificity and is semantically too distant.
129181003 (Procedure on joint of upper extremity)(not mapped)ICHI organises upper extremity joint interventions by specific site (shoulder, elbow, wrist, hand/finger) with no single block or category that groups all upper extremity joints together; no existing ICHI code or block reasonably represents the aggregate concept "procedure on joint of upper extremity."
129172009 (Procedure on nail)(not mapped)ICHI separates nail interventions into two distinct blocks — "Interventions on nail of finger" (BlockL5-LBD) and "Interventions on nail of toe" (BlockL5-LBF) — with no single superordinate block for nail in general, so the anatomically non-specific SNOMED concept cannot be mapped to a single ICHI code without loss of precision or arbitrary choice.
118879005 (Procedure on nerve)(not mapped)ICHI separates nerve interventions into distinct blocks for cranial nerves (AAN), spinal nerves (ABN), and peripheral nerves (ACA), with no overarching single block or code for "nerve" generically. The SNOMED concept is a top-level grouper spanning all nerve types and all procedure types, which cannot be represented by any one ICHI code or block without significant distortion.
281769000 (Procedure on origin of tendon)(not mapped)ICHI organises tendon interventions by anatomical region (trunk, shoulder, forearm, hand, thigh, etc.) and does not have any block or category that targets the tendon's point of origin (enthesis/musculotendinous attachment) as a distinct anatomical target. No ICHI code captures this SNOMED concept at any level of granularity.
118801009 (Procedure on papillary muscle of heart)(not mapped)ICHI has no dedicated block or assignable category for procedures on the papillary muscle of the heart; the only ICHI references to papillary muscle are extension/anatomy codes, not procedure targets. The nearest structural blocks (heart valves HDE, heart ventricle HBA) cover related anatomy but do not represent procedures specifically on the papillary muscle.
118865002 (Procedure on round ligament)(not mapped)ICHI has no dedicated block or assignable category for procedures on the round ligament of the uterus; the closest structural groupings (NME — uterus, NME.ML — reconstruction of uterus and surrounding structures) are too semantically distant and broad to constitute a reasonable match for this specific anatomical target.
129211001 (Procedure on smooth muscle)(not mapped)ICHI has no intervention block or category targeting smooth muscle as a tissue type; XA0JY3 ("Smooth muscle") exists only as an extension/anatomy code used to qualify other interventions, not as a standalone intervention class, and ICHI's muscle intervention blocks are all organised around skeletal muscle by anatomical region.
434288009 (Procedure on tissue block)(not mapped)SNOMED 434288009 refers to laboratory-based procedures performed on a fixed tissue block (a physical specimen processed for histological examination), which is a concept from the pathology/lab domain; ICHI does not contain a code for procedures on tissue blocks as objects, and the closest related concept (XG30Q5 Histopathology) is an ICHI extension code for a broader process, not a direct match.
118702008 (Procedure on upper extremity)(not mapped)ICHI does not have a single code or block that covers all interventions on the upper extremity as a whole; procedures are distributed across multiple separate blocks by sub-region (shoulder, elbow, forearm, hand) and tissue type (musculoskeletal, vascular, skin), with no unifying "upper extremity" grouper block. The SNOMED concept is a high-level administrative grouper with no viable ICHI equivalent.
225167009 (Procedure using leeches)(not mapped)ICHI contains no code for leech therapy (hirudotherapy); searches for "leech," "hirudotherapy," "bloodletting," and "biotherapy" all returned no results. The PZX block contains related traditional medicine approaches (cupping, moxibustion, acupuncture) but nothing covering leeches.
406918006 (Procion brilliant blue MRS stain method)(not mapped)This SNOMED concept describes a specific histological staining method (a reactive dye used in muscle fibre typing); ICHI has no codes for staining techniques or specific laboratory methods at this level of granularity. Searches for "stain," "dye," "histology," and "microscopy" returned no applicable results.
55149002 (Procurement of patient informed consent, investigational study)(not mapped)ICHI does not cover administrative or legal documentation processes such as obtaining informed consent for research; comprehensive searching across consent, agreement, documentation, clinical trial, and research terms returned no relevant codes, confirming this concept falls outside ICHI's scope.
243118002 (Professional reassurance)(not mapped)ICHI has no concept for "reassurance" as a distinct intervention; the closest candidates (counselling and emotional support codes) each capture only one narrow facet of professional reassurance and would misrepresent the SNOMED concept. No single ICHI code covers the act of a clinician providing professional reassurance regardless of body system or psychological domain.
183020003 (Promotion of healing with positive pressure)(not mapped)ICHI contains no codes for positive pressure therapy, hyperbaric treatment, wound healing promotion, or any pressure-based wound care intervention; the concept does not correspond to any identifiable ICHI category or block.
720007002 (Prostate cancer care review)(not mapped)ICHI does not include clinical care reviews, disease management reviews, or structured follow-up review encounters — these are administrative/clinical coordination activities outside ICHI's scope of health interventions. No prostate-cancer-specific review code exists anywhere in the classification.
386402007 (Prosthesis care)(not mapped)ICHI contains only body-part-specific prosthesis management codes (e.g., BZZ.SM.AH for ocular prosthetics, CBA.SM.AC for middle ear prosthetic device) with no generic cross-anatomical "prosthesis care" code. Selecting any single body-part code would misrepresent the broad, unspecified SNOMED concept, so no mapping is assigned.
79076007 (Prosthetic readjustment)(not mapped)ICHI has no code representing readjustment, refitting, or fine-tuning of an existing prosthesis as a standalone procedure; action codes for device management exist only as axis-level concepts without a generic assignable category code that captures prosthetic readjustment across all prosthesis types.
226050009 (Prosthetic rehabilitation)(not mapped)ICHI does not have a single assignable code for prosthetic rehabilitation as a generic concept; relevant ICHI content is fragmented across activity-specific training codes and installation of assistive product codes, none of which comprehensively represents the full scope of prosthetic rehabilitation.
1260284000 (Prosthetic reinforcement of extra-articular ligament)(not mapped)ICHI encodes ligament reconstruction only at specific anatomical sites and has no action for "reinforcement" as distinct from reconstruction or repair; there is no unspecified-site ligament reconstruction code and no code that distinguishes extra-articular from intra-articular ligament augmentation with prosthetic material.
265205006 (Prosthetic repair of ligament)(not mapped)ICHI ligament repair and reconstruction codes represent biological repair or reconstruction only and do not incorporate a prosthetic/artificial device implant. No generic "prosthetic repair of ligament" concept exists across body sites, and ICHI ligament codes are body-site-specific.
450778008 (Prosthetic replacement of extraarticular ligament)(not mapped)ICHI has no codes for prosthetic/artificial ligament implantation for any ligament type; the closest available codes involve biological reconstruction or repair of ligaments at specific body sites. The specific concept of replacing an extraarticular ligament with a prosthesis has no corresponding ICHI category.
433456006 (Protease digestion of tissue specimen)(not mapped)Protease digestion is a laboratory histopathology pre-analytic technique applied to tissue specimens, and ICHI does not include codes for laboratory specimen processing or enzymatic treatment methods; no reasonable ICHI match exists.
372921003 (Providing care according to standard)(not mapped)"Providing care according to standard" is a meta-concept describing adherence to clinical guidelines during any care delivery, not a specific health intervention. ICHI contains no code for this process concept, as it classifies discrete interventions rather than compliance with protocols.
424613007 (Provision of activity privileges)(not mapped)"Provision of activity privileges" is a care-plan or administrative concept (granting a patient permission to perform certain activities) for which no ICHI code or block corresponds; ICHI does not model the granting of clinical permissions or activity entitlements as a coded intervention.
716343008 (Provision of child development learning activity)(not mapped)ICHI covers "basic learning" interventions and "practical support with acquiring skills," but none specifically represent the structured provision of child development learning activities, and the relevant block codes are flagged as incomplete; no sufficiently close assignable ICHI code exists.
276911009 (Provision of Cunningham penile clamp)(not mapped)A Cunningham clamp is a non-surgical external urinary incontinence management device applied to the penis. No ICHI category covers provision or fitting of an external penile compression device; the genitourinary and incontinence sections in ICHI address surgical procedures, implantable devices, and absorbent products but not external occlusion aids of this type.
719570003 (Provision of diabetes identity card)(not mapped)ICHI contains no concept for providing a disease-specific identity or alert card; the classification does not cover administrative/documentation tools such as patient identification cards for specific conditions. No reasonable broader match exists that captures the specific nature of supplying a diabetes identity card as a clinical act.
445034001 (Provision of emesis basin)(not mapped)An emesis basin is a single-use disposable clinical supply item (container for vomit/sputum). ICHI does not classify the provision of disposable clinical supplies or receptacles, and no code in the classification covers this activity even at a broader level.
699117005 (Provision of leaflet)(not mapped)ICHI does not have a code for providing printed health information materials such as leaflets or pamphlets; its information-related codes cover training, education sessions, and advising as interactions rather than the supply of printed goods.
711124002 (Provision of patient satisfaction questionnaire)(not mapped)ICHI contains no codes for administering, distributing, or providing patient satisfaction questionnaires or patient-reported outcome instruments; this is an administrative/quality improvement activity that falls outside ICHI's classification scope.
1338044007 (Provision of refrigerator)(not mapped)ICHI does not contain any code for provision of a household appliance such as a refrigerator; the classification has no environmental or asset-provision code that maps to supplying a domestic appliance.
715934000 (Provision of registered midwife patient escort)(not mapped)ICHI contains no concept for a clinical escort service provided by a midwife or other health professional; the classification does not classify the act of accompanying a patient between locations as a distinct health intervention.
715937007 (Provision of specialist retrieval service anesthetist patient escort)(not mapped)ICHI has no code representing the organisation or provision of a specialist retrieval/transport service with anaesthetist escort; this operational/logistics concept sits outside ICHI's scope.
699835004 (Provision of written information about colposcopy)(not mapped)No ICHI education code exists for the female genital system, the cervix uteri, or colposcopy as a procedure; no suitable approximate match could be identified.
699838002 (Provision of written information about hysteroscopy)(not mapped)ICHI does not have a code for patient education or information provision specifically about a clinical procedure such as hysteroscopy; available uterus education codes target functions, not pre-procedure written information.
699839005 (Provision of written information about lower gastrointestinal tract endoscopy)(not mapped)ICHI has no code for patient education or information provision about a gastrointestinal endoscopic procedure; the digestive system education code addresses functions, not pre-procedural written information.
699831008 (Provision of written information about upper gastrointestinal tract endoscopy)(not mapped)ICHI contains no code for providing written information about a procedure; codes for the endoscopic procedure itself describe doing the procedure, not informing a patient about it.
304418001 (Pulsed electromagnetic energy to back)(not mapped)ICHI contains no codes for electromagnetic, pulsed shortwave, or similar energy-based physical therapy modalities; the musculoskeletal back soft-tissue block (MCS) only includes massage and stretching.
304417006 (Pulsed electromagnetic energy to hand)(not mapped)ICHI lacks any electromagnetic or pulsed energy therapy codes; the hand musculoskeletal block (MGB/MGM) covers only surgical and mechanical interventions, with no energy-delivery modality applicable to the hand region.
304411007 (Pulsed electromagnetic energy to neck)(not mapped)ICHI does not classify pulsed electromagnetic energy therapy as a distinct intervention category; the soft tissue of head or neck block (MAS) only provides imaging, massage, and stretching codes.
304412000 (Pulsed electromagnetic energy to trunk)(not mapped)ICHI contains no codes for electromagnetic field therapy, pulsed electromagnetic energy, or equivalent physical-agent modalities applied to any body region; the closest available trunk-level interventions are massage/stretch of soft tissue of trunk, which are semantically distinct.
443803004 (Puncture and aspiration of cyst)(not mapped)ICHI organises aspiration procedures by specific target organ (orbit, gallbladder, bladder, prostate, testes) and has no generic site-unspecified "aspiration of cyst" code.
2078009 (Puncture of bursa of hand)(not mapped)ICHI has no procedural category combining a bursa target with a puncture/aspiration action at the hand; the bursa extension codes (XA16K5 etc.) exist only as target axis qualifiers, not as assignable intervention categories.
252299004 (Pyruvate kinase deficiency spot test)(not mapped)ICHI contains no code for enzyme assay or spot testing for red cell enzyme deficiencies; the Essential laboratory tests block (XG1) covers only a narrow set of WHO-prioritised tests and does not include this assay.
117727003 (Quantitation of bacteria)(not mapped)ICHI's essential laboratory tests block (XG1) contains genus/species identification of bacteria but no code for quantitative enumeration (colony count) of bacteria.
441823008 (Quantitative measurement of amino acid in cerebrospinal fluid specimen)(not mapped)ICHI has a code for specimen collection from the spinal canal (ABG.AH.XE) and recognises CSF (XA1N55) as a target extension, but no assignable code for quantitative amino acid analysis in CSF or any body fluid.
444006004 (Quantitative measurement of calprotectin in stool specimen)(not mapped)ICHI has a code for specimen collection of faeces (PZX.AH.XG) but no code representing the quantitative analytic measurement of a specific protein analyte (calprotectin) in stool.
444223000 (Quantitative measurement of creatinine in peritoneal fluid specimen)(not mapped)ICHI contains KMA.AH.XE (specimen collection of peritoneal fluid) and XG94P6 (Creatinine extension code) but no assignable procedure code representing the quantitative measurement of a specific analyte in peritoneal fluid.
444005000 (Quantitative measurement of mass content of cocaine metabolite in meconium specimen using gas chromatography mass spectrometry)(not mapped)ICHI contains no toxicological drug assay codes, no meconium specimen codes, and no codes for chromatography or mass spectrometry techniques.
11758005 (Quantitative photoplethysmography, venous)(not mapped)Photoplethysmography is an optical/light-based measurement of venous blood volume changes; ICHI has no code for photoplethysmography in any form, and there is no vascular imaging code that captures this optical technique.
117326009 (Quinacrine fluorescent stain method)(not mapped)Q-banding (quinacrine fluorescent chromosome staining) is a cytogenetic laboratory technique; ICHI contains no codes for chromosome analysis, cytogenetics, histological staining methods, or fluorescence microscopy procedures.
278747006 (Racquet incision)(not mapped)A racquet incision is a surgical incision shape used in digit/limb amputation or skin-lesion excision; ICHI codes capture the amputation or excision itself without encoding the incision pattern.
1148692008 (Radiation therapy following chemotherapy)(not mapped)ICHI encodes individual interventions but has no code representing a sequenced treatment protocol combining chemotherapy followed by radiotherapy; the temporal sequencing cannot be represented by any single ICHI code.
26802008 (Radiation therapy isodose plan, arc field)(not mapped)ICHI contains no codes for radiation therapy treatment planning, isodose calculation, or beam-delivery technique design; the classification only encodes the delivery act itself, not pre-treatment dosimetry/planning activities.
32947004 (Radiation therapy isodose plan, isocentric)(not mapped)ICHI has no codes for radiotherapy treatment planning activities or isodose computation methods; "isocentric" describes a beam-geometry technique used in planning, falling entirely outside ICHI's representable scope.
49963009 (Radiation therapy isodose plan, moving strip field)(not mapped)ICHI does not classify radiation therapy planning procedures or field-delivery techniques such as moving strip fields; searches for "isodose," "dosimetry," "treatment planning," and "external beam" returned no results.
84336003 (Radiation therapy isodose plan, rotation field)(not mapped)Rotation field planning is a specific isodose calculation technique for radiotherapy delivery; ICHI encodes only the resulting therapeutic acts and not the preparatory dosimetric planning activities.
113115007 (Radiation therapy isodose plan, wedge fields)(not mapped)Wedge field planning is a dosimetry technique used in pre-treatment radiotherapy planning; ICHI contains no planning, dosimetry, or beam-modifier codes.
31344000 (Radiation therapy treatment planning, patient contour and localization of internal structures)(not mapped)This SNOMED concept describes a highly specific sub-task of radiation therapy treatment planning — acquisition of patient body contour and internal structure localization — and no equivalent ICHI code or block exists for this preparatory computational/planning activity.
87390000 (Radiation therapy, central axis depth dose computation)(not mapped)Central axis depth dose computation is a dosimetry calculation step within radiation therapy planning; ICHI contains no codes for dosimetry, beam computation, or any radiation therapy planning sub-tasks.
57966002 (Radiation therapy, tissue and geometric inhomogeneity correction)(not mapped)Tissue and geometric inhomogeneity correction is a physics-level computational adjustment applied during radiation therapy dose calculation; ICHI does not classify these technical sub-procedures of radiotherapy planning.
62141006 (Radical excision)(not mapped)ICHI encodes radical excision only as site-specific codes and has no generic body-site-unspecified "radical excision" category; the SNOMED concept is a procedure category without a body-site specification, making a valid single ICHI assignment impossible.
709588001 (Radiofrequency ablation using fluoroscopic guidance)(not mapped)This SNOMED concept describes a guidance modality applied to radiofrequency ablation without specifying a body target; ICHI has no body-system-agnostic "RFA with fluoroscopic guidance" code.
433058002 (Radiofrequency ablation using ultrasound guidance)(not mapped)Like the fluoroscopy-guided variant, this is a procedure modifier without a specified anatomical target; ICHI does not have a body-system-agnostic code for this modality combination.
363680008 (Radiographic imaging procedure)(not mapped)ICHI contains many body-site-specific X-ray codes but no single overarching code representing "radiographic imaging procedure" as a generic supertype category.
4613005 (Radioimmunoassay)(not mapped)ICHI's laboratory block contains only specific named tests and does not include a generic radioimmunoassay technique code; no code in ICHI represents the analytical method as a class.
241400003 (Radiolabeled insulin study)(not mapped)This is a highly specialized investigative procedure using radiolabeled insulin to assess insulin receptor binding or pharmacokinetics, and ICHI contains no radioisotope study codes in the pancreatic/endocrine domain and no equivalent functional imaging study for insulin. No reasonable ICHI mapping exists.
16278002 (Radiologic supervision and interpretation of procedure)(not mapped)ICHI does not have a code representing the administrative/professional act of supervising and interpreting a radiologic procedure — its imaging codes each capture a specific modality applied to a specific body target, not the overarching supervisory/interpretive role. No ICHI code comes close to this meta-level SNOMED concept, and assigning any single imaging code would be misleading.
169396008 (Radiomimetic chemotherapy)(not mapped)ICHI does not contain codes for chemotherapy agents or routes specific enough to capture "radiomimetic" (DNA-crosslinking) chemotherapy; the closest generic pharmacotherapy administration codes (e.g., PZA.DB.AZ) are far too broad and would misrepresent the clinical specificity of this SNOMED concept.
303869002 (Radionuclide female genital system study)(not mapped)ICHI contains no nuclear imaging code for the female genital system; the available female genital imaging codes under NMS are limited to X-ray and ultrasound modalities only, and there is no GI-equivalent NEC nuclear imaging category for reproductive organs. No reasonable mapping exists without substantial semantic distortion.
8693001 (Radionuclide identification of eye tumor)(not mapped)ICHI contains no nuclear/radionuclide imaging code for the eye or any ocular structure — orbit imaging codes exist only for X-ray, CT, MRI, and ultrasound — and no residual eye or visual system nuclear imaging category exists to serve as an approximate mapping.
711272005 (Radionuclide scan of neuroendocrine function)(not mapped)ICHI has no code targeting the neuroendocrine system as a functional or anatomical entity for nuclear imaging; organ-specific codes (e.g., adrenal, pituitary) do not capture the systemic neuroendocrine function scan (e.g., somatostatin receptor scintigraphy / OctreoScan) that this SNOMED concept describes. The whole-body radioisotope scan (PZA.BA.BE) would lose the neuroendocrine functional specificity entirely.
710313004 (Radionuclide scan of peritoneal cavity)(not mapped)The ICHI imaging block for peritoneum and peritoneal cavity (BlockL5-KMA) includes X-ray, CT, MRI, and ultrasound but contains no nuclear/radioisotope scan code for the peritoneal cavity; no equivalent code exists elsewhere in the classification for this specific procedure.
399315003 (Radionuclide therapy)(not mapped)ICHI contains only site-specific radiotherapy codes (e.g., radioactive iodine ablation of thyroid, external beam radiotherapy by organ) and has no general category for systemic or unsealed-source radionuclide therapy as a standalone intervention class; no adequate mapping exists.
303868005 (Radionuclide urinary bladder studies)(not mapped)ICHI has nuclear imaging codes for the kidney (NAA.BA.BE) and whole body (PZA.BA.BE), but no nuclear/radioisotope imaging code exists specifically for the urinary bladder — the bladder imaging block only contains X-ray, MRI, and ultrasound codes. No reasonable ICHI equivalent is available.
168524008 (Radiotherapy - intraoperative control)(not mapped)ICHI's radiotherapy codes are all coded as destruction-by-radiotherapy at specific anatomical sites (e.g., NAI.GA.BA, LAA.GA.BA) and do not have any concept encoding the delivery modality of intraoperative radiotherapy or a cross-site intraoperative radiotherapy control concept; no reasonable match exists.
169356006 (Radiotherapy by infusion of organ cavity)(not mapped)ICHI has no code for intracavitary radiotherapy by infusion as a generic organ-cavity procedure. The radiotherapy codes in ICHI are all site-specific (e.g., bladder, uterus, prostate) and none capture the concept of radioactive fluid infusion into an unspecified organ cavity.
1217123003 (Radiotherapy course of treatment)(not mapped)ICHI has no code representing a generic radiotherapy course of treatment as an administrative or temporal concept; all ICHI radiotherapy codes are body-site-specific or whole-body (PZA.GA.BA), and none model the notion of a multi-session treatment course independent of target.
168526005 (Radiotherapy for analgesia)(not mapped)No ICHI code exists for radiotherapy applied specifically for pain relief; the ICHI pain interventions block (AXA) covers pharmacotherapy, physical modalities, and psychological approaches but does not include radiation-based analgesia, and the existing radiotherapy codes are defined by anatomical target rather than therapeutic intent.
168527001 (Radiotherapy for inflammation)(not mapped)ICHI radiotherapy codes are organised by anatomical target site (e.g., destruction of lesion of prostate by radiotherapy) with no axis or modifier for clinical intent such as treating inflammation versus malignancy. There is no code, extension, or block in ICHI that represents radiotherapy qualified by an anti-inflammatory purpose.
1344958001 (Radiotherapy for palliation of neoplasm)(not mapped)ICHI does not encode clinical intent (palliative vs. curative) as a dimension of its radiotherapy codes; all site-specific radiotherapy codes describe destruction of lesion or tissue at a given anatomical location regardless of therapeutic goal. No ICHI code or extension captures palliation of neoplasm as a concept distinct from other radiotherapy.
228704009 (Radiotherapy planning using a free set up)(not mapped)ICHI has no codes for radiotherapy treatment planning activities; the classification captures the delivery of radiotherapy itself (destruction by radiotherapy at a named site) but not the pre-treatment planning workflow or patient positioning methodology such as free set-up versus immobilisation.
228705005 (Radiotherapy planning using a simulator)(not mapped)No ICHI code exists for radiotherapy simulation or any radiotherapy planning methodology; ICHI encodes the therapeutic intervention itself (delivery of radiotherapy to a body part) and does not represent the pre-treatment simulation or planning process as a distinct classifiable act.
228708007 (Radiotherapy planning using diagnostic radiology)(not mapped)ICHI does not classify radiotherapy planning, nor planning that incorporates diagnostic imaging modalities such as CT or MRI; imaging codes in ICHI represent standalone diagnostic imaging acts and are not combinable in ICHI with a planning intent specific to radiotherapy delivery.
879915007 (Radiotherapy to bone)(not mapped)ICHI has no dedicated code for radiotherapy to bone or skeletal tissue; the musculoskeletal blocks (MA–MC) contain no destruction-by-radiotherapy entries, and no other code covers bone irradiation without restricting it to a different tissue type.
168521000 (Radiotherapy to hematological system)(not mapped)ICHI contains no radiotherapy (GA.BA) code targeting the haematopoietic or haematological system as a whole; the haematological system function block (DTA) has no destruction/radiation intervention, and available radiation codes all target specific organs or lymph nodes rather than the system broadly.
428831001 (Radiotherapy to perineum)(not mapped)ICHI contains no radiotherapy/destruction-by-radiotherapy code targeting the perineum; the PAW (perineum) block only includes surgical, drainage, and repair interventions, and no other ICHI radiotherapy code covers this anatomical site.
711299007 (Radiotherapy to thorax)(not mapped)ICHI radiotherapy codes are restricted to specific organs or tissue types (brain, eye, lymph nodes, skin/trunk, breast, bladder, prostate, uterus, cervix) and none encompasses the thorax as a target region; no block-level radiotherapy code for the thorax exists either.
169369005 (Radiotherapy using temporary abdominal implant)(not mapped)ICHI has no assignable code for brachytherapy (temporary radioactive implant); "Brachytherapy seeds" appears in the ICHI data but without a usable code, and no other ICHI code captures the technique of temporary implant-based radiotherapy in the abdominal region.
233555005 (Random blood donation)(not mapped)ICHI contains "Screening blood donations" and "Transfusion of blood or blood products" (DIA.DG.AF), but neither covers the act of giving/collecting a random (unselected, walk-in) blood donation. No ICHI code represents the donation collection procedure itself for a non-directed donor.
1156943004 (Randomized clinical trial)(not mapped)ICHI does not classify research study designs or methodological frameworks such as randomized controlled trials; searches for "trial," "randomized," and "research" returned no relevant results, confirming this concept is outside ICHI's scope.
16298007 (Rate measurement)(not mapped)"Rate measurement" is an abstract, non-specific SNOMED concept applicable to any physiological or laboratory rate (heart rate, respiratory rate, flow rate, etc.); all ICHI measurement codes are anchored to a specific body system or target and no single generic rate measurement category exists in ICHI.
115340009 (Ratio measurement)(not mapped)"Ratio measurement" is an abstract concept representing any measurement expressed as a ratio; ICHI does not have a generic ratio measurement code, and all measurement entries in ICHI are tied to specific anatomical targets or physiological functions.
223481002 (Reassuring about a disorder)(not mapped)ICHI does not have a code for the act of reassuring a patient about a disorder in general; its counselling and advising codes are all tied to specific body functions or systems rather than the generic communication act of reassurance about a condition.
223477002 (Reassuring about activity)(not mapped)ICHI has no code for reassuring a patient about activity in general; VEB.PN.ZZ (Advising about physical activity behaviours) is limited to physical activity behaviour change interventions rather than the clinical communication act of reassurance.
223480001 (Reassuring about observations)(not mapped)ICHI has no action axis for "reassuring" as a distinct communicative act, and the target concept "observations" (as a clinical activity) does not correspond to any ICHI target axis — which is structured around body systems, functions, and environmental factors, not clinical documentation or monitoring activities.
223478007 (Reassuring about procedure)(not mapped)ICHI has no action for "reassuring" and no target corresponding to "a procedure" as a category of health intervention; the ICHI target axis covers body structures, functions, and environmental determinants, not clinical activities.
223479004 (Reassuring about therapy)(not mapped)While ICHI has UAC.PN.ZZ (Advising about medications), there is no ICHI target for "therapy" in general, and "reassuring" is semantically distinct from advising or counselling; no reasonable ICHI mapping exists.
384686000 (Reattachment of lower extremity)(not mapped)ICHI contains reattachment codes for specific lower extremity sub-parts (foot, toe, ankle, thigh muscle) but no code covering reattachment of the lower extremity as a whole (i.e., limb replantation at the leg or thigh level).
179987000 (Reattachment of upper extremity)(not mapped)ICHI contains reattachment codes for the hand (PMD.LB.AA) and finger (PME.LB.AA) but no code covering reattachment of the entire upper extremity (limb replantation at arm level).
229211000 (Rebound therapy)(not mapped)ICHI contains no code for trampoline-based or rebound therapy; the exercise-leading codes are tied to specific body-system functions rather than a named therapeutic modality and are too imprecise to constitute a meaningful mapping.
1237262009 (Receptor tyrosine-protein kinase erbB-2 inhibitor therapy)(not mapped)ICHI does not classify pharmacotherapy at the level of drug class or molecular target; no codes exist for HER2 inhibitors, tyrosine kinase inhibitors, or targeted/biological therapy. The generic PZA.DB.AZ is too broad.
223438000 (Recommendation to discontinue a procedure)(not mapped)No assignable ICHI category code exists for an act of recommending cessation of a clinical procedure; the term "Discontinuing" (XG9S58) exists in ICHI only as an extension modifier, not as a standalone category.
223449006 (Recommendation to inform someone)(not mapped)ICHI has no code representing a generic act of recommending that a patient tell or notify another person; while there are codes for advising or education about specific topics (e.g. UAC.PN.ZZ, VEF.PN.ZZ), none captures the meta-act of instructing someone to go and inform a third party. The concept sits outside ICHI's coverage of clinical interventions.
85392009 (Reconstitution of lyophilized culture)(not mapped)ICHI contains no code for laboratory microbiological procedures such as reconstituting a freeze-dried (lyophilized) culture; this is a laboratory bench technique outside the scope of ICHI intervention categories.
1201948000 (Reconstruction using bipedicled flap)(not mapped)ICHI codes are structured around a body-part target and do not encode reconstruction technique alone; no ICHI code exists for unspecified-site reconstruction using a bipedicled flap.
736739001 (Reconstruction using deltopectoral pedicle flap)(not mapped)ICHI does not encode reconstruction technique (deltopectoral pedicle flap) as a standalone procedure independent of a body-part target; no assignable ICHI code covers flap-technique-only reconstruction.
112988006 (Recovery room monitoring, anesthesia)(not mapped)ICHI does not contain a code for post-anaesthesia or recovery room monitoring as a distinct intervention; anaesthesia codes cover administration rather than post-procedural monitoring.
165498002 (Red blood cell enzyme test)(not mapped)ICHI does not contain a code for red blood cell enzyme testing (e.g., G6PD, pyruvate kinase); no broader "erythrocyte biochemical test" category exists.
431325008 (Reduction of corticosteroid dosage)(not mapped)ICHI has no code for tapering or reducing a medication dose; the UAC block covers advising and providing medications but has no action code for dosage adjustment.
416215007 (Regenerative injection therapy)(not mapped)No ICHI code captures prolotherapy/PRP/regenerative injection into musculoskeletal soft tissues; injection codes are organ-specific.
720582003 (Registration for online access to local general practice service)(not mapped)Administrative act of granting patient portal access; outside ICHI's scope (Telehealth block covers remote interventions, not registration).
243221009 (Rehydration therapy)(not mapped)ICHI has no rehydration therapy code in any form; the electrolyte/water balance block covers only assessment and education.
703884003 (Reiki)(not mapped)ICHI does not include Reiki or any energy-based/biofield complementary therapy.
3137001 (Reimplantation)(not mapped)ICHI has no generic reimplantation code; LB (Reattachment) action axis exists only for specific anatomical targets with no residual/unspecified code.
25713009 (Reinsertion of internal fixation device)(not mapped)ICHI does not contain a code for replacement or reinsertion of a generic internal fixation device; joint-replacement codes are too anatomically specific and no general "replacement of bone fixation device" exists.
386500001 (Religious exploitation prevention)(not mapped)ICHI contains no concept for religious exploitation or any spiritual/religious harm prevention; the violence-related behaviour blocks cover family/partner and community violence but not religious exploitation.
444616008 (Removal of antithromboembolic stockings)(not mapped)The only ICHI entry related to compression stockings is an unassignable category node with no 3-axis code, and describes application rather than removal; no ICHI code captures removal of antithromboembolic stockings.
233149009 (Removal of conduit)(not mapped)ICHI has codes for creation/replacement of conduits (cardiac, urinary) but no dedicated code for conduit removal as a standalone procedure; the SNOMED term is also ambiguous as to conduit type (cardiac, urinary, vascular).
609250001 (Removal of device from head)(not mapped)ICHI has no single "head NEC" device removal code — only anatomically specific codes (brain, skull, eye, ear, orbit, cranial nerve, etc.). The SNOMED concept is an administrative grouper with no equivalent ICHI code.
609251002 (Removal of device from neck)(not mapped)ICHI provides only specific neck-region structures (cervical spine, head/neck joint, thyroid field, head/neck skin, carotid artery, etc.) without a single catch-all for the neck as a whole.
609106005 (Removal of device from trunk)(not mapped)ICHI has no single "trunk NEC" device removal code; available codes cover specific trunk substructures (rib/sternum, thoracic spine, trunk skin, diaphragm, etc.).
90810007 (Removal of embolus of bovine graft)(not mapped)ICHI contains no codes for interventions specifically targeting a vascular graft (bovine or otherwise) and no thromboembolectomy codes covering bypass conduits or prosthetic/biological grafts.
713541000 (Removal of entire genital organ)(not mapped)ICHI organises genital organ excisions by specific organ (orchidectomy, hysterectomy, penectomy, vulvectomy) with no unspecified pan-genital target code; the SNOMED concept is a high-level grouper covering any entire genital organ regardless of sex.
54891009 (Removal of foreign body from cerebral meninges)(not mapped)The cerebral meninges block (AAC) contains codes for biopsy, drainage, excision, repair, and release of cortical adhesions, but no code for removal of a foreign body or internal device from the cerebral meninges exists in ICHI.
225165001 (Removal of leeches)(not mapped)ICHI has codes for therapeutic application of living organisms to skin but no code for removal of leeches after application.
225164002 (Removal of ligature)(not mapped)ICHI has no generic "removal of ligature" code; the only related suture-removal code is abdominal-wall-specific and cannot represent a body-site-unspecified ligature removal.
84347005 (Removal of skeletal muscle stimulator)(not mapped)ICHI contains no code for removing an implanted device from skeletal muscle; musculoskeletal blocks lack device removal categories and electrical stimulation codes describe applying stimulation rather than removing an implanted stimulator.
239706007 (Removal of strapping)(not mapped)ICHI has MZZ.DP.AH for application of proprioceptive strapping but no corresponding code for removal; strapping removal is a nursing/wound-care task with no ICHI category.
1230036005 (Removal of tube)(not mapped)"Removal of tube" is a generic, body-site-agnostic concept; ICHI tube-removal codes are dispersed across body-system-specific categories with no single catch-all code adequately capturing this.
170506006 (Remove potential infection source)(not mapped)This SNOMED concept describes a generic, context-dependent clinical action to eliminate infection risk; ICHI's infection control codes address population/environmental measures, not this specific clinical removal act.
1230028001 (Removing nail polish)(not mapped)ICHI contains surgical nail interventions (LBD/LBF) but no code for the cosmetic or pre-procedural act of removing nail polish, which falls outside ICHI's scope of health interventions.
103770006 (Renal vein renin stimulation panel)(not mapped)ICHI contains no codes for hormonal stimulation tests, renin assays, or targeted renal vein blood sampling panels; the closest concept (DIA.AH.XA "Specimen collection of blood") captures only the specimen collection step and omits the provocation, lateralisation, and analytic dimensions that define this procedure.
5545001 (Repair of carotid body)(not mapped)The carotid body is classified in ICHI as a paraganglion under the peripheral nervous system extension codes, and no dedicated intervention category for repair of the carotid body exists in the classification. No sufficiently close approximation found across carotid artery, head/neck vessel, or nerve blocks.
449639000 (Repair of defect of fascia of lower limb)(not mapped)ICHI's lower limb musculoskeletal blocks (thigh, lower leg, foot) do not include a repair code for fascia specifically — lower leg fascia codes only cover incision and division, and foot/toe codes focus on ligament repair.
49988001 (Repair of epididymis)(not mapped)ICHI does not contain a dedicated block or category for the epididymis as a surgical target — the male genital system hierarchy includes blocks for the prostate, spermatic cord, scrotum, testis, and penis but no epididymis-specific interventions.
238201008 (Repair of gluteal hernia)(not mapped)A gluteal hernia protrudes through the greater sciatic foramen in the gluteal/posterior pelvic region; ICHI contains no gluteal hernia code, and no existing code (abdominal wall, perineum, or otherwise) is anatomically close enough to constitute even an approximate mapping.
359975006 (Repair of hernia cul-de-sac)(not mapped)A cul-de-sac (pouch of Douglas) hernia is an internal pelvic hernia through the rectouterine pouch; ICHI contains no code for this specific entity and no sufficiently related topographical repair code exists to justify even an approximate mapping.
31331005 (Repair of parathyroid gland)(not mapped)The ICHI parathyroid block (BlockL5-EBB) contains only six codes covering biopsy, scan, partial excision, total excision, endoscopic excision, and transplant — repair of the parathyroid gland as a distinct procedure is absent from the classification.
1344913007 (Repair of persistent cloaca)(not mapped)ICHI contains no code or block for cloaca or cloacal malformation repair — the classification does not model this complex congenital anomaly correction, which simultaneously involves the rectum, vagina, and urethra sharing a common channel. No single ICHI code adequately captures this multi-structure reconstructive procedure.
439775005 (Repair of persistent cloaca with lengthening of vagina)(not mapped)As with the base cloaca repair, ICHI has no code for cloacal reconstruction, and neither does it have a vaginal lengthening code (NMH codes cover dilatation, reconstruction, and suspension but not lengthening as part of a cloacal repair). This procedure is too complex and anatomically specific to be captured by any available ICHI category.
66706000 (Repair of pituitary gland)(not mapped)The ICHI "Interventions on pituitary gland" block (BlockL5-EAA) contains 18 category codes covering biopsy, imaging, incision, excision, drainage, and device insertion, but no repair or reconstruction code exists for the pituitary gland. ICHI has no assignable code that represents surgical repair of the pituitary gland.
62927001 (Repair of sciatic hernia)(not mapped)ICHI's hernia codes are limited to inguinal (PAM), femoral (PAN), and umbilical (PAO) hernias; sciatic hernia is a rare pelvic-floor herniation with no corresponding ICHI category, and no sufficiently close NEC or residual code exists to serve as a meaningful map.
233912002 (Replacement of heart valve poppet, prosthetic)(not mapped)A poppet is the internal occluder component of a ball-and-cage mechanical prosthetic valve; ICHI has no code for replacing a sub-component of an already-implanted prosthetic valve and no code approaches this level of granularity within the heart valve section (BlockL4-HDE).
240941008 (Replacement of intraluminal device in vein)(not mapped)ICHI has no dedicated "replacement of intraluminal device in vein" code; the vein blocks (upper limb, lower limb, head/neck, abdominal) contain insertion and dilatation-with-device codes but no KA (replacement) action for veins. The SNOMED concept is also deliberately unspecified as to which vein, making any body-region-specific ICHI code an inadequate match.
304996008 (Replacement of periodontal flap with osseous surgery)(not mapped)ICHI has no codes covering periodontal surgery procedures; the oral cavity blocks (KAA–KAT) include interventions on gum (KAG) but none capture periodontal flap replacement combined with osseous surgery.
406224006 (Reproductive care)(not mapped)"Reproductive care" is a broad administrative/service category covering sexual health, fertility, pregnancy, and contraception; ICHI organises these across multiple disparate blocks (NUA, NUB, NUD, NUE, NUG, NUH) with no single assignable code or block that acts as an umbrella for all reproductive care.
408958003 (Reproductive care assessment)(not mapped)ICHI provides separate assessment codes for individual reproductive sub-domains (e.g., NUD.AA.ZZ for fertility assessment, NUE.AA.ZZ for pregnancy functions assessment) but no single overarching assessment code that spans all reproductive care.
408960001 (Reproductive care management)(not mapped)Like "Reproductive care assessment," reproductive care management as a unified concept spans fertility, pregnancy, sexual health, and related domains, none of which are aggregated under a single ICHI management code.
1366482008 (Request for document translation service in braille)(not mapped)ICHI contains codes for braille equipment and health service referrals, but no code exists for requesting or arranging document translation into braille; this administrative act falls outside ICHI's classification scope.
62258005 (Resection of diverticulum)(not mapped)ICHI does not contain a site-nonspecific "excision of diverticulum" code; excision codes are organised by organ (oesophagus, colon, bladder, etc.), and no single ICHI category captures the anatomically unspecified resection of a diverticulum.
225349005 (Respecting the client's privacy)(not mapped)This is a nursing ethics/care practice activity (respecting patient privacy) that does not correspond to any classifiable health intervention in ICHI; no code for privacy protection, dignity, or analogous person-centred care conduct exists in the classification.
737849002 (Respite care case management)(not mapped)ICHI does not contain a concept for respite care or the coordination/management of temporary relief care for caregivers; neither the health-services environment blocks nor the activities/participation blocks contain anything representing respite care case management as a distinct health intervention.
229586001 (Rest, ice, compression and elevation treatment program)(not mapped)ICHI has no code representing the RICE protocol as a composite multimodal treatment program; individual components (cryotherapy, compression bandaging, elevation) are not enumerated as distinct interventions in ICHI, and no single ICHI code captures this bundled first-aid/conservative management approach.
104153004 (Reticulocyte count, flow cytometry)(not mapped)ICHI's essential laboratory test set does not include a reticulocyte count code; the closest candidates differ significantly in method and scope and would misrepresent this specific flow-cytometry-based enumeration of reticulocytes.
428739007 (Review of individual education plan)(not mapped)ICHI contains many "education about..." codes targeting body functions and health topics, but none represent reviewing or planning an individual education programme; this is an administrative/coordination act in a non-health-service domain that falls outside ICHI's coded scope.
172149008 (Revision of external orbital prosthesis)(not mapped)ICHI contains codes for intraorbital implants but has no code for fitting, adjusting, or revising an external (epithetic/facial) orbital prosthesis; no sufficiently close code exists in the classification.
179523005 (Revision of prosthetic interposition arthroplasty)(not mapped)ICHI contains no code for interposition arthroplasty (a technique where material is interposed between joint surfaces) at any joint, nor a joint-nonspecific revision of arthroplasty code. The joint-specific "Replacement of [joint] device" codes (KA.AA series) are anatomically too specific for this body-site-unspecified SNOMED concept, and none covers interposition arthroplasty as a distinct procedure type.
448972009 (Revision of prosthetic replacement of joint)(not mapped)ICHI provides joint-specific replacement of device codes (elbow, hip, shoulder, knee, etc.) but has no generic "joint, not elsewhere classified" replacement of device code that would capture the unspecified nature of this SNOMED concept. Selecting any single joint-specific code would impose an anatomical specificity not present in the source concept.
179765002 (Revision reattachment extra-articular ligament)(not mapped)ICHI has ligament reattachment codes only for specific named body sites (shoulder MDL.LB.AA, elbow MEL.LB.AA, wrist MFL.LB.AA, knee MML.MK.AA, etc.) with no body-site-unspecified or "not elsewhere classified" ligament reattachment category, and no code distinguishes extra-articular from intra-articular ligament. No reasonable single ICHI code captures this concept.
301046005 (Revision screw fixation of fracture without reduction)(not mapped)ICHI does not contain any codes for fracture fixation with internal hardware (screws, plates, nails); bone-related codes cover reduction, device implantation into specific bones, and fusion, but none encode screw-based osteosynthesis or fracture fixation as a procedure concept.
425152008 (Risk benefit ratio assessment)(not mapped)ICHI does not model risk-benefit ratio analysis as a classifiable health intervention; this is a clinical decision-making process with no corresponding ICHI code at either the category or block level.
386413005 (Risk identification)(not mapped)"Risk identification" as a standalone clinical act has no counterpart in ICHI, which does not classify generic risk appraisal processes independently of a specific body system, function, or behaviour target.
359805009 (RIST assay, direct)(not mapped)ICHI does not contain a code for radioimmunosorbent testing (RIST) or measurement of total serum IgE; the essential laboratory tests block covers a limited set of WHO priority tests and IgE quantification is absent. No reasonable approximate code exists within ICHI's scope.
359800004 (RIST assay, indirect)(not mapped)As with the direct RIST assay, ICHI contains no code for indirect radioimmunosorbent testing or any IgE-class immunoassay; the classification does not capture in-vitro allergy serology at this level of granularity.
1304313004 (Robotic radiotherapy)(not mapped)ICHI encodes radiotherapy only as site-specific destruction codes (e.g., LCA.GA.BA for breast) or total body irradiation (PZA.GA.BA), and has no generic cross-site radiotherapy category nor a robotic radiotherapy code; no single ICHI code adequately captures robotic radiotherapy as a modality-level concept independent of target site.
228585005 (Role play technique)(not mapped)ICHI has no code for role play as a specific therapeutic technique; the classification does not capture named psychotherapeutic or educational methods at this level of granularity, and the closest extension codes (XG0HN6 Cognitive skills and techniques, XG86J9 Emotional regulation skills and techniques) are extension/qualifier codes rather than assignable intervention codes representing this concept.
406921008 (Rosolic acid sodium salt stain method)(not mapped)Rosolic acid sodium salt (Aurin) staining is a highly specific histochemical staining technique for calcium detection in tissue sections; ICHI does not classify individual histological staining methods at this granularity, and unlike Romanowsky staining there is no parent examination code in ICHI that reliably represents this technique's typical clinical use context.
225245001 (Rubbing up a contraction)(not mapped)This obstetric maneuver (fundal massage to stimulate uterine contraction postpartum) has no corresponding ICHI code; ICHI contains no category for uterine fundal massage, manual uterine stimulation, or postpartum contraction management, and the closest uterine intervention codes (tamponade, repair, induction of labour) address categorically different actions.
406922001 (Saffron stain method)(not mapped)ICHI does not cover histological staining techniques or laboratory specimen preparation methods — these are analytic/laboratory procedures outside its scope. No searching via "stain", "histology", "microscopy", or fuzzy approaches yielded any relevant ICHI code.
395203006 (Sample viscosity)(not mapped)ICHI contains no codes for viscosity measurement, rheology, or fluid physical property assessment; exhaustive searches on "viscosity," "rheology," and fuzzy variants returned no relevant results. This laboratory measurement falls outside ICHI's current scope.
439252002 (Sampling of vulva for smear)(not mapped)The vulva interventions block (NMI) contains no specimen collection or smear-sampling code, and ICHI has no "specimen collection from vulva" category; the only analogous structure is vaginal specimen collection (NMH.AH.XF), which is a different anatomical target and cannot be used here.
405265004 (Satellite testing)(not mapped)"Satellite testing" refers to a laboratory service delivery model (decentralised/point-of-care testing performed close to the patient rather than in a central lab) — it describes where and how testing is organised, not a specific clinical intervention. ICHI does not classify healthcare service delivery models or testing site configurations, so no reasonable code exists.
252300007 (Schumm's test)(not mapped)Schumm's test is a highly specific colorimetric serum assay for methemalbumin used to detect intravascular hemolysis. ICHI contains no laboratory assessment codes for this test or its functional equivalents (haptoglobin, hemolysis markers), and the WHO essential laboratory test extension does not cover this specialized hematology test.
308535007 (Screening call)(not mapped)ICHI has no code representing a telephone-based screening contact; the "Interventions on screening behaviours" block (VDB) covers public health advocacy and education around screening uptake rather than a clinical screening call, and the telehealth extension codes (XG6UP2) are supplementary extension codes rather than standalone intervention codes. No ICHI category adequately captures the concept of an outbound or inbound telephone call for health screening purposes.
185540003 (Second patient "call")(not mapped)The SNOMED concept describes an administrative scheduling/recall activity (a second attempt to contact a patient), which is not a health intervention in the ICHI sense. No ICHI code — including the "health management encounter" residual codes under PZB — captures the notion of administratively calling a patient back; those codes represent face-to-face encounters, not contact attempts.
386417006 (Security enhancement)(not mapped)"Security enhancement" in SNOMED CT refers to a broad procedural concept of improving personal or environmental safety/security, which sits outside ICHI's scope for individual health interventions; ICHI's safety-related blocks (VC1, UEI) address specific behavioural or policy interventions and do not provide a code equivalent to a generic security-enhancement procedure.
89540006 (Segmental excision and ligation)(not mapped)"Segmental excision and ligation" is a compound procedure (partial excision combined with occlusion/ligation) applied without a specified anatomical site — ICHI requires a defined Target axis, and no single ICHI code combines both partial excision and occlusion/ligation actions on an unspecified vessel. The closest candidates each capture only one of the two actions and presuppose a specific body part.
64461008 (Seizure precautions)(not mapped)Seizure precautions is a nursing/safety protocol (padding side rails, removing hazards, keeping suction available) that does not correspond to any ICHI category; ICHI's safety-related behaviour codes address public health and behavioural interventions rather than acute clinical safety precautions for an individual patient, and no available code captures this concept with reasonable fidelity.
306560001 (Self-discharge)(not mapped)ICHI does not contain a code for patient self-discharge (i.e., a patient leaving a healthcare facility against medical advice or on their own volition). The only discharge-related ICHI code found, XG38D0 "Discharge planning," is a clinician-initiated care coordination activity and is semantically distinct from a patient-initiated self-discharge event.
11900001 (Semen analysis)(not mapped)ICHI does not contain a code for laboratory analysis of semen (spermogram/seminogram); the NGD block covers physical sperm-related interventions such as procurement and specimen collection, but not analytic examination of semen parameters.
274310001 (Sensory mapping)(not mapped)ICHI contains no code for sensory mapping (e.g., intraoperative or neurophysiological cortical sensory mapping); the closest candidates — somatosensory evoked potentials (AVC.AF.BP) or sensory function assessment (AV2.AA.ZZ) — capture related but semantically distinct procedures and none adequately represents the mapping concept.
68793005 (Serologic test)(not mapped)ICHI does not contain a generic "serologic test" category; its essential laboratory test section (BlockL1-XG1) only lists specific named assays (e.g., HIV antibody, dengue antigen), and there is no residual or general serology code to represent this broad SNOMED concept.
9954002 (Serologic test for rubella)(not mapped)ICHI's essential laboratory test block has no entry for rubella serology; despite extensive searching using "rubella," "virus antibody," "immunoassay," and browsing the full XG1 block, no rubella-specific or sufficiently related test code exists in ICHI.
391581001 (Serum dibucaine number)(not mapped)The dibucaine number is a highly specific biochemical test measuring percentage inhibition of pseudocholinesterase (butyrylcholinesterase) by dibucaine, used to detect atypical cholinesterase variants; ICHI contains no code for cholinesterase activity, enzyme inhibition assays, or pharmacogenetic testing, and no sufficiently related code exists to justify even a "relatedto" mapping.
313135006 (Serum P1 phenotype determination)(not mapped)P1 is a minor blood group antigen in the P1PK system, and its phenotype determination by serum testing has no corresponding code in ICHI; the closest available code (XG1NM8, A/B/O and Rhesus factor) covers only the main ABO/Rh blood grouping system and is too semantically distant to be used as a mapping.
225863005 (Shadowing)(not mapped)"Shadowing" in the clinical/healthcare context refers to a trainee following and observing a practitioner as a learning method; ICHI does not have a category for workforce development, experiential learning, or clinical observation of this type, and no searchable synonym (observation, supervision, mentoring, clinical training, learning) yielded a suitable match.
29923002 (Shaving)(not mapped)ICHI has no code for shaving as a procedure — whether as pre-operative surgical site hair removal, personal grooming, or another sense. The hygiene behaviours block (VED) covers advising or training about hygiene but not the physical act of shaving itself.
386432004 (Shock management)(not mapped)ICHI does not contain a generic "shock management" code; the concept covers a multimodal clinical bundle (fluid resuscitation, vasopressors, monitoring, CPR as needed) that spans multiple ICHI codes and cannot be adequately represented by any single ICHI category without significant information loss.
21837007 (Shortening of endopelvic fascia)(not mapped)ICHI has no code for interventions on the endopelvic fascia or pelvic connective tissue; no fascia plication or shortening code exists for the pelvic region.
385987000 (Sickness/injury care)(not mapped)This is a high-level category of curative/restorative clinical care for illness or injury with no counterpart in ICHI; ICHI does not classify general clinical encounters or undifferentiated curative care as a single intervention type.
410355000 (Sickness/injury care case management)(not mapped)ICHI contains no code for general illness/injury case management as an overarching service type; UEP-level codes address health system planning but not individual patient-level case management.
223413005 (Signs and symptoms education)(not mapped)ICHI's education codes are organised by specific body function or activity target, not by a cross-cutting concept like recognising signs and symptoms across all conditions; no single ICHI category captures generic signs-and-symptoms education.
406924000 (Sirius red F3B stain method)(not mapped)Sirius red F3B is a specific histochemical staining technique used to visualise collagen; ICHI does not classify individual laboratory staining methods or histochemical techniques at this level of granularity.
278745003 (Skew flap incision)(not mapped)A "skew flap incision" is a specific surgical incision technique used in amputation stump surgery; ICHI has no code for this named incision approach (flap codes in ICHI cover tissue flap types in reconstruction, not the incision technique).
737045009 (Skin traction care management)(not mapped)ICHI contains no code for skin traction (application/management of adhesive/surface traction devices to limbs, e.g., Buck's traction); closest candidates (PZX.LC.AH cast/splint application, PZX.KB.AH external immobilisation device replacement) are semantically distinct device types and do not represent ongoing nursing care management of skin traction.
113044007 (Smear for epithelial cells)(not mapped)A smear examination targeting epithelial cells is a generic cytological screening procedure distinct from cervical Pap smear; no ICHI code covers a non-site-specific epithelial cell smear.
359803002 (Solid phase labeled antigen competitive binding immunoassay)(not mapped)ICHI does not classify immunoassay techniques at the methodological level; its essential laboratory test codes represent specific analyte-based tests rather than assay formats.
359806005 (Solid phase sandwich immunometric noncompetitive immunoassay)(not mapped)ICHI does not represent immunoassay formats or techniques generically; the sandwich immunometric method has no corresponding ICHI code.
406925004 (Solochrome azurine (BS) stain method)(not mapped)ICHI contains no histochemical or special staining procedure codes; the classification does not cover laboratory staining techniques at any level of granularity.
406926003 (Solochrome black 6B stain method)(not mapped)ICHI lacks any codes for histological staining methods; this specialized dye-based staining technique falls entirely outside ICHI's scope.
406927007 (Solochrome cyanine R stain method)(not mapped)ICHI does not cover laboratory staining techniques or histochemical methods at any level of granularity; no ICHI block addresses specimen staining protocols as health interventions.
406928002 (Solochrome dark blue stain method)(not mapped)ICHI contains no representation of dye-based or chromogenic staining methods applied to tissue specimens; this highly specific laboratory technique falls outside ICHI's scope.
406929005 (Soluble berlin blue stain method)(not mapped)Berlin blue (Prussian blue) staining is an iron-detection histochemical technique; ICHI has no staining, histochemical, or iron-detection procedure codes.
6177004 (Southern blot assay)(not mapped)Southern blot is a molecular biology technique for DNA hybridization with no direct or approximate equivalent in ICHI; the closest genetic/nucleic acid codes target entirely different procedures.
24512008 (Special chemical test, explain by report)(not mapped)This is a highly administrative term for an unspecified chemical laboratory test with explanatory report; ICHI has no equivalent for a generic "chemical test" at this level of administrative abstraction.
70789004 (Special cytopathology procedure, explain by report)(not mapped)ICHI contains no code for cytopathology as a diagnostic discipline or for reporting cytopathological findings; the classification focuses on clinical interventions rather than laboratory interpretive activities.
9728002 (Special dosimetry, microdosimetry)(not mapped)ICHI contains no codes for dosimetry as a clinical measurement procedure; the classification does not cover radiation physics measurement services such as microdosimetry.
49097004 (Special dosimetry, TLD)(not mapped)Thermoluminescent dosimetry is a radiation physics measurement technique for personal/environmental dose monitoring; ICHI has no dosimetry codes, and the UBR (radiation) block covers only population/public-health interventions.
69285004 (Specific gravity measurement)(not mapped)ICHI contains no code for specific gravity measurement; the closest candidates (XG0NB5 Urine chemistry, XG4F04 Urinalysis test strips) are extension/ancillary codes describing the nature of a test rather than the act of measuring specific gravity, and neither captures this specific measurement concept.
4064007 (Specimen aliquoting)(not mapped)ICHI scope covers specimen collection (action axis AH, block PZX) but does not extend to pre-analytical laboratory handling activities such as dividing a specimen into aliquots; no matching or closely related code exists.
385832000 (Specimen care management)(not mapped)ICHI addresses specimen collection at various body sites but does not classify post-collection specimen care or management activities as a distinct intervention; no plausible match exists for this administrative-logistical concept.
73373003 (Specimen centrifugation)(not mapped)ICHI contains no code representing centrifugation or any specimen processing/preparation step; ICHI's specimen collection codes cover the act of collecting a specimen from the patient but not the subsequent laboratory technique of spinning a sample.
58063005 (Specimen collection education)(not mapped)ICHI's education codes (PM action axis) cover education about body functions, conditions, and health topics, but there is no code for education about specimen collection procedures or laboratory procedures.
734227007 (Specimen decontamination)(not mapped)ICHI's decontamination codes (VL action axis) are exclusively environmental remediation interventions (air, water, soil) and do not cover decontamination of biological specimens as a pre-analytical laboratory step.
90621001 (Specimen dispatch and referral, complex)(not mapped)ICHI does not contain any code representing the transport or dispatch of specimens between sites or laboratories; UEP.TI.ZZ (Referral to health provider) addresses referral of persons, not specimens, and is therefore not a suitable match.
27872000 (Specimen freezing)(not mapped)ICHI contains no codes for preservation or cryogenic storage of biological specimens; the cooling codes present (PZA.SE.ZZ, PZX.SE.ZZ) refer to therapeutic cooling of body temperature in patients, not laboratory specimen freezing.
69997009 (Specimen refrigeration)(not mapped)As with specimen freezing, ICHI has no codes covering cold storage or refrigeration of specimens; pre-analytical specimen preservation steps fall outside the scope of ICHI, which classifies health interventions delivered to persons, populations, or environments.
103762001 (Specimen volume measurement)(not mapped)ICHI does not have a code for measuring the volume of a collected specimen; ICHI's specimen collection codes cover the act of collecting samples, not post-collection quantitative measurement.
103763006 (Specimen volume measurement for timed urine collection)(not mapped)A more specific variant of specimen volume measurement applied to a timed urine collection protocol; ICHI contains no codes for volumetric quantification of collected specimens and no timed-collection concept.
169278002 (Spectrometry)(not mapped)Spectrometry is an analytical laboratory technique that falls outside the scope of ICHI's health intervention classification; ICHI contains no codes for instrumental analytical chemistry methods such as mass spectrometry or spectrophotometry.
287223009 (Spinal cord exploration)(not mapped)The ICHI spinal cord block (BlockL5-ABA) contains no exploration or inspection category, and no broader ICHI block exists that captures surgical exploration of the spinal cord as a standalone coded intervention.
252933005 (Split ejaculation examination)(not mapped)ICHI has no code for split ejaculate analysis (an andrology lab procedure examining separately collected ejaculate fractions); the closest structural codes (NGD.AH.XE specimen collection of sperm; NUD.AA.ZZ assessment of fertility functions) do not capture the analytical examination nature of the SNOMED concept.
406932008 (Spore stain method)(not mapped)ICHI does not classify laboratory staining techniques or microbiological identification methods as distinct interventions; no histology or microbiology staining procedure codes exist that could serve as even an approximate match.
72336006 (Spot test)(not mapped)"Spot test" is a generic point-of-care qualitative screening test concept with no corresponding term, synonym, or structural equivalent in ICHI; ICHI does not catalogue generic procedural categories at this level for bedside/rapid diagnostic tests.
117032008 (Spun specimen)(not mapped)ICHI covers specimen collection but does not represent specimen processing/preparation steps such as centrifugation; "spun specimen" describes a laboratory pre-analytical handling technique outside ICHI's scope.
433457002 (Steam heating of tissue specimen)(not mapped)Steam heating of a tissue specimen is a histopathology laboratory pre-analytical processing step (heat-induced epitope retrieval) used in immunohistochemistry; this falls outside ICHI's scope of health interventions performed on patients and has no corresponding code.
448461009 (Stereotactic radiation therapy using megavoltage radiation)(not mapped)ICHI encodes radiotherapy by target organ and has no target-agnostic radiotherapy codes; this SNOMED concept describes a technique and beam type without specifying a target body part, making it impossible to assign a single ICHI category code.
115959002 (Stereotactic radiosurgery)(not mapped)ICHI structures all radiotherapy/radiosurgery codes around a specific target organ, and this SNOMED concept is a technique-level category with no target specified; no single ICHI code covers stereotactic radiosurgery as a modality-only concept without a body-part target.
87221008 (Sterility testing)(not mapped)Sterility testing is a laboratory quality-assurance procedure performed on pharmaceutical products, medical devices, or culture media to confirm absence of viable microorganisms; ICHI contains no code for this procedure as it falls outside the scope of clinical interventions.
409684001 (Sterilization of equipment)(not mapped)Sterilization of medical/surgical equipment (autoclaving, ETO, etc.) is a healthcare support/decontamination process; ICHI's decontamination codes address environmental remediation of outdoor/indoor spaces and water, not instrument reprocessing, and no code for equipment sterilization exists.
699040006 (Stool monitoring)(not mapped)ICHI contains no code for monitoring of stool/faecal output or bowel function — the monitoring codes present cover haemodynamic, neurological, respiratory, and obstetric parameters, with no equivalent for observing or tracking stool characteristics or frequency.
113034005 (Streptokinase antibody measurement)(not mapped)ICHI does not include laboratory serology tests for streptokinase antibodies; the essential laboratory tests block (XG1) covers only a limited set of priority tests (HIV, hepatitis, malaria, etc.) and contains no entry for streptokinase or related antibody assays.
304639001 (Stress mapping)(not mapped)"Stress mapping" refers to cardiac electrophysiological stress mapping, but no ICHI code covers this specific procedure; the only "Mapping" code found is a means axis value rather than a standalone procedure, and no cardiac mapping concept exists in ICHI.
185780005 (Stress monitoring first letter)(not mapped)This is an administrative act — sending a first invitation letter to a patient for a stress monitoring clinic appointment. ICHI does not classify administrative patient correspondence or appointment invitations.
185781009 (Stress monitoring second letter)(not mapped)Like the first letter, this represents a follow-up administrative invitation letter for a stress monitoring clinic appointment. ICHI has no scope for patient recall or administrative correspondence of this nature.
185784001 (Stress monitoring telephone invite)(not mapped)This is a telephone-based administrative invitation to attend a stress monitoring clinic, which is purely a scheduling/administrative act. ICHI does not include patient appointment reminder or invitation activities.
185782002 (Stress monitoring third letter)(not mapped)This SNOMED concept is a UK primary care administrative call-recall action — sending a third invitation letter to a patient for a stress monitoring programme — which is an administrative workflow event, not a health intervention classifiable in ICHI.
185783007 (Stress monitoring verbal invite)(not mapped)This concept represents a UK primary care administrative action — verbally inviting a patient to attend a stress monitoring appointment — rather than a clinical health intervention. ICHI does not classify call-recall administrative activities.
300036000 (Subcutaneous infusion)(not mapped)ICHI contains no code for subcutaneous (hypodermic) infusion or hypodermoclysis; injection and infusion codes are either organ-specific or route-specific and none represent the percutaneous subcutaneous fluid delivery route as a standalone intervention.
1335764006 (Subcutaneous injection of carbon dioxide)(not mapped)ICHI has no code for carboxytherapy or subcutaneous gas injection; subcutaneous injection codes do not exist as a general category in ICHI, and no substance-specific code for carbon dioxide injection is present anywhere in the classification.
104150001 (Sucrose hemolysis test)(not mapped)The sucrose hemolysis (Ham) test is a specialized diagnostic test for paroxysmal nocturnal hemoglobinuria; ICHI's essential laboratory test extension block does not include this test, and no broader ICHI category adequately captures this specific haematological diagnostic assay.
121346008 (Sulfonyluric hypoglycemic identification)(not mapped)Sulfonylurea identification is an analytical/toxicological laboratory procedure, and ICHI's Essential Laboratory Tests extension block contains no code for drug class identification or therapeutic drug monitoring of oral hypoglycemics.
406937002 (Sunset yellow FCF stain method)(not mapped)ICHI does not contain histological or histochemical staining methods as procedural codes. Candidate extension codes such as XG30Q5 and XG69Q0 are too broad and belong to the laboratory extension chapter rather than the assignable intervention classification.
233475003 (Superficialization of vessel for vascular access)(not mapped)Superficialization — surgically relocating a deep vessel to a subcutaneous position for dialysis access — has no corresponding ICHI code. Exploration of vein, blood vessel reconstruction, and arteriovenous shunt management codes do not capture this specific operative technique.
704074005 (Supervision when away from usual care setting)(not mapped)ICHI contains no concept for supervising a person when they are outside a usual care environment; the closest ICHI concepts pertain to specific body functions or activities rather than the setting-agnostic supervisory act described by this SNOMED concept.
223492001 (Supervision while performing activity)(not mapped)ICHI has no generic supervision during activity category; its activity-related codes address specific actions such as observing, training, or providing practical support for named activities, none of which captures the generic supervisory act.
304579001 (Supervision while performing procedure)(not mapped)ICHI does not model procedural supervision (e.g., a clinician overseeing another clinician or trainee carrying out a procedure) as a classifiable intervention; this is an administrative/educational role concept rather than a direct health intervention on a patient.
410421002 (Support group surveillance)(not mapped)ICHI has no concept representing surveillance or monitoring of a support group as an organisational entity. Surveillance codes in ICHI are framed as population public health surveillance of behaviours or environmental factors, not oversight of therapeutic groups.
285784000 (Suppression treatment)(not mapped)"Suppression treatment" is a high-level SNOMED grouper concept encompassing diverse treatments aimed at suppressing a pathological process (e.g., hormonal, immune, or tumour suppression), and no ICHI code captures this abstract category; the available pharmacotherapy codes in ICHI are specific to route of administration or drug type rather than the therapeutic goal of suppression.
117031001 (Supravital stain method)(not mapped)ICHI does not represent laboratory staining techniques or reagent-based methods as classifiable interventions; the concept describes a histological/haematological technique (e.g., new methylene blue for reticulocytes) with no corresponding ICHI category, even under the Essential Laboratory Tests extension block.
239366007 (Surgery on study models of jaws)(not mapped)This SNOMED concept describes pre-surgical simulation performed on plaster dental casts of the jaws rather than on a patient, and ICHI has no classification for in-vitro or model-based surgical planning procedures; the nearest patient-facing jaw surgery codes (mandibular/maxillary osteotomy) describe actual bone interventions and are semantically distinct.
386454002 (Surgical assistance)(not mapped)ICHI classifies health interventions by target, action, and means, and has no category representing the role of a clinician providing surgical assistance to another practitioner; this concept is a workforce/administrative role rather than a discrete patient-directed intervention.
165130003 (Surgical biopsy not taken)(not mapped)ICHI classifies health interventions that were performed; it contains no concept for a procedure that was planned but not carried out or declined. This SNOMED concept represents a clinical negation/absence record, which falls entirely outside the scope of ICHI coding.
287540001 (Surgical biopsy of male genital structure)(not mapped)ICHI does not have a single code covering biopsy of the male genital system as a whole; biopsies are coded at individual organ level (prostate, testis, penis, scrotum, spermatic cord), and no "not elsewhere classified" biopsy code exists for the male genital system collectively. The organizational block BlockL4-NGA (Interventions on male genital system) is non-assignable, and no single assignable code adequately represents this undifferentiated concept.
165129008 (Surgical biopsy taken)(not mapped)This SNOMED concept is a generic, site-unspecified record of a surgical biopsy having been performed; ICHI organises all biopsies by specific anatomical target and has no site-agnostic "biopsy performed" code, so no reasonable single ICHI code can represent the breadth of this concept.
47585001 (Surgical closure of anastomosis)(not mapped)ICHI contains codes for creating anastomoses (LB action) and for closing specific stomas or fistulas, but has no code representing the surgical closure (takedown) of a pre-existing anastomosis as a general, site-unspecified procedure; the closest candidates (stoma closures, fistula closures) refer to different specific constructs.
25852009 (Surgical closure of pouch)(not mapped)ICHI has no generic "closure of pouch" code; specific stoma closures (gastrostomy, enterostomy) exist but "pouch" is anatomy-neutral and could refer to pharyngeal, rectal, or other structures. No sufficiently close or parent-level code covers this concept without unacceptable loss of precision.
85089003 (Surgical closure of shunt)(not mapped)ICHI contains codes only for creation of shunts (ventricular, pleuroperitoneal, arteriovenous, cavopulmonary, etc.) but has no codes for shunt closure, takedown, or removal. The concept has no viable ICHI equivalent.
363317007 (Surgical manipulation procedure)(not mapped)This SNOMED concept is a high-level grouper for all surgical manipulation procedures; ICHI has no equivalent non-site-specific, non-approach-specific manipulation category — individual ICHI manipulation codes are all bound to specific body targets, and the PA axis value is not an assignable clinical code.
50322008 (Surgical pathology specimen, clerical procedure including coding of diagnoses)(not mapped)This SNOMED concept describes an administrative clerical act of coding diagnoses from a pathology specimen, which falls entirely outside ICHI's scope of clinical health interventions; no corresponding ICHI code exists.
389269000 (Surgical precautions)(not mapped)"Surgical precautions" is a perioperative safety management concept (aseptic technique, patient safety measures) for which ICHI has no dedicated category; the available ICHI codes in the health-services domain address policy-level infection control or public health measures rather than intraoperative procedural precautions.
42729000 (Surveillance culture)(not mapped)ICHI does not include a code for microbiological surveillance culture (i.e., obtaining and incubating a specimen to screen for colonisation by organisms such as MRSA); specimen collection codes exist but are site-specific, and no culture/incubation or epidemiological screening concept is present in ICHI.
225418004 (Surveillance of condition)(not mapped)ICHI's surveillance codes are exclusively in the public-health/environmental domain (U-block, VC action axis) and do not cover clinical surveillance of an individual patient's condition; no individual-level "monitoring of a health condition" category corresponds to this generic SNOMED concept.
702636002 (Surveillance of contraception)(not mapped)ICHI contains no code for monitoring or surveillance of contraceptive use or method effectiveness; the reproductive/fertility function block (NUD) covers assessment and counselling of fertility functions but not contraception surveillance, and no public-health surveillance code for contraception exists in the U-block.
386457009 (Surveillance: remote electronic)(not mapped)ICHI has no generic code for remote electronic patient monitoring or telemonitoring; the closest candidates (e.g., AAA.AI.BL — video/radio-telemetered EEG monitoring) are narrowly scoped to specific physiological targets and do not represent the general concept of remote electronic surveillance of a patient's health status.
56275003 (Suture ligation)(not mapped)"Suture ligation" is a technique/means concept — the act of tying off a structure with a suture — rather than a procedure on a specific anatomical target; ICHI organises codes by target+action+means and has no generic technique-level code for suture ligation independent of an anatomical target.
71539001 (Suture of fascia)(not mapped)ICHI has repair codes for fascia at specific body-region blocks (e.g., hand/finger, knee, shoulder) but no generic, body-site-unspecified "suture/repair of fascia" code. The SNOMED concept is non-site-specific and has no corresponding ICHI category.
79003003 (Suture of ligament)(not mapped)ICHI has no generic site-unspecified ligament repair code; all ligament repair codes are tied to a specific anatomical site (knee, hand, wrist, shoulder, etc.), so there is no code that captures a body-site-agnostic "suture of ligament" as modelled in this SNOMED concept.
1217447004 (Suture of periosteum of carpal bone)(not mapped)ICHI bone blocks for the forearm (MFB) and hand (MGB) contain no periosteum-specific repair or suture codes; the periosteum as a distinct tissue target is not represented as an action target in ICHI's musculoskeletal classification, leaving no reasonable equivalent code.
1217446008 (Suture of periosteum of metacarpal bone)(not mapped)As with carpal periosteum, ICHI's hand/finger bone block (MGB) does not include periosteum-specific repair codes; this level of anatomical and tissue specificity (periosteum of a named hand bone) has no corresponding ICHI category.
278744004 (Symmetrical flap incision)(not mapped)ICHI codes incisions by anatomical target (e.g., incision of skin by body region) but has no concept of incision geometry or approach type such as a "symmetrical flap"; this is a surgical planning/technique descriptor that does not map to any assignable ICHI category.
121347004 (Sympathomimetic identification)(not mapped)This SNOMED concept describes laboratory identification of a sympathomimetic substance (toxicology/drug identification), which has no corresponding entry in ICHI's essential laboratory tests extension block or elsewhere in the classification.
225353007 (Symptom control)(not mapped)ICHI does not contain a generic "symptom control" or "palliative care management" concept — extensive searches across symptom, control, palliative, supportive care, and pain management returned no relevant procedural matches. This is a high-level care-intent category with no corresponding code in ICHI's intervention structure.
408283008 (T cell diagnostic panel test)(not mapped)No ICHI code covers a T cell diagnostic panel (a laboratory immunophenotyping battery assessing T cell subsets); ICHI does not contain a direct equivalent for this type of clinical laboratory panel.
69132002 (T cell receptor gene rearrangement)(not mapped)T cell receptor gene rearrangement testing is a molecular diagnostic procedure (PCR or Southern blot for clonality assessment) for which there is no corresponding ICHI code; ICHI does not contain codes for molecular genetic or clonality assays at this level of specificity.
290037006 (Take ear impression)(not mapped)ICHI has no code for taking an ear canal impression (a preparatory step for hearing aid or ear mould fabrication). The ear intervention blocks contain only surgical, diagnostic, and functional codes; hearing aid fitting preparation is not represented.
234760001 (Take impression for extraoral maxillofacial prosthesis)(not mapped)ICHI has no code covering extraoral maxillofacial prosthetics or impression taking for such devices; the dental codes in the KAE block are scoped to teeth and intraoral structures, and no broader maxillofacial prosthetics pathway provides a reasonable match.
87230000 (Take-down of anastomosis of intestine)(not mapped)ICHI contains codes for creating intestinal anastomoses (e.g., KZZ.LB.AA — Anastomosis of intestine, NEC) but has no procedure code representing the reversal or takedown of an existing intestinal anastomosis. The concept of dismantling a previously created anastomosis is not represented in the ICHI classification.
4626009 (Take-down of arterial anastomosis)(not mapped)ICHI contains codes for creating arterial anastomoses (e.g., IZA.LB.AA — Anastomosis of artery, NEC) but no code exists for the takedown or reversal of an arterial anastomosis. This specific surgical concept is absent from the ICHI classification.
233133007 (Take-down of Fontan operation)(not mapped)ICHI codes the forward Fontan-type procedures (HAB.LI.AA — Creation of a conduit between right atrium and pulmonary artery; HIC.LI.AA — Total cavopulmonary connection completion) but contains no code for the reversal or takedown of a Fontan circulation. This specific complex congenital cardiac revision procedure is not represented in ICHI.
13811001 (Take-down of gastric anastomosis)(not mapped)ICHI has codes for creating a gastric anastomosis (KBF.LB.AA — Gastric anastomosis; KBF.LB.AB — Laparoscopic gastric anastomosis) but no code for its reversal or takedown. The concept of surgically dismantling a pre-existing gastric anastomosis is not represented in the ICHI classification.
406938007 (Tartrazine stain method)(not mapped)Tartrazine staining is an in-vitro laboratory histological technique applied to tissue specimens, not a health intervention performed on a patient; ICHI does not classify laboratory analytical or staining methods and no suitable code exists.
80363007 (Tease mount preparation)(not mapped)Tease mount preparation is a specific histology laboratory technique (mechanically separating tissue fibres onto a slide for microscopic examination) that has no corresponding assignable ICHI category. ICHI's XG30Q5 Histopathology extension code exists but is not an assignable intervention category and is far too broad to constitute a meaningful mapping.
879784008 (Telehealth rehabilitation monitoring)(not mapped)ICHI's telehealth codes are extension codes designed to modify other intervention codes rather than function as standalone assignable categories; there is no single assignable ICHI category code that captures remote monitoring of rehabilitation progress via telehealth. A full representation would require combining a rehabilitation monitoring code with a telehealth extension, which is beyond a single-code mapping.
275607008 (Temporary resident registration)(not mapped)"Temporary resident registration" is an administrative/bureaucratic act of recording a patient's temporary residency status, which falls entirely outside ICHI's scope. ICHI covers clinical, rehabilitative, and public health interventions, but not patient registration or administrative enrollment processes.
43222004 (Test kit method)(not mapped)"Test kit method" is a highly generic methodological descriptor (a technique modifier) rather than a specific health intervention; ICHI classifies health interventions by target body system and action, so there is no corresponding concept in ICHI for a laboratory method type used across many different tests.
85825007 (Therapeutic application of vasopneumatic device)(not mapped)Extensive searching across compression therapy, mechanical/physical therapy, rehabilitation, circulatory support, and device application terms found no ICHI code for intermittent pneumatic compression (vasopneumatic device) used therapeutically for conditions such as lymphoedema or DVT prophylaxis; this specific intervention has no reasonable match in the current ICHI classification.
274425002 (Therapeutic aspiration of cyst)(not mapped)ICHI contains only site-specific cyst drainage codes (e.g. femoral bone cyst, tibial bone cyst) with no generic "aspiration of cyst" category applicable across all body sites, and the SNOMED concept is itself a cross-site grouper with no meaningful single ICHI equivalent.
61259000 (Therapeutic electrical stimulation for bone healing)(not mapped)Although ICHI references "Bone growth stimulator invasive" as a concept, it carries no assignable category code in the classification, and no other ICHI code adequately represents electrical stimulation specifically applied for bone healing/fracture repair.
61109003 (Therapeutic radiology port film interpretation and verification)(not mapped)ICHI contains no code for radiotherapy portal imaging, treatment field verification, or port film interpretation; all radiotherapy-related codes in ICHI represent the delivery of radiation for tissue destruction (e.g. GA.BA action codes) or total body irradiation, not the planning, quality assurance, or dosimetric verification activities that this SNOMED concept describes.
43802008 (Thermocauterization)(not mapped)ICHI has no assignable code representing thermocauterization (heat-based tissue destruction/cautery) as a generic or site-unspecified procedure; the GA (destruction) action exists only within body-site-specific category codes, and no means code for thermal cautery without a specified target is present in the classification.
40538005 (Thermography)(not mapped)ICHI contains no code for thermography (infrared thermal imaging) as a diagnostic modality; the imaging section is organised by body region and modality (X-ray, CT, MRI, ultrasound, angiography) without any entry for thermal/infrared imaging.
25306006 (Thermography of deep vein)(not mapped)As with thermography in general, ICHI contains no thermography or infrared imaging modality codes; the vein-of-lower-limb imaging block includes only angiography, CT, MRI, and ultrasound. No ICHI code covers thermal imaging of the venous system.
252237004 (Thiamine pyrophosphate enhancement test)(not mapped)No ICHI code exists for the TPP enhancement test (erythrocyte transketolase assay for thiamine/vitamin B1 deficiency); the essential laboratory tests block contains no vitamin or enzyme-activity measurement codes.
406939004 (Thioflavine T stain method)(not mapped)ICHI contains no histochemical or histological staining concepts; laboratory staining methods are outside ICHI's scope, which focuses on clinical health interventions rather than bench-level diagnostic techniques.
406940002 (Thionine stain method)(not mapped)As with Thioflavine T, ICHI does not classify individual histological staining methods such as Nissl/thionine staining; bench laboratory techniques of this specificity are not represented in the classification.
185541004 (Third patient call)(not mapped)ICHI has no concept corresponding to a numbered patient call or follow-up contact event; this SNOMED concept is a primary care administrative sequencing code with no ICHI equivalent.
120147004 (Thorax excision)(not mapped)"Thorax excision" is a broad SNOMED grouper concept spanning excision of any thoracic structure (lung, pleura, rib, sternum, mediastinum, heart, etc.), and no single ICHI assignable code or block covers excision across the entire thorax as a unified concept; the closest ICHI codes are organ-specific and would only apply to the specific sub-procedure intended.
171182009 (Thyroid disorder screening)(not mapped)ICHI contains no code for thyroid-specific disorder screening; the screening behaviour block (VDB) covers screening behaviours in populations but not organ-specific clinical screening, and the endocrine block (EBA/ETK) lacks a screening category.
119946003 (Thyroid gland reconstruction)(not mapped)The ICHI thyroid block (BlockL5-EBA) contains no reconstruction code for the thyroid gland; reconstruction codes are present for cardiovascular structures but not for endocrine glands.
35650009 (Thyroid panel)(not mapped)ICHI does not classify biochemical laboratory test panels (TSH, T3, T4); laboratory diagnostic panels of this type fall outside the ICHI scope for interventional coding.
104972000 (Thyroid stimulating immunoglobulins measurement)(not mapped)ICHI has no code for measuring thyroid-stimulating immunoglobulins (TSI/TSAb); the closest laboratory test code (XG6YN3) is for TSH, a different analyte, so no reasonable match exists.
127792000 (Tilt tube coagulation time method)(not mapped)ICHI contains no codes for laboratory measurement methods or coagulation testing; the haematology codes present (e.g., DIA.AH.XA) address specimen collection only and are too dissimilar.
406941003 (Titan yellow stain method)(not mapped)Titan yellow is a highly specific histochemical stain for magnesium; no staining methods, histochemical techniques, or laboratory staining concepts are represented in ICHI.
183094000 (TLC - tender loving care)(not mapped)"Tender loving care" denotes a non-specific approach of compassionate supportive care rather than a defined clinical intervention; ICHI requires a specific action-target-means combination, and no category captures this informal concept.
38038000 (Tolerance test)(not mapped)"Tolerance test" is a broad, non-specific category encompassing challenge/provocation testing across many body systems and substances; ICHI has specific provocation tests but no single code covering the general parent concept of "tolerance test."
173352002 (Tongue and palate operations)(not mapped)This SNOMED concept is a high-level grouping combining operations on tongue and palate into a single heading; ICHI has separate blocks for tongue (BlockL5-KAB) and palate (BlockL5-KAS, BlockL5-KAT) interventions with no combined parent code.
119962009 (Tonsil repair)(not mapped)The tonsil block (BlockL5-DAA) contains biopsy, incision, excision, drainage, destruction, and tonsillectomy codes, but no repair code for the tonsil; no other ICHI section contains a tonsil repair code.
430854000 (Touch preparation of specimen)(not mapped)Touch preparation (imprint cytology) is a laboratory specimen handling technique in which a tissue specimen is pressed against a glass slide to transfer cells; ICHI does not classify specimen preparation methods as health interventions, and no code for imprint, touch prep, or analogous cytological preparation technique exists in ICHI.
48035000 (Traction maintenance)(not mapped)ICHI contains no code for the ongoing nursing/clinical activity of monitoring, adjusting, and maintaining skeletal or skin traction; the management-of-external-appliance codes that exist are all anatomically specific and none generalises to traction maintenance as a stand-alone procedure concept.
723688009 (Traditional Chinese Medicine)(not mapped)ICHI does not contain a code representing Traditional Chinese Medicine as a practice category; the closest codes (PZX.SP.AE acupuncture, PZX.SQ.AH moxibustion) represent individual TCM techniques rather than the overarching therapeutic system. The SNOMED concept is a broad classification of a healthcare paradigm, not a specific procedure, so no single ICHI code is a reasonable match.
789789009 (Traditional Māori medicine)(not mapped)ICHI contains no code for traditional Māori medicine or any indigenous medicine system; searches for "traditional", "indigenous", and "Maori" returned no results. As with TCM, this SNOMED concept represents a healthcare paradigm rather than a specific intervention, and no ICHI code captures it at any level of granularity.
28687005 (Transcatheter therapy by infusion with angiography)(not mapped)This SNOMED concept describes a composite interventional radiology procedure — catheter-directed arterial infusion (e.g., thrombolytics, chemotherapy) performed under angiographic guidance — and no single ICHI code captures this combination of infusion therapy with concurrent angiography across non-specified vascular targets.
397832002 (Transcranial cerebral oximetry)(not mapped)ICHI contains no code for cerebral oximetry or near-infrared spectroscopy of the brain; the brain monitoring block covers only electroencephalography and percutaneous monitoring, and no imaging or physiological measurement code covers transcranial oxygenation measurement.
253466006 (Transection of pedicle graft)(not mapped)Transection of a pedicle graft is a distinct surgical step (severing the vascular pedicle to fully detach a transferred flap after it has established its blood supply); ICHI contains codes for procurement and reconstruction using pedicle/flap tissue but no code representing the act of dividing or detaching a pedicle graft.
9698004 (Transfer of culture to holding media)(not mapped)This is a laboratory microbiology bench technique (subculturing to a transport or holding medium) that falls outside ICHI's scope; ICHI covers specimen collection but not downstream in-laboratory processing steps such as media inoculation or culture transfer.
52614004 (Transfer of digit to replace absent thumb, same hand)(not mapped)Pollicization is a complex composite procedure involving transposition of a finger with its bone, joints, tendons, nerves, and vessels to reconstruct an absent thumb; no single ICHI code covers this multi-structure reconstruction, and the available hand/finger codes (tendon transfer, bone graft, etc.) each capture only one component of the procedure.
19269007 (Transfixion)(not mapped)Transfixion (passage of a pin, wire, or suture through tissue to achieve fixation) has no corresponding ICHI code; ICHI fixation codes (action LC) are all organ- or structure-specific and do not represent the generic technique of transfixion as a standalone procedure concept.
33850009 (Transplantation of carotid body)(not mapped)The carotid body exists only as an ICHI extension/target entity, and no assignable intervention category for carotid body transplantation exists anywhere in the classification. This is an extremely rare, historically experimental procedure that ICHI does not classify.
68316003 (Transplantation of pineal gland)(not mapped)ICHI has a dedicated block for interventions on the pineal gland covering biopsy, excision, exploration, and incision, but no transplantation code exists. Pineal gland transplantation is not a recognised clinical procedure, and ICHI does not represent it.
38805005 (Transplantation of pituitary gland)(not mapped)ICHI has a dedicated block for interventions on the pituitary gland with codes covering biopsy, excision, imaging, and drainage, but no transplantation code exists. Pituitary gland transplantation has no corresponding ICHI assignable category.
75792002 (Transplantation of vitreous)(not mapped)The ICHI block for vitreous body contains only aspiration, injection, destruction, drainage, and vitrectomy codes — there is no transplantation of the vitreous code anywhere in the ICHI hierarchy. This SNOMED concept has no reasonable ICHI match.
46285006 (Transposition of abdominal tissue)(not mapped)ICHI has no code for transposition or repositioning of generic abdominal tissue; transposition codes in ICHI cover specific named structures (peripheral nerve, cranial nerve, parotid gland, extraocular muscles), and abdominal tissue as a target does not appear.
88466004 (Transposition of joint capsule)(not mapped)ICHI contains no code for transposition, repositioning, or reconstruction of a joint capsule; the only joint capsule codes available are for division (capsulotomy), and no general or site-specific capsule transposition code exists anywhere in the classification.
428808001 (Transtympanic injection of middle ear)(not mapped)ICHI contains no injection-into-middle-ear code (no CBA.DB.* exists in the middle ear block); the available middle ear codes cover incision, drainage, biopsy, excision, and repair but not injection, so no reasonable category-level match can be assigned.
449018006 (Transurethral injection of periureteral tissue)(not mapped)ICHI has no code for injection of periureteral tissue by any route; the ureter block (NAE) contains codes for ureterotomy, drainage, excision, and calculus extraction but no injection procedure. No reasonable ICHI match exists for this specific transurethral approach to the periureteral space.
304532001 (Treatment failure risk education)(not mapped)ICHI's education codes (PM action axis) are tied to specific body functions, behaviours, or environmental targets, and none captures education about treatment failure risk as a clinical concept — this is a meta-level educational intervention about treatment adherence and prognostic risk that has no suitable ICHI target-action combination. The closest candidates (e.g., medication-related education under UAC, or counselling for psychological functions) all impose a specific domain that misrepresents the scope of this concept.
304531008 (Treatment side effects education)(not mapped)ICHI education codes are all anchored to a specific body function, body system, or environmental factor (e.g., "Education about cardiovascular functions"); there is no code for education specifically about treatment side effects or adverse effects as a topic. No sufficiently close match exists across the classification.
386477002 (Triage: disaster)(not mapped)No ICHI code for triage exists — extensive searching across synonyms (sorting, prioritization, urgency, severity, emergency, patient management, classification, public health surveillance) yielded no concept representing the clinical act of triaging patients in a disaster setting. Triage is a care-coordination/decision process that does not map to any ICHI assignable category.
386478007 (Triage: emergency center)(not mapped)As with disaster triage, no ICHI assignable code represents the act of triaging patients in an emergency centre; the classification does not model patient prioritization or acuity-sorting workflows in any of its body-system, rehabilitation, or public-health sections.
8378006 (Trimming)(not mapped)"Trimming" as an unqualified generic procedure has no direct equivalent in ICHI, which does not use "trimming" as an action axis concept; the applicable code would depend entirely on the body site and clinical context (e.g., nail, bone, skin), which are unspecified here.
5337005 (Trocar biopsy)(not mapped)A trocar biopsy is a site-nonspecific technique using a hollow trocar needle to obtain a tissue core; ICHI requires a target body part as the first axis and has no body-site-agnostic biopsy code representing the technique alone. No ICHI category captures this procedure-type concept independent of anatomy.
406942005 (Tropaeolin O stain method)(not mapped)Tropaeolin O is a specific histochemical staining reagent used in laboratory analysis; ICHI classifies health interventions at the clinical procedure level and does not include laboratory staining techniques or specific reagent-based methods. No applicable ICHI code exists for this concept.
406943000 (Tropaeolin OO stain method)(not mapped)Tropaeolin OO is a specific histochemical dye used in laboratory staining protocols; ICHI contains no codes for specific staining methods or histochemical techniques, and the concept falls outside ICHI's scope of health interventions as it represents a laboratory analytical method rather than a patient-directed procedure.
234776005 (Try-in of maxillofacial prosthesis)(not mapped)ICHI contains no code for maxillofacial prosthesis fitting or trial fitting; the classification has codes for specific anatomical prostheses (penile, spinal disc, breast) and dental devices, but no entry covering maxillofacial prosthetics as a category, and the try-in procedure step has no ICHI representation at all.
406944006 (Trypan blue stain method)(not mapped)Trypan blue staining as a laboratory method (e.g., cell viability counting) does not correspond to any ICHI intervention category. ICHI does not cover in-vitro laboratory staining methods, and no staining, dye, or cell viability procedure exists in the classification.
413200004 (Tumor destruction)(not mapped)ICHI encodes destruction procedures at the level of specific body sites (e.g., "Destruction of lesion or tissue of brain", "Destruction of retina"), but has no generic cross-site "tumor destruction" concept. The SNOMED code is an abstract grouping that cannot be collapsed to any single ICHI category without knowing the target organ.
372302002 (Tumor quantitation)(not mapped)ICHI has no cross-site generic concept for quantifying or measuring a tumor; all assessment/measurement codes are anchored to specific body structures or physiological functions, and no residual category covers tumor burden quantification as a standalone procedure type.
16310003 (Ultrasonography)(not mapped)ICHI does not have a single generic assignable intervention code for ultrasonography — all ultrasound codes are tied to a specific anatomical target (e.g., ultrasound of kidney, ultrasound of brain). The axis value BJ ("Ultrasound, not otherwise specified") is a Means axis entry, not an assignable intervention category, so no valid ICHI code can be assigned to this unspecified/generic SNOMED concept.
770584000 (Ultrasonography guided cryoablation of lesion)(not mapped)ICHI has no code for cryoablation — the term does not appear in any form (cryotherapy, freeze, cold destruction), and no generic 'destruction of lesion, not elsewhere classified' code exists that would encompass an unspecified anatomical lesion. All destruction codes in ICHI are tied to specific organ/tissue targets, making it impossible to assign a reasonable match for this body-site-unspecified, technique-specific SNOMED concept.
866211009 (Ultrasonography guided localization of lesion)(not mapped)ICHI does not have a generic 'localization of lesion' code covering an unspecified body part, and no body-part-specific code can be selected since the SNOMED concept is intentionally non-specific. The procedure class (image-guided lesion localization/marking) has no equivalent ICHI category or block.
78938007 (Ultrasonography of multiple sites)(not mapped)ICHI is site-specific in its organisation and has no concept for ultrasonography of multiple or unspecified sites as a single intervention; the SNOMED concept represents a cross-cutting category with no equivalent structural position in ICHI.
1287912008 (Ultrasonography of nervous system)(not mapped)ICHI has separate ultrasound codes for specific nervous system structures (brain: AAA.BA.BJ; spinal cord: ABA.BA.BJ) but no single umbrella code for ultrasonography of the nervous system as a whole, and the 'interventions on nervous system, not elsewhere classified' block (AZZ) contains no imaging children.
1354766007 (Ultrasonography of peripheral nerve)(not mapped)The peripheral nerve block (ACA) contains MRI neurography codes (ACA.BA.BH/BI) but no ultrasound imaging code for peripheral nerve exists in ICHI. The ACA.BA axis does not include a BJ (ultrasound) means variant, leaving no reasonable mapping.
277667006 (Ultrasound guided biopsy)(not mapped)ICHI does not encode procedural guidance modality as a standalone procedure; ultrasound guidance is captured by the extension code XG8MR0 ('Ultrasonography guided') appended to a target-specific biopsy code, so there is no single ICHI category code representing ultrasound-guided biopsy generically across all target sites.
73874002 (Ultraviolet light examination of specimen)(not mapped)This SNOMED concept describes a laboratory/diagnostic procedure in which a specimen (not a patient body part) is examined under ultraviolet light (e.g., Wood's lamp examination of a hair or skin scraping for fungal fluorescence). ICHI covers clinical interventions on patients, not in-vitro specimen examination procedures, so no suitable ICHI code exists.
119986006 (Ureter injection)(not mapped)The full NAE (Interventions on ureter) block contains no code for injection, introduction of substance, or instillation into the ureter. No applicable ICHI category was identified across broader injection and substance-administration searches, leaving this concept without a reasonable ICHI match.
309848007 (Urinary stoma bag fitting)(not mapped)No ICHI code specifically represents the fitting or replacement of an external collection bag on a urinary stoma (urostomy bag); the closest structural codes (NAI.SN.AC — management of internal device for urinary bladder, or NAI.KA.AC — replacement of indwelling urinary catheter) refer to internal devices and do not capture external appliance/bag fitting. ICHI lacks a "management of external stoma appliance" code for the urinary system, making a meaningful mapping impossible.
241480000 (US scan of adrenals)(not mapped)The adrenal gland block (BlockL5-EBC) contains no ultrasound or general imaging code — only angiography and nuclear imaging are listed, with no BA.BJ category. No other ICHI code reasonably represents a dedicated adrenal ultrasound scan.
225369000 (Use of clean technique)(not mapped)ICHI has no code for the procedural technique of clean/aseptic technique as a standalone intervention; the hygiene behaviour block (VED) covers population-level hygiene interventions rather than clinician-applied clean technique during care delivery.
408809001 (Uterine contraction monitoring using external transducer)(not mapped)ICHI has no code for external uterine contraction monitoring (cardiotocography/tocometry via external transducer). The only fetal monitoring code (NMR.AI.AC "Internal fetal monitoring") refers to internal electrode-based monitoring and is not semantically equivalent.
237016003 (Uterine lavage)(not mapped)ICHI contains irrigation (action JA) codes for many organs but has no NME.JA code for the uterus, and no equivalent uterine washing or lavage category exists anywhere in the classification.
120029008 (Vas deferens destructive procedure)(not mapped)The NGD block (Interventions on spermatic cord) contains no destruction-action code (GA axis) for the vas deferens; the only codes present cover incision, excision, drainage, ligation, and repair. No reasonably equivalent ICHI category exists.
370861006 (Verification of consent for planned procedure)(not mapped)ICHI classifies health interventions by clinical action on a target body system, function, or health behaviour; administrative/governance processes such as consent verification do not correspond to any ICHI category or block.
3390006 (Verification routine)(not mapped)"Verification routine" is a broad administrative/process concept (e.g., surgical safety checklist steps) that falls entirely outside the scope of ICHI.
371576000 (Video imaging)(not mapped)ICHI does not have a generic "video imaging" code; video is used only as a specific modality qualifier within targeted procedure codes.
385894001 (Violence prevention)(not mapped)ICHI has no single assignable code for "violence prevention" as a general cross-cutting concept; violence-related codes are divided by sub-type and specific action.
412809002 (Viral hepatitis screening test)(not mapped)ICHI contains specific hepatitis B and C laboratory codes but no single code representing a generic viral hepatitis screening test spanning multiple types and modalities.
104246004 (Viral subtyping)(not mapped)No ICHI code exists for viral subtyping as a distinct laboratory or characterisation procedure.
408887001 (Vision care management)(not mapped)ICHI has no code for managing a vision care episode as a longitudinal concept; available codes address specific interventions on eye structures or functions.
310588009 (Visit by health visitor)(not mapped)A "health visitor" is a UK-specific professional role conducting community home visits; ICHI has no code representing a care episode defined by professional role or visit type.
406945007 (Vital new red stain method)(not mapped)Vital New Red is a specific supravital dye used in laboratory haematology/cytology; ICHI contains no laboratory staining or supravital staining codes.
104249006 (Vital stain method)(not mapped)Vital (supravital) staining is a laboratory technique used to stain living or recently living cells; ICHI does not classify laboratory staining methodologies.
252238009 (Vitamin A absorption test)(not mapped)ICHI does not classify individual laboratory analyte assays such as vitamin/micronutrient absorption tests; the Essential Laboratory Tests block contains no vitamin A or fat-soluble vitamin entries.
14598005 (Vitamin B12 measurement)(not mapped)ICHI contains no codes for serum/plasma vitamin or micronutrient measurement; the Essential Laboratory Tests block does not include B12 or haematinic assays.
252239001 (Vitamin C loading test)(not mapped)ICHI does not cover vitamin C or ascorbic acid assays, consistent with its exclusion of individual analyte laboratory tests outside its essential diagnostics scope.
117646009 (Volatile halogenated hydrocarbon identification)(not mapped)ICHI does not cover laboratory toxicological/chemical identification — this is an analytical or occupational-health technique with no corresponding ICHI category.
169268000 (Volumetry)(not mapped)Volumetry is a radiological measurement of organ/structure volume; ICHI has no generic volumetry code, and no body-specific volumetry code exists in relevant blocks.
709563009 (Voluntary care)(not mapped)"Voluntary care" denotes an administrative/legal context attribute (consent vs compulsory care), not a health intervention; ICHI has no axis capturing the voluntary versus compulsory nature of care.
183421009 (Voluntary social agency)(not mapped)This concept identifies a non-statutory care setting/referral destination rather than a health intervention; ICHI has no category corresponding to such an organisation as a concept.
167820005 (Vomit examination)(not mapped)Clinical/laboratory examination performed on vomitus as a specimen; ICHI does not index specimen-type-specific examinations of vomit or gastric contents.
167853000 (Vomit toxicology)(not mapped)Toxicological analysis of a vomit specimen; ICHI contains no categories for toxicological testing or specimen-based analysis of vomitus.
389270004 (Wandering precautions)(not mapped)Nursing safety protocol for elopement risk (e.g., dementia) involving environmental controls, supervision, and alarms; ICHI has no code for safety precautions/monitoring of this kind.
406946008 (Water soluble aniline blue stain method)(not mapped)ICHI does not include histological or cytological staining techniques — the classification covers health interventions, not laboratory stain protocols.
406948009 (Water soluble anthracene brown stain method)(not mapped)ICHI contains no laboratory staining procedures; this histochemical technique falls outside the scope of the classification.
406947004 (Water soluble nigrosine stain method)(not mapped)ICHI does not represent laboratory staining methods of any kind; this nigrosine stain technique has no corresponding concept within the classification.
229573005 (Wax bandage treatment)(not mapped)Paraffin wax is a superficial thermotherapy applied to skin; ICHI contains no paraffin bath, wax therapy, or superficial heat application codes.
1237137001 (Waxing up of teeth on trial maxillofacial prosthesis)(not mapped)Dental laboratory/prosthodontic technique step (trial wax-up of a prosthesis); ICHI does not cover prosthesis manufacturing or laboratory workflow steps.
406949001 (Waxoline blue stain method)(not mapped)Waxoline blue is a histochemical staining technique used in laboratory/pathology settings; ICHI does not include histochemical staining methods or specimen processing codes.
90982009 (Wedge filter design and fabrication)(not mapped)Radiation therapy physics/dosimetry workflow — design and construction of a beam-shaping device; ICHI has no code for technical planning or device fabrication for radiation beam modifiers.
48745007 (Western blot assay)(not mapped)ICHI does not include a code for Western blot (immunoblot) assay as a technique; the essential laboratory test extension codes cover specific analyte-based tests rather than the detection methodology. No fuzzy or synonym search produced a relevant match for this gel electrophoresis and membrane transfer technique.
17443007 (Windowing of cast)(not mapped)Windowing of a cast (cutting an opening in an applied cast to inspect or treat the underlying skin/wound) is a distinct procedure from cast application or replacement; ICHI contains codes for applying (PZX.LC.AH) and replacing (PZX.KB.AH) external immobilisation devices but no code representing modification, trimming, or windowing of an existing cast.
406950001 (Xylene cyanol FF stain method)(not mapped)Xylene cyanol FF is a tracking dye used in gel electrophoresis and other laboratory analytic techniques; ICHI does not index laboratory staining or dye methods at this level of specificity, and no suitable category or block was found covering histochemical or electrophoretic staining procedures.
73214001 (Yeast identification procedure)(not mapped)ICHI does not contain codes for microbiological or mycological identification procedures such as yeast identification; the Essential Laboratory Tests block covers a narrow set of point-of-care tests and does not include organism identification or fungal culture, leaving no reasonable ICHI match.
406979008 (Ziehl-Neelsen stain method)(not mapped)Ziehl-Neelsen staining is a specific laboratory staining method for acid-fast bacilli (e.g., Mycobacterium tuberculosis), and ICHI does not classify laboratory staining techniques or histological/microbiological staining methods as health interventions.
225248004 (Zona drilling)(not mapped)Zona drilling is an assisted hatching technique in assisted reproductive technology (ART) where a hole is mechanically drilled in the zona pellucida of an embryo to facilitate implantation; ICHI's fetal/embryonic structure block (NMR) does not contain a code for this pre-implantation embryo manipulation.
121349001 (1,1-Dichloro-2,2-bis(p-chlorophenyl)ethane measurement)(not mapped)DDD is a specific organochlorine pesticide metabolite measured in biological specimens; ICHI contains no codes for specific chemical or pesticide level measurements, and the Essential Laboratory Tests block covers only a curated set of general clinical tests with no chemical exposure testing in scope.
121260008 (1,4-Dioxane measurement)(not mapped)1,4-Dioxane is an industrial solvent whose measurement is an occupational/environmental exposure test; no ICHI codes exist for specific organic solvent measurements, and there is no applicable broader category in ICHI that would represent this class of analyte without severe semantic distortion.
71413001 (17-Ketosteroids measurement, fractionation, urine)(not mapped)ICHI does not include codes for specific endocrine analyte measurements such as urinary 17-ketosteroid fractionation; the Essential Laboratory Tests block covers only a small curated set of global-health-priority tests and does not extend to hormone metabolite panels.
104641002 (2,3-diphosphoglycerate measurement)(not mapped)2,3-DPG is a highly specific red blood cell metabolite assay used in haematology and transfusion medicine; ICHI has no code for this analyte or its functional category, and the phosphate code (XG2C47) in the Essential Laboratory Tests block refers to inorganic serum phosphate, making it semantically incompatible.
105042001 (2,4 toluenediamine measurement)(not mapped)ICHI contains no code for measurement of specific industrial aromatic amines such as toluenediamine; the Essential laboratory tests block (BlockL1-XG1) covers only a small WHO-prioritised set of tests and does not include occupational/toxicological chemical analytes at this level of specificity.
121366004 (2,4-Dinitrophenylhydrazine measurement)(not mapped)No ICHI code exists for measurement of 2,4-DNPH or any comparable reagent/ketone-detection compound; searches across laboratory, biochemical, and toxicology terminology returned no relevant match, and the nearest candidate (XG0S88 Ketones) refers to a clinical urinalysis strip result rather than a specific analytical chemistry measurement.
121367008 (2,5-Hexanedione measurement)(not mapped)ICHI has no code for measurement of n-hexane metabolites such as 2,5-hexanedione; occupational toxicology biomarker assays of this specificity fall entirely outside the scope of the ICHI Essential laboratory tests block and no broader laboratory measurement category is present in ICHI that would reasonably accommodate this concept.
105043006 (2,6 toluenediamine measurement)(not mapped)Like its 2,4-isomer counterpart, measurement of 2,6-toluenediamine is an industrial aromatic amine biomarker assay for which ICHI has no corresponding code; neither keyword nor fuzzy searches across all ICHI laboratory, chemical, and toxicology terminology yielded any applicable category.
121801001 (2-Ethyl-3-hydroxypropionate measurement)(not mapped)2-Ethyl-3-hydroxypropionate is a specific organic acid metabolite measured in organic aciduria investigation; ICHI contains no code for individual organic acid analyte measurements, and the metabolic measurement codes present (e.g., ETB.AB.ZZ Measurement of metabolic rate) describe functional physiological measurements rather than specific biochemical analyte quantification.
117707004 (2-Methoxy-2-methylpropane measurement)(not mapped)MTBE (methyl tert-butyl ether) is an industrial fuel additive measured in occupational/environmental toxicology; ICHI contains no codes for specific chemical exposure biomonitoring or industrial solvent assays, and no broader laboratory category reasonably covers this occupational analyte measurement.
121733000 (2-Methoxyethanol measurement)(not mapped)2-Methoxyethanol is an industrial solvent whose measurement is an occupational biomonitoring assay; ICHI has no codes for industrial chemical exposure testing or individual solvent metabolite assays, and no available broader category is close enough to constitute even a "wider" match.
117708009 (2-Methylpentane measurement)(not mapped)2-Methylpentane is a hydrocarbon solvent measured in occupational toxicology, but ICHI contains no codes for measurement of specific chemical compounds, solvents, or toxicants. ICHI's scope for chemical substance interventions covers population-level public health actions (e.g., manufacture restrictions), not clinical analyte quantification.
121885007 (2-Oxo,3-methylvalerate measurement)(not mapped)This is quantification of a specific branched-chain alpha-keto acid (a marker for maple syrup urine disease), but ICHI has no codes for measurement of individual metabolites or organic acids. The closest ICHI territory — ETB.AB.ZZ "Measurement of metabolic rate" — concerns physiological function measurement rather than biochemical analyte assay, making any mapping inappropriate.
121886008 (2-Oxoadipate measurement)(not mapped)2-Oxoadipate is a dicarboxylic keto acid relevant to inborn errors of lysine/tryptophan metabolism; no ICHI code exists for its measurement or for any specific organic acid assay. ICHI is coarser than SNOMED in the laboratory domain and does not represent individual analyte measurements at this level of specificity.
105044000 (2-oxoisocaproate measurement)(not mapped)2-Oxoisocaproate (alpha-ketoisocaproic acid) is a branched-chain keto acid marker for maple syrup urine disease, but ICHI contains no codes for individual metabolite or keto acid quantification. No broader ICHI laboratory or metabolic measurement code is specific enough to constitute even a "wider" match without being misleading.
121888009 (2-Oxoisovalerate measurement)(not mapped)2-Oxoisovalerate (alpha-ketoisovaleric acid) is another branched-chain keto acid assayed in maple syrup urine disease workup; as with the other keto acid concepts, ICHI has no code representing individual biochemical analyte measurement. The classification's laboratory section (XG1 block "Essential laboratory tests") covers only a limited set of common tests and does not include metabolic disease marker assays.
121289005 (3-Hydroxybutyrate measurement)(not mapped)Although ICHI has a "Ketones" extension code (XG0S88) under Essential laboratory tests, this refers to the standard qualitative urine ketone dipstick test rather than a quantitative serum/plasma 3-hydroxybutyrate assay; assigning it would be a clinically misleading stretch, so unmatched is the appropriate equivalence.
121301007 (3-Methoxy-o-desmethylencainide measurement)(not mapped)3-Methoxy-o-desmethylencainide is a pharmacokinetic metabolite of the antiarrhythmic drug encainide, measured for therapeutic drug monitoring; ICHI has no codes for individual drug or drug-metabolite level measurements at this level of specificity.
121307006 (4-Aminobutyrate measurement)(not mapped)4-Aminobutyrate (GABA) measurement is a specialised neurochemical/metabolic assay not represented in ICHI; exhaustive searching across laboratory, measurement, amino-acid, and metabolite terms yielded no applicable ICHI code.
121308001 (4-Hydroxyglutethimide measurement)(not mapped)4-Hydroxyglutethimide is a sedative drug metabolite measured in toxicology or therapeutic drug monitoring; ICHI does not include codes for individual drug or drug-metabolite level assays, and no suitable broader category was found.
121317001 (6-beta-Naltrexol measurement)(not mapped)6-beta-Naltrexol is a pharmacologically active metabolite of naltrexone measured for therapeutic drug monitoring; ICHI has no codes for therapeutic drug monitoring, drug metabolite assays, or any related analyte-level laboratory test at this specificity.
121320009 (8-Hydroxyloxapine measurement)(not mapped)8-Hydroxyloxapine is an antipsychotic drug metabolite measured as part of therapeutic drug monitoring; ICHI contains no code for drug metabolite measurement or any sufficiently related category, making a reasonable mapping impossible.
121321008 (9-Hydroxyrisperidone measurement)(not mapped)ICHI does not contain a category for measuring drug metabolite concentrations (therapeutic drug monitoring). The Essential Laboratory Tests block covers only a narrow set of infectious disease and basic chemistry tests, and no code exists for antipsychotic or metabolite serum measurement.
243123002 (Ablative hormone therapy)(not mapped)ICHI contains no code for hormonal or endocrine ablation therapy (e.g. medical or surgical castration, anti-androgen or anti-estrogen treatment). The pharmacotherapy codes in ICHI (e.g. PZA.DB.AZ) are too generic and do not capture the specific meaning of ablative hormone suppression.
13227004 (Acetaldehyde measurement)(not mapped)ICHI's Essential Laboratory Tests section (BlockL1-XG1) covers only a limited set of priority global health tests and does not include specific analyte measurements such as acetaldehyde; no ICHI code exists for biochemical measurement of this specific alcohol metabolite.
57173006 (Acetaminophen measurement, urine)(not mapped)While XG0NB5 (Urine chemistry) exists as an extension/lab code, it is a generic extension code rather than an assignable procedural category, and ICHI does not include specific drug-level measurements such as urine acetaminophen (paracetamol); the Essential Laboratory Tests block does not cover therapeutic drug monitoring analytes.
121358008 (Acetate measurement)(not mapped)ICHI does not contain any code for measurement of acetate (a specific biochemical analyte) in biological fluids; the classification does not model individual analyte quantifications at this level of specificity. No related broader code captures single-analyte biochemistry measurement in a clinically useful way.
252689003 (Acetic acid test)(not mapped)In SNOMED CT this concept refers to visual inspection with acetic acid (VIA) for cervical cancer screening, but ICHI has no dedicated code for VIA; the closest found code — NMF.AE.AC (Colposcopy) — is a distinct, more invasive procedure involving optical magnification rather than the simple acetic acid application technique, making it semantically inappropriate as a mapping.
105050005 (Acetone measurement)(not mapped)While ICHI contains the extension code XG0S88 (Ketones), this is a supplementary descriptor code, not an assignable standalone intervention code representing the act of measuring acetone or ketones; no ICHI category code captures this specific analyte measurement procedure.
104459009 (Acetonitrile measurement)(not mapped)Acetonitrile is an industrial/toxic solvent; measurement of acetonitrile (e.g., in blood or urine for occupational or toxicological purposes) has no representation in ICHI, which lacks codes for individual toxic substance quantification at this level of analyte specificity.
121734006 (Acetylene measurement)(not mapped)Acetylene measurement (used historically in cardiac output determination or as an occupational exposure marker) has no corresponding ICHI code; ICHI does not classify individual gaseous analyte measurements, and no sufficiently related broader code exists to serve as a meaningful partial match.
64327005 (Acid fast fluorochrome stain method)(not mapped)ICHI does not represent specific staining methodologies such as fluorochrome or Ziehl-Neelsen staining; the essential laboratory tests block (BlockL1-XG1) covers selected high-level tests but contains no code for acid-fast staining techniques.
67122001 (Acid fast stain method)(not mapped)The generic acid-fast stain method has no ICHI representation; ICHI's laboratory section does not encode staining procedures as standalone interventions, and microscopy codes are too broad and conceptually distinct to constitute a relatedto match.
121735007 (Aconitate measurement)(not mapped)Aconitate is a specific organic acid measured for metabolic disorder workup; ICHI has no code for this analyte or for urine organic acid profiling generally. Generic urine chemistry codes are far too broad and would misrepresent the specificity of this quantitative metabolite assay.
116997007 (Acridine orange stain method)(not mapped)Acridine orange is a fluorescent staining technique used in microbiology and cytology; ICHI does not classify individual laboratory staining methods, and exhaustive searching across staining, fluorescent, histology, and laboratory categories returned no applicable code.
406805004 (Acriflavine stain method)(not mapped)Acriflavine is a specific fluorescent dye-based laboratory method not represented in ICHI; like acridine orange, it falls outside ICHI's classification scope, which covers clinical health interventions rather than named reagent-based laboratory staining techniques.
121360005 (Acrolein measurement)(not mapped)Acrolein is a specific reactive aldehyde biomarker; no ICHI code exists for measuring specific chemical compounds in blood or urine, and the essential laboratory tests block contains only named clinical assays with no general biochemical analyte measurement category applicable here.
121736008 (Acrylamide measurement)(not mapped)ICHI does not include laboratory analyte-specific measurement codes for individual chemicals or toxins such as acrylamide; its measurement codes cover physiological functions and body-part dimensions rather than specific substance assays.
105052002 (Acrylonitrile measurement)(not mapped)Acrylonitrile is a specific industrial chemical whose serum/urine quantification is outside ICHI's scope — ICHI does not classify laboratory analyte measurement at the individual chemical level.
395209005 (Activated protein C ratio (factor V Leiden deficient plasma))(not mapped)ICHI does not contain a code for activated protein C ratio testing, factor V Leiden assays, or thrombophilia panels; the essential laboratory tests block covers only a restricted set of common tests and this specific coagulation assay is not among them.
41833004 (Activated protein C resistance assay)(not mapped)ICHI has no code for activated protein C resistance testing or any equivalent thrombophilia/coagulation resistance assay; available coagulation extension codes are for general coagulation screening tests (PT/INR, PTT) and do not cover this specific resistance assay.
104465009 (Acylcarnitine measurement)(not mapped)ICHI does not contain codes for specific biochemical analyte measurements such as acylcarnitine or carnitine profiles; the Essential Laboratory Tests block covers only a narrow set of high-priority tests, and metabolic function codes address functional assessment rather than discrete laboratory analyte quantification.
281185004 (Add to maxillofacial prosthesis)(not mapped)ICHI contains no concept covering modification or addition to an external maxillofacial/facial prosthesis; searches across prosthesis, facial, maxillofacial, craniofacial, and external device terms returned no applicable code.
104469003 (Adenosine 5'-triphosphate measurement)(not mapped)ICHI does not classify individual analyte-level laboratory assays at the specificity of ATP measurement; its laboratory section (XG essential tests) covers only a narrow set of screening-level tests, and its functional measurement codes are far too broad to constitute a reasonable match.
104472005 (Adenosine diphosphate measurement)(not mapped)As with ATP measurement, ICHI lacks any code for individual nucleotide or purine metabolite assays; no ICHI category or block corresponds to ADP measurement at any meaningful level of specificity.
104477004 (Adipate measurement)(not mapped)Adipate (a dicarboxylic acid measured in organic acid urine panels) is a highly specific analyte not represented in ICHI; the classification has no codes for individual organic acid measurements, and the nearest functional categories are semantically too distant.
1285535000 (Adjunctive periodontal procedure)(not mapped)ICHI contains no periodontal procedure code; the periodontium appears only as an anatomy extension entity, and the gingiva/tooth procedure codes (KAG, KAE blocks) each represent specific individual procedures rather than the broad adjunctive/supportive periodontal category this SNOMED concept denotes.
735927006 (Adjustment of external breast prosthesis)(not mapped)ICHI's breast interventions block (LCA) contains LCA.SN.AE only for implanted internal devices, not external prostheses worn by the patient. No ICHI code exists for fitting, adjustment, or management of an external breast prosthesis.
450507000 (Adjustment to internal fixation device)(not mapped)ICHI does not contain a generic "adjustment of internal fixation device" code applicable across body sites; the classification has site-specific codes for applying or removing internal bone devices, but none for post-operative adjustment of an internal orthopaedic fixation device as a standalone procedure.
431463004 (Administration of aspirin)(not mapped)ICHI has no general "administration of non-immunological drug" category code — the DTB block is restricted to immunological agents, and UAC.RD.ZZ ("Providing medications") is a public health supply concept rather than a clinical drug administration act.
698511005 (Administration of hormone via oral route)(not mapped)ICHI has no code for oral administration of a hormonal agent; the endocrine function block (ETK) contains only assessment, education, and counselling codes with no pharmaceutical administration entries, and existing oral drug codes are tied to immunological or respiratory targets.
1287783000 (Administration of human immunodeficiency virus pre-exposure prophylaxis)(not mapped)ICHI contains no code for antiretroviral chemoprophylaxis or HIV PrEP; HIV-related codes in ICHI are exclusively diagnostic tests, and pharmaceutical administration codes are not present at the specificity needed to represent HIV PrEP as a clinical intervention.
