Guidance on how to interpret the contents of this table can be foundhere

0. ServiceRequest
Definition | A record of a request for service such as diagnostic investigations, treatments, or operations to be performed.
Short | A request for a service to be performed
Control | 0..*
Is Modifier | false
Must Support | false
Complies with Profile | This profile complies with the profile US Core ServiceRequest Profile
Summary | false
Alternate Names | diagnostic request, referral, referral request, transfer of care request
Invariants | dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (contained.contained.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()) dom-5: If a resource is contained in another resource, it SHALL NOT have a security label (contained.meta.security.empty()) dom-6: A resource should have narrative for robust management (text.`div`.exists()) prr-1: orderDetail SHALL only be present if code is present (`orderDetail.empty() or code.exists()`) prr-1: orderDetail SHALL only be present if code is present (orderDetail.empty() or code.exists())
2. ServiceRequest.implicitRules
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Short | A set of rules under which this content was created
Comments | Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.
Control | 0..1
Type | uri
Is Modifier | true because This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count()))
4. ServiceRequest.contained
Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.
Short | Contained, inline Resources
Comments | Any references found in this resource, with the exception of 'Patient' could potentially be resource-specific and thus transmitted as contained resources. This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.
Control | 0..*
Type | Resource
Is Modifier | false
Must Support | true
Summary | false
Alternate Names | inline resources, anonymous resources, contained resources
6. ServiceRequest.extension
Definition | An Extension May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short | ExtensionAdditional content defined by implementations
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Control | 0..*
Type | Extension
Is Modifier | false
Summary | false
Alternate Names | extensions, user content
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
Slicing | This element introduces a set of slices on `ServiceRequest.extension`. The slices areUnordered and Open, and can be differentiated using the following discriminators: value @ url
8. ServiceRequest.extension:Coverage-Information
Slice Name | Coverage-Information
Definition | Indicates coverage information.
Short | Coverage Info
Control | 0..* This element is affected by the following invariants: ele-1
Type | Extension(Coverage Information) (Complex Extension)
Is Modifier | false
Must Support | true
Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`) ext-1: Must have either extensions or value[x], not both (`extension.exists() != value.exists()`) crd-ci-q1: Questionnaire is only allowed when doc-needed exists (`extension.where(url='questionnaire').exists() implies extension.where(url = 'doc-needed').exists()`) crd-ci-q2: If covered is set to 'not-covered', then 'pa-needed' must not exist. (`extension.where(url = 'covered' and value = 'not-covered').exists() implies extension.where(url = 'pa-needed').exists().not()`) crd-ci-q3: 'info-needed' SHALL exist if and only if at least one of 'covered', 'pa-needed', or 'doc-needed' is set to 'conditional'. (`extension.where((url = 'covered' or url = 'pa-needed' or url = 'doc-needed') and value = 'conditional').count() >= 1 implies extension.where(url = 'info-needed').exists()`) crd-ci-q4: If 'pa-needed' is 'satisfied', 'noauth', or 'not-covered', then 'Doc-purpose' cannot be 'withpa'. (`extension.where(url = 'pa-needed' and (value = 'satisfied' or value = 'noauth' or value = 'not-covered')) and extension.where(url = 'doc-purpose').exists() implies extension.where(url = 'doc-purpose').all(value != 'withpa')`) crd-ci-q5: 'satisfied-pa-id' must exist if and only if 'pa-needed' is set to 'satisfied'. (`extension.where(url = 'pa-needed' and value = 'satisfied').exists() = extension.where(url = 'satisfied-pa-id').exists()`) crd-ci-q6: If 'info-needed' is OTH, then reason must be specified (`extension.where(url = 'info-needed' and value = 'OTH').exists() implies extension.where(url = 'reason').exists()`) crd-ci-q7: If reason.coding is present and is not from the extensible value set, then reason.text must be present (`extension.where(url = 'reason').empty() or extension.where(url = 'reason').value.text.exists() or extension.where(url = 'reason').value.memberOf('http://hl7.org/fhir/us/davinci-crd/ValueSet/coverageAssertionReasons')`) crd-ci-q8: If doc-purpose is present with a value other than 'conditional', then reason must be present (`extension.where(url = 'doc-purpose' and value != 'conditional').exists() implies extension.where(url = 'reason').exists()`) crd-ci-q9: If any of 'covered', 'pa-needed', or 'doc-needed' is set to 'indeterminate', then reason must be present to explain the issue that is preventing the payer from making a coverage determination. (`extension.where((url = 'covered' or url = 'pa-needed' or url = 'doc-needed') and value = 'indeterminate').count() >= 1 implies extension.where(url = 'reason').exists()`)
10. ServiceRequest.modifierExtension
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Short | Extensions that cannot be ignored
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Control | 0..*
Type | Extension
Is Modifier | true because Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
Summary | false
Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.
Alternate Names | extensions, user content
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists())
12. ServiceRequest.identifier
Definition | Identifiers assigned to this order instance by the orderer and/or the receiver and/or order fulfiller.
Short | Identifiers assigned to this order
Comments | The identifier.type element is used to distinguish between the identifiers assigned by the orderer (known as the 'Placer' in HL7 v2) and the producer of the observations in response to the order (known as the 'Filler' in HL7 v2). For further discussion and examples see the resource notes section below.
Note | This is a business identifier, not a resource identifier (see discussion)
Control | 0..*

16. ServiceRequest.status
Definition | The status of the order.
Short | draft | active | on-hold | revoked | completed | entered-in-error | unknown
Comments | This will be 'draft' when using order-select or an initial order-sign, but may be 'active' or other values for order-sign representing edits to the order or for order-dispatch. The status is generally fully in the control of the requester - they determine whether the order is draft or active and, after it has been activated, competed, cancelled or suspended. States relating to the activities of the performer are reflected on either the corresponding event (see Event Pattern for general discussion) or using the Task resource.
Control | 1..1
Binding | The codes SHALL be taken from RequestStatus http://hl7.org/fhir/ValueSet/request-status|4.0.1 (required to `http://hl7.org/fhir/ValueSet/request-status|4.0.1` ) The status of a service order.

Slicing | This element introduces a set of slices on `ServiceRequest.category`. The slices areUnordered and Open, and can be differentiated using the following discriminators: pattern @ $this
22. ServiceRequest.category:us-core
Slice Name | us-core
Definition | A code that classifies the service for searching, sorting and display purposes (e.g. "Surgical Procedure").
Short | Classification of service
Comments | There may be multiple axis of categorization depending on the context or use case for retrieving or displaying the resource. The level of granularity is defined by the category concepts in the value set.

28. ServiceRequest.doNotPerform
Definition | Set this to true if the record is saying that the service/procedure should NOT be performed.
Short | True if service/procedure should not be performed
Comments | In general, only the code and timeframe will be present, though occasional additional qualifiers such as body site or even performer could be included to narrow the scope of the prohibition. If the ServiceRequest.code and ServiceRequest.doNotPerform both contain negation, that will reinforce prohibition and should not have a double negative interpretation. Client systems that do not allow ordering services with 'doNotPerform' of 'true' do not need to add support for this capability. CRD servers SHALL understand this element if populated. Typically, 'doNotPerform' orders will not result in coverage-related card responses and might not result in any decision support at all. In some cases, a payer might have documentation or other requirements relating to doNotPerform orders that they wish to communicate. In general, only the code and timeframe will be present, though occasional additional qualifiers such as body site or even performer could be included to narrow the scope of the prohibition. If the ServiceRequest.code and ServiceRequest.doNotPerform both contain negation, that will reinforce prohibition and should not have a double negative interpretation.
Control | 0..1
Type | boolean
Is Modifier | true because If true this element negates the specified action. For Example, instead of a request for a procedure, it is a request for the procedure to not occur.
Primitive Value | This primitive element may be present, or absent, or replaced by an extension

30. ServiceRequest.code
Definition | A code that identifies a particular service (i.e., procedure, diagnostic investigation, or panel of investigations) that have been requested.
Short | Codes to identify requested services. (CPT, SNOMED CT or LOINC)What is being requested/ordered
Comments | Many laboratory and radiology procedure codes embed the specimen/organ system in the test order name, for example, serum or serum/plasma glucose, or a chest x-ray. The specimen might not be recorded separately from the test code.
Control | 10..1
Binding | Unless not suitable, these codes SHALL be taken from For example codes, see CRD Service Request Codes Value Set http://hl7.org/fhir/ValueSet/procedure-code|4.0.1 (extensible to `http://hl7.org/fhir/us/davinci-crd/ValueSet/serviceRequestCodes` ) Codes describing the type of Service Codes for tests or services that can be carried out by a designated individual, organization or healthcare service.

Slice Name | codeOptions
Definition | A logical reference (i.e. a reference to ValueSet.url) to a value set (and optionally a version) that identifies a set of possible coded values for the element. This extension is used to convey a list of candidate codes when there is no formal code in the code system already defined that captures the intended set. For example, the concept of COVID preventative medications could be expressed as a value set because there is no specific code representing that concept.
Short | Url of a value set of activities
Comments | This extension SHALL NOT be used when an appropriate higher level concept code exists. This extension cannot be used to satisfy a required binding. When this extension is used on an element with an extensible binding, the set of possible coded values in the referenced value set SHALL be present in the bound value set unless none of the codes in the bound value set apply to the concept being communicated (based on human review). When this extension appears on a CodeableConcept, the CodeableConcept SHALL have no codings, and the text of the CodeableConcept SHOULD be present.

Short | A set of rules under which this content was created
Comments | Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense.

The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.
Short | Text summary of the resource, for human interpretation
Comments | Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied).

18. ServiceRequest.modifierExtension
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Short | Extensions that cannot be ignored
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Control | 0..*
Type | Extension
Is Modifier | true because Modifier extensions are expected to modify the meaning or interpretation of the resource that contains them
Summary | false
Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

Short | Instantiates FHIR protocol or definition
Comments | Note: This is a business identifier, not a resource identifier (see discussion). It is best practice for the identifier to only appear on a single resource instance, however business practices may occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and a Person resource instance might share the same social insurance number.

112. ServiceRequest.reasonCode.extension
Definition | May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Short | Additional content defined by implementations
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.
Invariants | ele-1: All FHIR elements must have a @value or children (`hasValue() or (children().count() > id.count())`)
120. ServiceRequest.reasonReference
Definition | Indicates another resource that provides a justification for why this service is being requested. May relate to the resources referred to in `supportingInfo`.
Short | 𝗔𝗗𝗗𝗜𝗧𝗜𝗢𝗡𝗔𝗟 𝗨𝗦𝗖𝗗𝗜: US Core Profile that supports the requested service
Comments | Observations SHOULD use US Core profiles when applicable, but not all relevant observations have appropriate US Core profiles (and there are too many to practically list all US Core profiles).

This information includes diagnosis, clinical findings and other observations. In laboratory ordering these are typically referred to as "ask at order entry questions (AOEs)". This includes observations explicitly requested by the producer (filler) to provide context or supporting information needed to complete the order. For example, reporting the amount of inspired oxygen for blood gas measurements.

126. ServiceRequest.specimen
Definition | One or more specimens that the laboratory procedure will use.
Short | Procedure Samples
Comments | Many diagnostic procedures need a specimen, but the request itself is not actually about the specimen. This element is for when the diagnostic is requested on already existing specimens and the request points to the specimen it applies to.
