Code Systems

See the FHIR terminology section for a complete discussion on code systems and a list of code system names used in FHIR. Most code systems used in this guide are defined in the base FHIR specification. However, the following code systems are unique to this guide and not listed in the base FHIR specification. If a URI is listed here, it SHALL be used in the US Core profiles to identify the code system in preference to any other code system URI.

Code systems published in this IG*- Includes US Core defined code systems and externally defined code systems

67 Logical Observation Identifiers http://loinc.org LOINC provides a set of universal names and ID codes for identifying laboratory and clinical test results.1
2 LOINC facilitates the exchange and pooling of results
such as blood hemoglobin
serum potassium
or vital signs
for clinical care
outcomes management
and research. LOINC's universal identifiers (names and codes) can be used in the context of order and observation exchanges between information systems that use syntax standards such as HL73
CEN TC251
ISO TC215
ASTM4
and DICOM. Specifically
the identifier can be used as the coded value for an observation in any other standard that uses the observation/observation value paradigm
whether messages
documents
application programming interface (API)
etc. For example
LOINC codes are used widely in the OBX segment Observation Identifier field (OBX-3) of an ORU HL7 (HL7 version 2.x or ASTM 1238-9410) message that may be sent between a Clinical Laboratory Information Management Systems (LIMS) and Electronic Health Record Systems (EHR).5
6 In this way
LOINC codes provide universal identifiers that allow the exchange of clinical data between heterogeneous computing environments.

The Value Set Authority Center (VSAC)

This guide links terminology directly to the FHIR® Terminology Service for VSAC Resources (Value Set Authority Center (VSAC)), where applicable, using a RESTful API service to access the VSAC value sets and supported code systems. See the table above for a list of value sets used in US Core that VSAC defines.

How to Acess Value Sets in VSAC

  • VSAC requires login using your own UMLS API Key to view the value sets. VSAC UMLS Licensing information. (See the screenshots below)
  • The value sets in VSAC are specified using a VSAC value set OID.
  • To view the value set expansion in the VSAC user interface, use:

    GET https://vsac.nlm.nih.gov/ValueSet/[VSAC OID]/expansion

    An example of this is shown in the screenshots below.

  • To fetch the FHIR ValueSet resource (in other words, the value set definition), use:

    GET https://cts.nlm.nih.gov/fhir/ValueSet/[VSAC OID]

  • To fetch the FHIR ValueSet resource expansion, use the FHIR $expand operation:

    GET https://cts.nlm.nih.gov/fhir/ValueSet/[VSAC OID]/$expand
