FHIR® Terminology Service for VSAC Resources


The FHIR Terminology Service for VSAC Resources is a RESTful API service for accessing the VSAC value sets and supported code systems. This service requires a free Unified Medical Language System® Metathesaurus License , due to usage restrictions on some of the codes included in the value sets.


    Capability Statement: FHIR Version 3.0.1

    (also available as XML or JSON)

Base URI: https://cts.nlm.nih.gov/fhir

    NOTICE:

  • The VSAC implementation of FHIR cannot retrieve intensional value sets. Use the SVS API to retrieve intensional value sets.
  • VSAC value set identifiers must be specified as a VSAC value set OID. Value set names are not unique in VSAC.
