HL7 Terminology (THO), published by HL7 International - Vocabulary Work Group. This guide is not an authorized publication; it is the continuous build for version 6.5.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/UTG/ and changes regularly. See the Directory of published versions
This page contains the FHIR code systems that are available for browsing through the HL7 Terminology pages. The docuemnttion here refers specifically to the use of this content in FHIR artifacts.
The code system names and their URIs may be used in the system element of the Coding data type. If a URI is defined here, it SHALL be used in preference to any other identifying mechanisms. If a code system is not listed here, the correct URI may be determined by working through the following list, in order:
See also the list of known identifier systems that can be used in the system element of the Identifier data type. Additional identifier systems may be registered on the HL7 FHIR registry at http://hl7.org/fhir/registry.
Important Notes:
http://example.org is reserved for testing and documentation purposes.Note that the code systems are available as FHIR resources - see the Downloads Page (as part of the FHIR definitions) (excluding the External code systems.
UMLS Note: The UMLS includes many code systems that do
not have an entry in the table below, or in the HL7 OID registry, or on http://registry.fhir.org. Until these code systems
are registered, implementers may use the pattern http://www.nlm.nih.gov/research/umls/[SAB], where [SAB] is the lowercase of
abbreviation of the code system as provided by UMLS. e.g. The system for "Multum MediSource Lexicon" would then be
http://www.nlm.nih.gov/research/umls/mmsl. Implementers choosing to use this pattern should be aware that very
often, when the code system is registered, it will use a different system.
It has been noted that this UMLS statement above is not completely correct, and the UTG team is awaiting the correction. Stay tuned.
