This page is part of the FHIR Specification (v1.1.0: STU 3 Ballot 1). The current version which supercedes this version is 5.0.0. For a full list of available versions, see the Directory of published versions . Page versions: R4 R3 R2
This is a frozen snapshot of the FHIR specification created for the purpose of balloting the GAO implementation Guide. It includes draft changes that may be part of the future DSTU 2.1 release but further change is expected. Readers should focus solely on the GAO implementation content, and FHIR DSTU 2 for other purposes.
These system namespaces are defined for use in FHIR when
representing codes that were defined as part of the HL7 v2 tables
in FHIR instances. So if you are representing the code "M" from
table 0001 in HL7 v2.3.1 in a FHIR instance, then you would use
the system "http://hl7.org/fhir/v2/0001".
There are a number of subtle but serious issues with using tables defined for HL7 v2 as code systems, so some of these tables are mapped to a different namespace for each version. All of these namespaces are subject to further change as additional review of the tables proceeds.
