This page is part of the HL7 Terminology (v1.0.0: Release) based on FHIR R4. The current version which supercedes this version is 5.2.0. For a full list of available versions, see the Directory of published versions
Naming Systems that are defined here are for the convenience of HL7 implementers. These naming system resources serve the special purpose of capturing for easy access multiple different identifiers for Code Systems that have been used in the past, as well as those that are currently preferred. THey are made available here for those that are looking for identifiers that may have been published in the past in HL7 Standards, but have been superceded since that time.
