External Identifier Systems

HL7 Terminology (THO), published by HL7 International - Vocabulary Work Group. This guide is not an authorized publication; it is the continuous build for version 5.5.0 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

Identifier Systems that are defined here are for the convenience of HL7 implementers. These resources serve the special purpose of capturing for easy access descriptive metadata information about each system of identifiers registered here.

These pages contain the metadata information for systems of identifiers that are published in the HL7 Terminology pages.

The systems here are typically used in data types supporting identifier systems, often called namespaces.
