External Terminologies

External terminologies information defined by HL7 and published in HL7 International Standards

The list of external systems here consists of two types of systems maintained by HL7 through the Unified Terminology Governance (UTG) process, and published by HL7 in the different HL7 product families. Currently these are information and history tracking for changed primary technical identifiers (URIs and OIDs) for External Code Systems (published by organizations outside of HL7), and Pending Code Systems, ie defined planned URIs and names that will be created in THO soon but are not yet present. The information captured in these resources is persisted and rendered here from underlying NamingSystem resources. Updates and maintenace in UTG is a continuous process, and the content available here is updated frequently.

The resources 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for those that are looking for identifiers that may have been published in the past in HL7 Standards, but have been superceded since that time.
