This page is part of the FHIR Core Extensions Registry (v1.0.0: Releases) based on FHIR v5.0.0. This is the current published version in its permanent home (it will always be available at this URL). For a full list of available versions, see the Directory of published versions 
This table lists extensions for the CodeSystem resource defined in association with the core specification. For background information, see
Extensibility.
Additional extensions may be found in published
Implementation Guides and in the
Conformance resource registry .
