URL for this extension:

http://hl7.org/fhir/StructureDefinition/codesystem-subsumes

Status: draft. Extension maintained by: HL7

Refers to another code defined within the code system that is also subsumed by this code. I.e. This concept subsumes the referenced concept. Because meaning is inferred from hierarchy as well as definition, the presence of this extension modifies the meaning of the extended concept.

Context of Use: Use on element: CodeSystem.concept
