Properties

This code system defines the following properties for its concepts

NameCodeURITypeDescription
Specializes Specializes Coding The child code is a more narrow version of the concept represented by the parent code. I.e. Every child concept is also a valid parent concept. Used to allow determination of subsumption. Must be transitive, irreflexive, antisymmetric.
Generalizes Generalizes Coding Inverse of Specializes. Only included as a derived relationship.
internalId internalId http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id code The internal identifier for the concept in the HL7 Access database repository.
Status status http://hl7.org/fhir/concept-properties#status code Designation of a concept's state. Normally is not populated unless the state is retired.
