This Code system is referenced in the content logical definition of the following value sets:


SpecializesThe 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.Coding
GeneralizesInverse of Specializes. Only included as a derived relationship.Coding
internalIdhttp://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-idThe internal identifier for the concept in the HL7 Access database repository.code
notSelectablehttp://hl7.org/fhir/concept-properties#notSelectableIndicates that the code is abstract - only intended to be used as a selector for other conceptsboolean
statushttp://hl7.org/fhir/concept-properties#statusA property that indicates the status of the concept. One of active, experimental, deprecated, or retired.code
deprecationDatehttp://hl7.org/fhir/concept-properties#deprecationDateThe date at which a concept was deprecated. Concepts that are deprecated but not inactive can still be used, but their use is discouraged.dateTime
synonymCodehttp://hl7.org/fhir/concept-properties#synonymAn additional concept code that was also attributed to a conceptcode
subsumedByhttp://hl7.org/fhir/concept-properties#parentThe concept code of a parent conceptcode

This code system http://terminology.hl7.org/CodeSystem/v3-CalendarCycle defines the following codes:
