Calendar cycle identifiers

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


This code system defines the following properties for its concepts

SpecializesCodingThe 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.
GeneralizesCodingInverse of Specializes. Only included as a derived relationship.
internalIdhttp://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-idcodeThe internal identifier for the concept in the HL7 Access database repository.
notSelectablehttp://hl7.org/fhir/concept-properties#notSelectablebooleanIndicates that the code is abstract - only intended to be used as a selector for other concepts
statushttp://hl7.org/fhir/concept-properties#statuscodeA property that indicates the status of the concept. One of active, experimental, deprecated, or retired.
deprecationDatehttp://hl7.org/fhir/concept-properties#deprecationDatedateTimeThe date at which a concept was deprecated. Concepts that are deprecated but not inactive can still be used, but their use is discouraged.
synonymCodehttp://hl7.org/fhir/concept-properties#synonymcodeAn additional concept code that was also attributed to a concept
subsumedByhttp://hl7.org/fhir/concept-properties#parentcodeThe concept code of a parent concept


This case-sensitive code system http://terminology.hl7.org/CodeSystem/v3-CalendarCycle defines the following codes in a Is-A heirarchy:
