** MISSING DESCRIPTION **

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

Properties

This code system defines the following properties for its concepts

CodeURITypeDescription
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#statuscodeDesignation of a concept's state. Normally is not populated unless the state is retired.

Concepts

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

1A intersectForm the intersection with the value.17419active
1H convex hullForm the convex hull with the value. The convex hull is defined over ordered domains and is the smallest contiguous superset (interval) that of all the operand sets.17420active
1P periodic hullForm the periodic hull with the value. The periodic hull is defined over ordered domains and is the periodic set that contains all contiguous supersets of pairs of intervals generated by the operand periodic intervals.17421active
