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.
statushttp://hl7.org/fhir/concept-properties#statuscodeDesignation of a concept's state. Normally is not populated unless the state is retired.
synonymCodehttp://hl7.org/fhir/concept-properties#synonymcodeAn additional concept code that was also attributed to a concept

Concepts

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

ISS Issued by System**Description:** The identifier was issued by the system responsible for constructing the instance.22614active
UNV Unverified by system**Description:** The identifier was provided to the system that constructed the instance, but has not been verified. e.g. a Drivers license entered manually into a system by a user.22653active
VRF Verified by system**Description:** The identifier was not issued by the system responsible for constructing the instance, but the system that captured the id has verified the identifier with the issuing authority, or with another system that has verified the identifier.22652activeVER
VER Verified by system**Description:** The identifier was not issued by the system responsible for constructing the instance, but the system that captured the id has verified the identifier with the issuing authority, or with another system that has verified the identifier.22652retiredVRF
