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.

Concepts

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

CodeDisplayDefinitioninternalIdstatus
BT Broader ThanThe first concept is at a more abstract level than the second concept. For example, Hepatitis is broader than Hepatitis A, and endocrine disease is broader than Diabetes Mellitus. Broader than is the opposite of the narrower than relationship.11054active
E ExactThe two concepts have identical meaning.11053active
NT Narrower ThanThe first concept is at a more detailed level than the second concept. For example, Pennicillin G is narrower than Pennicillin, and vellus hair is narrower than hair. Narrower than is the opposite of broader than.11055active
