| Name | Code | URI | Type | Description |
| Specializes | Specializes | | Coding | The 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. |
| Generalizes | Generalizes | | Coding | Inverse of Specializes. Only included as a derived relationship. |
| internalId | internalId | http://terminology.hl7.org/CodeSystem/utg-concept-properties#v3-internal-id | code | The internal identifier for the concept in the HL7 Access database repository. |
| Not Selectable | notSelectable | http://hl7.org/fhir/concept-properties#notSelectable | boolean | Indicates that the code is abstract - only intended to be used as a selector for other concepts |
| Status | status | http://hl7.org/fhir/concept-properties#status | code | Designation of a concept's state. Normally is not populated unless the state is retired. |
| Synonym | synonymCode | http://hl7.org/fhir/concept-properties#synonym | code | An additional concept code that was also attributed to a concept |
