This code system defines the following properties for its concepts

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.
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..
conductible conductible http://terminology.hl7.org/CodeSystem/utg-concept-properties#rim-conductible boolean If true, indicates that ActRelationships or Participations of the specified type (and any specializations thereof) will normally conduct. For more usage information, refer to the Core Principles specification.

If false, indicates the property is a descriptor of the action itself, actual, intended, or potential. Applies to interpretation of attributes and associations with respect to changes in the value of Act.actionNegationInd and Act.moodCode. (See descriptions of these attributes for further discussion.) For example, in an order, the id attribute [isDocumentCharacteristic = true] is an identifier of the record of the order, not an identifier of the intended event. On the other hand, the code attribute [isDocumentCharacteristic = false] describes a characteristic of the intended event.

3     BEN beneficiary

Target on behalf of whom the service happens, but that is not necessarily present in the service. Can occur together with direct target to indicate that a target is both, as in the case where the patient is the indirect beneficiary of a service rendered to a family member, e.g. counseling or given home care instructions. This concept includes a participant, such as a covered party, who derives benefits from a service act covered by a coverage act.

Note that the semantic role of the intended recipient who benefits from the happening denoted by the verb in the clause. Thus, a patient who has no coverage under a policy or program may be a beneficiary of a health service while not being the beneficiary of coverage for that service.
