Properties

This code system defines the following properties for its concepts

Code

URI

Type

Description

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

Coding

Inverse of Specializes. Only included as a derived relationship.

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

http://hl7.org/fhir/concept-properties#status

code

Designation of a concept's state. Normally is not populated unless the state is retired.

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

Code	Display	Definition	internalId	status	synonymCode
ISS	Issued by System	Description: The identifier was issued by the system responsible for constructing the instance.	22614	active
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.	22653	active
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.	22652	active	VER
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.	22652	retired	VRF
