Properties

This code system defines the following properties for its concepts

Name

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

status

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

code

Designation 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 hierarchy:

Code	Display	Definition	internalId	Status
BT	Broader Than	The 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.	11054	active
E	Exact	The two concepts have identical meaning.	11053	active
NT	Narrower Than	The 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.	11055	active
