Vocabulary domain qualifiers are concepts that are used in domain constraints to specify behavior of the new domain.

Code system retired.

This Code system is referenced in the content logical definition of the following value sets:

  • This CodeSystem is not used here; it may be used elsewhere (e.g. specifications and/or implementations that use this content)


This code system defines the following properties for its concepts

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.
notSelectablehttp://hl7.org/fhir/concept-properties#notSelectablebooleanIndicates that the code is abstract - only intended to be used as a selector for other concepts
statushttp://hl7.org/fhir/concept-properties#statuscodeDesignation of a concept's state. Normally is not populated unless the state is retired.
synonymCodehttp://hl7.org/fhir/concept-properties#synonymcodeAn additional concept code that was also attributed to a concept


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

1_Extensibility ExtensibilityThe extensibility of coding determines whether or not extensions are allowed in the domain of a coded attribute.21294trueactive
2  CNE Coded No ExtensionsThe coded attribute allows only concepts from the defined value set. No extensions are allowed.11049active
2  CWE Coded With ExtensionsThe coded attribute allows local codes or user entered text to be sent when the concept that the user would like to express is not a member of the defined value set. If the concept that the user wants to express is represented by a code in the standard value set, the standard code must be sent. The local code can be sent in addition to the standard code if desired. Only if the concept that the user wants to express is NOT represented by a standard code, can a solitary local code be sent.11048active
1_RealmOfUse RealmOfUseThe jurisdiction or realm within which the domain will be used. A realm might be a country, a group of countries, a region of the world, or an organization.21295trueactive
