CodeURLTypeDescription
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.

This code system http://terminology.hl7.org/CodeSystem/v3-ActExposureLevelCode defines the following codes:

1_ActExposureLevelCode ActExposureLevelCodeA qualitative measure of the degree of exposure to the causative agent. This includes concepts such as "low", "medium" and "high". This quantifies how the quantity that was available to be administered to the target differs from typical or background levels of the substance.22372trueactive
2  HIGH high**Description:** Exposure to an agent at a relatively high level above background.22373active
2  LOW low**Description:** Exposure to an agent at a relatively low level above background.22374active
