Properties

This code system defines the following properties for its concepts

NameCodeTypeDescription
FHIRdatatype FHIRdatatype string Indicates the FHIR data type associated with the concept.

Concepts

This code system http://hl7.org/fhir/uv/termchangeset/CodeSystem/hl7-defined-property-cs defines the following codes:

CodeDefinitionFHIRdatatype
name The name of the code system string
version The version of the code system used for the look up operation string
display The recommended display for the concept, if one is known string
designation Other designations for the concept string
effectiveTime This is the effectiveTime value from the RF2 concepts file (from the snapshot). dateTime
moduleId The SNOMED CT concept id of the module that the concept belongs to. code
normalForm Generated Necessary Normal Form expression for the provided code or expression, with terms. The normal form expressions are not suitable for use in subsumption testing. string
normalFormTerse Generated Necessary Normal form expression for the provided code or expression, concept ids only. The normal form expressions are not suitable for use in subsumption testing. string
semanticTag The phrase inside the last set of brackets of its Fully Specified Name. code
sufficientlyDefined True if the description logic definition of the concept includes sufficient conditions. This is derived from the definitionStatusId value in the Concept file of the RF2 distribution (i.e. If 900000000000073002 |Sufficiently defined concept definition status| then true). boolean
