This value set contains 13 concepts

SystemCodeDisplay (en)DefinitionstatusJSONXML
http://hl7.org/fhir/concept-properties  statusStatus

A code that indicates the status of the concept. Typical values are active, experimental, deprecated, and retired

http://hl7.org/fhir/concept-properties  inactiveInactive

True if the concept is not considered active - e.g. not a valid concept any more. Property type is boolean, default value is false. Note that the status property may also be used to indicate that a concept is inactive

http://hl7.org/fhir/concept-properties  effectiveDateeffectiveDate

The date at which the concept status was last changed

http://hl7.org/fhir/concept-properties  deprecatedDeprecated

The date at which a concept was deprecated. Concepts that are deprecated but not inactive can still be used, but their use is discouraged, and they should be expected to be made inactive in a future release. Property type is dateTime. Note that the status property may also be used to indicate that a concept is deprecated

deprecated
http://hl7.org/fhir/concept-properties  deprecationDateDeprecation Date

The date at which a concept was deprecated. Concepts that are deprecated but not inactive can still be used, but their use is discouraged, and they should be expected to be made inactive in a future release. Property type is dateTime. Note that the status property may also be used to indicate that a concept is deprecated

http://hl7.org/fhir/concept-properties  retirementDateRetirement Date

The date at which a concept was retired

http://hl7.org/fhir/concept-properties  notSelectableNot Selectable

The concept is not intended to be chosen by the user - only intended to be used as a selector for other concepts. Note, though, that the interpretation of this is highly contextual; all concepts are selectable in some context. Property type is boolean

http://hl7.org/fhir/concept-properties  parentParent

The concept identified in this property is a parent of the concept on which it is a property. The property type will be 'code'. The meaning of 'parent' is defined by the hierarchyMeaning attribute

http://hl7.org/fhir/concept-properties  childChild

The concept identified in this property is a child of the concept on which it is a property. The property type will be 'code'. The meaning of 'child' is defined by the hierarchyMeaning attribute

http://hl7.org/fhir/concept-properties  partOfPart Of

The concept identified in this property (by its code) contains this concept as a component (i.e. a part-of relationship rather than a subsumption relationship such as elbow is part-of arm

http://hl7.org/fhir/concept-properties  synonymSynonym

This property contains an alternative code that may be used to identify this concept instead of the primary code

http://hl7.org/fhir/concept-properties  commentComment

A string that provides additional detail pertinent to the use or understanding of the concept

http://hl7.org/fhir/concept-properties  itemWeightitemWeight

A numeric value that allows the comparison (less than, greater than) or other numerical manipulation of a concept (e.g. Adding up components of a score). Scores are usually a whole number, but occasionally decimals are encountered in scores. In questionnaires, the item weight may be represented using the http://hl7.org/fhir/StructureDefinition/itemWeight extension
