Properties

This code system defines the following properties for its concepts

NameCodeURITypeDescriptionValue Set
dataType dataType http://hl7.org/fhir/concept-properties#dataType code data type of property value
Status status http://hl7.org/fhir/concept-properties#status code A code that indicates the status of the concept. Typical values are active, experimental, deprecated, and retired Property Type

Concepts

This case-sensitive code system http://hl7.org/fhir/concept-properties defines the following codes:

CodeDisplayDefinitiondataTypeStatusCopy
status Status

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

 code btn btn
inactive Inactive

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

 boolean btn btn
effectiveDate effectiveDate

The date at which the concept status was last changed

 dateTime btn btn
deprecated Deprecated

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. This property is itself deprecated due to potential confusion with status - use deprecationDate instead

 dateTime deprecated btn btn
deprecationDate Deprecation 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

 dateTime btn btn
retirementDate Retirement Date

The date at which a concept was retired

 dateTime btn btn
notSelectable Not 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, default value is false

 boolean btn btn
parent Parent

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

 code btn btn
child Child

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

 code btn btn
partOf Part 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

 code btn btn
synonym Synonym

This property contains an alternative code that may be used to identify this concept instead of the primary code. Synonyms should not be used due to the operational complexity they introduce - see alternateCode

 code deprecated btn btn
alternateCode Alternate Code

This property contains the code for another representation of this concept, with the same real-world meaning, in this code system.

 code btn btn
comment Comment

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

 string btn btn
itemWeight itemWeight

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

 decimal btn btn
order Order

Order of the concept amongst sibling concepts as a decimal value

 decimal btn btn
definition Definition

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

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
Source The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
