Properties

This code system defines the following properties for its concepts

Code

URI

Type

Description

status

http://hl7.org/fhir/concept-properties#status

code

A property that indicates the status of the concept. One of active, experimental, deprecated, retired

deprecationDate

http://hl7.org/fhir/concept-properties#deprecationDate

dateTime

The date at which a concept was deprecated. Concepts that are deprecated but not inactive can still be used, but their use is discouraged

Concepts

This code system http://hl7.org/fhir/discriminator-type defines the following codes:

Code	Display	Definition	Deprecated	Status	Deprecation Date	Copy
value	Value	The slices have different values in the nominated element, as determined by the applicable fixed value, pattern, or required ValueSet binding.
exists	Exists	The slices are differentiated by the presence or absence of the nominated element. There SHALL be no more than two slices. The slices are differentiated by the fact that one must have a max of 0 and the other must have a min of 1 (or more). The order in which the slices are declared doesn't matter.
pattern	Pattern	The slices have different values in the nominated element, as determined by the applicable fixed value, pattern, or required ValueSet binding. This has the same meaning as 'value' and is deprecated.	Deprecated Pattern' is deprecated - it works exactly the same as 'value'	deprecated	2022-08-19
type	Type	The slices are differentiated by type of the nominated element.
profile	Profile	The slices are differentiated by conformance of the nominated element to a specified profile. Note that if the path specifies .resolve() then the profile is the target profile on the reference. In this case, validation by the possible profiles is required to differentiate the slices.
position	Position	The slices are differentiated by their index. This is only possible if all but the last slice have min=max cardinality, and the (optional) last slice contains other undifferentiated elements.

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
