This Code system is used in the following value sets:

  • ValueSet: DiscriminatorType (How an element value is interpreted when discrimination is evaluated.)

How an element value is interpreted when discrimination is evaluated.


This code system defines the following properties for its concepts

statushttp://hl7.org/fhir/concept-properties#statuscodeA property that indicates the status of the concept. One of active, experimental, deprecated, retired
deprecationDatehttp://hl7.org/fhir/concept-properties#deprecationDatedateTimeThe date at which a concept was deprecated. Concepts that are deprecated but not inactive can still be used, but their use is discouraged


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

CodeDisplayDefinitionDeprecatedStatusDeprecation DateCopy
value ValueThe slices have different values in the nominated element, as determined by the applicable fixed value, pattern, or required ValueSet binding.btn btn
exists ExistsThe 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.btn btn
pattern PatternThe 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'

type TypeThe slices are differentiated by type of the nominated element.btn btn
profile ProfileThe 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.btn btn
position PositionThe 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.btn btn

Explanation of the columns that may appear on this page:

LevelA few code lists that FHIR defines are hierarchical - each code is assigned a level. See Code System for further information.
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe 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
