Normative Candidate Note: This page is candidate normative content for R4 in the Conformance Package. Once normative, it will lose it's Maturity Level, and breaking changes will no longer be made.

This is a value set defined by the FHIR project.

Expansion based on version 3.2.0

All codes from system

requiredRequiredTo be conformant, the concept in this element SHALL be from the specified value set
extensibleExtensibleTo be conformant, the concept in this element SHALL be from the specified value set if any of the codes within the value set can apply to the concept being communicated. If the value set does not cover the concept (based on human review), alternate codings (or, data type allowing, text) may be included instead.
preferredPreferredInstances are encouraged to draw from the specified codes for interoperability purposes but are not required to do so to be considered conformant.
exampleExampleInstances are not expected or even encouraged to draw from the specified value set. The value set merely provides examples of the types of concepts intended to be included.

Explanation of the columns that may appear on this page:

LvlA few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organise codes for user convenience, but may follow code system hierarchy - 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
