Extension: Code Options

Official URL: http://hl7.org/fhir/StructureDefinition/codeOptions				Version: 5.2.0-ballot
Standards status: Trial-use			Maturity Level: 1	Computable Name: CodeOptions

A logical reference (i.e. a reference to ValueSet.url) to a value set (and optionally a version) that identifies a set of possible coded values for the element. This extension is used to convey a list of candidate codes when there is no formal code in the code system already defined that captures the intended set. For example, the concept of COVID preventative medications can be expressed as a value set because there is no specific code representing that concept.

This extension supports specifying the focus of an activity as a set of possible codes when there is no specific code available that captures the candidate activities. Note that using this extension as a mechanism to establish the extent of an activity is a placeholder and the extension is a candidate for deprecation after the solution for handling this requirement is revisited at a later time.

Constraints

Id	Grade	Path(s)	Details	Requirements
ele-1	error	**ALL** elements	All FHIR elements must have a @value or children : hasValue() or (children().count() > id.count())
ext-1	error	**ALL** extensions	Must have either extensions or value[x], not both : extension.exists() != value.exists()

R4B

The extension is unchanged in R4B

The extension is unchanged in R4

R3

The extension is represented a little differently in R3:

• Map the type canonical to uri on the element Extension.value[x]
• Note: Extensions that have been modified for R3 are still draft while real-world experience is collected
