FHIR Extensions Pack
5.4.0 - May 2026 International flag

FHIR Extensions Pack, published by HL7 International / FHIR Infrastructure. This guide is not an authorized publication; it is the continuous build for version 5.4.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/fhir-extensions/ and changes regularly. See the Directory of published versions

Extension: Supporting Evidence

Official URL: http://hl7.org/fhir/StructureDefinition/cqf-supportingEvidence		Version: 5.4.0	Highlight text changes?
Standards status: Draft	Maturity Level: 1	Responsible: HL7 International / Clinical Decision Support	Computable Name: SupportingEvidence
Other Identifiers: OID:2.16.840.1.113883.4.642.40.97.42.124

Specifies the result of a supporting evidence expression in the measure population. The result of the expression is represented in an extension, using the same mapping as specified in Using CQL With FHIR, with the exception that tuples and lists are represented in extensions, rather than mapped to the Parameters resource.

This is an draft extension definition; the committee is seeking implementation feedback, and the definition or contents of the extension may change in future versions

Context of Use

This extension may be used on the following element(s)
