Extension: Advance Directive Absent Reason

Official URL: http://hl7.org/fhir/us/pacio-adi/StructureDefinition/adi-documentation-absent-reason Version: 2.0.0-ballot
Standards status: Trial-use Maturity Level: 2 Computable Name: ADIDocumentationAbsentReason
Other Identifiers: OID:2.16.840.1.113883.4.642.40.68.42.57

The Advance Directive Absent Reason Extension specifies why an advance directive document does not exist or was not completed. This differs from dataAbsentReason which is completed when a field has no value. Rather, the USCoreObservationADIDocumentationProfile from which this IG's ADI-DocumentationObservation profile derives from has a Yes/No answer and hence cannot use dataAbsentReason due to the FHIR obs-6 invariant which states that the element will have a value only if Observation.value[x] is missing.
