Extension: MCCoD Onset to Death Interval (Experimental)

Official URL: http://mccod.w3datanet.com/fhir/StructureDefinition/mccod-onset-to-death-interval Version: 0.1.0
Draft as of 2026-05-22 Computable Name: MCCoDOnsetToDeathInterval

The approximate interval between the onset of a condition and the time of death, as estimated by the certifying practitioner. Represented as a free-text string (e.g. "2 hours", "3 weeks", "5 years") rather than a structured FHIR Duration, because clinical estimates on death certificates are inherently imprecise and do not conform to structured duration semantics. Corresponds to the "Time interval from onset to death" column of the WHO MCCoD Form A, identified by LOINC 69440-6 (Disease onset to death interval).
