Upcoming Breaking Change - Support for deceasedDateTime Field in FHIR Patient Resource

Last updated: 30 Jul 2025

To meet USCDI v3 requirements, Canvas will begin populating the deceasedDateTime field in the FHIR Patient resource starting August 22, 2025.

• If deceasedDateTime is available, it will be returned.
• If not, the existing deceasedBoolean field will continue to be returned.
• Per the FHIR specification, only one of these fields will be present at a time.

Action required: Clients should ensure their systems can consume either deceasedDateTime or deceasedBoolean.
