##  Death Certificate Reference

**Death Certificate Reference** is a profile of the [FHIR STU3 DocumentReference](http://hl7.org/fhir/STU3/documentreference.html) resource. A DocumentReference resource is used to index a document, clinical note, and other binary objects to make them available to a healthcare system. The death certificate is the target document of the death certificate reference. The use case for document reference is the need to maintain document identifiers assigned by interested parties that differ from the identifier assigned by the custodial jurisdictional agency.
