Resource Profile: DocumentReference - MDI Report

A reference to a death investigation document, such as an Autopsy Report or Investigator’s Narrative. The content may be included as inline base64 encoded data or be provided by direct reference (e.g., URL). The document type is required and is constrained by US Core to a LOINC value whose SCALE is DOC in the LOINC database or is the HL7 v3 Code System NullFlavor concept ‘unknown’.
