C-CDA on FHIR
1.2.0 - STU 1 United States of America flag

C-CDA on FHIR, published by HL7 International / Cross-Group Projects. This guide is not an authorized publication; it is the continuous build for version 1.2.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/ccda-on-fhir/ and changes regularly. See the Directory of published versions

Resource Profile: Diagnostic Imaging Report

Official URL: http://hl7.org/fhir/us/ccda/StructureDefinition/Diagnostic-Imaging-Report Version: 1.2.0
Active as of 2024-03-12 Computable Name: DiagnosticImagingReport

A Diagnostic Imaging Report (DIR) is a document that contains a consulting specialist’s interpretation of image data. It conveys the interpretation to the referring (ordering) physician and becomes part of the patient’s medical record. It is for use in Radiology, Endoscopy, Cardiology, and other imaging specialties. Note: this document type overlaps with the FHIR DiagnosticReport resource. Most use cases will want to use the specific resource type, but this document type is still useful for CDA to FHIR conversion and other such use cases.

2024 Publication of C-CDA ↔ FHIR US Core Mapping

The current release of this IG adds relevant mapping content from C-CDA ↔ FHIR mapping project which was related to the original C-CDA on FHIR work. These mappings are included under the "Mapping" heading and will undergo future updates for additional content.
