HL7 FHIR® Implementation Guide: C-CDA on FHIR, Edition 2 - US Realm

DESCRIPTION

Consolidated CDA (C-CDA) is one of the most widely implemented implementation guides for CDA and covers a significant scope of clinical care. Its target of the ‘common/essential’ elements of healthcare is closely aligned with FHIR’s focus on the ‘80%’. There is significant interest in industry and government in the ability to interoperate between CDA and FHIR and C-CDA is a logical starting point. Implementers and regulators have both expressed an interest in the ability to map between FHIR and C-CDA.

This Implementation Guide (IG) defines a set of maps to guide transformation of C-CDA instances into FHIR and vice-versa. The maps cover the twelve domains, and they are being expanded to cover the USCDI domains.
