HL7 C-CDA 2.1 - FHIR R4 Map Inventory:C-CDA R2.1/Companion Guide R2 (USCDI Scoped) - FHIR R4 US Core 3.2.0 FHIR R4 US Core 3.2.0 (USCDI Scoped)- C-CDA R2.1/Companion Guide R2
This project will establish definitive HL7 mapping guidance for C-CDA to FHIR and FHIR to C-CDA using the document types in C-CDA R2.1 plus C-CDA Companion Guide R2 referenced/implied in the 2015 Certification Edition Cures Update and USCDI v1 Clinical Notes data class: CCD, Discharge Summary, Referral Note, Consultation Note, Procedure Note, History and Physical, and Progress Note document types.
The project will align wherever possible with the v2-FHIR mapping approach (and vice versa) to enable access to cross-paradigm maps consistently from/to v2, C-CDA, and FHIR contexts. |
