  FHIR US Core → C-CDA Mapping
  While multiple vendors participated in CDA → FHIR mappings at a connectathon, only a single vendor (Cerner/Oracle) has participated in the FHIR → CDA mapping. We welcome feedback on these mappings which represent less than a multi-vendor consensus at this time.
This page provides a mapping from FHIR to CDA. For the CDA to FHIR mapping, please refer to Patient CDA → FHIR. For guidance on how to read the table below, see Reading the C-CDA ↔ FHIR Mapping Pages
