- We will leverage as much of the ongoing work from the O&O HL7v2-to-FHIR initiative mapping project as possible.
- HL7v2.5.1 will be the source data standard which will be mapped to FHIR. While there are other more recent versions of HL7v2, version 2.5.1 is cited for CLIA conformance.

The attached Spreadsheet provides a mapping from Health Plan data sources to the FHIR US Core (R4) Profile:
