Da Vinci PAS

Da Vinci PAS (Prior Authorization Support) is the HL7 implementation guide for sending a prior authorisation request from a provider system to a health plan as a FHIR Bundle built around a Claim, and getting the decision back as a ClaimResponse.

It is designed to work with the Da Vinci CRD and DTR guides, which find out whether authorisation is needed and gather the documentation, and it describes how the request maps to the X12 278 transaction where that is required.
