Why it surfaced
PreauthRail is unusually candid about its limits: 22 payer forms are mapped and tested, but the rail has carried zero live payer transactions so far. It offers a free sandbox and publishes the implementation details, including FHIR Da Vinci PAS, CRD, and DTR support across 52 jurisdictions.
