Aetna Prior Authorization FHIR API is one of 7 APIs that [Aetna](https://apis.io/providers/aetna/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include FHIR, Prior Authorization, Da Vinci, CDS Hooks, and CRD. The published artifact set on APIs.io includes API documentation and an API reference.

Da Vinci prior-authorization surface built for CMS-0057-F: Coverage Requirements Discovery (STU 2.1) at /coveragerequirementsdiscovery/v1/cds-services/{id} supporting the order-sign, order-dispatch and appointment-book CDS Hooks; Prior Authorization Support (STU 2.1) at /priorauthorizationsupport/v1/Claim/$submit and /$inquire; and Clinical Data Exchange (CDex STU 2.1.0) at /clinicaldataexchange/v1/$submit-attachment. Aetna states that Meritain members, Medicaid members, pharmacy prior authorization and SNOMED procedure codes are not supported. Production traffic for these products moved to the apix.cvshealth.com host on 2026-03-04. Every spec document for this API returned HTTP 403 when this repo was harvested, so no machine-readable contract for it is held here.
