Use this for delegated arrangements, carve-outs, or benefit exclusions that apply only to this facility's contract. The PA resolver consults these as Tier 0 (highest precedence) when a ``ccn`` is supplied to ``/v1/prior-auth/check``. Omit ``payer_slug`` to apply to every payer on the facility's roster. ## OpenAPI ````yaml /docs/openapi.client.json post /v1/facilities/{ccn}/pa-overrides openapi: 3.1.0 info: description: >- Client API for RCIntel.
