Implement surprise billing protections for non-emergency services at in-network facilities under the No Surprises Act — detect ancillary provider scenarios and manage patient consent requirements

Verified steps

1. Identify non-emergency services at in-network facilities where a nonparticipating provider rendered care — for example, an out-of-network anesthesiologist, radiologist, or assistant surgeon involved in a scheduled procedure.
2. Determine whether the nonparticipating provider qualifies as an exception: ancillary providers (assistant surgeons, anesthesiologists, hospitalists, and others in the defined ancillary categories) cannot balance bill without an informed consent waiver.
3. If the provider is in a non-ancillary specialty that permits a consent exception, verify that the required notice-and-consent form was provided to the patient at least 72 hours before the scheduled service (or on the day of scheduling if within 72 hours) and that a signed consent was obtained.
4. Adjudicate the claim: if no valid consent was obtained for an ancillary provider, apply the in-network cost-sharing rate and the QPA as the plan payment; if valid consent was obtained for an eligible specialist, apply standard out-of-network processing.
5. Return an explanation to the provider noting the applicable payment rule and informing them of open negotiation and IDR rights if they dispute the allowed amount.
6. Audit the nonparticipating provider's claims periodically to ensure they are not routinely relying on the consent exception for procedures where prior consent is not feasible.
