Air ambulance balance billing
Air ambulance services are covered under the federal No Surprises Act, which prohibits balance billing for both in-network and out-of-network air ambulance. Patients who receive a balance bill from an air ambulance provider after January 1, 2022 are protected by federal law and the dispute moves to federal independent dispute resolution.
What gets denied
- Out-of-network helicopter or fixed-wing air ambulance
- Plan pays only a portion of the air ambulance charge
- Balance bills sent directly to the patient
- Medical-necessity denial of air transport (vs. ground)
Common denial reasons
- Plan claims air transport was not medically necessary
- Air ambulance is out-of-network
- Plan paid only its 'allowed amount' and the provider is balance-billing the difference
- Plan claims documentation of medical urgency is insufficient
How we approach the appeal
Invoke the No Surprises Act air ambulance protections directly — balance billing for covered air ambulance is prohibited regardless of network status. The cost-sharing must be in-network equivalent. File a complaint with the federal No Surprises Help Desk (CMS) if the provider continues to balance bill. For medical-necessity denials, attach the dispatching physician's or first-responder's documentation of the urgent need for air transport (distance, ground transport time, clinical status).
Internal appeal: 180 days. NSA complaints to CMS can be filed at any time. Provider IDR initiation deadlines are short and provider-driven.
