Got an Out-of-Network Bill? Here's How to Fight It
Out-of-network charges are the most common source of surprise medical bills. Federal law now limits many of them — here's when you're protected and what to do.
Out-of-network billing is one of the most frustrating experiences in American healthcare. You go to an in-network hospital for surgery, choose an in-network surgeon — and then get a separate bill for thousands of dollars from an anesthesiologist or assistant surgeon you never met and never chose. Until 2022, this was legal everywhere. Under the No Surprises Act, much of it isn't anymore.
When Are You Protected from Out-of-Network Bills?
Protected situations:
- Emergency care — any emergency room visit at any hospital, regardless of whether it's in your network. Your cost is capped at your in-network cost-sharing.
- Out-of-network providers at in-network facilities — if you went to an in-network hospital and a provider treated you without your knowledge or meaningful choice (anesthesiologist, radiologist, hospitalist, assistant surgeon), they cannot balance bill you.
- Air ambulance — out-of-network air ambulance companies are banned from balance billing.
Not protected (you chose out-of-network):
- You specifically chose an out-of-network provider for a non-emergency procedure and signed a consent form acknowledging the out-of-network status and cost
- The consent form was signed at least 72 hours before the service (or same-day for same-day appointments)
The Consent Form Loophole
Some providers try to get patients to sign consent forms waiving their No Surprises Act rights. This is only valid for certain non-emergency situations and requires meaningful notice — a form buried in admission paperwork, signed in an emergency or urgent situation, is unlikely to constitute valid consent. If you signed something during an emergency admission or under pressure, you may still be protected.
How to Dispute an Out-of-Network Bill Under the No Surprises Act
- Review your Explanation of Benefits (EOB). Your insurer should have already processed the claim at in-network rates. If not, call and tell them the charge is covered by the No Surprises Act.
- Contact the provider in writing. Send a letter citing the No Surprises Act and stating you are only liable for your in-network cost-sharing. Send certified mail.
- File a complaint. If the provider continues to pursue the balance, file a complaint at the CMS No Surprises Help Desk (1-800-985-3059 or cms.gov/nosurprises). Providers face fines up to $10,000 per violation.
- Contact your state's insurance department. Many states have additional surprise billing protections on top of federal law.
What About Ground Ambulance Bills?
Ground ambulance is the biggest gap in the No Surprises Act — it's explicitly excluded. Ground ambulance balance billing is still legal in most states (though some states have their own laws). This is being addressed through ongoing federal rulemaking. Check your state's specific rules.
If you received an out-of-network bill for emergency care or for providers you didn't choose, federal law is almost certainly on your side. The dispute process exists and has real teeth — providers face significant penalties for ignoring it.
