Surprise out-of-network bill? Know your No Surprises Act rights
If your surprise bill is from emergency care, an out-of-network provider at an in-network facility, or an air ambulance, the federal No Surprises Act generally limits you to in-network cost-sharing — and you can dispute the balance. Ground ambulance bills are not covered by the federal law.
"Balance billing" is when an out-of-network provider bills you for the gap between their charge and what your insurer paid. Since January 2022, the No Surprises Act has banned that in the most common surprise situations.
The hard part is that providers still send the bill. Knowing exactly what is protected is what lets you push it back.
What the No Surprises Act covers
Emergency services — including from out-of-network hospitals and providers.
Non-emergency services from out-of-network providers at an in-network facility (think anesthesiologists, radiologists, pathologists, assistant surgeons you did not choose).
Air ambulance services from out-of-network providers.
In these cases you owe only your in-network cost-sharing; the provider cannot balance-bill you for the rest.
What it does NOT cover
Ground ambulances — the biggest gap. They can still bill out-of-network rates unless your state has its own protection.
Care you knowingly chose out-of-network after getting proper notice and signing a consent (in certain non-emergency cases).
If you’re uninsured or self-pay: the Good Faith Estimate
You are entitled to a written Good Faith Estimate of expected charges before scheduled care.
If your final bill is at least $400 more than the estimate for a given provider, you can use the federal patient-provider dispute resolution process — start within 120 days of the bill.
Step by step
Confirm it’s a protected surprise bill
Was it emergency care, an out-of-network provider at an in-network facility, or an air ambulance? If so, you are likely protected.
Compare it to your EOB
Check your insurer’s Explanation of Benefits. You should only owe in-network cost-sharing for protected services.
Tell the provider it violates the No Surprises Act
Ask them in writing to rebill at the protected in-network amount and remove the balance.
Escalate if they won’t fix it
File a complaint with the federal No Surprises Help Desk (1-800-985-3059), and your state insurance regulator if applicable.

FAQ
Are ground ambulance bills covered?
No — the federal No Surprises Act does not cover ground ambulances. Some states have their own protections, but federally they can still balance-bill. See our ambulance-bill guide for what to do anyway.
What if the emergency happened out of state?
Emergency protections still apply. The No Surprises Act’s emergency provisions are not limited to your home state.
I’m uninsured — do I have any protection?
Yes. You’re entitled to a Good Faith Estimate, and if the final bill exceeds it by $400 or more for a provider, you can dispute it through the federal patient-provider dispute resolution process within 120 days.
