Nobody who dials 911 gets to pick the ambulance. A dispatcher sends the closest crew. Whether that crew has a contract with your health plan never comes up, and you're in no shape to ask.
For most of the rest of an emergency, that question stopped mattering on January 1, 2022, when the federal No Surprises Act took effect. Land in an out-of-network ER, and for most emergency services the hospital can no longer send you the out-of-network "balance bill" for whatever your plan didn't pay. The same goes if the hospital is in your network but a doctor working there isn't. It even covers air ambulance flights. You pay what you'd pay in network: your normal copay, deductible or coinsurance. Anything past that gets settled between the provider and your insurer, and you're not part of that fight.
Ground ambulances were left out. Congress couldn't agree on how to handle them, so it set up an advisory committee and moved on, and as of September 2026 the federal rule hasn't changed. That makes the ride to the hospital the one part of a typical emergency that can still produce a surprise bill under federal law.
How often does it happen? Researchers at the Peterson-KFF Health System Tracker went through claims from large employer plans. Of the emergency ground ambulance rides, 51% included an out-of-network charge that could turn into a surprise bill. Non-emergency rides weren't much better, at 39%. About 3 million privately insured people arrive at an emergency room by ambulance each year, and by the researchers' estimate roughly 1.5 million of them were exposed.
51%. About half of emergency ground ambulance rides for privately insured patients carried an out-of-network charge, according to a Peterson-KFF analysis of 2018 insurance claims.
Those claims date from 2018, before the newer state laws. Read the numbers as the size of the problem, not a current count.
Which bills are protected, and which aren't
Find your situation below. The sorting follows guidance from the Centers for Medicare & Medicaid Services.
| Situation | Federal protection | What you can be charged |
|---|---|---|
| Emergency room visit at an out-of-network hospital | Yes | In-network cost sharing only |
| Out-of-network anesthesiologist, radiologist or pathologist at an in-network hospital | Yes | In-network cost sharing only |
| Air ambulance from an out-of-network company | Yes | In-network cost sharing only |
| Out-of-network surgeon you chose for planned care, after signing a consent form | No, you waived it | Out-of-network rates |
| Ground ambulance, out of network | No | Whatever your plan doesn't pay, unless state law says otherwise |
| Care at an out-of-network facility you chose for a non-emergency | No | Out-of-network rates |
Does your plan count? If you get coverage through work, or you bought it yourself (marketplace plans included), yes. Short-term plans don't, and neither do dental-only or vision-only plans or health care sharing ministries. People on Medicare, Medicaid, TRICARE or veterans' care already had their own rules against balance billing before this law came along.
Got a bill that falls in one of the "Yes" rows and asks for more than your in-network share? You don't owe the extra. The provider isn't allowed to bill it. The No Surprises Help Desk at 1-800-985-3059 takes complaints and can tell you if a specific bill is covered.
How does an ambulance bill get so big?
Take a made-up ride. It lasts 11 minutes, and the ambulance company bills $2,700. Your plan decides a reasonable price is $900 and pays 80% of that, or $720. With an in-network provider you'd owe the other $180, and that would be that.
This company has no contract with your plan, though, so it isn't bound by the $900 figure. It bills you the $180 plus the $1,800 your insurer didn't recognize. Total: $1,980, for a ride you couldn't shop for. Under federal law, that bill is legal.
Your own bill could land higher or lower. For a sense of scale, the average ground ambulance bill for people with commercial insurance was $1,093 in 2021. That's a Health Care Cost Institute number, as cited by Georgetown University's Center on Health Insurance Reforms.
Who's sending these bills? Often not a company at all. In the Peterson-KFF data, fire departments and other government agencies ran 62% of emergency ground rides. A public agency often has no contract with any private insurer, so nearly every ride it runs is out of network.
The advisory committee did finish its homework. Its 2024 recommendation was to ban balance bills for ground ambulance rides and cap what the patient pays at $100 or 10% of the rate, whichever is less. Congress hasn't turned that into law.
Where state laws fill part of the gap
Some states didn't wait. By March 2026, 22 of them had some protection against ground ambulance surprise bills, and five of those laws were brand new (Georgetown's count). States split on which ambulance services are covered, how the payment rate gets set and whether non-emergency rides count.
Then comes the wrinkle that trips people up: a state law only helps if your plan answers to the state. Mostly that means plans you buy yourself and "fully insured" employer plans. Most large employers self-fund their health plans, and those answer to federal law instead. Washington, for one, bans ground ambulance balance billing for state-regulated plans and lets self-funded employer plans opt in, which means that if you work for a company that hasn't opted in, the state law doesn't help you.
So an ambulance bill raises two questions. Does your state have a law? And is your plan the kind that law covers? Those two answers decide which of the steps below will work for you.
