Surprise Medical Bills and Your Protections Under Federal Law
Federal rules now protect most people with health coverage from surprise out-of-network bills for emergency care and for certain care at in-network facilities. Here's what's covered, what isn't, and what to do with a bill that looks wrong.
A "surprise bill" usually happens when you receive care from an out-of-network provider you didn't choose, such as an emergency room doctor, or an anesthesiologist at an in-network hospital, and then get billed the difference between the provider's charge and what your plan paid. Federal law known as the No Surprises Act, effective in 2022, limits many of these bills.
The short version
- For most people with private health coverage, you generally can't be balance billed for emergency services, even from out-of-network providers or facilities.
- You generally can't be balance billed by certain out-of-network providers at in-network facilities for non-emergency care, such as anesthesiology, radiology, and pathology, unless you validly consented in advance where allowed.
- Air ambulance services are covered by these protections; ground ambulance generally isn't under the federal law, though some states protect it.
- People who are uninsured or self-paying can request a good faith estimate and may be able to dispute bills far above it.
- Many states have their own surprise billing laws that may add protections.
What's protected
| Situation | Federal protection |
|---|---|
| Emergency care at an out-of-network hospital | Cost sharing limited to in-network levels; no balance billing |
| Out-of-network emergency physician | Same |
| Anesthesiologist at an in-network hospital | Generally protected from balance billing |
| Air ambulance | Protected |
| Ground ambulance | Generally not under federal law; check state law |
| You knowingly choose an out-of-network provider and sign a valid consent | Protections may not apply where consent is allowed |
How it changes the bill
A hypothetical emergency visit at an out-of-network hospital:

| What you might owe | |
|---|---|
| Without protection | $3,600 |
| With federal protection | $600 |
If you're uninsured or self-pay
Providers generally must give a good faith estimate of expected charges when you schedule care or ask. If the final bill is substantially higher than the estimate, a patient-provider dispute resolution process may be available, within a deadline after billing.
What to do with a surprise bill
- Compare it with your Explanation of Benefits.
- Check whether the service falls under federal or state protections.
- Call the provider and the plan; ask them to reprocess if protections apply.
- Don't pay the disputed balance while it's being resolved, if possible, and keep records.
- Contact the federal help line listed on official consumer pages, or your state insurance department.

The takeaway
Federal law now blocks many surprise out-of-network bills for emergency care and certain care at in-network facilities. Know the protections, compare bills with your plan statements, and push back when a bill looks like one the law prohibits.
