State balance billing bans extend protections beyond the federal No Surprises Act, which took effect on January 1, 2022, to cover additional medical scenarios. The federal law bans balance billing for emergency care and out-of-network services provided at in-network facilities, but gaps remain. Eighteen states have enacted comprehensive protections that go further, while fifteen have partial laws and seventeen have no state-specific safeguards at all, creating a fragmented landscape that depends heavily on where you live. This variation matters because it determines whether you can be billed for services you didn't know were out-of-network—and how much recourse you have if it happens.

What State Laws Add Beyond Federal Protection
The federal No Surprises Act covers specific scenarios: emergency care and certain services at in-network facilities, like anesthesia or radiology performed by out-of-network providers. States with comprehensive protections—including California, Connecticut, Florida, Illinois, Maryland, and New York—extend these safeguards to cover additional scenarios and providers. These stronger state laws often broaden protections to cover non-emergency situations, expand the definition of what counts as a covered service, and provide additional remedies for patients.
Some states cap how much patients can be charged out-of-pocket in these situations. The effect is that residents of these states receive more comprehensive protection against surprise bills than the federal minimum allows.
Where You Stand: The State-by-State Map
Eighteen states have comprehensive balance billing protections, fifteen provide partial coverage, and seventeen have none, according to the Commonwealth Fund. If you live in Alaska, Hawaii, Utah, North Dakota, South Dakota, or Alabama, your only protection is the federal No Surprises Act.
These residents rely entirely on federal coverage for emergency care and in-network facility services. The strongest protections cluster in states like California and New York, where residents benefit from decades of consumer protection law. Other states offer limited protections—for example, covering only specific scenarios like emergency services—leaving gaps in coverage. If you're moving or planning elective surgery out of state, verify what protections apply in that state before scheduling.
The Ground Ambulance Gap That States Are Filling
One of the largest gaps in federal protection is ground ambulances. The No Surprises Act excludes ground ambulance services from its balance billing ban, unlike air ambulances. This matters because approximately 50% of emergency ground ambulance rides and 39% of non-emergency rides result in out-of-network charges for privately insured patients.
States have begun addressing this. As of 2026, 24 states have enacted ground ambulance balance billing protections for fully insured plans, with states like New Hampshire enacting new ambulance protections during 2026. If you live in a state with this protection and an ambulance ride is out-of-network, you should be charged only your in-network cost-sharing amount—not the full difference between the ambulance company's charge and what insurance paid.
What Balance Billing Protections Still Don't Cover
Even with state laws in place, balance billing can occur in situations outside the protections. Many state ambulance laws apply only to fully insured commercial plans, not self-insured employer plans. Certain providers—like independent laboratories or imaging centers that aren't technically part of a hospital—may not be covered. Non-emergency care at out-of-network providers still typically leaves you liable for the difference.
Insurance plans also matter. Protections vary for different plan types, and some coverage gaps exist by design. For example, if you knowingly choose an out-of-network provider and sign an agreement accepting out-of-network costs, protections may not apply. Always verify your plan's coverage before scheduling care, and ask specifically whether all providers involved in a procedure are in-network.
What to Do if You Receive a Balance Bill
If you receive a balance bill you believe violates your state's protections or the federal No Surprises Act, start by reviewing your insurance explanation of benefits and the bill itself to confirm the service and provider involved. Contact your insurance company to dispute the bill and cite the specific federal or state law that should apply.
Many insurers have departments dedicated to handling No Surprises Act disputes. If the insurer doesn't resolve it, file a complaint with your state's insurance commissioner or attorney general's office. The Consumer Financial Protection Bureau also accepts complaints about surprise medical bills. Document everything—the service date, the providers involved, the amounts charged and paid, and all communication with your insurer. Do not ignore the bill or assume it will go away; state and federal laws now require resolution in your favor.
Frequently Asked Questions
Does the No Surprises Act protect me from all balance bills?
No. The federal law covers emergency care and certain services at in-network facilities, but excludes ground ambulances and many non-emergency situations. State laws fill some gaps.
What should I do before scheduling surgery to avoid a balance bill?
Call your insurance company and verify that all providers involved—the surgeon, anesthesiologist, facility, and imaging services—are in-network. Get confirmation in writing. Ask your surgery center to confirm each provider's network status separately.
If my state has no balance billing law, am I unprotected?
You have federal protection under the No Surprises Act for emergency care and in-network facility services. For other situations, you may be unprotected, which is why confirming in-network status before care is essential.
Can I negotiate a balance bill down?
Many providers will negotiate or reduce balance bills if you contact them directly. You can also dispute the bill through your insurance company or file a complaint with your state's insurance commissioner.
