What the No Surprises Act Means for Your Medical Bills

The No Surprises Act protects patients from unexpected and often very large medical bills in specific situations. Passed in 2020 and fully in effect in 2026, it bans most balance billing and gives you clear rights when you receive care in emergencies or from out-of-network providers at in-network facilities.

This guide explains exactly what the No Surprises Act covers, what it means for your bills, and the steps you can take if a provider tries to charge you more than your in-network cost-sharing.

Key protections under the No Surprises Act

The law applies in three main situations:

1. Emergency services You cannot be balance billed for emergency care at any hospital or facility, whether in-network or out-of-network. You pay only your normal in-network deductible, copay, or coinsurance. The provider and insurer must settle the rest between themselves.
2. Non-emergency care at in-network facilities If you receive care from an out-of-network provider while at an in-network hospital or facility (for example, an anesthesiologist, radiologist, or assistant surgeon during a planned procedure), you cannot be balance billed. You pay only your in-network cost-sharing amount.
3. Air ambulance services Air ambulance providers cannot balance bill you. You pay only in-network rates even if the air ambulance is out-of-network.

In all these cases, the total amount you owe is limited to what you would pay for in-network care. The provider cannot send you a bill for the difference between their charge and what the insurer paid.

Good Faith Estimate and Patient-Provider Dispute Resolution

If you are uninsured or choose to self-pay, you have the right to request a Good Faith Estimate before a scheduled non-emergency service. The provider must give you a written estimate within one to three business days.

If the final bill exceeds the Good Faith Estimate by $400 or more, you can use the Patient-Provider Dispute Resolution process. Submit the estimate, the bill, provider details, and a $25 non-refundable administrative fee. An independent reviewer decides the appropriate payment amount. If the decision favors you, the fee is typically deducted from what you owe.

What the No Surprises Act does not cover

• In-network care (normal cost-sharing still applies)
• Care you knowingly choose from an out-of-network provider at an out-of-network facility
• Ground ambulance services (still a common source of surprise bills)

Always ask in advance whether everyone involved in your care is in-network.

What to do if you receive a surprise bill

1. Do not pay the balance-billed amount.
2. Contact the provider in writing and explain that the No Surprises Act applies. Include a copy of your EOB or Good Faith Estimate.
3. Send a copy to your insurer.
4. If the provider continues to bill you, file a complaint with the federal No Surprises Help Desk or your state insurance department.
5. For disputes exceeding the $400 threshold, use the Patient-Provider Dispute Resolution process.
