The No Surprises Act: What It Means for Your Medical Bills

Surprise medical bills — unexpected charges from out-of-network providers you did not choose and often did not know were treating you — have cost Americans hundreds of millions of dollars a year. The No Surprises Act (NSA), which took effect January 1, 2022, is the most significant federal consumer protection against surprise billing in American healthcare history. Codified at 42 U.S.C. § 300gg-111, the law creates enforceable rights that patients can invoke to eliminate or reduce unexpected medical charges.

Why Surprise Bills Arrive Despite the No Surprises Act

Emergency care processed at out-of-network rates. Insurers sometimes apply out-of-network cost-sharing to emergency visits, contrary to the NSA's mandate. Under the law, emergency services must be covered as if the provider were in-network, regardless of the actual network status of the ER, the emergency physicians, or any providers involved in stabilization care.

Out-of-network ancillary provider billing. At in-network hospitals and surgical centers, out-of-network anesthesiologists, radiologists, pathologists, hospitalists, and assistant surgeons cannot balance bill you beyond your in-network cost-sharing. This is the classic surprise bill scenario — and it is prohibited under 42 U.S.C. § 300gg-111(b).

Air ambulance out-of-network charges. Out-of-network air ambulance providers are prohibited from billing you more than your in-network cost-sharing amount. If you received an air ambulance bill that exceeds this amount and you did not sign a valid advance consent, the provider is likely violating the NSA.

Improper consent waivers. Providers sometimes present patients with consent forms for out-of-network charges. These waivers are only valid under strict conditions: 72 hours advance notice, written disclosure of the provider's out-of-network status, a Good Faith Estimate of charges, and the patient's right to seek an in-network alternative. In emergency situations — and for anesthesiologists, radiologists, pathologists, and neonatologists — the NSA explicitly prohibits consent waivers.

Good Faith Estimate violations. For uninsured and self-pay patients, providers must give a Good Faith Estimate before scheduled services. If your bill exceeds the GFE by more than $400, you can dispute it through the Patient-Provider Dispute Resolution process.

How to Dispute a Surprise Bill Under the No Surprises Act

Step 1: Confirm the NSA Applies to Your Situation

The NSA covers three specific scenarios: (1) emergency services at any hospital or emergency facility; (2) non-emergency services at an in-network facility by an out-of-network provider you did not choose (without valid advance consent); (3) out-of-network air ambulance services. If your situation matches one of these, the provider cannot legally balance bill you.

Step 2: Check Your EOB)" class="auto-link">Explanation of Benefits

Review your EOB from your insurer. Your cost-sharing should be calculated at in-network rates. If the EOB shows out-of-network cost-sharing applied to an NSA-protected service, contact your insurer and request reprocessing, explicitly citing 42 U.S.C. § 300gg-111.

Step 3: Contact the Provider's Billing Department

Call the billing department and state: "This charge is subject to the No Surprises Act, which prohibits balance billing for this service. I owe only my in-network cost-sharing amount. Please adjust the bill accordingly." Request written confirmation that the bill will be corrected.

Step 4: File a Complaint with the CMS No Surprises Help Desk

If the provider or insurer does not comply, file a complaint at 1-800-985-3059 or through the CMS online portal. CMS investigates NSA violations. Providers who repeatedly violate the law face civil monetary penalties. State insurance departments also investigate surprise billing violations and may impose additional penalties under state law.

Step 5: If You Are Uninsured or Self-Pay, Use the PPDR Process

If your final bill exceeds the Good Faith Estimate by $400 or more, initiate the Patient-Provider Dispute Resolution process through CMS within 120 days of receiving the final bill. The dispute is resolved by an independent PPDR entity, whose decision is binding on the provider.

Step 6: Escalate to External Independent Review: Complete Guide" class="auto-link">External Review if the Insurer Misprocessed Your Claim

If the dispute involves your insurer misapplying the NSA — for example, applying out-of-network cost-sharing to an NSA-protected service — file a formal insurance appeal citing the NSA violation and request external review under ACA Section 2719. File a concurrent state insurance department complaint.

What to Include in Your NSA Dispute

• Your EOB from the insurer showing how cost-sharing was calculated
• Documentation that you did not sign a valid advance consent for out-of-network charges
• Emergency department records if the emergency services provision applies
• Any Good Faith Estimate provided and the comparison to the actual final bill
