Medical Billing Error: Surprise Bills, the No Surprises Act, and Disputing a Charge

Since January 1, 2022, the federal No Surprises Act protects people with group or individual health coverage from many surprise medical bills: emergency services (even at an out-of-network facility), non-emergency services from an out-of-network provider at an in-network facility (e.g., an anesthesiologist you didn't choose), and out-of-network air ambulance services. In these covered situations, you generally only owe your normal in-network cost-sharing amount — the provider or facility cannot bill you for the difference between their charge and what your plan pays ("balance billing") in these specific circumstances.

If a provider or facility bills you as though the Act didn't apply, or you already paid more than the in-network amount for a covered situation, you can submit a complaint to the No Surprises Help Desk (1-800-985-3059) or through CMS.gov. Separately, providers and health plans that disagree on payment amounts (not you, the patient) use the federal Independent Dispute Resolution (IDR) process — a May 2026 final rule streamlined this process and, for disputes initiated on or after June 11, 2026, reduced the administrative fee to $15 per party.

This protection has real limits: it applies specifically to the emergency, out-of-network-provider-at-in-network-facility, and air-ambulance scenarios described above — it does not make every unexpected medical bill illegal, and it generally doesn't apply if you're uninsured or knowingly chose an out-of-network provider after receiving proper notice and giving written consent.

On January 7, 2025, the CFPB finalized a rule that would have banned credit reporting agencies from including medical debt on consumer credit reports and barred lenders from considering it in lending decisions. That rule was vacated by a federal court in the Eastern District of Texas on July 11, 2025, which found it exceeded the CFPB's statutory authority and conflicted with the Fair Credit Reporting Act. As of mid-2026, that federal rule is not in effect — treat any claim that "medical debt can't appear on your credit report by federal law" as outdated. verify current status, since this is an active and evolving area

What does still apply are the voluntary changes the three major credit bureaus made in 2022–2023: paid medical collections are generally removed from reports, medical collection debt under $500 is generally not reported, and there is typically a one-year grace period before an unpaid medical bill can appear as a collection at all. These are bureau policies, not federal statutory guarantees, and could change. Separately, roughly 15 states have their own laws restricting medical debt credit reporting — but the court's reasoning in vacating the CFPB rule (that FCRA preempts conflicting state law) creates real uncertainty about whether those state laws remain enforceable. verify your specific state's current status

For nonprofit hospitals specifically, federal tax law (IRC Section 501(r)) requires them to have a written financial assistance policy, limit charges for financial-assistance-eligible patients to no more than amounts generally billed to insured patients, and refrain from certain aggressive collection actions before making reasonable efforts to determine financial-assistance eligibility. This is a real, underused right — ask explicitly about financial assistance/charity care before assuming a bill must be paid in full.

If you are uninsured, or you knowingly and voluntarily chose to receive non-emergency care from an out-of-network provider after receiving the required notice and giving written consent to be balance-billed, the Act's core protections generally don't apply to that specific charge.

Ground ambulance transport is largely not covered by the No Surprises Act's balance-billing ban (unlike air ambulances), and remains one of the more common sources of genuine surprise bills. verify current federal/state treatment of ground ambulance billing, since some states have their own separate protections here

A billing error (wrong quantity, duplicate charge, incorrect code) is a different issue from a No Surprises Act violation — it's addressed through the ordinary itemized-bill dispute process with the provider and your insurer, not through the No Surprises complaint channel.

No Surprises Act complaints for clearly covered situations (emergency care, out-of-network specialist at an in-network facility, air ambulance) tend to resolve in the patient's favor once the facts are documented, because the statute's coverage is fairly specific and verifiable.

Plain billing/coding disputes succeed at a high rate when backed by a clear itemized bill and EOB comparison, but can take persistence and multiple rounds of correspondence with a billing department.

Financial assistance/charity care eligibility depends entirely on the specific hospital's policy and your income relative to its thresholds — ask early, since many hospitals limit collection activity while an application is pending.

The medical-debt credit-reporting landscape is currently unsettled following the 2025 court decision — don't assume a specific federal protection is in effect without checking current status.
