The No Surprises Act is a federal law, effective January 1, 2022, that caps what you pay for most out-of-network care you didn’t choose — emergency treatment, air ambulance transport, and services delivered by out-of-network providers at in-network hospitals and surgery centers.1Centers for Medicare & Medicaid Services. HHS Kicks Off New Year with New Protections from Surprise Medical Bills In those situations, your bill is limited to the in-network deductible, copay, or coinsurance your plan would charge, and the provider is legally prohibited from coming after you for the balance.
Before the law, a trip to an in-network hospital could still generate a five-figure bill from an out-of-network anesthesiologist or radiologist you never chose and often never met. That gap is what the statute closes.
When the Protection Applies
The law targets the situations where surprise bills hit hardest: care you can’t plan for, and specialists you can’t pick.
Emergency Care
All emergency services are covered, whether the hospital or freestanding emergency department is in your network or not. You pay only your in-network cost-sharing, even if the facility and every doctor who treats you are out of network.2U.S. Department of Labor. Avoid Surprise Healthcare Expenses – How the No Surprises Act Can Protect You Emergency mental health visits are included. Your plan cannot require prior authorization or apply stricter limits than it would to an in-network emergency.3GovInfo. 42 USC 300gg-111 – Preventing Surprise Medical Bills
Post-Stabilization Care
Protections don’t end when the crisis ends. Once you’re stabilized, the balance billing ban continues through admission to the hospital, transfer by ambulance to another facility, or placement in observation.4Centers for Medicare & Medicaid Services. No Surprises Act Overview of Key Consumer Protections A provider can ask you to waive post-stabilization protections only if you are well enough to travel to an in-network facility by ordinary transportation, capable of giving informed consent, and given a proper written notice. If no in-network provider is available at the facility, the waiver option is off the table entirely.
Non-Emergency Services at In-Network Facilities
When you schedule a procedure at an in-network hospital or ambulatory surgical center, out-of-network providers who treat you during that visit cannot bill you above your in-network cost-sharing.5Centers for Medicare & Medicaid Services. No Surprises – Understand Your Rights Against Surprise Medical Bills This is the scenario the law was written for: you picked an in-network surgeon and hospital, but the anesthesiologist, pathologist, or radiologist assigned to your case turned out to be out of network.
Air Ambulance
Out-of-network air ambulance providers are also barred from balance billing. Your cost-sharing is calculated as if the transport had been in network.4Centers for Medicare & Medicaid Services. No Surprises Act Overview of Key Consumer Protections
What You Actually Pay
For any service covered by the law, your out-of-pocket cost cannot exceed what you would have paid an in-network provider.5Centers for Medicare & Medicaid Services. No Surprises – Understand Your Rights Against Surprise Medical Bills The provider cannot bill you for the difference between what they charged and what your plan paid — that practice, called balance billing, is what the law prohibits.
Your plan calculates your share against a benchmark called the Qualifying Payment Amount, generally the plan’s median contracted rate for that service in your geographic area.6eCFR. 45 CFR 149.140 – Methodology for Calculating Qualifying Payment Amount So if an out-of-network surgeon bills $5,000 for a procedure and the Qualifying Payment Amount is $1,500, your plan applies your in-network cost-sharing to $1,500. A 20% coinsurance means you owe $300. The surgeon cannot pursue you for the remaining $3,500.
Anything you pay for a protected service counts toward your in-network deductible and out-of-pocket maximum, not a separate out-of-network tally.3GovInfo. 42 USC 300gg-111 – Preventing Surprise Medical Bills
Who Is Covered
The protections reach most people with private coverage: employer group health plans, individual and group plans bought on or off the Marketplace, Federal Employees Health Benefits plans, non-federal governmental plans, church plans, and student health plans offered by colleges and universities.7Centers for Medicare & Medicaid Services. Who Has Protections Under the No Surprises Act
Uninsured and self-pay patients are covered too, but through a different mechanism described below. Health care sharing ministries are not health insurance and are not covered by the law.
What the Law Does Not Cover
Ground ambulance rides are the biggest gap. When you call 911, you have no say over which company responds or whether it’s in your plan’s network, but ground ambulance charges are not protected by the federal law.4Centers for Medicare & Medicaid Services. No Surprises Act Overview of Key Consumer Protections A federal advisory committee issued recommendations in August 2024, but no legislation has followed.8Centers for Medicare & Medicaid Services. Advisory Committee on Ground Ambulance and Patient Billing Some states protect fully insured members from surprise ground ambulance bills; check your state before paying.
The federal law also doesn’t replace state surprise billing laws. Where a state law applies and offers at least equal protection, the state law generally governs; where it doesn’t reach or protects less, the federal law fills in.9Centers for Medicare & Medicaid Services. State Surprise Billing Laws and the No Surprises Act Some states cover services the federal law doesn’t, so it’s worth checking both before assuming you owe a bill that looks wrong.
The Consent Waiver Trap in Planned Care
For planned, non-emergency care, an out-of-network provider can ask you to waive your surprise billing protections. To do so lawfully, they must give you a written notice disclosing their out-of-network status, provide a good-faith cost estimate, tell you that in-network alternatives may exist, and get your signature on a consent form.10Centers for Medicare & Medicaid Services. Frequently Asked Questions for Providers About the No Surprises Rules
Timing is strict. If your appointment is scheduled at least 72 hours out, the notice and consent must happen no later than 72 hours before the procedure. If the appointment is set with less notice, the form must be provided on the day it’s scheduled. Miss any step and the waiver is invalid; your full protections remain.2U.S. Department of Labor. Avoid Surprise Healthcare Expenses – How the No Surprises Act Can Protect You
Some providers can never ask you to waive. Anesthesiologists, pathologists, radiologists, neonatologists, diagnostic testing providers, assistant surgeons, hospitalists, and intensivists are permanently barred from balance billing at an in-network facility. The waiver process does not apply to them, and it does not apply when no in-network provider is available at the facility to do the work.10Centers for Medicare & Medicaid Services. Frequently Asked Questions for Providers About the No Surprises Rules
If You Are Uninsured or Paying Cash
Without insurance, or when you choose not to use it, the law gives you a different tool: a good faith estimate before you receive care. A provider scheduling a service must deliver the estimate within one business day of scheduling when the appointment is at least three business days away, or within three business days when it’s at least ten business days out. You can also request an estimate at any point, and the provider has three business days to produce one.11eCFR. 45 CFR 149.610 – Requirements for Provision of Good Faith Estimates
The estimate has to include expected charges from the primary provider and, where relevant, from other providers and facilities involved. It also has to tell you about your right to dispute the final bill.
If the actual bill exceeds the estimate by $400 or more, you can start the patient-provider dispute resolution process. You have 120 calendar days from the date you receive the bill to file.12Centers for Medicare & Medicaid Services. What You Need to Know About the Administrations Actions to Prevent Surprise Billing A third-party dispute resolution entity reviews the estimate and the bill and sets a fair payment. People enrolled in short-term, limited-duration plans use this same estimate-and-dispute path.7Centers for Medicare & Medicaid Services. Who Has Protections Under the No Surprises Act
What to Do About a Bill That Looks Wrong
If a provider balance bills you for a protected service, fails to apply your in-network cost-sharing, or skips a required notice, you can file a complaint with the federal government. Call the No Surprises Help Desk at 1-800-985-3059 or use the online complaint form at cms.gov.13Centers for Medicare & Medicaid Services. No Surprises Act – How to Get Help and File a Complaint
Before you file, gather your insurance card, the bills in question, your Explanation of Benefits statements, and any consent forms you signed. Keep notes from every phone call with the provider and insurer, and hold onto any collections communications. Someone else can file on your behalf as an authorized representative. Complaints backed by strong documentation move faster, and the Help Desk can investigate violations and coordinate enforcement across federal agencies.
