The No Surprises Act, Explained: Your Rights When the Bill Arrives

Before 2022, a fully insured patient could go to an in-network hospital for surgery and still receive a $30,000 bill from the out-of-network anesthesiologist who happened to be assigned to the case. The patient had no way to know. They had no way to choose otherwise. They just got the bill — and it counted as legal under the doctrine of "balance billing."

The No Surprises Act ended that for most situations. It is the most consequential consumer-protection law in healthcare in a generation, and most patients have no idea it exists or what it does for them.

What the law banned. Surprise out-of-network bills are now illegal in three big situations:

— Emergency care. If you go to any emergency room — in-network or not — you cannot be balance-billed beyond your in-network cost-sharing. This includes air ambulance rides. — Out-of-network providers at in-network facilities. The classic anesthesiologist-at-an-in-network-hospital case. You're protected as long as the underlying facility is in-network. — Post-stabilization care. Once an emergency is stabilized, providers must give you written notice and consent before delivering further out-of-network services.

In all of these cases, you owe only what your in-network cost-sharing would be — your normal copay, coinsurance, or deductible. The provider has to settle the rest with your insurer through an independent dispute resolution process. You're not part of that fight.

What "Good Faith Estimates" mean. If you're uninsured or self-paying, providers are required to give you a Good Faith Estimate of expected charges in writing before any scheduled care. This estimate must include the primary service and any reasonably-expected items and services that go with it.

The estimate is enforceable. If your final bill comes in more than $400 above the Good Faith Estimate for any single provider, you can challenge it through the federal Patient-Provider Dispute Resolution process. It costs $25, and the dispute resolver decides what you owe based on market rates. Save every Good Faith Estimate you receive. They are the receipt that gives the law teeth.

What's still allowed. The No Surprises Act has limits. Balance billing is still legal at out-of-network facilities for non-emergency care if you sign a written waiver acknowledging it. Ground ambulance rides are not yet covered (they were left out of the original law and Congress is still working on closing that gap). And the law doesn't change what your insurer covers — only what you can be charged on top of what insurance pays.

What to do if you get a surprise bill anyway. Don't pay. Call the provider's billing office and tell them the bill appears to violate the No Surprises Act. Ask for it to be reviewed. If they refuse, file a complaint with CMS at no-surprises.cms.gov or call 1-800-985-3059. Penalties for providers and facilities can run up to $10,000 per violation. They take this seriously — the patient who reports them does the federal government a favor.

A working knowledge of the No Surprises Act is worth thousands of dollars. It's also the kind of thing nobody tells you about until you need it.
