Your No Surprises Act protections

A federal law, in effect since 2022, bans the most common kind of surprise medical bill — the one that shows up weeks after treatment you had no way to price-shop for. Here's what it actually covers.

What counts as a "surprise bill"

The classic case: you go to an in-network hospital for emergency care, or for a planned procedure at an in-network facility, and later get a bill from an out-of-network doctor you never chose or even knew was involved — an anesthesiologist, a radiologist, an assistant surgeon. Before 2022, that doctor could bill you directly for the difference between what your insurer paid and their full charge, a practice known as balance billing. For emergency care and for these ancillary providers at in-network facilities, that's now illegal.¹

What the No Surprises Act actually bans

• Emergency care — you can only be charged your normal in-network cost-sharing, regardless of which hospital or ER doctor treated you, and regardless of whether your plan would otherwise call that provider out-of-network.
• Out-of-network providers at an in-network facility — anesthesiologists, radiologists, pathologists, assistant surgeons, and similar specialists who treat you at an in-network hospital can't balance-bill you, even if they personally don't contract with your plan.
• Air ambulance transport — covered the same way; ground ambulance is not currently covered by the federal law, though some states have their own rules for it.

In all of these cases, your insurer and the provider work out the payment dispute between themselves (through a federal independent dispute resolution process, if they can't agree) — it isn't supposed to become your problem.

What it doesn't cover

You're also entitled to a Good Faith Estimate

If you're uninsured, or you're insured but paying cash instead of using your plan, you can ask any hospital or provider for a Good Faith Estimate of what a scheduled service will cost before you receive it. If your final bill comes in $400 or more over that estimate, you can dispute it through the same federal process.²

If you get a bill that looks like this

1. Check whether the facility itself was in-network for your plan — this protection generally applies when the facility is in-network, even if a specific provider inside it wasn't.
2. Look for whether it was emergency care, or a provider (anesthesiologist, radiologist, etc.) you didn't get to choose.
3. If it looks like a No Surprises Act violation, you can dispute it directly with your insurer, or file a complaint with the federal No Surprises Help Desk at 1-800-985-3059, or through cms.gov/nosurprises.
