The Law That Stopped Hospitals From Sending You Surprise Bills Just Lost a Key Piece in Court

By Mike Harper · August 12, 2026

The law that was supposed to end surprise medical bills just had its payment formula thrown out by a federal appeals court. Your protection as a patient hasn’t changed yet — but the system that keeps providers and insurers from sending you the bill is now in legal limbo.

The full 17-judge 5th U.S. Circuit Court of Appeals in New Orleans ruled Tuesday that federal agencies improperly calculated the benchmark rate used to settle disputes between doctors and insurers under the No Surprises Act — the 2020 law that bars hospitals and emergency providers from billing patients directly for out-of-network care.

The ruling sided with doctors and air ambulance companies who argued the formula was rigged in insurers’ favor. The court said the government allowed insurers to include so-called “ghost rates” — contracted amounts for services providers never actually perform — when calculating the median payment rate, while simultaneously excluding bonus and incentive payments that are part of real-world compensation. The result, providers argued, was a benchmark that systematically undervalued their services.

The stakes behind the formula are enormous. Arbitration awards to out-of-network providers under the system reached $14.9 billion in 2025, up from $4.1 billion in 2024. The formula that was just struck down determined the starting point for every one of those disputes.

Here’s why this matters to you directly. The No Surprises Act works by keeping patients out of the fight. When you go to an emergency room and an out-of-network doctor treats you, the law says you pay only your in-network cost-sharing amount. The doctor and the insurer then argue over the rest between themselves, using the payment formula as a reference point. That formula determines both what the insurer offers and what you owe in copays or coinsurance.

If the formula goes away without a replacement, the reference point for setting your cost-sharing disappears too. In theory, patients remain protected from balance billing — the court didn’t strike down that part of the law. But the mechanism that determines what your share actually costs is now undefined.

The court anticipated this problem. In its unsigned opinion, the majority said agencies could temporarily let insurers keep using the existing formula through enforcement discretion while developing a replacement. The government has done this before — federal agencies have been operating under various forms of enforcement flexibility since the first legal challenges to the formula began in 2023.

The Texas Medical Association, which brought the lawsuit, has now won five separate legal challenges to how the No Surprises Act is implemented. The pattern is consistent: providers say the rules favor insurers, courts agree, and the government goes back to rewrite the regulations while the old system limps forward.

For patients, nothing changes tomorrow. You still can’t be balance-billed for emergency care. You still pay your in-network rate when an out-of-network provider treats you at an in-network facility. But the formula that translates those protections into actual dollar amounts is now legally invalid — and whatever replaces it will determine whether your share goes up, goes down, or stays where it is.

The system Congress built to end surprise medical bills has been in court for four years, rewritten three times, and now partially struck down again. The protection still exists on paper. Whether it works in practice depends on what happens next.
