The No Surprises Act bans surprise out-of-network bills in emergencies — but has significant gaps. Here is what it covers:

The No Surprises Act is a federal law that took effect January 1, 2022. It protects patients from unexpected medical bills — often called surprise bills — when they receive care from out-of-network providers in specific situations.
Before this law, patients could receive enormous bills from out-of-network providers they never chose — anesthesiologists, radiologists, assistant surgeons, and emergency physicians who happened to be at an in-network facility.
When you receive emergency services at any hospital emergency room — in-network or out-of-network — you cannot be billed more than your in-network cost-sharing amount. The provider cannot balance bill you for the difference between their charge and what the insurer pays.
When you receive non-emergency care at an in-network facility and an out-of-network provider participates in your care without your knowledge or consent — such as an anesthesiologist or assistant surgeon — those providers cannot balance bill you.
Out-of-network air ambulance services from FAA-certified providers are subject to No Surprises Act protections.
Review the circumstances of your care — was it an emergency? Were you at an in-network facility? Did you receive advance notice about out-of-network providers?
They are required to apply No Surprises Act protections to qualifying bills.
If a provider bills you inviolation of the No Surprises Act, file a complaint with the No Surprises HelpDesk at 1-800-985-3059 or online at cms.gov.
For qualifying items and services, the independent dispute resolution process is available to resolve payment disputes between insurers and providers.

Balance billing is when a provider bills you for the difference between their charge and what your insurer paid. The No Surprises Act prohibits balance billing in qualifying situations.
Only in limitednon-emergency circumstances and only after receiving specific written notice and providing written consent. For emergency care, these protections cannot be waived.
No. Ground ambulances are explicitly excluded from No Surprises Act protections. This is one of the most significant remaining gaps in surprise billing protection.
