Billing Essentials
The No Surprises Act Explained in Plain English
Since 2022, federal law shields patients from most surprise bills. Here is what the No Surprises Act actually covers - and its gaps.
Updated August 18, 2026 · 8 min read
Quick answer
The No Surprises Act protects patients from out-of-network balance billing in emergencies, at in-network facilities, and for air ambulance services. Your cost-sharing must be based on in-network rates. It does not cover ground ambulances or care where you signed a consent form waiving protections.
Why the Law Exists
Before 2022, patients could choose an in-network hospital yet receive separate bills from out-of-network anesthesiologists, radiologists, or ER physicians they never chose. The No Surprises Act closed those loopholes by making providers absorb network differences rather than passing them to patients.
The Three Core Protections
The law covers these situations.
- Emergency services - any facility or provider, regardless of network status, cannot balance bill you.
- In-network facilities - out-of-network providers treating you there (non-emergency) cannot balance bill you.
- Air ambulance - out-of-network air ambulance services cannot balance bill you.
What the Act Does Not Cover
Gaps remain, and knowing them prevents false security.
- Ground ambulance rides - federal protection absent, though many states fill the void.
- Consented out-of-network care - signing a waiver form can forfeit protections.
- Out-of-network facilities chosen deliberately for elective care.
How To Use the Act
If you receive a surprise balance bill matching a protected scenario, dispute it immediately in writing citing the No Surprises Act, notify your insurer, and file a federal complaint if the provider persists. Providers violating the act face federal penalties - documented complaints carry real weight.

Frequently asked questions
Does the No Surprises Act apply to uninsured patients?
Partially. Uninsured patients receive good-faith cost estimates before scheduled care and protections against charges far exceeding estimates.
Can I still sign away my protections?
Yes, for certain non-emergency out-of-network care, providers can seek written consent 72 hours in advance. Read anything placed in front of you at check-in carefully.
