No Surprises Act
Can I be balance billed for an emergency room visit out of network?
You went to an emergency room. It turned out to be out of network, or the doctor who treated you was, and now there is a bill for the difference.
Federal law says that bill is capped at what you would have paid in network — and the form you signed at the desk does not change that.
What the law does
Since 2022 the No Surprises Act has limited patient cost sharing for emergency services to the in-network amount, regardless of whether the facility or the clinician participates in your plan.
It covers:
- Emergency services, at any emergency department, in or out of network
- Post-stabilisation care at an out-of-network facility, until you can safely be moved
- Out-of-network clinicians at an in-network facility — the anaesthesiologist, radiologist, pathologist, assistant surgeon or hospitalist you never chose and could not have chosen
- Air ambulance, in or out of network
Your deductible and coinsurance still apply. What cannot be added is the balance between the provider's charge and the plan's allowed amount.
The form you signed does not waive it
Hospitals hand out a consent-to-treat and financial-responsibility form at registration. For emergency care, that form cannot waive this protection. The law is explicit about it, precisely because nobody arriving at an emergency department is in a position to negotiate.
There is a narrow waiver process for some non-emergency out-of-network care, with its own notice requirements and a timing rule. It does not apply to emergencies, and it does not apply to the ancillary clinicians listed above at all.
How to check your own bill
On the EOB, find what your plan calculated as your share for the emergency services. On the bill, find what is being asked. If the bill is higher, the difference is the balance the law caps.
What to ask
Please rebill [service] at the in-network cost-sharing amount of [amount] under the No Surprises Act, and please confirm in writing that the balance of [difference] has been removed.
Say "No Surprises Act" explicitly. Billing offices route these differently once the phrase is used.
If they refuse
You can file a complaint with the federal No Surprises Help Desk, and your state may have its own protections that go further — several do, and some predate the federal law.
Your plan is also worth calling. Providers who balance bill in protected situations create a problem for the insurer too, and the insurer has a compliance channel for it.
One thing to check first
Make sure it really was emergency care as the plan classified it. If the EOB shows the visit adjudicated at in-network cost sharing, the plan has already applied the protection and the provider is billing against their own adjudication — which is a simpler conversation, and the one on the balance billing page.
This is general information, not legal, medical or financial advice, and not a statement about your particular bill. A difference between two documents often has an ordinary explanation, and the billing office is the one who can give it.
