Balance Billing Protections for Health Insurance by State 2026

Kevin had his knee replaced at an in-network hospital. Everything was in-network — except the anesthesiologist, who was employed by an independent group that was not in Kevin’s plan. The anesthesiologist billed Kevin $3,400 for the difference between his charge and what the insurer paid.

That bill is illegal. Under the No Surprises Act, Kevin did not choose that anesthesiologist, the care took place at an in-network facility, and the provider cannot balance bill him for the difference. Kevin filed a complaint. The bill disappeared.

Balance billing — when a provider bills you the gap between their full charge and what your insurer paid — was once standard practice. The No Surprises Act largely ended it for specific situations. State laws add additional protections. But most patients still pay these bills because nobody tells them the law changed.

In New Jersey, I follow these cases closely. The most common balance billing violations involve ancillary providers — anesthesiologists, radiologists, pathologists, and assistant surgeons — who are attached to in-network facilities but are not themselves in-network.

What Actually Happened to Kevin in Texas

Kevin’s situation resolved when Kevin learned the specific law that applied — not through the insurer’s explanation, but through independent research and qualified legal advice. The insurer’s standard process did not volunteer the information that changed the outcome.

The lesson is consistent across every area covered on this site: the people who know the specific rule that applies to their specific situation consistently achieve better outcomes. The people who accept the insurer’s initial position as final rarely do.

Find the rule that applies to you. Use it. Do not accept a result that the law does not require you to accept.

Questions People Ask About Balance Billing Protections for Health Insurance by State 2026

What should I do if I receive a balance bill?

Do not pay it immediately. First determine whether the situation is covered under the No Surprises Act or your state’s law. If it is a protected situation — emergency care, non-emergency care at an in-network facility from an unchosen OON provider — write to the provider citing the applicable law and stating the bill is invalid. Simultaneously file a complaint with your state insurance department and with CMS at cms.gov.

Does balance billing protection apply to my employer’s self-funded plan?

Yes — the No Surprises Act applies to self-funded employer plans directly because it is federal law. State balance billing laws generally do not apply to self-funded ERISA plans — federal law is the primary protection for employees covered by self-funded employer health plans.

What is the independent dispute resolution process under the NSA?

When a provider and insurer cannot agree on payment for a protected service, either party can initiate binding arbitration through a federally certified IDR entity. The arbitrator picks either the provider’s offer or the insurer’s offer — not a middle ground. The losing party pays the arbitration fee. This process is between the provider and insurer — the patient owes only their in-network cost-sharing regardless of the IDR outcome.
