Out-of-network or ER claim denied? How to appeal
Out-of-network and emergency denials feel unfair — and the law often agrees. Between the prudent-layperson standard and the No Surprises Act, you may have stronger protections than the denial suggests.
Two situations, two sets of rights
“Out-of-network” denials usually fall into one of two buckets, and the winning argument depends on which one you’re in.
1. Emergency care — the prudent-layperson standard
Emergencies don’t wait for network directories. Under the prudent-layperson standard, coverage is based on your symptoms at the time, not the final diagnosis. If a reasonable person without medical training would have believed they were having an emergency — chest pain, difficulty breathing, severe bleeding — the plan generally must cover the visit at the in-network level, even at an out-of-network ER. If your ER claim was denied or downgraded, say this directly in your appeal and describe the symptoms that sent you in.
2. Out-of-network provider at an in-network facility
You go to an in-network hospital, but an out-of-network anesthesiologist, radiologist, or assistant surgeon treats you — and a surprise bill follows. The No Surprises Act protects you here: for most of these services you can’t be charged more than in-network cost-sharing, and the provider generally can’t balance-bill you the difference.
For most emergency services and many out-of-network providers at in-network facilities, the No Surprises Act limits you to in-network cost-sharing and bans balance billing (CMS).
How to appeal
- State the standard — name the prudent-layperson rule (for ER) or the No Surprises Act (for facility-based out-of-network care).
- Describe the symptoms that made it reasonable to seek emergency care.
- Request in-network processing and in-network cost-sharing.
- Attach the ER records, the bill, and your EOB.

Frequently asked questions
My ER visit was out-of-network and got denied. Can I appeal?
Yes. Emergency care is judged by the prudent-layperson standard — if a reasonable person believed it was an emergency, the plan generally must cover it at the in-network level, even out-of-network. The No Surprises Act also protects most emergency services from balance billing.
What is the prudent-layperson standard?
It means coverage is based on your symptoms, not the final diagnosis. If a reasonable non-medical person would have believed they needed emergency care, the visit should be treated as an emergency — even if it turned out to be minor.
I was treated by an out-of-network doctor at an in-network hospital. Am I protected?
Often yes. The No Surprises Act protects you from surprise out-of-network bills for many services at in-network facilities, limiting you to in-network cost-sharing. See our surprise medical bill guide.
