Emergency care is the heart of the No Surprises Act. For a patient with private group or individual coverage, every out-of-network emergency claim is protected, whether or not the hospital is in network: the patient pays in-network cost-sharing, you can’t balance bill, and any dispute over the payment goes to open negotiation and independent dispute resolution (IDR) — or a state process where one applies.
For emergency groups, that makes out-of-network payment a plan-versus-provider negotiation by default, and a high-volume one.
What the law protects
- Emergency services at hospital emergency departments and independent freestanding emergency departments, up to the point the patient is stabilized.
- Post-stabilization services, unless the strict notice-and-consent conditions are met. Those include the treating physician determining the patient can travel to an available in-network provider or facility within a reasonable travel distance, using nonmedical or nonemergency medical transportation, and the patient being in a condition to give informed consent.
- No prior authorization may be required for emergency services, and the plan can’t impose stricter conditions or higher cost-sharing because you’re out of network.
For care before stabilization, there’s no consent route: the protections can’t be waived.
Why emergency claims get underpaid
| Cause | What it looks like | Where to fix it |
|---|---|---|
| Payment anchored to the QPA | Allowed amount at or near the plan’s median in-network rate | Open negotiation, then IDR |
| Level-of-service downcoding | A high-acuity visit paid as a lower E/M level | Plan appeal or corrected claim |
| Reclassified as non-emergency | Denial or reduction based on the final diagnosis | Appeal under the prudent layperson standard |
| Wrong plan type | A self-funded plan treated as state-regulated, or the reverse | Confirm which process applies |
The first is a rate dispute and belongs in IDR. The others are coding or coverage disputes, and they go through the plan’s appeals process first. See how to handle out-of-network underpayments.
The prudent layperson standard
Plans must decide whether care was an emergency based on whether a reasonable person with average health knowledge would have thought it was one, not solely on the final diagnosis code. A patient with chest pain who turns out to have reflux still presented with an emergency. Denials or reductions that rest only on the discharge diagnosis are worth appealing.
Building the IDR offer
The IDR entity weighs the QPA alongside other factors, and emergency medicine has strong ones:
- Patient acuity — the severity of the presentation, critical care time, resuscitation.
- Complexity — the workup and decision-making the case required.
- Training and experience — board certification and the group’s staffing model.
- Contracting history — evidence of good-faith efforts to go in network with the payer.
Offers anchored to billed charges or Medicare rates carry no weight: the IDR entity may not consider either. More on the QPA and what the IDR entity can weigh.
Volume is the strategy
Emergency groups rarely face one big underpayment. They face thousands of small ones from the same payers. That changes the approach:
- Batch qualifying claims from the same payer for the same service to make disputing them economical.
- Track results by payer and visit level. A payer that consistently pays a fraction of what IDR awards is a pattern worth pressing, and evidence for a contract negotiation.
- Watch the deadlines across volume. At emergency-department scale, a missed 30-business-day window costs real money every month. The federal IDR timeline sets out every clock.
State law and self-funded plans
Many states had emergency surprise-billing laws before the No Surprises Act, and where a state law governs a claim, it generally replaces the federal process. But state laws generally can’t reach self-funded employer plans governed by ERISA, so the same visit can go to a state process for one patient and federal IDR for another. See federal vs. state IDR and our state guides for New York, New Jersey, Texas, Georgia and California.
