Can Insurance Deny an Emergency Room Visit?

The Prudent Layperson Standard

Federal law and most state laws require insurers to cover ER visits based on the symptoms that led a "prudent layperson" to seek emergency care — NOT based on the final diagnosis.

What This Means for You

If you experienced symptoms that a reasonable person would consider an emergency — chest pain, difficulty breathing, sudden severe headache, signs of stroke — your ER visit should be covered regardless of whether the final diagnosis was serious.

When Insurers Deny ER Visits

• Retroactive denials: Final diagnosis deemed non-emergency
• Should have used urgent care: Insurer says symptoms weren't severe enough
• Non-emergency use: Visits for chronic conditions or minor issues
• Out-of-network: Balance billing despite No Surprises Act protections

How to Appeal ER Denials

1. Cite prudent layperson standard in your appeal
2. Document presenting symptoms — what you felt, not what the diagnosis was
3. Time and circumstances — was urgent care available? Was it after hours?
4. Triage notes — request ER records showing how you presented
5. State attorney general complaint — if insurer is applying retroactive denials systematically

No Surprises Act Protections

Since 2022, you are protected from surprise bills for out-of-network emergency services. You should only pay what you would at an in-network facility.
