How to Appeal a Surprise Medical Bill

The No Surprises Act protects you from unexpected out-of-network bills for emergency care and certain non-emergency services. Learn how to use these protections.

No Surprises Act Overview

Since January 2022, the No Surprises Act protects you from surprise bills in these situations:

  1. Emergency services — regardless of whether the facility is in-network
  2. Non-emergency services at in-network facilities — from out-of-network providers you didn't choose
  3. Air ambulance services from out-of-network providers

What the Law Requires

  • You pay only in-network cost-sharing amounts
  • Out-of-network providers and insurers must resolve payment disputes through arbitration
  • You must receive a good faith estimate before scheduled services
  • Facilities must provide notice of any out-of-network providers

How to Dispute a Surprise Bill

  1. Check if the No Surprises Act applies to your situation
  2. Contact your insurer — tell them the bill violates the No Surprises Act
  3. Contact the provider — inform them you are protected from balance billing
  4. File a complaint with CMS at 1-800-985-3059 if the protection isn't honored
  5. Use the patient-provider dispute resolution process for uninsured or self-pay situations

Good Faith Estimate Rights

If you're uninsured or paying out-of-pocket, providers must give you a good faith estimate of costs. If the actual bill exceeds the estimate by $400 or more, you can dispute it.

Frequently Asked Questions

Does the No Surprises Act apply to all insurance plans?

The No Surprises Act applies to most private health plans including employer plans and marketplace plans. It does not apply to original Medicare (which has its own protections) or plans that aren't regulated under federal law.

What if I signed a consent form waiving my rights?

For emergency services, you cannot be asked to waive your rights. For non-emergency services, providers can ask you to consent to out-of-network care, but strict notice and consent requirements must be met.
