What it covers
- Emergency care: you generally cannot be balance billed for emergency services, even out-of-network, and you pay in-network cost-sharing.
- Non-emergency care at in-network facilities: out-of-network providers such as anesthesiologists or radiologists generally cannot balance bill you without your advance written consent, and some cannot ask for it at all.
- Air ambulances: out-of-network air ambulance services are covered.
Ground ambulances are not covered by the federal law, though some states have their own protections.
Good Faith Estimates for uninsured and self-pay patients
If you do not have insurance or choose not to use it, providers must give you a Good Faith Estimate for scheduled care when you book (or on request). If your bill is at least $400 more than the estimate from a provider, you can use the federal patient-provider dispute process. This is useful for planned dental and cosmetic treatment.
If you get a surprise bill
- Do not pay right away. Compare the bill with your Explanation of Benefits.
- Call the provider and your insurer and mention the No Surprises Act.
- Contact the No Surprises Help Desk (1-800-985-3059) or submit a complaint at CMS.gov.
