What is this letter for?
Medical bills often contain errors such as duplicate charges, services you did not receive or wrong insurance codes. Start by asking for an itemized bill and your insurer’s Explanation of Benefits (EOB). If you were uninsured or self-pay and the bill is at least $400 more than your Good Faith Estimate, the No Surprises Act lets you start a patient-provider dispute within 120 days of the bill. Surprise out-of-network bills for emergency care are also limited by federal law.
Where do you send it?
Send it to the provider’s billing department (and your insurer if the issue is coverage) by mail or patient portal.
Does it need to be notarized?
