In certain situations, your health care provider may be unable or unwilling to submit a bill (file a claim) to Medicare. Listed below are a few reasons why your provider may refuse to file a Medicare claim, along with information about what to do in each situation.

  • Your provider believes Medicare will deny coverage.
    • Your provider must ask you to sign an Advance Beneficiary Notice (ABN).
    • Before signing an ABN, ask additional questions to find out whether your provider considers the service to be medically necessary, and whether they will help you appeal.
    • Ask your provider to still file a claim with Medicare, even if they believe coverage will be denied. You may be able to appeal if Medicare denies coverage.
  • Your provider may ask that you pay in full for services.
    • If you are seeing a participating provider, ask your provider to submit the claim to Medicare. Medicare should let you know what you owe after it has processed the claim . You may also find it useful to contact your state’s medical licensing board to report the issue.
    • Non-participating providers are allowed to request payment up front at the time of service. Ask your provider to file a claim with Medicare on your behalf, so you can receive Medicare reimbursement (80% of the Medicare-approved amount).
  • Your provider has opted out of Medicare.
    • Opt-out providers have signed an agreement to be excluded from the Medicare program. They do not bill Medicare for services you receive.
    • You should not submit a reimbursement request form to Medicare for costs associated with services you received from an opt-out provider. You are responsible for the entire cost of care when seeing an opt-out provider.
  • Your provider refuses to bill Medicare and does not specify why.

If a provider continues to refuse to bill Medicare, you may want to try filing the claim yourself. Submit a Patient’s Request for Medicare Payment form (also called the CMS-1490S form) to the Medicare Administrative Contractor (MAC) in your area. You must send bills or receipts for the service along with the form. After processing your request, Medicare should either send reimbursement or a coverage denial that you can appeal. To find the MAC in your area, call 1-800-MEDICARE.
