Call 1-800-MEDICARE (1-800-633-4227) if you think you may be owed a refund on a Medicare premium. Some Medicare Advantage (Medicare Part C) plans reimburse members for the Medicare Part B premium as one of the benefits of the plan. These plans are sometimes called Medicare buy back plans.

Voluntary refunds can be submitted by using the eCheck option and selecting the option within the eCheck form indicating the payment is not associated with a demand letter. A copy of the voluntary refund form and any other relevant documents must be uploaded and attached to the eCheck to assist in processing.

You may be reimbursed the full premium amount, or it may only be a partial amount. In most cases, you must complete a Part B reimbursement program application and include a copy of your Medicare card or Part B premium information.

The State Medicaid Agency (SMA) initiates provider recoupment upon the discovery of an overpayment, for example, as the result of a provider utilization review audit, receipt of a claims adjustment request, or for situations where provider owes monies to the SMA due to fraud or abuse.

A voluntary refund should be made to Medicare any time an overpayment has been identified by a provider. Overpayments are Medicare funds that a provider, physician, supplier or beneficiary has received in excess of amounts due and payable by Medicare.

An overpayment is when a beneficiary receives more money for a month than the amount they should have been paid. The amount of the overpayment is the difference between the amount the beneficiary received and the amount due.

When Medicare identifies an overpayment, the amount becomes a debt you owe the Federal government. Federal law requires the Centers for Medicare & Medicaid Services (CMS) to recover all identified overpayments.
