MSP Post-Pay Adjustments

If you have received an overpayment because Medicare paid as the primary insurer and another insurance carrier should be the primary payer, follow the instructions on the Part A Overpayment Recovery Unit Voluntary Refund Form.

• A separate refund form is needed for each date of service needing adjustment.
• The reason code area must be completed assigning the appropriate MSP provision to the overpayment (no fault, Worker’s Compensation etc.).
• Include the explanation of benefits from the primary payer with the voluntary refund form.

You have two options:

1. Submit a check with the Part A Overpayment Recovery Unit Voluntary Refund Form. When the claim(s) is adjusted, Medicare will apply the monies to the overpayment.
2. Submit the Part A Overpayment Recovery Unit Voluntary Refund Form without a check and when the claim(s) is adjusted, Medicare will take back the overpayments through the offset process.
