The letter was sent to formally advise the debtor of the amount of money due the Medicare program.
What the letter means
Medicare must be repaid the amount of money specified in the letter.
A check should be sent to the MSPRC for the "total amount due" as quoted in the letter. If you have previously mailed a payment you will receive a letter acknowledging that payment has been applied to the debt and further advise you of any debt owed to Medicare. If a refund is due you will receive a check in a subsequent mailing.
