Final answer:
When a Medicare RAC demands repayment, you have the option to either repay within 10 days or explain why you cannot pay at the moment.
Step-by-step explanation:
When a Medicare Recovery Audit Contractor (RAC) sends you a letter demanding repayment, you have two options. First, you can repay the RAC within 10 days. Alternatively, you can send the RAC a letter explaining why you cannot pay right now. It is important to respond to the RAC's letter and address the matter promptly, as failing to do so may result in CMS taking the money directly from you.
