The overpayments function in the Noridian Medicare Portal (NMP) allows suppliers to view a summary of claims that may have caused an overpayment. The Overpayment Results inquiry in the NMP will provide users the overpayment information such as what claim(s) caused the overpayment and the steps being taken to satisfy the overpayment. Through this function suppliers can identify any offsets and the beneficiary’s name tied to the offset. To perform an inquiry:

• Select Financials tab
• Select Overpayment Results tab
  • Enter Provider/Supplier details for overpayment
  • Enter Overpayment Letter Number and/or Claim Number (CCN)
  • View most recent 100 or download a csv. file
• Results provides summary
  • Click on plus symbol (+) next to CCN to obtain Beneficiary Name, Claim Number, Date of Service and Overpayment Amount
