Many situations may cause a supplier to owe Medicare money on previously paid claims.
- Noridian initiated claim edit correction
- Contractor claim reviews (Noridian, Recover Auditor, Comprehensive Error Rate Testing (CERT), Office of Inspector General (OIG), etc.)
- Claim paid when should have denied had all beneficiary services been submitted in sequential order (e.g. Skilled Nursing Facility (SNF) or hospital admissions)
- Changes to beneficiary's eligibility as maintained by Social Security Administration (e.g. date of death, cancelled policy, election of a Managed Care Plan)

CMS requires the DME MAC to request refunds on overpayments of $25 or more. If a supplier owes several small overpayments, each of which is less than $25, the total amount owed will be aggregated at the end of the month. DME MACs will accept refunds of less than $25. A supplier must submit specific documentation to support the extended repayment plan request.
A supplier may submit a rebuttal when there is good cause to believe the DME MAC should not withhold claim payments to offset a recouped account receivable.
Common Reasons to Submit a Rebuttal
- Check has been submitted for payment
- Overpayment was created in error
- Overpayment was created for a full, instead of a partial claim adjustment, and a clarification is included with rebuttal statement
Request Rebuttal in Writing (E.g. Business Letter or Memo)
To ensure correct processing:
- Clearly indicate "Rebuttal" in subject line or first sentence of document and on envelope
- Clearly state reason for rebuttal and include supporting documentation, e.g., cashed checks
- Include a copy of original overpayment letter with rebuttal statement. If original overpayment letter is not available, include below in rebuttal
- Supplier's name
- National Provider Identifier (NPI) or Provider Transaction Access Number (PTAN)
- Document Control Nnumber (DCN)
- Beneficiary Medicare number
- Date of service (DOS)
Mail overpayment rebuttals to Noridian.
Rebuttal will be reviewed and a written response will be sent to the supplier.
If a supplier has a rebuttal question on a Recovery Auditor Overpayment, view the Recovery Auditor Determinations - Agree or Disagree webpage.
A voluntary refund is a situation that causes a supplier to owe money to Medicare on a previously paid claim(s). Although Medicare may have not notified the supplier of this overpayment, a voluntary refund must be submitted.
To ensure proper recording and timely processing, submit a voluntary refund on the applicable completed "MSP Overpayment Refund Form" or "Non-MSP Overpayment Refund Form" to Noridian. Instructional details and mailing address are included within the appropriate form.
