Question: Who is responsible for identifying and correcting overpayment in any Medicare reimbursement? Is there a lookback period or is any claim ever paid fair game?

Answer: According to the Centers for Medicare & Medicaid Services (CMS), the overpayments may be identified by CMS; a Medicare Administrative Contractor (MAC); or a provider, via self-identification.

CMS leans on providers to keep track of payments. “Through reasonable diligence, a provider can identify any overpayment and calculate the amount,” CMS states in a Medicare Learning Network (MLN) fact sheet.

Section 1128J(d) of the Social Security Act requires providers to report and return any self-identified overpayment to its respective MAC within 60 days of identifying the overpayment, six years since the overpayment (six years constitutes the “lookback period”), or a corresponding cost report due date.

Overpayments of $25 or more will spur a MAC to send a demand letter requiring repayment.

Heads up: One Part B MAC recently reminded providers about the intersection between invoice price and subsequent payments after that fact that may lead to an overpayment — and recoupment.

“Total invoice price is the net amount of provider pays for an item in service, considering ALL discounts, rebates, refunds, or other adjustments,” reminded CGS Medicare in a May 1 release. “In the circumstances that the total invoice amount is paid, and the provider subsequently receives payment from a third party, such as a volume-based discount, rebate, refund, or other adjustments this is considered ‘overpayment.’ The provider is obligated to report and voluntarily refund the overpaid amount.”
