Overpayments

Overpayment Rebuttal Process

You’ll need to know what the rebuttal process is before initiating and know that the outcome of the rebuttal may not change the National Government Services recoupment process.

The overpayment rebuttal process is a protocol used when an account receivable has been set up on a claim(s) and a demand letter has been sent to a provider/supplier.

If providers/suppliers have reason to believe the withhold should not occur, providers/suppliers will have 15 days from the date of the demand letter to notify NGS of rebuttal. The rebuttal may not change the NGS recoupment process.

The rebuttal process is not an appeal of the overpayment determination, it’s a statement of opportunity for providers/suppliers to refute an overpayment and the rebuttal process will not delay the recoupment process.

Under existing regulation 42 CFR section 405.374, providers/suppliers will have 15 days from the date of the demand letter notification to submit a statement of opportunity to rebuttal, including a statement and/or evidence stating why the recoupment should not be initiated. NGS will review the provider/supplier’s documentation and render a decision in 15 days from receipt of provider/suppliers rebuttal request.

Provider/supplier may submit a rebuttal when there is good cause to believe that NGS should not withhold claim payments or offset or recoup on an account receivable.

Common Reasons to Why a Provider/Supplier Would Submit a Rebuttal

  • Repayment for overpayment has already been submitted
  • 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 for Rebuttal Submissions

  • Shall indicate "Rebuttal" in subject line or first sentence of document and on envelope
