Claim Overpayments

Claim overpayments can occur for a number of reasons, including, but not limited to: a change to member eligibility; a billing error; or invalid fee schedule information. When claim overpayments occur, regardless of the reason, we will take action to recover the overpayment amounts in accordance with the Health Claim Authorization, Processing and Payment Act (HCAPPA), P.L.2005 c.352.

  • Returning Horizon Identified Overpayments

    When Horizon identifies that a claim overpayment has been made, we will initiate a claim adjustment and generate a refund request letter to the payee. This letter will provide the details of the adjusted claim, indicate the overpayment amount to be recovered and provide instructions for the return of the overpayment amount.

    If you receive a refund request letter, it will include instructions to mail the overpayment, along with a copy the letter, to:
