(A) A payment made by a third-party payer to a provider in accordance with sections 3901.381 to 3901.386 of the Revised Code shall be considered final one year after payment is made. After that date, the amount of the payment is not subject to adjustment, except in the case of fraud by the provider.
(B) A third-party payer may recover the amount of any part of a payment that the third-party payer determines to be an overpayment if the recovery process is initiated not later than one year after the payment was made to the provider. The third-party payer shall inform the provider of its determination of overpayment by providing notice in accordance with division (C) of this section. The third-party payer shall give the provider an opportunity to appeal the determination and shall not charge the provider a fee for an appeal. If the provider fails to respond to the notice within sixty days after the notice is made, or appeals the determination but the appeal is denied, the third-party payer may initiate recovery of the overpayment.
When a provider has failed to make a timely response to the notice of the third-party payer's determination of overpayment, the third-party payer may recover the overpayment by deducting the amount of the overpayment from other payments the third-party payer owes the provider or by taking action pursuant to any other remedy available under the Revised Code. When a provider appeals the determination but the appeal is denied, the third-party payer shall permit a provider to repay the amount by making one or more direct payments to the third-party payer or by having the amount deducted from other payments the third-party payer owes the provider.
(C)(1) The notice of overpayment a third-party payer is required to give a provider under division (B) of this section shall be made in accordance with division (C)(2) of this section and shall specify all of the following:
(a) The full name of the beneficiary who received the health care services for which overpayment was made;
(b) The date or dates the services were provided;
(c) The amount of the overpayment;
(d) The claim number or other pertinent numbers;
(e) A detailed explanation of basis for the third-party payer's determination of overpayment;
(f) The method in which payment was made, including, for tracking purposes, the date of payment and, if applicable, the check number;
(g) That the provider may appeal the third-party payer's determination of overpayment, if the provider responds to the notice within sixty days;
(h) The method by which recovery of the overpayment would be made, if recovery proceeds under division (B) of this section.
(2) A third-party payer shall give a provider a notice of overpayment in writing. If the third-party payer and provider use an agreed-upon established electronic notification system, the third-party payer shall notify the provider electronically through that system.
(D) Any provision of a contractual arrangement entered into between a third-party payer and a provider or beneficiary that is contrary to divisions (A) to (C) of this section is unenforceable.
