For purposes of this division, a "proper invoice" includes the claimant's name, claim number and date of injury, employer's name, the provider's name and address, the provider's assigned payee number, a description of the equipment, materials, goods, supplies, or services provided by the provider to the claimant, the date provided, and the amount of the charge. If more than one item of equipment, materials, goods, supplies, or services is listed by a provider on a single application for payment, each item shall be considered separately in determining if it is a proper invoice.
If prior to a final adjudication the bureau determines that the invoice contains a defect, the bureau shall notify the provider in writing at least fifteen days prior to what would be the required payment date if the invoice did not contain a defect. The notice shall contain a description of the defect and any additional information necessary to correct the defect. If the bureau sends a notification to the provider, the required payment date shall be redetermined in accordance with this division after the bureau receives a proper invoice.
For purposes of this division, "final adjudication" means the later of the date of the decision or other action by the bureau, the industrial commission, or a court allowing payment of the award to the employee from which there is no further right to reconsideration or appeal that would require the bureau to withhold compensation and benefits, or the date on which the rights to reconsideration or appeal have expired without an application therefor having been filed or, if later, the date on which an application for reconsideration or appeal is withdrawn. If after final adjudication, the administrator of the bureau of workers' compensation or the industrial commission makes a modification with respect to former findings or orders, pursuant to Chapter 4123., 4127., or 4131. of the Revised Code or pursuant to court order, the adjudication process shall no longer be considered final for purposes of determining the required payment date for invoices for equipment, materials, goods, supplies, or services provided after the date of the modification when the propriety of the invoices is affected by the modification.
If a state agency pays interest charges under this section, but determines that all or part of the interest charges should have been paid by another state agency, the state agency that paid the interest charges may request the attorney general to determine the amount of the interest charges that each state agency should have paid under this section. If the attorney general determines that the state agency that paid the interest charges should have paid none or only a part of the interest charges, the attorney general shall notify the state agency that paid the interest charges, any other state agency that should have paid all or part of the interest charges, and the director of budget and management of the attorney general's decision, stating the amount of interest charges that each state agency should have paid. The director shall transfer from the appropriate funds of any other state agency that should have paid all or part of the interest charges to the appropriate funds of the state agency that paid the interest charges an amount necessary to implement the attorney general's decision.
