Ohio Revised Code Title XXXIX. Insurance § 3901.383

(1) Enter into a contractual agreement under which time periods shorter than those set forth in section 3901.381 of the Revised Code are applicable to the third-party payer in paying a claim for any amount due for health care services rendered by the provider;

(2) Enter into a contractual agreement under which the timing of payments by the third-party payer is not directly related to the receipt of a claim form. The contractual arrangement may include periodic interim payment arrangements, capitation payment arrangements, or other periodic payment arrangements acceptable to the provider and the third-party payer. Under a capitation payment arrangement, the third-party payer shall begin paying the capitated amounts to the beneficiary's primary care provider not later than sixty days after the date the beneficiary selects or is assigned to the provider. Under any other contractual periodic payment arrangement, the contractual agreement shall state, with specificity, the timing of payments by the third-party payer.
