Ohio Rev. Code § 3901.382
Beginning six months after the date specified in section 262 of the "Health Insurance Portability and Accountability Act of 1996," 110 Stat. 2027, 42 U.S.C.A. 1320d-4, on which a third-party payer is initially required to comply with a standard or implementation specification for the electronic exchange of health information, as adopted or established by the United States secretary of health and human services pursuant to that act, sections 3901.381, 3901.384, 3901.385, 3901.389, 3901.3810, 3901.3811, 3901.3812, and 3901.3813 of the Revised Code apply to a claim submitted to a third-party payer for payment for health care services only if the claim is submitted electronically. A provider and third-party payer may enter into a contractual arrangement under which the third-party payer agrees to process claims that are not submitted electronically because of the financial hardship that electronic submission of claims would create for the provider or any other extenuating circumstance.
