Ohio Revised Code Title XXXIX. Insurance § 3923.332

(A) No medicare supplement policy or certificate in force in this state shall contain benefits that duplicate benefits provided by medicare.

(B) Notwithstanding section 3923.04 of the Revised Code or any other provision of law of this state, a medicare supplement policy or certificate shall not exclude or limit benefits for losses incurred more than six months from the effective date of coverage because it involved a preexisting condition.
