Ohio Rev. Code Ann. § 3923.36

No sickness and accident insurance policy shall be construed to exclude illness or injury upon the ground that the insured might have elected to have such illness or injury covered by workers' compensation under division (A)(3) of section 4123.01 of the Revised Code unless the policy clearly excludes work or occupational related illness or injury or the policy, or a separate writing signed by the insured, informs the insured that such coverage is excluded and may be available to the subscriber under workers' compensation as the sole proprietor of a business, a member of a partnership, or an officer of a family farm corporation.
