Ohio Rev. Code § 1751.55: Effect of workers compensation coverage.

A health insuring corporation policy, contract, or agreement shall not be construed to exclude illness or injury upon the ground that the subscriber might have elected to have such illness or injury covered by workers' compensation under Chapter 4123. of the Revised Code unless the policy, contract, or agreement clearly excludes work or occupational related illness or injury, or the policy, contract, or agreement, or a separate writing signed by the subscriber, informs the subscriber 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.
