Ohio Revised Code Title XLI. Labor and Industry § 4123.46

(B) All self-insuring employers, in compliance with this chapter, shall pay the compensation to injured employees, or to the dependents of employees who have been killed in the course of their employment, unless the injury or death of the employee was purposely self-inflicted, and shall furnish the medical, surgical, nurse, and hospital care and attention or funeral expenses as would have been paid and furnished by virtue of this chapter under a similar state of facts by the bureau out of the state insurance fund if the employer had paid the premium into the fund.

If any rule or regulation of a self-insuring employer provides for or authorizes the payment of greater compensation or more complete or extended medical care, nursing, surgical, and hospital attention, or funeral expenses to the injured employees, or to the dependents of the employees as may be killed, the employer shall pay to the employees, or to the dependents of employees killed, the amount of compensation and furnish the medical care, nursing, surgical, and hospital attention or funeral expenses provided by the self-insuring employer's rules and regulations.

(C) Payment to injured employees, or to their dependents in case death has ensued, is in lieu of any and all rights of action against the employer of the injured or killed employees.
