Ohio Rev. Code § 4123.70
No compensation shall be awarded on account of disability or death from disease experienced by an employee who, at the time of entering into the employment from which the disease is claimed to have resulted, willfully and falsely represented self as not having previously had such disease. Compensation shall not be awarded on account of both injury and disease, except when the disability is caused by a disease and an injury, in which event the administrator of workers' compensation may apportion the payment of compensation provided for in sections 4123.56 to 4123.59 of the Revised Code between the funds as in the administrator's judgment seems just and proper.
If an employee has both occupational disease and an injury, and the administrator can determine which is causing the employee's disability, the administrator shall pay compensation therefor from the proper fund.
Compensation for loss sustained on account of occupational disease by an employee mentioned in division (A)(1) of section 4123.01 of the Revised Code, or the dependents of such employee, shall be paid from the fund provided for in sections 4123.38 to 4123.41 and 4123.48 of the Revised Code.
Compensation for loss sustained on account of a disease by an employee mentioned in division (A)(2) of section 4123.01 of the Revised Code, or the dependents of the employee, shall be paid by the employer of the employee, if the employer is a self-insuring employer.
