Ohio Rev. Code § 742.22
A member of the fund who is receiving disability benefits from the Ohio police and fire pension fund and is restored to active duty as a member of a police or fire department shall, in computing years of service under section 742.37 or 742.39 of the Revised Code, be given service credit for the time the member was receiving such disability benefits.
On restoration to active duty as a member of a police or fire department, the member shall make contributions to the fund in accordance with section 742.31 of the Revised Code, and the member's disability benefits shall be terminated on the first day following restoration to active duty. In determining the amount of the member's account after the termination of disability benefits, the total sum of the disability benefits paid shall be deducted from any refund payable to the member under division (G) of section 742.37 of the Revised Code.
The employer shall notify the board of trustees of the Ohio police and fire pension fund of the member's return to active duty before the end of the month then current, designating the date of the resumption of active duty. If the member is paid any amount of disability benefits to which the member is not entitled under this section, such amount shall be repaid to the fund by the member or shall be recovered by a withholding from subsequent retirement allowances or other amounts payable under this chapter.
