Ohio Rev. Code § 5123.0410
An individual with a developmental disability who moves from one county in this state to another county in this state shall receive home and community-based services in the new county that are comparable in scope to the home and community-based services the individual receives in the prior county at the time the individual moves. If the county board serving the county to which the individual moves determines under section 5126.041 of the Revised Code that the individual is eligible for county board services, the county board shall ensure that the individual receives the comparable services. If the county board determines that the individual is not eligible for county board services, the department of developmental disabilities shall ensure that the individual receives the comparable services.
If the home and community-based services that the individual receives at the time the individual moves include supported living or residential services, the department shall reduce the amount the department allocates to the county board serving the county the individual left for those supported living or residential services by an amount that equals the payment the department authorizes or projects, or both, for those supported living or residential services from the last day the individual resides in the county to the last day of the state fiscal year in which the individual moves. The department shall increase the amount the department allocates to the county board serving the county the individual moves to by the same amount. The department shall make the reduction and increase effective the day the department determines the individual has residence in the new county. The department shall determine the amount that is to be reduced and increased in accordance with the department's rules for authorizing payments for home and community-based services established adopted under section 5123.049 of the Revised Code. The department shall annualize the reduction and increase for the subsequent state fiscal year as necessary.
