Ohio Rev. Code Ann. § 5124.516

The director of developmental disabilities may adopt rules under section 5124.03 of the Revised Code governing adjustments to the medicaid reimbursement rate for an ICF/IID that undergoes a change of operator. No rate adjustment resulting from a change of operator shall be effective before the effective date of the entering operator's provider agreement. This is the case regardless of whether the provider agreement is entered into under section 5124.511, section 5124.512, or, pursuant to section 5124.515, section 5124.07 of the Revised Code.
