Ohio Rev. Code § 5124.105: Addendum for disputed costs.

The department of developmental disabilities shall develop an addendum to the cost report form that an ICF/IID provider may use to set forth costs that the provider believes the department may dispute. The department may consider such costs in determining an ICF/IID's medicaid payment rate. If the department does not consider such costs in determining an ICF/IID's medicaid payment rate, the provider may seek reconsideration of the determination in accordance with section 5124.38 of the Revised Code. If the department subsequently includes such costs in an ICF/IID's medicaid payment rate, the department shall pay the provider interest at a reasonable rate established in rules adopted under section 5124.03 of the Revised Code for the period that the rate excluded the costs.
