Ohio Revised Code Title LI. Public Welfare § 5165.105

The department of medicaid shall develop an addendum to the cost report form that a nursing facility provider may use to set forth costs that the provider believes the department may dispute. The department may consider such costs in determining a nursing facility's medicaid payment rate. If the department does not consider such costs in determining a nursing facility's medicaid payment rate, the provider may seek reconsideration of the determination in accordance with section 5165.38 of the Revised Code. If the department subsequently includes such costs in a nursing facility's medicaid payment rate, the department shall pay the provider interest at a reasonable rate established in rules adopted under section 5165.02 of the Revised Code for the period that the rate excluded the costs.
