A prior audit had disclosed, based on a statistical sample, that Ohio had made overpayments to hospitals and long term care facilities totaling $29.3 million (Federal share $17.6 million) during the 4-year period ending December 1992. A financial adjustment was recommended. In response the State contracted with Deloitte and Touche Consulting Group to conduct a review of the overpayment conditions we identified and initiate a retroactive recovery process. Deloitte and Touche's review covered the period January 1, 1989 through May 31, 1996 (a longer period than was covered by our prior audit. The objective of our follow-up audit was to determine the reasonableness of the methodology used by Deloitte and Touche in their review. We found Deloitte and Touche's methodology to identify Medicaid overpayments to be reasonable. We concur with Deloitte and Touche's overpayment findings totaling $34.0 million (Federal share $20.5 million) and recommend the State make a financial adjustment for this amount. State agency officials concurred with our recommendation.
