Medicaid claims are processed and paid by an automated system that is operated by a contractor and overseen by the Department of Health (Department). In audit 2007-S-115, we examined selected Medicaid claims processed during the six months ended March 31, 2008 to determine whether the claims were processed in accordance with procedures s. We found that the claims were processed in accordance with procedures; however, we identified an error that would have resulted in overpayments of $84,950. When we followed up on this matter, we found that the Department properly addressed the problem we identified and, consequently, significant amounts of improper Medicaid payments have been and will be prevented.
