A recent GAO report, “Medicaid Integrity Program: CMS Should Take Steps to Eliminate Duplication and Improve Efficiency,” points to a number of shortcomings in CMS Medicaid program integrity efforts. Among other things, the GAO found that Medicaid Integrity Group's (MIG) oversight and support activities had mixed results in achieving the goal of enhancing program integrity efforts. Moreover, the MIG’s hiring of separate review and audit contractors for its National Medicaid Audit Program was inefficient and duplicative. The GAO recommends that CMS: eliminate duplication by merging contractor functions, use comprehensive reviews to better target audits; work with states to ensure reliable reporting of their program integrity recoveries; discontinue state program integrity assessments that overlap other, more current data sources; and reevaluate its return on investment methodology.
