"Testimony
The Centers for Medicare & Medicaid
Services (CMS), the federal agency that oversees Medicaid, estimated that improper payments in the federal-state
Medicaid program were $21.9 billion in fiscal year 2011. The Deficit Reduction
Act of 2005 established the Medicaid
Integrity Program and gave CMS an expanded role in assisting and improving the effectiveness of state activities to ensure proper payments.
Making effective use of this expanded role, however, requires that federal resources are targeted appropriately and do not duplicate state activities.
GAO was asked to testify on Medicaid program integrity. GAO's statement focuses on how CMS's expanded role in ensuring Medicaid program integrity
(1) poses a challenge because of overlapping state and federal activities regarding provider audits and
(2) presents opportunities through oversight to enhance state program integrity efforts.
To do this work, GAO reviewed CMS
reports and documents on Medicaid program integrity as well as its own and others' reports on this topic. In particular, GAO reviewed CMS reports that documented the results of its state oversight and monitoring activities.
GAO also interviewed CMS officials in the agency's Medicaid Integrity Group
(MIG), which was established to implement the Medicaid Integrity
Program. This work was conducted in
November and December 2011. GAO
discussed the facts in this statement with CMS officials.
What GAO Found
The key challenge faced by the Medicaid Integrity Group (MIG) is the need to avoid duplication of federal and state program integrity efforts, particularly in the area of auditing provider claims. In 2011, the MIG reported that it was redesigning its national provider audit program. Previously, its audit contractors were using incomplete claims data to identify overpayments. According to MIG
data, overpayments identified by its audit contractors since fiscal year 2009 were not commensurate with its contractors' costs. The MIG's redesign will result ..."
