The OIG’s Spring 2012 Semiannual Report to Congress summarizes significant OIG enforcement, investigation, and audit activities for the period of October 1, 2011 to March 31, 2012. For this period, the OIG reports expected recoveries of approximately $1.2 billion (representing $483.1 million in audit receivables and $748 million in investigative receivables); exclusions of 1,264 individuals and entities from participation in federal health care programs; 388 criminal actions involving crimes against HHS programs; and 164 civil actions (including false claims and unjust-enrichment lawsuits filed in federal district court, civil monetary penalties settlements, and administrative recoveries related to provider self-disclosure matters). The Inspector General’s message accompanying the report highlights OIG’s expanded use of advanced data analytics as a tool to enhance fraud, waste, and abuse activities. Among other things, such data analytics are being used for risk assessments, targeting oversight efforts, and reducing resources associated with audits, investigations, evaluations, and other program integrity activities.
