On May 17, 2013, the HHS Office of Inspector General (OIG) published a final rule amending current regulations prohibiting State Medicaid Fraud Control Units (MFCU) from using federal matching funds to identify fraud through screening and analyzing State Medicaid data (known as data mining). In order to “support and modernize MFCU efforts to effectively pursue Medicaid provider fraud,” the OIG is permitting federal financial participation (FFP) in costs of defined data mining activities under specified circumstances. In addition, the OIG is finalizing requirements that MFCUs annually report costs and results of approved data mining activities to the OIG. The rule is effective on June 17, 2013.
