According to a recent OIG report, “Medicaid Managed Care: Fraud and Abuse Concerns Remain Despite Safeguards,” while all managed care entities (MCE) and states surveyed reported taking steps to address fraud and abuse in Medicaid managed care, program integrity concerns remain. In particular, both MCEs and states are concerned about services billed but not received. The OIG therefore recommends that CMS: (1) require state contracts with MCEs to include a method to verify with beneficiaries whether they received services billed by providers; and (2) update guidance to reflect concerns expressed by MCEs and states. CMS concurred with the recommendations.
