The Department of Health and Human Services’ Centers for Medicare and Medicaid Services (CMS) imposed a $31,950 civil penalty on Centene Corporation for failing to provide its enrollees with medical services and prescription drug benefits in accordance with CMS requirements. An audit of Centene’s Medicare operations in May 2016 found that Centene failed to comply with Medicare requirements related to Medicare Part D formulary and benefit administration and coverage determinations, appeals, and grievances. CMS found Centene’s failures in these areas were systemic and adversely affected, or had the substantial likelihood of adversely affecting, enrollees. The enrollees experienced, or likely experienced, delayed or denied access to covered benefits, increased out-of-pocket costs, and/or inadequate grievance or appeal rights.
