The Department of Health and Human Services Centers for Medicare and Medicaid Services (CMS) suspended Health Net from Medicare enrollment and marketing activities. CMS determined that Health Net was “significantly impaired” with respect to its ability to maintain and administer a prescription drug formulary in its national prescription drug plan (PDP) and local Medicare Advantage prescription drug plan (MA-PD) contracts. CMS imposed the suspension immediately because “it has determined that Health Net’s conduct poses a serious threat to the health and safety of Medicare beneficiaries.” The suspension will remain in effect until “CMS is satisfied that the deficiencies upon which the determination was based have been corrected and are not likely to recur.”
