Health benefits provider Anthem (formerly WellPoint), through its subsidiaries, provides health coverage to more than 39 million members. One of the US' largest health insurers, Anthem is a Blue Cross and Blue Shield Association licensee in more than a dozen states (where it operates as Anthem, Empire, and BCBS) and provides plans under the Unicare, Amerigroup, and CareMore names in other states. Plans include PPO, HMO, indemnity, and hybrid plans offered to employers, individuals, and Medicare and Medicaid recipients. Anthem also provides administrative services to self-insured groups, as well as specialty insurance. In 2017 a federal judge ruled to block the merger between Anthem and rival Cigna.
