Anthem Insurance Co. added nearly 75,000 commercial customers last year, pushing its total up more than 4 percent. Anthem,
a subsidiary of Indianapolis-based WellPoint Inc., now claims a whopping 1.8 million commercial customers in the state. The
trouble is, Anthem's dominance limits price competition, according to benefits brokers, making it hard for local HMOs such
as M-Plan or even some national players to compete.
