The AMA’s annual “Competition in Health Insurance” report, published in December, found that 73% of metropolitan areas have “highly concentrated” commercial health insurance markets. In 90% of metropolitan areas, one payer has at least a 30% market share in combined HMO, PPO, point-of-sale and exchange markets. In 48% of markets, one insurer had a share of
50% or more.
