Almost half of the nation's local commercial insurance markets are majority controlled by one payer, according to the American Medical Association.
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.
These are the metro areas where the largest payer controls less than 30 percent of the market:
