In another merger of health insurance giants, Anthem has agreed to acquire Cigna in a $54 billion deal, leaving only three major providers of health care. Worries remain about the potential effect on consumers and the rising cost of health care.
Some doctors are concerned that the mergers will put too much power in just a handful of insurance companies. The American Medical Association said the mergers will "reduce competition and decrease choice." There are also worries that costs for customers will go up because of less competition. But the health insurers are defending their move. "This will actually improve efficiencies and reduce costs for consumers down the line," said Cigna spokesman Matt Asensio.
