The first obstacle faced by Martin Hickey: the broken computers. He had just relocated from upstate New York to New Mexico to launch a new health insurance company. Along with the challenges of building a network of doctors and recruiting patients, the computers in his new office didn't work. Printer paper was nowhere to be found.Hickey, in a way, is a bit of an anomaly: He's starting a new health plan in a market that has been in a period of contraction. As some small plans fold and others merge, the American Medical Association estimates that 70 percent of the insurance market is "highly concentrated," with few options for consumers to choose from.
