How Big is UnitedHealth's Exit From Obamacare?

Analysts say that UnitedHealth’s decision to drop out of the Obamacare insurance market will have little practical impact on the system. The impact of United leaving is small, in part because the insurance provider mainly traffics in employer-based insurance plans, which it does not sell on the insurance exchanges. Sabrina Corlette, a research professor at Georgetown University’s Center on Health Insurance Reforms, says, "Overall, because United was a pretty minor player in this market, it is not a huge impact and there will be some counties where it is reducing the number of carriers to either one or two carriers, but that’s just for 2017."
