United's Exit Leaves Monopolies in Many Places

In late April, UnitedHealthcare announced this would be its last year offering health coverage on “all but a handful” of state insurance exchanges. Going forward, the nation’s largest health insurer will only have a presence in New York, Nevada and Virginia's marketplaces.

That will leave Kansas and Oklahoma with just one insurer each, six states with monopolies in more than 50 percent of its counties and four states with only two insurers in most counties.
