UnitedHealth to exit individual insurance market in California - latimes.com
"The nation's largest health insurer, UnitedHealth Group Inc., is leaving California's individual health insurance market, the second major company to exit in advance of major changes under the Affordable Care Act."
UHC is only exiting the INDIVIDUAL health insurance market in California, where they were a very small player, covering some 8,000 people, or about 2% of the individual market. They will continue to offer their group plans as well as selling administrative services to larger 'self-insured' businesses.
Anthem Blue Cross, Kaiser Permanente and Blue Shield of California are the largest individual health insurers in California, with a total combined market share of 87%. (2011 Citigroup survey data)
