"When Covered California unveiled its initial slate of 13 carriers last year, their low rates got some attention -- but so did their mix.
While Covered California couldn't boast Aetna or UnitedHealthcare, which instead elected to leave the state's individual market, four major insurers were on board: Anthem Blue Cross, Blue Shield of California, Health Net and Kaiser Permanente.
And the exchange also had drawn in several smaller health plans, like Ventura County Health Plan, which were going to compete for share on the individual market for the first time.
"For me, the story is [these] new participants," Micah Weinberg of the Bay Area Council told California Healthline last summer. "Who exactly they are, and how they are being offered in these marketplaces, is worth watching."
But Ventura County quietly pulled out. A second small carrier, Alameda Alliance, was kicked out.
