Californians will get their first look at the health plans to be offered through the state's new insurance exchange and how much that coverage will cost them. Covered California, the state agency running California's health insurance marketplace, is expected to announce the plans today.

Enrollment on the exchange will begin in October, with full coverage starting in January. That's when virtually everyone in the country will be required to have health insurance or pay a penalty. An estimated 5.3 million Californians will be able purchase insurance through Covered California.
