California’s health insurance exchange said more than 30 plans are expected to vie with one another for spots in the state-run marketplace opening next fall. State officials, and those in other states, are eager to flex their purchasing power under the federal healthcare law by selecting only certain individual and small-business health plans for 19 different regions across California. Insurers who aren’t chosen to be among the exchange’s plans can still offer policies outside the exchange. But many people seeking coverage are expected to go through the exchange because they can get government financial and educational assistance according to a report in the Los Angeles Times.
