SEATTLE (AP) -- People in Washington who buy their own health insurance through the state's health exchange will have more choices next year and will only see a small rate increase. On Wednesday, the Office of the Insurance Commissioner approved 10 health insurers to sell 90 plans for 2015, according to Stephanie Marquis, spokeswoman for the state insurance commissioner. That's two more insurers than were approved for 2014. Marquis says the average rate change will be 1.9 percent. This new rate is for individuals and families who do not have employer-sponsored health coverage. The exchange board is schedule to certify these plans at a meeting on Thursday.
