Three of California's largest health insurers have agreed to delay for 60 days planned rate hikes for thousands of customers after state Insurance Commissioner Dave Jones asked for time to review the increases. Aetna, Anthem Blue Cross and PacifiCare agreed to delay the increases for people with individual policies. Unaffected are workers insured through their employers. None of the three insurers had any immediate comment. The announcement Thursday was in contrast to a decision Jan. 15 by Blue Shield of California to defy the commissioner and go ahead with increases that could total up to 59%.
