Two of California's largest health plans have agreed to reinstate coverage to nearly 1,200 patients whose policies were dropped after they incurred high medical expenses. Under the deal, patients whose insurance was rescinded by Kaiser Permanente or Health Net since 2004 will be allowed to purchase new insurance regardless of their medical conditions. California is trying to reach similar deals with Anthem Blue Cross, Blue Shield and PacifiCare involving about 4,000 rescissions.
