Five Southern California hospitals filed suit Monday alleging improper conduct by the state's largest health plan operator. The suit, filed by Long Beach Memorial and four sister hospitals in LA and Orange Counties, accuses Blue Cross of California of approving expensive treatments for its members and later refusing to pay. The latest allegations follow on the heels of 23 lawsuits filed on behalf of individual policyholders, who claim Blue Cross and Blue Shield dumped them for trivial mistakes on their applications, after receiving bills for their medical care. The company has denied any wrongdoing in the individual's suits. Host Patt Morrison is joined by Lisa Girion, staff Writer for the Los Angeles Times, who has been covering this story.
