The decision also interpreted, in a hotly contested matter of first impression: the statutory requirement for insurers to endorse applications on policies when issued, holding that the insurer had properly endorsed the application. In June 2009, Mr. Pimstone was trial counsel for Blue Shield of California in the high-profile case, Hailey v. California Physicians Service dba Blue Shield of California, which Mr. Pimstone tried to an Orange County jury. The case resulted in a verdict in favor of Blue Shield. The Hailey matter earlier had been the subject of a reported decision interpreting California’s “postclaims underwriting” laws. It was the first rescission case in California to proceed to jury trial. Earlier in 2009, Mr. Pimstone obtained dismissals for his client in the United States District Court in Miami in two significant RICO actions that had been brought by nationwide classes of almost 1 million physicians, and other allied healthcare providers, alleging a conspiracy to underpay providers. After virtually all of the defendants in the case and its predecessor actions had settled for hundreds of millions of dollars in payments to the class, the federal court granted Mr. Pimstone’s client’s motions to dismiss the two cases with prejudice. In 2008, the California Court of Appeal handed down a unanimous published decision in Mr. Pimstone’s Watanabe case that decided an issue of first impression in California: whether health plans can be held vicariously liable for delegated decisions made by contracted medical groups concerning benefit determinations rendered to plan members (insureds). Adopting the legal arguments advanced by Mr. Pimstone on behalf of his client and the industry, the Court of Appeal held that health plans are not vicariously liable for decisions delegated to medical groups. Had the decision gone the other way, California health plans would have faced immense tort liability for numerous decisions rendered on a daily basis by contracted medical groups, which could have altered the structure of managed care in California. Mr. Pimstone argued the appeal, and in the lower court he had successfully tried the Watanabe case to a Los Angeles jury.
