Blue Cross & Blue Shield United of Wisconsin v. Marshfield Clinic
United States Court of Appeals for the Seventh Circuit
65 F.3d 1406 (1995)
Insurance company Blue Cross & Blue Shield United of Wisconsin (plaintiff) and its subsidiary health-maintenance organization (HMO), Compcare (plaintiff) filed a claim against Marshfield Clinic (defendant), a physician-owned clinic, and its subsidiary HMO, Security Health Plan of Wisconsin (Security) (defendant). The claim alleged anticompetitive behavior in violation of the Sherman Act. Specifically, Compcare argued that Security had contracted with such a large number of physicians in the relevant region that Compcare was unable to recruit physicians and offer HMO buyers prices that were competitive with Security and that therefore Security had a market monopoly.
