Case Brief Summary & Legal Analysis
tl;dr: A health insurer sued a large physician clinic for monopolization and collusion. The court rejected the monopolization claim, finding the plaintiff failed to properly define the relevant market, but found sufficient evidence that the clinic illegally agreed with a competitor to divide territories.
Legal Significance: This case is a landmark for its rigorous economic analysis of market definition in the healthcare industry, rejecting Health Maintenance Organizations (HMOs) as a distinct market and narrowly construing the essential facilities doctrine. It distinguishes lawful market power from illegal anticompetitive conduct.

Case Facts & Court Holding
Key Facts & Case Background
Blue Cross & Blue Shield United of Wisconsin and its HMO subsidiary, Compcare, sued the Marshfield Clinic, a large physician-owned clinic, and its HMO subsidiary, Security, under Sections 1 and 2 of the Sherman Act. The Clinic employed 400 physicians and its HMO had non-exclusive contracts with nearly 900 additional independent physicians in north central Wisconsin. In many counties, Security held over 90% of the HMO subscriber base. Compcare alleged that the Clinic monopolized a purported HMO market by controlling an essential number of physicians, making it impossible for Compcare to form a competing HMO network. Blue Cross separately alleged that the Clinic used its monopoly power and colluded with competitors to charge supracompetitive fee-for-service prices. Evidence was presented suggesting the Clinic had an unwritten agreement with a competing HMO, North Central Health Protection Plan (NCHPP), not to establish offices in each other’s primary service areas, effectively dividing the market.
