IPAs and Per Se Rules: Arizona v. Maricopa County Medical Society

Extract
The recent flurry of antitrust litigation in the health care industry is forcing the courts to reevaluate the legality of existing health care institutions under the Sherman Antitrust Act. One type of institution that poses significant antitrust questions is the independent practice association (IPA), an arrangement which consists of a contractual relationship between subscribers, physicians and an IPA corporate entity. The physicians agree to provide medical services to the IPA's subscribers, who pay a flat rate. In exchange, physicians are reimbursed at rates usually established by a fee schedule.
The Health Maintenance Organization Act of 1973 requires that an IPA, like an HMO, must “assume full financial risk on a prospective basis for the provision of basic health services…” This ensures that the IPA bears the risk that the cost of the services it renders will not exceed the value of the premiums it collects, giving it an incentive to contain costs.
