This article reports the experience of a 15-person primary care group with two health maintenance organization/independent practice association (HMO/IPA) contracts. In 1986 the group received over $1.5 million in capitated payments from the plan to cover medical care of approximately 4,000 patients. The expenses exceeded the income for one plan. Analysis of primary care, specialty care, and ancillary services provides insight into factors that must be considered in evaluating HMO/IPA contracts.
