Medicare Beneficiaries and HMOs: A Case Study of the Portland Market


This case study of the evolution of Medicare managed care in Portland, Oregon, is part of a series of four case studies being prepared for the Kaiser Family Foundation to learn more about the factors influencing, and consequences of, the growth of Medicare managed care. Portland was one of the first markets to implement a Medicare managed care program, with the Kaiser Foundation Health Plan beginning its Medicare HMO in 1978 and all four of Portland's current Medicare risk contractors serving the Medicare population by the late 1980s.
