It begins by exploring the rise of the independent physicians association (IPA)/network system that emerged in southern California. The impact of managed care on the revenues of AHCs is also examined. Finally, the chapter discusses the growth of Medicaid managed care and the efforts to enroll low-income persons not previously eligible for public coverage.
