To better understand the Medicaid managed care market during a period
of rapid change, we developed a new data set that links Medicaid enrol
lment data with health maintenance organization (HMO) industry data fo
r 1993-1996 to analyze Medicaid enrollment in full-risk health plans.
Nearly half of the Medicaid enrollees in a fully capitated managed car
e for arrangement were in plans in which Medicaid makes up at least 75
percent of the total enrollment, In addition, the number of Medicaid-
only plans has more than doubled since 1993. Commercial-based plans pa
rticipated increasingly in Medicaid managed care during the period, ye
t more than half of the plans entering the Medicaid market were newly
formed.
