This paper reports on a new survey of state Medicaid managed care payment r
ates. We collected rate data for Medicaid's Aid to Families with Dependent
Children (AFDC)/Temporary Assistance for Needy Families (TANF) and poverty-
related populations and made adjustments to make the data comparable across
states. The results show a slightly more than twofold variation in capitat
ion rates among states, caused primarily by fee-for-service spending levels
and demographics. There is a very low correlation between the variation in
Medicaid capitation rates among states and the variations in Medicare's ad
justed average per capita cost. The data are not sufficient to answer quest
ions about the adequacy of rates but should help to further policy discussi
ons and research.
