Patterns of Medicaid utilization and expenditures in selected states: 1980-84.

Data from the Medicaid Tape-to-Tape project are presented for 5 years, 1980-84, and for five States--California, Georgia, Michigan, New York, and Tennessee. These States represent a range of generous to restrictive Medicaid program characteristics. Utilization and expenditure measures are presented for most Medicaid services: hospital services, long-term care, physician services, and prescription drugs. Data are further disaggregated by major eligibility group: children and adults covered by Aid to Families with Dependent Children; aged and disabled covered by Supplemental Security Income. Previous findings of a high degree of Medicaid diversity among States are confirmed here.
