Acquired immunodeficiency syndrome in California's Medicaid program, 1981-84.
In this article, Medicaid enrollment, use, and expenditures for persons with acquired immunodeficiency syndrome in California from 1981-84 are examined. The data are from Tape-to-Tape, a person-level Medicaid enrollment and claims data base. It was found that expenditures per month of enrollment decreased as length of enrollment during the year increased. Average annual expenditures increased from 1982 to 1983 and then decreased in 1984. This decrease was most pronounced in hospital services with no indication of a substitution of ambulatory services. This decline is primarily a result of a decrease in hospital reimbursement per day as opposed to changes in use, because discharge rates decreased and length of stay increased.
