Utilization of Services in Arizona's Capitated Medicaid Program for Long-Term Care Beneficiaries

The Arizona Long-Term Care System (ALTCS), Arizona's Medicaid program for long-term care (LTC) beneficiaries, capitates contractors to provide a full range of acute and LTC services to financially-eligible beneficiaries determined to be at risk of institutionalization. This article compares the acute care utilization experience of LTC beneficiaries in ALTCS with those in a fee-for-service (FFS) Medicaid program, linking data from both the Medicare and the Medicaid program files. Patterns of use observed in Arizona seem more consistent with a managed care environment than those observed in the FFS comparison. Rates of acute care utilization observed for both the capitated and the FFS program should be of interest to States considering incorporating LTC beneficiaries into their Medicaid managed care program.
