This report is the third in a series that explores the cross-payer effects of providing Medicaid long-term supports and services (LTSS) on Medicare acute care resource use. The report reflects an exploratory analysis of the relationships between Medicare resource use and Medicaid long-term supports and services to address the question: Does providing Medicaid LTSS influence dually eligible Medicaid recipients’ use of Medicare resources and, if so, how and to what extent? Report results suggest two general aspects of these effects: (1) Medicaid LTSS provided in the community are associated with an increase in the number of Medicare services used with no, or limited, additional Medicare costs overall, and (2) Medicaid institutional supports offset Medicare resource use overall. Analytic methods, including propensity score matching techniques used to conduct this analysis, are also highlighted in the report. Much like the first two reports, this report is intended to provide general background information on the interplay of Medicare and Medicaid resources using data from one state—Maryland—as an example for analysts who are beginning to examine similar issues at the state and federal levels.
