The Medicare-Medicaid Linked Enrollee Analytic Data Source (MMLEADS) has been developed to allow for the examination of all Medicare and Medicaid enrollment and claims data for those who were dually enrolled in both programs. The current files are intended for both CMS and external researcher use. They are primarily designed to address questions regarding eligibility, enrollment, cost, use, and select physical and mental health conditions. This comprehensive suite of annual, calendar year data files contains Medicare Beneficiary Files, Medicaid Beneficiary Files, Medicare Service Files, Medicaid Service Files, and Conditions Files.
