Abstract Beginning in 1999, all states and the District of Columbia were required to report Medicaid enrollee eligibility and claims data in a standard format into the Medicaid Statistical Information System (MSIS). Mathematica Policy Research, on behalf of the Centers for Medicare & Medicaid Services (CMS), has produced research files derived from these data for each state, by calendar year; the research files are known as the Medicaid Analytic eXtract (MAX) files. The MAX files are described in detail in the MAX and Beta-MAX Design Report and Work Plan,1 hereafter referred to as the design report. Much of the text in this chapter and in the introductory sections of the following chapters summarizes information in the design report. Several structural elements and data enhancements make the MAX files better suited for policy research than the MSIS files upon which MAX is built. The calendar year (CY) structure, the collapsing of claim adjustments into final-action claims, and the additional variables gained through linking to external sources (for example, the Medicare Enrollment Database (EDB)) make the MAX files easier for researchers to use than the raw MSIS files. Often, however, MAX files are not available until more than two years after the end of the CY data period. In the past, researchers who have needed more current Medicaid data have had to rely on other less convenient or less complete sources.
