Description	The Medicaid Analytic eXtract (MAX) data is a set of person-level data files on Medicaid eligibility, service utilization, and payments. The MAX data are created to support research and policy analysis. The MAX data are extracted from the Medicaid Statistical Information System (MSIS). The MAX development process combines MSIS initial claims, interim claims, voids, and adjustments for a given service into final action events. Unlike fiscal-based MSIS quarterly files, MAX data are organized into annual calendar year files. There are a number of other "value added" enhancements to the MAX data for users as described below.
