Medicaid Analytic eXtract (MAX) Chartbooks


The Medicaid Analytic eXtract (MAX) Chartbooks are research tools and reference guides on Medicaid enrollees and their Medicaid experience in 2002, 2004 and 2008. Developed for state Medicaid directors, policymakers, researchers, and others interested in the Medicaid program, the chartbooks consists of illustrative graphs, descriptive text, and an extensive data appendix with summary national- and state-level information on enrollee demographic and eligibility characteristics, Medicaid service use, and Medicaid expenditures in 2002, 2004 and 2008. The chartbooks summarize the Medicaid program and the MAX data system. They also present figures and tables that reflect the Medicaid population in 2002, 2004 and 2008. For each of the three chartbooks, Chapter 2 profiles Medicaid enrollees and their Medicaid experience nationally, Chapter 3 presents state-level detail, and Chapters 4 through 6 provide supplementary information on special topic areas, including managed care, dual Medicare/Medicaid enrollees, and service use and expenditures by detailed type of service. An appendix contains source data tables for Chapters 3 through 6. A new chapter has been added to the latest chartbook that presents data for 2008, Chapter 7 on Medicaid waiver enrollment and utilization. The MAX Chartbooks (in PDF format) and their associated appendix tables (as zipped Excel files) can be downloaded below.

There is also a chartbook for MAX 2008 with a focus on patient “encounter” records for services delivered through prepaid managed care plans.  This chartbook describes the service utilization of Medicaid enrollees in managed care plans in MAX 2008 data. The chartbook extends the analysis of the previous MAX chartbooks, which focused on the service utilization of Medicaid enrollees covered on a fee-for-service basis. This chartbook also supplements recent issue briefs focusing on the quality and completeness of encounter data. It provides valuable information for CMS and researchers on the availability of and uses for encounter data in MAX data.
