Medicaid Analytic eXtract
Medicaid Analytic eXtract
(MAX - successor to SMRF)
Description
The Medicaid Analytic eXtract (MAX) data – formerly known as State Medicaid
Research Files (SMRFs) – are a set of person-level data files on Medicaid
eligibility, service utilization, and payments. 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 this final action event. Unlike fiscal-based MSIS quarterly files,
MAX are annual calendar year files. There are a number of other “value
added” enhancements to the MAX data for users, described in greater detail
through this link.
Availability
Because MAX data are derived from MSIS, and because it is necessary to allow
for the delay between service delivery dates and claims adjudication dates,
the availability of MAX data for a particular time period lags behind that of
the MSIS data. Since the MAX data contain individually identifiable data, they
are protected under the Privacy Act. They are available for approved research
activities only through a Data Use Agreement (DUA) with CMS.
Note that only approved academic research projects and certain government agencies
are entitled to a DUA to obtain MAX data. For information on applying for a
DUA, click here.
Introduction to Medicaid Analytic eXtract (MAX) Data (14 slides)
This is a PowerPoint presentation on the Medicaid Analytic eXtract (MAX) data

Presents the source and an overview of MAX data;
Describes five types of MAX data sets;
Explains the need for MAX data;
