SNACC Phase IV Report

Publication Year: 
2009

Report for Phase 1 of the Medicaid Undercount Project (SNACC).  This phase involved re-using the Phase II process, replacing the CPS data with NHIS data.

SNACC Phase III Report

Publication Year: 
2008

Report for Phase III of the Medicaid Undercount Project (SNACC).  In this phase data from the state MSIS files, CPS, 2001 Supplemental Survey (SS01), as well as the MAX and Census Bureau Master Address File (MAF) were used.

Report for Phase II of the Medicaid Undercount Project (SNACC). In this phase data were merged from the Medicaid Analytic Extract (MAX), MSIS, the Current Population Survey (CPS), the Person Characteristic File (PCF), and the Master Address File Auxiliary Reference File (MAFARF). Once matches/non-matches between the MSIS and CPS were determined, the matched records were supplemented with information from the MAX and examine why there were discrepancies between MSIS records of enrollment and CPS reports of Medicaid coverage. The MAFARF and PCF are used to augment the analysis.
