CCW obtains this directly from the MBSF DUAL_STUS_CD_01–12 variables.
The original source for this variable is the State Medicare Modernization Act (MMA) files that states submit to CMS. Those files are considered the “gold standard” for identifying dual eligibles because the information in them is used to determine the level of Medicare Part D low-income subsidies.
