Months of Dual Eligibility

SAS Name

This variable is the number of months during the year that the beneficiary was dually eligible (i.e., he/she was also eligible for Medicaid benefits).


CCW derived this variable by counting the number of months where the beneficiary had dual eligibility (i.e., months where DUAL_STUS_CD_XX equal to '01', '02', '03', '04', '05', '06', '08', '09', or '99').

There are different ways to classify dually eligible beneficiaries — in terms of whether he/she is enrolled in full or partial benefits. Additional information regarding various ways to identify dually enrolled populations, refer to a CCW Technical Guidance document entitled: "Options in Determining Dual Eligibles."
