Medicare Part A and Part B Enrolled Months

SAS Name
MDCR_PTAPTB_MOS

This variable is the number of months during the year that the beneficiary had both Medicare Part A and Part B coverage.

Comments

CCW creates this variable using the MBSF monthly Medicare entitlement buy-in variable. We count the months when any value indicates Part A coverage (i.e., where MDCR_ENTLMT_BUY_IND_MM in ('3' 'C').

Within MMLEADS we include this monthly Medicare Entitlement/Buy-In Indicator variable as MDCR_BUYIN_01–12.

Values: 0-12, or null/missing (if no Medicare enrollment)
