Medicare — Medicaid Eligibility Type Code: Annual Dual Eligibility Status

SAS Name
MME_TYPE_CD

This variable is the annual indicator of the beneficiary’s Medicare-Medicaid eligibility type code. CCW creates this variable using a hierarchy that is the maximum value of the monthly MME_TYPE_CD_MM.

Comments

MMLEADS also includes the monthly MME_TYPE_CD_01–12

If the beneficiary has more than one MME_TYPE_CD_01–12 value during the year, then CCW uses the maximum value of the monthly MME_TYPE_CD_MM. The hierarchy (and definition of the MME_TYPE_CD) is:

Full dual (MME_TYPE_CD = 4) — the MBSF DUAL_STUS_CD_MM in ('02' '04' '08');

Partial dual (MME_TYPE_CD = 3) — the MBSF DUAL_STUS_CD_MM in ('01' '03' '05' '06');

Medicare only (MME_TYPE_CD = 2) — the MBSF DUAL_STUS_CD_MM = '00' '09' 'N/A' 'NA' '99' and MDCR_BUY_IN in ('1' '2' '3' 'A' 'B' 'C') then (Medicare Only); or else if
