Medicare-Medicaid Dual Eligibility Code - April

SAS Name
DUAL_ELGBL_CD_04

Indicates coverage for beneficiaries entitled to Medicare (Part A and/or B benefits) and eligible for some category of Medicaid benefits in the month (i.e., dually eligible). There are separate variables for each of the 12 months during the year.

Comments

Dual eligibles are often divided into “full duals” and “partial duals” based on the level of Medicaid benefits they receive. CMS generally considers beneficiaries to be full duals if they have values of 02, 04, or 08, and to be partial duals if they have values of 01, 03, 05, or 06. Partial duals are sometimes divided into the QMB-only population (01) and all other partial duals (03, 05, or 06). There are different ways to classify dually eligible beneficiaries.
