This variable is the number of months during the year that the beneficiary was enrolled in an employer-sponsored prescription drug plan that qualified for Part D’s retiree drug subsidy (RDS). CCW derives this variable by counting the number of months where the beneficiary had retiree drug subsidy.
A month of RDS is when the RDS_IND_XX for the month = Y.
Some employers offer prescription drug plans to their retirees, and Part D pays a subsidy to plans that offer coverage that is equivalent to (or better than) conventional Part D benefits.
CMS does not collect PDEs for beneficiaries that are enrolled in RDS-eligible plans.
