The Medicare Advantage Disenrollment Period (MADP) begins Jan. 1, 2018, and runs through Feb. 14, 2018. During this time, Medicare Advantage enrollees may choose to disenroll from a Medicare Advantage plan. If they choose to disenroll from a Medicare Advantage plan, they will return to Original Medicare for health coverage and have an opportunity to enroll into a prescription drug plan for Part D coverage.

This special election period permits one enrollment and ends when an individual enrolls in a prescription drug plan. Enrollment requests made in January have a Feb. 1 effective date and enrollment requests made in February have a March 1 effective date. No other changes are permitted during the MADP.
