Who can join a Medicare Prescription Drug Plan?

If you have prescription drug coverage from a former or current employer or union, contact your benefits administrator before you make any changes to your drug coverage. If you join a Medicare Prescription Drug Plan or Medicare Advantage Plan, you and your family may lose your employer or union coverage.
