When you can enroll. The initial enrollment period for Medicare consists of the three months before, the month of, and the three months after your 65th birthday. If you want your coverage to start the month you turn 65, sign up during that first three-month period.
Most Americans become eligible for Medicare at age 65, and sign up for Medicare during their Initial Enrollment Period. If you enroll during your Initial Enrollment Period, you should receive your first Medicare card in the mail within about 30 days. Even if you are not new to Medicare, there may be times you need to apply for a new Medicare card.
