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.
The best time to purchase Medicare Supplement insurance, also known as Medigap, is during your Medigap Open Enrollment Period. This period lasts six months and begins the first day of the month in which you are 65 or older and enrolled in Medicare Part B. So if you turn 65 on April 3 but donât join Medicare B until May 25, your Medigap Open Enrollment Period will start on June 1, which is the first day of the month in which you are both 65 and enrolled in Part B.
