1 When you turn 65 (and have no other drug coverage that is as good as Medicare), you need to join a Part D drug plan during the 7-month initial enrollment period when you can sign up for Medicare Part A and Part B. This period runs from three months before the month of your 65th birthday to three months after it.f your coverage is not creditable, you can still keep it. But if you sign up for a Medicare drug plan at some future date, and you have gone for more than 63 days without creditable coverage, you would then pay a late penalty.
You can sign up for Medicare Parts A & B between January 1 and March 31 each year. Your Medicare coverage would begin on July 1 of the same year. It is important to note that if you need to buy Part A, you must also enroll in Part B at this time.ou can get a Special Enrollment Period to sign up for Part C (must enroll in Parts A & B too): 1  During the 63 days after the employer or union group health plan coverage ends, or when the employment ends (whichever is first).
