Enrollment Periods

If you are aging into Medicare, it’s important for you to know when to enroll. There are two main enrollment periods: Initial and General.

When can I enroll?

  • Initial Enrollment Period

    The Initial Enrollment Period for Medicare Parts A and B begins three months before and ends three months after your 65th birthday.

  • General Enrollment Period

    If you do not enroll in Medicare Parts A and B during the Initial Enrollment period, you have the opportunity to enroll during the general enrollment period, which runs from Jan. 1 through March 31 each year. Coverage will begin the following July.

  • Special Enrollment Period

    There is a third period, called Special Enrollment Period, that applies if you are 65 or older and your coverage is ending through an employer (either your own or through a spouse).
