After your Initial Enrollment Period is over, you may have a chance to sign up for Medicare during a Special Enrollment Period. For example, if you didn’t sign up for Part B (or Part A if you have to buy it) when you were first eligible because you have group health plan coverage based on current employment (your own, a spouse’s, or a family member’s if you have a disability), you can sign up for Part A and/or Part B:

  • Any time you’re still covered by the group health plan
  • During the 8-month period that begins the month after the employment ends or the coverage ends, whichever happens first
