Important Medicare Dates

When can I join, switch, or drop a plan?


You can join, switch, or drop a Medicare health plan or a Medicare Advantage Plan (Part C) with or without drug coverage during these times:

  • Initial Enrollment Period. When you first become eligible for Medicare, you can join a plan (see page 17).
  • Open Enrollment Period. From October 15 – December 7 each year, you can join, switch, or drop a plan. Your coverage will begin on January 1 (as long as the plan gets your request by December 7).
  • Medicare Advantage Open Enrollment Period. From January 1 – March 31 each year, if you’re enrolled in a Medicare Advantage Plan, you can switch to a different Medicare Advantage Plan or switch to Original Medicare (and join a separate Medicare drug plan) once during this time.
