Yearly Open Enrollment Period

This is the period from October 15th to December 7th each year when you can change your Medicare Advantage or Medicare Part D Plan.  This is by far the most popular and talked about period of open enrollment, this is simply because it affects every Medicare recipient regardless of special situations.  If you do not specify a change in your current Part C or D plan then you will remain in the plan that you currently have.  If you wish to change your Advantage or Prescription Drug plan then you must sign up for a new plan during this yearly open enrollment period.  You do not need to do anything to be disenrolled from your previous plan, the switch will happen automatically.  It is important to reevaluate your Medicare Part C and D plan each year to ensure you do not overpay and have the best plan available.  Go to our How to Choose a Medicare Part D Plan webpage for a detailed description on how to use the website to find the best plan in your area.
