What is Medicare open enrollment?

In October, you'll start hearing a lot about the annual Medicare open enrollment period. It is a time when existing Medicare enrollees can make changes to their coverage.

During this time, you can do the following things:

* Enroll in a Medicare Part D (drug coverage) plan

* Change from one Medicare Part D plan to another

* Cancel a Medicare Part D plan

* Switch from Medicare Advantage to original Medicare

* Enroll in a Medicare Advantage plan

* Change from one Medicare Advantage plan to another

* Enroll in a Medicare supplement plan if you want to switch from Medicare Advantage to original Medicare, Parts A (hospital) and B (medical).

The annual open enrollment period runs from Oct. 15 through Dec. 17.

If you are on a Medicare Advantage plan, you may want to review what plans are available. Selections change each year and some may be better suited to your current medical or financial status.
