The answer is NO - if what you have is a supplement. The open enrollment period at the end of the year applies to Medicare Advantage Plans and prescription drug plans. If you have a supplement, you can apply to another company at any time.
If you have a Medicare Advantage Plan and want to make a change, you must wait until the Open Enrollment between October 15 and December 7, unless you qualify for a Special Election Period. If you think this might apply to you - give us a call at 888-565-9556 and we'll be happy to provide information to see if you qualify.
There is also a Medicare Advantage disenrollment period from Jan 1 to February 14.here to edit.
