Are you confused thinking you need to renew your Medicare Supplement policy? Your policy is in fact guaranteed renewable. That means that as long as you are current on paying the premium that your insurance coverage will renew automatically. Just because we are entering the Annual Enrollment Period (AEP) does not mean that you need to take action to renew your Medicare Supplement policy. It is always important to have your supplement reviewed annually, but generally your renewal does not occur until your birthday month when you aged into Medicare for most of you.
