When can I apply for a Medicare supplement (Medigap)?
There is no “season”; you can apply for a Medigap supplement policy at any time. However, insurance companies generally may increase your starting premium because of your medical history (underwrite) and don’t have to issue you a policy. You have “guaranteed issue” (they may neither deny nor underwrite) during your six-month Medigap open enrollment period. This period begins the day your Part B starts and lasts for six months. This is the time to buy into this insurance if you want to try it.
