Can You Switch From Medicare Advantage To Medigap? 
Yes . Generally , if you 're on Medicare Advantage , you can only apply for a Medigap plan during the annual enrollment period -LRB- October 15-December 7 -RRB- because this is the time when you 're able to leave your Medicare Advantage plan . You would be subject to the medical underwriting process -LRB- answering the health questions on a Medigap plan application -RRB- . To buy a Medigap plan without medical underwriting , you would need to qualify for a guaranteed-issue right . In the case of when you have Medicare Advantage , you would have to meet one of the following conditions : 1 -RRB- You have a Medicare Advantage plan and your plan is leaving Medicare , stops servicing your area , or you move out of the plan 's service area . Please note , you have to go back to original Medicare -LRB- Part A & B -RRB- coverage to qualify for this guaranteed-issue right . 2 -RRB- You joined a Medicare Advantage plan when you were first eligible for Medicare Part A at age 65 and within the first year of joining , you decide you want to switch to original Medicare -LRB- known as a `` trial right '' -RRB- . 3 -RRB- You dropped a Medigap policy to join a Medicare Advantage plan for the first time , have been in the plan less than a year , and you want to switch back -LRB- this is another type of `` trial right '' -RRB- . 4 -RRB- You leave a Medicare Advantage plan because the company has n't followed the rules , or it misled you . These 4 items are from Medicare 's website and can be found in your Medicare & You guidebook - copies are available on the Medicare.gov website -LRB- I can also e-mail you one if needed -RRB- .
