When Is The Medigap Open Enrollment Period? 
If you already have a Medigap Plan then you do n't have to wait for any special enrollment period to look at other plans . You can switch plans anytime of the year it benefits you . One of the many great things about Medigap Plans . This is very commonly misunderstood because of all the advertising that is done in the fall leading people to believe they can only change their Medigap Plan during that time . If you are turning 65 and signing up for Medicare Part B for the first time then you get a one time `` open enrollment period '' for 6 months . This means the agent will not need to complete any of the health questions on the application and there is basically no underwriting to go through . I would be happy to answer any other questions you have .
