Is There Open Enrollment For Medigap? 
Every Medicare Beneficiary gets a 6 month period when you are allowed to buy any Medigap Plan that 's sold in your state . This Open Enrollment Period starts in the first month your ' e covered under Medicare Part B , AND you 're 65 or older . This Open Enrollment Period is only available one time . It 's a great opportunity to get a Medigap Plan during this time because you ca n't be denied a Policy due to current or past health conditions . If you 've been on Medicare Part B for more than 6 months , then you are out of the initial Open Enrollment Period . However , you CAN still apply for a Medigap Plan -- you 'll just have to answer the health questions on the application . If you already have Medigap coverage and want to switch Medigap Plans , you can apply for a new Plan any time of the year . Since there are many moving parts to Medicare , you may benefit from speaking with an agent who specializes in Medicare Supplement insurance . I am happy to help you with your specific situation .
