When Can I Change My Medigap Policy? 
You can change your Medigap policy at any time during the year . Medigap plans are not restricted to the Annual Enrollment Period -LRB- AEP - Oct 15-Dec 7 each year -RRB- . If you 're outside your initial open enrollment period when you first enrolled in Medicare Part A & Part B and are not eligible for a guaranteed-issue right , then you will have to go through medical underwriting -LRB- answering yes/no health questions - there are no exams for Medigap plans -RRB- . I hope the information is helpful - please feel free to call me if you have any questions about Medigap plans , including quotes and plan comparisons , and if you have any other questions . Thanks very much .
