Medigap plans should not be marketed to individuals enrolled in Medicare Advantage Plans unless they intend to revert to Original Medicare. If anyone attempts to market you a Medigap plan without your intent to terminate your Medicare Advantage plan, this should be reported to your state’s insurance department.
Should you possess a Medigap plan and decide to enroll in a Medicare Advantage Plan, it may be wise to cancel your Medigap plan. Medigap plans will not cover the extra cost-sharing associated with Medicare Advantage Plans, such as copayments, deductibles, or premiums.
If you fail to terminate your Medicare Advantage Plan and switch back to Original Medicare within a year of enrollment, you typically are required to maintain your Medicare Advantage Plan for the remainder of the calendar year. You retain the option to withdraw or switch plans either during the Open Enrollment Period or if you become eligible for a Special Enrollment Period. However, your entitlement to procure a Medigap policy can be influenced by the specific terms of the Special Enrollment Period.
