Will enrolling in a Medicare Supplement plan automatically disenroll an individual from a Medicare Advantage Plan?

Enrolling in a Medicare Supplement plan does not automatically disenroll an individual from a Medicare Advantage Plan. This is because Medicare Supplement plans, also known as Medigap plans, are designed to work alongside Original Medicare (Parts A and B) rather than with Medicare Advantage plans.

When an individual enrolls in a Medicare Advantage plan, they are essentially opting out of Original Medicare for the services covered under the Advantage plan. If they subsequently decide to enroll in a Medicare Supplement plan, they would need to first disenroll from their Medicare Advantage plan in order to have coverage from Medigap, as Medigap cannot be used to supplement Medicare Advantage plans.

Therefore, the correct understanding is that simply enrolling in a Medicare Supplement plan does not automatically result in a disenrollment from a Medicare Advantage plan; the individual has to take action to disenroll from the Medicare Advantage plan if they wish to switch to a Medicare Supplement.
