Which statement is true about a Medicare Advantage Plan member enrolling in a Medicare Supplement Insurance Plan?

The statement that enrollment in a Medicare Supplement Insurance Plan does not automatically disenroll a member from their Medicare Advantage (MA) plan is accurate. This means that individuals can choose to switch to a Medicare Supplement plan without losing their MA plan coverage immediately.

Medicare Supplement plans are designed to work alongside Original Medicare, providing additional coverage for costs not fully covered by Medicare Parts A and B. Since Medicare Advantage plans are an alternative to Original Medicare, a member cannot have both an MA plan and a Medicare Supplement Insurance Plan at the same time. However, enrolling in the latter will not automatically terminate their coverage under the MA plan until they actively choose to do so or follow specific procedures.

This understanding is crucial for Medicare beneficiaries, as it highlights the importance of knowing how these plans interact and the potential need for written cancellation of the MA plan if they opt to transition to a Medicare Supplement plan. The other options present misconceptions about the enrollment process and the relationship between MA plans and Medicare Supplement policies.
