What action must be taken for enrollment in Medicare Part D when leaving a Medicare Advantage plan?

When transitioning from a Medicare Advantage (MA) plan to a standalone Medicare Part D plan, it is crucial to ensure that the transition is smooth and that the coverage needs are adequately addressed. In this context, the correct action involves contacting the Medicare Advantage carrier first. This step is essential because it helps to confirm the details regarding the termination of the current MA plan and ensures a seamless switch to a Part D plan, as not all Medicare Advantage plans include prescription drug coverage.

By contacting the carrier, individuals can verify any specific requirements or potential consequences related to their current MA plan, including any enrollment periods that may apply. This preventative measure can help avoid gaps in prescription drug coverage and ensure compliance with Medicare regulations.

Other actions, such as reapplying for Medicare coverage, may not be necessary since individuals already have Medicare under their MA plan. Automatic enrollment is not a standard feature in this situation and typically requires proactive steps. Submitting a written request for enrollment, while sometimes necessary, should ideally follow confirmation and guidance from the MA plan provider to ensure everything aligns correctly.
