Which option allows for a return to Original Medicare within the first 12 months?

Disenrollment from a Medicare Advantage plan is the correct option that allows an individual to return to Original Medicare (Part A and Part B) within the first 12 months of enrollment. This feature is designed for beneficiaries who may find that the Medicare Advantage plan does not meet their needs, allowing them to switch back to Original Medicare during this initial period.

It is essential to understand that this option provides a safety net for beneficiaries, ensuring they can reassess their healthcare coverage shortly after enrolling in a Medicare Advantage plan. The choice to switch back is vital for those who experience changes in their healthcare needs or preferences that are not adequately addressed within their Advantage plan.

The other options refer to scenarios that might affect eligibility or coverage, but they do not directly provide a structured opportunity to revert to Original Medicare within the first year of Advantage plan enrollment. For example, an illness that affects eligibility could lead to changes in coverage, but it does not inherently allow for a return to Original Medicare as part of a structured enrollment period. Similarly, a change of residency or loss of prior coverage might impact coverage options but do not have the same provision for returning to Original Medicare within the specified time frame.
