What can Aries do to change his PDP to a Medicare Advantage plan effective November 1?

The option that indicates Aries may be able to use a Special Election Period (SEP) if he qualifies is correct because certain life events or circumstances allow individuals to make changes to their Medicare Advantage plans outside the Annual Election Period. Events such as moving, losing current coverage, or significant changes in health can qualify an individual for a Special Election Period, giving them the opportunity to switch to a different Medicare Advantage plan, including one effective on November 1.

Understanding this aspect of Medicare enrollment is critical, as it ensures that beneficiaries can adapt their healthcare choices in response to changing personal circumstances, thereby enhancing their access to necessary medical services. The other options suggest limitations that do not take into account the flexibility provided by Special Election Periods, which are designed specifically to accommodate the dynamic needs of enrollees.
