What should you advise Mrs. Lopez about enrolling in a Medicare Part D plan after losing creditable coverage?

Mrs. Lopez should be informed that, upon losing creditable prescription drug coverage, she is eligible to enroll in a Medicare Part D plan. This can either be a standalone prescription drug plan (PDP) or a prescription drug benefit that is part of a Medicare Advantage Plan. The loss of creditable coverage qualifies her for a Special Enrollment Period, allowing her to sign up for Part D coverage without facing any late enrollment penalties, provided she enrolls in a timely manner.

This option is correct because it acknowledges her eligibility and the choices available to her directly following the loss of her previous coverage. It empowers Mrs. Lopez with options for managing her prescription drug needs effectively. Awareness of these options is crucial for her to maintain necessary coverage and avoid gaps in her medication access.
