What statement is true concerning Medicare prescription drug plans for those with Part A only?

Individuals with Medicare Part A only can enroll in Medicare prescription drug plans if they do not have comprehensive prescription drug coverage through an employer-sponsored health plan. If their employer plan provides drug coverage, they may not need to enroll in a separate drug plan because they would have their prescriptions covered through their employer. Therefore, the option correctly outlines that these individuals have the opportunity to obtain a Medicare prescription drug plan in the absence of prescription drug coverage through their employer.

Furthermore, the option correctly highlights the importance of being able to access additional coverage when it's not otherwise provided, ensuring that individuals with just Part A still have avenues for obtaining necessary prescription medications. This ability to enroll under specific circumstances allows for flexibility and accessibility in managing healthcare needs, particularly regarding medication access for those who may otherwise be limited by having only Part A coverage.
