Which of the following statements is true about eligibility requirements for stand-alone Medicare prescription drug plans?

The eligibility requirement that a consumer must be entitled to Medicare Part A and/or enrolled in Medicare Part B is accurate because it reflects the fundamental criteria established by Medicare for participation in stand-alone prescription drug plans.

To enroll in a stand-alone Medicare prescription drug plan, individuals need to be eligible for Medicare, which can be accomplished in two ways: being entitled to Medicare Part A, which usually occurs when one reaches age 65 or meets specific disability criteria, or being enrolled in Medicare Part B, which covers outpatient care. This means that the requirement to either have Part A or Part B ensures that the individual has basic coverage through Medicare, linking their eligibility for additional drug benefits to their existing Medicare status.

The other options present different scenarios that do not capture the full spectrum of eligibility. For instance, requiring a specific age, only those with disabilities, or having a Social Security number limits the understanding of who can qualify for these plans, while the correct option encompasses all eligible individuals under Medicare.
