Who is eligible for a stand-alone Medicare Prescription Drug Plan?

A stand-alone Medicare Prescription Drug Plan (PDP) is specifically designed for individuals who are enrolled in Medicare and requires them to be enrolled either in Medicare Part A, Part B, or both. The correct response highlights a scenario where Joseph is enrolled in both Medicare Part A and Part B, which fulfills the eligibility criteria for a stand-alone PDP.

In order to enroll in a stand-alone Medicare Prescription Drug Plan, individuals must be part of the Medicare program. This means they must have either Part A or Part B coverage, which allows them to access the prescription drug coverage provided through the PDP.

Individuals who are solely enrolled in Medicare Part B or have other types of private insurance plans do not meet the eligibility requirement for a stand-alone PDP. Similarly, those who are not legal residents would also not qualify, since Medicare services are generally available only to U.S. citizens or lawful permanent residents. Thus, Joseph's enrollment in both Parts A and B clearly makes him eligible to enroll in a stand-alone Medicare Prescription Drug Plan.
