Which of the following best describes eligibility requirements to enroll in a Medicare Advantage (MA) plan?

• A. Entitled to Part A and enrolled in Part B, live in the plan's service area, may have pre-existing conditions such as ESRD.
• B. Only individuals without ESRD can enroll.
• C. Requires enrollment in Part D before MA.
• D. Must reside outside the service area.

Answer: (A)

Eligibility for a Medicare Advantage plan is based on three things: you must be entitled to Medicare Part A and enrolled in Part B, you must live in the plan’s service area, and having a condition like ESRD does not automatically disqualify you. ESRD is allowed, so you can enroll even if you have it. You don’t have to enroll in Part D before joining MA, since many MA plans include drug coverage (or you can add Part D if your plan doesn’t). The key point is meeting Part A/B and service-area requirements; residing outside the service area or lacking Part A/B would prevent enrollment.
