Which two requirements must Larry meet to enroll in a Medicare Advantage plan with end-stage renal disease?

To enroll in a Medicare Advantage plan when an individual has end-stage renal disease (ESRD), they must be entitled to Medicare Part A and reside in the plan's service area.

Being entitled to Medicare Part A is essential because Medicare Advantage plans are offered by private insurance companies that provide Medicare benefits, and eligibility for these plans requires enrollment in Medicare Part A. Additionally, residing in the plan's service area is crucial because Medicare Advantage plans are network-based. If a potential enrollee does not live within the boundaries specified by a particular plan, they cannot choose that plan for their coverage.

The other options do not accurately reflect the requirements for enrolling in a Medicare Advantage plan with ESRD. For instance, age and geographic constraints related to service areas are particularly relevant, but age alone does not determine eligibility for individuals under 65 in this context. Similarly, requirements regarding primary care physician and proximity to hospitals or possessing supplementary insurance coverage are not standard conditions for enrollment in Medicare Advantage plans for ESRD patients.
