Which of the following describes a Medicare Advantage Plan?

A Medicare Advantage Plan refers to a type of health insurance plan offered by private companies that provides an alternative way for beneficiaries to receive their Medicare benefits. These plans are required to cover all services provided by Original Medicare (Parts A and B), which include hospital care, doctor services, preventive care, and other medically necessary services.

In addition to the coverage equivalent to Original Medicare, many Medicare Advantage Plans also offer additional benefits, such as vision, dental, and wellness programs, which are not included in the standard Medicare coverage. This comprehensive nature of Medicare Advantage Plans is what distinguishes them, making option C the correct choice.

The other options describe aspects that do not accurately represent the full scope of Medicare Advantage Plans. For instance, a plan that only includes drug coverage pertains to Medicare Part D, which is separate from the advantage plan. A program providing supplemental income is unrelated to Medicare altogether. Finally, a standalone policy that covers only hospital care aligns more closely with certain aspects of Original Medicare rather than a Medicare Advantage Plan itself.
