Which additional benefit is often included in Medicare Advantage plans?

Medicare Advantage plans, also known as Medicare Part C, often include prescription drug coverage as an additional benefit. This integration becomes particularly beneficial for enrollees who require medication as it simplifies their healthcare management by allowing them to receive all their Medicare benefits, including drug coverage, through a single plan. This consolidation can lead to lower overall costs and streamlined access to healthcare services.

While other options may sound appealing, they typically are not guaranteed benefits provided by Medicare Advantage plans. Extended hospital stay coverage, free elective surgeries, and complete waiving of out-of-pocket expenses are not standard offerings and can vary widely between different plans and providers. Thus, prescription drug coverage is commonly included as a feature of these plans, making it the correct answer.
