Which of the following is a benefit of Medicare Part B?

Medicare Part B offers a range of services, but one of its key benefits is the coverage of preventive screening services. This aspect is crucial as it focuses on preventing illness and managing health proactively rather than waiting for serious health issues to arise. Services covered through Medicare Part B include vaccines, screenings for various diseases (such as cancer screenings and cardiovascular disease), and annual wellness visits.

Preventive services help in early detection and can lead to better health outcomes, reducing the need for more severe medical interventions down the line. This preventive approach not only benefits beneficiaries by maintaining their health but also aids in controlling healthcare costs by reducing the incidence of advanced-stage diseases that require more extensive treatment options.

While the other provided choices may pertain to different aspects of healthcare coverage, they do not specifically fall under the preventive services that are a hallmark of Medicare Part B.
