Which coverage is provided under Medicare Part B?

Medicare Part B primarily covers outpatient services and is designed to help with the costs of medically necessary services, as well as certain preventive services aimed at detecting health issues early. One of the key components of Medicare Part B is its focus on routine preventive services, which can include vaccinations, annual wellness visits, and screenings for various conditions, such as cancer and heart disease. These services are essential for promoting health and preventing the progression of diseases, which aligns with Medicare's goal of helping beneficiaries maintain their health and well-being.

In contrast, inpatient hospital visits are typically covered under Medicare Part A, long-term care services are not covered under Medicare at all, and prescription drug coverage is generally associated with Medicare Part D. Therefore, the correct answer emphasizes the preventive aspect of Medicare Part B, highlighting its role in promoting health and early detection rather than providing coverage for inpatient care, long-term care, or prescription medications.
