Which of the following is true of Medicare Part B?

Medicare Part B is designed to cover outpatient services, which includes doctor visits, preventive services, and some home health care. The funding for Medicare Part B comes from two primary sources: general federal revenue and premiums paid by beneficiaries. This combination of funding means that beneficiaries contribute to the program through their premiums, which underscores the elective nature of the coverage—individuals can choose to enroll in Part B, although most people do because it covers essential medical services.

The other options incorrectly describe aspects of Medicare Part B. It does not provide inpatient services, which are covered by Medicare Part A. Additionally, while many people do not pay a premium for Part A based on their work history, Part B typically requires a monthly premium. Lastly, routine dental checkups are generally not included in Medicare coverage, illustrating the need for awareness of the specific services that each Part of Medicare provides.
