What services are covered under Medicare Part B?

The correct choice focuses on the services provided under Medicare Part B, which primarily covers outpatient care. This includes doctor visits, preventive services (such as screenings and vaccinations), and other necessary medical services not limited to hospital stays. Medicare Part B is designed to help beneficiaries pay for medically necessary services and some preventive services that help keep beneficiaries healthy.

In contrast, inpatient hospital care, skilled nursing facility care, and home health care fall under different parts of Medicare. Inpatient care is typically covered under Medicare Part A, which focuses on hospital and facility expenses. Skilled nursing facility care, like inpatient care, is also covered by Part A after a qualifying hospital stay. Home health care may be partially covered under Parts A and B, but specifics depend on the type of service provided and the conditions met. Therefore, the correct answer effectively encapsulates the specific and fundamental services associated with Medicare Part B.
