Final answer:
Medicare Part B covers preventive health services. It is part of the Medicare program which assists with the cost of non-hospital medical care, including physicians' services, outpatient visits, and durable medical equipment prescribed by a doctor.
Step-by-step explanation:
The question concerns which services are covered under Medicare Part B. Of the options provided, preventive health services are covered by Medicare Part B. This part of Medicare is an optional insurance program that focuses on non-hospital medical care, including physician services, medical tests, and outpatient visits. People who are part of this program pay a monthly premium, deductibles, and copayments, while the government funds the majority of the expenses. Therefore, services like skilled nursing home and hospice services fall under Medicare Part A or possibly other programs. Durable medical equipment is also covered by Medicare Part B as long as the equipment is medically necessary and prescribed by a doctor.
