Which of the following is NOT covered by Medicare Part A?

Medicare Part A primarily covers inpatient services. This includes costs associated with hospital stays, skilled nursing facilities (after a qualifying hospital stay), hospice care, and some home health care services, but typically only if the patient is homebound and requires skilled nursing care or therapy services.

Outside patient services, often referred to as outpatient care, are not covered under Medicare Part A. Instead, outpatient services are generally covered under Medicare Part B, which includes services such as doctor visits, diagnostic tests, and outpatient hospital services. Thus, recognizing that outpatient services fall under Part B rather than Part A establishes why this option is the correct answer in the context of Medicare coverage elements.
