Which of the following services is NOT covered by Medicare Part B?

Medicare Part B primarily focuses on coverage for outpatient services, which includes a variety of medical services necessary for diagnosis, treatment, and prevention of illnesses. This part of Medicare covers surgical services, outpatient therapy, and diagnostic tests, all of which fall under the realm of medical services provided outside of a hospital setting.

Long-term nursing home care is not covered by Medicare Part B, as this type of care is generally classified as custodial care, which is not included in the benefits provided by this part of Medicare. Medicare Part A, which covers inpatient hospital stays, would be the relevant part for any short-term stays in a skilled nursing facility, rather than long-term care, which typically involves assistance with daily activities rather than skilled nursing care.

In summary, recognizing that long-term nursing home care does not align with the coverage type that Medicare Part B offers is crucial, as it highlights the distinction between various types of care and how they are classified under different parts of Medicare.
