Medicare Part B is voluntary and covers physician services.

• A. It is voluntary and covers physician services
• B. It covers inpatient hospital care
• C. It covers prescription drugs only
• D. It is free for all seniors

Answer: (A)

Medicare Part B provides optional medical insurance for outpatient services, including physician visits and many other outpatient care items. The key point is that enrollment in Part B is voluntary and requires paying a monthly premium, with potential penalties if you delay enrollment. It does not cover inpatient hospital care (that’s Part A) and it does not primarily cover prescription drugs (that’s Part D). So describing Part B as voluntary and covering physician services correctly captures how this part works.
