In terms of hospital stay coverage, which part of Medicare assists Joseph, who only has Original Medicare?

Joseph, who has Original Medicare, would be covered for hospital stays by Medicare Part A. This part of Medicare is specifically designed to cover inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care. When a patient is admitted to a hospital, Part A will typically cover the costs associated with the stay, including room, board, and necessary hospital supplies and services for a set number of days.

In contrast, Part B focuses on outpatient care, preventive services, and some doctor services, while Part C, also known as Medicare Advantage, is a plan that includes both Part A and Part B benefits, and often extra benefits as well. Part D provides coverage for prescription drugs. Since Joseph only has Original Medicare, the crucial role of assisting with hospital stay coverage falls under Part A, making it the correct answer.
