Which category accounts for the largest share of healthcare expenditures in the United States?

• A. Hospital care
• B. Physician services
• C. Prescription drugs
• D. Long-term care

Answer: (A)

The main idea is understanding how health spending is distributed across sectors and which sector drives the most dollars. In the United States, hospital care typically accounts for the largest share of expenditures because inpatient stays, surgeries, emergency and facility-based services, and the use of expensive medical technology carry high costs. Hospitals have substantial fixed costs—buildings, staff, equipment—that must be covered, and many services are billed as facility charges, which tend to be higher than outpatient equivalents. While physician services, prescription drugs, and long-term care are large and important components of total health spending, their combined share generally remains smaller than that of hospital care.
