Approximately what percentage of U.S. healthcare is financed privately?

The correct answer reflects that approximately 55% of U.S. healthcare is financed privately, which includes funding from sources such as employer-sponsored health insurance, individual health plans, and out-of-pocket payments by consumers. This figure highlights the significant role that private financing plays in the overall healthcare system, as it indicates that a majority of healthcare expenditures are funded outside of public programs like Medicare and Medicaid.

Understanding this percentage is crucial for grasping how the U.S. healthcare system operates, especially in distinguishing between the public and private sectors of healthcare financing. The other percentages mentioned in the options would not accurately represent the current landscape of healthcare financing in the United States, as they either overestimate or underestimate the role of private funding.
