What is the primary function of public health insurance?

The primary function of public health insurance is to provide coverage for the uninsured. Public health insurance programs are designed to ensure that individuals who may not have access to private insurance or financial resources to purchase healthcare services can receive necessary medical care. This is crucial in promoting public health and ensuring that health disparities are reduced within the population. By offering coverage to those without insurance, public health programs can also facilitate preventive care, reduce emergency healthcare costs, and improve overall community health outcomes.

The other options emphasize different aspects of health insurance that do not align with the primary goal of public health insurance. For instance, maximizing corporate profit primarily reflects the focus of private sector health insurance rather than public programs. Employer-sponsored plans address coverage through job-related benefits but don't encompass the broader objective of public health initiatives. Restricting services to private insurers would contradict the inclusive nature of public health insurance, which aims to expand access rather than limit it.
