This is a volatile time for health insurance policy. Medicare and Medicaid are in turmoil, as is the private health insurance market. Public and private health insurance costs constitute eighty percent of healthcare spending in the United States. Public health professionals depend on the insurance system to behave in ways that are responsive to public health in prevention and crisis management.

Seventy-five percent of the American population, excluding the elderly, has coverage through the private health insurance system. Ninety percent of this group receives their insurance through employer-sponsored programs, and the remaining ten percent buy their own coverage. Approximately ten percent of the non-elderly population has insurance through a government program, and fifteen percent of the non-elderly population, almost forty-one million Americans, is uninsured.
