The US has a joint federal and state system for regulating insurance, with the federal government ceding primary responsibility to the states under the McCarran-Ferguson Act. States regulate the content of health insurance policies and often require coverage of specific types of medical services or health care providers. State mandates generally do not apply to the health plans offered by large employers, because of the preemption clause of the Employee Retirement Income Security Act.

Through the 1990s, managed care insurance schemes including health maintenance organizations (HMO), preferred provider organizations, or point of service plans grew from about 25% US employees with employer-sponsored coverage to the vast majority. With managed care, insurers use various techniques to address costs and improve quality, including negotiation of prices ("in-network" providers), utilization management, and requirements for quality assurance such as being accredited by accreditation schemes such as the Joint Commission and the American Accreditation Healthcare Commission.
Employer-sponsored health insurance plans dramatically expanded as a direct result of wage controls imposed by the federal government during World War II. The labor market was tight because of the increased demand for goods and decreased supply of workers during the war. Federally imposed wage and price controls prohibited manufacturers and other employers from raising wages enough to attract workers. When the War Labor Board declared that fringe benefits, such as sick leave and health insurance, did not count as wages for the purpose of wage controls, employers responded with significantly increased offers of fringe benefits, especially health care coverage, to attract workers.
The share of Americans without health insurance has been cut in half since 2013. Many of the reforms instituted by the Affordable Care Act of 2010 were designed to extend health care coverage to those without it; however, high cost growth continues unabated. National health expenditures are projected to grow 4.7% per person per year from 2016 to 2025. Public healthcare spending was 29% of federal mandated spending in 1990 and 35% of it in 2000. It is also projected to be roughly half in 2025.
