On the whole, uninsured Americans have worse health outcomes; cancers and other deadly diseases, for example, are more likely to be diagnosed at later stages in uninsured people. Uninsured pregnant women use fewer prenatal services and uninsured children and adults are less likely than their insured counterparts to have a primary care doctor whom they trust.
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.
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.
Individual and family health insurance plans can help cover expenses in the case of serious medical emergencies, and help you and your family stay on top of preventative health-care services. Having health insurance coverage can save you money on doctor's visits, prescriptions drugs, preventative care and other health-care services. Typical health insurance plans for individuals include costs such as a monthly premium, annual deductible, copayments, and coinsurance.
