Health insurance in the United States

The term health insurance is commonly used in the United States to describe any program that helps pay for medical expenses, whether through privately purchased insurance, social insurance or a non-insurance social welfare program funded by the government. Synonyms for this usage include "health coverage," "health care coverage" and "health benefits."

In a more technical sense, the term is used to describe any form of insurance that provides protection against injury or illness. This usage includes private insurance and social insurance programs such as Medicare, but excludes social welfare programs such as Medicaid. In addition to medical expense insurance, it also includes insurance covering disability or long-term nursing or custodial care needs.

The US health care system relies heavily on private and not-for-profit health insurance, which is the primary source of coverage for most Americans. According to the United States Census Bureau, approximately 85% of Americans have health insurance; nearly 60% obtain it through an employer, while about 9% purchase it directly. Various government agencies provide coverage to about 28% of Americans (there is some overlap in these figures).

In 2007, there were nearly 46 million people in the US (over 15% of the population) who were without health insurance for at least part of that year. The percentage of the non-elderly population who are uninsured has been generally increasing since the year 2000. There is considerable debate in the US on the causes of and possible remedies for this level of uninsurance as well as the impact it has on the overall US health care system (see Health care reform in the United States

History

Accident insurance was first offered in the United States by the Franklin Health Assurance Company of Massachusetts. This firm, founded in 1850, offered insurance against injuries arising from railroad and steamboat accidents. Sixty organizations were offering accident insurance in the US by 1866, but the industry consolidated rapidly soon thereafter. While there were earlier experiments, the origins of sickness coverage in the US effectively date from 1890. The first employer-sponsored group disability policy was issued in 1911.

Before the development of medical expense insurance, patients were expected to pay all other health care costs out of their own pockets, under what is known as the fee-for-service business model. During the middle to late 20th century, traditional disability insurance evolved into modern health insurance programs. Today, most comprehensive private health insurance programs cover the cost of routine, preventive, and emergency health care procedures, and also most prescription drugs, but this was not always the case.

Hospital and medical expense policies were introduced during the first half of the 20th century. During the 1920s, individual hospitals began offering services to individuals on a pre-paid basis, eventually leading to the development of Blue Cross organizations.^[4] The predecessors of today's health maintenance organizations (HMOs) originated in 1929, through the 1930s and on during World War II
