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 market-based 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 84% of Americans have health insurance; some 60% obtain it through an employer, while about 9% purchase it directly. Various government agencies provide coverage to about 27% of Americans (there is some overlap in these figures).

In 2006, there were 47 million people in the US (16% 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.

Public health care coverage
Public programs provide the primary source of coverage for most seniors and for low-income children and families who meet certain eligibility requirements. The primary public programs are Medicare, a federal social insurance program for seniors and certain disabled individuals, Medicaid, funded jointly by the federal government and states but administered at the state level, which covers certain very low income children and their families, and SCHIP, also a federal-state partnership that serves certain children and families who do not qualify for Medicaid but who cannot afford private coverage. Other public programs include military health benefits provided through TRICARE and the Veterans Health Administration and benefits provided through the Indian Health Service. Some states have additional programs for low-income individuals.

Health insurance

The term health insurance is generally used to describe a form of insurance that pays for medical expenses. It is sometimes used more broadly to include insurance covering disability or long-term nursing or custodial care needs. It may be provided through a government-sponsored social insurance program, or from private insurance companies. It may be purchased on a group basis (e.g., by a firm to cover its employees) or purchased by individual consumers. In each case, the covered groups or individuals pay premiums or taxes to help protect themselves from high or unexpected healthcare expenses. Similar benefits paying for medical expenses may also be provided through social welfare programs funded by the government.

Health insurance works by estimating the overall risk of healthcare expenses and developing a routine finance structure (such as a monthly premium or annual tax) that will ensure that money is available to pay for the healthcare benefits specified in the insurance agreement. The benefit is administered by a central organization, most often either a government agency or a private or not-for-profit entity operating a health plan.

History of insurance
The concept of health insurance was proposed in 1694 by Hugh the Elder Chamberlen from the Peter Chamberlen family. In the late 19th century, "accident insurance" began to be available, which operated much like modern disability insurance.[2].This payment model continued until the start of the 20th century in some jurisdictions (like California), where all laws regulating health insurance actually referred to disability insurance.[3]

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.[4]

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 beginning in 1929, through the 1930s and on during World War II
