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. Medicare:In the United States, Medicare is a federal social insurance program that provides health insurance to elderly workers and their dependents, individuals who become totally and permanently disabled, and end stage renal disease (ESRD) patients.

Some health care economists (Uwe Reinhardt of Princeton and Stuart Butler among others) assert that the third-party payment feature of this program has had the unintended consequence of distorting the price of medical procedures. As a result, the Health Care Financing Administration has set up a list of procedures and corresponding prices under the Resource-Based Relative Value Scale. Recent research has found that the health trends of previously uninsured adults, especially those with chronic health problems, improves once they enter the Medicare program. Medicare Advantage:Medicare Advantage plans expand the health care options for Medicare beneficiaries. The option for Medicare Advantage plans is a result of the Balanced Budget Act of 1997, with the intent to better control the rapid growth in Medicare spending, as well as to provide Medicare beneficiaries more choices. Medicare Part D (Prescription Drugs):Medicare Part D provides a private insurance option to allow Medicare beneficiaries to purchase subsidized coverage for the costs of prescription drugs.

It was enacted as part of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) and went into effect on January 1, 2006. Medicaid:Medicaid was instituted for the very poor in 1965. Despite its establishment, the percentage of US residents who lack any form of health insurance has increased since 1994. It has been reported that the number of physicians accepting Medicaid has decreased in recent years due to relatively high administrative costs and low reimbursements. Medicaid is a social welfare or social protection program rather than a social insurance program. State Children's Health Insurance Program (SCHIP):The State Children’s Health Insurance Program (SCHIP) is a joint state/federal program to provide health insurance to children in families who earn too much money to qualify for Medicaid, yet cannot afford to buy private insurance. The statutory authority for SCHIP is under title XXI of the Social Security Act.


 

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. 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. The predecessors of today's health maintenance organizations (HMOs) originated in 1929, through the 1930s and on during World War II.
