Single-payer health care is the financing of the costs of delivering universal health care for an entire population through a single insurance pool out of which costs are met. There may be many contributors to the single pool (insured persons, employers, government etc.)

Single-payer health insurance collects all medical fees and then pays for all services through a single government (or government-related) source. In wealthy nations, this kind of publicly-managed health insurance is typically extended to all citizens and legal residents.

Australia's Medicare, Canada's Medicare, the United Kingdom's National Health Service, and Taiwan's National Health Insurance are examples of single-payer universal health care systems. Medicare in the United States is an example of a single-payer system for a specified, limited group of persons within a country.

Single-payer systems may contract for healthcare services from private organizations (as is the case in Canada) or may own and employ healthcare resources and personnel (as is the case in the United Kingdom). The term single-payer thus only describes the funding mechanism—referring to health care being paid for by a single public body from a single fund—and does not specify the type of delivery, or who doctors work for. Although the fund holder is usually the government, some forms of single-payer employ a public-private system.

Types and variations
Canada and Australia and most European countries have single-payer health insurance programs. These programs provide universal health care. The United States has U.S. Medicare but this system is only for senior citizens and some of the disabled. Government is increasingly involved in U.S. health care spending, paying about 45% of the $2.2 trillion the nation spent on individuals' medical care in 2004.However, studies have shown that the publicly-administered share of health spending in the U.S. is closer to 60%.

Single-payer healthcare may be operated in a number of ways. In some cases doctors may be employed, and hospitals run by, the government. This is the case in the United Kingdom, and is referred to in the US as socialized medicine. Alternatively the government may purchase healthcare services from outside organizations. This is the approach taken in Canada.

According to Princeton University health economist Uwe E. Reinhardt, U.S. Medicare, Medicaid, and SCHIP represent "forms of 'social insurance' coupled with a largely private health-care delivery system" rather than forms of "socialized medicine." In contrast, he describes the Veterans Administration healthcare system as a pure form of socialized medicine because it is "owned, operated and financed by government."

The Veterans Administration is a single-payer system and provides excellent quality, said Reinhardt. In a peer-reviewed paper published in the Annals of Internal Medicine, researchers of the RAND Corp. reported that the quality of care received by Veterans Administration patients scored significantly higher overall than did comparable metrics for patients currently using U.S. Medicare.

Some writers describe publicly administered health care systems as "single-payer plans." Some writers have described any system of health care which intends to cover the entire population, such as voucher plans, as "single-payer plans,"[7] although this is an uncommon usage. The standard usage refers to health insurance, as opposed to healthcare delivery, operating as a public service, like fire departments, community libraries, and other publicly-funded services, offered to citizens and legal residents towards providing near-universal or universal health care. The fund can be managed by the government directly or as a publicly owned and regulated agency.

Canada
Health care in Canada is an example of single-payer health care.[2] The national government provides part of the funding, provincial governments manage the hospitals and provide the bulk of the funding, and doctors in private practice contract with the government for fee-for-service payments. Although many Canadian citizens have supplemental private insurance from their employers, this covers non-medically necessary expenses not covered by Canadian Medicare, and accounts for only 12% of national health care spending.

Fees for doctors, hospitals and other providers are set by negotiations among doctors' associations, provincial or regional governments, and the national government.[citation needed] Global budgets eliminate the high potential costs (as is the case in the U.S.) of billing individually for huge numbers of products and services.[citation needed]

Health care provision in Canada is a mix of private and public services, although most hospitals are public. Patients may go to any doctor or hospital in the country.

Canadians do wait for some treatments and diagnostic services. Survey data shows that the median wait time to see a special physician is a little over four weeks with 89.5% waiting less than 3 months. The median wait time for diagnostic services such as MRI and CAT scans is two weeks with 86.4% waiting less than 3 months. The median wait time for surgery is four weeks with 82.2% waiting less than 3 months. In addition there is concern of a "brain drain" as high quality medical graduates leave Canada for better-paying careers in the U.S.

Taiwan
Taiwan instituted a single payer system, called the National Health Insurance (NHI), in 1995. In a 2009 interview, Dr. Michael Chen, Vice President and CFO of Taiwan's National Health Insurance Bureau explained that before NHI was instituted, Taiwan "sent our people around the world to learn their programs, including the United States" to compare models. Dr. Chen indicated that Taiwan's single-payer NHI program "is modeled after (U.S.) Medicare. And there are so many similarities - other than that our program covers all of the population, and Medicare covers only the elderly.

Medicare in the United States is a single-payer healthcare system, but is restricted to only senior citizens and certain other classes of people.

A number of proposals have been made for a universal single-payer healthcare system in the United States, none of which has achieved significant political support. Proposers include Physicians for a National Health Program , The American College of Physicians and the American Medical Student Association.

In Congress, Rep. John Conyers, Jr. (D-MI), and Rep. Dennis Kucinich (D-OH) have introduced the United States National Health Care Act (HR 676). The bill has been introduced in every term of Congress under the same name since it was first introduced in 2003 in the 108th Congress with 38 cosponsors.

State proposals
In Minnesota, the Minnesota Health Act, which would establish a state-wide single payer health plan, has been presented to the Senate as SF118 and to the House as HF135, in identical language. This bill was passed by several critical committees in both houses, has been designated as a two-year bill, and awaits a second reading in the House Health Care and Human Services Policy & Oversight Committee[21]. Nine out of ten of the 2010 candidates for governor have indicated the would sign the bill, if passed (two of the candidates interviewed that indicated they would not have since left the race)[22].

California's Legislature has twice passed a state-level single payer bill, SB 840, "The California Universal Healthcare Act" (authored by Sheila Kuehl), in 2006 and again in 2008.[23][24][dead link][25][dead link] Both times, Governor Arnold Schwarzenegger vetoed the bill.[26] State Senator Mark Leno later re-introduced "The California Universal Healthcare Act" again in March 2009, newly renumbered as SB 810,[27] and in January of 2010, the California Senate passed SB 810. The bill has received support from the California Nurses Association/National Nurses United and awaits a vote in the state Assembly.[28]

In April 2008, the Illinois House of Representatives' Health Availability Access Committee passed the single-payer bill HB 311, "The Health Care for All Illinois Act," favorably out of committee by an 8-4 vote.

Several single-payer state referendums and bills from state legislatures have been proposed, but so far all have either failed to pass both legislatures or were vetoed by the governor, including (states where the debate is also current) California as early as 1994, Massachusetts in 2000, and Oregon in 2002.[

In February of 2010, the 301-member Pennsylvania Democratic State Committee unanimously endorsed a resolution calling for passage of single payer healthcare, Senate Bill 400 and House Bill 1660, also known as the "Family and Business Healthcare Security Act.

In 2009 the House of Representatives Education and Labor Committee approved an amendment to the House health care bill, which would allow individual states to adopt a single-payer Medicare-for-all-style health plan. The amendment was proposed by Democratic Congress member Dennis Kucinich of Ohio. The Kucinich Amendment received support from some conservatives supporting states rights as it would allow states more freedom to explore various models including, but not limited to, single payer.
