The UK's National Health Service (NHS) is a publicly funded healthcare system that provides coverage to everyone normally resident in the UK. It is not strictly an insurance system because (a) there are no premiums collected, (b) costs are not charged at the patient level and (c) costs are not pre-paid from a pool. However, it does achieve the main aim of insurance which is to spread financial risk arising from ill-health. The costs of running the NHS (est. £104 billion in 2007-8)[39] are met directly from general taxation. The NHS provides the majority of health care in the UK, including primary care, in-patient care, long-term health care, ophthalmology, and dentistry.
Finally achieving universal health coverage remained a top priority among Democrats, and passing a health reform bill was one of the Obama Administration's top priorities. The Patient Protection and Affordable Care Act was similar to the Nixon and Clinton plans, mandating coverage, penalizing employers who failed to provide it, and creating mechanisms for people to pool risk and buy insurance collectively.[9] Earlier versions of the bill included a publicly run insurer that could compete to cover those without employer sponsored coverage (the so-called public option), but this was ultimately stripped to secure the support of moderates. The bill passed the Senate in December 2009 with all Democrats voting in favor and the House in March 2010 with the support of most Democrats. Not a single Republican voted in favor of it either time.

As Germany has the world's oldest SHI [social health insurance] system, it naturally lends itself to historical analyses.

Employer-sponsored health insurance plans dramatically expanded as a direct result of wage controls imposed by the federal government during World War II.[20] The labor market was tight because of the increased demand for goods and decreased supply of workers during the war. Federally imposed wage and price controls prohibited manufacturers and other employers from raising wages enough to attract workers. When the War Labor Board declared that fringe benefits, such as sick leave and health insurance, did not count as wages for the purpose of wage controls, employers responded with significantly increased offers of fringe benefits, especially health care coverage, to attract workers.[20]
Health benefits are provided to active duty service members, retired service members and their dependents by the Department of Defense Military Health System (MHS). The MHS consists of a direct care network of Military Treatment Facilities and a purchased care network known as TRICARE. Additionally, veterans may also be eligible for benefits through the Veterans Health Administration.
While politically difficult, some politicians and observers have argued for a single-payer system.[30] A bill, the United States National Health Care Act, was first proposed by Representative John Conyers in 2003[31] and has been perennially proposed since, including during the debate on the public option and the Patient Protection and Affordable Care Act.[32] President Obama has come out against a single-payer reform at this time, stating in the joint session of Congress that "it makes more sense to build on what works and fix what doesn't, rather than try to build an entirely new system from scratch."[33] Obama had previously expressed that he is a proponent of a single payer universal health care program during an AFL-CIO conference in 2003.[34]

Germans are offered three kinds of social security insurance dealing with the physical status of a person and which are co-financed by employer and employee: health insurance, accident insurance, and long-term care insurance. Long-term care insurance (Gesetzliche Pflegeversicherung) emerged in 1994 and is mandatory.[24] Accident insurance (gesetzliche Unfallversicherung) is covered by the employer and basically covers all risks for commuting to work and at the workplace.[citation needed]
Historically, health insurance has been regulated by the states, consistent with the McCarran-Ferguson Act. Details for what health insurance could be sold were up to the states, with a variety of laws and regulations. Model acts and regulations promulgated by the National Association of Insurance Commissioners (NAIC) provide some degree of uniformity state to state. These models do not have the force of law and have no effect unless they are adopted by a state. They are, however, used as guides by most states, and some states adopt them with little or no change.
Health insurance companies are not actually providing traditional insurance, which involves the pooling of risk, because the vast majority of purchasers actually do face the harms that they are "insuring" against. Instead, as Edward Beiser and Jacob Appel have separately argued, health insurers are better thought of as low-risk money managers who pocket the interest on what are really long-term healthcare savings accounts.[131][132]
A 2011 study found that there were 2.1 million hospital stays for uninsured patients, accounting for 4.4% ($17.1 billion) of total aggregate inpatient hospital costs in the United States.[12] The costs of treating the uninsured must often be absorbed by providers as charity care, passed on to the insured via cost-shifting and higher health insurance premiums, or paid by taxpayers through higher taxes.[13]
