Hospital indemnity insurance provides a fixed daily, weekly or monthly benefit while the insured is confined in a hospital. The payment is not dependent on actual hospital charges, and is most commonly expressed as a flat dollar amount. Hospital indemnity benefits are paid in addition to any other benefits that may be available, and are typically used to pay out-of-pocket and non-covered expenses associated with the primary medical plan, and to help with additional expenses (e.g., child care) incurred while in the hospital.[19][95]
Private health care has continued parallel to the NHS, paid for largely by private insurance, but it is used by less than 8% of the population, and generally as a top-up to NHS services. There are many treatments that the private sector does not provide. For example, health insurance on pregnancy is generally not covered or covered with restricting clauses. Typical exclusions for Bupa schemes (and many other insurers) include:

In 2003, according to the Heartland Institute's Merrill Matthews, association group health insurance plans offered affordable health insurance to "some 6 million Americans." Matthews responded to the criticism that said that some associations work too closely with their insurance providers. He said, "You would expect the head of AARP to have a good working relationship with the CEO of Prudential, which sells policies to AARP's seniors."[83]
In 1935 the decision was made by the Roosevelt Administration not to include a large-scale health insurance program as part of the new Social Security program. The problem was not an attack by any organized opposition, such as the opposition from the American Medical Association that derailed Truman's proposals in 1949. Instead, there was a lack of active popular, congressional, or interest group support. Roosevelt's strategy was to wait for a demand and a program to materialize, and then if he thought it popular enough to throw his support behind it. His Committee on Economic Security (CES) deliberately limited the health segment of Social Security to the expansion of medical care and facilities. It considered unemployment insurance to be the major priority. Roosevelt assured the medical community that medicine would be kept out of politics. Jaap Kooijman says he succeeded in "pacifying the opponents without discouraging the reformers." The right moment never came for him to reintroduce the topic.[23][24]
Health insurance primarily protects individuals from the prohibitively high costs of surgical procedures, inpatient hospital care, and emergency attention. Though health insurance itself can become costly for a family, it is only a small fraction of the potential costs associated with unforeseen illnesses and emergencies (for example, the diagnosis and treatment of cancer or a heart attack).

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.
Coupled with high-deductible plans are various tax-advantaged savings plans—funds (such as salary) can be placed in a savings plan, and then go to pay the out-of-pocket expenses. This approach to addressing increasing premiums is dubbed "consumer driven health care", and received a boost in 2003, when President George W. Bush signed into law the Medicare Prescription Drug, Improvement, and Modernization Act. The law created tax-deductible Health Savings Accounts (HSAs), untaxed private bank accounts for medical expenses, which can be established by those who already have health insurance. Withdrawals from HSAs are only penalized if the money is spent on non-medical items or services. Funds can be used to pay for qualified expenses, including doctor's fees, Medicare Parts A and B, and drugs, without being taxed.[106]

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.[65] The predecessors of today's Health Maintenance Organizations (HMOs) originated beginning in 1929, through the 1930s and on during World War II.[67][68]

Approximately 19 percent of Americans had coverage under Medicaid in 2016, and 14 percent had coverage under Medicare. These are government-run programs, as opposed to private coverage. However, the state and federal governments contract with private insurers to offer Medicaid managed care plans and Medicare Advantage plans, all of which are run by private insurers (in many cases, the same private insurers that offer employer-sponsored and individual market plans to the rest of the population).
Dental insurance helps pay for the cost of necessary dental care. Few medical expense plans include coverage for dental expenses. About 97% of dental benefits in the United States is provided through separate policies from carriers—both stand-alone and medical affiliates—that specialize in this coverage. Typically, these dental plans offer comprehensive preventive benefits. However, major dental expenses, such as crowns and root canals, are just partially covered. Also, most carriers offer a lower rate if you select a plan that utilizes their Network providers. Discount dental programs are also available. These do not constitute insurance, but provide participants with access to discounted fees for dental work.

As far as the compulsory health insurance is concerned, the insurance companies cannot set any conditions relating to age, sex or state of health for coverage. Although the level of premium can vary from one company to another, they must be identical within the same company for all insured persons of the same age group and region, regardless of sex or state of health. This does not apply to complementary insurance, where premiums are risk-based.
Americans are required to carry medical insurance that meets federally designated minimum standards or face a tax penalty. In certain cases, taxpayers may qualify for an exemption from the penalty if they were unable to obtain insurance due to financial hardship or other situations. Two public health insurance plans, Medicare and the Children's Health Insurance Program, target older individuals and children, respectively. Medicare also serves people with certain disabilities. The program is available to anyone age 65 or older. The CHIP plan has income limits and covers babies and children up to the age of 18.
President Harry S. Truman proposed a system of public health insurance in his November 19, 1945, address. He envisioned a national system that would be open to all Americans, but would remain optional. Participants would pay monthly fees into the plan, which would cover the cost of any and all medical expenses that arose in a time of need. The government would pay for the cost of services rendered by any doctor who chose to join the program. In addition, the insurance plan would give cash to the policy holder to replace wages lost because of illness or injury. The proposal was quite popular with the public, but it was fiercely opposed by the Chamber of Commerce, the American Hospital Association, and the AMA, which denounced it as "socialism".[25]

Out-of-pocket maximum: Similar to coverage limits, except that in this case, the insured person's payment obligation ends when they reach the out-of-pocket maximum, and health insurance pays all further covered costs. Out-of-pocket maximum can be limited to a specific benefit category (such as prescription drugs) or can apply to all coverage provided during a specific benefit year.
However, in a 2007 analysis, the Employee Benefit Research Institute concluded that the availability of employment-based health benefits for active workers in the US is stable. The "take-up rate," or percentage of eligible workers participating in employer-sponsored plans, has fallen somewhat, but not sharply. EBRI interviewed employers for the study, and found that others might follow if a major employer discontinued health benefits. Effective by January 1, 2014, the Patient Protection and Affordable Care Act will impose a $2000 per employee tax penalty on employers with over 50 employees who do not offer health insurance to their full-time workers. (In 2008, over 95% of employers with at least 50 employees offered health insurance.[63])[64] On the other hand, public policy changes could also result in a reduction in employer support for employment-based health benefits.[65]

Health insurance in the United States is any program that helps pay for medical expenses, whether through privately purchased insurance, social insurance, or a social welfare program funded by the government.[1] Synonyms for this usage include "health coverage", "health care coverage", and "health benefits". In a more technical sense, the term "health insurance" is used to describe any form of insurance providing protection against the costs of medical services. This usage includes private insurance and social insurance programs such as Medicare, which pools resources and spreads the financial risk associated with major medical expenses across the entire population to protect everyone, as well as social welfare programs like Medicaid and the Children's Health Insurance Program, which both provide assistance to people who cannot afford health coverage.
