Effective group health plan years beginning after September 23, 2010, if an employer-sponsored health plan allows employees' children to enroll in coverage, then the health plan must allow employees' adult children to enroll as well as long as the adult child is not yet age 26. Some group health insurance plans may also require that the adult child not be eligible for other group health insurance coverage, but only before 2014.[78]
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:
Beginning with 10% of blue-collar workers in 1885, mandatory insurance has expanded; in 2009, insurance was made mandatory on all citizens, with private health insurance for the self-employed or above an income threshold.[23][24] As of 2016, 85% of the population is covered by the compulsory Statutory Health Insurance (SHI)[25] (Gesetzliche Krankenversicherung or GKV), with the remainder covered by private insurance (Private Krankenversicherung or PKV) Germany's health care system was 77% government-funded and 23% privately funded as of 2004.[26] While public health insurance contributions are based on the individual's income, private health insurance contributions are based on the individual's age and health condition.[23][27]
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.
Medicaid was instituted for the very poor in 1965. Since enrollees must pass a means test, Medicaid is a social welfare or social protection program rather than a social insurance program. Despite its establishment, the percentage of US residents who lack any form of health insurance has increased since 1994.[51] It has been reported that the number of physicians accepting Medicaid has decreased in recent years because of lower reimbursement rates.[52]

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.
In 2006, a new system of health insurance came into force in the Netherlands. This new system avoids the two pitfalls of adverse selection and moral hazard associated with traditional forms of health insurance by using a combination of regulation and an insurance equalization pool. Moral hazard is avoided by mandating that insurance companies provide at least one policy which meets a government set minimum standard level of coverage, and all adult residents are obliged by law to purchase this coverage from an insurance company of their choice. All insurance companies receive funds from the equalization pool to help cover the cost of this government-mandated coverage. This pool is run by a regulator which collects salary-based contributions from employers, which make up about 50% of all health care funding, and funding from the government to cover people who cannot afford health care, which makes up an additional 5%.[31]
Healthcare in Switzerland is universal[34] and is regulated by the Swiss Federal Law on Health Insurance. Health insurance is compulsory for all persons residing in Switzerland (within three months of taking up residence or being born in the country).[35][36] It is therefore the same throughout the country and avoids double standards in healthcare. Insurers are required to offer this basic insurance to everyone, regardless of age or medical condition. They are not allowed to make a profit off this basic insurance, but can on supplemental plans.[34]
Employer-sponsored health insurance is paid for by businesses on behalf of their employees as part of an employee benefit package. Most private (non-government) health coverage in the US is employment-based. Nearly all large employers in America offer group health insurance to their employees.[56] The typical large-employer PPO plan is typically more generous than either Medicare or the Federal Employees Health Benefits Program Standard Option.[57]
An alternative proposal is to subsidize private, non-profit health insurance cooperatives to get them to become large and established enough to possibly provide cost savings[27][28] Democratic politicians such as Howard Dean were critical of abandoning a public option in favor of co-ops, raising questions about the ability of the cooperatives to compete with existing private insurers.[6] Paul Krugman also questioned the ability of cooperatives to compete.[29]
Conversely, an IBD/TIPP poll of 1,376 physicians showed that 45% of doctors "would consider leaving or taking early retirement" if Congress passes the health care plan wanted by the White House and Democrats. This poll also found that 65% of physicians oppose the White House and Democratic version of health reform.[55] Statistician and polling expert Nate Silver has criticized that IBD/TIPP poll for what he calls its unusual methodology and bias and for the fact that it was incomplete when published as responses were still coming in.[56]
Insurance plans with higher out-of-pocket costs generally have smaller monthly premiums than plans with low deductibles. When shopping for plans, individuals must weigh the benefits of lower monthly costs against the potential risk of large out-of-pocket expenses in the case of a major illness or accident. Health insurance has many cousins, such as disability insurance, critical (catastrophic) illness insurance, and long-term care (LTC) insurance.
Premiums, or the cost of the medical coverage, are based on some factors including country of origin, age, medical history, etc. It is advised to have more comprehensive insurance for US medical coverage because it can cost a lot, but the costs of not having it can be much higher. For example, the tests and scans doctors often run are costly and typically not covered by budget medical insurance plans.
Nearly one in three patients receiving NHS hospital treatment is privately insured and could have the cost paid for by their insurer. Some private schemes provide cash payments to patients who opt for NHS treatment, to deter use of private facilities. A report, by private health analysts Laing and Buisson, in November 2012, estimated that more than 250,000 operations were performed on patients with private medical insurance each year at a cost of £359 million. In addition, £609 million was spent on emergency medical or surgical treatment. Private medical insurance does not normally cover emergency treatment but subsequent recovery could be paid for if the patient were moved into a private patient unit.[44]
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.
The Affordable Care Act of 2010 was designed primarily to extend health coverage to those without it by expanding Medicaid, creating financial incentives for employers to offer coverage, and requiring those without employer or public coverage to purchase insurance in newly created health insurance exchanges. This requirement for almost all individuals to maintain health insurance is often referred to as the "individual mandate." The CBO has estimated that roughly 33 million who would have otherwise been uninsured will receive coverage because of the act by 2022.[17]
