Health insurance is a form of group insurance, where individuals pay premiums or taxes in order to help protect themselves from high or unexpected healthcare expenses. Health insurance works by estimating the overall "risk" of healthcare expenses and developing a routine finance structure (such as a monthly premium, or annual tax) that will ensure that money is available to pay for the healthcare benefits specified in the insurance agreement. The healthcare benefit is administered by a central organization, which is most often either a government agency, or a private or not-for-profit entity operating a health plan. [1]
Market-based health care systems such as that in the United States rely heavily on private and not-for-profit health insurance.
The concept of health insurance was proposed in 1694 by Hugh the Elder Chamberlen from the Peter Chamberlen family. In the late 19th century, "accident insurance" began to be available, which operated much like modern disability insurance.[2]. This payment model continued until the start of the 20th century in some jurisdictions (like California), where all laws regulating health insurance actually referred to disability insurance.[3] 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.
A Health insurance policy is a contract between an insurance company and an individual. The contract can be renewable annually or monthly. The type and amount of health care costs that will be covered by the health plan are specified in advance, in the member contract or Evidence of Coverage booklet. The individual policy-holder's payment obligations may take several forms[4]:
Prescription drug plans are a form of insurance offered through many employer benefit plans in the U.S., where the patient pays a copayment and the prescription drug insurance pays the rest.
Some health care providers will agree to bill the insurance company if patients are willing to sign an agreement that they will be responsible for the amount that the insurance company doesn't pay, as the insurance company pays according to "reasonable" or "customary" charges, which may be less than the provider's usual fee.
Health insurance companies also often have a network of providers who agree to accept the reasonable and customary fee and waive the remainder. It will generally cost the patient less to use an in-network provider.
Health Insurance companies are now offering Health Incentive accounts (HIA)[5], to reward users for living healthy and making healthy choices, like stop smoking and/or losing weight, may get you funds added into your Health Incentive Account, which may lower your out of pocket costs. The health incentive accounts also carry over from year to year but once you leave the program you lose those benefits in the HIA.
Any private insurance system will face two inherent challenges: adverse selection and ex-post moral hazard.
Insurance companies use the term "adverse selection" to describe the tendency for only those who will benefit from insurance to buy it. Specifically when talking about health insurance, unhealthy people are more likely to purchase health insurance because they anticipate large medical bills. On the other side, people who consider themselves to be reasonably healthy may decide that medical insurance is an unnecessary expense; if they see the doctor once a year and it costs $250, that's much better than making monthly insurance payments of $400 (example figures).
The fundamental concept of insurance is that it balances costs across a large, random sample of individuals (see risk pool). For instance, an insurance company has a pool of 1000 randomly selected subscribers, each paying $100 per month. One person becomes very ill while the others stay healthy, allowing the insurance company to use the money paid by the healthy people to pay for the treatment costs of the sick person. Adverse selection upsets this balance between healthy and sick subscribers by leaving an insurance company with primarily sick subscribers and no way to balance out the cost of their medical expenses with a large number of healthy subscribers.
Because of adverse selection, insurance companies use a patient's medical history to screen out persons with pre-existing medical conditions. Before buying health insurance, a person typically fills out a comprehensive medical history form that asks whether the person smokes, how much the person weighs, whether the person has been treated for any of a long list of diseases and so on. In general, those who present a large financial burdens are denied coverage or charged high premiums to compensate.[5] One large U.S. industry survey found that roughly 13 percent of applicants for comprehensive, individually purchased health insurance that go through the medical underwriting process were denied coverage. Declination rates increased significantly with age, rising from 5 percent for individuals 18 and under to just under a third for individuals aged 60 to 64.[6] On the other side, applicants can get discounts if they do not smoke and are healthy.[7]
Starting in 1976, some states started providing guaranteed-issuance risk pools, which enable individuals who are medically uninsurable through private health insurance to purchase a state-sponsored health insurance plan, usually at higher cost. Minnesota was the first to offer such a plan; 34 states now offer them. Plans vary greatly from state to state, both in their costs and benefits to consumers and to their methods of funding and operations. They serve a very small portion of the uninsurable market — about 182,000 people in the U.S. as of 2004,[8] but in best cases allow people with pre-existing conditions such as cancer, diabetes, heart disease or other chronic illnesses to be able to switch jobs or seek self-employment without fear of being without health care benefits.[9] Efforts to pass a national pool have as yet been unsuccessful, but some federal tax money has been awarded to states to innovate and improve their plans.
Moral hazard describes the state of mind and change in behavior that results from a person's knowledge that if something bad were to happen, the out-of-pocket expenses would be mitigated by an insurance policy--in this case, one which provides reduced prices for medical care.
A recent study by PriceWaterhouseCoopers examining the drivers of rising health care costs in the U.S. pointed to increased utilization created by increased consumer demand, new treatments, and more intensive diagnostic testing, as the most significant driver.[10] People in developed countries are living longer. The population of those countries is aging, and a larger group of senior citizens requires more medical care than a young healthier population. Advances in medicine and medical technology can also increase the cost of medical treatment. Other factors that increase utilization and therefore insurance prices are lifestyle-related: increases in obesity caused by insufficient exercise and unhealthy food choices; excessive alcohol use, smoking, and use of street drugs. Other factors noted by the PWC study included the movement to broader-access plans, higher-priced technologies, and cost-shifting from Medicaid and the uninsured to private payers.[10]
Template:Tfd Some common complaints about private health insurance include:
According to the United States Census Bureau, approximately 84% of Americans have health insurance. Some 60% obtain health insurance through an employer, about 9% purchase it directly, and various government agencies provide coverage to about 27% of Americans (there is some overlap in these figures).[12] In 2006, there were 47 million people in the U.S. (16 percent of the population) who were without health insurance for at least part of that year.[12] About 37% of the uninsured live in households with an income over $50,000.Closing </ref> missing for <ref> tag
Health insurance paid for by business entities generally on behalf of their employees and other immediate stakeholders. Broadly classified as "Traditional/Indemnity" and "Managed/Preferred Provider." Most private health coverage in the U.S. is employment based, and the employer typically makes a substantial contribution towards the cost of coverage.[13]
Costs for employer-paid health insurance are rising rapidly: since 2001, premiums for family coverage have increased 78%, while wages have risen 19% and inflation has risen 17%, according to a 2007 study by the Kaiser Family Foundation.[14]
According the Centers for Medicare and Medicaid Services, nearly 100% of large firms offer health insurance to their employees.[15] Although much more likely to offer retiree health benefits than small firms, the percentage of large firms offering these benefits fell from 66% in 1988 to 34% in 2002.[16]
Many small employers provide employee health insurance, but the percentage offering is not as high as it is for larger employers. The types of coverage available to small employers are similar, but they do not have the same options for financing their benefit plans. In particular, self-insuring the benefits (see Self-funded health care) is not a practical option for most small employers. [17]
Policies of health insurance obtained by individuals not otherwise covered under policies or programs elsewhere classified. Generally major medical, short term medical, and student policies. Fewer Americans are covered by individually purchased medical expense insurance than by employer-sponsored coverage. The range of products available is similar, however. Average premiums are generally somewhat lower than those for employer-sponsored coverage, but vary by age. Deductibles and other cost-sharing is also higher, on average, and the individual consumer pays the entire premium without benefit of an employer contribution.[18][6] Many states allow medical underwriting of applicants for individually purchased health insurance by insurance companies.
Long-term care (LTC) insurance is growing in popularity in the U.S. Premiums have remained relatively stable in recent years. However, the coverage is quite expensive, especially when consumers wait until retirement age to purchase it. The average age of new purchasers was 61 in 2005, and has been dropping.[19]
Through the 1990s, managed care grew from about 25% of U.S. employees to the vast majority.

One approach to addressing increasing premiums, dubbed "consumer driven health care," 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). An HSA is a private bank account which is un-taxed and only penalized if spent on non-medical items or services. It must be paired with a high-deductible insurance plan. HSAs enable mostly healthy people to pay less for insurance and bank money for their own health care expenses.[20] HSAs are one form of tax-preferrenced health care spending account. Others include Archer Medical Savings Accounts (MSAs), which have been superseded by the new HSAs (although existing MSAs are grandfathered), Flexible Spending Arrangments (FSAs) and Health Reimbursement Accounts (HRAs). FSAs and HRAs are typically used as part of an employee-benefit plan.[21]
Limited Medical Benefit Plans pay for routine care and do not pay for catastrophic care. As such, they do not provide equivalent financial security to a major medical plan. Annual benefit limits can be as low as $2,000. Lifetime maximums can be very low as well.
Most health insurance in Canada is administered by each province, under the national law that requires all people to have free access to basic health services. Collectively, the public provincial health insurance systems in Canada are called Medicare. Private health insurance in Canada is allowed only for services that the public health plans do not cover; for example, semi-private or private rooms in hospitals and prescription drug plans. Canadians also must use private insurance for elective medical services such as Lasik surgery, plastic surgery such as liposuction, and other non-basic medical procedures. Private health care cannot cover physician fees which are covered by Medicare. Private-sector services not paid for by the government accounted for nearly 30 percent of total health care spending.[24]. In 2005, the Supreme Court of Quebec ruled, in Chaoulli v. Quebec, that the prohibition on insurance for health care already insured by the state constitutes an infringement of the right to life and security. It is yet to be seen if this ruling will change the overall delivery of health insurance across Canada.
The public health system is called Medicare. It ensures free universal access to hospital treatment and subsidised out-of-hospital medical treatment. It is funded by a 1.5% tax levy.
The private health system is funded by a number of private health insurance organisations. The largest of these is Medibank Private, which is government-owned, but operates as a government business enterprise under the same regulatory regime as all other registered private health funds; the Howard government has announced that Medibank will be privatised in 2008 assuming it is returned to office at the 2007 election. Some private health insurers are 'for profit' enterprises, and some are non-profit organizations.
Most aspects of private health insurance in Australia are regulated by the Private Health Insurance Act 2007.
The private health system in Australia operates on a "community rating" system, whereby premiums do not vary solely because of a person's previous medical history or current state of health. Balancing this are waiting periods, in particular for pre-existing conditions. Funds are entitled to impose a waiting period of up to 12 months on benefits for any medical condition the signs and symptoms of which existed during the six months ending on the day the person first took out insurance.
The Australian government has introduced a number of incentives to encourage adults to take out private hospital insurance. These include:
