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 benefit is administered by a central organization, most often either a government agency or a private or not-for-profit entity operating a health plan.

How it works
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[7]:

Premium: The amount the policy-holder pays to the health plan each month to purchase health coverage.
Deductible: The amount that the policy-holder must pay out-of-pocket before the health plan pays its share. For example, a policy-holder might have to pay a $500 deductible per year, before any of their health care is covered by the health plan. It may take several doctor's visits or prescription refills before the policy-holder reaches the deductible and the health plan starts to pay for care.
Copayment: The amount that the policy-holder must pay out of pocket before the health plan pays for a particular visit or service. For example, a policy-holder might pay a $45 copayment for a doctor's visit, or to obtain a prescription. A copayment must be paid each time a particular service is obtained.
Coinsurance: Instead of paying a fixed amount up front (a copayment), the policy-holder must pay a percentage of the total cost. For example, the member might have to pay 20% of the cost of a surgery, while the health plan pays the other 80%. Because there is no upper limit on coinsurance, the policy-holder can end up owing very little, or a significant amount, depending on the actual costs of the services they obtain.
Exclusions: Not all services are covered. The policy-holder is generally expected to pay the full cost of non-covered services out of their own pocket.
Coverage limits: Some health plans only pay for health care up to a certain dollar amount. The policy-holder may be expected to pay any charges in excess of the health plan's maximum payment for a specific service. In addition, some plans have annual or lifetime coverage maximums. In these cases, the health plan will stop payment when they reach the benefit maximum, and the policy-holder must pay all remaining costs.
Out-of-pocket maximums: Similar to coverage limits, except that in this case, the member's payment obligation ends when they reach the out-of-pocket maximum, and the health plan pays all further covered costs. Out-of-pocket maximums can be limited to a specific benefit category (such as prescription drugs) or can apply to all coverage provided during a specific benefit year.
Capitation: An amount paid by an insurer to a health care provider, for which the provider agrees to treat all members of the insurer.
In-Network Provider: A health care provider on a list of providers preselected by the insurer. The insurer will offer discounted coinsurance or copayments, or additional benefits, to a plan member to see an in-network provider. Generally, providers in network are providers who have a contract with the insurer to accept rates further discounted from the "usual and customary" charges the insurer pays to out-of-network providers.
Prescription drug plans are a form of insurance offered through some employer benefit plans in the US, where the patient pays a copayment and the prescription drug insurance part or all of the balance for drugs covered in the formulary of the plan.

Some, if not most, health care providers in the United States 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. The insurance company pays out of network providers according to "reasonable and customary" charges, which may be less than the provider's usual fee. The provider may also have a separate contract with the insurer to accept what amounts to a discounted rate or capitation to the provider's standard charges. It generally costs the patient less to use an in-network provider.

Health plan vs. health insurance
Historically, HMOs tended to use the term "health plan", while commercial insurance companies used the term "health insurance". A health plan can also refer to a subscription-based medical care arrangement offered through health maintenance organization, HMO, PPO, or POS plan. These plans are similar to pre-paid dental, pre-paid legal, and pre-paid vision plans. Pre-paid health plans typically pay for a fixed number of services (for instance, $300 in preventive care, a certain number of days of hospice care or care in a skilled nursing facility, a fixed number of home health visits, a fixed number of spinal manipulation charges, etc.) The services offered are usually at the discretion of a utilization review nurse who is often contracted through the managed care entity providing the subscription health plan. This determination may be made either prior to or after hospital admission (concurrent utilization review).

[edit] Inherent problems with insurance
Insurance systems must typically deal with two inherent challenges: adverse selection, which affects any voluntary system, and ex-post moral hazard, which affects any insurance system in which a third party bears major responsibility for payment, whether that is an employer or the government. Some national systems with compulsory insurance utilize systems such as risk equalization and community rating to overcome these inherent problems.

[edit] Adverse selection
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 $40. (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. However, when the pool is self-selecting rather than random, as is the case with individuals seeking to purchase health insurance directly, adverse selection is a greater concern.[8] A disproportionate share of health care spending is attributable to individuals with high health care costs. In the US the 1% of the population with the highest spending accounted for 27% of aggregate health care spending in 1996. The highest-spending 5% of the population accounted for more than half of all spending. These patterns were stable through the 1970s and 1980s, and some data suggest that they may have been typical of the mid-to-early 20th century as well.[9][10] A few individuals have extremely high medical expenses, in extreme cases totaling a half million dollars or more.[11] Adverse selection could leave 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 employ medical underwriting, using a patient's medical history to screen out those whose pre-existing medical conditions pose too great a risk for the risk pool. 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 large financial burdens are denied coverage or charged high premiums to compensate.[12] One large US industry survey found that roughly 13 percent of applicants for comprehensive, individually purchased health insurance who went through the medical underwriting in 2004 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.[13] Among those who were offered coverage, the study found that 76% received offers at standard premium rates, and 22% were offered higher rates.[14] On the other side, applicants can get discounts if they do not smoke and are healthy.[15]

Health insurance in Canada
Most health insurance in Canada is administered by each province, under the Canada Health Act, which requires all people to have free access to basic health services. Collectively, the public provincial health insurance systems in Canada are frequently referred to as Medicare. Private health insurance is allowed, but the provincial governments allow it 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 are free to use private insurance for elective medical services such as laser vision correction surgery, cosmetic surgery, and other non-basic medical procedures. Some 65% of Canadians have some form of supplementary private health insurance; many of them receive it through their employers.[17] Private-sector services not paid for by the government account for nearly 30 percent of total health care spending.[18]

In 2005, the Supreme Court of Quebec ruled, in Chaoulli v. Quebec, that the province's prohibition on private insurance for health care already insured by the provincial plan could constitute an infringement of the right to life and security if there were long wait times for treatment as happened in this case. Certain other provinces have legislation which financially discourages but does not forbid private health insurance in areas covered by the public plans. The ruling has not changed the overall pattern of health insurance across Canada but has spurred on attempts to tackle the core issues of supply and demand and the impact of wait times.[19]

Health insurance in the Netherlands
In the Netherlands in 2006, a new system of health insurance came into force. All insurance companies have to provide at least one policy which meets a government set minimum standard level of cover and all adult residents are obliged by law to purchase this cover from an insurance company of their choice.

The new system avoids the two pitfalls of adverse selection and moral hazard associated with traditional forms of health insurance.

In the Dutch system, insurance companies are compensated for taking on high risk individuals because they receive extra funding for them. This funding comes from an insurance equalization pool run by a regulator which collects salary based contributions from employers (about 45% of all health care funding) and funding from the government for people whose means are such that they cannot afford health care (about 5% of all funding). Thus insurance companies find that insuring high risk individuals becomes an attractive proposition. All insurance companies receive from the pool, but those with more high risk individuals will receive more from the fund. The remaining 45% of health care funding comes from insurance premiums paid by the public. Insurance companies compete for this money on price alone. The insurance companies are not allowed to set down any co-payments or caps or deductibles. Neither are they allowed to deny coverage to any person applying for a policy or charge anything other than their nationally set and internet published standard policy premiums. Every person buying insurance from that company will pay the same price as everyone else buying that policy. And every person will get the minimum level of coverage. Children under 18 are insured for free (the funding coming from the equalization pool).

In addition to this minimum level, companies are free to sell extra insurance for additional coverage over the national minimum, but extra risks for this are not covered from the insurance pool and must therefore be priced accordingly.

Health insurance in the United Kingdom
Main article: National Health Service
Great Britain's National Health Service (NHS) is a publicly funded healthcare system that provides coverage to everyone normally resident in the UK. The NHS provides the majority of health care in England, including primary care, in-patient care, long-term health care, ophthalmology and dentistry. 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. Recently the private sector has been increasingly used to increase NHS capacity despite a large proportion of the British public opposing such involvement.[20]. According to the World Health Organization, government funding covered 86% of overall health care expenditures in the UK as of 2004, with private expenditures covering the remaining 14%.[21] The costs of running the NHS (est. £104 billion in 2007-8)[22] are met directly from general taxation.

The National Health Service Act 1946 came into effect on 5 July 1948. The UK government department responsible for the NHS is the Department of Health, headed by a Secretary of State for Health (Health Secretary), who sits in the British Cabinet. The NHS is the world's largest health service, and the world's third largest employer[23] after the Chinese army and the Indian railways.

Insurance, in law and economics, is a form of risk management primarily used to hedge against the risk of a contingent loss. Insurance is defined as the equitable transfer of the risk of a loss, from one entity to another, in exchange for a premium. An insurer is a company selling the insurance. The insurance rate is a factor used to determine the amount, called the premium, to be charged for a certain amount of insurance coverage. Risk management, the practice of appraising and controlling risk, has evolved as a discrete field of study and practice.

Principles of insurance
A large number of homogeneous exposure units. The vast majority of insurance policies are provided for individual members of very large classes. Automobile insurance, for example, covered about 175 million automobiles in the United States in 2004.[2] The existence of a large number of homogeneous exposure units allows insurers to benefit from the so-called “law of large numbers,” which in effect states that as the number of exposure units increases, the actual results are increasingly likely to become close to expected results. There are exceptions to this criterion. Lloyd's of London is famous for insuring the life or health of actors, actresses and sports figures. Satellite Launch insurance covers events that are infrequent. Large commercial property policies may insure exceptional properties for which there are no ‘homogeneous’ exposure units. Despite failing on this criterion, many exposures like these are generally considered to be insurable.
Definite Loss. The event that gives rise to the loss that is subject to insurance should, at least in principle, take place at a known time, in a known place, and from a known cause. The classic example is death of an insured on a life insurance policy. Fire, automobile accidents, and worker injuries may all easily meet this criterion. Other types of losses may only be definite in theory. Occupational disease, for instance, may involve prolonged exposure to injurious conditions where no specific time, place or cause is identifiable. Ideally, the time, place and cause of a loss should be clear enough that a reasonable person, with sufficient information, could objectively verify all three elements.
Accidental Loss. The event that constitutes the trigger of a claim should be fortuitous, or at least outside the control of the beneficiary of the insurance. The loss should be ‘pure,’ in the sense that it results from an event for which there is only the opportunity for cost. Events that contain speculative elements, such as ordinary business risks, are generally not considered insurable.
Large Loss. The size of the loss must be meaningful from the perspective of the insured. Insurance premiums need to cover both the expected cost of losses, plus the cost of issuing and administering the policy, adjusting losses, and supplying the capital needed to reasonably assure that the insurer will be able to pay claims. For small losses these latter costs may be several times the size of the expected cost of losses. There is little point in paying such costs unless the protection offered has real value to a buyer.
Affordable Premium. If the likelihood of an insured event is so high, or the cost of the event so large, that the resulting premium is large relative to the amount of protection offered, it is not likely that anyone will buy insurance, even if on offer. Further, as the accounting profession formally recognizes in financial accounting standards, the premium cannot be so large that there is not a reasonable chance of a significant loss to the insurer. If there is no such chance of loss, the transaction may have the form of insurance, but not the substance. (See the U.S. Financial Accounting Standards Board standard number 113)
Calculable Loss. There are two elements that must be at least estimable, if not formally calculable: the probability of loss, and the attendant cost. Probability of loss is generally an empirical exercise, while cost has more to do with the ability of a reasonable person in possession of a copy of the insurance policy and a proof of loss associated with a claim presented under that policy to make a reasonably definite and objective evaluation of the amount of the loss recoverable as a result of the claim.
Limited risk of catastrophically large losses. The essential risk is often aggregation. If the same event can cause losses to numerous policyholders of the same insurer, the ability of that insurer to issue policies becomes constrained, not by factors surrounding the individual characteristics of a given policyholder, but by the factors surrounding the sum of all policyholders so exposed. Typically, insurers prefer to limit their exposure to a loss from a single event to some small portion of their capital base, on the order of 5 percent. Where the loss can be aggregated, or an individual policy could produce exceptionally large claims, the capital constraint will restrict an insurers appetite for additional policyholders. The classic example is earthquake insurance, where the ability of an underwriter to issue a new policy depends on the number and size of the policies that it has already underwritten. Wind insurance in hurricane zones, particularly along coast lines, is another example of this phenomenon. In extreme cases, the aggregation can affect the entire industry, since the combined capital of insurers and reinsurers can be small compared to the needs of potential policyholders in areas exposed to aggregation risk. In commercial fire insurance it is possible to find single properties whose total exposed value is well in excess of any individual insurer’s capital constraint. Such properties are generally shared among several insurers, or are insured by a single insurer who syndicates the risk into the reinsurance market.

[edit] Indemnification
Main article: Indemnity
The technical definition of "indemnity" means to make whole again. There are two types of insurance contracts; 1) an "indemnity" policy and 2) a "pay on behalf" or "on behalf of"[3] policy. The difference is significant on paper, but rarely material in practice.

An "indemnity" policy will never pay claims until the insured has paid out of pocket to some third party; i.e. a visitor to your home slips on a floor that you left wet and sues you for $10,000 and wins. Under an "indemnity" policy the homeowner would have to come up with the $10,000 to pay for the visitors fall and then would be "indemnified" by the insurance carrier for the out of pocket costs (the $10,000)[4].

Under the same situation, a "pay on behalf" policy, the insurance carrier would pay the claim and the insured (the homeowner) would not be out of pocket for anything. Most modern liability insurance is written on the basis of "pay on behalf" language[5].

An entity seeking to transfer risk (an individual, corporation, or association of any type, etc.) becomes the 'insured' party once risk is assumed by an 'insurer', the insuring party, by means of a contract, called an insurance 'policy'. Generally, an insurance contract includes, at a minimum, the following elements: the parties (the insurer, the insured, the beneficiaries), the premium, the period of coverage, the particular loss event covered, the amount of coverage (i.e., the amount to be paid to the insured or beneficiary in the event of a loss), and exclusions (events not covered). An insured is thus said to be "indemnified" against the loss events covered in the policy.

When insured parties experience a loss for a specified peril, the coverage entitles the policyholder to make a 'claim' against the insurer for the covered amount of loss as specified by the policy. The fee paid by the insured to the insurer for assuming the risk is called the 'premium'. Insurance premiums from many insureds are used to fund accounts reserved for later payment of claims—in theory for a relatively few claimants—and for overhead costs. So long as an insurer maintains adequate funds set aside for anticipated losses (i.e., reserves), the remaining margin is an insurer's profit.

[edit] Insurer’s business model
Profit = earned premium + investment income - incurred loss - underwriting expenses.

Insurers make money in two ways: (1) through underwriting, the process by which insurers select the risks to insure and decide how much in premiums to charge for accepting those risks and (2) by investing the premiums they collect from insureds.

The most difficult aspect of the insurance business is the underwriting of policies. Using a wide assortment of data, insurers predict the likelihood that a claim will be made against their policies and price products accordingly. To this end, insurers use actuarial science to quantify the risks they are willing to assume and the premium they will charge to assume them. Data is analyzed to fairly accurately project the rate of future claims based on a given risk. Actuarial science uses statistics and probability to analyze the risks associated with the range of perils covered, and these scientific principles are used to determine an insurer's overall exposure. Upon termination of a given policy, the amount of premium collected and the investment gains thereon minus the amount paid out in claims is the insurer's underwriting profit on that policy. Of course, from the insurer's perspective, some policies are winners (i.e., the insurer pays out less in claims and expenses than it receives in premiums and investment income) and some are losers (i.e., the insurer pays out more in claims and expenses than it receives in premiums and investment income).

An insurer's underwriting performance is measured in its combined ratio. The loss ratio (incurred losses and loss-adjustment expenses divided by net earned premium) is added to the expense ratio (underwriting expenses divided by net premium written) to determine the company's combined ratio. The combined ratio is a reflection of the company's overall underwriting profitability. A combined ratio of less than 100 percent indicates underwriting profitability, while anything over 100 indicates an underwriting loss.

Insurance companies also earn investment profits on “float”. “Float” or available reserve is the amount of money, at hand at any given moment, that an insurer has collected in insurance premiums but has not been paid out in claims. Insurers start investing insurance premiums as soon as they are collected and continue to earn interest on them until claims are paid out.

In the United States, the underwriting loss of property and casualty insurance companies was $142.3 billion in the five years ending 2003. But overall profit for the same period was $68.4 billion, as the result of float. Some insurance industry insiders, most notably Hank Greenberg, do not believe that it is forever possible to sustain a profit from float without an underwriting profit as well, but this opinion is not universally held. Naturally, the “float” method is difficult to carry out in an economically depressed period. Bear markets do cause insurers to shift away from investments and to toughen up their underwriting standards. So a poor economy generally means high insurance premiums. This tendency to swing between profitable and unprofitable periods over time is commonly known as the "underwriting" or insurance cycle. [6]

Property and casualty insurers currently make the most money from their auto insurance line of business. Generally better statistics are available on auto losses and underwriting on this line of business has benefited greatly from advances in computing. Additionally, property losses in the US, due to natural catastrophes, have exacerbated this trend.

Finally, claims and loss handling is the materialized utility of insurance. In managing the claims-handling function, insurers seek to balance the elements of customer satisfaction, administrative handling expenses, and claims overpayment leakages. As part of this balancing act, fraudulent insurance practices are a major business risk that must be managed and overcome.

Types of insurance
Any risk that can be quantified can potentially be insured. Specific kinds of risk that may give rise to claims are known as "perils". An insurance policy will set out in detail which perils are covered by the policy and which are not. Below are (non-exhaustive) lists of the many different types of insurance that exist. A single policy may cover risks in one or more of the categories set forth below. For example, auto insurance would typically cover both property risk (covering the risk of theft or damage to the car) and liability risk (covering legal claims from causing an accident). A homeowner's insurance policy in the U.S. typically includes property insurance covering damage to the home and the owner's belongings, liability insurance covering certain legal claims against the owner, and even a small amount of health insurance for medical expenses of guests who are injured on the owner's property.

Business insurance can be any kind of insurance that protects businesses against risks. Some principal subtypes of business insurance are (a) the various kinds of professional liability insurance, also called professional indemnity insurance, which are discussed below under that name; and (b) the business owners policy (BOP), which bundles into one policy many of the kinds of coverage that a business owner needs, in a way analogous to how homeowners insurance bundles the coverages that a homeowner needs.[7]

Health
Health insurance policies will often cover the cost of private medical treatments if the National Health Service in the United Kingdom (NHS) or other publicly-funded health programs do not pay for them. It will often result in quicker health care where better facilities are available. Dental insurance, like medical insurance, is coverage for individuals to protect them against dental costs. In the U.S., dental insurance is often part of an employer's benefits package, along with health insurance. Most countries rely on public funding to ensure that all citizens have universal access to health care.

[edit] Disability
Disability insurance policies provide financial support in the event the policyholder is unable to work because of disabling illness or injury. It provides monthly support to help pay such obligations as mortgages and credit cards.
Total permanent disability insurance insurance provides benefits when a person is permanently disabled and can no longer work in their profession, often taken as an adjunct to life insurance.
Disability overhead insurance allows business owners to cover the overhead expenses of their business while they are unable to work.
Workers' compensation insurance replaces all or part of a worker's wages lost and accompanying medical expense incurred because of a job-related injury.

Casualty
Casualty insurance insures against accidents, not necessarily tied to any specific property.

Crime insurance is a form of casualty insurance that covers the policyholder against losses arising from the criminal acts of third parties. For example, a company can obtain crime insurance to cover losses arising from theft or embezzlement.
Political risk insurance is a form of casualty insurance that can be taken out by businesses with operations in countries in which there is a risk that revolution or other political conditions will result in a loss.

[edit] Life insurance
Main article: Life insurance
Life insurance provides a monetary benefit to a decedent's family or other designated beneficiary, and may specifically provide for income to an insured person's family, burial, funeral and other final expenses. Life insurance policies often allow the option of having the proceeds paid to the beneficiary either in a lump sum cash payment or an annuity.

Annuities provide a stream of payments and are generally classified as insurance because they are issued by insurance companies and regulated as insurance and require the same kinds of actuarial and investment management expertise that life insurance requires. Annuities and pensions that pay a benefit for life are sometimes regarded as insurance against the possibility that a retiree will outlive his or her financial resources. In that sense, they are the complement of life insurance and, from an underwriting perspective, are the mirror image of life insurance.

Certain life insurance contracts accumulate cash values, which may be taken by the insured if the policy is surrendered or which may be borrowed against. Some policies, such as annuities and endowment policies, are financial instruments to accumulate or liquidate wealth when it is needed.

In many countries, such as the U.S. and the UK, the tax law provides that the interest on this cash value is not taxable under certain circumstances. This leads to widespread use of life insurance as a tax-efficient method of saving as well as protection in the event of early death.

In U.S., the tax on interest income on life insurance policies and annuities is generally deferred. However, in some cases the benefit derived from tax deferral may be offset by a low return. This depends upon the insuring company, the type of policy and other variables (mortality, market return, etc.). Moreover, other income tax saving vehicles (e.g., IRAs, 401(k) plans, Roth IRAs) may be better alternatives for value accumulation. A combination of low-cost term life insurance and a higher-return tax-efficient retirement account may achieve better investment return.

Property
Property insurance provides protection against risks to property, such as fire, theft or weather damage. This includes specialized forms of insurance such as fire insurance, flood insurance, earthquake insurance, home insurance, inland marine insurance or boiler insurance.

Health insurance
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 benefit is administered by a central organization, most often either a government agency or a private or not-for-profit entity operating a health plan.

How it works
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[7]:

Premium: The amount the policy-holder pays to the health plan each month to purchase health coverage.
Deductible: The amount that the policy-holder must pay out-of-pocket before the health plan pays its share. For example, a policy-holder might have to pay a $500 deductible per year, before any of their health care is covered by the health plan. It may take several doctor's visits or prescription refills before the policy-holder reaches the deductible and the health plan starts to pay for care.
Copayment: The amount that the policy-holder must pay out of pocket before the health plan pays for a particular visit or service. For example, a policy-holder might pay a $45 copayment for a doctor's visit, or to obtain a prescription. A copayment must be paid each time a particular service is obtained.
Coinsurance: Instead of paying a fixed amount up front (a copayment), the policy-holder must pay a percentage of the total cost. For example, the member might have to pay 20% of the cost of a surgery, while the health plan pays the other 80%. Because there is no upper limit on coinsurance, the policy-holder can end up owing very little, or a significant amount, depending on the actual costs of the services they obtain.
Exclusions: Not all services are covered. The policy-holder is generally expected to pay the full cost of non-covered services out of their own pocket.
Coverage limits: Some health plans only pay for health care up to a certain dollar amount. The policy-holder may be expected to pay any charges in excess of the health plan's maximum payment for a specific service. In addition, some plans have annual or lifetime coverage maximums. In these cases, the health plan will stop payment when they reach the benefit maximum, and the policy-holder must pay all remaining costs.
Out-of-pocket maximums: Similar to coverage limits, except that in this case, the member's payment obligation ends when they reach the out-of-pocket maximum, and the health plan pays all further covered costs. Out-of-pocket maximums can be limited to a specific benefit category (such as prescription drugs) or can apply to all coverage provided during a specific benefit year.
Capitation: An amount paid by an insurer to a health care provider, for which the provider agrees to treat all members of the insurer.
In-Network Provider: A health care provider on a list of providers preselected by the insurer. The insurer will offer discounted coinsurance or copayments, or additional benefits, to a plan member to see an in-network provider. Generally, providers in network are providers who have a contract with the insurer to accept rates further discounted from the "usual and customary" charges the insurer pays to out-of-network providers.
Prescription drug plans are a form of insurance offered through some employer benefit plans in the US, where the patient pays a copayment and the prescription drug insurance part or all of the balance for drugs covered in the formulary of the plan.

Some, if not most, health care providers in the United States 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. The insurance company pays out of network providers according to "reasonable and customary" charges, which may be less than the provider's usual fee. The provider may also have a separate contract with the insurer to accept what amounts to a discounted rate or capitation to the provider's standard charges. It generally costs the patient less to use an in-network provider.

Health plan vs. health insurance
Historically, HMOs tended to use the term "health plan", while commercial insurance companies used the term "health insurance". A health plan can also refer to a subscription-based medical care arrangement offered through health maintenance organization, HMO, PPO, or POS plan. These plans are similar to pre-paid dental, pre-paid legal, and pre-paid vision plans. Pre-paid health plans typically pay for a fixed number of services (for instance, $300 in preventive care, a certain number of days of hospice care or care in a skilled nursing facility, a fixed number of home health visits, a fixed number of spinal manipulation charges, etc.) The services offered are usually at the discretion of a utilization review nurse who is often contracted through the managed care entity providing the subscription health plan. This determination may be made either prior to or after hospital admission (concurrent utilization review).

[edit] Inherent problems with insurance
Insurance systems must typically deal with two inherent challenges: adverse selection, which affects any voluntary system, and ex-post moral hazard, which affects any insurance system in which a third party bears major responsibility for payment, whether that is an employer or the government. Some national systems with compulsory insurance utilize systems such as risk equalization and community rating to overcome these inherent problems.

[edit] Adverse selection
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 $40. (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. However, when the pool is self-selecting rather than random, as is the case with individuals seeking to purchase health insurance directly, adverse selection is a greater concern.[8] A disproportionate share of health care spending is attributable to individuals with high health care costs. In the US the 1% of the population with the highest spending accounted for 27% of aggregate health care spending in 1996. The highest-spending 5% of the population accounted for more than half of all spending. These patterns were stable through the 1970s and 1980s, and some data suggest that they may have been typical of the mid-to-early 20th century as well.[9][10] A few individuals have extremely high medical expenses, in extreme cases totaling a half million dollars or more.[11] Adverse selection could leave 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 employ medical underwriting, using a patient's medical history to screen out those whose pre-existing medical conditions pose too great a risk for the risk pool. 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 large financial burdens are denied coverage or charged high premiums to compensate.[12] One large US industry survey found that roughly 13 percent of applicants for comprehensive, individually purchased health insurance who went through the medical underwriting in 2004 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.[13] Among those who were offered coverage, the study found that 76% received offers at standard premium rates, and 22% were offered higher rates.[14] On the other side, applicants can get discounts if they do not smoke and are healthy.[15]

Health insurance in Canada
Most health insurance in Canada is administered by each province, under the Canada Health Act, which requires all people to have free access to basic health services. Collectively, the public provincial health insurance systems in Canada are frequently referred to as Medicare. Private health insurance is allowed, but the provincial governments allow it 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 are free to use private insurance for elective medical services such as laser vision correction surgery, cosmetic surgery, and other non-basic medical procedures. Some 65% of Canadians have some form of supplementary private health insurance; many of them receive it through their employers.[17] Private-sector services not paid for by the government account for nearly 30 percent of total health care spending.[18]

In 2005, the Supreme Court of Quebec ruled, in Chaoulli v. Quebec, that the province's prohibition on private insurance for health care already insured by the provincial plan could constitute an infringement of the right to life and security if there were long wait times for treatment as happened in this case. Certain other provinces have legislation which financially discourages but does not forbid private health insurance in areas covered by the public plans. The ruling has not changed the overall pattern of health insurance across Canada but has spurred on attempts to tackle the core issues of supply and demand and the impact of wait times.[19]

Health insurance in the Netherlands
In the Netherlands in 2006, a new system of health insurance came into force. All insurance companies have to provide at least one policy which meets a government set minimum standard level of cover and all adult residents are obliged by law to purchase this cover from an insurance company of their choice.

The new system avoids the two pitfalls of adverse selection and moral hazard associated with traditional forms of health insurance.

In the Dutch system, insurance companies are compensated for taking on high risk individuals because they receive extra funding for them. This funding comes from an insurance equalization pool run by a regulator which collects salary based contributions from employers (about 45% of all health care funding) and funding from the government for people whose means are such that they cannot afford health care (about 5% of all funding). Thus insurance companies find that insuring high risk individuals becomes an attractive proposition. All insurance companies receive from the pool, but those with more high risk individuals will receive more from the fund. The remaining 45% of health care funding comes from insurance premiums paid by the public. Insurance companies compete for this money on price alone. The insurance companies are not allowed to set down any co-payments or caps or deductibles. Neither are they allowed to deny coverage to any person applying for a policy or charge anything other than their nationally set and internet published standard policy premiums. Every person buying insurance from that company will pay the same price as everyone else buying that policy. And every person will get the minimum level of coverage. Children under 18 are insured for free (the funding coming from the equalization pool).

In addition to this minimum level, companies are free to sell extra insurance for additional coverage over the national minimum, but extra risks for this are not covered from the insurance pool and must therefore be priced accordingly.

Health insurance in the United Kingdom
Main article: National Health Service
Great Britain's National Health Service (NHS) is a publicly funded healthcare system that provides coverage to everyone normally resident in the UK. The NHS provides the majority of health care in England, including primary care, in-patient care, long-term health care, ophthalmology and dentistry. 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. Recently the private sector has been increasingly used to increase NHS capacity despite a large proportion of the British public opposing such involvement.[20]. According to the World Health Organization, government funding covered 86% of overall health care expenditures in the UK as of 2004, with private expenditures covering the remaining 14%.[21] The costs of running the NHS (est. £104 billion in 2007-8)[22] are met directly from general taxation.

The National Health Service Act 1946 came into effect on 5 July 1948. The UK government department responsible for the NHS is the Department of Health, headed by a Secretary of State for Health (Health Secretary), who sits in the British Cabinet. The NHS is the world's largest health service, and the world's third largest employer[23] after the Chinese army and the Indian railways.

关于保险的受益论文

对我国保险公估业发展的探讨论文编号:JR040摘要保险公估业的产生可追溯到300多年前的英国。目前,保险公估人的制度在欧美等发达国家已经日臻完善了。在国际上来看,目前由于专业化分工的加强,保险公司80%以上的查勘理赔评估业务已交由保险公估人承担。保险公估业的发展已成为保险市场规模扩大的必然趋势。我国当前保险中介市场仍处于初步阶段,而作为保险中介之一的保险公估却长期处于缺位、不被重视的状态。公估在保险运营中除了起到公正公平的作用之外,也是防灾减损的重要角色。然而保险公估人的这种性质却不被社会所认知与肯定。保险公估人的壮大将有利于保险市场的健康发展,他将使得市场更健康及透明化,真正地保护被保险人或受益人的合法权益,在受损时得到更公平公正的补偿与保护。但随着保险市场的发展,保险公司大而全的经营模式已无法使保险理赔等各环节都保持专业化及高服务水平。同时,保险公司如此经营模式也抑制了公估市场的发展,并导致了种种问题,如公估市场规模小,经营不规范,市场认可度不高、公估人普遍素质水平不高等。本文将针对目前保险公估市场发展存在的问题,利用专业化分工理论探讨其存在的必要性,并以此提出公估市场发展的建议。关键词:保险公估保险公估人发展困境专业化分工目录摘要11绪论41.1研究背景41.2研究思路41.3研究方法42我国保险公估业发展概述52.1保险公估的概念52.2我国保险公估市场发展概况52.2.1我国保险公估市场的兴起52.2.2近几年保险公估公司总体经营情况概述63当前我国保险公估业的发展困境73.1国家关于保险公估人的法律地位不明确73.2保险公估人自我定位模糊,盲目打价格战83.2.1自我定位不明确,经营不善93.2.2盲目价格竞争93.3专业水平低,公估人才缺乏94我国保险公估存在问题的成因104.1专业化分工理论104.2保险公司习惯于“大而全、小而全”一条龙式的经营模式124.3公估公司立足分工细化,但专业化水平仍不高134.4社会忽视保险公估的存在是实现专业化的需求145我国保险公估业发展模式145.1确立保险公估人的法律地位,增强社会认可度145.2加强与保险公司的合作155.3提高公估公司本身的经营能力及服务水平165.3.1摸索新的经营方式,开创新的经营理念165.3.2吸收培养高素质人才,提高专业服务水平17致谢18参考文献19英文文摘20以上回答来自:
