Health Insurance

Health insurance is a 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.
Market-based health care systems such as that in the United States rely heavily on private and not-for-profit health insurance.

History and evolution

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. 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.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.

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.

• 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.

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), 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.

Inherent problems with private insurance
Any private insurance system will face two inherent challenges: adverse selection and ex-post moral hazard.

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 $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.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.On the other side, applicants can get discounts if they do not smoke and are healthy.

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,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.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
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.

Other factors affecting insurance prices
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.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.
