Health insurance is a kind of insurance wherein the insurance company pays the medical costs of the insured individual if the individual in question falls ill due to covered causes, or due to accidents. The insurer may be a private organization or a government agency. The major purpose of health insurance is to cover medical expenses and any lost income while the individual is not well and unable to function normally.

There are different types of health insurance policies. The two most common ones are major medical and disability insurance. A major medical health insurance policy provides benefits for sickness or injury, irrespective of whether the care is provided at a doctors office, clinic or hospital. The types of sickness and injury covered are typically broad, although there are always limitations that you may want to discuss with your agent prior to purchasing the coverage. Major medical policies normally have an annual deductible and a lifetime maximum amount of benefits that will be paid.

Even if you are covered by a group insurance at work, you might consider taking an individual policy if you may change jobs soon, or if certain benefits that are not provided in the group policy.

A deductible is an annual amount that you will have to pay per insured person, before the insurance company begins to pay on your bills. There is an upper limit for the maximum amount of deductibles you will have to pay in a given year.

In a health policy, coinsurance refers to the percentage of the medical bills that the insured individual will have to pay after the deductible is met. Usually the health policy would have a provision called a stop-loss this is the maximum amount you will have to pay for covered medical bills.
