1. Injuries, illnesses, or other conditions for which a health insurance policy does not provide coverage. Exclusions exist because they are thought to be too risky for the health insurance provider. For example, many insurance providers exclude treatment for some types of cancer because they are so expensive to treat. See also: Pre-existing condition.

2. Income that is not considered gross income for tax purposes. Exclusions include gifts, inheritance, and some others. It is important to note that just because a type of income is an exclusion, it does not mean that it is not taxed; it simply may be taxed differently. Exclusions are stated in the U.S. Tax Code.


Medical services that insurance companies do not pay for are called exclusions. A typical exclusion is a wartime injury or a self-inflicted wound.

But coverage for certain pre-existing conditions, or health problems you had before you were covered by the policy, may also be excluded on some policies.


An amount of income that is not included in gross income because the Tax Code excludes it. Examples, include gain from a qualified sale of a principal residence, income earned abroad, and gifts and inheritances.
