Health insurance is a type of insurance coverage that covers the cost of an insured individual's medical and surgical expenses. Depending on the type of health insurance coverage, either the insured pays costs out-of-pocket and is then reimbursed, or the insurer makes payments directly to the provider.
In health insurance terminology, the "provider" is a clinic, hospital, doctor, laboratory, health care practitioner, or pharmacy. The "insured" is the owner of the health insurance policy; the person with the health insurance coverage.
In countries without universal health care coverage, such as the USA, health insurance is commonly included in employer benefit packages and seen as an employment perk.
