What Is Health Insurance?
Health insurance is an agreement with a company or government program that helps pay for healthcare. You or your employer pay for the plan, and in return the plan helps cover eligible healthcare expenses, such as doctor visits, tests, hospital care, and medications.
When you receive care, your healthcare provider sends the bill to your insurance. The plan pays its share based on its rules. You may still pay part of the cost — for example, a copayment at a visit or the amount left after insurance pays.
Coverage differs between health plans. Two people with insurance from the same company may have different benefits, costs, and approved healthcare providers. Your plan documents explain what your plan covers.
