What is Health Insurance?

Health insurance is a type of insurance policy that pays a portion of medical expenses. For instance, if you need to visit a doctor, have surgery, purchase prescription drugs or get medical tests (like x-rays), health insurance will pay a portion of the expenses incurred. The portion of expenses paid varies by policy.
Vaccines, check-ups, routine physical exams—each is important to maintaining health. But those without health insurance are less likely to receive potentially life-saving preventive care.
