What is Health Insurance?

Definition of Health Insurance

Health insurance is a contract between an individual and an insurance company in which the insurer agrees to cover some or all of the insured person’s medical expenses in exchange for a premium.

How Health Insurance Differs from Other Insurance Types

Unlike life or auto insurance, health insurance is specifically designed to cover the costs associated with medical care, such as doctor visits, hospital stays, and prescription medications.

Importance of Health Insurance

Financial Protection

Health insurance provides a financial safety net against high medical costs, protecting you from significant out-of-pocket expenses.

Access to Health Care

With health insurance, you gain access to a network of healthcare providers and facilities, ensuring timely and appropriate medical care.

Preventive Care

Many health insurance plans cover preventive services, such as vaccinations and screenings, which can help detect health issues early and reduce overall healthcare costs.

Types of Health Insurance Plans

Private Health Insurance

Private health insurance is provided by private companies and can be obtained through employers or purchased individually.

Public Health Insurance

Public health insurance includes government-funded programs like Medicare, Medicaid, and the Children’s Health Insurance Program (CHIP).

  • Preferred Provider Organizations (PPOs)

High-Deductible Health Plans (HDHPs)

HDHPs are characterized by higher deductibles but lower premiums, often paired with Health Savings Accounts (HSAs).
