What Is Health Insurance?
Health Insurance — also called Health coverage
Health insurance is a type of coverage that helps pay for medical care, including doctor visits, hospital stays, prescription drugs, preventive care, and other healthcare services. Instead of paying the full cost yourself, you typically share costs with your health insurance plan through premiums, deductibles, copayments, or coinsurance.

What is health insurance?
Health insurance helps protect you from the high cost of medical care.
When you have health insurance, your plan pays part of the cost of covered healthcare services. In return, you may pay a monthly premium and share some costs when you receive care.
Health insurance can be provided through an employer, purchased directly from a private insurer, obtained through the Health Insurance Marketplace®, or provided through government programs such as Medicare, Medicaid, TRICARE, or VA health care.
How health insurance works
Although every plan is different, most health insurance works the same way.
- You enroll in a health insurance plan.
- You pay a monthly premium to keep your coverage active.
- When you receive covered medical care, the insurance company pays part of the cost.
- Depending on your plan, you may also pay a deductible, copayment, coinsurance, or other out-of-pocket costs.
Most plans include a network of doctors, hospitals, and other healthcare providers. Using in-network providers often costs less than receiving care outside the network.
What does health insurance cover?
Covered services vary by plan but commonly include:
- Primary care visits
- Specialist care
- Hospital stays
- Emergency care
- Preventive services
- Prescription drugs
- Laboratory tests
- Mental health services
- Maternity care
- Rehabilitation services
Some services may require prior authorization or referrals depending on your health plan.
Where can you get health insurance?
People obtain health insurance in several ways.
Common sources include:
- Employer-sponsored health insurance
- Health Insurance Marketplace® plans
- Medicare
- Medicaid
- Children's Health Insurance Program (CHIP)
- TRICARE

The best option depends on your age, income, employment, military service, disability status, and other eligibility factors.
Health insurance vs. health care
These terms are often confused, but they are different.
Health insurance helps pay for healthcare services.
Health care is the actual medical treatment you receive from doctors, hospitals, clinics, pharmacies, and other healthcare providers.
Having health insurance can make healthcare significantly more affordable, but it does not eliminate all medical costs.
Why this matters
Medical expenses can be unpredictable and expensive. Health insurance helps reduce the financial impact of illness or injury while making preventive care and routine medical services more accessible. Understanding how your coverage works can also help you avoid unexpected medical bills.
In real life
- An employee enrolls in their company's health insurance plan during open enrollment and pays a monthly premium through payroll deductions.
- A retiree receives health coverage through Medicare after turning 65.
- A family with limited income qualifies for Medicaid, reducing the cost of healthcare and prescription medications.
