Health insurance and healthcare

5 min read

Unlike many countries, the US has no universal health system for most people. Insurance protects you from very high medical bills.

How coverage works

Insurance means paying a monthly premium; when you get care you may still pay a deductible and copays. In exchange, the insurer covers large costs.

Ways to get covered

Many people get insurance through a job. Others buy it on the government Marketplace (Healthcare.gov), and lower-income families may qualify for Medicaid or children’s programs (CHIP).

Quick tips

• There is an annual open-enrollment window — do not miss it.
• A new job or move can open a special enrollment period.
• Keep an insurance card with you.

If you are uninsured

Community health centers offer low-cost care regardless of insurance, and hospitals must stabilize emergencies. But routine care without insurance is costly — get covered as soon as you can.

Key terms

Premium (monthly cost), deductible (what you pay before insurance starts), copay (a flat fee per visit), and network (the doctors your plan covers).
