1. Introduction to Health Insurance
Healthcare costs are rising globally, making health insurance more vital than ever. In 2025, medical technology, telehealth, and chronic disease rates are rapidly evolving. This makes understanding health insurance a necessary skill for financial planning, health protection, and peace of mind.
2. What is Health Insurance?
Health insurance is a contract between an individual and an insurance provider that offers financial protection against medical expenses. It can cover:
- Doctor visits
- Hospital stays
- Surgeries
- Prescription drugs
- Preventive services
- Mental health services
Policyholders pay a premium, and the insurer shares or fully covers eligible medical costs based on the policy’s terms.

- Legal Compliance: In many countries, health insurance is required.

| Deductible | You pay this amount before insurance kicks in. |
| Copay | Set fee per service or drug. |
