What Is Health Insurance?
Health insurance is a financial protection plan that pays for your medical expenses when you get sick, injured, or hospitalized. Instead of paying huge hospital bills from your pocket, the insurance company covers the cost (fully or partly), depending on your policy.
It includes coverage like:
- Hospitalization
- Surgeries
- ICU charges
- Medicines and diagnostics
- Cashless treatment in network hospitals
In simple words: Health insurance protects your savings and gives you access to quality healthcare without financial stress.

How to Choose the Right Health Insurance Company
If you want a policy that actually works during emergencies, compare these points:
1. Claim Settlement Ratio
Higher CSR = faster and smoother approval.
2. Cashless Hospital Network
Check hospitals available in your city. Cashless treatment reduces hassle.
3. Premium vs Coverage
Low premium is useless if the coverage is weak. Always check:
- Room rent limit
- Day-care coverage
- Pre and post hospitalization
- Pre-existing disease cover
4. Waiting Periods
Shorter waiting periods = better value.
5. Lifetime Renewability
Must-have. Never buy a policy that stops at age 60 or 65.
6. Digital Support
Fast online claim tracking = less stress during medical emergencies.
