Health Insurance — Complete Buying Guide 2026
Sum insured, room rent, co-pay, cashless hospitals, super top-up, portability, and how to file claims.
A single hospitalisation in India can cost ₹5-15 lakh in a metro city. Without health insurance, this can wipe out years of savings. Here's how to choose the right policy.
How Much Sum Insured Do You Need?
| City Tier | Recommended Sum Insured | Reason |
|---|---|---|
| Metro (Mumbai, Delhi, Bangalore) | ₹10-25 lakh | Hospital costs are highest |
| Tier 2 (Pune, Jaipur, Lucknow) | ₹5-15 lakh | Moderate hospital costs |
| Tier 3 and rural | ₹3-10 lakh | Lower costs but inflation rising |
Instead of buying a ₹25L base plan (expensive), buy a ₹5L base plan + ₹20L super top-up with ₹5L deductible. You get ₹25L effective coverage at much lower premium.
Key Terms You Must Understand
Cashless vs Reimbursement
| Feature | Cashless | Reimbursement |
|---|---|---|
| Process | Hospital bills insurer directly | You pay, then claim refund |
| Hospitals | Only network hospitals | Any hospital |
| Speed | Pre-auth in 2-4 hours | Refund in 15-30 days |
| Hassle | Minimal paperwork | You manage all bills and claims |
Anita needs knee surgery. She chooses a network hospital from her insurer's list.
- Hospital sends pre-authorisation request to insurer
- Insurer approves ₹3.5L within 4 hours
- Anita gets surgery, hospital settles directly with insurer
- Anita pays only ₹2,000 for non-covered items (extra meals, phone charges)
Total out-of-pocket: ₹2,000 instead of ₹3.5L.
Super Top-Up — The Smart Strategy
Suresh has:
- Base health plan: ₹5L (premium ₹8,000/year)
- Super top-up: ₹20L with ₹5L deductible (premium ₹3,500/year)
Total coverage: ₹25L for ₹11,500/year. A standalone ₹25L policy would cost ₹22,000+/year. He saves ₹10,500 annually.
Portability — Switch Without Losing Benefits
IRDAI allows you to port your health insurance to a different insurer without losing waiting period credits. Key rules:
- Apply to the new insurer at least 45 days before renewal
- The new insurer can accept, reject, or modify terms
- Your accumulated waiting period credits transfer
- Sum insured can be maintained or increased (new insurer may apply fresh waiting for the increase)
What to Check Before Buying
- No room rent cap — Look for policies with no sub-limits on room rent
- No co-pay — Especially below age 60
- Restoration benefit — Sum insured restores if used up in a claim year
- Day care procedures — Over 500 procedures covered without 24-hour hospitalisation
- Network hospital list — Check if your preferred hospitals are covered
- Claim settlement ratio — Look for 90%+ in health insurance
- Free health check-up — Most policies offer annual check-ups after claim-free years
Company group health covers end when you leave or retire. Buy individual cover early when you are young and healthy — premiums are lower and you lock in benefits.
Key Takeaways
- Minimum ₹10L sum insured for metro residents
- Use super top-up to get high coverage at low cost
- Choose cashless facility over reimbursement for convenience
- Avoid policies with room rent limits and co-pay clauses
- Don't depend solely on employer health insurance — buy your own early
