A hospital stay in a good Indian city can now cost more than a year's savings for many families. Health insurance is meant to stop that from happening. But two policies with the same premium and the same headline cover can behave very differently when you actually make a claim. The differences sit in the small print.
Sum insured: how much is enough
This is the most the insurer will pay in a policy year. A cover of ₹5 lakh may be fine in a small town but runs out quickly in a metro for anything involving surgery or intensive care. Many advisers suggest at least ₹10 lakh to ₹25 lakh for a family in a large city. Think about the city where you'd be treated, not where you live on paper.
Don't stretch the base policy to a huge amount, though. A cheaper way to get a large cover is a super top-up, covered below.
The clauses that trip people up
| Term | What it means | What to look for |
|---|---|---|
| Room rent limit | A cap on the room you can take, often a percentage of the sum insured or a fixed amount per day | Prefer no cap, or a high one. A cap can also reduce other charges in proportion. |
| Co-payment | You pay a fixed share of every claim | Zero co-pay if you can afford the premium |
| Waiting period | Time before certain conditions are covered | Shorter is better. Check rules for pre-existing conditions and for named procedures. |
| Sub-limits | Caps on specific treatments such as cataract or joint replacement | Avoid policies with many sub-limits |
| Restoration | Refills the sum insured if you use it up in a year | Check whether it applies to the same illness |
| No-claim bonus | Extra cover for each claim-free year | Usually a nice-to-have, not a deciding factor |
| Cashless network | Hospitals where the insurer settles the bill directly | Check that hospitals near you are on the list |
Pre-existing conditions
Diabetes, high blood pressure, thyroid problems and anything else you already have when you buy the policy are "pre-existing". Insurers don't pay for them until a waiting period passes. IRDAI has been shortening these periods in recent years, so what applies to your policy depends on when you buy it and what the insurer's terms say. Read the policy wording, and always declare everything on the proposal form. Non-disclosure is the commonest reason for a rejected claim.
Individual or family floater
A floater gives one sum insured that the whole family can share, usually for a lower premium. It works well for a young family. A big claim by one member can use up most of the cover, though. Individual policies give each person a separate sum, which costs more but makes sense for older parents, who are more likely to claim. A common pattern is a floater for you, your spouse and children, and a separate policy for each parent.
Super top-up: the cost-effective upgrade
A super top-up plan pays only after your claims in a year cross a "deductible" you choose. Because it doesn't start until then, premiums are much lower than for a base policy of the same size.
You hold a ₹10 lakh base policy. You add a ₹40 lakh super top-up with a ₹10 lakh deductible. If a hospital bill is ₹30 lakh, your base policy pays the first ₹10 lakh and the top-up pays the remaining ₹20 lakh. You now have ₹50 lakh of total protection for a premium well below that of a ₹50 lakh base plan.
Employer cover is a bonus, not a plan
Group cover through your job is useful, but it usually ends when you leave, and age and pre-existing conditions make it harder to buy a good policy later. Keep an individual or family policy of your own, even if your employer provides one.
Switching and portability
You can move to a new insurer at renewal, and the credit for waiting periods you've already served can carry across, but only up to the earlier cover. Apply well before your renewal date and keep records of the existing policy. Don't let it lapse in between.
Reading the claim side
- Check the insurer's claim settlement record and complaint data, which IRDAI publishes.
- Find out how long cashless approvals take in practice.
- Keep every document: prescriptions, test reports, bills, discharge summary.
- If a claim is rejected, ask for the reason in writing. You can escalate to the insurer's grievance officer, then to the insurance ombudsman, and through IRDAI's complaint system.
Buying checklist
- Decide the sum insured for the city you'd be treated in.
- Choose no room-rent cap, zero co-pay and few sub-limits.
- Declare all medical history honestly.
- Consider a super top-up for large cover at a low cost.
- Set a renewal reminder and pay on or before the due date.
IRDAI rules on waiting periods, moratorium and claims have changed in recent years and may change again. The policy document and the insurer's current brochure are what actually govern your cover. Premium deductions under Section 80D apply only in the old tax regime.
