What Is Your Sum Insured Actually Worth?

The number on the cover of your policy is a ceiling, not a promise. Here is the gap between the ten lakhs you think you bought and the rupees that actually reach the hospital.

Meera's father went in for a heart procedure in Pune. An angioplasty, two stents, four nights in hospital, one of them in the ICU. The final bill came to about ₹6,00,000.

He was covered. So was the man in the next room, and the woman down the corridor. All three families held a health policy with a sum insured of ₹10,00,000. All three had paid their premiums on time. None of the three got the same amount back.

One family was reimbursed nearly the whole ₹6,00,000. One got back a little under ₹4,90,000. One got about ₹4,20,000. Same illness, same bill, same headline cover of ten lakhs. Three very different cheques, and not one rupee of the difference was a rejection. No fraud, no dispute, no missing document. Just three policies doing exactly what their wordings said they would do.

This is the thing nobody explains when they sell you a number. Ten lakhs is the most the policy will ever pay across the year. It is not what it pays for this claim. Between the ceiling and the cheque sits a series of clauses, most of them invisible at the point of sale, and they decide the gap.

Let us walk the same ₹6,00,000 bill through the three policies and watch where the money leaks.

Policy A: the clean one

The first family's policy paid the room at actuals, had no co-payment, and put no sub-limit on the kind of treatment Meera's father needed.

Their claim was simple. The hospital billed ₹6,00,000, the insurer knocked off a few thousand for non-payable items (the bottle of sanitiser, the attendant's meals, a couple of administrative charges that every policy excludes), and paid the rest. The family was out of pocket by maybe ₹8,000 to ₹10,000 on a six lakh bill.

This is what people imagine all insurance does. It is also the rarest of the three.

Policy B: the room-rent trap

The second family's policy looked almost identical on the brochure. Ten lakh cover, cashless hospitals, the usual. Buried in the wording was one line: the room was covered up to the "single private AC room" category, and the hospital they used priced that category at ₹6,000 a night.

They booked a slightly nicer room at ₹9,000 a night. Nobody at the admission desk warned them, because warning you is not anyone's job.

Here is what that ₹3,000 a night actually cost them. Most health policies contain a clause called proportional deduction. The logic is that if you choose a room above your eligible category, the hospital tends to charge more for everything that scales with the room, the surgeon's fee, the operation theatre, nursing, monitoring. So the insurer pays those linked charges only in the same proportion as your room entitlement.

Their room entitlement was ₹6,000 against a ₹9,000 room, a ratio of two-thirds. So the insurer paid only two-thirds of a large slice of the bill. On roughly ₹3,00,000 of room-linked charges, that single choice lopped off about ₹1,00,000. Add the capped room itself and the usual non-payables, and the family that thought it had the same ten lakh cover got back a little under ₹4,90,000.

They lost more than a lakh of rupees not to an exclusion, not to a waiting period, but to a room category they did not know they had to check. The cap was never on the room alone. It reached into the entire bill.

A ₹6,00,000 hospital bill on a ₹10,00,000 policy. About ₹10,000 in non-payable items and about ₹1,00,000 in proportional deduction leave roughly ₹4,90,000 reaching the hospital.

Policy C: the regulator's floor

The third family had bought the cheapest plan, a standardised product whose terms are set by the regulator rather than the insurer. It is an honest plan in many ways, but it is built tight, and the tightness is all in the mechanics.

Three of them hit this claim at once. The room was capped at two per cent of the sum insured per day with a hard ceiling of ₹5,000, so the ₹9,000 room again triggered proportional deduction, this time at a steeper ratio. The ICU had its own cap. And on top of everything, the policy carried a flat five per cent co-payment, which means the family pays five per cent of every approved claim, no matter what.

So the bill was first cut down by the room proportioning, then the admissible amount was reduced by another five per cent that the family had to bear themselves. The cheque came to about ₹4,20,000. On a six lakh bill. On a ten lakh policy.

Again, nothing was rejected. The policy paid precisely what it promised. The family simply never knew what it had promised.

The same number, three different products

Put the three side by side and the lesson is hard to miss.

Three families. One illness. One bill of ₹6,00,000. Cover of ₹10,00,000 each. Cheques of roughly ₹5.9 lakh, ₹4.9 lakh and ₹4.2 lakh.

The sum insured told you almost nothing about which family ended up where. What decided it were the clauses underneath: the room rent basis, proportional deduction, the co-payment, the sub-limits. These are the parts no salesperson leads with, because the headline number sells and the mechanics do not.

If you remember one thing, remember this. When you compare two policies on their sum insured, you are comparing the size of two buckets while ignoring the holes in the bottom.

The clauses that drain the bucket

You do not need to memorise an eighty-page document. You need to find a handful of clauses, because these are the ones that move the cheque.

Room rent basis. Is your room covered at actuals, capped to a named category, or capped to a rupee figure or a percentage of cover per day? Anything other than "at actuals" can pull the whole bill down through proportional deduction. This is usually the single biggest leak.

Co-payment. A percentage of every claim that you pay yourself. Some policies have none. Some apply it only above a certain age. Some, like the regulator's floor plan, apply a flat slice to every claim for everyone. Five per cent does not sound like much until it is five per cent of every hospitalisation for the rest of your life.

Sub-limits. Caps on specific things inside the overall cover. Cataract surgery limited to twenty-five per cent of the sum insured or ₹40,000 an eye, whichever is lower. A list of "modern treatments" like robotic surgery sharing one pot capped at half your cover. A daily cap on the ICU. Each one is a smaller ceiling hiding under the big one.

Deductibles. An amount you agree to bear before the policy starts paying. Sometimes you choose this to lower your premium, which is fine if you know it is there and a nasty shock if you do not.

Find those four and you know more about your real cover than the brochure ever told you.

The other direction: when the number is bigger than it looks

To be fair, the clauses do not only cut. A few of them grow your cover, which is why two ten lakh policies can differ on the upside too.

Restoration refills your sum insured after you have used it, so a second hospitalisation in the same year is not left uncovered. But read how it triggers. Some plans restore only after you have fully exhausted the cover, which does not help if your first claim used eighty per cent and the second needs forty. Some restore even on partial use. Some let you reuse the restored amount for the same illness, some do not. The word "restoration" on a brochure tells you none of this.

No-claim bonus, under whatever name a given insurer uses, grows your cover for every year you do not claim. The questions that matter are how fast it grows, how high it can climb, and whether it survives a claim or collapses the year you finally use the policy. A bonus that vanishes the moment you need it is worth far less than one that holds.

Here, too, silence is data. If a policy says nothing about restoration, do not assume it has it. Assume it does not, and check.

What to actually do

Before you sign, stop reading the sum insured as the answer and start treating it as the question. Then ask three things.

What is my room rent basis, and does this policy use proportional deduction? If yes, the cheapest looking plan can become the most expensive at the counter.

What will I pay myself on a claim, once I add up co-payment, sub-limits and any deductible? That is your real exposure, and it has nothing to do with the headline cover.

And on the upside, does my cover refill if I claim twice in a year, and does my bonus survive a claim? Two policies with the same number can be a year apart in what they actually deliver.

Meera's father recovered. The families who got back ₹4.9 lakh and ₹4.2 lakh covered the rest from savings, the way most Indian households quietly do, and most of them still believe they had ten lakhs of cover. They did, on paper. The paper was never the point.

Next in this series: the other half of the surprise at the counter. Not how much your policy pays, but when it is actually willing to pay at all.
