Underinsured on Health Cover? How to Pick the Right Sum Insured in India

A guide published by theweek.in asks whether Indian households are underinsured and how to choose the right health cover. The short answer for readers: if your total health cover would not comfortably absorb a serious hospital stay in your city, you are underinsured, and the fix is usually a larger sum insured, often through a top-up, rather than an entirely new policy.

The issue matters because a single unplanned admission can wipe out savings or push a family into borrowing. Checking your cover takes about an hour and can prevent a debt that takes years to repay.

This article explains how to test your cover, what the fine print does to it, and how to close a gap without overspending. We draw only on the headline reported by theweek.in and on standing rules of how Indian health insurance works; we have not reproduced the outlet's specifics.

Key takeaways

• Underinsurance means your cover, after deductions and limits, would not meet a realistic hospital bill in your city, not merely that you hold a policy.
• The sum insured on paper is not what you receive: room-rent caps, co-payments and non-payable items can shrink the payout.
• A super top-up over a base policy is usually the cheapest way to raise protection substantially.
• Employer group cover is useful but tends to end with the job, so it should not be your only shield.
• Buy early and disclose honestly: waiting periods and claim disputes are the most common sources of trouble.
• If cover falls short, borrowing to pay a bill is costly; compare the interest with the premium you could have paid.

What being underinsured actually means in India

Holding a health policy and being adequately covered are two different things. Underinsurance is the gap between what a treatment could cost and what your policy will actually pay. That gap has several sources: a sum insured that is too low, a policy that is shared across the whole family, restrictive sub-limits, and a co-payment that makes you bear a fixed share of every claim.

Medical costs in private hospitals in metros are far higher than in smaller towns, and they tend to rise faster than general prices. A cover that felt generous when bought several years ago may look thin today. Cashless treatment at a network hospital also matters, because reimbursement claims involve upfront payment and paperwork.

Who is most exposed? Households relying solely on a group policy from an employer, people with a family floater where one large claim can exhaust the shared limit, and older parents covered under a small plan are the most vulnerable. Younger, single individuals with a small cover are less exposed to a large bill in absolute terms, though a serious accident or illness can still exceed a low limit. Those with a substantial, well-structured cover plus a top-up are generally well placed.

How to work out the right sum insured

There is no single correct number, but a structured approach beats guessing. Start with the city where you would most likely be treated, because that sets the price of a hospital room, surgeon fees and intensive care. Then think about the family: how many members, their ages, and any existing conditions.

A commonly used rule of thumb among planners is that residents of large metros should look at a substantially higher cover than those in smaller cities, and that a family floater should be sized larger than an individual policy because several people share the limit. Treat this as a starting point, not a formula. Also consider that a policy bought today will have to serve you for many years while costs keep rising.

A practical way to test yourself:

1. Ask a nearby private hospital for the approximate package cost of a major but common procedure, such as a cardiac or orthopaedic surgery.
2. Add a margin for pre-admission tests, post-discharge care and items your policy may not pay.
3. Compare that total against the payable amount under your current policy after applying any room-rent cap and co-payment.
4. If the difference is uncomfortable, that is the size of the top-up to consider.

Remember that a larger sum insured also brings a higher premium, and premiums typically climb with age. The point is to buy protection you are likely to use in a bad year, not to insure against every imaginable scenario.

Base plan, top-up and super top-up compared

Most households do not need to replace their policy. They need to add a layer. The main choices work differently:

Option	How it pays	Typical use	Relative premium
Base policy	Pays from the first rupee, up to the sum insured	Everyday hospitalisation, cashless care	Highest per rupee of cover
Top-up	Pays once a single claim crosses the deductible	Large single bills	Lower per rupee of cover
Super top-up	Pays once total claims in the year cross the deductible	Multiple or large claims in one year	Lowest per rupee of cover
Employer group cover	Pays up to a limit set by the employer	Baseline cover while employed	Usually free to the employee

A super top-up with a deductible equal to your base cover is a popular pairing. For instance, a ₹5 lakh base policy with a ₹20 lakh super top-up over a ₹5 lakh deductible gives you protection up to ₹25 lakh, at a premium that is generally much lower than buying a ₹25 lakh base policy. The catch is that the top-up only activates after the deductible is crossed, so your base cover must be in place.

Worked example: one hospital bill, three covers

The numbers below are illustrative, built to show how the mechanics work and not taken from any report. Assume a hospital bill of ₹12 lakh, all of it payable under the policy.

Cover	Insurer pays	You pay	How it works out
₹5 lakh base only	₹5 lakh	₹7 lakh	Payout stops at the sum insured
₹5 lakh base + ₹20 lakh super top-up (₹5 lakh deductible)	₹12 lakh	Nil	Base pays ₹5 lakh, top-up pays the remaining ₹7 lakh
₹10 lakh base with 20% co-payment	₹9.6 lakh	₹2.4 lakh	20% of ₹12 lakh is ₹2.4 lakh, leaving ₹9.6 lakh, which is within the ₹10 lakh limit

If the ₹7 lakh shortfall in the first row were financed through borrowing, the cost would rise further. A three-year loan at 13 percent would mean an EMI of roughly ₹23,600 and total interest near ₹1.5 lakh. You can test similar figures with the EMI calculators and see how personal loan terms compare before you ever need one.

Policy clauses that quietly shrink your cover

Two policies with the same sum insured can behave very differently. Read the schedule for these terms:

• Room-rent limit: if you choose a room costlier than the cap, many policies reduce other charges proportionately, which can cut the payout well beyond the room difference.
• Co-payment: a fixed percentage of every claim that you bear, common on policies aimed at senior citizens.
• Sub-limits: caps on specific treatments or conditions that sit below the overall sum insured.
• Waiting periods: an initial waiting period after purchase, and longer ones for pre-existing conditions and certain planned procedures. Under IRDAI norms these have been shortened over time, but they still exist.
• Non-payable items: consumables and some administrative charges are often excluded, so the bill you owe can exceed the amount you expect.
• Restoration and no-claim bonus: features that refill or grow your cover; useful, but check how they apply to floaters.

The insurance regulator, IRDAI, sets the framework for policy terms and claim handling, and its rules on matters such as waiting periods and the period after which a claim cannot be denied for non-disclosure have been revised in recent years. Check the current position with your insurer before relying on any particular period.

What to do this month

You do not need to overhaul everything at once. A short, ordered checklist works better:

1. Pull out every policy you hold, including employer cover, and note the sum insured, renewal date and exclusions.
2. Identify the room-rent cap and any co-payment, and estimate your real payable amount for a large claim.
3. Get a quote for a super top-up with a deductible matching your base cover.
4. Confirm that your parents, if dependent, have their own adequate cover rather than sharing your floater.
5. Set aside a small emergency fund for non-payable items and pre-cover costs.
6. Diarise the renewal, and review the cover after any major life change such as a marriage, a child or a move to a costlier city.

Common mistakes to avoid

Some errors recur among policyholders:

• Relying only on employer cover and discovering, after a job change, that there is no continuity.
• Buying the cheapest premium without reading the room-rent cap or co-payment.
• Hiding a pre-existing condition, which can lead to a rejected claim later.
• Letting a policy lapse, which can restart waiting periods on a fresh purchase.
• Choosing a small cover for elderly parents to save on premium, then facing a large bill when they are most likely to need care.
• Treating tax savings as the goal; the deduction under Section 80D can help, but the real purpose is protection.

Buying earlier is generally cheaper and simpler than waiting until a health issue appears, because premiums rise with age and new conditions may attract exclusions.

Frequently asked questions

How do I know if my health insurance is enough?

Compare the likely cost of a major treatment at a private hospital in your city with what your policy would actually pay after room-rent caps, co-payments and exclusions. If the difference is large, you are underinsured. Family size and age also affect how much cover you need.

Is a super top-up better than buying a bigger base policy?

For many households, yes, because it usually costs less per rupee of cover. It works only after your deductible is crossed, so you still need a base policy or employer cover. It suits people who want protection against large bills rather than everyday claims.

Is employer health insurance enough?

It is a useful baseline but rarely sufficient on its own. The sum insured may be modest, it is often shared across the family, and it usually ends when you leave the company. Holding a personal policy alongside it gives continuity.

What if I cannot afford a larger cover?

Start with a smaller top-up, choose a higher deductible to lower the premium, and keep an emergency fund. Avoid dropping cover altogether, since an uninsured bill is usually financed through expensive borrowing.

Does buying insurance earlier really help?

Yes. Waiting periods run from the date a policy starts, and premiums are lower at younger ages. Buying before any health condition emerges also reduces the risk of exclusions.
