Why Health Insurance Plans May Not Be Enough for Rising Medical Costs

A ₹5 lakh health policy can feel generous on the day you buy it. Ten years later, the same policy may struggle to cover one major surgery at a good private hospital. Your sum insured stays fixed for the year, while hospital charges, newer treatments and costlier procedures keep pushing the bill up. The question worth asking isn’t whether you’re insured, but whether you’re insured for what treatment costs now.

The Gap Between Your Sum Insured and Real Bills

The sum insured is the maximum your insurer will pay in a policy year. It isn’t a guaranteed payout, and once claims reach that limit, anything further comes out of your pocket. For a single person in their thirties, a modest amount may last a while. For a family floater covering four people, one serious illness can use most of it.

Many people bought their health insurance years ago and never revisited it. Incomes, family size and hospital preferences change, but the sum insured often doesn’t. That mismatch is often why a policy feels inadequate exactly when you need it.

Why Treatment Keeps Getting Costlier

Hospital costs rise for several reasons. Newer diagnostic tests, robotic and minimally invasive surgery, advanced cancer drugs and better intensive care all improve outcomes, but they also cost more. Room rent, doctors’ fees and consumables tend to rise over time too. People are also living longer, which means more years in which you might need treatment, often at an age when both premiums and medical needs are higher.

City matters as well. Treatment at a large private hospital in a metro usually costs more than the same procedure in a smaller town. If you’d want to be treated at a particular hospital, look up what common procedures cost there and use that as your reference point rather than a national average.

How a Super Top-Up Fills the Gap

One affordable way to raise your cover is to add a super top up health insurance policy. It works alongside your base policy and pays once your total admissible medical expenses in a policy year cross a threshold called the deductible. Below that amount, the super top-up pays nothing.

Say your base policy is ₹5 lakh and you buy a super top-up with a ₹5 lakh deductible. In this illustration, if you have two hospital stays costing ₹4 lakh and ₹3 lakh in one year, the base policy can pay up to ₹5 lakh and the super top-up can pay the remaining ₹2 lakh, subject to policy terms. Because claims below the deductible aren’t the super top-up’s concern, premiums are usually much lower than for a base policy of the same size.

Top-Up or Super Top-Up: The Difference

A regular top-up usually looks at each hospitalisation separately. It pays only when a single claim crosses the deductible. A super top-up adds up all admissible claims in the year, so several smaller bills can together cross the threshold.

That difference matters for families and older members who may be admitted more than once. Even so, features vary by insurer, so check whether the deductible is calculated per claim or on an aggregate basis before you buy.

Limits and Mistakes to Watch

A super top-up has its own waiting periods for pre-existing diseases and specific illnesses, and they may start fresh even if your base policy has already cleared them. It also carries its own exclusions, sub-limits and room rent rules, which may not match your base policy.

A common mistake is choosing a deductible higher than your base cover. If your base policy is ₹3 lakh and the deductible is ₹5 lakh, you’d have to pay the ₹2 lakh gap yourself before the super top-up starts paying. Another is assuming the super top-up will pay for something your base policy excludes. Each policy is assessed on its own terms.

Other Ways to Strengthen Your Cover

You can increase the sum insured on your base policy at renewal, though the insurer may underwrite the higher amount and apply fresh waiting periods to the increase. Some policies offer a cumulative bonus that raises the cover for each claim-free year, or a restoration benefit that refills the sum insured after a claim. These are policy-specific, so read the conditions carefully. If you’re buying cover for the first time, starting with a higher base sum insured can be simpler than trying to add to it later, when your health may have changed.

Group cover from your employer is useful, but it usually ends when you leave the job. Treat it as an addition to your own policy, not a replacement for one.

Checking Whether Your Cover Still Fits

Review your health cover every few years, and after any big life change such as marriage, a child or moving cities. Compare your sum insured with what a major procedure would cost at the hospital you’d choose, and check room rent limits, co-payments and sub-limits.

Before adding or changing any policy, read the policy wording and the Customer Information Sheet. Since 22 September 2025, individual health policies have been exempt from GST, which has made adding cover slightly cheaper than before.

Medical costs won’t wait for your policy to catch up. A regular review, and a well-chosen super top-up where it fits, helps keep your cover in step with the bills you’re likely to face.
