Health Insurance Guide: Choosing the Right Cover and Avoiding Bad Policies (India)

You are 28. You feel fine. You have never been hospitalised in your life. And that is exactly the mental trap that keeps most Indians uninsured until the year they need it most.

A single hospital stay for something as ordinary as dengue, appendicitis, or a fracture can run ₹1 to ₹3 lakh in a decent private hospital in any metro today. A cardiac event or a cancer diagnosis can run into double digits. Without a health policy, that bill comes straight out of your savings, your parents' savings, or a personal loan you did not plan for.

This guide walks you through exactly how much cover to buy, what the fine print actually means, the rule changes from 2024 and 2025 that changed the math in your favour, and how to pick a policy without getting fooled by a low premium that hides a weak one. By the end you will know exactly what a good ₹10 lakh policy looks like and why you need one even if your employer already covers you.

Say you just turned 28, you are healthy, and you are about to buy your first individual health policy. Here is everything that decision touches.

1. What health insurance actually does

A health insurance policy pays your hospital bills, up to a limit, in exchange for a yearly premium. That limit is called the sum insured. Everything else in this guide, room rent rules, waiting periods, no-claim bonus, is really just detail on how and when that sum insured actually gets paid out.

The mistake most first-time buyers make is picking a policy by premium alone. A cheap policy with a low sum insured, a tight room-rent cap, and long waiting periods can leave you paying out of pocket even though you technically "have insurance." The right way to shop is sum insured first, policy terms second, premium last.

Core rule: insurance you cannot actually use when you are sick is not insurance, it is a false sense of safety.

2. How much sum insured do you actually need?

For a single young adult in a metro city, ₹5 lakh is the bare minimum today and ₹10 lakh is the common, comfortable floor. Tier 2 and tier 3 cities can get away with slightly less because treatment costs less, but healthcare inflation is real everywhere and costs only go up.

Your situation	Suggested sum insured
Single, 20s, metro city	₹10 lakh
Single, 20s, tier 2/3 city	₹5 to 7 lakh
Married, planning a family	₹10 to 15 lakh (family floater)
Parents in their 50s/60s	₹15 to 25 lakh, separate policy from yours

If ₹10 lakh feels expensive to buy outright, look at a base policy of ₹5 lakh plus a super top-up of another ₹10 to ₹15 lakh. A super top-up kicks in once your base policy's claims cross a threshold (the deductible), and it is usually far cheaper per lakh of cover than simply buying one large base policy. This combination is how a lot of financially sharp people in their 20s get large cover without a large premium.

Core rule: buy for the worst realistic year, not an average year. One bad hospitalisation should never wipe out your savings.

3. The big 2025 change: GST on health insurance is now zero

Here is the single biggest tailwind working in your favour right now. Individual health insurance premiums in India became completely GST-exempt from 22 September 2025. Before that date, you paid 18% GST on top of your premium. Now you pay 0%.

This is not a small thing. On a ₹15,000 annual premium, that 18% used to add ₹2,700 straight to your bill. That entire amount is gone now, for individual policies, including individual family-floater plans. If you are comparing quotes and see one that still includes 18% GST, that insurer has not passed on the exemption and you should ask why, or walk.

One important carve-out: this GST exemption applies to individual policies only. Group or employer-sponsored health policies still attract 18% GST. That is one more reason an individual policy in your own name is worth having, on top of every other reason in this guide.

Core rule: the government just made buying your own health cover meaningfully cheaper. There has never been a better time to stop delaying.

4. Room rent capping and the rule that actually protects you now

This is the fine print that quietly destroys the most claims, and almost nobody reads it before they buy.

Many policies cap the room rent they will pay for, say, 1% of your sum insured per day. On a ₹5 lakh policy that is ₹5,000 a day. If you get admitted to a room that costs more than that cap, insurers historically applied something called "proportionate deduction," where every single charge on your bill, not just the room, got scaled down by the same ratio as the room-rent overshoot. Doctor's fees, ICU charges, surgery costs, nursing, all of it got cut proportionally, even though none of those charges had anything to do with your room choice.

The good news: the IRDAI Master Circular from 29 May 2024 changed this. Proportionate deduction can now apply ONLY to the room rent itself. Your surgeon's fee, ICU charges, operation theatre costs, and nursing charges must be paid in full regardless of which room you chose. This is a real, meaningful upgrade in your favour, and it applies to policies issued or renewed after the circular.

That said, do not treat this as a reason to stop caring about room-rent caps. A capped room rent still limits how much of your own daily room cost gets reimbursed, and it still nudges you toward a lower room category during a stressful hospital admission. The best policies still have no room-rent capping at all, meaning you can choose any room category and get it paid in full.

Room rent situation	Old rule (pre-2024)	Current rule (2024 onward)
You choose a room above the cap	ALL charges proportionately reduced	Only room rent is proportionately reduced
You choose a room within the cap	Full claim paid	Full claim paid
Policy has no room-rent cap	Not applicable	Choose any room, full claim paid

Core rule: a policy with zero room-rent capping is worth paying slightly more for. It removes an entire category of claim disputes.

5. Waiting periods: what you cannot claim for, and for how long

Every health policy has waiting periods. These are windows of time after buying (or after a condition arises) during which a related claim will not be paid. Understanding these matters more than almost anything else in the fine print, because this is where claims get rejected.

Waiting period type	Duration	What it means
Initial waiting period	30 days	No claims at all in the first 30 days except accidents
Pre-existing disease (PED)	Up to 36 months	Conditions you already had (diabetes, hypertension, thyroid, etc.) before buying
Specific ailments/procedures	Around 24 months	Named conditions like cataracts, hernia, piles, certain surgeries
Maternity (if covered)	Insurer-specific, often 9 months to a few years	Varies significantly by insurer and plan

The pre-existing disease waiting period used to run up to 48 months. IRDAI's 2024 rule reduced the maximum insurers can impose to 36 months. If you already have a condition like diabetes or high blood pressure, this matters directly: you are now free of that particular waiting clock a full year sooner than someone who bought the same type of policy a few years earlier.

At 28 and healthy, this section may feel abstract to you. It will not feel abstract if a condition shows up at 35 and you switch insurers, or if you bought a policy in a hurry and did not read this part. Buying young, before anything shows up on a medical report, is how you dodge this entirely.

Core rule: the day you're healthiest is the cheapest, cleanest day to buy. Waiting periods only bite people who delay.

6. Pre and post hospitalisation cover

A hospital bill is not just the days you spend admitted. Diagnostic tests, doctor consultations, and medicines before admission, and follow-up visits, medicines, and tests after discharge, all cost money too, and a good policy covers a defined window on both sides.

Typically this looks like 30 days of pre-hospitalisation expenses and 60 days of post-hospitalisation expenses, though many current plans extend post-hospitalisation cover to 90 or even 180 days. This detail varies by insurer and plan, so check it specifically rather than assuming. A policy with only 15 days pre and 30 days post leaves real costs, tests, consultations, follow-up medication, exposed. Longer windows protect more of your actual cost.

7. What is a no-claim bonus, and how does it work now?

If you go a full policy year without making a claim, insurers reward you with a no-claim bonus (NCB). Historically this meant your sum insured quietly grew each claim-free year at no extra premium cost, which is a genuinely good deal: free extra cover for staying healthy.

The rule has improved further. Post the 2024 IRDAI circular, on a claim-free year you can typically choose between a higher sum insured OR a discount on your premium, whichever suits you better that year. If you already feel your sum insured is generous, take the premium discount. If you want more cushion, take the higher cover.

One thing to watch: a claim in any year usually reduces or resets your accumulated NCB, so small claims for minor expenses can cost you more in lost bonus than they are worth. For genuinely small medical bills, it is often smarter to just pay out of pocket and preserve your no-claim status.

Core rule: do not file a claim for every small ailment. Save the claim for when the bill actually justifies losing your bonus.

8. Cashless Everywhere: what changed in 2024

Before 2024, cashless treatment, where the insurer settles directly with the hospital and you do not pay upfront, only worked at hospitals that had a specific tie-up (called a "network hospital") with your insurer. Go to a non-network hospital, even in an emergency, and you had to pay first and claim reimbursement later, which meant arranging a lakh or more in cash during a medical crisis.

"Cashless Everywhere," launched on 25 January 2024, changed this. You can now get cashless treatment at ANY hospital, not just network ones, as long as you inform the insurer within the required window: at least 48 hours before a planned admission, or within 48 hours of an emergency admission. The hospital is not obligated to accept it (some smaller or unlisted hospitals may still ask for reimbursement-mode instead), but for the vast majority of proper hospitals this removed a genuine, painful gap in coverage.

The same 2024 circular also tightened response times on the insurer's side: cashless authorisation must be given within 1 hour of the request, and final discharge approval within 3 hours. That is a direct fix to the old horror stories of families waiting for hours at the billing counter after a patient was medically ready to go home.

Core rule: always inform your insurer within 48 hours of any hospitalisation, planned or emergency, to keep the cashless option alive regardless of which hospital you're in.

9. The moratorium period: why 5 years matters

A moratorium period is the point after which an insurer can no longer reject or contest your claim over non-disclosure or misrepresentation, except in cases of proven fraud. Before the 2024 rule, this was 8 continuous years of coverage. It has since been reduced to 5 years.

Once you have held a health policy continuously (through renewals, even across insurers via portability) for 5 years, your policy becomes far harder to dispute on grounds of "you didn't mention X in your proposal form." This protects genuine policyholders from insurers digging through old medical history to deny a large claim years later.

10. Why you need your own policy even if your employer already covers you

If your company provides a group health policy, it feels tempting to skip buying your own. Do not. Here is exactly why that is a mistake.

Employer group cover	Your own individual policy
Ends the day you leave the job	Stays with you regardless of employer
Sum insured is often shared/limited across your family	Sum insured is fully yours
Waiting periods often reset if terms change	Your waiting-period clock keeps running toward the moratorium
GST is 18% (employer plans are not exempt)	GST is 0% since Sept 2025
You have no control over the policy terms	You choose sum insured, insurer, and features

The worst possible timing for a gap in cover is right after you lose or change a job, which is precisely when your group cover disappears. An individual policy in your own name means your protection never depends on your employment status. Think of the group cover as a bonus layer on top of your own policy, not a replacement for it.

Core rule: your employer's health cover is a perk that can vanish in one HR email. Your own policy cannot.

11. Is a family floater or an individual policy better?

Factor	Individual policy	Family floater
Sum insured	Dedicated to one person	Shared across all members
Premium	Lower per person, adds up for a family	Usually cheaper combined than separate individual policies
Risk	One person's illness never affects another's cover	One large claim by one member can exhaust the shared sum insured for everyone else that year
Best for	Young singles, or when one member has high risk	Young couples/families where members are all reasonably healthy

At 28 and single, an individual policy is the simple right choice. Once you have a spouse and kids, a floater can be cost-efficient, but keep your parents on a completely separate policy from your own family floater. Parents in their 50s and 60s carry very different risk and cost profiles, and mixing them into your floater usually pushes the whole family's premium up sharply while shrinking effective cover for everyone.

12. How do you actually choose a good policy?

Ignore the premium as your first filter. Filter on these instead, in this order:

1. No room-rent capping, or as high a cap as you can get. This alone avoids an entire category of claim disputes.
2. High claim settlement ratio and high claims paid by amount, not just by number of claims. A high ratio by count can still hide a low ratio by value if the insurer settles small claims easily but fights big ones. Check the insurer's published data (IRDAI publishes an annual report with this) before buying.
3. Wide network hospital list in your city, even though Cashless Everywhere reduces how much this matters, a strong local network still means a smoother cashless experience at your usual hospitals.
4. Reasonable waiting periods, in line with or better than the regulatory maximums covered above.
5. Sub-limits on specific treatments. Some cheaper policies cap what they will pay for specific things like cataract surgery or knee replacement regardless of your overall sum insured. Avoid policies with a long list of such sub-limits.
6. Restoration benefit. A good policy restores your sum insured if it gets exhausted in a policy year, so a second unrelated illness later that year is not left uncovered.

Core rule: compare policies feature by feature, not premium by premium. The cheapest policy on the page is often the most expensive one the day you actually need it.

Which type of health cover fits your life stage?

Life stage	Recommended cover
Single, first job (like you at 28)	₹10 lakh individual policy
Married, no kids yet	₹10 to 15 lakh individual or floater
Married with kids	₹15 to 25 lakh family floater, kids added on
Parents (50s/60s)	Separate ₹15 to 25 lakh senior-focused policy
Self-employed/freelance	Individual policy is non-negotiable, no employer safety net at all

Should you buy health insurance if you already feel healthy?

Yes, and this is the exact moment to buy it. Health insurance is priced on your age and health status at purchase. The younger and healthier you are, the lower your premium, and you likely have no pre-existing conditions to wait out in the first place.

Waiting until you actually need it is the single most expensive mistake in health insurance. By the time you have a diagnosed condition, that condition becomes a pre-existing disease on any new policy, subject to the waiting period, or the insurer may load your premium, add exclusions, or reject you outright.

Putting it together: your 28-year-old self buying a ₹10 lakh policy

You compare three quotes. One has a room-rent cap and a slightly lower premium. One has no room-rent cap, a strong claim settlement ratio, and costs about ₹500 more a year, with 0% GST already reflected in the quote since you are buying after September 2025. The third bundles in a small maturity benefit and costs noticeably more.

Skip the bundled one immediately, health and investment do not belong in the same product (the life insurance guide covers exactly why). Between the first two, take the one with no room-rent cap and the better settlement ratio, even at the slightly higher premium. ₹500 a year is nothing against the risk of a proportionately slashed claim during an actual hospitalisation.

You are now covered for ₹10 lakh, your GST bill is zero, your waiting periods are running down toward the 5-year moratorium, and you can walk into any hospital in the country and go cashless within 48 hours of admission. That is a genuinely strong starting position, and it gets stronger every claim-free year through your no-claim bonus.
