How much health insurance cover do I really need?

For Tier-1 metros (Mumbai, Delhi, Bangalore, etc.) where private hospital costs are highest, a base sum insured of ₹10–15 lakh per adult is the realistic minimum, ideally topped up with a super top-up to ₹50 lakh+. For Tier-2/3 cities, ₹5–10 lakh base plus a ₹25–40 lakh super top-up works well. Family floaters need to size for the worst case — if multiple family members might claim in the same year, a shared ₹10 lakh floater isn't enough. Don't anchor on premium; anchor on the cost of an ICU admission with surgery in your city.

Should I buy from my employer's group plan or buy individual cover?

Both — never just employer cover. Employer group health insurance disappears the day you change jobs, retire, or get laid off. Pre-existing diseases also re-trigger waiting periods if you switch from group to individual cover later (you lose continuity). Buy individual cover when you're young and healthy — premiums are low, no exclusions, and you build claim-free renewal benefits over time. Treat employer cover as a bonus, not your primary protection.

What's the difference between base policy and super top-up?

A base policy pays for any covered hospitalisation up to the sum insured. A super top-up pays only when annual claims cross a 'deductible' threshold (e.g., ₹5 lakh), and then pays up to its own large sum insured (e.g., ₹50 lakh). Super top-ups are dramatically cheaper than equivalent base cover because they only kick in for major events — exactly when you need real money. The combination of a modest base + large super top-up is the most cost-effective way to get high total coverage.

What's a room rent sub-limit and why does it matter so much?

Many older policies cap the daily room rent at 1% of sum insured (so ₹5,000/day on a ₹5 lakh policy). If you choose a hospital room costing ₹10,000/day, the insurer can either disallow the excess room rent OR proportionately reduce ALL associated costs — including doctor fees, surgery charges, and consumables — by the room-rent ratio. This 'proportionate deduction' clause can shrink a ₹3 lakh approved claim down to ₹1.5 lakh approved with no warning. Buy policies with no room rent cap or 'single private AC room' guaranteed.

Health Insurance Buying Guide India: What To Actually Look For

Health insurance is one of those purchases where the headline number — the sum insured — gets all the attention, while the clauses that actually decide whether your claim gets paid in full sit unread in the policy document. Most people figure out the gaps the hard way: at hospital discharge, when the insurer's settlement letter arrives showing 40% less than the bill.

This guide is the structured version of what to actually look for when buying health insurance in India.

Step 1: figure out your real coverage need

Anchor on the cost of a worst-case hospitalisation in your city, not on premium budgeting.

Rough benchmarks (private hospitals, 2026 prices, network rates):

Cardiac surgery (CABG, valve replacement): ₹3.5–8 lakh
Cancer treatment (annual): ₹5–25 lakh depending on type and stage
Major orthopedic surgery (hip/knee replacement): ₹2.5–5 lakh
ICU admission with ventilator (10–14 days): ₹4–12 lakh
Multi-organ failure / extended ICU: ₹15–40 lakh

A ₹5 lakh sum insured exhausts in days during a serious admission. A ₹15 lakh policy covers most major events but can be tight for cancer or extended ICU.

Rule of thumb: Total cover (base + super top-up) should equal at least 12 months of household income, never less than ₹15–25 lakh in metros.

Step 2: structure with base + super top-up

Don't buy a single ₹50 lakh base policy. The premium will be brutal, and you'll likely never use the upper levels.

Better structure:

Base policy: ₹10 lakh family floater — handles 95% of admissions
Super top-up: ₹40 lakh with ₹10 lakh deductible — kicks in for the catastrophic cases

Combined annual premium for a young couple: often ₹25,000–35,000 vs ₹65,000+ for an equivalent single base policy.

Step 3: kill the room-rent trap

This is the single most common claim-killing clause in Indian health insurance.

Old/cheap policies cap room rent at 1% of sum insured per day. If you choose a higher-category room, the insurer applies "proportionate deduction" to the entire claim — every doctor visit, every test, every medicine — in the same ratio.

What to insist on:

Policies with no room rent cap, OR
Policies guaranteeing a "single private AC room" category at any network hospital, OR
Policies that explicitly state "no proportionate deduction"

This single clause is worth more than 0.5% in premium savings.

Step 4: read the sub-limits

Many policies cap specific procedures even if your overall sum insured is much higher:

Cataract surgery: capped at ₹40,000–60,000 per eye
Knee/hip replacement: capped at ₹2–3 lakh even with ₹10 lakh sum insured
Specific procedures (hernia, appendix, gallbladder): capped lower than actual hospital charges
Maternity (where covered): capped at ₹50,000–1,00,000

Ideal policies have zero sub-limits or only sub-limits well above realistic costs.

Step 5: understand waiting periods

Three categories of waiting:

Initial waiting period: 30 days from policy start, during which only accident-related hospitalisation is covered. Universal — can't be avoided.

Pre-existing disease (PED) waiting period: 24–48 months for diseases you had at policy purchase (diabetes, hypertension, thyroid, etc.). Some insurers offer 12-month PED waiting at premium (cost more, useful if you have known conditions).

Specific disease waiting period: 1–2 years for cataract, hernia, joint replacement, kidney stones, fibroids, etc. — even if you don't have them currently.

When porting from one insurer to another, your accumulated waiting period transfers. When switching from group to individual cover, waiting periods restart.

Step 6: check co-pay and disease loading

Co-pay: percentage of claim you pay yourself. Common:

10–20% mandatory co-pay on senior citizen plans
20% co-pay on all claims for certain "low premium" plans

A 20% co-pay turns a ₹5 lakh claim into ₹4 lakh approved + ₹1 lakh out-of-pocket. Avoid mandatory co-pay unless premium savings genuinely justify it.

Disease loading: insurer adds extra premium for conditions discovered at proposal stage (diabetes, hypertension, obesity, etc.). Usually 25–100% premium loading on PED conditions. Always disclose — non-disclosure is the easiest way for insurers to deny claims later.

Step 7: network hospitals and cashless

Verify two things:

Network coverage in your city — check the insurer's hospital list. The 3–5 best hospitals near you should be on it. A policy with great features but no good network hospitals locally is useless during an emergency.
Cashless settlement track record — check IRDAI's annual Claim Settlement Ratio (CSR). Top public-sector and large private insurers settle 90%+ of claims; some smaller players settle 70–80% with longer dispute timelines.

Step 8: features that actually matter

Look for these in modern policies:

No-claim bonus (NCB): cumulative bonus on sum insured for claim-free years. Good plans give 50–100% NCB after 5 years.
Restoration benefit: sum insured automatically restores after exhaustion within the year — useful for repeat claims.
Day-care procedures covered — many surgeries no longer require 24-hour admission.
Pre- and post-hospitalisation expenses — typically 30/60 days pre and 60/90 days post.
AYUSH coverage — Ayurveda, Yoga, Unani, Siddha, Homeopathy treatment in registered facilities.
Domiciliary treatment — when hospital admission isn't possible.
Ambulance charges (modest sum but useful).

Step 9: avoid common scams and mis-selling

"Combo plans" with savings/investment components mixed in — almost always bad value. Buy term life + pure health insurance separately.
Single premium "lifetime" policies — flexibility loss, often poor value vs annual renewals.
Overly cheap online plans with fine print exclusions for everything that actually happens.
Policies bundled with credit cards or bank loans — usually low cover, high exclusions.
Group "lifetime" cover from your bank/employer — disappears when relationship ends.

Step 10: tax benefit (a nice-to-have, not the reason)

Section 80D allows deduction:

₹25,000 for self/spouse/children health insurance premiums
Additional ₹25,000 for parents (₹50,000 if parents are senior citizens)
Plus ₹5,000 for preventive health check-ups (within above limits)

Worth claiming, but the tax saving is tiny compared to the actual protection value. Buy the right cover first; tax is a bonus.

When to buy and review

Buy before age 35 if possible — premiums are dramatically lower and you build claim-free history.
Review every 2–3 years for: hospital network changes, life events (marriage, kids, parent dependency), and inflation in healthcare costs.
Increase sum insured every 5 years to keep up with healthcare inflation (~10% per year).
Don't lapse the policy — gap of even 30 days resets all waiting periods.

Health insurance is one of those purchases where the cheap option becomes the most expensive choice at the worst possible time. Spend the extra hour reading the policy wording, paying for the right structure, and understanding the room-rent and sub-limit clauses. It's the kind of preparation you won't appreciate until you need it — at which point appreciating it is too late.
