How to Choose a Health Insurance Plan
Network hospitals, room rent, waiting period comparison.
Mathi had six browser tabs open. Six health insurance plans, each with its own PDF, its own table of benefits, its own list of exclusions formatted in 8-point font that seemed specifically designed to make human eyes stop working.
She had spent three weekends on this. She had a spreadsheet. She had notes. She had highlighted three different things in three different colors before realizing she did not have a system for what the colors meant.
Plan A looked great until she read the room rent clause. Plan B had no room rent limit but the hospital network in Chennai was thin. Plan C was the cheapest but the claim settlement ratio on IRDAI's website was... not great. Plan D had an OPD cover she did not need. Plan E was recommended by her CA friend who also sold LIC policies, so. Plan F was the most expensive and Mathi had no idea why.
She closed all the tabs. Made chai. Opened a fresh tab with a blank spreadsheet and decided to do this methodically.
The Framework: Five Questions, One Decision
The sum insured is the maximum amount your health insurance company will pay for claims in one policy year. It resets every year at renewal. If you spend more than this on treatment, you pay the excess.
Before comparing plans, Mathi needed to answer five questions:
- How much sum insured do I actually need?
- Which network hospitals matter to me specifically?
- What waiting periods can I live with?
- Are there any sub-limits that could bite me?
- Does the claim settlement track record hold up?
Everything else, OPD cover, restoration, NCB, is secondary. Get these five right first.
Question 1: How Much Sum Insured?
The answer depends on two things: your city and your hospital preference.
A three-day general ward stay (non-ICU) at a mid-tier private hospital:
- Chennai/Bengaluru/Hyderabad: Rs 80,000 to 1,50,000
- Mumbai/Delhi: Rs 1,20,000 to 2,50,000
- Tier 2 city: Rs 40,000 to 80,000
A single cardiac procedure (stent placement): Rs 2 to 6 lakh. Cancer treatment (one year): Rs 10 to 30 lakh. Orthopaedic surgery (knee replacement): Rs 2 to 4 lakh.
| Sum Insured | Covers | Misses | Right For |
|---|---|---|---|
| Rs 3 lakh | Minor surgeries, short hospitalisation | Cardiac, ortho, cancer | Top-up base only (employer policy) |
| Rs 5 lakh | Most general hospitalisations | Major surgeries, extended stays | Young adults in Tier 2 cities |
| Rs 10 lakh | Most scenarios in metro hospitals | Extended cancer treatment | Metro freelancers and self-employed |
| Rs 15-20 lakh | Near-comprehensive for most conditions | Multi-year cancer treatment | Higher income, older adults, family floaters |
For Mathi in Chennai at 28: Rs 10 lakh is the right number. Rs 5 lakh is insufficient for a metro. Rs 15 lakh is excellent but expensive, she can upgrade at renewal after a few years.
Instead of buying a Rs 20 lakh policy (expensive), buy a Rs 10 lakh individual plan plus a Rs 20 lakh super top-up with Rs 10 lakh deductible. The super top-up only kicks in after Rs 10 lakh is exhausted in a year. Total effective cover: Rs 30 lakh. Total cost: roughly Rs 13,000 (base) plus Rs 5,000 (super top-up) = Rs 18,000/year vs Rs 25,000 to 35,000 for a standalone Rs 20L plan.
Question 2: Network Hospitals: Don't Trust the Count
Insurers love to advertise "15,000+ network hospitals." But what matters is whether your hospitals are on the network.
Mathi's criteria:
- The hospital where her usual GP practices (Fortis Malar, Chennai)
- A government hospital she could use as backup (no insurance needed anyway)
- A specialty hospital near her studio (Apollo, Greams Road)
She went to each insurer's website and searched for her specific hospitals in her specific pin code. Results were very different from what the headline hospital count suggested.
Niva Bupa: All three on network. Star Health: Two of three (Fortis Malar not listed). Bajaj Allianz: One of three.
Niva Bupa jumped to the top of her shortlist.
An insurer's hospital network is not permanent. Hospitals get added and removed. At renewal each year, recheck whether your key hospitals are still on the network. If a hospital you rely on has been delisted, it may be worth considering switching insurers at renewal.
Question 3: Waiting Periods: The Hidden Timeline
Every health plan has multiple waiting periods. This is the period after policy start during which certain conditions are not covered.
Initial waiting period: 30 days from policy start. No claims except for accidents. All plans have this.
Pre-existing disease (PED) waiting period: 2 to 4 years from policy start. Conditions you had before buying the policy are not covered until this period ends.
Specific disease waiting period: 1 to 2 years for conditions like hernia, cataract, joint replacement, piles, regardless of whether you had them before.
Maternity waiting period: If maternity cover is included, typically 2 to 4 years waiting period before any maternity claims are covered.
The strategic implication: buy health insurance as early as possible. Every year you delay is a year of waiting period you are burning away. Mathi bought at 28. By 31 to 32, her policy will cover pre-existing conditions (if she develops any) and most specific diseases.
Scenario A: Mathi buys insurance at 28. At 31, she develops PCOS. The 3-year PED waiting period ends at 31. Her PCOS-related hospitalisation at 33 is fully covered.
Scenario B: Mathi waits until 34 to buy. At 34, she develops PCOS. The 3-year waiting period ends at 37. Any PCOS-related hospitalisation between 34 and 37 is not covered. She pays out of pocket.
The lesson: the waiting period clock only starts when you buy. Every delayed year of purchase is a delayed year of full coverage.
Question 4: Sub-Limits: Where Policies Hide the Catch
This is where most people get surprised. Sub-limits are internal caps within your policy that limit what you can claim for specific items, even if your overall sum insured has plenty left.
Room rent sub-limit: "Daily room rent capped at Rs 3,000" or "1% of sum insured per day." In a Rs 10L policy with Rs 3,000 room rent limit, if your room actually costs Rs 8,000/day, you are not just paying the Rs 5,000 difference. Many insurers proportionately reduce all associated costs (doctor visits, investigations, surgeon fee) because you chose a more expensive room.
Disease-specific sub-limits: Some policies cap cataract surgery at Rs 30,000 even if the procedure costs Rs 60,000. Or knee replacement at Rs 1.5 lakh when it costs Rs 3 lakh.
ICU sub-limits: Some policies limit ICU coverage to 2% of sum insured per day. On a Rs 5L policy, that is Rs 10,000/day. Real ICU in a private hospital: Rs 20,000 to 40,000/day.
How to check: Download the policy wording document (not the brochure). Search for the word "sub-limit" and "proportionate deduction." If you find a room rent sub-limit, either accept it or choose a plan without it.
The room rent sub-limit is the most underestimated gotcha in Indian health insurance. A policy that looks comprehensive can result in paying 40 to 60% of your actual bill out of pocket, not because your sum insured ran out, but because your room cost more than the cap. Always choose plans with no room rent sub-limit or with sub-limits linked to sum insured percentage.
Question 5: Claim Settlement Track Record
Mathi checked the IRDAI Annual Report for claim settlement ratios for health insurers. Health insurers show "incurred claims ratio" (ICR) rather than CSR.
Incurred Claims Ratio (ICR): What percentage of premiums collected were paid out as claims. An ICR of 70 to 90% is generally healthy. Below 50% suggests the insurer is very restrictive.
Top health insurers by reputation and track record (2024-25):
- Niva Bupa: ICR approx 80%, known for smooth cashless claims
- Star Health: ICR approx 75%, largest health insurer, good hospital network
- Care Health: ICR approx 85%, fast processing
- HDFC Ergo: ICR approx 72%, good for individual plans
Mathi's Comparison Matrix
After six tabs and three weekends, Mathi reduced everything to this:
| Factor | Niva Bupa | Star Health | Care Health |
|---|---|---|---|
| Sum Insured | Rs 10L | Rs 10L | Rs 10L |
| Annual Premium | Rs 15,200 | Rs 13,800 | Rs 16,400 |
| Room Rent Sub-limit | None | None | None |
| Key Hospitals Chennai | 3 of 3 on network | 2 of 3 on network | 2 of 3 on network |
| PED Waiting Period | 3 years | 2 years | 3 years |
| Day-care procedures | 586 | 400+ | 500+ |
| Restoration benefit | Yes (100%) | Yes | Yes (100%) |
| ICR 2024-25 | approx 80% | approx 75% | approx 85% |
Star Health is cheapest at Rs 13,800/year and has a 2-year PED waiting period (shorter is better). But Fortis Malar, Mathi's primary hospital, is not on the Star network. Paying Rs 1,400 less per year to lose access to her preferred hospital made no sense.
Niva Bupa it was. Rs 15,200/year. Rs 1,267/month.
The Add-Ons: What to Consider
Restoration benefit (usually included in good plans): If you exhaust your Rs 10L sum insured in one claim, restoration refills it for subsequent unrelated claims in the same year. Niva Bupa's plan restores 100%.
No-Claim Bonus (NCB): Every year without a claim, the sum insured grows, 10 to 50% per year depending on the plan, up to a cap. After 5 claim-free years, Mathi's Rs 10L could grow to Rs 15L at no extra premium.
OPD cover add-on: Covers outpatient visits, consultations, pharmacy, even dental. Costs an extra Rs 4,000 to 8,000/year. Worth evaluating only if your annual OPD spend consistently exceeds the add-on cost.
Maternity cover: 2 to 4 year waiting period. Costs Rs 3,000 to 8,000/year extra. If Mathi plans a family in the next 4 to 5 years, buying now starts the clock.
If you have a claim-free year, your NCB grows your sum insured. But if you make a small claim, say Rs 15,000, you might lose a year of NCB worth Rs 1 lakh in sum insured. Evaluate whether claiming small amounts is worth the NCB loss. Some plans offer NCB protection (one claim per year without NCB loss) for a small extra cost.
What to Do After You Buy
- Save the policy document, health card, and TPA helpline, store all three on your phone and share with a family member
- Know the cashless process: Call TPA before elective admission, not after. For emergencies, inform within 24 to 48 hours of admission.
- Track your sum insured usage: If you have made claims, know your remaining balance before the year ends.
- Review at renewal: Did your hospital stay on the network? Did any life changes (marriage, new city) warrant a review?
Key Takeaways
- Calculate your sum insured based on your city and hospital preference: Rs 10L is the metro standard for 2025
- Check network hospitals by name, not just count: the list that matters is your hospitals
- Waiting periods start from day of purchase: every delayed year of buying is a delayed year of full coverage
- Sub-limits (especially room rent) can reduce claims significantly: always choose plans without room rent sub-limits
- Read the policy wording for the word 'exclusion' before buying: brochures hide the catches
- The Rs 10L base plus Rs 20L super top-up combination gives Rs 30L effective cover at lower cost than a Rs 20L plan
Once you have chosen and bought your plan, the next critical skill is knowing how to actually use it when hospitalisation happens. Go to How to File a Health Insurance Claim, because the process is not automatic, and Mathi found that out the hard way.
A health policy has a Rs 3,000/day room rent sub-limit. Mathi stays in a Rs 8,000/day room for 3 days. Her total bill is Rs 2 lakh. What is most likely to happen?
