Your health insurance will reject the claim you need most, unless you read page 47
Health insurance brochures show the sum insured. The policy document shows the sub-limits, co-payments, waiting periods, and exclusions that determine what you actually get. Here is how to read the parts that matter.
A ₹10 lakh health insurance policy does not mean the insurer pays ₹10 lakh when you are hospitalised. It means the insurer pays up to ₹10 lakh, minus whatever the sub-limits, co-payments, waiting periods, room rent caps, and exclusions remove.
The claim rejection rate in India is roughly 10% to 15%, according to IRDAI data. But the more common problem is not outright rejection — it is partial settlement, where the insurer pays ₹2.5 lakh on a ₹4 lakh bill and the patient covers the rest.
The five clauses that reduce your payout
1. Room rent sub-limit
Many policies cap the room rent at 1% to 2% of the sum insured. On a ₹5 lakh policy, that is ₹5,000 to ₹10,000 per day.
The trouble: room rent is not just the room. Most policies apply a proportional reduction to all associated charges — surgeon fees, anaesthetist charges, OT costs — if you exceed the room rent limit. Choose a ₹12,000 room when your cap is ₹5,000, and every other charge is reduced by 58%.
A ₹3 lakh surgery bill with a room rent breach can settle at ₹1.5 to ₹1.8 lakh. The remaining ₹1.2 to ₹1.5 lakh is your problem.
What to look for: "No room rent sub-limit" or "room rent up to single private AC room." If the policy has a cap, consider whether the cap matches actual hospital rates in your city.
2. Co-payment clause
A 10% to 20% co-payment means you pay that percentage of every claim, every time. On a ₹5 lakh claim, a 20% co-pay costs you ₹1 lakh.
Co-payments are common in policies for senior citizens, policies with lower premiums, and policies covering pre-existing diseases. They are sometimes buried in the fine print rather than highlighted at purchase.
What to look for: "Zero co-payment." If co-pay exists, understand whether it applies to all claims or only specific conditions.
3. Waiting periods
- Initial waiting period: 30 days. No claims at all except for accidents.
- Specific disease waiting period: 2 to 4 years for conditions like hernia, kidney stones, cataracts, joint replacements, and sinusitis.
- Pre-existing disease waiting period: 2 to 4 years, sometimes with a co-pay even after the waiting period ends.
A person who buys a policy and discovers they need a knee replacement six months later is not covered. The waiting period is the insurer's protection against people who buy insurance because they already need it.
What to look for: Shorter waiting periods (2 years vs 4 years). Some policies offer buy-down options — pay a higher premium to reduce the waiting period.
4. Disease-specific sub-limits
Some policies cap specific treatments at a percentage of the sum insured. Cataract surgery capped at ₹40,000 on a ₹10 lakh policy. Maternity capped at ₹50,000 when the actual cost is ₹1.5 to ₹3 lakh.
These sub-limits mean your ₹10 lakh policy is not ₹10 lakh for everything — it is ₹10 lakh for a heart surgery but ₹40,000 for cataracts. The sum insured is a ceiling, not a floor.
What to look for: "No disease-specific sub-limits" or check the sub-limit schedule against the treatments you are most likely to need.
5. Excluded treatments
Every policy has an exclusion list. Common exclusions include:
- Dental treatment (unless caused by an accident)
- Cosmetic procedures
- Infertility treatment
- Congenital conditions (in some policies)
- Self-inflicted injuries
- War and nuclear events
- Alternative medicine (Ayurveda, homeopathy) — covered in some policies, excluded in others
The exclusion list is the section that determines what "health insurance" actually means for your policy. Two ₹10 lakh policies from different insurers can have entirely different exclusion lists.
The claim process that matters as much as the policy
Cashless vs reimbursement. Cashless treatment — where the insurer pays the hospital directly — is available only at network hospitals. If you go to a non-network hospital, you pay the full bill and file for reimbursement, which takes 15 to 45 days and has a higher rejection rate.
Pre-authorisation for planned procedures. Cashless claims require pre-authorisation. Submit it 48 to 72 hours before admission. Last-minute submissions are rejected more often, not because the claim is invalid, but because the insurer's desk did not have time to process it.
Document everything. The single most common reason for partial rejection is missing or inconsistent documentation. Keep every discharge summary, every prescription, every diagnostic report, every bill — original, not photocopy.
How much cover is enough
The formula most advisors use:
Sum insured = family size × ₹10 to ₹15 lakh, with a super top-up for catastrophic coverage.
A family of four: ₹15 to ₹20 lakh base policy, plus a ₹50 lakh super top-up with a ₹15 to ₹20 lakh deductible. The super top-up kicks in after the base policy is exhausted, and costs 20% to 30% of what a standalone ₹50 lakh policy would.
Review the policy annually. Hospital costs inflate at 10% to 14% a year. A ₹10 lakh cover that felt generous in 2022 is tight by 2026 and inadequate by 2030.
What the emergency fund covers when insurance does not
The gap between what insurance pays and what the hospital charges — room rent breaches, co-payments, non-covered consumables, attendant charges — comes from the emergency fund. Size the fund knowing that a hospitalisation event typically costs ₹50,000 to ₹2 lakh out of pocket even with insurance.
