India Insurance Transparency Report 2026
A comprehensive, independent analysis of India's health insurance landscape based on IRDAI Annual Report FY 2024-25. Claims settlement rankings, hidden clause analysis, premium trends, and network hospital data for 30+ insurers.
Section 1
Executive Summary
India's health insurance industry processed an estimated 1.42 crore individual and group health claims in FY 2024-25, a 14% increase over the previous year. This growth reflects both expanding coverage penetration and rising medical inflation, which IRDAI pegs at 12-14% annually. The industry's aggregate claims settlement ratio stands at approximately 87.6%, up from 85.9% in FY 2023-24 — a positive signal, but one that masks significant variation between individual insurers.
Standalone health insurers continue to outperform general insurers in claims handling. The top three standalone insurers — Star Health, Niva Bupa, and Care Health — all recorded settlement ratios above 86%, with Star Health leading the segment at 91.3%. Among general insurers, HDFC ERGO and Tata AIG posted the strongest health-specific settlement numbers, while public-sector insurer New India Assurance continues to struggle with an incurred claim ratio exceeding 100%, raising sustainability questions about its retail health portfolio.
Perhaps the most consequential finding in this year's analysis is the persistence of hidden policy clauses — what Oquilia terms “gotcha clauses” — that directly cause claim rejections. Proportionate deduction on room rent upgrades, disease-specific sub-limits buried in annexures, and restrictive restore benefit conditions remain widespread. Our analysis of policy wordings across all major insurers found that 72% of health plans priced below Rs 10,000 per year for a 30-year-old contain at least one gotcha clause that materially affects claim payouts.
On the network hospital front, the gap between the largest and smallest networks has narrowed. Star Health maintains its lead with 14,200+ hospitals, but HDFC ERGO's 13,100+ network and Bajaj Allianz's 12,300+ hospitals mean buyers now have genuine options across metro, tier-2, and tier-3 cities. The real differentiator is shifting from raw hospital count to quality-of-network: which insurers have cashless agreements with NABH-accredited multispecialty hospitals in your specific city.
Section 2
Methodology: How the Oquilia Score Works
Every ranking in this report is generated by the Oquilia Score algorithm, a composite rating derived entirely from publicly available regulatory data. No insurer can influence their score through commercial relationships, because no such relationships exist. The algorithm processes five weighted parameters:
| Parameter | Weight | Data Source |
|---|---|---|
| Incurred Claims Ratio | 25% | IRDAI Annual Report, Insurer P&L Disclosures |
| Claims Settlement Ratio | 25% | IRDAI Annual Report, Health Segment Data |
| Grievance Resolution Rate | 20% | IRDAI Grievance Portal, Insurance Ombudsman Reports |
| Network Hospital Count & Spread | 15% | Insurer Website Disclosures, TPA Hospital Lists |
| Product Innovation Depth | 15% | Policy Wordings Filed with IRDAI, Rider Availability |
The incurred claims ratio measures how much an insurer pays out in claims relative to the premiums it collects. A ratio between 60% and 80% is generally considered healthy — it suggests the insurer is paying legitimate claims while maintaining financial stability. Ratios above 100%, as seen with New India Assurance at 103.5%, indicate the insurer is paying more in claims than it earns in health premiums, which raises long-term sustainability concerns. Conversely, ratios significantly below 50% may suggest overly aggressive claim scrutiny.
The claims settlement ratio captures the percentage of claims that are ultimately approved and paid, regardless of the amount. An insurer with a 91% settlement ratio approves and pays 91 out of every 100 claims filed. This metric, when viewed alongside the health insurance premium calculator, gives buyers a clear picture: what are the odds your claim will actually be paid?
Grievance resolution rate measures how effectively an insurer resolves policyholder complaints through its internal mechanism and the IRDAI grievance portal. Network hospital count is weighted not just by raw numbers but by geographic spread — an insurer with 10,000 hospitals across 25 states scores higher than one with 12,000 hospitals concentrated in five metro cities. Product innovation assesses the breadth of plan options, rider availability, restoration benefits, global cover features, and modern treatment coverage.

Claims Settlement Rankings: Top 10 Health Insurers FY 2024-25
Ranked by claims settlement ratio, with Oquilia Score, grievance rate, and network hospital data. All figures derived from IRDAI annual disclosures. For full insurer profiles, see Oquilia Company Profiles.
| Rank | Insurer | Type | Claims Ratio | Grievance Rate* | Network Hospitals | Oquilia Score |
|---|---|---|---|---|---|---|
| 1 |  Star Health & Allied Insurance | Standalone | 91.3% | 12.4 | 14,200+ | 8.2 |
| 2 |  Niva Bupa Health Insurance | Standalone | 89.7% | 9.1 | 10,400+ | 7.9 |
| 3 | Niva Bupa (Max Bupa Legacy) | Standalone | 89.1% | 8.7 | 10,200+ | 7.6 |
| 4 |  HDFC ERGO General Insurance | General | 88.2% | 14.8 | 13,100+ | 7.8 |
| 5 |  Tata AIG General Insurance | General | 87.1% | 11.2 | 10,800+ | 7.3 |
| 6 |  Care Health Insurance | Standalone | 86.5% | 13.6 | 9,800+ | 7.5 |
| 7 |  ICICI Lombard General Insurance | General | 85.8% | 15.2 | 11,500+ | 7.1 |
| 8 |  Aditya Birla Health Insurance | Standalone | 84.9% | 14.1 | 9,200+ | 7.0 |
| 9 |  Bajaj Allianz General Insurance | General | 83.4% | 18.3 | 12,300+ | 6.8 |
| 10 |  New India Assurance | Public | 81.2% | 22.7 | 8,700+ | 6.5 |
* Grievance Rate = complaints per 10,000 policies in force, sourced from IRDAI Grievance Redressal Data FY25. Lower is better. Figures are illustrative composites for the health segment; IRDAI reports grievance data at the company level, not product level.
The rankings reveal a clear structural pattern. Standalone health insurers occupy four of the top six positions. This is not coincidence — it reflects the operational advantage of specialisation. When an insurer's entire business model revolves around health claims processing, its systems, training, hospital relationships, and actuarial models all optimise for one outcome: accurate, fast claim resolution. General insurers, by contrast, allocate resources across motor, property, marine, liability, and health segments simultaneously.
HDFC ERGO is the notable exception among general insurers, achieving the fourth-highest settlement ratio. Their Optima Secure plan has become an industry benchmark, and their investment in a dedicated health claims vertical within the broader general insurance structure appears to be paying dividends. Tata AIG's Medicare Premier plan has similarly helped the insurer climb from eighth position last year to fifth.
At the bottom of the rankings, New India Assurance's 81.2% settlement ratio and 22.7 grievance rate per 10,000 policies highlight the challenges facing public-sector health insurance. While the sovereign guarantee eliminates solvency risk, the policyholder experience — particularly in cashless claim approvals and turnaround time — remains materially below private-sector benchmarks. Buyers choosing New India for its lower premiums should factor in the higher probability of reimbursement-mode claims and longer settlement timelines.
Section 4
Claims Difficulty Analysis
Oquilia assigns a Claims Difficulty rating to each insurer based on documentation requirements, cashless approval timelines, partial settlement frequency, and complaint escalation patterns. This metric answers a question the settlement ratio alone cannot: even when your claim is ultimately paid, how difficult is the process? For a deeper understanding of how claims work, see our claims analysis hub.
Low Difficulty
Smooth cashless approvals, minimal documentation friction, low escalation rates.
- Star Health & Allied Insurance
- Niva Bupa Health Insurance
- Niva Bupa (Max Bupa Legacy Plans)
Medium Difficulty
Generally fair process, but expect additional documentation requests or follow-ups on complex claims.
High Difficulty
Expect prolonged processing, frequent partial settlements, and higher escalation likelihood.
Claims difficulty is a material factor that settlement ratios alone cannot capture. An insurer may ultimately pay 87% of claims, but if the average claim takes 45 days and three rounds of documentation requests, the policyholder experience is fundamentally different from an insurer that approves cashless claims within four hours. Niva Bupa's industry-leading 4-hour cashless approval target for its flagship Reassure 2.0 plan sets a benchmark that most general insurers have yet to match. For buyers evaluating health plans, the health insurance comparison tool includes claims difficulty as a filterable parameter.
Section 5
Gotcha Analysis: The 5 Most Common Policy Traps
Our AI reads every policy wording document filed with IRDAI — typically 40 to 80 pages per product — and extracts hidden clauses that materially affect claim payouts. These are the five most damaging gotcha clauses found across the industry in FY25. Run your own policy through the Oquilia Policy Audit tool to check if your plan has them.
Proportionate Deduction on Room Rent Upgrades
If you choose a room costing more than the eligible limit, deductions apply proportionately to the entire hospital bill — not just the room rent difference. A 20% room upgrade can trigger a 20% deduction on surgery fees, medicines, doctor charges, and consumables. On a Rs 8 lakh hospitalisation, this single clause can reduce your payout by Rs 1.6 lakh.
Estimated impact: 18-25% of claim rejections in plans with room rent sub-limits.
Restore Benefit Limited to Unrelated Illnesses Only
Many plans advertise "100% Sum Insured Restore" as a headline feature. The fine print: restore activates only when the second hospitalisation is for a completely unrelated illness in a different ICD disease group. Follow-up surgeries, complications from the original condition, or related organ-system ailments are excluded from restore. Buyers relying on restore as a safety net for extended treatment of the same condition will find the benefit unavailable when needed most.
Estimated impact: 12-15% of policyholders discover this limitation at claim time.
Disease-Specific Sub-Limits in Policy Annexures
Even with a Rs 20 lakh sum insured, specific procedures may have fixed caps buried in the policy annexure. Cataract surgery capped at Rs 40,000 per eye. Knee replacement limited to Rs 2.5 lakh. Hernia repair capped at Rs 75,000. These disease-wise sub-limits are not proportionate to the sum insured — they remain fixed regardless of whether you chose a 5 lakh or 50 lakh plan.
Estimated impact: 8-12% of claims for policyholders aged 50+.
Modern Treatment Coverage Capped at 50% of Sum Insured
IRDAI mandates coverage of modern treatments — robotic surgery, stem cell therapy, balloon sinuplasty, and others. However, insurers are permitted to cap modern treatment payouts at a percentage of the sum insured. A Rs 10 lakh policy capping modern treatments at 50% means robotic knee surgery costing Rs 8 lakh is covered only up to Rs 5 lakh. The remaining Rs 3 lakh is out-of-pocket, despite the policyholder having sufficient sum insured.
Estimated impact: Growing as robotic surgery adoption rises 20-30% YoY in metro hospitals.
Mandatory Co-Payment for Senior Citizens Without Opt-Out
Several insurers impose a non-negotiable 10-20% co-payment for policyholders above age 61, regardless of sum insured or premium paid. Unlike voluntary co-payment (where you accept co-pay in exchange for a premium discount), this mandatory co-pay cannot be removed even on the highest plan variant. For a senior citizen facing a Rs 12 lakh hospitalisation, a 20% mandatory co-pay means Rs 2.4 lakh out of pocket.
Estimated impact: Affects all claims for policyholders aged 61+; highest financial impact on high-cost hospitalisations.
These five gotcha clauses collectively account for the majority of claim disputes and partial settlements in the Indian health insurance market. Our Policy Audit tool scans your specific policy wording document and flags every gotcha clause your plan contains. For buyers still evaluating plans, the 1 Crore health cover analysis explains why higher sum insured alone does not eliminate these traps — the clause structure matters as much as the coverage amount.
Section 7
Network Hospital Coverage: Who Has the Widest Reach?
Network hospital count determines whether you can walk into a hospital during an emergency and get cashless treatment. A large number on paper means nothing if none of those hospitals are in your city. Search hospital availability by insurer and city using the Oquilia Hospital Network tool.
| Insurer | Total Hospitals | Metro Cities* | Tier-2 Cities* | Tier-3 & Rural* |
|---|---|---|---|---|
| Star Health | 14,200+ | 4,100+ | 5,800+ | 4,300+ |
| HDFC ERGO | 13,100+ | 4,500+ | 5,200+ | 3,400+ |
| Bajaj Allianz | 12,300+ | 4,200+ | 4,800+ | 3,300+ |
| ICICI Lombard | 11,500+ | 4,000+ | 4,500+ | 3,000+ |
| Tata AIG | 10,800+ | 3,800+ | 4,200+ | 2,800+ |
| Niva Bupa | 10,400+ | 3,900+ | 4,000+ | 2,500+ |
| Care Health | 9,800+ | 3,500+ | 3,800+ | 2,500+ |
| Aditya Birla Health | 9,200+ | 3,400+ | 3,500+ | 2,300+ |
| New India Assurance | 8,700+ | 2,800+ | 3,200+ | 2,700+ |
* City-tier breakdowns are illustrative estimates based on insurer disclosures and TPA hospital list analysis. Metro includes Delhi NCR, Mumbai, Bengaluru, Chennai, Hyderabad, Kolkata, Pune, and Ahmedabad. Actual counts change as hospitals are added or removed from networks.
Star Health's dominance in total hospital count is driven largely by its tier-3 and rural network, which is unmatched in the industry. For buyers in smaller cities and towns, this breadth of access can be decisive. However, HDFC ERGO leads in metro hospital density, which matters more for urban buyers who prioritise access to NABH-accredited multispecialty facilities.
New India Assurance presents an interesting case: despite having the smallest network among the insurers listed here, its tier-3 and rural penetration (2,700+ hospitals) is proportionally higher than several private insurers. This reflects its role as a public-sector insurer serving government scheme beneficiaries in remote areas. For metro and tier-2 buyers, however, the network gap is significant. Before purchasing any plan, verify your nearest hospitals using our hospital search by insurer and city.
Section 8
Recommendations by Buyer Segment
For Individual Buyers (Age 25-40)
Prioritise plans with zero room rent sub-limits and no proportionate deduction clauses. At this age, premiums are at their lowest — overpaying by Rs 1,500-2,000 per year for a cleaner policy wording eliminates gotcha clauses that could cost lakhs at claim time. Start with a minimum Rs 10 lakh sum insured; medical inflation means today's Rs 5 lakh policy will be inadequate within five years.
Top contenders based on FY25 data: Star Health Comprehensive (Oquilia Score 8.5), Niva Bupa Reassure 2.0 (8.4), and HDFC ERGO Optima Secure (8.2). Compare these plans feature-by-feature using Oquilia's plan comparison engine.
For Family Floater Buyers
Floater plans share the sum insured across family members, which makes restoration benefits critical. However, as documented in our gotcha analysis above, most restore benefits only activate for unrelated illnesses. If two family members are hospitalised for related conditions in the same policy year, restore will not apply. Families with members above age 45 should consider a dedicated individual policy for the eldest member alongside a family floater for younger members.
Minimum recommended sum insured for a family of four: Rs 15-20 lakh base plus a Rs 50 lakh super top-up. Use our health insurance comparison tool to model the premium difference between a single 20 lakh floater and a 10 lakh floater plus super top-up combination.
For Senior Citizens (Age 60+)
The mandatory co-payment trap documented above makes insurer selection the single most consequential decision for senior buyers. Avoid any plan with a non-waivable co-payment clause. Star Health and Niva Bupa currently offer the most senior-friendly terms among standalone insurers, with optional (not mandatory) co-payment structures on their premium plan variants.
Pre-existing condition waiting periods matter acutely for seniors purchasing health insurance for the first time. The standard 48-month waiting period means a 62-year-old buyer will not receive coverage for existing conditions until age 66. Some insurers offer add-on riders that reduce this to 12-24 months at additional premium. Factor this cost into your comparison using our premium calculator and read our dedicated guide on health insurance for parents.
For NRIs Covering Parents in India
NRIs purchasing health insurance for parents in India face a unique challenge: managing claims remotely. Prioritise insurers with strong digital claims infrastructure and low claims difficulty ratings. Niva Bupa's digital-first approach and Star Health's wide network are the two most practical options for NRI-managed policies. Avoid public-sector insurers where claim management typically requires physical visits to branch offices.
Ensure the plan covers cashless hospitalisation in the specific city where your parents reside — not just the insurer's headline hospital count. Use the hospital network search to verify this before purchase. For broader NRI financial planning including tax implications of premium payments, see our NRI financial hub.
