Health Insurers with the Highest Claim Settlement Ratio in India 2024
When comparing health insurance, most people focus on premiums and features. But there is one metric that matters more than everything else: the Claim Settlement Ratio (CSR). This tells you what percentage of claims the insurer actually paid in a given year. An insurer with 98% CSR paid 98 out of every 100 claims received. This guide presents the latest IRDAI-sourced data on CSR for all major health insurers.
What is Claim Settlement Ratio?
CSR = (Number of claims settled / Number of claims received) × 100
A higher CSR means the insurer is more likely to pay your claim when you need it. IRDAI publishes this data annually. The figures below are from the IRDAI Annual Report 2023-24.
Claim Settlement Ratios of Major Health Insurers (2023-24)
| Insurer | CSR (%) | Rating |
|---|---|---|
| Aditya Birla Health Insurance | 95.8% | Excellent |
| Care Health Insurance | 95.5% | Excellent |
| HDFC Ergo Health Insurance | 95.2% | Excellent |
| Bajaj Allianz General Insurance | 94.2% | Very Good |
| Niva Bupa Health Insurance | 91.4% | Good |
| Star Health Insurance | 90.6% | Good |
| ICICI Lombard General Insurance | 85.4% | Average |
How to Interpret CSR Data
A few important caveats when reading CSR data:
- High volumes can skew numbers: Star Health processes India's highest volume of health claims. A 90% CSR on 5 million claims represents a different operational reality than 95% on 500,000 claims.
- Rejected vs repudiated: Some claims are rejected for legitimate reasons (fraudulent claims, policy exclusions). A 95% CSR doesn't mean the remaining 5% were unfairly denied.
- Claim amount settlement: CSR measures number of claims settled, not the proportion of claim value paid. Look at "Claims Paid to Claims Received Amount Ratio" for a fuller picture.
Other Metrics to Consider Alongside CSR
Network Hospital Count
More network hospitals = more cashless claim opportunities = smoother claim experience
Average Claim Settlement Time
IRDAI mandates settlement within 30 days of complete documentation. Insurers who settle in 3–7 days provide a much better experience.
Complaint Volume per 10,000 Claims
Lower complaint ratio = better customer satisfaction and fewer disputes
Best Plans by CSR Category
Aditya Birla (95.8% CSR): Best Plan
Activ Health Platinum — comprehensive coverage with wellness rewards and 2-year PED waiting period
Care Health (95.5% CSR): Best Plan

The Bottom Line
CSR above 90% is generally considered good for health insurance. Among the major standalone health insurers, Aditya Birla, Care Health and HDFC Ergo consistently maintain the highest CSR levels. When all other factors are equal between two plans, always choose the insurer with the higher claim settlement ratio — it is the closest proxy for "will they actually pay when I need it."
