Top Health Insurance Companies In India, ranked by health premium collected, are New India Assurance, Star Health, Oriental Insurance, Care Health and Bajaj General. Size is not the same as service, though, and no single insurer is “best” for everyone.
Top Health Insurance Companies In India List: How the Market Is Built
Before the ranking, you need to know who is on the field. Every insurer among the top health insurance companies in India is licensed by IRDAI, but they fall into three groups.
| Group | Who | What it means for you |
|---|---|---|
| Public sector general insurers | New India Assurance, Oriental Insurance, National Insurance, United India Insurance | Sell health along with motor, fire and other covers. Strong in employer (group) policies. |
| Private general insurers | ICICI Lombard, Bajaj General, HDFC ERGO, Tata AIG, SBI General and others | Sell health plus other lines. |
| Standalone health insurers (SAHI) | Star Health, Care Health, Niva Bupa, Aditya Birla Health, ManipalCigna and newer small players | Sell only health insurance. |
As of 1 April 2026, Wikipedia (citing IRDAI’s own lists) counts 33 non-life insurers, six of them standalone health insurers. Newer entrants such as Galaxy Health and Narayana Health Insurance show up in IRDAI flash figures with shares of 0.01% or less.

Top Health Insurance Companies In India Claim Settlement and Claims Ratios
This is where most articles on the top health insurance companies in India go wrong, so read carefully.
Why one claim settlement ratio can mislead
A claim settlement ratio (CSR) is meant to show how many claims an insurer settled. But the same insurer can show very different numbers depending on how it is measured. These are CSR figures for Star Health that I found on different pages:
| Source reviewed | Star Health CSR shown | Period given |
|---|---|---|
| PolicyX top-10 table | 66.47% | 2023-24 |
| Fincover | About 82.3% | Cited as 2025 |
| CitizenNest | 90.28% | IRDAI 2023-24 |
| Kapizo | 99.06% | FY 2025-26 |
Incurred claims ratio (ICR): a second check
ICR shows how much of the premium an insurer spent on claims. According to IRDAI’s 2025-26 annual report, as reported by CAalley:
| Insurer or group | ICR, FY26 |
|---|---|
| Niva Bupa | 61.22% |
| Care Health | 64.53% |
| Standalone health insurers (combined) | 68.06% |
| Star Health | 70.30% |
| Aditya Birla Health | 71.50% |
| ManipalCigna | 74.81% |
| Public sector general insurers (combined) | 99.84% |
Neither a low nor a high ICR is automatically good. A low ratio can mean an insurer keeps more of each premium. A very high one can mean claims are heavy compared to the premiums charged, as with the public sector group. Use ICR next to the CSR, complaints and your own reading of the policy.
How to Choose Among the Top Health Insurance Companies In India
- Start with your type of cover. Family floater, individual, senior citizen or top-up each suit different people.
- Shortlist three insurers from the top health insurance companies in India, not ten. Use the retail column above as a starting point.
- Compare the plan wording, not the brand, using the table on limits.
- Check claims and complaints from IRDAI’s data, with year and method.
- Confirm cashless hospitals near your home and your parents’ home.
Avoid fake sites and false claims
- Buy only from the insurer’s own website or an IRDAI-registered intermediary. Verify the intermediary on IRDAI’s website.
- Never pay through a link sent on WhatsApp or SMS from an unknown number.
- Be wary of “No. 1 insurer” claims with no year or method.
Disclaimer: This article is general information, not financial or insurance advice. Rankings by size are not quality ratings. For year-specific plan details, read the policy wording and speak to the insurer or a registered adviser.
Key Takeaways
- Among the top health insurance companies in India, New India Assurance, Star Health and Oriental Insurance led by FY26 health premium.
- Star Health, Care Health and Niva Bupa lead the retail segment.
- Compare CSR figures only when the year and method match.
- Your rights on cashless timing, moratorium and waiting periods are set by IRDAI, whichever insurer you pick.
Frequently Asked Questions
Is a standalone health insurer safer than a general insurer among the top health insurance companies in India?
Not necessarily. I found no verified evidence that either type is safer. Compare claims data, complaints, and the plan terms for each insurer.
Can an insurer refuse renewal after I make a claim?
Under IRDAI’s 2024 Master Circular, renewal cannot be denied only because you claimed earlier, except for established fraud or misrepresentation.
What if I am unhappy with my insurer?
Raise a complaint with the insurer first, then use IRDAI’s Bima Bharosa portal. You can also port to another insurer, which should keep your waiting period credits, as summarised by Ditto.
Do the top health insurance companies in India settle claims faster because they are big?
No. Size shows how much premium an insurer collects. Speed depends on the insurer’s process and the hospital. Check the one-hour and three-hour cashless rules.
Where can I check an insurer is genuine?
Use IRDAI’s list of general and health insurers on its website. If an intermediary sells you the policy, verify its registration there too.
