When it comes to health insurance, there isn’t a single company that can be called “best” for everyone. The right choice depends on what you value most. It could be reliable claims support, strong hospital coverage, or long-term stability.
That’s why, instead of blanket rankings, we use a published Insurer Rating Methodology. Each company is first scored on six measurable parameters — Claim Settlement Ratio, Complaints, Gross Written Premium, Hospital Network, TPA model, and Online Services, which are combined into a 10-point Insurer Rating.
For simplicity, we present this rating on a 5-point scale called the Ditto Insurer Score. This keeps the comparison easy to read, while the underlying calculation remains transparent and data-driven exactly as required by IRDAI’s directives. You can read the full methodology here.
Using this framework, here are the Top 10 Health Insurance Companies in India for 2025, ranked on the Ditto Insurer Score (5-point scale):
Top 10 Health Insurance Companies in India 2025
How to Choose the Best Health Insurance Companies in India?
Picking the right insurer isn’t about flashy ads or the cheapest premium. A good company should be financially sound, settle claims fairly, and make the process simple. That’s why we developed an Insurer Rating Methodology, i.e., a transparent, data-driven approach to evaluating every insurer.
Each insurer is scored on these six measurable parameters, combined into a 10-point rating with this formula:
Insurer Rating = (0.22 x CSR Rating) + (0.17 x Network Hospitals Rating) + (0.15 x Complaints Volume Rating) + (0.25 x GWP Rating) + (0.1 x TPA Rating) + (0.1 x Online Presence Rating)

The 6 Factors Behind Our Rating
Claim Settlement Ratio (22%)
The Claim Settlement Ratio (CSR) measures the percentage of claims an insurer pays out versus the total claims received. At Ditto, we look at a 3-year average to even out any extraordinary events in any one year. A higher CSR indicates reliability in paying valid claims on time.
Complaints Volume (15%)
Complaints volume shows how many customer grievances an insurer receives, normalized per 10,000 claim volumes. The fewer the complaints, the better the claims process, generally.
Gross Written Premiums (25%)
Gross Written Premium (GWP) is the total premium an insurer collects in a year, reflecting its market scale and growth. At Ditto, we see this as a proxy for financial stability and operational maturity. A larger insurer is generally better equipped to handle high claim volumes.
Hospital Network (17%)
The hospital network represents the total number of hospitals where an insurer offers cashless claim facilities. At Ditto, we value insurers with broad networks (usually 10,000+ hospitals) since they make cashless access easier and reduce out-of-pocket expenses for policyholders.
TPA Model (10%)
The TPA model outlines the process for processing claims either in-house or through third-party administrators (TPAs). At Ditto, we generally favor in-house models, as they tend to be faster, more accountable, and aligned with the insurer’s service standards.
Online Services (10%)
This is nothing but the Digital convenience for policy purchase, renewal, and claim tracking enhances user experience and transparency.
Together, these six signals give you a clear view of who pays reliably, who keeps customers happy, and who offers strong hospital access. We then standardise the score into the Ditto Insurer Score (5-point scale) so you can compare companies at a glance while knowing the math underneath is transparent.
Company-wise Analysis of the Best Health Insurance Providers in India (2025)
Now that we’ve explained how the Insurer Score is calculated, let’s look at how the top insurers actually perform on these parameters. We’ll go one by one, breaking down what each company does well, where they fall short, and what that means for you as a customer.
This way, you’re not just seeing a rank or score, you’re also getting context on why an insurer deserves its spot and what to watch out for before choosing a plan.
HDFC ERGO - 4.95/5
HDFC ERGO stands out as one of the most dependable health insurers in India. It has built trust on the back of consistently high claim settlement performance, a huge hospital network, and strong financial backing. Customers also benefit from in-house claim servicing and a smooth digital experience — two things that make a real difference when you actually need to use the policy.
The catch? HDFC ERGO’s plans usually come at a premium. You’re paying extra for reliability and convenience, so it’s worth checking whether the higher cost makes sense for your needs when similar alternatives exist.
Key Highlights
- 96.71% claim settlement ratio (3-year average)
- 13,000+ hospitals in the cashless network
- ₹6,118 Cr in annual premiums (financially strong)
- Plans are more expensive than peers
HDFC ERGO Plans Overview
Bajaj General - 4.95/5
Bajaj General doesn’t always get the same spotlight as HDFC ERGO, but its service record is arguably even cleaner. With one of the lowest complaint ratios in the industry and consistently strong claims performance, it’s a solid choice if hassle-free claims are your top priority.
Bajaj General Overview
Bajaj General is the insurer you go to if you want smooth servicing and minimal escalation risk. But here’s the catch: as an advisor, we don’t just evaluate insurers, we evaluate products.
And Bajaj General’s product portfolio doesn’t really stand out. The plans are decent but not especially competitive on features or value, which makes it harder for us to recommend them with confidence. But these concerns are slowly being addressed. Some of their newer offerings show signs of improvement, such as more thoughtful features, clearer terms, and better alignment with customer needs.
Takeaway: Even a strong insurer can fall short if its products don’t offer the right features, because at the end of the day, what you actually buy is the policy, not just the company. That’s why Bajaj General, despite its excellent servicing record, isn’t part of Ditto’s partner list yet.
Aditya Birla Health - 4.45/5
Aditya Birla Health is one of the newer standalone players but has scaled quickly since its launch in 2016. On paper, it appears solid: a 96% claim settlement ratio, a robust 12,000+ hospital network, and a growing premium book of approximately ₹3,290 crores. The company has also built a reputation for linking insurance with wellness by offering rewards for fitness, digital health tools, and preventive-care nudges are part of its brand.
The downside? Customer experience has room for improvement. With a slightly higher complaint volume than some peers, there’s a bit of a gap between the innovation and day-to-day servicing consistency. But as the company matures, these are areas that could stabilize further.
Aditya Birla Health Pros & Cons
Takeaway: Aditya Birla Health brings energy and innovation to the table, but the service side hasn’t caught up fully yet. It’s attractive if you want wellness-linked features, but if your #1 priority is to have better claim servicing or a larger insurer, you’ll find steadier options elsewhere.

Care Health - 4.20/5
Care Health is one of the largest standalone health insurers. Its big draw is access: a very wide cashless network and strong digital plumbing, which makes it easier to find a tie-up hospital and get paperwork moving. Scale helps too. The book is sizable so day-to-day ops feel well-oiled. The trade-off is service variability: complaint rates are higher than top peers, and the claim settlement ratio slight trails the leaders though above industry averages, so experiences aren’t as consistently smooth
Care Health Overview
Who is this for?
- Buyers who prioritise cashless access across metros and tier-2/3 cities.
- Families that want wide network coverage for travel or multi-city living.
Watch-outs
- Higher complaint volume than peers → manage expectations on servicing.

Also, while the top five insurers deserved a closer look, the rest of the top 10 also have their place. They score well on our Insurer Rating and are worth knowing about, but we won’t go into the same level of detail as before. Instead, here’s a quick snapshot of what they do well, where they fall short, and the type of customer they might suit.
Niva Bupa - 4.20/5
Niva Bupa may not have the big-brand heft of HDFC ERGO or ICICI Lombard, but it more than makes up for it with product innovation. Whether it’s ReAssure 2.0, 3.0, or Aspire, Niva consistently experiments with benefits, pricing, and flexibility, often leading the market in fresh product design.
Here’s a quick overview of the company:
Niva Bupa Overview
Takeaway: Niva Bupa is a product innovator first, insurer second. Its catalogue is filled with thoughtful ideas, from unlimited reinstatements to lock-the-clock and they come at very competitive prices. But scale and complaint volume remain some of its weak spots, keeping it just below the top players, while still retaining a spot in the top 5.
In short, if you’re looking for feature-rich, value-for-money health plans, Niva Bupa often sets the benchmark. Just ensure you have the right advisory support, because with great product variety comes the need for careful plan selection.
SBI General - 3.75/5
SBI General feels like a safe, balanced option. A 96% claim settlement ratio and 16,600+ hospitals mean it’s strong on the basics. Complaints are middling (21 per 10k Claims) — not bad, but not the best either. If you want a familiar brand with wide access, SBI ticks those boxes.
Go Digit - 3.65/5
A new-age, digital-first insurer. Digit has a 99% claim settlement ratio and a wide network of 16,400+ hospitals, though its premium book is still relatively small (₹1,388 Cr). Complaints are at 17 per 10k claims, which is reasonable.
Moving forward, we would like the insurer to have a similar CSR and claims performance as they scale up. However, currently, Go Digit is best suited for buyers who are comfortable with app-first servicing and want a modern interface.
Future Generali - 3.64/5
Future Generali posts impressive metrics on paper. They have a 92% claim settlement ratio and just 11 complaints per 10k claims. But despite the strong numbers, its smaller operating scale keeps it out of the top bracket. A solid, improving insurer, but not yet in the league of the big guns.
ICICI Lombard - 3.64/5
ICICI Lombard has long been a heavyweight in general insurance. They have a large network, strong digital systems, and trusted branding. But much of the recent buzz comes from Elevate, its flagship health plan that’s been seeing growing interest for its flexibility and modern add-ons. Still, when you strip away the product appeal and focus purely on insurer metrics, the 85% claim settlement ratio remains a concern. In other words, an excellent insurer whose CSR number lets them down a bit.
TATA AIG - 3.41/5
Tata AIG is one of the oldest private sector insurers in the country. It has a claim settlement ratio of 89%, which is on the lower end of its peers. It also falls short when it comes to its product line-up. When we run plan features through our framework, Tata AIG’s policies don’t break into the top tier, so there isn’t a clear, standout recommendation from us yet. That said, newer offerings like Medicare Select are a step in the right direction.

Conclusion
There isn’t a single “best” health insurance company for everyone. Each insurer has its strengths - some excel at claim servicing, others at network coverage, and a few at product design. The right choice depends on your priorities: smoother claims, wider access, or richer features.
At Ditto, our rankings are built on a transparent, data-driven framework that uses IRDAI-mandated public disclosures - including claim settlement ratios, complaint volumes, hospital networks, gross written premiums, TPA models, and digital presence.
