HDFC Ergo Health Insurance or TATA AIG Health Insurance: Which is Better?

Founded in 2002 as a joint venture between HDFC and ERGO International AG, HDFC Ergo has become one of India's largest health insurers. Despite slightly higher costs, its comprehensive policies and extensive network of cashless hospitals contribute to its reputation as one of the country's most credible health insurance providers.

Established in 2001 through a partnership between Tata Group and American International Group, TATA AIG has rapidly grown in the industry, garnering substantial praise. While its health insurance plans may be relatively expensive with no distinctive features, some policies provide coverage for international treatments and maternity-related expenses.

Since both insurers have a couple of drawbacks that you need to consider, this will be an interesting comparison. While we have summarised the standpoint of these two general insurance providers as health insurers, a data-based comparison will be a better way to go. As far as data are concerned, we have gathered 3 years' worth of information (2020 to 2023) to get a consistent insight into the overall performance of the insurers.

Claim Settlement Ratio (CSR)

Claim Settlement Ratio is one of the most well-known metrics when determining the credibility of a health insurance provider. It is computed by finding the % between the total number of claims settled by an insurer over a year and the total number of claims filed to the insurer over the same year.

While this gives you a partial idea about the claim settlement efficiency of the insurer, what CSR fails to reflect is how fast the claims are settled and to what extent. However, it’s still a start.

So, here is an insight into the CSR of HDFC Ergo health insurance vs TATA AIG health insurance for 2022 to 2025.

CSR across the yearsHDFC Ergo Health InsuranceTATA AIG Health InsuranceIndustry Average
FY 2022-2395.49%88.65%91.50%
FY 2023-2497.19%90.88%91.18%
FY 2024-2597.45%86.63%91.20%
Average of 3 years (FY 2022-25)96.71%88.72%91.22%

CONCLUSION: HDFC Ergo takes the win here with a close-to-perfect CSR. On the other hand, since we recommend that you follow through with insurers with a 90+ score in CSR, we can safely say that TATA AIG is just a little behind!

Incurred Claim Ratio (ICR)

Where CSR falls short of reflecting how well the claims have been settled, Incurred Claim Ratio fills in the gap. ICR is calculated by drawing a % between the total amount involved in claim settlement for an insurer across a year and the total premium collected by the insurer in the same year.

The ICR of an insurer is particularly effective if you want to draw insight into the financial stability and long-term financial potential of the insurer to settle claims. The extremes of ICR reflect either

    • the insurer is too focused on making profits and thus neglecting valid claims raised by the clients or
    • if the provider is settling too much in claims and steadily losing their financial foothold, therefore heading towards an unstable business situation.

The ideal range of ICRs for health insurance providers would be between 50 to 70 or slightly higher.

Here’s how the ICRs are for HDFC Ergo and TATA AIG health insurance from 2022 to 2025:

ICR across the yearsHDFC Ergo Health InsuranceTATA AIG Health InsuranceIndustry Average
FY 2022-2379.04%78.33%79.94%
FY 2023-2480.98%77.94%81.33%
FY 2024-2584.85%76.24%84.38%
Average of 3 years (FY 2022-25)81.62%77.50%81.88%

CONCLUSION: TATA AIG is the closest to the ideal range of ICRs and, hence, takes the win. However, even though HDFC Ergo has a slightly higher ICR, it indicates that the insurer prioritises meeting its client requirements, which is good news for policyholders.

Volume of Complaints

TATA AIG and HDFC Ergo both have excellent reputations as health insurance providers. Their plans are generally comprehensive and cater to a vast pool of policyholders. However, as potential policyholders, you need to prioritise knowing whether such reputations are well-founded or not, that is, what kind of complaint records these insurers are looking at.

This will help you understand the overall operational efficiency of the insurer, its issues with overall claim settlement (since that is one of the most common reasons for complaints), etc.

Here is a look at the complaint volume for HDFC Ergo and TATA AIG for 2022 to 2025:

Complaint Volume across the yearsHDFC Ergo Health InsuranceTATA AIG Health InsuranceIndustry Average/year
FY 2022-236.2310.0818.94
FY 2023-246.8912.1128.99
FY 2024-2514.729.7531.09
Average of 3 years (FY 2022-25)9.2810.6527.06

CONCLUSION: With one of the lowest complaint volume numbers in the industry, HDFC Ergo steals the win from TATA AIG. However, the complaint volume for TATA AIG is appreciable, too. Such low numbers are good indicators for both the providers showcasing their efficiency in meeting client requirements.

Network Hospitals

The number of network hospitals for health insurance providers reflects their established reputation with medical facilities and ensures that you have convenient access to cashless treatment perks. This makes it a determining factor when choosing a health insurance provider. The more the number of partner hospitals, the higher your chances of having access to cashless treatments for scheduled and emergency medical attention.

Here is a look at the network of partner hospitals for both TATA AIG and HDFC Ergo health insurance providers -

CONCLUSION: TATA AIG health insurance wins with a close to 700 margin on HDFC Ergo. This score is impressive considering that TATA AIG has only a 1-year advantage over HDFC.

Frequently Asked Questions

Which Is Better Tata AIG Or HDFC Ergo?

 Choosing between Tata AIG and HDFC Ergo depends on your specific needs: Tata AIG is often praised for its Medicare range and global coverage, while HDFC Ergo is the leader in Optima Secure which doubles your cover from day one. At Ditto we recommend HDFC Ergo if you want a massive network of 13,000+ hospitals and superior tech support. Tata AIG is excellent for those who want a known brand. Both companies have claim settlement ratios above 95%, making them the two most reliable giants in Indian health insurance.

What Are The Benefits of HDFC Ergo Optima Secure?

The HDFC Ergo Optima Secure is famous for its secure benefit, which gives you 2x the sum insured from the very first day without any extra cost. At Ditto we recommend this for families who want a 10 lakh cover but effectively get 20 lakh protection. It also covers non-medical items like gloves, masks, and nebulizers during a claim by default. Additionally, its restore benefit refills your entire cover even if you have only partially exhausted it. This combination of features makes it one of the most comprehensive plans in the market.

Does HDFC Ergo Have A Better Hospital Network Than Tata AIG?

HDFC Ergo currently has a slightly larger network with over 13,000+ hospitals compared to Tata AIG's 10,000+ hospitals. At Ditto we recommend checking which one has more tier 1 hospitals in your specific city. HDFC Ergo's vast network ensures that you can get a cashless treatment in almost every corner of India. However, Tata AIG is very strong in certain regions and has exclusive tie ups with many top specialty clinics. Having a larger network generally makes the cashless process faster and more convenient, especially during an emergency when you can't afford to travel far.

Which Insurer Has A Better Claim Settlement Ratio?

 Both HDFC Ergo and Tata AIG are top performers with claim settlement ratios consistently hovering around 97 to 98 percent. At Ditto we recommend not making a decision based on the ratio alone, as they are both extremely reliable. Instead, look at their incurred claim ratio and complaint figures, which are better in case of HDFC Ergo.
