Frequently Asked Questions
TATA AIG vs HDFC Ergo: Which is better?
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 known for feature-rich plans like Optima Secure, which doubles your cover from day one. At Ditto, we recommend HDFC Ergo if you want a massive network of 16,000+ hospitals and superior tech support. TATA AIG is excellent for those who want a known brand. HDFC Ergo has an excellent claim settlement ratio of over 95%, making it a reliable giant in Indian health insurance.
What are the benefits of HDFC Ergo Optima Secure Plus?
HDFC Ergo Optima Secure Plus helps your sum insured keep pace with medical inflation by doubling it over time. The plan also includes unlimited restoration of coverage within a policy year, and covers consumables and non-payable expenses through the Protect Benefit. Optima Secure Plus also offers optional add-ons such as infinite claims, chronic care benefits, maternity/IVF cover, and wellness services. Buyers can further benefit from claim-free and lifetime discounts, helping reduce overall premium costs.
Does HDFC Ergo have a better hospital network than TATA AIG?
HDFC Ergo currently has a slightly larger network, with over 16,000 hospitals compared to TATA AIG's 12,000. At Ditto, we recommend checking which one has more hospitals in your specific city. HDFC Ergo's vast network ensures you can access 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?
HDFC Ergo is a better performer than TATA AIG, with claim settlement ratios consistently hovering around 97% to 98%. Its current average CSR for FY 2023-26 is 97.61. In contrast, TATA AIG’s current average CSR is 88.94%, which is slightly lower than other insurers in the market. At Ditto, we recommend not making a decision based solely on the claim settlement ratio. Instead, look at their incurred claim ratio and complaint figures, which are better for HDFC Ergo.
Does TATA AIG health insurance cover maternity?
Yes, TATA AIG Medicare Premier covers maternity expenses ranging from ₹50,000 to ₹1.2 lakh, but only after a 3-year waiting period from the policy start date. Medicare Select also offers maternity as an optional rider. If maternity benefits are a priority, TATA AIG Medicare Premier is worth comparing directly against HDFC Ergo Optima Secure Plus. At Ditto, we usually recommend checking if your corporate health insurance already includes maternity benefits. Maternity cover involves long waiting periods, making the additional premium difficult to justify for many buyers.
Is HDFC Ergo Optima Secure Plus worth the higher premium?
HDFC Ergo Optima Secure Plus costs around ₹13,459 per year for a 25-year-old individual in Delhi for a ₹15 lakh sum insured, compared to ₹9,445 for TATA AIG Medicare Select for the same profile. The price difference is meaningful, but what you get in return is the Infinity Benefit, which adds 100% of your base sum insured every year with no upper cap, unlimited built-in restoration after every claim, and a 2X cover from day one. For buyers under 60 planning to hold the policy long term, this compounding benefit makes the higher premium worth considering.
Does HDFC Ergo settle claims in-house or through a TPA?
HDFC Ergo settles health insurance claims in-house without routing them through a Third-Party Administrator (TPA). This is generally considered an advantage because it tends to lead to faster pre-authorization decisions and more direct communication during hospitalization. Based on Ditto's experience, HDFC Ergo has been reasonably proactive on the operational front, including decent policy issuance and claim settlement timelines, which is one reason it is rated higher on overall reliability. For more details on the insurer, refer to our guide on HDFC Ergo health insurance review.
Which TATA AIG health insurance plan is best for senior citizens?
TATA AIG Elder Care is for individuals aged 61 and above and is worth considering for senior citizens who do not qualify for plans with a standard entry age cap. It covers a sum insured of ₹5 lakh to ₹25 lakh, has a reduced pre-existing disease waiting period of 2 years, and offers a 10% No Claim Bonus up to 100% of the sum insured. However, the plan has a mandatory co-payment clause of 20%, room rent limits, and disease-wise sub-limits. Given the limitations of the plan, Optima Secure Plus may be a more comprehensive option compared to Elder Care.
