Frequently Asked Questions (FAQs)
Q: What is a Claim Settlement Ratio and why is it important?
A: The Claim Settlement Ratio or CSR is the percentage of health insurance claims that an insurer settled out of total claims received in a financial year. A higher CSR indicates that the insurer is more likely to honour your claim when you need it. A CSR consistently above 95 percent is considered excellent. Tata AIG at 97.07 percent, HDFC ERGO at 97.37 percent, and Care Health at 96.74 percent lead the industry in 2026.
Q: What is the size of India’s health insurance market in 2026?
A: The India health insurance market was valued at USD 15.46 billion in 2026 and is projected to grow to USD 22.86 billion by 2031 at a CAGR of 8.13 percent. The private sector dominates with a revenue share of 65.94 percent. Among standalone health insurers, Star Health is the largest with FY2025 premiums of Rs 16,716.2 crore.
Q: What is the difference between a standalone health insurer and a general insurer?
A: A Standalone Health Insurer or SAHI is a company that exclusively offers health insurance products. Examples include Star Health, Niva Bupa, Care Health, and Aditya Birla Health Insurance. A general insurer offers multiple lines of insurance including health, motor, home, travel, and commercial insurance. Examples include HDFC ERGO, ICICI Lombard, Bajaj Allianz, and Tata AIG. SAHIs tend to have deeper health insurance expertise and more specialised products.
Q: What is a cashless hospital network and how does it benefit policyholders?
A: A cashless hospital network is a group of hospitals empanelled by the insurance company where policyholders can receive treatment without paying out of pocket at the time of admission. The insurer directly settles the bill with the hospital up to the policy coverage limit. A larger cashless network means greater convenience and accessibility for the policyholder. Star Health leads with 14,000 plus hospitals while Bajaj Allianz has the largest network with 18,400 plus facilities.
Q: Does health insurance cover pre-existing diseases in India?
A: Most health insurance policies in India cover pre-existing diseases after a waiting period that typically ranges from 2 to 4 years depending on the insurer and the specific disease. After the waiting period expires, pre-existing conditions are covered like any other illness. Some insurers offer buy-back options to reduce the waiting period for an additional premium. IRDAI has also introduced standard health insurance products with more favourable pre-existing disease terms to improve consumer protection.
