What is a sub-limit in health insurance?
In shortA sub-limit is a cap on what your policy pays for a particular treatment or item, such as ₹40,000 per eye for cataract, even when your sum insured is much higher.
Sub-limits are common on cataract, joint replacement, hernia, maternity, ambulance and modern treatments like robotic surgery. Above the cap, you pay the rest.
A ₹10 lakh policy with a ₹1.5 lakh knee replacement cap pays ₹1.5 lakh for a ₹3 lakh surgery. The sum insured doesn’t change that.
| Surgery billed | ₹3,00,000 |
| Sub-limit | ₹1,50,000 |
| You pay | ₹1,50,000 |
A co-pay, if your policy has one, is taken on the ₹1.5 lakh too.

Questions people ask
Do all policies have sub-limits?
No. Many newer plans have none on common treatments; older and lower-priced plans often do.
Are sub-limits per year or per claim?
Either. The wording says “per policy year”, “per eye” or “per claim”.
General information, not advice. Your policy’s own wording decides what it pays; IRDAI figures are from its Master Circular on Health Insurance Business (May 2024).
