What is a Sub-limit?
A sub-limit is a cap on how much your policy pays for a specific treatment or expense, even though your total sum insured is larger. For example, a cataract sub-limit of Rs 40,000 means the policy pays at most Rs 40,000 for that surgery regardless of your Rs 10 lakh cover.
How sub-limits work
Sub-limits sit inside your overall sum insured. Common ones apply to cataract, knee replacement, some other named surgeries, ambulance charges, and modern treatments. Room rent and ICU charges are also a form of sub-limit.
If the actual cost exceeds the sub-limit, you pay the excess out of pocket, even if plenty of your sum insured is unused.
Why insurers use it
Sub-limits let insurers control cost on procedures that vary widely in price or are prone to inflated billing, while still advertising a large headline sum insured.
Example
Your Rs 15 lakh policy has a Rs 50,000 sub-limit on cataract surgery. The surgery costs Rs 85,000. The policy pays Rs 50,000 and you pay Rs 35,000, even though most of your cover is untouched.
Common mistakes
- Judging a policy only by its sum insured and ignoring the sub-limit schedule.
- Not realising room rent and ICU caps are sub-limits too.
Frequently asked questions
Which treatments usually have sub-limits?
Cataract, some joint-replacement and named surgeries, ambulance, and sometimes modern or day-care procedures. The exact list is in your policy schedule.
Are there policies without sub-limits?
Yes. Many comprehensive plans advertise no disease-wise sub-limits and no room-rent cap. Confirm this in the wording, not just the brochure.
