What Are Sub-limits in Health Insurance and How Do They Affect Me?

Ever wondered why your health insurance plan does not cover the full hospital bill? It's because of sub-limits.

It is a cap that your insurance company places on policy claims for certain procedures, room rent, ambulance cost, and certain treatments. Sub-limits can impact your coverage and out-of-pocket expenses. Discover how it hits your wallet and surprises you.

What is the Sub-limit in Health Insurance?

A sub-limit in health insurance is a monetary cap on the maximum amount payable for specific medical expenses. This means the insurer will not pay beyond the defined limit, even if your total sum insured is higher.

Suppose your health insurance plan offers a sub-limit of ₹45,000 for the treatment of kidney stones. But due to severe medical complications, your hospital bill for the kidney stone treatment procedures costs around ₹1 lakh. Hence, you have to pay ₹55,000 from your own pocket.

What are the Sub-limits Available in Health Insurance?

1. Disease-Specific Sub-Limits

Disease-specific Sub-limits refer to specific medical conditions or diseases, such as cardiac conditions, chemotherapy, radiotherapy, or orthopaedic procedures. For example, a family health insurance policy may have a ₹2 lakh sub-limit for heart surgery, even if the policy sum insured is ₹8 lakhs.

2. Room Rent Sub-Limits

You can claim room rent, for example, if your health insurance policy offers ₹3,000 per day. Choosing an expensive room means you will have to pay the difference out of pocket. Room rent Sub-limits also reduce the actual hospital bill.

3. Procedure-Specific Sub-Limits

Some health insurance policies provide independent Sub-limits for certain procedures. For example, if your policy provides a ₹40,000 sub-limit for cataract surgery, you will need to cover any additional expenses if the amount exceeds that limit.

4. Ambulance Sub-Limits

Some insurers offer Sub-limits on ambulance expenses for hospitalisation. For example, if your actual ambulance cost is ₹3,000 and the sub-limit is ₹2,000, you'll need to pay the extra ₹1,000.

5. Sub-Limits Related to the Insured's Age

Insurance companies also offer Sub-limits based on the insured person's age. Treatment for an older person may be capped at lower limits because older age groups have higher health risks.

Knowing sub-limits can ensure a smooth claim settlement without any unexpected deductions.
