Sub-limits and room rent limits

What are sub-limits and room rent limits?

A sub-limit is a cap on how much a health policy pays for a specific expense, illness or treatment, set below the overall sum insured. A ₹10 lakh policy might pay no more than ₹50,000 for a cataract operation, or no more than 1% of the sum insured per day for the hospital room. Anything above the sub-limit is borne by the policyholder, even if the rest of the sum insured is unused.

IRDAI's Customer Information Sheet format, issued with the 2024 Master Circular on Health Insurance Business, describes a sub-limit as a pre-defined limit above which the insurer will not pay. Every sub-limit must be listed in that sheet.

How sub-limits work in Indian health insurance

Sub-limits come in a few common forms:

Room rent and proportionate deduction. Room rent is the most consequential sub-limit because of how hospitals bill. Many hospitals charge more for doctors' visits, nursing and some procedures when the patient is in a costlier room. Policies with a room rent cap therefore often apply a proportionate deduction: if the patient stays in a room costing more than the eligible rent, the insurer reduces the related charges in the same ratio. Which charges are reduced, and which are left out (such as medicines and implants in many wordings), is set by each policy.

Worked example. A ₹5 lakh policy allows room rent of ₹5,000 a day. The patient chooses a ₹10,000 room for four days. The admissible bill, apart from items outside the proportionate clause, is ₹2,40,000, of which ₹40,000 is room rent.

The patient bears ₹1,20,000, far more than the ₹20,000 room rent difference. The figures are illustrative and the actual clause varies by product.

Modern treatments. The 2024 health master circular asks insurers to try to cover technological advances and names examples, including robotic surgery, oral chemotherapy, immunotherapy with monoclonal antibodies, intra-vitreal injections, deep brain stimulation, stereotactic radio surgery and stem cell therapy for certain blood conditions. Many products cover these, but some still do so with sub-limits.

What sub-limits mean for distribution

Sub-limits explain most of the gap between "the claim was settled" and "the claim was paid in full". They also explain why two policies with the same sum insured and similar premium can pay very different amounts on the same bill.

Points for advisers and sales managers:

• Ask about room rent first. Whether the policy has no room rent cap, a single private room limit, or a percentage cap is the single most useful question in a health comparison. For metro customers, a 1% cap on a small sum insured may not cover a standard private room.
• Explain proportionate deduction with numbers. The worked example above is the conversation that prevents a complaint later. Customers who know the rule can pick an eligible room at admission.
• Watch disease-wise caps for older customers. Cataract, joint replacement and prostate procedures are common in later life, and fixed caps on them can be well below city hospital prices.
• Compare like with like. Comparison tools that rank by premium alone reward products with tight sub-limits. Distribution teams should show sub-limits alongside price.
• Read with co-pay and deductible. A single claim can be cut by a sub-limit, a co-payment and a deductible. Customers should see how they stack.
• Claim communication. IRDAI requires insurers to explain any partial disallowance with reference to the specific policy terms. A distributor who can read that letter and explain it keeps the customer's trust at renewal.
