Understand sub-limits before they shock your employees.
When HRs evaluate Group Health Insurance for their teams, one of the first things they often check is Sum Insured. A ₹3 lakh or ₹5 lakh policy usually sounds reassuring—more than enough to handle hospitalisation, right?
Unfortunately, that's far from the full picture.
Buried in the fine print of many GMC policies are disease-specific sub-limits—caps on how much the policy will cover for certain medical conditions, regardless of the overall Sum Insured. That’s where the trouble begins.
What Are Sub-Limits in Group Health Insurance?
Sub-limits in group health insurance are predefined caps placed on specific medical expenses—such as particular treatments, procedures, or room rent—within the total sum insured. While the overall sum insured may appear sufficient (e.g., ₹3 lakh or ₹5 lakh), sub-limits restrict how much can be claimed for certain conditions, regardless of the total cover.
These internal caps are usually outlined in policy annexures and can apply to common surgeries, diseases, or services. Sub-limits are typically introduced by insurers to control claim costs and ensure uniformity across insured members.
For HR teams, it’s crucial to recognize that sub-limits directly impact how much the insurer will reimburse, potentially leaving employees to cover the rest out of pocket.
What Are Disease-Specific Sub-Limits in Group Health Insurance?
Think of your company’s group health insurance like a buffet.
You told your employees there’s “unlimited pizza” (₹5 lakh sum insured)...
…but you forgot to mention: “Only two slices per person if it’s pepperoni.”
That’s what a disease-specific sub-limit is.
Disease-specific sub-limits are predefined ceilings set for particular treatments or conditions under a health insurance plan. These act as internal caps within the overall sum insured. In practice, it means that no matter how large your total coverage is, the insurer will only reimburse up to a specified amount for certain procedures.
For example, if your GMC policy includes a sub-limit of ₹40,000 per eye for cataract surgery, and the surgery costs ₹65,000, the remaining ₹25,000 must be borne by the employee—even if their total cover is ₹5 lakh and untouched.
And this doesn’t just apply to cataracts. These sub-limits are often applied to a wide range of common procedures, particularly those seen as “non-critical” or “elective” by insurers.
Common Conditions Affected by Sub-Limits
Here are some of the most frequently capped procedures and how the sub-limit can lead to under-coverage:
What does this mean for HR? It means employees walk into the hospital expecting coverage—and walk out with a hefty bill. And when that happens, the first person they blame is usually not the insurer. It’s you, the HR.
Why These Sub-Limits Are So Often Missed
The issue often lies from how group health insurance decisions are made. HR teams tend to focus on the bigger, more visible aspects—like the total sum insured, premium, hospital network, and whether a top insurer is involved —during policy discussions. Sub-limits on specific diseases are typically hidden deep within annexures or policy footnotes, making them easy to miss. Since they aren’t always discussed openly during renewal or onboarding, both HRs and employees assume full coverage until a claim proves otherwise. Unfortunately, it’s only when a hospitalization occurs that the limitations come to light—leading to surprise deductions, employee dissatisfaction, and reactive troubleshooting.
How to Audit Your Group Health Insurance Policy for Sub-Limits
If you're renewing your company’s GMC plan or switching to a new one, now is the time to audit for sub-limits. Here’s how:
- Request a Sub-Limit Sheet: Ask your broker or insurer for a complete list of all disease-specific caps.
- Benchmark Against Peers: Compare your sub-limits with what similar-sized or industry-aligned companies are offering.
- Check Historical Claims: Look at your past two years of claims data. Look for claims that were only partially paid, or rejected, due to sub-limits.
- Negotiate Key Conditions: Cataracts, hernia, and orthopaedic procedures are some of the most frequently used. Try to raise or remove sub-limits for these. Some modern insurers and brokers now offer plans with no disease-specific sub-limits, or allow HRs to customize them at slightly higher premiums.
What Progressive HR Teams Are Doing
More HR teams today are taking a proactive approach to insurance planning—ensuring policies are reviewed not just for cost, but also for actual usability during claims. Here’s what they’re doing:
- Running onboarding sessions to explain key limitations like sub-limits in simple terms: During onboarding or at the time of renewals, many HR teams take time to explain how the policy works. They help employees understand key aspects like sub-limits, room rent limits, co-pays, and the hospital network—using simple terms and real-life examples.
- Schedule onboarding sessions regularly—not just at renewal time: They don’t limit awareness efforts to annual renewals. HRs collaborate with partners who support monthly or quarterly onboarding sessions for all new joiners.
- Working with brokers who provide monthly dashboards on claim trends: Instead of waiting until year-end, these teams review monthly claim analytics—including how many claims were impacted by sub-limits.
- Creating FAQ guides or videos to address common misconceptions and claim expectations: Instead of expecting employees to read long documents, they create bite-sized formats like FAQs addressing top 10 claim questions, Short videos explaining room rent or sub-limits.
- Auditing and Iterating Every Renewal: They take time to review what worked and what didn’t. They check past claims, see if there were complaints or low payouts, and compare their plan with what other similar companies are offering.
