Why your employer's group health insurance is not enough: what it doesn't cover and what to buy instead
Your employer's group health cover has five critical gaps — no portability when you leave, room rent sub-limits that cut all your claims, and sum insured too low for a major illness. Here's what they are and what to buy alongside it.

# Why your employer's group health insurance is not enough: what it doesn't cover and what to buy instead
Your company gives you health insurance. You see it listed in your CTC breakdown, feel reassured, and move on. That reassurance is misplaced.
Employer group health insurance has real value — it covers pre-existing diseases from day one, has no waiting periods, and costs you nothing. But it has five structural gaps that can leave you with a massive bill at the worst possible time. Understanding those gaps is the first step to fixing them.
What does a typical employer group health insurance policy actually cover?
Most employers in India provide a group mediclaim policy with a sum insured of ₹3 lakh to ₹5 lakh. Larger companies may offer ₹5 lakh to ₹10 lakh, but ₹3–5 lakh is the norm for mid-size and small employers.
The policy typically covers:
- The employee
- Spouse
- Dependent children (up to age 25 or 26 in most policies)
- Dependent parents (in some policies, not all)
Pre-existing diseases are usually covered from day one — this is the single biggest advantage over individual policies, which impose waiting periods of 2–4 years.
But the sum insured, the sub-limits, the co-pay clauses, and the portability rules are where things fall apart.
What happens to your health cover when you quit or lose your job?
Your cover ends the day your employment ends. Not after 30 days. Not at the end of the month. On the day you leave.
This is the most underappreciated risk in the entire employer group insurance framework. If you are hospitalised on day 15 after leaving your job, you have no cover.
Now here is the part most people get wrong: you cannot port a group health insurance policy to an individual policy. IRDAI's portability rules allow you to transfer an individual or family floater policy from one insurer to another — and your waiting period credit transfers with you. But that portability right applies only to individual policies, not group policies.
If you try to buy an individual health policy after leaving a job where you only had group cover, the insurer treats it as a brand-new policy. A fresh 2–4 year waiting period for pre-existing diseases starts from scratch. If you have diabetes, hypertension, or any other pre-existing condition, it will not be covered for those initial years.
The practical solution: buy an individual or family floater policy while you are still employed and healthy. The group policy runs alongside it, and your individual policy builds continuity credit over time.
How do room rent sub-limits reduce your entire claim — not just the room cost?
This is the gap that surprises people the most, and it works in a non-obvious way.
Many group policies cap room rent at 1% of sum insured per day. On a ₹5 lakh policy, that is ₹5,000 per day. On a ₹4 lakh policy, that is ₹4,000 per day.
Here is what most people do not realise: if your actual room rent exceeds the sub-limit, the insurer does not just deduct the excess room cost. It applies a proportionate reduction to every other expense in your claim — doctor fees, nursing charges, surgical fees, ICU charges, everything.
The formula: if you took a room that costs twice the allowed limit, the insurer pays roughly 50% of all related expenses.
Worked example: Vikram's appendix surgery in Mumbai
Vikram is 30 years old. His employer provides a ₹4 lakh group health policy. He is admitted for an appendicectomy at a mid-range private hospital in Mumbai.
Hospital bill breakdown:
- Room rent: ₹8,000/day for 3 days = ₹24,000
- Surgeon and anaesthetist fees: ₹80,000
- OT charges and consumables: ₹60,000
- Medicines, nursing, diagnostics: ₹1,56,000
- Total bill: ₹3,20,000
Policy room rent sub-limit: 1% of ₹4 lakh = ₹4,000/day
Room rent ratio: Allowed ₹4,000 / Actual ₹8,000 = 50%
Because Vikram's room exceeded the sub-limit, the insurer applies a 50% proportionate reduction to all expenses.
Insurer pays: 50% of ₹3,20,000 = ₹1,60,000
Vikram pays out of pocket: ₹1,60,000
Vikram had health insurance. He still paid ₹1.6 lakh for a ₹3.2 lakh surgery. The room rent sub-limit cut his effective coverage in half.
Had his policy had no room rent sub-limit, the insurer would have paid the full ₹3.2 lakh (within the ₹4 lakh sum insured limit).
Is ₹5 lakh sum insured enough for a serious illness in 2026?
No. Not in a tier-1 city, and increasingly not in tier-2 cities either.
Here is what major treatments cost in private hospitals in metro cities:
- Cardiac bypass surgery: ₹3–6 lakh
- Knee replacement (single): ₹2.5–4 lakh
- Cancer treatment (chemotherapy, 6–8 cycles): ₹6–18 lakh depending on drug protocol
- Liver transplant: ₹25–35 lakh
- Stroke treatment with ICU stay of 10+ days: ₹4–8 lakh
A ₹5 lakh sum insured covers a cardiac bypass if you pick the right hospital. It does not cover cancer chemotherapy. It does not cover most organ transplants.
Healthcare cost inflation in India runs at roughly 14% per year, faster than general inflation. A surgery that costs ₹5 lakh today will cost roughly ₹9 lakh in five years at that rate.
If you live in Mumbai, Delhi, Bengaluru, Hyderabad, or Chennai, the recommended minimum individual sum insured is ₹10 lakh. For families with dependents, ₹15–20 lakh family floater is the reasonable baseline.
What is a co-pay clause and how does it affect your claim?
Some group policies — especially those with older employees or certain employer cost-containment structures — include a co-pay clause. Co-pay means you agree to bear a fixed percentage of every claim.
A 10% co-pay on a ₹3 lakh bill means you pay ₹30,000 regardless of your sum insured balance. A 20% co-pay means ₹60,000 out of pocket.
Co-pay clauses are more common in individual policies for people above 60, but they appear in some group policies too. Check your policy document — it will be mentioned in the terms and conditions section.
When buying an individual policy, look for zero co-pay. If co-pay is unavoidable (common for senior citizen plans), cap it at 10% and understand the arithmetic before you need it.
Why does starting an individual health policy at 25 instead of 35 matter?
Two reasons: waiting periods and no-claim bonuses.
Waiting periods: Individual policies have a 2–4 year waiting period for pre-existing diseases and typically a 1–2 year waiting period for specific illnesses like hernias, cataracts, and joint replacements. If you buy at 25, these waiting periods expire by the time you are in your late 20s — the decade when most people start developing lifestyle conditions. If you buy at 35, you are mid-career and mid-health risk before you have full coverage.
No-claim bonus (NCB): Most individual policies give you a 10–50% increase in sum insured for every claim-free year. If you start at 25 with a ₹10 lakh policy and make no claims for 5 years, your effective sum insured may grow to ₹15 lakh with no additional premium. That continuity benefit is lost if you wait until 35 to start.
Premium impact: Health insurance premiums increase sharply with age. Locking in at 25 gives you lower base premiums. Every year you delay costs you both a higher premium and a lost year of continuity benefit.
What should you buy alongside your employer group health cover?
Option 1: Individual or family floater policy
Buy a separate individual or family floater policy while you are employed. This runs parallel to your group cover and builds continuity credit.
Minimum sum insured: ₹5 lakh individual, ₹10 lakh in metros and for families.
Features to look for:
- No room rent sub-limit (or sub-limit of at least 1.5–2% of sum insured)
- No co-pay clause
- Restore or refill benefit (reinstates sum insured if fully exhausted within a policy year)
- No-claim bonus of at least 25% per year
- Network hospitals: check the insurer's cashless hospital list for your city specifically
- Claim settlement ratio: look for insurers with 90%+ claim settlement ratio in the IRDAI annual report
Annual premium benchmark (2026): A ₹10 lakh individual policy for a 30-year-old non-smoker typically costs ₹8,000–14,000 per year depending on insurer and features.
Option 2: Super top-up policy
A super top-up is a cost-effective way to add high coverage without paying full individual policy premiums.
A super top-up with a ₹20 lakh sum insured and ₹5 lakh deductible kicks in after your primary cover (group policy) is exhausted. You pay premiums only on the top-up layer. For a 30-year-old, a ₹20 lakh super top-up with ₹5 lakh deductible may cost ₹3,000–6,000 per year.
Combination that works: ₹5L group policy + ₹5L individual policy + ₹20L super top-up (₹5L deductible) = ₹25L effective cover for roughly ₹15,000–20,000/year in total premiums.
Key Takeaways
- Your employer group health policy ends on your last day of employment — there is no grace period and no portability to individual cover without fresh waiting periods.
- Room rent sub-limits reduce your entire claim proportionately, not just the excess room cost — a ₹8,000/day room on a ₹4,000/day sub-limit policy can cut your total payout by 50%.
- ₹5 lakh sum insured does not cover most serious illnesses in metro cities in 2026; ₹10 lakh is the realistic minimum.
- Co-pay clauses in group policies can cost you ₹30,000–60,000 out of pocket even when your sum insured is not exhausted.
- Buying an individual policy at 25 rather than 35 saves waiting period years, locks in lower premiums, and earns a decade more of no-claim bonus.
- The most cost-effective structure is a base individual policy (₹5–10L) plus a super top-up policy for larger coverage, running alongside your group cover.
FAQ
Can I port my employer group health insurance to an individual policy when I resign?
No. IRDAI's portability rules apply only to individual and family floater policies — you can move between insurers and carry your waiting period credit. A group policy to individual policy switch is treated as a new policy, and fresh waiting periods of 2–4 years apply for pre-existing diseases. The time to buy an individual policy is before you resign, while you are still healthy and have no immediate claims pressure.
What is a room rent sub-limit in health insurance and how does it work?
A room rent sub-limit caps the daily room rent your insurer will pay — typically 1% of sum insured per day. If your actual room rent exceeds this limit, the insurer reduces all related claim expenses (surgeon fees, nursing, medicines) in the same proportion. On a ₹5 lakh policy with a 1% sub-limit (₹5,000/day), choosing a ₹10,000/day room means the insurer pays only 50% of your total hospitalisation bill, not just the excess room cost.
How much health insurance do I need if I live in Mumbai or Delhi?
Financial planners generally recommend a minimum of ₹10 lakh individual sum insured for residents of metro cities, given hospital costs and medical inflation. For a family of four, a ₹15–25 lakh family floater is a reasonable baseline. Adding a super top-up policy on top of a base individual policy is a cost-effective way to reach ₹25–50 lakh in total coverage without paying full premiums for the entire amount.
What is a super top-up health insurance policy and is it better than a regular top-up?
A super top-up pays claims once your total hospitalisation expenses in a policy year cross a deductible threshold — regardless of how many separate claims make up that total. A regular top-up applies the deductible per claim. Super top-ups are almost always the better choice because a single long illness or multiple smaller hospitalisations in the same year both trigger the cover. Premiums are significantly lower than equivalent individual policy cover.
Does employer health insurance cover parents in India?
It depends on the employer's policy. Some companies include dependent parents as part of the standard group cover; others offer parental cover as an optional add-on that may require an extra premium contribution from the employee. Check your policy document or HR policy explicitly. Even where parents are covered under a group policy, the same portability and sum insured limitations apply — so an independent senior citizen health policy for parents is advisable.
