"It's covered by the company" is one of the more expensive assumptions a salaried employee can make. Group health insurance is genuinely useful — but it's built for the company's budget, not your specific situation, and it has real edges you'll only discover when you hit them. This guide covers exactly what those edges are, and what a sensible personal safety net looks like alongside it.
None of this is an argument against accepting or valuing employer-provided health cover — it's a genuinely useful benefit and worth using. The point is narrower: treating it as complete, permanent, and sufficient on its own is where the real risk sits, and that risk is inexpensive to close once you know specifically what to check and what to add.
The gap that catches people off guard
Your employer's policy stops the moment you stop being an employee — the day you resign, are let go, or retire. If a health event happens during a notice period, a job search, or right after a job switch with a coverage gap between employers, you can be left without any cover at exactly the wrong time — often precisely when income is also uncertain, compounding the risk.
This gap is rarely communicated clearly at the time you join a company — the group policy is usually presented as a straightforward employee benefit during onboarding, with the coverage-ends-at-exit detail buried in policy documentation most people never read closely. It's worth pulling up your specific group policy's terms at least once, rather than only discovering the actual scope of coverage during a claim or right as you're leaving a job.
Common limitations in a typical group policy
| Limitation | What it means in practice |
|---|---|
| Room rent sub-limits | A cap on the daily hospital room charge covered — exceeding it can trigger proportionate deductions on the entire bill, not just the room. |
| Disease-specific caps | Certain conditions may have a lower payout ceiling than your overall sum insured. |
| No cover after resignation | Coverage typically ends immediately, sometimes with a short grace window at best. |
| Family members may be limited | Parents or in-laws are often excluded, or covered only as an add-on with extra premium. |
| Pre-existing condition rules reset | Switching jobs can mean a new waiting period on pre-existing conditions with the new employer's insurer. |
| Co-payment clauses | Some group policies require you to pay a percentage of the bill yourself, particularly for specific treatments or age groups. |
Room rent sub-limits, in detail
This is the single most common source of an unpleasant claim-time surprise, worth understanding properly rather than just knowing it exists. Say your policy caps room rent at Rs. 3,000/day, but the hospital room you're actually admitted to costs Rs. 5,000/day. Many policies apply a proportionate deduction across the entire bill, not just the room charge — meaning if your room rate is 40% over the cap, the insurer may reduce reimbursement across other related charges (doctor fees, procedure costs, diagnostics) by a similar proportion, not just refuse the extra room cost. This can turn what looks like a small room-rate overage into a meaningfully larger out-of-pocket cost across the entire hospitalisation.
Metro city hospitals in particular often price standard rooms above common sub-limits found in more basic group policies, making this a genuinely live risk for anyone likely to be hospitalised in a major city — worth checking your specific sub-limit against realistic room rates at hospitals you'd actually use, not just assuming the cap is generous enough.
A growing number of newer policies, both group and personal, have moved away from a fixed rupee room-rent cap toward "no room rent capping" or category-based limits (like "single private room" rather than a specific daily rupee figure) — these structures are generally more favourable to the policyholder and worth specifically looking for when comparing options, since the traditional fixed-rupee cap hasn't kept pace with rising hospital room costs in many cities over recent years.

What to actually check in your policy
- The sum insured — is it a family floater shared across everyone, or an individual amount per person? A shared floater can be exhausted quickly if multiple family members need care in the same year.
- The room rent limit — a low cap in a metro city hospital is easy to exceed, as covered above.
- Whether parents are covered, and at what additional cost if not automatic.
- The waiting period for pre-existing conditions and specific procedures — this resets with each new employer's policy in many cases.
- Whether OPD (outpatient) expenses are covered at all — many group policies only cover hospitalisation, not routine doctor visits or diagnostics.
- Co-payment clauses — some policies require you to bear a percentage of costs yourself, which meaningfully changes your real out-of-pocket exposure even with a large-sounding sum insured.
- The network hospital list — cashless treatment is only available at hospitals within your insurer's network; anywhere else requires paying upfront and claiming reimbursement.
Why a personal policy still makes sense even with employer cover
- Continuity — it doesn't disappear when you change jobs or leave the workforce, including career breaks or a transition to freelance/business work.
- Higher, more flexible sum insured — you choose the cover level, not your employer's HR budget, and can increase it as your life circumstances (marriage, children, ageing parents) change.
- No dependence on employer's insurer choice — network hospitals and claim experience vary meaningfully by insurer, and you have no say in which insurer your employer selects.
- Tax benefit — premiums paid for a personal policy are eligible for deduction under Section 80D, separate from anything your employer provides, which group policies typically don't offer since the employer usually bears that premium directly.
- No-claim bonus accumulation — many personal policies increase your sum insured over successive claim-free years, a benefit that resets or doesn't apply when you're dependent on a rotating employer-provided policy.
The tax angle: Section 80D
Under the old tax regime, premiums paid for a personal health insurance policy are deductible under Section 80D — commonly up to Rs. 25,000 for yourself, your spouse, and dependent children, with a higher limit (commonly up to Rs. 50,000) if you're also paying for senior citizen parents' health insurance. This is a separate deduction limit from Section 80C, meaning it doesn't compete with your PPF, ELSS, or life insurance deductions for the same room — it's genuinely additional deduction capacity, on top of protection your employer's group policy typically doesn't provide any tax benefit for at all, since the premium there is usually paid or subsidised by the company rather than by you directly.
A reasonable starting point for cover
A personal policy with at least Rs. 5–10 lakh of cover, taken independently of your employer, is a common baseline for a single young professional in a metro city — higher if you're the primary earner for a family, given rising hospitalisation costs, particularly for serious illnesses or extended treatment. Many people supplement a base policy with a super top-up plan — a lower-cost policy that activates only after a specified threshold is crossed, providing much higher total cover for a relatively modest additional premium, without needing to buy an equivalently large base policy outright.
As a rough illustration of how this stacks: a Rs. 5 lakh base policy paired with a Rs. 20 lakh super top-up activating above that threshold gives effective protection up to Rs. 25 lakh, at a combined premium typically well below what a single Rs. 25 lakh base policy would cost outright. This layered structure is a genuinely efficient way to reach meaningful total cover without the premium scaling linearly with the sum insured, which is how base policies tend to price as they get larger.
Porting between insurers
If you're unhappy with your current insurer's claim experience, network, or pricing, porting — switching to a new insurer while preserving your accumulated waiting-period credit and no-claim benefits — is a legal right in India, not something insurers can simply refuse without valid reason. This is a meaningful option worth knowing about specifically because it removes the biggest reason people stay with an underperforming policy: the fear of restarting waiting periods from zero. Porting has its own timeline requirements (typically initiated a specific number of days before your renewal date), so it needs planning ahead rather than a same-day decision.
Cashless vs reimbursement claims
A cashless claim lets the hospital bill the insurer directly for treatment at a network hospital, meaning you don't pay upfront out of pocket (beyond any non-covered items or co-payment). A reimbursement claim applies when you're treated outside the network, or occasionally when cashless approval is delayed or partially denied — you pay the full bill yourself, then submit documentation to claim it back. Cashless is meaningfully more convenient during an already stressful situation, which is one more reason checking your specific insurer's network hospital list in advance — ideally including a hospital near your home, not just a well-known one across town — is worth doing before you need it, not during an emergency.
What health insurance doesn't cover: lost income
A detail worth being aware of regardless of how good your health cover is: standard health insurance reimburses medical costs, not lost income during a recovery period. A serious hospitalisation or extended illness can mean weeks or months away from work, and unless your employer's sick leave policy fully covers that period, the income gap itself isn't something a standard health policy addresses at all. This is where a separate critical illness rider or policy (mentioned in our term insurance guide) fills a genuinely different gap — it pays a lump sum on diagnosis of a covered condition, usable for whatever the situation actually requires, including lost income, rather than being restricted to hospital bills.
Pre-existing conditions and waiting periods, in practice
Most health policies, group and personal alike, impose a waiting period before covering pre-existing conditions, commonly ranging from 1 to 4 years depending on the insurer and specific condition. What's less well understood: switching employers, and therefore switching group insurers, can effectively restart this waiting period under the new company's policy, even if you'd already served most or all of it under your previous employer's plan. A personal policy, held continuously regardless of job changes, avoids this repeated resetting — one more concrete way job-switching and health insurance interact in a way that's easy to overlook until it directly affects a claim.
Mistakes people make
- Assuming employer cover is sufficient without ever checking the actual sum insured, room rent limit, or exclusions specific to that policy.
- Not buying a personal policy "because I'm covered at work," then facing a genuine coverage gap during a job transition, precisely when a personal safety net matters most.
- Ignoring the room rent sub-limit until a hospitalisation reveals it, at which point the proportionate deduction is already applied to the bill.
- Letting a personal policy lapse during a period of employer coverage, then discovering a new waiting period applies when re-purchasing later, right when it's needed again.
- Not checking if parents are covered before assuming they are, particularly relevant as parents age and healthcare needs increase.
- Staying with an underperforming insurer purely to avoid restarting a waiting period, without realising porting preserves that continuity.
The bottom line
Employer health insurance is a genuine benefit, not something to dismiss — but treating it as your entire health safety net is a common, understandable, and avoidable mistake. The specific gaps covered here — no coverage after resignation, room rent sub-limits, waiting periods that can reset with each job change, parents often excluded by default — are exactly the details that don't matter until the moment they suddenly do. A modest personal policy running quietly alongside your employer's cover, plus a genuine understanding of your group policy's actual terms rather than an assumption of adequacy, closes nearly all of these gaps for a comparatively small ongoing cost.
Frequently asked questions
Does my company health insurance cover me the day I resign?
Usually not. Group health insurance typically ends on your last working day, sometimes with a short grace window at best. A personal policy running in parallel avoids this gap entirely, regardless of when or why you leave a job.
Is it worth buying personal health insurance if my company already covers me?
Yes, for most people. A personal policy provides continuity across job changes, a sum insured you control rather than one set by your employer's budget, and eligibility for a Section 80D tax deduction that group cover typically doesn't offer.
What is a room rent sub-limit and why does it matter?
It's a cap on the daily hospital room charge your policy will cover. Exceeding it can trigger a proportionate deduction across your entire hospital bill, not just the room charge — a mechanism that surprises many people at claim time, especially in metro city hospitals where room rates are higher.
Are my parents covered under my company health insurance?
Often not automatically, many group policies cover only the employee and immediate family, with parents available only as a paid add-on if offered at all.
What is a super top-up health policy?
A lower-cost policy that activates only after your base cover is exhausted past a specified threshold, providing much higher total protection for a relatively modest additional premium.
Can I port my personal health policy to a different insurer without losing benefits?
Yes, porting is a legal right in India that preserves your accumulated waiting-period credit and no-claim benefits when switching insurers.
