Sum Insured in Group Health Insurance
In group health insurance, the sum insured is the maximum amount an insurer will pay for covered medical claims for an insured member in a policy year. Once claims exhaust it, further costs fall on the employee until the policy renews. It can be structured per-employee or shared across a family.

Key takeaway
The sum insured is set per member — each employee carries their own annual ceiling, so one colleague’s large claim never eats into another’s. It resets in full at every renewal.
How it works in a group/employer plan
When an employer buys a group policy, they set a sum insured that applies to each covered member — not to the company as a whole. Every employee effectively carries their own annual ceiling, so a large claim by one person never eats into a colleague’s cover. The insurer tracks each member’s remaining balance across the policy year and settles cashless or reimbursement claims up to that figure.
The sum insured can be arranged two ways. In an individual structure, each employee and each dependent has a separate limit. In a floater structure, an employee and their added family members share a single pool. Floater cover is usually cheaper for the same headline number, but a single serious claim can consume the family’s entire limit for the year.
Two things sit alongside the sum insured and decide how far it actually stretches: co-payment (the share of each claim the member pays) and room rent limits and sub-limits (caps on specific charges). A ₹5,00,000 sum insured with a restrictive room-rent cap can still leave a shortfall, so employers should read the full plan design, not just the headline figure.
A worked example
Suppose an employer sets a ₹5,00,000 per-employee sum insured with a 10% co-payment and no room-rent restriction. An employee is hospitalised for surgery and the final bill is ₹3,20,000.
| Hospital bill (covered charges) | ₹3,20,000 |
| Less: 10% co-payment (member pays) | – ₹32,000 |
| Paid by insurer from sum insured | ₹2,88,000 |
| Sum insured remaining this year | ₹2,12,000 |
The insurer pays ₹2,88,000 and the employee pays ₹32,000 as co-payment. Because ₹2,88,000 was drawn down, ₹2,12,000 of the ₹5,00,000 sum insured stays available for any further hospitalisation in the same policy year. At renewal, the full ₹5,00,000 is restored — and on plans with a restoration benefit, an exhausted limit can even be reinstated mid-year for an unrelated illness.
Why it matters for employers
The sum insured is the single biggest lever on both the value your team feels and the premium you pay. Set it too low and a serious hospitalisation leaves employees paying out of pocket — the exact moment a benefit is meant to protect them, and the moment goodwill is lost. Set it far above what your team’s age and city profile need, and you overspend without a matching improvement in cover.
A practical approach is to match the sum insured to hospital costs in the cities where your people live, layer a top-up cover for catastrophic events rather than inflating the base limit, and check the waiting period and sub-limits so the headline number is genuinely usable from day one.
How Onsurity handles it
Onsurity lets employers choose a per-employee sum insured that fits the team, with day-1 cover options so there is no wait before the limit can be used. Claims are cashless at 10,000+ network hospitals across India, so employees rarely pay upfront and then chase reimbursement — the covered amount is settled directly against the sum insured at discharge.
The TeamSure dashboard shows each member’s sum insured, what has been used and what remains, alongside onboarding, renewals and billing — so HR can manage cover without spreadsheets or broker calls. When a claim is in motion, the Good Doctors claims concierge — a team of real doctors — guides employees through hospitalisation, pre-authorisation and paperwork, so the sum insured is actually put to work when it matters.
Because plans are customisable, employers can size the base sum insured, add top-up cover, and shape dependent inclusion to their budget and team profile — all on a flexible monthly subscription.

Frequently asked questions
Is the sum insured per employee or shared by the whole team?
In a group plan the sum insured is defined per member. Every covered employee gets their own annual limit — for example ₹5,00,000 each — so one colleague’s large claim does not reduce anyone else’s cover. Where dependents are added, the structure can be individual (each person has their own limit) or floater (the family shares one pool), depending on how the employer sets up the plan.
Does the sum insured reset every year?
Yes. The sum insured is an annual limit tied to the policy year. It is fully restored at each renewal, regardless of how much was claimed in the previous year. Some plans also add a restoration or refill benefit that reinstates the amount mid-year if it is exhausted by an earlier claim.
What happens if a hospital bill is larger than the sum insured?
The policy pays up to the sum insured and the balance is borne by the employee. This is why employers pair an adequately sized base cover with options like top-up cover or a higher tier, so a single serious hospitalisation does not leave staff out of pocket.
How much sum insured should an employer choose?
For most Indian metros, ₹3,00,000 to ₹5,00,000 per employee is a practical starting point, with ₹7,50,000 or more for senior or older members where treatment costs run higher. The right figure depends on your team’s age mix, city-tier hospital costs and budget — a higher sum insured raises the premium but reduces the chance of an uncovered shortfall.
Do sub-limits reduce the sum insured?
Sub-limits do not reduce the headline sum insured, but they cap what can be claimed for specific items — room rent, ICU, or named procedures like cataract. Even with a large sum insured, a low room-rent sub-limit can leave part of a bill unpaid, so the two should be read together.
