Co-payment vs Deductible

Key takeaway

A deductible bites hardest on small claims; a co-payment bites hardest on large ones. On a ₹2,00,000 approved claim a ₹25,000 deductible costs the employee less than a 20% co-pay (₹40,000) — but on a ₹40,000 claim the same co-pay is only ₹8,000. The cheaper lever depends entirely on how large the claim turns out.

How each one works in a group/employer plan

Both a co-payment and a deductible shift part of a claim onto the insured employee — but they behave very differently. A deductible is the first slice the employee clears themselves: until the bill crosses that fixed rupee threshold, the insurer pays nothing. A co-payment is a percentage the employee pays on the approved amount, on every eligible claim, with the insurer settling the rest.

The practical difference is how they scale. A deductible bites hardest on small claims — a ₹8,000 bill under a ₹10,000 deductible is paid entirely by the employee. A co-payment bites hardest on large claims — a 20% share of a ₹5,00,000 bill is ₹1,00,000. Some group plans use both: the employee clears the deductible first, then a co-pay percentage applies to the approved amount above it.

Both apply only to the approved claim, after the insurer has removed non-admissible items and any sub-limit excess. The exact wording — the co-pay rate, the deductible amount, and whether the deductible is per-claim or per-year — always lives in the policy document, so confirm it before you communicate the benefit to your team.

Why the difference matters for employers

Co-pay and deductible are both budgeting levers, but they land on different employees. A deductible penalises frequent small claims — routine hospitalisations, day-care procedures — which are exactly the claims most employees actually file. A co-payment penalises the rare, catastrophic claim, the moment an employee is least able to absorb a five-figure bill.

Two plans with the same sum insured and the same premium can therefore feel completely different to your team, depending on which lever you chose. Adding either one — or both — is a clean way to bring a premium inside budget without cutting the sum insured, but it moves cost from a predictable annual premium to an unpredictable day in hospital.

The real risk is a communication gap: if employees meet the deductible or co-pay only at the billing desk, a benefit meant to build goodwill instead breeds resentment. Whatever structure you choose, state both numbers plainly in onboarding so the cover is understood before it is needed.

How Onsurity handles co-pay and deductibles

Onsurity structures group plans around clarity. Where a co-payment or deductible applies, the rate and the amount are stated up front in the member’s policy details inside the Onsurity Super App — not buried in fine print. Many plans can also be built with no voluntary co-payment and no deductible, so an approved cashless claim leaves employees paying nothing beyond genuinely non-admissible items.

Because settlement runs cashless at 10,000+ network hospitals, the insurer’s share is paid straight to the hospital and the employee only settles their deductible or co-pay portion at discharge — no large upfront outlay, no waiting on reimbursement. Day-1 cover options mean the benefit is live from the joining date, with no waiting period on eligible claims.

HR sees every plan’s co-pay, deductible, sum insured and claims status in one place on the TeamSure dashboard, while the Good Doctors claims concierge — real doctors — guides employees through pre-authorisation and discharge, so nobody is surprised by their share of the bill.
