No-Claim Bonus (NCB) in Health Insurance

How No-Claim Bonus works in a group/employer plan

NCB comes in two shapes. A cumulative bonus adds a percentage of the base sum insured at each claim-free renewal — commonly 5% to 50% a year, up to a stated cap — so the cover grows without the premium rising. A premium-discount NCB instead trims the renewal price while the sum insured stays flat. Group mediclaim policies most often use the cumulative-bonus form.

The bonus builds year on year until it hits the cap, then holds. If a claim is made, a standard clause reduces the accumulated bonus — either fully back to zero or in steps — at the following renewal. An NCB Protect add-on can shield the accumulated bonus against a defined number of claims, so one hospitalisation does not erase years of build-up.

On a group policy the bonus attaches to the policy, not to a single employee, so the uplift applies at the group level and is not portable when an individual changes jobs. Whether NCB is included at all varies by policy: some group plans price renewal on the group’s overall claims ratio instead, so the exact clause always lives in the policy wording.

Why No-Claim Bonus matters for employers

NCB quietly compounds the value of a benefit you are already paying for. A claim-free year does not just keep the premium steady — on a cumulative-bonus plan it hands your team a bigger cover for next year at no extra cost, which is a tangible improvement to communicate at renewal.

It also shapes budgeting decisions. When renewal quotes arrive, understanding whether the uplift comes as extra sum insured or as a premium discount tells you where the value is landing — with employees, or with the finance line. On a group where utilisation is naturally lumpy, an NCB Protect add-on can be worth its cost to stop a single large claim from wiping out an accumulated bonus.

The risk is treating NCB as automatic. Not every group policy carries it, the reset rules differ, and the bonus is tied to the policy rather than to any one employee. Read the clause before you present a growing cover as a promise, so the benefit you describe matches the one in the wording.

How Onsurity handles No-Claim Bonus

Onsurity structures group plans around clarity. Where a plan carries a No-Claim Bonus, the rate, the cap and the reset rules are stated up front and visible in the member’s policy details inside the Onsurity Super App — not buried in fine print you discover only at renewal. HR sees the current sum insured, any accumulated bonus and renewal terms in one place on the TeamSure dashboard.

Because claims settle cashless at 10,000+ network hospitals, employees rarely need to fund treatment upfront and wait on reimbursement — and the Good Doctors claims concierge, staffed by real doctors, guides them through pre-authorisation and discharge so only genuinely necessary claims are raised. That keeps small, avoidable claims down and helps a group hold on to its accumulated bonus.

Day-1 cover options mean the benefit is live from the joining date with no waiting period on eligible claims, and daily primary-care tools like teleconsults help employees resolve minor issues before they ever become a hospitalisation — protecting both their health and the plan’s claim-free record.
