No Claim Bonus in Health Insurance: Everything You Need to Know

One of the most valuable — yet least understood — benefits in health insurance is the No Claim Bonus (NCB). When you don't make any claims in a policy year, most insurers reward you by increasing your sum insured at no extra premium cost. Over several claim-free years, this can significantly boost your effective coverage.

How Does NCB Work in Health Insurance?

At each renewal, if you have not made any claim in the preceding year, your insurer adds a percentage of the sum insured as a bonus — typically 10–50% per claim-free year. This accumulates up to a maximum, usually 50–100% of the base sum insured.

For example, with a ₹10 lakh policy offering 10% NCB per year:

  • Year 1 (no claim): Sum insured becomes ₹11 lakh at renewal
  • Year 2 (no claim): ₹12 lakh
  • Year 5 (no claim): Up to ₹15 lakh (50% cap in many plans)

NCB as Sum Insured Increase vs Premium Discount

Unlike motor insurance NCB which reduces your premium, health insurance NCB usually increases your sum insured while keeping the premium the same. Some plans offer both — a choice between reduced premium or increased sum insured. Given medical inflation, choosing sum insured increase is almost always the better option.

What Happens When You Make a Claim?

Most health insurance policies reset the NCB to zero when you make a claim. If you had accumulated ₹5 lakh of NCB on a ₹10 lakh policy, a claim in year 6 resets your sum insured back to ₹10 lakh at the next renewal. This is the primary risk of the NCB structure.

However, premium plans like Niva Bupa ReAssure 2.0 and HDFC Ergo Optima Secure offer NCB protection — where the NCB is only partially or not at all reduced after a claim, as an add-on or built-in feature.

NCB Protection Add-On: Is It Worth Buying?

NCB protection riders prevent your bonus from being reset (or reduce the reset penalty) after a claim. The cost is typically 5–10% extra on your premium. If you have accumulated significant NCB — say ₹4–5 lakh in bonus sum insured — paying a small additional premium to protect it makes excellent financial sense.

  • Care Supreme: 10% NCB per year, up to 50% of SI, with NCB protection option
  • HDFC Ergo Optima Restore: 50% instant bonus on base SI + restore benefit
  • Aditya Birla Activ Health: Earn health returns (up to 30% of premium) for healthy behaviour
  • Niva Bupa ReAssure 2.0: NCB accumulated as booster, rollover benefit

NCB and Policy Portability

When you port your health insurance policy, your accumulated NCB transfers to the new insurer — but only at the amount recognized by the new insurer. If your NCB was ₹5 lakh with insurer A, but insurer B's maximum NCB for that plan is ₹3 lakh, you carry forward only ₹3 lakh. Always confirm NCB portability terms before switching.

Tips to Maximize Your NCB

  1. Avoid small claims: For hospitalizations below ₹20,000–₹30,000, consider paying out of pocket and preserving your NCB (especially if it's accumulated over multiple years)
  2. Use NCB protection wisely: Buy this add-on once your accumulated NCB represents significant coverage
  3. Review annually: Make sure your policy document correctly reflects accumulated NCB at each renewal
  4. Don't let policy lapse: A break in policy resets your NCB and waiting periods simultaneously

Conclusion

No Claim Bonus is a powerful mechanism that rewards healthy policyholders with better coverage over time. Understand how your specific plan handles NCB accrual and reset, and use the protection add-on strategically. Over a decade of claim-free renewals, NCB can effectively double your sum insured — at no additional cost.
