Health Insurance · IntermediateWhy Health Insurance Claims Get Rejected — and How to Avoid It (2026)
Written by Priya Nair · Reviewed by the NewEdgePolicy Editorial Team · Updated July 2026
- #1 cause: non-disclosure of a pre-existing condition.
- Claiming during a waiting period (initial, specific-disease or PED).
- Treatment listed as a permanent or specific exclusion.
- Documentation gaps or missed intimation timelines.
- Lapsed policy — a missed renewal beyond the grace period.
- After the 5-year moratorium, non-disclosure can no longer be used to deny a claim (except fraud).
The claim journey — where rejections happen
A claim can be questioned at intimation, at document assessment, or during investigation of a large bill. Understanding the failure points lets you close them before you ever need to claim.
The main reasons claims get rejected
| Reason | What happens | How to avoid it |
|---|---|---|
| Non-disclosure of PED | Insurer finds an undisclosed condition and rejects for misrepresentation. | Disclose every condition. |
| Waiting-period breach | Claim made before the relevant wait ends. | Know your waiting periods before treatment. |
| Policy exclusion | Treatment is permanently or specifically excluded. | Read the exclusions list at purchase. |
| Documentation gap | Missing bills/reports, or late intimation. | Intimate on time; keep every original document. |
| Policy lapse | Premium missed beyond the grace period. | Renew on time; use the grace-period buffer. |
| Non-payable items | Consumables and excluded charges deducted. | Expect standard deductions; not a full rejection. |
Rejection vs deduction — an important difference
Not every reduced payout is a rejection. Insurers routinely deduct co-payment, amounts above room-rent limits, and non-payable consumables. Those are terms of your policy, not a denial.
What to do if a claim is wrongly rejected
- Read the rejection letter — it must state the specific reason and clause.
- Gather evidence — reports, prescriptions, and your disclosure record.
- Escalate to the insurer's grievance officer, then the IRDAI Bima Bharosa portal.
- Approach the Insurance Ombudsman for eligible disputes — it's free.
- Disclose every pre-existing condition on the proposal form.
- Confirm the treatment is past its waiting period.
- Check the exclusions list for the specific procedure.
- Intimate the insurer/TPA within the required window.
- Keep all original bills, reports and discharge summaries.
- Renew before the due date so cover never lapses.
Who should buy / who should be careful
- Everyone benefits from knowing these causes — prevention is free.
- Buyers who disclose fully and read the exclusions at purchase.
- Policyholders who keep organised medical records.
- Don't assume a deduction (co-pay, room rent) is a “rejection.”
- Don't skip intimation timelines — late notice weakens your claim.
- Don't let a policy lapse and then expect a claim to be paid.
Common mistakes to avoid
- Hiding a pre-existing condition to lower the premium.
- Claiming before the waiting period ends.
- Not reading the exclusions before a planned procedure.
- Missing the intimation window or losing original documents.
- Assuming the policy is active when the premium lapsed.
Expert advice
Frequently asked questions
What is the most common reason health claims are rejected in India?
Non-disclosure of a pre-existing condition. When an insurer finds an undisclosed illness during investigation, the claim can be rejected for misrepresentation.
Is a deduction the same as a rejection?
No. Co-payment, room-rent-linked deductions and non-payable consumables are policy terms, not a denial. A rejection means the claim is declined entirely.
Can a claim be rejected after the waiting period ends?
It can, if there was material non-disclosure — until the 5-year moratorium is complete, after which non-disclosure can no longer be used except in cases of fraud.
What can I do if my claim is wrongly rejected?
Read the rejection reason, escalate to the insurer's grievance officer, use the IRDAI Bima Bharosa portal, and approach the Insurance Ombudsman for eligible disputes.
Does a lapsed policy affect my claim?
Yes. If the premium is missed beyond the grace period, cover ends and claims during the lapse are not payable.
