Insurance Claim Rejected? Top Reasons and How to Appeal

Insurance claims in India are most often rejected because of non-disclosure of a health condition at purchase, a claim during a waiting period, an excluded treatment, missing documents or late intimation. If your claim is rejected, ask for the reason in writing, check it against your policy wording, and appeal in this order: the insurer's Grievance Redressal Officer, then IRDAI's Bima Bharosa portal, then the Insurance Ombudsman. Many rejections are overturned when the policyholder pushes back with the right documents.

First, understand your rights (as of October 2026)

IRDAI's 2024 regulations and master circulars on policyholder protection and health insurance give you several protections:

• No rejection without committee approval. Health insurers cannot repudiate a claim without the approval of a claims review committee, and must state the specific policy clause behind the decision.
• Moratorium: After 5 years (60 months) of continuous health cover, a claim cannot be contested for non-disclosure or misrepresentation, except in proven fraud. Continuous cover under portability or migration counts.
• Pre-existing disease waiting period is capped at 3 years.
• Cashless timelines: Authorisation decision within 1 hour; final discharge authorisation within 3 hours of the hospital's request.
• Life insurance death claims not requiring investigation must be settled within 15 days of receiving all documents.
• Interest on delays: Insurers must pay interest at bank rate plus 2% on claims paid late beyond the prescribed timelines.

The most common reasons claims are rejected

1. Non-disclosure or misrepresentation

Not mentioning diabetes, hypertension, thyroid disorders, past surgeries, smoking or alcohol use in the proposal form is the single biggest cause of rejection, for both health and life policies. If the insurer finds the condition in hospital records, it may deny the claim. After 5 years of continuous health cover, the moratorium protects you except in fraud.

2. Claim during a waiting period

• 30-day initial waiting period for illnesses
• Specific diseases (such as hernia, cataract, joint replacement) with 1-3 year waits
• Pre-existing diseases, up to 3 years

A hospitalisation in these windows for the related condition is typically not payable.

3. Excluded treatment

Cosmetic procedures, certain experimental treatments and other listed exclusions are not covered. Check the exclusions section of the wording.

4. Hospitalisation not medically necessary

If the insurer believes the treatment could have been done on an outpatient basis (for example admission only for tests), it may reject. Day-care procedures listed in the policy are an exception, as they need less than 24 hours.

5. Late intimation or missing documents

Most policies ask you to inform the insurer within a set time (often 24-48 hours of an emergency admission, or before a planned one) and submit documents within a deadline. Delay is often condoned with a genuine reason, but missing discharge summaries, bills or investigation reports can stall the claim.

6. Policy lapsed or grace period issues

If the premium was not paid by the due date and the grace period, a claim in that gap may be denied, and waiting periods may restart for health policies.

7. Suspected fraud or inflated bills

Mismatched dates, duplicate bills or treatment that does not match the diagnosis can trigger rejection or investigation.

8. For life insurance: suicide clause, early-death investigation

Life claims within the first few policy years can be investigated for non-disclosure. A suicide clause typically applies in the first 12 months for many policies. Our guide on how much term insurance cover you need explains why full disclosure at purchase matters.

Rejected vs partly paid: worked example

Many "rejections" are actually deductions. Illustrative senior-citizen health claim:

• Hospital bill: ₹2,40,000
• Non-payable consumables (gloves, PPE, etc.): ₹12,000
• Admissible amount: ₹2,40,000 − ₹12,000 = ₹2,28,000
• Co-payment in policy: 20% → ₹2,28,000 × 20% = ₹45,600
• Insurer pays: ₹1,82,400
• Policyholder pays: ₹57,600 (₹12,000 + ₹45,600)

Here, the deductions follow the contract and an appeal is unlikely to change them. But if the insurer had also applied a room rent proportionate deduction when the policy had no room rent cap, or deducted items that IRDAI standardisation makes payable, you would have a strong case. Always ask for the itemised settlement letter.

Reasons and what you can do

Step-by-step: how to appeal a rejected claim

1. Get the rejection letter. It must cite the specific policy clause. If it does not, ask for it in writing.
2. Read your policy wording, not the brochure, for that clause.
3. Collect evidence: discharge summary, doctor's notes, investigation reports, bills, proof of continuous cover, and a treating doctor's letter addressing the reason for rejection.
4. Write to the insurer's Grievance Redressal Officer (GRO). Details are on the insurer's website and policy document. Insurers are expected to acknowledge immediately and resolve within 14 days.
5. Escalate on Bima Bharosa. If unresolved or unsatisfactory, register on IRDAI's Bima Bharosa portal (bimabharosa.irdai.gov.in), call toll-free 155255 or 1800-4254-732, or email complaints@irdai.gov.in. Bima Bharosa tracks your complaint with the insurer.
6. File with the Insurance Ombudsman. You can approach the Ombudsman if the insurer rejected your complaint, did not reply within one month, or you are not satisfied. File within one year of the insurer's final reply, online at cioins.co.in or at the Ombudsman office for your area. The service is free, no lawyer is needed, and it covers disputes up to ₹50 lakh. Bima Bharosa does not automatically forward complaints to the Ombudsman, so file there yourself.
7. Consumer commission or court, as a last resort, especially for larger claims. You cannot pursue the same dispute before the Ombudsman and a court at the same time.

Insurers must comply with an Ombudsman award within 30 days of acceptance by the complainant.

How to avoid rejection in the first place

• Disclose everything at purchase, including minor conditions and lifestyle habits. See our health insurance checklist.
• Keep cover continuous. Use portability or migration when switching insurers or leaving a job; read is employer health insurance enough.
• Inform the insurer or TPA promptly for every hospitalisation.
• Keep copies of all bills, reports and prescriptions.
• Keep a medical buffer for co-pays and non-payable items, for example in a sweep-in or short FD; an FD calculator shows what such a buffer earns.
• Update nominee details in life policies.
• Pay premiums on time, preferably through auto-debit, and track renewal dates in your budget.

What not to do

• Do not accept a verbal rejection; insist on a written reason.
• Do not sign a "full and final" settlement you disagree with before raising a grievance.
• Do not pay "agents" who promise to get claims passed for a fee.
• Do not miss the one-year deadline for the Ombudsman.

Key takeaways

• Non-disclosure, waiting periods, exclusions, late intimation and missing documents cause most claim rejections.
• IRDAI rules (as of October 2026): 3-year cap on pre-existing disease waiting, 5-year moratorium, cashless decision in 1 hour, discharge approval in 3 hours, and interest at bank rate plus 2% on delays.
• Many "rejections" are partial deductions; ask for an itemised settlement letter.
• Appeal route: insurer GRO (14 days) → Bima Bharosa → Insurance Ombudsman (free, up to ₹50 lakh, within one year).
• Honest disclosure and continuous cover are the best protection.
