Insurance claim rejection at the moment you need it most is one of the most devastating financial events. Yet many rejections are avoidable — either through proper disclosure at the time of buying, or by knowing how to effectively appeal. This guide covers why claims get rejected, what's genuinely valid, and exactly how to fight a wrongful rejection.
This is the most common reason — and it cuts both ways. If you failed to disclose a pre-existing medical condition, smoking habit, family history of genetic disease, or hazardous occupation when buying the policy, the insurer can reject claims arising from those conditions.
Health insurance policies have waiting periods (typically 2–4 years) for pre-existing diseases. If you're hospitalised for a condition that existed before you bought the policy, during the waiting period, the claim will be rejected. This is contractually valid — understand waiting periods thoroughly before expecting coverage.
Every policy has a list of exclusions — treatments or events not covered. Common health insurance exclusions:
If your policy has lapsed due to missed premium and you didn't reinstate it, claims during the lapse period are rejected. Most insurers give a 30-day grace period after due date — during the grace period, claims are typically paid. After the grace period, the policy is lapsed.
Most policies require claims to be intimated within a specific period of the event (e.g., within 24–48 hours for hospitalisation, within 30 days for death claims). Filing beyond this window can result in rejection — though IRDAI guidelines allow insurers to condone delays for genuine reasons.
Cashless claims are only available at the insurer's network hospitals. Treatment at a non-network hospital requires a reimbursement claim — and rushing to a non-network hospital in an emergency (while valid) means paperwork later, not automatic rejection.
The insurer must provide a written rejection letter with the specific reason. Read it carefully — is the reason factually accurate? Is it a valid exclusion? Sometimes rejections are based on misclassification of treatment or incorrect reading of the policy terms.
Every insurer must have a Grievance Redressal Officer (GRO). File a formal written grievance to the GRO within 30 days of rejection. The insurer must respond within 15 days (IRDAI mandate). Keep documentary proof of filing (email/acknowledgement).
If unsatisfied with the insurer's response (or no response within 15 days): file a complaint on IRDAI's Bima Bharosa portal (bimabharosa.irdai.gov.in) or call the IRDAI toll-free helpline (155255 / 1800-4254-732). IRDAI will take up the grievance with the insurer.
If the insurer still doesn't resolve or the resolution is unsatisfactory, approach the Insurance Ombudsman in your region. The Ombudsman is a quasi-judicial body that resolves insurance disputes free of charge:
For amounts above the Ombudsman threshold or if you disagree with the Ombudsman's award, approach the Consumer Disputes Redressal Commission (District Consumer Forum for up to ₹1 crore; State Commission for ₹1–10 crore; National Commission above ₹10 crore). Consumer courts are generally sympathetic to insurance claimants in genuine cases.
