Health insurance claim rejection is not rare — it is a systemic problem rooted in policy jargon most people never read. This guide breaks down exactly why claims get rejected and what you must do to protect yourself.

7 Reasons Your Health Insurance Claim Gets Rejected
Reason 01
Pre-Existing Disease (PED) Not Disclosed
This is the #1 reason for claim rejection in India. If you had diabetes, hypertension, thyroid, or any other condition before buying the policy and did not disclose it — the insurer can legally reject any related claim, even years later.
✅ Fix: Always disclose every medical condition honestly at the time of policy purchase. Hiding information gives insurers a permanent reason to deny claims.
Reason 02
Waiting Period Not Completed
Most health policies have waiting periods — an initial period during which specific claims are not covered. Common waiting periods: 30 days for general illness, 2–4 years for pre-existing diseases, 1–2 years for specific conditions like hernia, cataract, joint replacement.
✅ Fix: Buy health insurance when you are young and healthy so waiting periods are served before you actually need the coverage.
Reason 03
Treatment Not Covered Under Policy
Every health policy has an exclusion list — procedures and treatments that are simply not covered. Common exclusions include cosmetic surgery, dental treatment, vision correction, experimental treatments, and self-inflicted injuries.
✅ Fix: Read the exclusion list on Page 1 of your policy document before buying. This section is usually in fine print — read it anyway.
Reason 04
Non-Network Hospital Used for Cashless Claim
Cashless treatment is only available at hospitals in your insurer's network. If you go to a non-network hospital for cashless treatment, the claim will be rejected. For reimbursement claims, you can use any hospital — but the process is longer.
✅ Fix: Save your insurer's network hospital list on your phone right now. Check it before any planned procedure. In an emergency, call the insurer helpline immediately.
Reason 05
Wrong or Incomplete Documentation
Insurers require specific documents for claim processing — discharge summary, original bills, doctor's prescription, investigation reports, pharmacy receipts. Missing even one document can lead to claim rejection or delay.
✅ Fix: Always collect and keep all original documents during hospitalization. Ask the hospital's billing department for the complete document checklist your insurer requires.
Reason 06
Claim Filed After the Deadline
Every insurer has a claim intimation deadline — usually 24–48 hours for planned hospitalization and within 7 days for emergencies. Missing this window gives insurers grounds to reject the claim.
✅ Fix: Inform your insurer the moment you know hospitalization is needed. A single phone call or app notification is enough to start the process.
Reason 07
Policy Lapsed Due to Non-Payment of Premium
If you missed your premium renewal date and the policy lapsed, you have no coverage — even if the treatment started just one day after the lapse. Many people forget renewal dates and discover this during a medical emergency.
✅ Fix: Set auto-renewal or a calendar reminder 30 days before your policy renewal date. Most insurers offer a grace period of 15–30 days — use it if needed.
How to Appeal a Rejected Claim
1
Get the Rejection Letter in Writing
Ask your insurer for a formal rejection letter stating the exact reason. This is your right under IRDAI regulations.
2
File a Grievance with the Insurer
Submit a written grievance to the insurer's Grievance Redressal Officer (GRO). They must respond within 15 days as per IRDAI mandate.
3
Escalate to IRDAI Bima Bharosa Portal
If unsatisfied with insurer response, file a complaint at bimabharosa.irdai.gov.in — IRDAI's official grievance portal.
4
Approach the Insurance Ombudsman
For claims up to ₹50 lakh, the Insurance Ombudsman provides free dispute resolution. Find your regional ombudsman at cioins.co.in.
What the New Bima Sugam Marketplace Changes
IRDAI's Bima Sugam digital marketplace, rolling out in 2026, aims to make the claims process more transparent. Key changes: standardised claim forms, real-time claim tracking, and mandatory disclosure of rejection rates by insurers. This gives buyers the power to compare insurers not just on price but on claims experience.
