Health Insurance Claim Denied for Pre-Existing Disease or Non-Disclosure: India Recovery Guide
A rejection letter saying “pre-existing disease” or “non-disclosure” feels final only because it is written in insurer language. It is not always the last word. In many cases the winning move is not anger, but a better file: policy wording, proposal form, discharge summary, doctor clarification, claim rejection letter, and a short chronology that forces the insurer to answer the exact ground of denial.
This guide explains what to do when a cashless or reimbursement health insurance claim is denied in India for pre-existing disease, alleged non-disclosure, waiting period, moratorium, or medical-history mismatch.
Quick Answer
- Ask for the repudiation letter in writing with the exact policy clause.
- Get the proposal form and medical declaration relied on by the insurer.
- Ask the hospital or doctor to clarify any wrong “past history” note.
- File a written grievance with the insurer's grievance officer.
- If unresolved, escalate at Bima Bharosa.
- If still unresolved and eligible, approach the Insurance Ombudsman.
- After 60 continuous months of health cover, contesting a claim for non-disclosure is restricted except for established fraud under the 2024 health insurance framework. Check the exact policy dates and enhanced-sum-insured dates.
Why Insurers Use "PED" and "Non-Disclosure"
Two issues are often mixed up.
Pre-existing disease waiting period
Under the IRDAI health insurance framework, a pre-existing disease is broadly a condition diagnosed, advised, or treated by a physician within the specified period before policy start. The 2024 product regulations reduced the maximum waiting period for disclosed pre-existing diseases to 36 months of continuous coverage, except for specified categories such as overseas travel policies.
If you disclosed the condition and completed the waiting period, the insurer must explain why the exclusion still applies.
Alleged non-disclosure
This means the insurer says you did not tell them a material medical fact while buying, porting, migrating, renewing, or enhancing the policy. The insurer should identify:
- the exact proposal-form question,
- the answer given,
- the medical record relied upon,
- the policy clause invoked,
- how the alleged condition is connected to the claim.
First 48 Hours After Rejection
- Save the rejection email, claim status screenshots, SMS, and TPA notes.
- Ask for a detailed repudiation letter if you only received a portal message.
- Write to the insurer: “Please provide the proposal form, policy clause, medical record and underwriting basis relied upon for rejection.”
- Get a doctor note if the discharge summary incorrectly records old illness, duration, diabetes, hypertension, alcohol history, or symptom onset.
- Do not alter hospital records yourself. Ask for a written correction or addendum.

Complaint Email to Insurer
Subject: Grievance against rejection of health claim - Policy No. [number], Claim No. [number]
Dear Grievance Officer,
My claim for [hospitalisation / procedure] was rejected on [date] citing pre-existing disease / non-disclosure. Please provide the exact proposal-form question, answer, medical record, policy clause, and underwriting basis relied upon.
I dispute the rejection because [brief reason: condition was disclosed / waiting period completed / doctor confirms no prior diagnosis / policy completed 60 months / hospital history note is incorrect]. I am attaching the policy, claim papers, rejection letter, medical records, doctor clarification, and renewal proof.
Please reconsider the claim and issue a reasoned written decision.
Escalate to Bima Bharosa
IRDAI's policyholder guidance expects you to complain to the insurer first. If the insurer does not respond or gives an unsatisfactory response, file at bimabharosa.irdai.gov.in.
Upload a short PDF chronology:
- policy start and renewal dates,
- hospitalisation date,
- claim filing date,
- rejection date,
- insurer grievance date,
- why the rejection is wrong.
Insurance Ombudsman Route
The Insurance Ombudsman can consider partial or total repudiation of claims by life, general, and health insurers. Use it after first approaching the insurer. The Council for Insurance Ombudsmen currently describes a one-year filing window from rejection/unsatisfactory reply/no-reply expiry and a monetary limit of Rs. 50 lakh. Check the current CIO portal before filing because limits and forms can change.
Mistakes That Weaken Health Claim Complaints
- Only calling customer care and never filing a written grievance.
- Not asking for the proposal form.
- Ignoring the exact clause in the rejection letter.
- Accepting a hospital's wrong past-history note without correction.
- Filing a long emotional complaint without medical proof.
- Missing Ombudsman limitation.

FAQ
Can the insurer reject every claim linked to diabetes or hypertension?
No. The insurer must connect the policy terms, disclosure answers, waiting period, and medical facts. Ask for the exact basis in writing.
What if I did not know about the disease?
Say that clearly and support it with medical records. Non-disclosure usually turns on what was known, diagnosed, advised, or treated, not what was discovered for the first time during the claim.
Should I file consumer court directly?
For many individual claims, insurer grievance, Bima Bharosa, and Ombudsman are faster first steps. For high-value or complex disputes, take legal advice on consumer commission limitation and jurisdiction.
