Claim rejected for pre-existing disease: what it means and what to do | CION Cancer Clinics
An insurer can refuse a claim by saying the illness existed before the policy began, or was not disclosed. Families with an inherited gene fault often fear a test result will be treated the same way. A fault is a statement about risk, not a diagnosis, but the wording of your proposal form still matters. This page explains how these refusals work and how to challenge one. At CION Cancer Clinics, our team helps carriers and their families plan checks, next steps and support after a genetic result.

The short answer
What does a pre-existing disease rejection actually mean?
It means the insurer says the illness behind your claim was already there before the policy started. Either it falls inside a waiting period, or it was not disclosed when you applied. It is one of the most common reasons claims are refused in India, and one of the most often challenged. Not every such refusal holds up.
How the regulator defines it
Under the regulator's rules, a pre-existing disease is a condition a doctor diagnosed, or for which medical advice or treatment was recommended or received, in the period before the policy began. That look-back period is now three years. A condition you had no diagnosis for, no advice about and no treatment for does not fit that definition.
Where a gene result fits
A carrier who has never had cancer has not been diagnosed with a disease. The fault raises risk. It does not mean an illness is present. That is the medical position. How an insurer or a court reads it can differ, especially if a form asked directly about genetic tests and the answer left it out.
The most useful document in any dispute is the proposal form you signed. Ask the insurer for a copy if you do not have one.Four common grounds
Why do insurers refuse claims on these grounds?
The refusal letter usually cites one of these. Knowing which one tells you how strong your challenge is.
The illness began before the policy
Records show a diagnosis, a scan or medical advice before the start date. The claim then falls inside the waiting period for pre-existing conditions.
What insurers look for
- A doctor's note mentioning earlier symptoms
- An old scan or biopsy report
- A prescription dated before the policy
A question was not fully answered
The form asked something and the answer given was incomplete. This is called non-disclosure, and it is the ground insurers rely on most often.
A waiting period had not ended
Some policies make you wait before paying for certain illnesses, even brand new ones. This is a different kind of refusal, and your policy schedule lists which illnesses are affected.
Family history is stretched too far
The insurer treats a relative's cancer, or your own carrier result, as if it were your illness. This is the version most worth questioning, because risk is not the same thing as disease.
Family history is not your diagnosis. A carrier result is not a disease.Not sure whether this applies to you?
Ask an oncologistIf a claim is refused
What should you do if your claim is rejected?
Get the reason in writing
Ask for a letter that names the exact clause the insurer is relying on. A phone call or a text message saying the claim is not payable is not enough to challenge.
Gather your papers
Collect the proposal form, the policy schedule, renewal notices and every medical record with its date. Put them in order. The dates usually decide these disputes.
Write to the grievance officer
Every insurer has one. Explain simply why the condition was not pre-existing, attach copies, and keep the acknowledgement they send back.
Use the regulator's portal
If the reply does not satisfy you, register the complaint on IRDAI's Bima Bharosa portal. It tracks the complaint and presses the insurer to respond.
Go to the insurance ombudsman
The ombudsman hears claim disputes free of charge, and you do not need a lawyer. The Hyderabad office covers Telangana and Andhra Pradesh. A consumer commission is another route.
In the refusal letter
The words in a rejection letter, in plain language
- Repudiation
- The formal word for a refused claim. A repudiation letter should say why, and which clause of the policy it relies on.
- Non-disclosure
- Leaving out a fact the proposal form asked about. It is the ground most of these refusals rest on.
- Material fact
- Information that would have changed the insurer's decision to cover you, or the price it charged. A detail that would have changed nothing is not material.
- Waiting period
- Time at the start of a policy when certain claims are not paid. It is listed in your policy schedule.
- Moratorium
- After five years of unbroken health cover, a claim cannot be refused for non-disclosure unless fraud is proven.
- Portability
- Moving a health policy to another insurer while keeping credit for waiting time you have already served.

Being straight with you
What this page cannot tell you
It cannot tell you whether your refusal will be overturned. That turns on your policy wording, the exact questions on your form and the dates in your records. A lawyer, a consumer organisation or the ombudsman can weigh those. This page can only tell you how the process works.
It cannot read your genetic report
Whether a report shows an illness or only a raised risk is sometimes the heart of the dispute. What a specific variant means is a question for the counsellor who ordered the test, who can also put it in writing for you.
Who this does not apply to
If your claim was cut for a reason unrelated to earlier illness, such as a room-rent limit or a missing document, a different route applies. And most people with cancer in the family do not carry an inherited fault at all. Their policies are assessed like anyone else's, and nothing on this page changes that.
Commonly believed
Four things people believe about these refusals
"Once a claim is refused, the decision is final."
Insurers do reverse decisions after a written grievance, and the ombudsman can direct an insurer to pay. Many families never ask, and so never find out.
"My mother's cancer counts as my pre-existing disease."
A relative's illness is family history, not your diagnosis. A form can ask about it, and you should answer honestly, but it is not an illness you have.
"I need a lawyer to go to the ombudsman."
You do not. The ombudsman process is free and designed for ordinary policyholders to use themselves, in plain language, with their own documents.
"An insurer can use non-disclosure against me forever."
After five years of unbroken health cover, non-disclosure cannot be used to refuse a claim unless the insurer proves fraud. This is why renewing without a break matters so much.
Questions we are asked
Common questions about pre-existing disease refusals
Is a gene fault a pre-existing disease?
Medically, no. A fault found in someone who has never had cancer is a statement about risk, not a diagnosis. The regulator's definition is built around diagnoses, advice and treatment. Whether a form asked about genetic tests, and how you answered, can still affect how an insurer treats it.
Can an insurer refuse my claim because my parent had cancer?
Not simply because of that. A parent's cancer is family history, not your illness. If the form asked about family history and you answered honestly, that answer should not become a reason to refuse. Ask for the exact clause in writing if an insurer suggests otherwise.
I had my test after buying the policy. Can they still refuse?
If the test was done after the policy began, there was nothing to disclose when you signed. The definition looks at diagnoses and advice before the start date. Keep the dated report and the policy schedule together, since they show the order of events clearly.
How long do I have to challenge a rejection?
Act quickly. The insurer's grievance process, the ombudsman and the consumer commission each have their own time limits, and some are strict. Write your grievance as soon as the refusal arrives, and note the date of every letter you send and receive.
What is the moratorium period?
It is the point after which a health policy can no longer be reopened over what you did or did not disclose. It arrives after five years of unbroken cover. The one exception is fraud that the insurer can prove.
Can the ombudsman help with a genetic dispute?
Yes. The ombudsman hears disputes about refused claims, including those on pre-existing disease grounds, and charges nothing. You usually need to have complained to the insurer first. The Hyderabad office covers Telangana and Andhra Pradesh.
Should I change insurers if I carry a fault?
Think carefully first. A new policy can bring new waiting periods and new questions. Portability carries over credit for time served, but the new insurer still assesses you. Many families are better protected staying with a policy they have renewed without a break.
Who can help me read a refusal letter?
A lawyer, a consumer organisation or the ombudsman's office can read it with you. For the medical side, such as whether a report shows illness or only risk, your oncologist or genetic counsellor can explain it plainly. Call the CION helpline if you are not sure who to approach.
