Critical Illness Insurance Claim Rejected for Non-Disclosure? Here Is How to Fight It

Who this guide is for

This guide is for anyone whose critical illness, health, or related medical insurance claim has been rejected on the ground of "non-disclosure" or "suppression of material facts", typically about a pre-existing condition or earlier medical history. It is useful if you:

• Received a repudiation letter saying you did not disclose a pre-existing disease, an earlier diagnosis, or past treatment, or
• Believe the condition was diagnosed only after you bought the policy, or
• Think the proposal form never actually asked about the condition the insurer is now relying on, or
• Suspect an agent filled the form for you and ticked answers you never gave.

It applies to policies from private insurers, from LIC, and from the public-sector general insurance companies. The complaint route is broadly the same; only the RTI angle differs, because RTI reaches public-sector insurers but not private ones.

Who this guide is NOT for

This guide does not cover claims rejected purely on a waiting-period ground with no non-disclosure allegation, claims rejected for a clear policy exclusion, or disputes where large sums and complex medical evidence are involved and you may need a lawyer or a qualified insurance professional. It also does not give medical advice about your illness. Where the amount at stake is large, or the insurer alleges fraud, consider professional help before you sign any settlement. For a closely related situation, see our guide on a health insurance pre-existing disease claim rejection appeal.

What you can do this weekend

Friday evening

Collect every document the insurer has given you. Find the repudiation or rejection letter and read the exact reason. Note whether it cites non-disclosure of a pre-existing disease, a waiting period, or both. Then dig out your policy document, the premium receipts, and any copy of the proposal form. Search your email and the insurer's app for the policy schedule and claim communications. Write down two key dates: the policy start date and the date your illness was first diagnosed. These two dates decide most non-disclosure disputes.

Saturday

Send a written request to the insurer for the documents you do not have: the signed proposal form, the full policy wording, the detailed repudiation letter, and any pre-policy medical report. Use email so you have a timestamp. The proposal form is the heart of your case, because non-disclosure is judged only against the questions that were actually asked. Then visit or call your treating doctor or hospital and ask for a dated certificate stating exactly when your illness was first diagnosed, plus copies of the first prescription and the first test report.

Sunday

Build your timeline. On one page, list the policy start date, every relevant doctor visit, every diagnosis date, and the claim and rejection dates. Place the proposal form questions next to what you actually knew on the day you signed. If a question was never asked, or your illness came later, highlight it. Draft your internal appeal to the insurer using the template below. Keep one folder, clearly named by date, with scans of everything. By Monday you will be ready to send the appeal and start the grievance clock.

Documents and evidence checklist

Step-by-step action plan

Step 1 — Get the proposal form and read the exact rejection ground

Ask the insurer in writing for the signed proposal form, the full policy wording, and the detailed repudiation letter. The proposal form decides the case, because non-disclosure is measured only against the questions that were actually put to you. Read the rejection letter carefully and identify the precise ground. Is it non-disclosure of a pre-existing disease? A specific waiting period? Or both grounds combined? If the letter is vague or mixes grounds, ask the insurer to state in writing the single, specific reason and the exact proposal-form answer it relies on.

Step 2 — Compare what was asked against what you knew

Place the proposal form questions next to what you actually knew on the date you signed. Non-disclosure needs a question that was asked and a material fact you knew and did not reveal. If the form never asked about the condition the insurer now cites, there is nothing you failed to disclose. If an agent filled the form and ticked answers you never gave, note that, because you are entitled to a form that reflects your true answers. Mark each disputed answer clearly; these become the spine of your appeal.

Step 3 — Pin down the date of first diagnosis

Get a dated certificate from your treating doctor stating exactly when your illness was first diagnosed, along with the first prescription and first test report. A pre-existing condition is one that existed before the policy. If your first diagnosis date falls after the policy start date, the illness cannot be a hidden pre-existing disease. If the diagnosis was earlier but you genuinely did not know, or the form did not ask, say so plainly. The diagnosis date is often the single fact that turns a rejection around.

Step 4 — Check the waiting period separately

Read your policy schedule for the waiting periods that apply: the initial waiting period, the longer pre-existing-disease waiting period, and any illness-specific waiting periods. The exact lengths vary by policy and insurer, so rely on your own document, not a general number. A waiting-period rejection is a different argument from non-disclosure. If the insurer relies on a waiting period, your rebuttal is about dates and policy terms; if it relies on non-disclosure, your rebuttal is about the proposal form. Do not let the two be blurred together.

Step 5 — File the insurer's internal appeal and grievance

Write a clear, dated appeal to the insurer's claims team, and copy the grievance officer. Attach your timeline, the doctor's certificate, and the proposal-form comparison. State the specific ground you are rebutting and the evidence for it. Ask for a written, reasoned decision within the insurer's stated grievance timeline. Keep the acknowledgement. This internal grievance step is important, because the IRDAI Bima Bharosa portal and the Insurance Ombudsman both expect you to have approached the insurer first. Use the copy-paste template below.

Step 6 — Escalate to IRDAI Bima Bharosa, then the Ombudsman

If the insurer rejects your appeal or does not reply in time, register your complaint on the IRDAI Bima Bharosa portal at bimabharosa.irdai.gov.in. This is the regulator's grievance system for all insurers, private and public. If that does not resolve it, approach the Insurance Ombudsman for your area, which decides insurance disputes up to a prescribed value and is free to use. Carry your full paper trail.

When RTI can help

The RTI Act, 2005 applies to public authorities. The Life Insurance Corporation of India (LIC) and the public-sector general insurance companies are public authorities under the Act, because they are owned or controlled by the Central Government. If your rejected policy is with one of these insurers, you can file an RTI application with its Public Information Officer to:

• Obtain the notings and internal assessment on your claim file that led to the repudiation.
• Find out the exact proposal-form answer and material fact the insurer says you did not disclose.
• Ask whether a pre-policy medical examination was conducted and what it recorded.
• Confirm the date your claim was received and the dates of each step taken on it.

The IRDAI is also a public authority under the RTI Act. You can file an RTI with the IRDAI's Central Public Information Officer to confirm whether your complaint registered on the Bima Bharosa portal has been received, and to ask about the status of action taken on it. Read our full guide on how to file an RTI online for the step-by-step process, and see how to file a first appeal if the insurer's PIO does not respond within the prescribed time. An RTI to a public-sector insurer creates a formal paper trail that can be used in your Ombudsman complaint.

When RTI will not help

Private insurers: Private life and general insurance companies are not public authorities under the RTI Act. You cannot file an RTI directly against them. For a private insurer, the correct route is the insurer's own grievance officer, then the IRDAI Bima Bharosa portal at bimabharosa.irdai.gov.in, and then the Insurance Ombudsman. You can, however, file an RTI with the IRDAI asking about the action taken on your complaint, because the regulator is a public authority.

What RTI cannot do: RTI gives you information; it does not order an insurer to pay your claim. The documents you obtain, such as the claim-file notings or proof that no pre-policy issue was flagged, are evidence you can use in your appeal, before the Ombudsman, or in a consumer forum. The decision to admit or reject the claim still comes through the grievance and Ombudsman process, not through RTI itself.

Common mistakes to avoid

• Not getting the signed proposal form. This is the most common mistake. Non-disclosure is judged only against the questions actually asked. Without the proposal form, you are arguing blind. Always request it in writing before you draft your appeal.
• Confusing a waiting-period rejection with a non-disclosure rejection. These need different rebuttals. A waiting-period dispute is about dates and policy terms; non-disclosure is about the proposal form. Ask the insurer to state the single specific ground in writing.
• Not fixing the date of first diagnosis with documents. A verbal claim that "it started later" is not enough. Get a dated doctor's certificate, the first prescription, and the first test report. The diagnosis date often decides the case.
• Letting an agent's mistakes go unchallenged. If an agent filled your proposal form and ticked answers you never gave, say so clearly and in writing. You are entitled to a form that reflects your true answers.
• Skipping the insurer's internal grievance. Both the IRDAI Bima Bharosa portal and the Insurance Ombudsman expect you to have approached the insurer first. Keep the acknowledgement of your internal appeal.
• Filing an RTI against a private insurer. Private insurers are not covered by the RTI Act. Use the grievance, Bima Bharosa, and Ombudsman route instead. RTI only reaches LIC, public-sector general insurers, and the IRDAI.
• Accepting a low settlement under pressure without checking your options. Where the amount is large or fraud is alleged, get advice from a qualified professional before signing anything.
