Non-Disclosure Health Insurance Claim Rejection: What Insurers Must Prove

Non-disclosure rejection means the insurer says you hid a material fact at the proposal stage. The insurer must prove four things together, the fact was material, the fact was within your knowledge, the omission was deliberate, and the policy was contested within 2 years of issue. If any one of these fails, the rejection is on weak ground and you can fight it.

• “Non-disclosure” means you did not mention something on the proposal form that the insurer says you should have mentioned.
• “Material fact” means something that would have changed the insurer's underwriting decision, the premium it charged, or the cover it offered.
• “Misrepresentation” is an inadvertent error or an honest mistake on the form.
• “Suppression” is the deliberate hiding of a fact you actually knew was relevant.
• Section 45 of the Insurance Act 1938 protects you after 2 years from policy issue. After that window, the burden of proving fraud sits on the insurer, not on you.
• The IRDAI Master Circular on Health Insurance Business dated 29 May 2024 adds an 8-year moratorium beyond Section 45. After 8 continuous renewals, a claim can be contested only on proved fraud.

The single biggest thing to grasp is this. A rejection letter that simply says “non-disclosure” is not the end of the story. It is a starting position by the insurer. The law puts a heavy load on the insurer to back that position with evidence. Most citizens never demand that evidence and that is exactly why rejections stick.

For a non-disclosure rejection to stand in law, the insurer must prove all four of the following together.

1. The omission concerns a material fact. The fact must be one that, if disclosed, would have changed underwriting. Trivial omissions do not count.
2. The fact was within your knowledge at proposal stage. You cannot non-disclose what you did not know. A diagnosis you only received after the policy was issued cannot be back-dated to the proposal form.
3. The non-disclosure was deliberate. Innocent or inadvertent omission is not enough. The insurer must show intent to deceive.
4. The contest is within 2 years of policy issue. Beyond 2 years, Section 45 of the Insurance Act 1938 shifts the burden to the insurer and adds a fraud-only standard.

If any one of these fails, the rejection is on weak ground. Your reply letter should attack each ingredient in turn and ask the insurer to prove it.

The line between a defensible mistake and a valid suppression decides the entire dispute. Use this table when you draft your reply.

The line is intent plus materiality. Courts have consistently held that innocent omission is not enough to reject. Read the Supreme Court ruling in Sulbha Prakash Motegaonkar v LIC 2015 for the cleanest statement of that principle.

• The insurer's entire case rests on a specific question in the proposal form and your specific answer to it. Without that question-answer pair on paper, the insurer has nothing.
• If the question was vague or compound (for example “Have you ever had any disease, disorder or treatment?”), any ambiguity is read in your favour. This is the rule of contra proferentem. The drafter of the contract bears the cost of unclear language.
• If your agent filled the form on your behalf and ticked the wrong boxes, you are not bound by his errors. The National Consumer Disputes Redressal Commission has held in multiple cases that the agent is the insurer's representative, and his lapses are the insurer's liability.
• Most importantly, demand a copy of the proposal form with your signed declaration. A surprising number of citizens have never seen what was actually submitted on their behalf. The form is the foundation of the rejection and you have a right to inspect it.

1. Get the rejection letter in writing. If only a phone call or SMS was received, demand a formal letter on insurer letterhead with a reasoned ground.
2. Demand a copy of the proposal form and the signed declaration as on file.
3. Demand the specific question and your specific answer that the insurer says was wrong.
4. Demand the medical record the insurer is relying on, with date and doctor's name.
5. Count time from policy issue. If 2 or more years have passed, Section 45 of the Insurance Act 1938 applies.
6. Count renewals. If 8 or more continuous renewals, the IRDAI Master Circular 2024 moratorium applies.
7. Email the grievance officer of the insurer using the reply template below.
8. File a complaint at IRDAI Bima Bharosa if no reasoned reply arrives in 15 working days.

• “Send the proposal form plus signed declaration as on file.”
• “Identify the specific question and the specific answer that the insurer says is non-disclosure.”
• “Send the medical record the insurer relies on.”
• “Prove that the omitted fact was within my knowledge at proposal stage.”
• “Confirm whether the contest is within 2 years from policy issue per Section 45 of the Insurance Act 1938.”
• “Confirm whether the IRDAI Master Circular dated 29 May 2024 moratorium provision applies, given the number of continuous renewals.”
• “Confirm whether the insurer's position is that the omission was deliberate or merely inadvertent, with the evidence relied on.”

These questions are framed so that any honest reply forces the insurer to either back the rejection with evidence or quietly settle the claim. In a large share of disputes, the second outcome is the one that follows.

Dear Sir / Madam,

I refer to the rejection of my health insurance claim citing non-disclosure. I deny the rejection and request the following within 15 working days.

1. A copy of the proposal form plus signed declaration on file with the insurer.
2. The SPECIFIC question and my SPECIFIC answer that the insurer says is non-disclosure.
3. The medical record the insurer relies on.
4. Proof that the omitted fact was within my knowledge at proposal stage.
5. Confirmation whether the contest is within 2 years from policy issue per Section 45 of the Insurance Act 1938.
6. Confirmation whether the IRDAI Master Circular dated 29 May 2024 moratorium provision applies, given [N] completed renewals.

I rely on the following.

a. Section 45 of the Insurance Act 1938 which shifts the burden of proving deliberate suppression of a material fact onto the insurer after 2 years from policy issue.
b. IRDAI Master Circular on Health Insurance Business dated 29 May 2024 paragraph on moratorium which bars contestation of a claim after 8 continuous renewals except in proved fraud.
c. Supreme Court in Branch Manager, Bajaj Allianz v Saurabh Prakash 2006 where the court held that a material fact must be in policyholder knowledge.
d. Supreme Court in Sulbha Prakash Motegaonkar v LIC 2015 where the court held that inadvertent omission is not material non-disclosure.
e. Supreme Court in LIC v Asha Goel 2001 where the court held that even after 2 years, fraud must be proved with material evidence.

If a reasoned reply does not arrive in 15 working days, I shall file at IRDAI Bima Bharosa and Insurance Ombudsman.

Regards,
[Your Name]

This template puts six clear questions and five legal anchors on the table in one short letter. The insurer must address each point or its reply is itself a ground for escalation. Keep a copy and a delivery proof for every channel used.

These are the eight most common insurer claims and the standard counter that defeats each in correspondence.

• “Hospital admission form says condition was 5 years old.” Admission forms are written under stress, often by a relative, and are not contemporaneous medical evidence. Without a prescription or signed physician note dated before policy issue, the admission form alone fails the materiality test.
• “The patient's son confirmed verbally on the phone.” Verbal hearsay is not material non-disclosure. The insurer must produce a written record signed by the policyholder.
• “Routine medical record shows BP 140 / 95.” A single elevated reading is not a diagnosis. Hypertension is a diagnosed condition, not a stray data point.
• “Family history is non-disclosure.” Family history is not personal non-disclosure unless you yourself had been diagnosed with that condition.
• “Online medical record search shows past visits.” A pharmacy visit or out-patient consult is not a diagnosis. The insurer must show contemporaneous policyholder knowledge of a specific material condition.
• “Proposal form was filled by the agent.” Agent error is the insurer's responsibility. Multiple NCDRC decisions place the agent inside the insurer's circle, not yours.
• “Proposal question was vague.” Ambiguity is read in favour of the policyholder under the contra proferentem rule.
• “Contest within 2 years means automatic rejection.” This is wrong. Even within 2 years, the insurer must still prove materiality plus intent. Section 45 only changes the burden, it does not lower the standard.

• No reasoned reply in 15 working days after your grievance email.
• Insurer cannot produce the proposal form or the signed declaration.
• Insurer cannot identify the specific question plus answer.
• Insurer relies on hearsay or a vague “family history” statement alone.
• Insurer ignores the IRDAI moratorium or Section 45 references in your letter.
• Insurer relies only on a stray lab value or single reading without a doctor's diagnosis.

Any of these is enough to escalate. The next step in each case is the same. File at IRDAI Bima Bharosa, then the Insurance Ombudsman, then the consumer court.

Complaint route:

Insurer Grievance Officer (15 working days) ⇒ IRDAI Bima Bharosa (15 working days) ⇒ Insurance Ombudsman (30-day SLA, free, claims up to ₹50 lakh, binding on insurer) ⇒ Consumer court via edaakhil or consumer court.

Use the IRDAI policyholder portal for status checks and the IRDAI IGMS dashboard for older complaints. The IRDAI toll-free numbers are 155255 and 1800-4254-732. The Ombudsman procedure is described in detail at the cioins procedure page. The IRDAI grievance redressal mechanism is summarised at the IRDAI grievance redressal page.

• Accepting verbal explanations from the TPA call centre. Always demand a written reasoned ground.
• Not demanding the proposal form copy. The entire rejection rests on it.
• Citing only “fairness” or “I have paid the premium for years” instead of pointing to Section 45 plus the IRDAI 8-year moratorium.
• Forgetting that an agent-filled form shifts the burden to the insurer.
• Missing the 1-year Insurance Ombudsman limitation window. The clock starts from the insurer's final reply.
• Replying only to the TPA email and not copying the insurer grievance officer. The TPA cannot reverse a rejection on its own.
• Quoting case law without the citation. Always add the case name plus year so the reply is on record correctly.

A non-disclosure rejection is not just a denial of one claim. It also flags your policy as voidable. If you accept the rejection without a fight, the same insurer or its TPA can rely on the same reading at the next renewal or the next claim. Even worse, the rejection may be reported under industry-wide data sharing arrangements, leading to higher premiums or refusals when you shop for a new policy.

This is the reason to put the four-ingredient test, Section 45 reference and IRDAI 8-year moratorium in writing on day one. Even if you eventually settle on a partial payout, the written reply means the insurer cannot quietly mark you as a fraud risk. The paper trail also feeds directly into the Ombudsman complaint if escalation becomes necessary.

The Indian insurance contract is built on a principle called uberrima fides, meaning utmost good faith. This goes both ways. You are expected to disclose what you actually know to be material, and the insurer is expected to ask clear specific questions and to underwrite carefully. The law balances the duty by allocating the burden of proof.

• Within the first 2 years of policy issue, the insurer can question disclosures more easily. Even here, the insurer must still produce evidence. A bare allegation is not enough.
• Beyond 2 years, the burden shifts decisively under Section 45 of the Insurance Act 1938. The insurer must now prove fraud with material evidence. This is a high bar, much higher than ordinary non-disclosure.
• Beyond 8 continuous renewals, the IRDAI moratorium freezes contestation altogether except in proved fraud. This is the safest stage of policy life.

A reply letter that names the exact stage of the policy and quotes the right statute defeats most boilerplate rejections. The insurer's grievance officer reads the law just as you do. Once your letter is on file, the rejection is no longer a one-sided decision. It is a contested claim that the insurer must defend at the Ombudsman if it does not settle.

Many disputes start because the proposal form asks questions like “have you ever consulted a doctor for any disease, disorder or treatment?”. Read literally, almost every adult would answer yes, since a routine fever consultation is technically a consultation. The law saves the citizen here. A question that is so broad that it captures harmless events is read narrowly. Only material conditions, with a written diagnosis or treatment plan, count for non-disclosure.

If your rejection letter quotes such a vague question, your reply should specifically argue that the question is overbroad and that any reasonable reading of your answer was correct. Pair this argument with the contra proferentem rule. The insurer drafted the form. The cost of vague drafting falls on the insurer, not on you.

Non-disclosure means failing to mention a material fact on the proposal form at the time of buying or renewing the policy. The insurer says the omission was relevant to its underwriting decision. Only deliberate, knowing omissions of material facts count. Honest mistakes and trivial omissions are not non-disclosure.

The insurer must prove four things together. First, the fact was material. Second, the fact was within your knowledge at proposal stage. Third, the omission was deliberate. Fourth, the contest is within 2 years of policy issue. If any one fails, the rejection is weak. Demand evidence on each ingredient in writing.

A mistake is an honest or inadvertent omission such as forgetting a single high reading from years ago, or an agent filling a form incorrectly. A deliberate suppression is hiding a fact you knew was relevant, for example concealing a heart attack from 6 months back. The line is intent plus materiality.

Yes. Section 45 of the Insurance Act 1938 places a strict burden on the insurer once the policy has run for 2 years from issue. After the 2-year mark, the insurer must prove fraud with material evidence. A mere allegation of non-disclosure is not enough to void the policy beyond this window.

The IRDAI Master Circular on Health Insurance Business dated 29 May 2024 includes a moratorium clause. After 8 continuous policy years (counted from the first renewal), the insurer cannot contest a claim or void the policy except on proved fraud. This is a powerful second layer of protection beyond Section 45.

No. If your agent filled the proposal form on your behalf and made errors, the insurer carries the liability. Indian consumer forums and the NCDRC have ruled in multiple cases that the agent is the insurer's representative. Demand the original signed proposal form and point to the agent's role in your reply letter.

Not on its own. Family history is the health record of your parents and siblings. It is not your personal medical record. Unless you yourself had been diagnosed with the same condition, the insurer cannot reject a claim solely on the basis of family history that was not asked or was not answered fully.

No. Hospital admission forms are filled in haste, often by a relative, and are not contemporaneous medical evidence of past disease. The insurer must produce a doctor's prescription, signed physician note or diagnostic report from before the policy was bought to back its position.

A vague or compound proposal question (for example, “have you ever had any disease or disorder?”) is read in favour of the policyholder. This rule is called contra proferentem. The drafter of the contract bears the cost of unclear language. Quote this rule in your reply letter.

Yes. The Insurance Ombudsman is free to approach. There is no court fee or filing fee. The Ombudsman handles claims up to ₹50 lakh and the award is binding on the insurer but not on the policyholder. The SLA is 30 days from receipt of the complaint. File online at the cioins complaint portal.

Yes. The Ombudsman is one route. You can also file a direct consumer complaint via edaakhil or in person at the District Commission. The consumer route allows compensation for mental agony in addition to the claim amount. Choose Ombudsman for speed and consumer court for compensation depth.
