Why health claims get rejected — non-disclosure and how to declare right
Bishan Kumar Agarwal
The number-one reason health claims get repudiated in India is non-disclosure. Not fraud. Not exclusion. Not a technicality in the claim form. Non-disclosure of something that, declared at the time of application, would not have changed the outcome — except that hiding it broke the contract.
This is painful to see up close. A family at a difficult moment, a claim they expected to be straightforward, and then a repudiation letter citing a medical history item from six years ago. We have seen it many times. Almost every case was avoidable.
Non-disclosure: the cause behind most repudiations
Health insurance in India operates on a legal principle called “utmost good faith” — or uberrima fides in the policy documents. The insurer prices your risk based on what you tell them at the time of application. You have the complete picture of your health; they don't. The contract assumes you will share it honestly.
When you don't — even if the omission was accidental — you have altered the terms under which the insurer agreed to cover you. That is the basis for repudiation. The insurer is not saying you lied. They are saying the contract was formed on incomplete information, and they did not agree to cover the risk they were not told about.
Material non-disclosure vs immaterial omission
Not every omission matters equally. The relevant test is whether the omitted information was “material” — meaning whether a prudent insurer would have used it to decide whether to offer cover, at what premium, and with what exclusions.
- Material: hypertension, diabetes, a previous cardiac event, a resolved tumour, regular prescription medications, hospitalisations in the past 5 years
- Likely material: family history of cardiac disease or cancer (first-degree relatives), a prior insurance application that was declined or loaded
- Borderline: a childhood illness fully resolved 20+ years ago; minor seasonal allergies not requiring ongoing treatment
- Immaterial: a cold two years ago; a minor injury that did not require hospitalisation
When in doubt, declare it. The cost of a loading is far lower than the cost of a repudiated claim.
The form asks about diabetes. You take metformin. You think ‘I'm not really diabetic.' The insurer thinks you lied. The claim is gone.
This exact scenario plays out regularly. A client with “borderline” blood sugar, managing it with diet and a low-dose oral medication, does not tick the “diabetes” box on the proposal form. Years later, a hospitalisation linked to metabolic complications — the prescription record surfaces, the medication is unambiguously for diabetes management, the claim is denied.
The 8-year rule (and what it doesn't protect)
IRDAI regulations include a claim incontestability provision: after 8 continuous years of the same policy without a lapse, the insurer cannot repudiate a claim on the grounds of non-disclosure.
This is an important protection — eventually. It is not protection on the first claim, or the second, or in the first few years of a policy. And it has limits:
- The 8-year clock resets if the policy lapses, even briefly
- It does not protect claims on conditions that were explicitly excluded at inception
- It does not protect cases where the insurer can demonstrate intentional fraud
- Group-to-individual port does not carry the 8-year count
The 8-year rule is a long-term safety net. Do not rely on it as a declaration strategy.
How to declare correctly when you don't remember everything
Most people do not have their complete medical history memorised. That is normal. The way to approach a proposal form is not from memory — it is from records.
Before filling in any health insurance proposal form, compile this list:
- Current prescription medications (name, dose, duration)
- Last three specialist consultations and why you went
- Last three diagnostic tests and what they showed
- Any surgeries or hospitalisations in the past 5 years
- Any insurance applications in the past 3 years — accepted, declined, or loaded
- First-degree family history: cardiac disease, cancer, diabetes, kidney disease
Review this list at every renewal too. Health changes. A condition you didn't have at inception may have emerged, and a declaration update protects you going forward. If you're unsure whether something is material, ask your advisor. The answer is almost always “declare it and let the insurer decide.”
Insurance is a contract between you and the insurer. This article is general information only — speak to a licensed advisor about your specific situation before making decisions.
Family history — always declare it
Genetic conditions and family history of cardiac disease, cancer, or diabetes are material to underwriting. Omitting them is non-disclosure, even if you personally don't have the condition.
Past hospitalisation, even minor — declare it
‘Forgotten’ admissions have a habit of resurfacing in hospital records during claim verification. A day-care procedure five years ago still counts.
Past applications declined — declare it
Insurers share underwriting data. If a prior application was declined or loaded, you must declare it. Concealing it is treated as intentional non-disclosure.
Recreational substance use — declare it
Repudiations on undisclosed alcohol or tobacco use are routine. If the claim involves a condition linked to substance use, the insurer will look at the declaration form.
Mental health history — declare it
Even resolved episodes of depression, anxiety, or other mental health conditions are material. IRDAI guidelines now require coverage for mental health, but non-disclosure of history is still a repudiation ground.
49-year-old male, stent procedure, hypertension undeclared.
49-year-old salaried professional. Had been managing hypertension with telmisartan 40mg for eight years before buying the policy.
Filed a claim for a coronary stent procedure after a cardiac event. Insurer pulled pharmacy records during verification and found the eight-year prescription history. Claim repudiated on grounds of non-disclosure. Amount: ₹4.5L.
Reviewed the case file, identified that the condition was genuinely under control and the client had assumed ‘managed hypertension’ was not material. Filed an appeal with supporting clinical notes and cardiologist letters arguing it was an inadvertent omission.
Settled for 40% reimbursement after 14 months of appeal. ₹2.7L recovered. Avoidable — full declaration at the time of application would have resulted in a loading, not a repudiation.

- What if I forgot about a condition I had 10 years ago?
- Genuinely forgotten conditions can be the basis for an appeal if repudiated. Courts and the Insurance Ombudsman have ruled in favour of policyholders where the omission was demonstrated to be inadvertent and the condition was truly resolved. That said, the burden is on you to prove inadvertence — which is hard. Best practice: keep a health diary and review it at every application.
- Can the insurer call my doctor?
- Yes. During claim verification, insurers can request medical records from hospitals and treating physicians. They can also access diagnostic lab records. This is standard practice and the policy document authorises it.
- Does the 8-year rule cover everything?
- No. After 8 continuous policy years, an insurer cannot repudiate a claim on non-disclosure grounds for conditions not excluded at inception. However, the rule does not protect you from repudiation if the non-disclosure was intentional fraud, and it does not apply to benefits that were explicitly excluded at the time of policy issuance.
- What's the time limit to submit a claim after discharge?
- Most plans require claim intimation within 24 hours of hospitalisation (or immediately for planned admissions). The final claim documents typically have a 15–30 day submission window after discharge. Missing these timelines is a separate ground for claim rejection — check your policy schedule.
