Claim Pitfalls, Complaints and Official Sources
Non-disclosure in health insurance and the 5-year moratorium: what protects you
How non-disclosure of pre-existing conditions affects health claims in India, what the 60-month moratorium protects, what it does not, and how to correct a proposal form.
If you did not declare a condition in your health insurance proposal form, the insurer can reject a related claim and may cancel the policy for non-disclosure or misrepresentation, but only within the first 60 continuous months of cover. After that moratorium period, IRDAI's rules say no policy or claim can be contested on grounds of non-disclosure or misrepresentation, except for established fraud. The moratorium was reduced from 8 years to 5 years under the IRDAI changes of 2024. Within the first five years, the strongest protection is a complete proposal form. If you realise you missed something, tell the insurer in writing now, before a claim.
This guide is part of the overview of health insurance claim rejection reasons.
What counts as non-disclosure
- Not declaring a condition diagnosed or treated in the look-back period (36 months before the policy under the current PED definition) when the form asked about it
- Answering "no" to questions about regular medicines, past surgeries or hospital admissions when the answer was "yes"
- Not disclosing tobacco or alcohol use where the form asked
- Not disclosing other health policies held
The question is what the form asked and what you knew. An undiagnosed condition you were unaware of is not a non-disclosure, although it may still fall under the definition of pre-existing disease if signs or symptoms meant a doctor would have diagnosed it.
What the moratorium does and does not do
| Moratorium protects against | Moratorium does not override |
|---|---|
| Rejection for non-disclosure of a pre-existing condition | Established fraud |
| Rejection for misrepresentation in the proposal form | Policy exclusions (e.g. cosmetic treatment) |
| Cancellation of the policy on those grounds | Sub-limits, co-pays, deductibles in the contract |
| Medical necessity and the hospital definition | |
| Sum insured limits |
The 60 months are counted on continuous cover, including time with a previous insurer if you ported. For a sum insured increase, the moratorium on the increase starts from the date of the increase.
Worked example: inside and outside the moratorium
Illustrative. Pradeep bought a policy on 1 August 2022 and did not declare thyroid medication he had been taking since 2020.
| Claim | Date | Policy year | What can happen |
|---|---|---|---|
| Thyroid surgery | March 2025 | Year 3 | Insurer can examine records; if it finds the undeclared medication, it can reject and may cancel the policy |
| Unrelated appendicitis | March 2025 | Year 3 | Should be payable on its merits; but if the insurer cancels for non-disclosure, cover ends |
| Thyroid surgery | September 2027 | Year 6 | After 60 months (1 August 2027), cannot be contested for non-disclosure; still subject to other terms |
Because the moratorium was shortened to 60 months, Pradeep reached it in August 2027 instead of 2030.
If you realise you missed something
- Write to the insurer now, stating the condition, when it was diagnosed and the treatment, with reports.
- The insurer may accept it without change, apply a waiting period for that condition (within the 36-month cap), add a loading, or, in some cases, decline to continue on the original terms. It must respond in writing.
- Keep the correspondence with your policy documents.
Disclosing late is far better than discovering the problem at claim time. Agents sometimes advise customers not to mention "minor" conditions; that advice is wrong and the risk is yours.
If a claim is rejected for non-disclosure
- Ask for the evidence: which document shows the condition, and its date.
- Check the dates: was the condition diagnosed before the look-back period? Was it actually diagnosed, or only a symptom?
- Check what the form asked. Vague or general questions are construed against the insurer in many Ombudsman decisions; this depends on the facts.
- Check whether the moratorium had been reached, counting ported years.
- Ask the treating doctor to clarify, in writing, when the condition began if the insurer has read the history wrongly.
- Escalate through the grievance officer, Bima Bharosa and the Ombudsman. See complaints and the Ombudsman.
The discharge summary trap
Hospitals often write "known case of hypertension for 5 years" in the history section of the discharge summary. If your policy is 2 years old and hypertension was not declared, this line alone can lead to a query. If the history is wrong, ask the treating doctor to correct it with an explanatory note before submitting. Do not ask a doctor to alter a true record; that would itself be misrepresentation.

Frequently asked questions
Does the moratorium apply to policies bought before 2024?
The 60-month moratorium applies under current product rules; for a policy you have held for years, check your latest wording or ask the insurer in writing which moratorium period applies.
Can the insurer refuse to renew after I disclose a condition?
Renewal cannot be refused on the ground that you claimed or disclosed a condition, except where the rules allow (for example fraud or withdrawal of a product with migration offered). The insurer can apply terms permitted by its underwriting for the newly disclosed condition.
Is a family history of illness a pre-existing condition?
No. Pre-existing disease concerns the insured person's own conditions. Answer family history questions only if the form asks them.
