Pre-Existing Disease Disclosure
What counts as a pre-existing disease, why it has to be disclosed in the proposal form, what an insurer may do with a disclosed condition, the consequences of hiding one, and the 60-month moratorium that limits later disputes.
What a pre-existing disease is
A pre-existing disease (PED) is a condition, ailment, injury or disease that was diagnosed by a physician, or for which medical advice or treatment was recommended or received, within the look-back period before the policy began or was reinstated. Under IRDAI's current standard definition the look-back is 36 months.
Diabetes kept under control with daily medicine is a PED. Any condition under medication or treatment has to be declared, however well controlled it is.
Disclosure and what follows from it
The proposal form must disclose such conditions fully and truthfully. This is the duty of utmost good faith at work: the insurer prices and accepts the risk on what it is told, and a pre-existing condition is a material fact.
Disclosure has a cost that is visible at the start. Depending on the insurer, a disclosed condition may lead to a premium loading, a waiting period for that condition or an exclusion. In return, the position of the condition under the policy is settled from the start. A disclosed PED is covered once the PED waiting period stated in the policy has been served, and that period cannot exceed 36 months under current IRDAI rules. After that the condition is treated like any other illness.
What happens when a condition is hidden
Non-disclosure of a PED is one of the most common reasons for claim disputes. Material non-disclosure can lead to the claim being rejected and to the policy being cancelled or not renewed, as the policy terms provide. The claim at stake is usually worth far more than any premium saved by staying silent.
Hidden conditions tend to surface at claim time. During claim investigation insurers examine pharmacy purchase records, previous hospital records, diagnostic reports and the treating doctor's statements to check the medical history.
An intermediary who helps a client conceal a PED commits a serious breach. A Point of Sales Person can face termination of the engagement, penalties and legal action, and the insurer or intermediary that appointed the POSP can face regulatory action.
The moratorium
The insurer's right to contest is limited in time. After 60 months of continuous cover, the moratorium period, a health policy or claim cannot be contested for non-disclosure or misrepresentation except where fraud is established. Cover carried over from a ported or migrated policy counts towards the 60 months. Before the 2024 rules the period was eight years.
This is a health-insurance rule. Section 45 of the Insurance Act, 1938, with its three-year limit, applies to life insurance and should not be confused with it.
Rules at a glance
The same condition, declared and undeclared
Illustration: Mohan, 46, of Jaipur has taken tablets for diabetes for two years when he proposes for a policy. If he declares it, the insurer may accept him with a loading or a waiting period for diabetes. Suppose his policy states a 36-month PED waiting period: from the fourth policy year a diabetes-related hospitalisation is payable like any other.
If he answers no to the question, the policy is issued without those terms. When he is hospitalised in the second year, the insurer's investigation finds two years of pharmacy bills and his doctor's notes. The claim can be rejected and the policy cancelled for non-disclosure.
The cost of disclosing against the cost of hiding
- Assumptions, for arithmetic only: base premium ₹20,000 a year; on disclosure the insurer applies a loading of 25% (an invented figure; loadings are set by each insurer); a hospitalisation costing ₹4,00,000 arises in the fourth policy year, after the waiting period.
- Loading = 25% × ₹20,000 = ₹5,000 a year.
- Extra premium paid over four years because of disclosure = 4 × ₹5,000 = ₹20,000.
- With disclosure: the ₹4,00,000 claim is assessed like any other. Without disclosure: the same claim is open to rejection, so up to ₹4,00,000 is at risk.
Result. Staying silent saves ₹20,000 of premium in this example and puts a ₹4,00,000 claim at risk. Disclosure costs more up front but protects the claim.
Key points
- A PED is a condition diagnosed, or for which advice or treatment was recommended or received, within 36 months before the policy began.
- Every such condition has to be disclosed in the proposal form, including one that is well controlled with medicine.
- A disclosed PED is covered after the policy's PED waiting period, which cannot exceed 36 months.
- Non-disclosure can lead to rejection of the claim and cancellation of the policy.
- After 60 continuous months, only established fraud allows a policy or claim to be contested.
Common misunderstandings
- A controlled condition is not exempt from disclosure: any condition under medication or treatment is a PED and has to be declared.
- Serving the waiting period does not cure non-disclosure: an undisclosed PED can still lead to rejection until the moratorium has run.
- The moratorium does not protect fraud: where fraud is established the policy or claim can be contested even after 60 months.
Questions people ask
When does cover for a disclosed PED begin?
Once the PED waiting period stated in the policy has been served. That period cannot exceed 36 months under current IRDAI rules.
Does time with a previous insurer count towards the 60 months?
Yes. Continuous cover carried over from a ported or migrated policy counts towards the moratorium period.
How would an insurer find out about an old prescription?
Claim investigations look at pharmacy records, earlier hospital records, diagnostic reports and the treating doctor's statements.
