Health Insurance
Pre-Existing Disease (PED)
A Pre-Existing Disease (PED) is any condition, illness, injury, or related diagnosis that the insured person had — or had received treatment or advice for — within a defined window before the policy was issued. The IRDAI's standard definition, used uniformly across Indian health insurers from the 2020 product harmonisation, is any condition for which signs or symptoms existed, or for which medical advice or treatment was received, within 48 months prior to the policy's first issue date. Common examples include diabetes, hypertension, asthma, thyroid disorders, prior cardiac events, and any cancer diagnosis.
The PED disclosure on the proposal form is one of the most consequential entries the buyer makes — undisclosed PEDs are a leading cause of claim disputes at hospitalisation. Indian health policies typically apply a PED waiting period of 24 to 48 months from inception, during which any hospitalisation directly arising from the disclosed PED is excluded from cover. From October 2024, IRDAI capped the maximum PED waiting period at 36 months across the industry, down from the older 48-month ceiling.
Worked example: Sunita, 42, discloses type 2 diabetes diagnosed in 2019 when buying a ₹10 lakh health policy in May 2025. The policy issues with a 36-month PED clause; any diabetes-related hospitalisation (a diabetic foot ulcer admission, a diabetic ketoacidosis admission) is excluded until May 2028, while an unrelated dengue admission in August 2025 is payable after the standard 30-day initial waiting. A common misconception is that 'I am young and healthy, so the PED clause does not concern me'.
Many young buyers carry undiagnosed conditions — borderline blood pressure, fatty liver, mild thyroid abnormality — that surface only when a routine medical for a job or a loan order shows the result. Disclosing voluntarily even if uncertain is the safer path; insurers view 'disclosed but not yet a diagnosis' more favourably than a discovery years later. Another common misconception is that switching insurers resets the PED clock.
Under IRDAI's portability rules, the time already served on a PED clause is carried forward when you port — if you served 30 months of a 36-month wait on Insurer A and port to Insurer B, you serve only the remaining 6 months on the new policy. Lapse the policy and rebuy, and the clock starts over. Related: waiting-period, portability, proposal-form.
