What counts as a pre-existing disease (PED) in health insurance?

A pre-existing disease is any condition, ailment, injury or disease that a doctor diagnosed, or for which medical advice or treatment was recommended or received, within 36 months before your policy started. The definition turns on diagnosis and advice within that window, not on when you first felt unwell. A disclosed pre-existing disease can be excluded for a waiting period of at most 36 months of continuous cover.

This is the definition in IRDAI's 2024 Insurance Products Regulations. A condition is pre-existing if it was diagnosed by a physician not more than 36 months before the policy commenced, or if medical advice or treatment for it was recommended by, or received from, a physician in that period. The definition does not apply to overseas travel policies.^[1]

The two tests in the definition

• Diagnosed by a physician: The condition was diagnosed not more than 36 months before the policy commenced.^[1]
• Advice or treatment: Medical advice or treatment for it was recommended by, or received from, a physician in that same period — even without a formal diagnosis.^[1]

So the questions in a pre-existing disease dispute are factual: what was diagnosed or advised, by whom, and on what date. On the face of the definition, a symptom you never consulted a doctor about meets neither test, and a diagnosis made more than 36 months before the policy began does not meet the first test — though advice or treatment for the condition within the 36 months would still meet the second. Read the definition in your own policy, though — products not yet revised under the 2024 framework may word it differently.^{[1, 2]}

How a pre-existing disease affects your cover

A pre-existing disease that you disclosed can be excluded for a waiting period of at most 36 months of continuous coverage, and insurers may offer shorter periods. After sixty continuous months of cover, the insurer can no longer contest the policy or a claim on grounds of non-disclosure or misrepresentation, except established fraud.^[1]

Non-disclosure is a separate question from the waiting period. The CIS format asks you to disclose all pre-existing diseases or conditions before buying, and warns that non-disclosure may affect claim settlement. Rejections for a pre-existing disease and rejections for non-disclosure deal with each.^[3]

The evidence that decides these questions

• The discharge summary: A history line such as 'known case of' can be read as evidence of an earlier diagnosis. Check whether it gives a date or a source — see the discharge summary.
• Old prescriptions and reports: The dates of diagnosis, advice and treatment are what get compared with the 36 months before your policy began.^[1]
• Your proposal form: What you were asked, and what you answered, is the starting point of any non-disclosure argument: IRDAI's regulations define material information as what the insurer explicitly sought in the proposal form. The insurer must give you a copy with the policy document within 15 days of accepting your proposal.^{[4, 3]}
• A doctor's letter: Your treating doctor can state when the condition was first diagnosed — what such a letter should cover.
