Pre-existing Disease Coverage

A pre-existing disease (PED) is any health condition diagnosed or treated before you bought the policy — diabetes, hypertension, asthma, thyroid disorders, heart conditions, or cancer history. Insurers treat PEDs differently because they directly affect future risk.

How insurers treat PEDs

• Apply a PED waiting period of 2–4 years before the condition becomes claimable.
• Charge a premium loading reflecting the higher risk.
• Sometimes exclude a specific condition permanently — read the policy schedule carefully.

The non-disclosure trap

If you hide a PED at proposal stage, the insurer can reject a claim years later — even after multiple successful renewals — because the proposal was misrepresented. Always disclose. A higher premium is better than a denied claim.

How to reduce the impact

• Buy younger — PED waiting periods are easiest to outlast.
• Look for plans with the shortest PED wait (some are 1 year for an extra premium).
• If you have a serious condition, check disease-specific plans (diabetes-friendly, cancer cover) — they often offer faster coverage.
• Use portability to switch insurers without losing waiting-period credit already accrued.
