Pre-existing diseases: what counts and what gets excluded
If you've ever been treated for diabetes, hypertension, asthma, thyroid, or even a chronic skin condition, that's a "pre-existing disease" (PED) for any health-insurance application. Most plans cover PEDs only after a waiting period — typically 2 to 4 years.
The PED waiting-period race to the bottom
Until 2022, 4-year waiting periods were standard. Today, several insurers (HDFC ERGO Optima Secure, Star Comprehensive, Niva Bupa Reassure) offer just 2-3 years. A handful of premium plans cover PEDs from day 1 — but they cost 30-50% more.
Disclose. Always.
Non-disclosure is the #1 reason claims get rejected. If your medical records show a treated condition you didn't declare, the insurer can void the policy retroactively — even after they've collected premiums for years. Always disclose; the worst case is a higher premium.
