If you have a pre-existing disease (PED) such as diabetes, hypertension, thyroid disease, asthma, heart disease, or kidney disease, you can still buy health insurance in India. The main differences are the waiting period, premium, and underwriting. ### Key rules in India (2026) The biggest recent change is that insurers cannot impose a pre-existing disease waiting period of more than **36 months (3 years)** for retail health insurance policies. Earlier, many plans had a 4-year waiting period. A pre-existing disease generally refers to a condition for which you were diagnosed, treated, or received medical advice before buying the policy. Full disclosure when applying is essential, as non-disclosure can lead to claim rejection. ### What to look for When comparing policies, pay attention to: - **PED waiting period:** Prefer plans with a 1- or 2-year waiting period if available, rather than 3 years. - **Coverage for your specific condition:** Some plans have disease-specific restrictions. - **Co-payment:** Especially common in senior citizen plans. - **Room rent limits:** Unlimited room rent is preferable. - **Restoration benefit:** Reinstates the sum insured after a claim. - **Network hospitals:** Ensure hospitals near you are included. - **Claim settlement service:** Look at insurer reputation and customer support, not just percentages. ### Can you get immediate coverage? Some insurers offer: - Buy-back or reduced waiting period options (for an extra premium). - Zero-waiting-period products for selected conditions, though these typically cost more and come with specific terms and exclusions. ### If you already have a policy If you've completed part of your waiting period and want to switch insurers, portability rules generally allow credit for the waiting period you've already served, provided you port correctly and maintain continuous coverage. ### Best strategy If you have a chronic illness: 1. Buy insurance as early as possible. 2. Disclose every existing medical condition honestly. 3. Choose a high enough sum insured (₹10–25 lakh is common for urban families). 4. Maintain uninterrupted renewals so waiting periods continue to count. If you tell me: - your **age**, - your **pre-existing condition(s)** (for example, diabetes, hypertension, heart disease, etc.), - whether you're looking for **individual, family floater, or senior citizen** coverage, - and your **budget**, I can suggest plans that are well suited for your situation in India in 2026.
