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 key factors are the **waiting period**, **disclosure requirements**, and **policy features**. ### Rules in India (2026) Under current: - A pre-existing disease is generally a condition diagnosed or treated within the **36 months** before the policy starts. - Insurers **cannot impose a waiting period longer than 36 months (3 years)** for pre-existing diseases on retail health insurance policies. This limit was reduced from the earlier 48 months. - You **must disclose** all existing medical conditions honestly when applying. Non-disclosure can lead to claim rejection. ### What to look for in a policy If you already have a medical condition, prioritize: - Shortest available PED waiting period (many plans offer 2–3 years, and some have paid add-ons to reduce it further). - Coverage for your specific illness after the waiting period. - High claim settlement experience and a wide cashless hospital network. - No restrictive room-rent limits, if possible. - Reasonable co-payment clauses, especially if you're a senior citizen. ### Can you get immediate coverage? For **individual retail policies**, immediate coverage for pre-existing diseases is uncommon. However: - Some insurers offer **waiting-period reduction riders** for an extra premium. - Many **employer group health insurance** policies cover pre-existing diseases from Day 1 or have much shorter waiting periods. ### If you already have insurance If you've maintained continuous coverage and are switching insurers through portability, you may receive continuity benefits for waiting periods already served, subject to policy terms and regulations. If you tell me: 1. your **age**, 2. your **pre-existing disease(s)** (for example, diabetes, BP, thyroid, heart disease), 3. the **sum insured** you want (₹5 lakh, ₹10 lakh, ₹25 lakh, etc.), and 4. your **annual budget**, I can suggest health insurance plans that are well suited for your situation in India in 2026.
