Best Critical Illness Health Insurance Plans in India
Critical illness insurance (also called serious illness cover) provides a tax-free lump sum payout (100% of sum insured) upon first diagnosis of a covered life-threatening condition like cancer, heart attack, stroke, kidney failure, major organ transplant, paralysis, or coma. The money can be used freely for treatment, income replacement, loans, or recovery — no bills required for reimbursement.

Unlike regular health insurance (which covers hospitalization), critical illness plans focus on major diseases with a lump-sum benefit. They come as:
- Standalone plans (pure critical illness cover).
- Riders/add-ons to health or term insurance (often cheaper, but may have limits).
Why Buy Now?
- Rising cases of lifestyle diseases (cancer, heart issues) in India.
- Medical costs for critical illnesses can exceed ₹20–50 Lakh+.
- Tax benefits under Section 80D (up to ₹25,000/₹50,000 for seniors).
- Waiting period: Usually 90 days (from policy start); survival period: 7–30 days post-diagnosis in most plans.
- Recommended sum insured: ₹10–50 Lakh+ (10–20× annual income for breadwinners).
- Latest trends (2026): Plans cover 20–100+ illnesses; high CSR (95–99%+) from top insurers.
