What Is Critical Illness Insurance?
Critical illness (CI) insurance is a benefit-based policy that pays a pre-agreed lump sum upon first diagnosis of a covered serious illness — regardless of actual treatment costs. This distinguishes it from regular health insurance, which reimburses hospitalisation expenses. The lump sum can be used for treatment, income replacement, home modifications, debt repayment, or any financial need arising from the diagnosis.
Why Critical Illness Cover Matters
Treating serious illnesses is extremely expensive. Consider:
- Cancer treatment: ₹5–30 lakh depending on type and stage
- Heart bypass surgery: ₹3–7 lakh
- Kidney transplant: ₹10–15 lakh
- Stroke rehabilitation: ₹2–10 lakh
A standard health insurance plan of ₹5 lakh may be exhausted quickly. A critical illness plan provides additional funds to bridge this gap and cover non-medical costs like lost income during recovery.
Which Diseases Are Covered?
Standard critical illness policies cover 20–36 conditions. Common inclusions:
Cardiac Conditions
- Myocardial infarction (first heart attack of specified severity)
- Open heart replacement or repair of heart valves
- Primary pulmonary arterial hypertension
- Heart failure of specified severity
Cancer
- Cancer of specified severity (major cancers)
- Note: Early-stage cancers (CIS, borderline malignancies) are typically excluded
Neurological Conditions
- Stroke resulting in permanent symptoms
- Multiple sclerosis with persisting symptoms
- Major head trauma
- Parkinson's disease (before age 50 in some plans)
Organ Failure
- Kidney failure requiring regular dialysis
- Liver failure of advanced stage
- Lung failure of specified severity
Other Critical Conditions
- Major organ transplant
- Benign brain tumour
- Blindness (permanent and irreversible)
- Deafness (permanent and irreversible)
- Total loss of limbs
- Aplastic anaemia
- Motor neuron disease
- Coma of specified severity
How Claims Work
- Diagnosis: You are diagnosed with a covered illness
- Survival period: Most plans require a survival period of 30 days post-diagnosis before paying the claim
- Documentation: Submit diagnosis reports, doctor certificates and claim form
- Payout: Insurer pays 100% of sum insured as lump sum
- Policy status: In most plans, the policy terminates after CI claim. Some plans continue with reduced sum insured.
Key Policy Features to Compare
- Number of covered conditions: More is better — look for 36+ conditions
- Waiting period: Typically 90 days initial waiting period plus 30-day survival period
- PED waiting period: 2–4 years for pre-existing conditions
- Sum insured: Should cover treatment cost plus 2–3 years of income replacement
- Recurrence: Some plans cover a second occurrence of a different condition
CI Cover vs Health Insurance: Which First?
These products serve different purposes. Health insurance pays your hospital bills; CI insurance pays you directly so you can manage your life. The ideal portfolio includes both. If budget is constrained, prioritise a comprehensive health policy first, then add CI cover.
Best Sum Insured for CI Coverage
Recommended sum insured: ₹25 lakh to ₹1 crore, depending on income and family situation. A ₹50 lakh CI plan for a 35-year-old costs approximately ₹6,000–₹10,000 per year — making it highly affordable protection for life-altering events.
