India is witnessing a sharp rise in lifestyle diseases such as cancer, heart disease, and stroke. Long working hours, stress, sedentary habits, and unhealthy diets are increasing the risk of serious medical conditions at younger ages. While regular health insurance covers hospitalization expenses, it may not be enough to handle the overall financial impact of a major diagnosis.
This is where critical illness cover becomes essential. A critical illness policy provides a lump sum payout on diagnosis of specified serious illnesses, helping individuals manage medical and non-medical expenses without exhausting their savings.
What is critical illness cover?
If you are wondering what critical illness cover is, it is a type of insurance that pays a fixed lump sum amount when the insured is diagnosed with a listed serious illness covered under the policy.
Unlike traditional health insurance that reimburses hospital bills, critical illness insurance provides a one-time payout after diagnosis of a covered illness, subject to policy terms.
Lump sum payout concept
- The insurer pays the entire sum insured at once.
- The amount can be used for:
- Advanced treatment
- Post-hospitalization recovery
- Household expenses
- EMIs or loan repayments
- Income replacement during time off work
You are free to use the money as needed, it is not restricted to hospital bills.

Why do you need critical illness insurance?
1. Rising medical costs
Treatment for cancer, heart surgery, or organ transplant can cost ₹10–25 lakhs or more in metro cities.
2. Income replacement
Serious illnesses often require months of recovery, affecting earning capacity. A lump sum helps cover lost income.
3. Covers non-medical expenses
Regular health insurance does not cover:
- Home care
- Travel for treatment
- Special diet
- Household expenses
- Loan EMIs
4. Protects your savings
Without a critical illness insurance policy, individuals may dip into long-term savings or investments.

How it works
- The base term plan provides death benefits.
- A critical illness rider pays a lump sum on diagnosis.
- In some cases, future premiums are waived.
When it makes sense
- Primary breadwinners
- Individuals with dependents
- Those seeking bundled protection
Key limitations to check
- Illness definitions
- Survival period
- Whether rider reduces life cover
- Policy termination rules after claim
What is not covered under critical illness cover?
- Early-stage cancer
- Minor heart conditions
- Pre-existing diseases (during waiting period)
- Illnesses diagnosed within waiting period
- Claims not meeting survival period clause
- Non-specified illnesses
Understanding exclusions is crucial before buying a critical illness cover.
How does a critical illness policy work?
A critical illness policy follows a structured claim process. Unlike regular health insurance that reimburses hospital bills, this policy pays a lump sum amount once specific conditions are met. Here’s a detailed explanation of each step:
- Purchase the policy
You buy a critical illness cover by choosing:
- Sum insured (e.g., ₹10–50 lakhs)
- Policy term
- Standalone policy or rider option
Premium is based on age, medical history, lifestyle habits (like smoking), and coverage amount. Once issued, your coverage begins but is subject to waiting periods.
- Initial waiting period (Usually 90 days)
Most critical illness insurance plans have an initial waiting period of 60–90 days from policy start date.
- If a listed illness is diagnosed during this period, the claim is usually not payable.
- This prevents misuse of the policy by purchasing it after symptoms appear.
After this period ends, coverage becomes active for listed illnesses.
- Diagnosis as per policy definition
Not every diagnosis qualifies automatically.
The illness must:
- Be part of the insurer’s critical illness list
- Meet the exact medical definition mentioned in the policy document
- Be certified by a qualified medical practitioner
- Survival period (Typically 30 days)
After diagnosis, most policies require the insured to survive for a minimum period usually 15 to 30 days.
Why?
- The policy is designed to support long-term treatment and recovery.
- If the insured does not survive the survival period, the claim may not be payable under the critical illness policy (though term insurance may pay separately if combined).
Always check the survival clause carefully before buying.
- Lump sum payout
Once:
- Waiting period is completed
- Illness matches policy definition
- Survival period is met
The insurer pays the entire sum insured in one go.
This payout:
- Is not linked to hospital bills
- Can be used for any purpose
- Is usually tax-free under prevailing tax laws (subject to conditions)
You can use the money for:
- Advanced treatment
- Recovery care
- EMIs and household expenses
- Income replacement during time off work
- Policy termination after payout
In most cases:
- The critical illness cover ends after the lump sum is paid.
- Only one major claim is allowed.
However, some modern plans may offer:
- Multiple claims for unrelated illnesses
- Partial payouts for early-stage conditions
- Continued coverage after first claim (rare and higher premium)
Simple example
Let’s say:
- You buy a ₹25 lakh critical illness insurance policy.
- After 2 years, you are diagnosed with a covered heart attack.
- You survive 30 days post-diagnosis.
The insurer pays ₹25 lakhs as a lump sum even if your hospital bill was only ₹8 lakhs.
The remaining amount can help manage lost income, loan payments, or long-term recovery expenses.
Who should buy a critical illness cover?
- Salaried employees
- Self-employed professionals
- Single-income families
- Individuals with family history of serious illness
- Corporate employees relying only on group health insurance
A group policy may not be portable if you change jobs — having personal critical illness cover ensures continuity.
How much critical illness cover is enough?
Experts suggest:
- At least 3–5 times your annual income
- Factor in existing liabilities (home loan, education loan)
- Consider medical inflation (10–15% annually in India)
For example, if your annual income is ₹12 lakhs, consider a ₹40–60 lakh critical illness cover.
Critical illness cover in India: Cost factors
The premium for a critical illness policy depends on:
- Age
- Smoking and lifestyle habits
- Medical history
- Sum insuredNumber of illnesses covered
- Rider vs standalone policy
Younger individuals typically get lower premiums. Buying early ensures affordability.

For complete protection, consider combining:
- Health insurance
