Critical illness cover

Critical illness cover

Summary

Critical illness cover is a type of insurance that provides a one-time lump sum payout if you are diagnosed with a serious illness listed in the policy, such as cancer, heart attack, or stroke.

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.

Difference between health insurance and critical illness cover

Basis Health Insurance Critical Illness Cover
Claim Type Reimbursement/Cashless Lump sum payout
Trigger Hospitalization Diagnosis of listed illness
Usage Medical bills only Any purpose
Number of Claims Multiple (up to sum insured) Usually one major payout

A critical illness cover in health insurance may be offered as an add-on rider, but it functions differently from standard hospitalization coverage.

How does a critical illness policy work?

  1. Policyholders buy a critical illness policy.
  2. A covered illness is diagnosed.
  3. Survival period (usually 15–30 days) must be completed.
  4. The insurer pays the lump sum.
  5. In most policies, coverage ends after payout.

Critical illness list: diseases commonly covered

The critical illness list varies by insurer, but most policies cover:

  • Cancer of specified severity
  • Heart attack (myocardial infarction)
  • Stroke resulting in permanent symptoms
  • Kidney failure requiring dialysis
  • Major organ transplant
  • Coronary artery bypass surgery
  • Multiple sclerosis
  • Paralysis
  • Aorta surgery

Always review the exact definitions in your critical illness policy document.

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.

Term insurance with critical illness cover

Term insurance with critical illness cover combines life insurance with a critical illness rider.

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:

  1. 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.

  1. 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.

  1. 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
  1. 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.

  1.  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
  1. 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.

Conclusion

A serious medical diagnosis affects not just your health but also your financial stability. While health insurance pays hospital bills, critical illness cover provides financial freedom during one of the most challenging phases of life.

For complete protection, consider combining:

  • Health insurance
  • Critical illness insurance
  • Term insurance with critical illness cover

This layered approach ensures both medical and income protection.
