To ensure timely treatment without draining your savings, this guide walks you through the key aspects of critical illness insurance in India.

What is a Critical Illness Cover in Health Insurance?

A critical illness cover in health insurance is a type of plan which provides financial assistance for critical and life-threatening conditions, such as cancer, heart attack, stroke, kidney failure, and more.

This plan pays a lump sum regardless of the actual cost of treatment. You can also buy a critical illness plan as a separate policy or add it to your existing health insurance for extended coverage.

If you are wondering what some of the important facts are that you should know before buying a critical illness cover, read the pointers below:

How Does Critical Illness Insurance Work?

Critical illness insurance in India works on a benefit basis, where your insurer pays a fixed amount when you are diagnosed with a covered illness. Because the payout doesn't depend on your treatment bills, you may receive it even without hospital admission.

An insured can use this amount for treatment, daily expenses, loan repayments and more.

Here is a detailed view of how a critical illness plan works from your diagnosis to the payout:

Step 1: Diagnosis. A registered medical practitioner diagnoses you with a critical illness or a procedure covered under your policy.

Step 2: Policy-Defined Criteria. Your insurer checks the diagnosis against the definition given in the policy wording. These definitions generally mention severity, required test results, medical evidence, and more.

Step 3: Survival Period. You must survive for a specified number of days from the date of your diagnosis. For instance, most insurers in India specify a 30-day survival period.

Step 4: Lump Sum Payout. Once the review is complete, your insurer credits the sum insured to your bank account as per the policy terms.

You have already noted that this plan pays a lump-sum amount irrespective of treatment costs. These four stages are how your insurer arrives at that payment.

8 Essential Facts About Critical Illness Insurance in India

Here are 8 essential facts about critical illness coverage in India:

Lump Sum Payout

Unlike a traditional health insurance policy, which only pays for hospital bills, critical illness insurance provides a fixed lump-sum payout upon diagnosis. You can use this amount not only for treatment but also for recovery, rehabilitation, or managing household expenses.

Survival Period Requirement

Many insurance companies in India include a survival clause in their critical illness insurance plans, typically around 30 days. This means the insured must survive for a specific number of days after the date to avail the policy benefits.

Waiting Period

The waiting period is typically up to 90 days. During this time, the insured person cannot make any claims. Any diagnosis made during this period will not be covered under the policy.

Specific Coverage Range

Critical illness insurance plans only cover a specific range of diseases. Diseases such as cancer, cardiovascular diseases, heart attack, stroke and kidney failure. The exact list may vary by insurer, so review the policy wording before you buy.

Single Claim Policy

In critical illness insurance, your insurer allows only one claim. After your first claim, your insurer will pay the entire sum insured. This means that once the benefit is paid, the policy will cease to exist.

Stand-alone or Rider

You can buy it as a standalone policy or add it to your existing health insurance policy as a rider. Your choice depends on your coverage needs and budget.

Tax Benefits

Premiums paid for health insurance plans are eligible for tax deductions under Section 126 of the Income Tax Act, 2025. This section allows a deduction of ₹25,000 per financial year for individuals aged 60 or less and ₹50,000 for senior citizens.

No Coverage for Pre-Existing Diseases(PED)

Many insurance companies in India do not cover pre-existing diseases immediately. However, some insurers may offer coverage after a specified waiting period, depending on policy terms and underwriting conditions.

Who Should Consider Critical Illness Insurance?

Buying critical illness insurance in India is important for anyone whose income may stop during a long treatment. This becomes even more necessary when your savings are already committed to loans, education expenses, family responsibilities and more. Here is a detailed view of the buyers who need it the most:

1. Primary Earners: This is suitable for individuals whose salary runs the household. As a long recovery stops that income, your EMIs, school fees and daily expenses continue as usual. Here, a lump sum payout helps you manage them while you are away from work.
2. People With a Family Medical History: As cancer, heart disease, stroke and kidney disease run in families, your long-term risk increases. Buying a critical illness cover early, while you are healthy, is generally easier. Insurers may add restrictions once a diagnosis is on record.
3. Self-Employed Professionals and Business Owners: Such buyers do not get employer cover, paid sick leave, salary continuity and more. An insured can use the payout for treatment, a stand-in manager, the running costs of the business, etc.
4. Younger Buyers: Insurers generally set lower premiums in your late twenties and thirties. Buying a critical illness plan early also helps you complete the waiting period before health complications increase at a higher age.
5. People With Large Loans: Your home loan or business loan continues through the treatment period. Here, a critical illness payout helps you service that loan without using your emergency savings.

Critical Illness Insurance vs Health Insurance: Why You May Need Both

Whether you are diagnosed with cancer or heart disease, treating critical illness in India is extremely costly. According to the New Indian Express, in India, approximately 43% of households face financial distress due to the rise in cancer treatment costs.

The treatment not only costs an overnight hospital stay but also procedures such as chemotherapy and radiotherapy. In some situations, you might need to leave your job during treatment, which can lead to a loss of income.

To understand this better, let’s learn this with an example:

Scenario:

Rohan, a 35-year-old software engineer, has been diagnosed with stage 2 cancer.

What would happen without a critical illness insurance plan? Let’s understand the situation given below:

1. With a Standard Health Insurance Plan: His standard health insurance covers ₹5 lakh for hospitalisation and surgery. However, chemotherapy costs ₹3 lakh and may only be partially covered. Additionally, he takes six months off work, resulting in a loss of ₹6 lakh in income. This creates a significant financial burden, even with basic health insurance.
2. With a Critical Illness Insurance Plan: As soon as his cancer diagnosis is confirmed, he gets a lump sum payout of ₹10 lakh (if he chooses the cover) from his insurer. He further uses this amount of money to pay for the expensive medical treatments. Settles his monthly EMIs and manages his day-to-day expenses without touching his savings.

This clearly highlights why relying solely on traditional health insurance may not be sufficient to cover critical illnesses.

To stay adequately protected, it is important to renew health insurance policies on time and consider adding a critical illness cover from Bajaj General Insurance for enhanced financial security.

Common Exclusions Under Critical Illness Insurance

Insurers clearly declare the conditions and situations they will not pay for under a critical illness plan. These exclusions vary by insurer and policy. So, you must review the policy wording carefully before finalising your purchase.

Here are the exclusions most critical illness policies in India carry:

1. Pre-Existing Diseases: Most insurers impose a waiting period on the conditions you already had when the policy started. While the initial waiting period may be shorter, the waiting period for pre-existing diseases is generally 36 months, as per IRDAI.
2. Diagnosis During the Initial Waiting Period: Insurers do not pay for an illness first diagnosed within the initial waiting period. This applies even if that illness appears on your policy's covered list, as per the policy terms.
3. Conditions Below the Policy Definition: Insurers generally do not pay for early-stage or less severe forms of a listed illness. Under IRDAI guidelines on standardisation, such policy wordings define each illness by exact severity, test results, the procedure, and more. Hence, a diagnosis alone may not settle your claim.
4. Congenital Conditions and Birth Defects: Insurers generally do not cover conditions present from birth under a critical illness plan. Illnesses arising directly from such conditions are also not payable. However, check your policy wording, as these criteria vary between providers.
5. Self-Inflicted Injuries and Substance Misuse: These generally include claim expenses for self-inflicted injuries, medical costs arising from substance abuse and more. Insurers also do not pay for health concerns arising from the misuse of alcohol, drugs and other intoxicating substances.
6. Sexually Transmitted Diseases and HIV or AIDS: Most insurers in India declare these conditions as standard exclusions in their critical illness policy wordings. Such exclusions generally apply regardless of treatment cost, the hospital you choose, the duration of the illness, and more.
7. War, Civil Unrest and Nuclear Contamination: Insurers do not cover an illness or an injury caused by war, war-like situations, civil unrest and more. Claims arising from nuclear or radioactive contamination are also not payable, as per the policy terms.

Aside from the exclusions, you must also know about one protection you get with a critical illness plan. This is called the moratorium period, and under IRDAI, it applies after 60 months of continuous cover.

Once this period is over, insurers cannot contest your claim on the grounds of non-disclosure or misrepresentation. However, established fraud remains an exception to it.

Things to Consider Before Buying Critical Illness Insurance

Now that you understand who needs critical illness cover and what it excludes, consider these crucial factors before buying. Here is a detailed view of such factors that you must take a look at to make an informed decision:

1. Definition of Each Illness: While buying a critical illness plan, you must understand how each covered illness is defined. A plan may list 40 or more illnesses and still pay only at a specified severity, as per the policy terms.
2. Coverage Amount: For quality care and savings, opt for a coverage which is practical for critical illness treatment in India. Choose a coverage which accounts for the treatment cost, the income you may lose during recovery and more.
3. Waiting Period and Survival Period: Most insurers impose a waiting period after which the actual coverage begins. You must also check the survival period, which is the number of days you must survive after your diagnosis. These generally vary between insurers.
4. Renewability and Entry Age: A critical illness plan with longer renewability keeps you covered for years. Insurers also allow flexibility in entry age. As per the IRDAI, they can no longer refuse a health insurance product only on the basis of a maximum entry age of 65 years. However, underwriting conditions still apply.
5. Free-Look Period: As per the IRDAI, you get a free-look period of 30 days from the date you receive your policy document. Within this period, you may review the terms and return the policy if it does not suit your healthcare needs.
6. Standalone Policy or Rider: A rider generally costs less than a standalone policy. However, its sum insured is often tied to your base policy, and the cover ends when that policy ends. Hence, compare both options before finalising your purchase.

How to File a Critical Illness Insurance Claim?

As you buy critical illness insurance in India, you must know how to claim it during a health emergency. You get the claim amount as a lump sum once your diagnosis is confirmed and the policy conditions are met. For this, take note of the steps below:

Step 1: Intimate the Claim. Get in touch with your insurer through their customer touchpoints or inform them about the claim using their mobile application. Insurers generally specify a notification window in the policy wording, and you must intimate the claim within that period.

Step 2: Fill the Claim Form. Obtain a claim form from your insurer, fill it out carefully and attach the necessary documents. Also attach the bank mandate your insurer uses to credit the payout.

Step 3: Submit the Medical Evidence. Ensure you collect documents such as the diagnostic reports, the specialist certification and other relevant documents. Submit these to your insurer as requested.

Step 4: Claim Verification. Your insurer will review your claim and the provided documents against the policy definition. They may also ask for further medical records, an independent medical opinion, etc.

Step 5: Claim Settlement. Once the review is complete and the survival period is over, you will get the sum insured as per the policy terms.

As per IRDAI, insurers must settle non-cashless claims within 15 days of claim submission. If they delay it beyond this period, you are entitled to interest at the bank rate plus 2%.

Documents Required for a Critical Illness Insurance Claim

Insurers generally ask for a common set of documents when you make a critical illness claim. These documents establish your diagnosis, its severity, the date on which it was confirmed and more. For this, take note of the list below:

1. Filled and Signed Claim Form: This records your claim details and your consent to release the medical information to your insurer.
2. Bank Mandate or NEFT Form: Submit it along with a cancelled cheque, as it helps your insurer credit the lump sum to your account.
3. Doctor's Certificate Confirming the Diagnosis: This establishes the condition, the date of diagnosis, its severity and more.
4. Diagnostic and Investigation Reports: These generally include the laboratory reports, the imaging reports, the histopathology evidence, etc.
5. Specialist's Certificate or First Consultation Letter: This confirms that a qualified practitioner in the relevant speciality made the diagnosis.
6. Discharge Summary: You must produce it if your treatment involves a hospital stay, as it supports the medical history behind your diagnosis.
7. Policy Copy and Photo Identity Proof: These confirm your cover and your identity as the insured person.

However, insurers may ask for additional details that you must prepare while making a claim. So, confirm the exact list with your insurer when you intimate your claim. You must also keep the original documents safe, as insurers may ask to see them even if they accept copies at submission.
