Health insurance safeguards you against rising medical expenses, but if you already have a pre-existing disease (PED), your coverage may come with specific conditions. A pre-existing disease refers to any illness or medical condition that was diagnosed or treated before you bought the policy. In such cases, insurers often apply waiting periods or certain exclusions, which can affect your claim eligibility. Let’s understand how PED coverage works in health insurance in detail.

Pre Existing Disease Health Insurance : Overview

The Insurance Regulatory and Development Authority of India (IRDAI) defines pre-existing diseases (PED) as injuries, sickness, or any medical conditions that are diagnosed before buying a health insurance policy. Severe cases of injury are also considered as PED in some policies. This excludes if a policyholder is diagnosed with an illness within the first three months of purchasing a policy.

What is pre-existing disease in health insurance?

A pre-existing disease or PED is an illness or medical condition that the policyholder has before purchasing a health insurance policy. As per the Insurance Regulatory and Development Authority of India (IRDAI), if the insured was diagnosed with a disease or medical condition up to 48 months before buying the policy, it is termed as a pre-existing illness.

Some of the common examples of PED include all the long-term health issues such as high blood pressure, diabetes, thyroid, asthma, etc.

The healthcare costs of a pre-existing disease are typically higher, which is why some health insurers have exclusions or higher premiums for pre-existing conditions. Therefore, it is important to disclose all pre-existing conditions when purchasing health insurance to avoid any future claim rejections or complications.

What is the waiting period for pre-existing diseases in health insurance?

After purchasing a health insurance policy, people cannot file claims immediately. For this, they have to wait for a certain period during which they cannot claim benefits. The initial waiting period is the first 30 days after purchasing the insurance. It is usually common across all health plans. However, this may vary from policy to policy.

Insurers can get reimbursements for the treatment of their pre-existing conditions after the completion of the waiting period. Typically, this duration can be anywhere between 30 days to 2 years. However, this may vary among different providers and depends on the applicant’s age, policy, type of illness and other such factors.

Why do health insurance companies restrict coverage for pre-existing conditions?

Health insurance companies often limit immediate coverage for health insurance pre existing conditions to manage risk and keep premiums affordable for all policyholders. Covering pre-existing illnesses from day one could lead to a surge in claims, potentially destabilizing the insurer's finances and driving up premium costs for everyone, including those without such conditions. This risk management strategy ensures the sustainability of the insurance pool.

Why is it important to disclose pre-existing diseases to your insurer?

Transparency is key when purchasing health insurance. Failing to disclose health insurance pre existing conditions can lead to serious repercussions later. If the insurer discovers an undisclosed pre-existing condition during a claim, they have the right to reject the claim and even cancel your policy. Honest disclosure ensures that your policy remains valid, even with a waiting period for PED coverage, ultimately providing the financial security you sought and preventing claim denials when you need them most.

List of pre-existing diseases covered in health insurance in India

Pre-existing diseases are health conditions that individuals have prior to purchasing a health insurance policy.

Here is a list of pre existing disease in health insurance that are commonly considered

  • High blood pressure
  • Asthma
  • Thyroid
  • Diabetes
  • COPD

  • idney disease

How do pre-existing diseases affect health insurance policies?

Pre-existing diseases wield significant influence over your health insurance journey, impacting both what's covered and how much it costs. Insurers meticulously assess the risk associated with these prior health conditions, often resulting in increased premiums to offset potential claims. You might also encounter extended waiting periods before coverage kicks in for treatments related to your pre-existing illness, or even specific exclusions where certain treatments won't be covered at all.

Furthermore, individuals applying for health insurance with pre-existing conditions may face more stringent underwriting processes. This could mean limitations on the overall benefits you're eligible for. In some cases, particularly with severe pre-existing conditions, certain insurers might unfortunately decline coverage altogether. Therefore, a thorough understanding of how pre-existing diseases in health insurance shape policy terms is absolutely vital for anyone seeking comprehensive protection without unexpected limitations or exorbitant costs. Knowing these implications empowers you to compare policies effectively and find one that best suits your health needs and budget.

Important things to know about health insurance for pre-existing medical conditions

Here are a few things that you must be aware of about buying a health insurance policy that covers pre-existing diseases:

● Disclose any pre-existing medical condition

It is mandatory to disclose any pre-existing diseases that you may have at the time of buying a health insurance policy. In case of non-disclosure, the insurance company can rightfully reject your claim. Providing false or misleading information or hiding health details from the insurer will complicate matters at the time of raising claim requests. Eventually, burdening you financially at the time of a medical emergency.

● Insurance terms and conditions may differ for pre-existing illnesses

Most insurance companies ask for medical check-ups to screen pre-existing health issues before offering a health insurance policy. Some insurers may also consider the applicant’s age and medical history before providing pre-existing disease coverage. The screening process, the list of pre-existing conditions, and the waiting period will differ for different insurance companies and health plans. Therefore, it is advisable to check the terms and conditions before opting for a health insurance policy.

● Pre-existing illness can affect insurance premiums 

It is important to keep in mind that insurers charge higher premiums to people with pre-existing illnesses. The insurance company will determine the exact premium amount based on an applicant's age, illness, etc. However, applicants must be transparent about disease history regardless of the premium charges.

● Not all health plans cover pre-existing diseases

There may be health plans that do not cover applicants against pre-existing ailments. Also, in many cases, insurers may not cover some pre-existing diseases in health insurance for the entire policy tenure. Therefore, you must check with the insurance company about this and select a policy accordingly.

Pro Tip

How to reduce the waiting period for pre-existing conditions in health insurance?

If you are worried about the long waiting time for PED in health insurance, there are a few smart ways to reduce it. Choose a health plan that offers a shorter waiting period or look for insurers that allow you to buy a rider to cut down the time. Maintaining continuous coverage without breaks also helps. Some disease-specific plans may even provide faster coverage for certain conditions. Always compare policies before buying to ensure you get the best benefits.

How waiting periods work for pre-existing disease coverage

Waiting periods are a standard feature in insurance for pre existing medical conditions. Here's how they typically function:

  • Specific duration: A defined period (e.g., 2 to 4 years) must pass from the policy's commencement date before coverage begins for declared pre-existing illnesses.

  • Condition-specific: The waiting period usually applies specifically to the pre-existing conditions disclosed at the time of policy purchase.

  • Gradual coverage: Some policies might have a phased approach, where coverage for PEDs increases gradually over the waiting period.

  • No coverage during period: Generally, no claims related to the pre-existing condition are admissible during the waiting period.

Frequently asked questions

What is PED in health insurance?

PED stands for pre-existing disease. It refers to any medical condition that the policyholder has been diagnosed with before purchasing the health insurance policy.

How are pre-existing conditions determined?

Health insurance companies usually look into the medical history of the policyholder, such as past and current illnesses, hospitalisations, surgeries, medication usage, etc. The insurance company may also request medical reports or physical examinations to determine the pre-existing conditions.

What are some examples of pre-existing health conditions?

Some examples of pre-existing conditions are diabetes, hypertension, cancer, asthma, chronic obstructive pulmonary disease (COPD), heart disease, etc.

Does insurance cover pre-existing diseases?

Yes, most health insurance policies in India offer coverage for pre-existing diseases, but this coverage typically kicks in after a specified waiting period, which can range from one to four years depending on the insurer and the policy terms. While a waiting period is common, some policies may offer options to reduce this duration, and a few specialized plans might even provide immediate coverage for pre-existing conditions, often at a higher premium. Therefore, it's crucial to carefully review the policy details to understand the waiting period applicable to pre-existing illnesses.

How long is a condition considered pre-existing?

According to the Insurance Regulatory and Development Authority of India (IRDAI), a pre-existing disease is defined as any condition, 1 ailment, injury, or disease that was diagnosed or for which medical advice or treatment was received from a physician within the 36 months preceding the commencement date of the first policy issued by the insurer. While this 36-month window is a regulatory guideline, some insurance providers might also consider conditions existing beyond this period as pre-existing, so it's important to understand the specific definition used by your insurer.

What is the IRDA rule for pre-existing disease?

The IRDAI has established regulations to safeguard policyholders' interests regarding pre-existing diseases, stipulating that the maximum waiting period for these conditions is three years of continuous coverage. Importantly, insurers are prohibited from denying claims for any pre-existing condition after this mandatory waiting period has been served, provided there was no misrepresentation during the policy application. Full and honest disclosure of all pre-existing conditions during the application process remains a crucial obligation for policyholders to ensure claim admissibility.

Which diseases are not covered in health insurance?

While the specifics can vary between policies, there are common exclusions in health insurance in India, including cosmetic surgeries, infertility treatments, routine pregnancy care (unless specifically covered), most dental treatments, illnesses arising from substance abuse, self-inflicted injuries, sexually transmitted diseases, congenital external conditions, and often treatments for obesity and alternative therapies unless explicitly included. Additionally, some pre-existing conditions might be permanently excluded in certain policies, even after the waiting period, highlighting the importance of carefully reviewing the policy's list of exclusions.

What if I don't mention pre-existing disease in health insurance?

If you hide a pre-existing condition while buying health insurance, your insurer can reject future claims related to that illness. In some cases, your policy itself may be cancelled due to non-disclosure. Always declare your medical history honestly.

What is the 3-year rule for health insurance?

The 3-year rule refers to the waiting period for certain pre-existing diseases. Many health plans cover PEDs only after you’ve continuously held the policy for 2–4 years. Some insurers specifically follow a 3-year waiting period before PED coverage starts.

Can pre-existing diseases be covered from day 1 in health insurance?

Generally, no. Most insurers impose a waiting period of 2–4 years for PED coverage. However, a few specialised or premium plans may offer day-1 coverage for pre-existing conditions, usually at a higher premium.
