What Is A Pre-Existing Condition in Health Insurance?

A pre-existing condition is an ailment before you begin your health insurance policy. This includes all forms of diseases like asthma, diabetes, heart disease, hypertension, arthritis, all forms of diseases, and even mental disorders. Pre-existing conditions put the clients at high risk since such conditions may need constant medical attention or monitoring.

Health insurance often comes with conditions and limitations that cater to pre-illness insurance, as claims are highly expected. From a policyholder’s perspective, insurers may put an assortment of conditions in place during the underwriting process, such as having waiting periods, charging more premiums, or not covering specific treatments due to a particular medical condition.

What Is Pre-Existing Disease Cover?

Generally, pre-existing disease:

  • Limited to practicing for a specified time before you can start claiming for treatments associated with the pre-existing condition.
  • Specific exclusions, where the insurer may not cover treatment for certain pre-existing conditions.
  • Possible premium increases to reflect the added risk of covering someone with a pre-existing disease.

It’s essential to review the specific terms of pre-existing disease coverage when purchasing health insurance to understand what’s included and any conditions attached.

The Importance of Disclosing Pre-Existing Conditions

Being transparent about your health is crucial when purchasing a health insurance policy. Here's why you must disclose all pre-existing conditions upfront:

How Does Pre-existing Disease Impact Your Health Insurance Coverage?

Insurance is a concept where the insurance company offers financial assistance in case something unfortunate happens to the insured asset per the terms and conditions. In this case, the probability of claims rises since the insurance companies know that a person already has a pre-existing condition  Therefore, health insurance companies are  reluctant to cover  pre-existing diseases. Some might cover them per terms and conditions and charge a higher premium.

Why Do Health Insurance Policies Treat Pre-Existing Conditions Differently?

Insurance companies view people with pre-existing conditions as higher-risk clients because of the potential for increased medical costs. Individuals with chronic or ongoing health issues may need frequent medical attention, making them more likely to file claims. To manage this risk, insurers may:

Increase premiums

Higher premiums are often charged to individuals with pre-existing conditions to offset the expected medical costs.

Impose waiting periods

Insurers may require you to wait for a specific period—often between 12 and 36 months—before the policy covers your pre-existing conditions.

Exclude certain conditions

In some cases, specific pre-existing diseases may be excluded from coverage entirely, meaning you won’t be able to claim for those conditions even after the waiting period ends.

Types of Waiting Periods for Pre-Existing Diseases

There are a few types of waiting periods to consider when purchasing health insurance for pre-existing conditions:

Initial Waiting Period

The initial waiting period for the insurer ranges between 12 and 36 months, within which you cannot claim for any previous illness.

Maternity Waiting Period

Any policy offering maternity benefits may be followed by a waiting period for pregnancy expenses even if you have already been diagnosed with the mentioned diseases.

Condition-Specific Waiting Period

It’s necessary to mention that some insurers might have different waiting periods for particular pre-existing conditions. For instance, one policy might have a shorter waiting period for conditions such as asthma but longer for diseases such as heart complications or diabetes.

Knowledge of these waiting periods and how they choose your state of health insurance will enable you to make the right choice.

Effects of a Pre-existing Disease on Your Health Insurance

Here’s a list of repercussions a pre-existing disease might have on your health insurance policy. Different insurance companies might have different clauses. Thus, it is suggested that the respective policy wording be carefully reviewed before buying a health insurance plan.

Premium Loading

This means the premium charged will be on the higher side. The premium will be loaded because the insurance company is taking the risk of covering a pre-existing disease. Such premium loading is only applicable at the time of purchasing the policy. It cannot be charged again if the policy is renewed continuously without any break in between.

Waiting Period

This is the period for which you have to wait before the pre-existing illness is covered by the insurance policy. There is no standard waiting period. It depends upon the illness, the cover, and the insurance company offering the policy. For example, if a hernia is declared as pre-existing disease, the waiting period for it will be around four years. This means the policy will cover hernia after four years from policy purchase date considering there is continuous coverage.

Premium Loading + Waiting Period

There might be situations where you will be charged a higher premium as well as have a long waiting period to cover an illness. Such a situation arises because of a severe condition like high hypertension.

Medical Check-up

If you have a pre-existing disease, the insurance company might ask you for a medical check-up. The insurance premium will be based on the test results. There is a chance that the insurance company might refuse to offer a policy if the results are unfavourable.
 

Permanent Exclusion

The insurance company may offer coverage but exclude pre-existing conditions. In this case, you would need to agree that the pre-existing condition will be permanently excluded from the policy. This means you won’t be covered for that specific condition, but you will still be protected for other health issues, subject to the terms and conditions of the policy.
 

Policy Denial

The insurance company can refuse insurance coverage based on pre-existing conditions. In such cases, they will deny your health insurance policy application.

Understanding Waiting Periods for Pre-Existing Diseases

When you purchase a health insurance policy, coverage for pre-existing conditions doesn't start immediately. You have to serve defined waiting periods first before expenses related to pre-existing illnesses are covered. Here is what you should know:

  • Initial Waiting Period: The first 30-90 days after policy purchase when no claims are payable, including for pre-existing diseases. Applies to all policyholders.
  • Pre-Existing Disease Waiting Period: The exclusive waiting period applied specifically to pre-existing conditions, which is typically 2-3 years.
  • Disease-specific Waiting Periods: Some policies may have additional waiting periods for certain illnesses like cardiac ailments, kidney disease, etc.
  • Factor Impacting Waiting Periods: Age, location, type of policy and insurer rules can impact pre-existing disease waiting periods.
  • Reduced Waiting Periods: Some insurers now offer 1-2 year waiting periods instead of 3 for faster coverage.
  • Portability: You can port your policy to retain accrued waiting periods when switching insurers.
  • Premiums: Higher premiums are usually charged for immediate coverage or lower waiting periods.

Carefully go through the fine print to understand applicable waiting periods. Opt for insurers offering reduced waiting times for faster coverage of pre-existing conditions. Disclose full medical history upfront to avoid claim disputes later.
