Health insurance in India is more than just a policy—it’s a safety net that ensures you and your family can access quality healthcare without financial stress. Understanding how it works, particularly the pre-existing condition clause, is crucial, as this clause can lead to claim rejections when coverage is needed most. Let’s explore how this clause impacts your policy with real-life examples.
How Does Claim Rejection Work?

This case highlights the common reasons why insurance claims might be rejected and how they happen:
- Non-disclosure of Pre-existing Conditions: If the insured person fails to disclose any pre-existing medical conditions at the time of purchasing the policy, the insurance company might reject the claim if the condition directly contributes to the health issue for which the claim is made.
- Claims During the Waiting Period: Many policies have a waiting period during which certain treatments or conditions are not covered. If a claim is made for treatment within this period, the insurer can deny it.
- Incomplete or Incorrect Documentation: Submitting incomplete or incorrect paperwork can lead to claim rejection. It’s crucial to provide all required documents accurately.
- Treatments Not Covered Under the Policy: If the treatment or condition for which the claim is made is not covered under the policy terms, the insurance company is within its rights to reject the claim.
What Are Pre-Existing Clauses?

How Do They Work?
When you apply for health insurance, insurers usually ask for your medical history. If you have a pre-existing condition like diabetes, hypertension, or a heart condition, the insurer may either:

Imagine Mr. Sharma, who has diabetes, applies for health insurance. His policy might have a waiting period of 2-4 years for diabetes related treatments. This means if he incurs medical expenses due to diabetes within this period, the insurance will not cover it.
However, claim rejections can be avoided by undertaking the following actions:
- Disclosing all medical history accurately when applying for insurance
- Understanding the terms and conditions of your policy, especially exclusions and waiting periods
- Ensuring all documentation is complete and correct when filing a claim
According to Policy Bazaar, out of the total claims rejected, 75% rejections are caused due to limited understanding of health policy and undisclosed pre-existing diseases. This highlights the need to have a better understanding of health policies to avoid claim rejections.
