Health insurance claims being rejected due to pre-existing conditions is one of the most common — and most frustrating — issues policyholders face. When we urgently need financial support for medical treatment, a rejection can feel overwhelming. However, a denial is not the end of the road. With the right steps and support, we can still challenge and overturn an unfair health insurance claim rejection.

Understanding the Rejection
If your insurer has refused your claim on the grounds of a pre-existing disease, here’s exactly what we should do next.
1. Understand Why Your Claim Was Rejected
Insurance companies often reject claims by citing one of the following reasons:
The condition was labelled as pre-existing and not disclosed at the time of purchasing the policy.
The insurer believes the illness existed before the waiting period ended.
Medical records were interpreted incorrectly.
Policy terms were misunderstood.
Before taking action, we should read our claim rejection letter, check our policy wording, and examine our medical history. Many times, claims are rejected due to misinterpretation or incomplete documents.
2. Collect All Medical Records and Evidence
If we believe the rejection is incorrect:
Gather all diagnostic reports, doctor’s notes, prescriptions, and previous medical history.
Make sure we have proof showing that our current health issue is not related to a pre-existing condition or was diagnosed only after our waiting period ended.
Keep all hospital bills and discharge summaries organized.
Accurate and detailed documentation significantly strengthens our case.
3. Re-submit the Claim With Clarifications
Many health insurance claims get approved after a proper resubmission with clear explanations. Include:
An explanation letter.
A doctor’s statement clarifying the onset of illness.
Supporting medical records.
During the second submission, insurers take a fresh look at our file, and many rejections get reversed.
4. File a Formal Complaint With Your Insurance Company
If the insurer continues to deny our claim:
Raise a grievance with the insurer’s internal grievance redressal team.
Maintain written proofs of all email communication.
Ask for a detailed justification of the rejection based on policy documents.
Insurance companies are legally obligated to respond within a specific timeline.
5. Escalate to the Insurance Ombudsman
If the insurer does not resolve our issue satisfactorily, we can approach the Insurance Ombudsman. This route is:
Free of cost.
Faster compared to court cases.
Consumer-friendly.
We’ll need to submit all relevant documents, rejection letters, and communication history.
Challenging a rejected insurance claim alone can be stressful and time-consuming. Incorrect documentation or weak justification can lower our chances of approval. This is where Expert Insurance Claims can help.

Always disclose our complete medical history when buying a health insurance policy.
Choose plans with shorter waiting periods for pre-existing conditions.
Keep copies of all medical documents from check-ups and treatments.
Review policy updates or changes yearly.
