March 31, 2025 By: Naresh Saini0 comments

Health insurance is a crucial financial safeguard against unexpected medical expenses. However, many policyholders face claim rejections due to various reasons, often leading to frustration and financial burden. Understanding why health insurance claims are rejected and how to avoid these pitfalls can save you from unnecessary stress.

In this article, we will explore the common reasons for health insurance claim rejections and proven strategies to ensure your claims are approved hassle-free.

Common Reasons for Health Insurance Claim Rejections

Insurance companies have strict guidelines for claim approvals. Even a minor mistake can lead to rejection. Here are the most common reasons why claims get denied:

1. Pre-Existing Diseases Not Disclosed

• Many insurers reject claims if the policyholder fails to declare pre-existing medical conditions at the time of policy purchase.
• Insurance companies assess risk based on your medical history, and hiding illnesses like diabetes, hypertension, or heart disease can lead to claim denial.

👉 How to Avoid: Always provide complete and accurate health details when purchasing a policy. If you have a pre-existing condition, opt for a plan that covers it after the waiting period.

2. Claim Filed During Waiting Period

• Health insurance policies come with a waiting period for pre-existing diseases and specific treatments like maternity care or joint replacements.
• If a claim is filed before the waiting period ends, it is automatically rejected.

👉 How to Avoid: Read the policy terms carefully and ensure you wait for the completion of the waiting period before making a claim for pre-existing conditions.

3. Incorrect or Incomplete Documentation

• A lack of proper documents is one of the most common reasons for claim rejection.
• Missing hospital bills, doctor’s prescriptions, diagnostic reports, or ID proofs can lead to claim denial.

👉 How to Avoid: Always double-check the required documents before submitting a claim. Keep copies of all medical records and bills to ensure a smooth process.

4. Treatment or Disease Not Covered Under Policy

• Each health insurance plan comes with a list of exclusions—specific illnesses or treatments not covered.
• Cosmetic surgeries, fertility treatments, self-inflicted injuries, and alternative therapies are often not covered in standard policies.

👉 How to Avoid: Before buying a policy, read the exclusions section carefully. If you need specific coverage, choose a plan that includes it.

5. Delay in Filing the Claim

• Every insurance company has a time limit for claim submission.
• If you fail to submit a reimbursement claim within the stipulated time, it may be denied outright.

👉 How to Avoid: Always file your claim as soon as possible after hospitalization. Check the insurer’s deadline for both cashless and reimbursement claims.

6. Policy Lapse Due to Non-Payment of Premiums

• If you miss paying your premium on time, your health insurance policy can lapse.
• Any claims made during this period are rejected as the policy is inactive.

👉 How to Avoid: Set up automatic premium payments or reminders to renew your policy before the due date.

7. Hospital or Treatment Not Listed in the Network

• If you opt for a cashless claim, treatment must be done at an insurer’s network hospital.
• Seeking treatment at non-network hospitals can lead to claim rejection or require reimbursement instead.

👉 How to Avoid: Always check your insurer’s network hospital list before hospitalization to ensure hassle-free claim processing.

8. Fraudulent or Misleading Claims

• If a claim involves false information, fabricated bills, or fraudulent activities, insurers will reject it.
• Some policyholders inflate medical expenses to get higher claim amounts, leading to investigation and rejection.

👉 How to Avoid: Always submit genuine claims with proper documentation to avoid complications.

9. Non-Disclosure of Previous Policies

• If you have multiple health insurance policies and fail to disclose them, the insurer may reject your claim citing non-disclosure.
• Some insurers require coordination between multiple policies for claim processing.

👉 How to Avoid: Always inform your insurer about any existing health insurance policies to ensure smooth claim settlement.

10. Violation of Policy Terms

• Many claims are rejected due to non-adherence to policy rules.
• Common violations include:
  • Admitting to a non-network hospital without informing the insurer.
  • Not following the pre-authorization process for planned surgeries.
  • Exceeding the sum insured limit for a particular treatment.

👉 How to Avoid: Understand and follow your policy’s terms strictly before making a claim.

How to Ensure Your Health Insurance Claim Gets Approved

Now that we have covered the major reasons for claim rejections, let’s look at ways to ensure your claim is processed successfully.

1. Choose the Right Policy

• Select a policy that matches your medical needs and covers pre-existing conditions after the waiting period.
• Check the exclusions, waiting periods, and coverage limits before purchasing.

2. Disclose All Medical Conditions Honestly

• Always provide accurate health details when buying insurance.
• Non-disclosure of medical history can lead to permanent claim rejection.

3. Stay Updated on Policy Terms

• Insurers update policy terms regularly. Keep track of changes to ensure you comply with new rules.
• Read the policy renewal documents every year.

4. Pay Your Premiums on Time

• A lapsed policy means no coverage.
• Set up auto-debit payments or calendar reminders to avoid missing due dates.

5. Get Treatment at Network Hospitals

• Opt for cashless hospitalization in a network hospital for hassle-free claim approval.
• For non-network hospitals, ensure you keep all original medical documents for reimbursement claims.

6. Inform Your Insurer Before Planned Treatment

• If you need planned surgery or hospitalization, notify your insurer in advance.
• Pre-authorization approval is required for cashless treatments.

7. Maintain Proper Documentation

• Keep all medical records, doctor’s prescriptions, test reports, hospital bills, and payment receipts.
• Submit clear and complete documents to avoid unnecessary claim rejection.

8. File Your Claim on Time

• Submit claims within the insurer’s deadline to avoid rejections.
• Keep a digital copy of claim forms and receipts for easy access.

9. Understand Sub-Limits and Co-Payment Rules

• Some policies have sub-limits on room rent, surgeries, and treatments.
• Ensure you know these limits before hospitalization to avoid paying out-of-pocket.

10. Consult Your Insurance Agent or Customer Support

• If you are unsure about claim procedures, speak to your insurance company or agent for clarification.
• Seeking professional guidance can prevent mistakes that lead to rejections.

By following these strategies, you can significantly reduce the chances of claim rejection and ensure a smooth approval process. Having a clear understanding of your health insurance policy and meticulously following claim procedures can make a huge difference in securing the financial support you need during medical emergencies.
