A health insurance claim rejection can be stressful, especially when you are already dealing with hospital bills and medical treatment. However, a rejected claim does not always mean that you have no further option.

The first step is to understand why the claim was rejected. The insurer should communicate the applicable reason and policy basis. After reviewing the rejection, you can submit additional documents, request reconsideration, raise a formal grievance with the insurer and, where applicable, escalate the matter through IRDAI’s Bima Bharosa grievance mechanism.

Here is what you should know if your health insurance claim has been rejected.

What Does Health Insurance Claim Rejection Mean?

A claim is rejected or repudiated when the insurer determines that the claim is not payable under the applicable policy terms and conditions.

A claim may be rejected because:

• The treatment is excluded under the policy
• The applicable waiting period has not been completed
• The condition is treated as a pre-existing disease under the policy
• Required information or documents were not provided
• The policy was not active when treatment took place
• The treatment does not meet the policy’s coverage conditions
• There was non-disclosure or misrepresentation of relevant information
• The claim does not satisfy a policy condition

The exact reason is more important than simply seeing a status such as “claim rejected.”

Common Reasons for Health Insurance Claim Rejection

1. Treatment Falls Under a Policy Exclusion

Every health insurance policy has exclusions.

For example, certain treatments, procedures, expenses or conditions may be excluded from coverage.

If the treatment falls under a clearly applicable exclusion, the insurer may reject that portion of the claim.

Before disputing the rejection, compare the reason given by the insurer with the policy wording and Customer Information Sheet (CIS).

2. Waiting Period Has Not Been Completed

Health insurance policies can have waiting periods for:

• Initial illnesses
• Specific diseases or procedures
• Pre-existing diseases
• Maternity-related benefits, where applicable

For example, if a policy has a 24-month waiting period for a particular condition and treatment takes place during that period, the claim may not be payable.

The applicable waiting period should be checked in the policy documents.

3. Pre-Existing Disease

A claim may be questioned or rejected if the insurer determines that the treatment relates to a pre-existing disease and the applicable waiting period has not been completed.

This is why accurate disclosure during the proposal stage is important.

If you believe the insurer has incorrectly classified a condition as pre-existing, ask the insurer to provide the specific medical evidence and policy clause on which the decision is based.

4. Non-Disclosure or Incorrect Information

Providing incomplete or incorrect information when buying insurance can create problems during claim assessment.

For example, problems can arise if relevant medical history, previous treatment or other information specifically asked for in the proposal form was not disclosed.

If the insurer cites non-disclosure, request a copy or reference to the relevant information and the policy provision relied upon.

5. Documents Are Missing

A claim may remain pending or face difficulty if important documents have not been submitted.

Common documents can include:

• Claim form
• Discharge summary
• Final hospital bill
• Detailed bill
• Prescriptions
• Investigation reports
• Doctor’s advice
• Pharmacy bills
• Payment receipts
• Bank details
• Previous medical records, where relevant

The exact documents depend on the claim.

If the insurer says documents are missing, ask for a specific list of outstanding documents rather than submitting unrelated paperwork.

6. Treatment Is Not Medically Necessary Under the Policy

Some policies contain conditions relating to medical necessity and admissibility of treatment expenses.

For example, certain expenses may not be payable if they do not meet the policy’s requirements.

If this is the reason for rejection, ask the insurer to explain how the treatment or expense fails to meet the relevant policy condition.

7. Policy Was Not Active

A claim can face rejection if the policy was not in force on the relevant date.

Possible issues include:

• Policy expiry
• Non-payment of premium
• Policy cancellation
• Coverage not yet commenced
• Other policy-status issues

Check the policy schedule and premium/payment records to verify the coverage period.

8. Claim Does Not Meet Policy Conditions

Apart from exclusions and waiting periods, a policy can contain other conditions affecting claim admissibility.

For example, there may be:

• Deductibles
• Co-payment
• Sub-limits
• Room-rent limits
• Disease-specific limits
• Network hospital conditions
• Pre-authorisation requirements

A rejection letter should be examined alongside the relevant policy clause rather than relying only on a verbal explanation.

What to Do If Your Health Insurance Claim Is Rejected

Do not immediately assume that the decision is final. Follow a systematic process.

Step 1: Get the Rejection Reason in Writing

If you were only told over the phone that your claim was rejected, ask for the decision and reasons in writing.

Keep:

• Claim number
• Policy number
• Rejection letter/email
• Date of rejection
• Hospital records
• All correspondence with the insurer or TPA

A written reason makes it easier to determine whether the decision is consistent with the policy.

Step 2: Read the Relevant Policy Clause

Find the exact clause mentioned in the rejection.

For example, if the insurer says:

“Claim rejected due to waiting period”

check the waiting-period section.

If it says:

“Pre-existing disease”

check the definition of PED and the applicable waiting period.

If it says:

“Exclusion”

check the exclusions section.

This helps you distinguish between a genuine policy exclusion and a possible misunderstanding.

Step 3: Ask for the Basis of the Decision

If you disagree with the rejection, write to the insurer and ask:

• Which specific policy clause was applied?
• What medical record supports the decision?
• What document or information was considered?
• Why does the treatment fall under the cited exclusion?
• What additional documents can be submitted for reconsideration?

Keep the communication factual and attach supporting documents.

Step 4: Submit Additional Documents if Required

If the rejection resulted from missing information, submit the required documents as soon as possible.

Depending on the situation, these could include:

• Doctor’s certificate
• Medical history
• Diagnostic reports
• Previous prescriptions
• Hospital records
• Discharge summary
• Investigation reports
• Bills and receipts

Ask the insurer to confirm receipt.

Step 5: Request Reconsideration

If you believe the claim was incorrectly rejected, submit a formal request for claim reconsideration/review.

Clearly explain why you disagree.

For example:

The rejection states that the treatment relates to a pre-existing disease. However, the attached medical records show that the diagnosis was made after the policy commencement date. Kindly review the claim in light of the enclosed documents and the applicable policy terms.

Avoid making unsupported statements. Refer to actual documents and policy clauses.

What If the Insurer Still Rejects the Claim?

If the issue is not resolved through normal claim communication, you can use the insurer’s Grievance Redressal Officer (GRO).

IRDAI’s Bima Bharosa FAQ says policyholders should first approach the insurer’s Grievance Redressal Officer with the complaint and supporting documents. The insurer should resolve the grievance within 15 days of receiving it.

What to Include in the Grievance

Your complaint should contain:

• Policy number
• Claim number
• Date of treatment
• Hospital name
• Amount claimed
• Rejection reason
• Why you disagree
• Relevant policy clause
• Supporting medical documents
• Copies of previous communication

Keep the complaint concise and evidence-based.

Escalating the Complaint to IRDAI’s Bima Bharosa

If the insurer does not resolve the complaint within the prescribed timeline or you are dissatisfied with its response, you can approach Bima Bharosa, IRDAI’s grievance platform.

Bima Bharosa allows policyholders to register and track complaints. A token number is generated after successful registration, and the complaint status can be monitored through the portal.

The Bima Bharosa complaint form accepts a claim number for claim-related complaints and allows supporting documents to be uploaded.

What Information Should You Upload?

Keep relevant documents ready, such as:

• Policy document
• Claim rejection letter
• Claim form
• Medical reports
• Hospital bills
• Discharge summary
• Insurer correspondence
• Grievance complaint and response

Upload only relevant documents and avoid sharing unnecessary personal information.

Can You Approach the Insurance Ombudsman?

Yes, the Insurance Ombudsman is another grievance-redressal mechanism available for eligible insurance disputes.

IRDAI’s Bima Bharosa FAQ provides information about approaching the Insurance Ombudsman and directs policyholders to the Council for Insurance Ombudsmen for Ombudsman centre details.

The Ombudsman route has its own eligibility conditions, jurisdiction and procedural requirements, so check the current rules before filing.

Cashless Claim Rejected: What Should You Do?

A cashless claim rejection does not necessarily mean that the medical treatment itself is permanently excluded.

In some situations, cashless authorisation may not be approved because the insurer or TPA does not have sufficient information to determine admissibility at that stage.

Ask for:

1. The written reason for cashless denial
2. The policy clause involved
3. The documents required
4. Whether reimbursement claim submission is possible
5. The deadline and procedure for reimbursement

If you subsequently pay the hospital bill yourself, preserve all original documents required for a reimbursement claim.

Whether reimbursement is available depends on the policy terms and the reason for cashless denial.

Health Insurance Claim Rejected Due to Document Issues

Document-related rejection can sometimes be addressed by supplying the missing information.

For example, if the insurer requests a medical report that was not initially submitted, provide the report and ask for the claim to be reassessed.

Maintain a document checklist:

Document	Why It May Be Required
Discharge summary	Confirms admission, diagnosis and treatment
Final hospital bill	Shows total treatment expenses
Detailed bill	Provides expense-wise breakup
Investigation reports	Supports diagnosis and treatment
Prescription	Establishes medical advice
Pharmacy bills	Supports medicine expenses
Claim form	Provides claim details
Payment receipts	Supports expenses paid
Policy document	Establishes coverage terms

The exact requirements vary by policy and claim.

Can a Rejected Claim Be Reopened?

It can be possible to request reconsideration when new documents, clarification or evidence addresses the reason for rejection.

For example, if a claim was rejected because the insurer believed a particular condition was pre-existing, medical records may help clarify when the condition was actually diagnosed.

However, submitting additional documents does not automatically mean the insurer must approve the claim. The claim will still be assessed against the applicable policy terms.

What Not to Do After a Claim Rejection

Do Not Ignore the Rejection Letter

The letter can contain the reason and policy clause that you need to challenge.

Do Not Submit Fake or Altered Documents

Never modify medical records, bills or reports to support a claim.

Do Not Depend Only on Phone Calls

Keep important communication in writing.

Do Not Send Unrelated Documents

Provide documents relevant to the specific claim issue.

Do Not Assume Every Rejection Is Final

Review the reason and follow the available grievance process.

Do Not Miss Applicable Deadlines

Check the policy and relevant grievance procedures for any time limits.

Health Insurance Claim Rejection: Simple Action Plan

You can follow this sequence:

Claim rejected → Get written reason → Check policy clause → Collect supporting documents → Request reconsideration → Approach insurer’s GRO → Bima Bharosa, if required → Insurance Ombudsman, where eligible

This creates a documented record of your complaint and response.

How long does an insurer have to resolve a grievance?

IRDAI’s Bima Bharosa FAQ states that an insurer should resolve a grievance within 15 days of receiving it.

Can I complain to IRDAI directly?

Bima Bharosa provides a mechanism for policyholders to register complaints and escalate unresolved or unsatisfactory grievances after approaching the insurer’s grievance mechanism.

Is claim rejection the same as claim repudiation?

The terms can be used differently depending on the insurer and context. What matters for the policyholder is the written decision, the reason given and the specific policy provision relied upon.

Conclusion

A rejected health insurance claim should not be treated as the end of the process without first understanding the reason.

Start by obtaining the rejection decision in writing, checking the relevant policy clause and collecting the medical and financial documents supporting your claim. If you believe the decision is incorrect, request reconsideration and use the insurer’s formal grievance mechanism.

If the issue remains unresolved, Bima Bharosa provides an IRDAI grievance channel, while the Insurance Ombudsman may be available for eligible disputes. Keeping complete records of the claim, documents and correspondence can make the grievance process easier to follow.
