Health Insurance Claim Rejected? Common Reasons & How to Fix It

Getting your health insurance claim rejected can be frustrating, especially when you're already dealing with a medical emergency. However, a rejected claim doesn't mean the end — you have the right to appeal, escalate to IRDAI, and even approach the Insurance Ombudsman. This guide explains the most common rejection reasons and the exact steps to fix them.

What is a Health Insurance Claim Rejection?

A claim rejection occurs when your health insurer refuses to pay for a hospitalisation or medical treatment that you believed was covered under your policy. The insurer must provide a written reason for the rejection. Under IRDAI regulations, you have the right to appeal any rejected claim.

Important: There is a difference between claim rejection (denied entirely) and claim repudiation (partially denied or reduced). Both can be appealed.

Common Reasons for Health Insurance Claim Rejection

1. Pre-Existing Disease (PED) Not Disclosed

If you did not disclose a pre-existing condition at the time of buying the policy, the insurer can reject claims related to that condition. IRDAI mandates a waiting period of up to 48 months for PEDs.

2. Waiting Period Not Over

Most policies have waiting periods:

• Initial waiting period: 30 days (no claims except accidents)
• Specific disease waiting period: 2-4 years for conditions like hernia, kidney stones, etc.
• PED waiting period: Up to 48 months

3. Excluded Treatment or Procedure

Certain treatments are excluded from standard health insurance policies:

• Cosmetic surgery
• Dental treatment (unless due to accident)
• Self-inflicted injuries
• Infertility treatment
• Experimental treatments

4. Policy Lapsed Due to Non-Payment

If your premium was not paid on time and the grace period expired, your policy lapses and claims will be rejected.

5. Wrong or Incomplete Documentation

Missing discharge summary, bills, prescriptions, or diagnostic reports can lead to rejection.

6. Treatment at Non-Network Hospital (for Cashless Claims)

Cashless claims are only valid at network hospitals. If you visited a non-network hospital, you must file a reimbursement claim instead.

7. Sub-Limits Exceeded

Some policies have sub-limits on room rent, specific treatments, or doctor fees. If your expenses exceed these limits, the excess amount is rejected.

8. Claim Filed After Deadline

Most insurers require claim intimation within 24-48 hours of hospitalisation and final claim submission within 15-30 days of discharge.

How to Appeal a Rejected Health Insurance Claim

Step 1: Get the Rejection Letter

Request a written rejection letter from your insurer with specific reasons for denial. This is your right under IRDAI regulations.

Step 2: Review Your Policy Document

Check your policy wording carefully. Compare the rejection reason against the actual terms, exclusions, and waiting periods in your policy.

Step 3: Gather Supporting Documents

Collect all relevant documents:

• Policy document and certificate
• Claim rejection letter
• Hospital discharge summary
• All medical bills and receipts
• Doctor's prescriptions and diagnosis reports
• Diagnostic test reports (blood tests, scans, etc.)
• Previous medical records (if PED-related)
• Correspondence with insurer

Step 4: Write a Formal Appeal to the Insurer

Send a written appeal (email + registered post) to the insurer's grievance cell:

• Quote your policy number and claim number
• State the rejection reason and why you disagree
• Attach supporting documents
• Request re-evaluation of your claim

Timeline: The insurer must respond within 15 days of receiving your grievance.

Step 5: Escalate to IRDAI (If Insurer Doesn't Resolve)

If the insurer does not resolve your complaint within 15 days, escalate to IRDAI:

Online: File a complaint on the IRDAI Integrated Grievance Management System (IGMS) at igms.irda.gov.in

Toll-free: Call IRDAI at 155255 or 1800-4254-732

Email: complaints@irdai.gov.in

Step 6: Approach the Insurance Ombudsman

If IRDAI intervention doesn't help and the claim amount is up to ₹50 lakh, you can approach the Insurance Ombudsman:

• File a complaint within 1 year of the insurer's final rejection
• The Ombudsman must pass an order within 3 months
• The decision is binding on the insurer (not on you — you can still go to court)

Step 7: Consumer Court (Last Resort)

If all else fails, file a complaint with the Consumer Disputes Redressal Commission:

• District Forum: Claims up to ₹1 crore
• State Commission: Claims ₹1 crore to ₹10 crore
• National Commission: Claims above ₹10 crore

Important Tips

1. Always disclose pre-existing conditions when buying or renewing your policy — non-disclosure is the #1 reason for claim rejection
2. Intimate the insurer within 24 hours of hospitalisation, even for emergency admissions
3. Keep all original bills and reports — submit photocopies first if needed, but keep originals safe
4. File reimbursement claims within the deadline mentioned in your policy (usually 15-30 days from discharge)
5. Read your policy document thoroughly — understand exclusions, sub-limits, and waiting periods before you need to make a claim

Frequently Asked Questions

Q1. Can I appeal a health insurance claim rejection?

Yes. You have the right to appeal any rejected claim. First appeal to the insurer's grievance cell, then escalate to IRDAI, Insurance Ombudsman, or Consumer Court if needed.

Q2. How long does the insurer have to settle or reject a claim?

Under IRDAI guidelines, the insurer must settle or reject a cashless claim within 1 hour for pre-authorisation and 3 hours for final settlement. For reimbursement claims, the insurer must settle within 30 days of receiving all documents.

Q3. What if my claim was rejected due to a pre-existing disease I didn't know about?

If you genuinely did not know about the condition, provide supporting medical records showing no prior diagnosis or treatment. The Ombudsman may rule in your favour if you can prove good faith.

Q4. Is there a fee to file a complaint with IRDAI or the Ombudsman?

No. Filing complaints with IRDAI (via IGMS portal) and the Insurance Ombudsman is completely free.

Q5. Can the insurer reject a claim for emergency hospitalisation at a non-network hospital?

No. For genuine emergencies, the insurer must process reimbursement claims even if the hospital is not in their network. However, cashless facility won't be available.

Q6. What happens if the insurer doesn't respond to my grievance within 15 days?

You can directly escalate to IRDAI via the IGMS portal or approach the Insurance Ombudsman. The insurer's non-response strengthens your case.

Q7. Can I claim the rejected amount in the next policy year?

No. Rejected claims cannot be rolled over. However, if the rejection was wrong and you win an appeal, the insurer must pay the original claim amount with interest.
