Reimbursement Claim Denied in India? How to Appeal Your Health Insurance Rejection

Reimbursement claims arise when you pay for hospitalisation out of pocket — either because the hospital was not in the insurer's cashless network, or because cashless authorisation was declined, or by your own choice — and then seek reimbursement from your insurer. Despite having a valid health insurance policy, many Indian policyholders find their reimbursement claims rejected partially or entirely. This guide explains why it happens and how to fight the denial.

How Reimbursement Claims Work in India

Under a reimbursement claim, you:

1. Pay the hospital bills directly
2. Collect all original documents after discharge
3. Submit the claim to your insurer or TPA within the prescribed time limit (typically 30 to 60 days from discharge)
4. The insurer reviews and settles the claim — or rejects it

Key TPAs handling reimbursement claims for Indian insurers include Medi Assist, Health India, Vidal Health, and MD India. These TPAs review documents on behalf of the insurer and recommend approval or rejection.

Common Reasons Reimbursement Claims Are Denied

Documentation issues:

• Missing original bills, discharge summary, or investigation reports
• Bills not on the hospital's letterhead or not stamped and signed by the hospital
• Incomplete claim form or missing declaration pages
• Delay in claim submission beyond the policy's time limit

Coverage and exclusion issues:

• Treatment classified as a pre-existing disease (PED) within the waiting period
• Procedure listed as a specific exclusion in the policy (cosmetic, dental, etc.)
• Hospitalisation argued as medically unnecessary (outpatient-level treatment)
• Non-network hospital claimed without emergency justification (for plans that require network hospitalisation)

Clinical assessment disputes:

• The insurer's medical officer disputes the treating doctor's diagnosis
• The hospitalisation duration is questioned as excessive
• The procedure cost is argued to be above standard rates

Administrative issues:

• Claim filed after the policy lapsed (premium not paid)
• Incorrect patient name, age, or policy number on documents
• Mismatch between the diagnosis and the treating department

Step 1: Understand the IRDAI 30-Day Settlement Rule

Under the IRDAI (Health Insurance) Regulations 2016, insurers must settle a reimbursement claim within 30 days of receiving all required documents. If the insurer requires additional information or documents, they must request it within 15 days of receiving the initial claim.

If your claim has not been decided within 30 days of submitting complete documents, the insurer is in violation of IRDAI regulations — and this is a separate ground for complaint.

Step 2: Obtain the Rejection Letter

Request a formal written rejection letter from your insurer or TPA. This letter must:

• Identify the specific policy clause or exclusion being invoked
• State the clinical or administrative reason for rejection
• Inform you of your grievance rights

Without this letter, you cannot effectively appeal. If the TPA issued the rejection, confirm whether the insurer has independently reviewed the decision, as TPA rejections can be overturned.

Step 3: File an Internal Grievance with the Insurer's GRO

Write a formal grievance to your insurer's Grievance Redressal Officer (GRO). Under the IRDAI (Protection of Policyholders' Interests) Regulations 2017, the GRO must:

• Acknowledge your complaint within 3 working days
• Resolve it within 15 days

Your grievance letter should:

• Reference the policy number and claim number
• Attach the rejection letter and all medical documentation
• Specifically rebut each ground for rejection
• Cite the relevant IRDAI regulation if the TAT was breached

Step 4: Escalate to IGMS

If the GRO does not resolve within 15 days, or if you are dissatisfied, file on the IGMS portal at igms.irda.gov.in.

• Select your insurer from the dropdown
• Choose "Claim Rejection" as the complaint type
• Upload all supporting documents
• Submit and retain your complaint reference number

Alternatively, call BIMA BHAROSA at 1800-4254-732 (toll-free) to file by phone.

Step 5: Insurance Ombudsman

For a binding resolution, file with your regional Insurance Ombudsman. India has 17 offices covering all states. Key facts:

• No filing fee
• Awards up to ₹30 lakh (health insurance)
• Binding on the insurer
• Decision within 3 months
• No lawyer required

The Ombudsman regularly handles reimbursement claim disputes and rules in favour of policyholders where insurers cannot justify the rejection with specific policy provisions.

Step 6: Consumer Court

For amounts above ₹30 lakh, or as an alternative legal route, file before:

• District Consumer Commission — up to ₹50 lakh
• State Consumer Commission — ₹50 lakh to ₹2 crore
• National Commission (NCDRC) — above ₹2 crore

Building Your Appeal: Document Checklist

Assemble the following for your GRO complaint and Ombudsman filing:

• Policy document and certificate of insurance
• Rejection letter from insurer or TPA
• Complete hospitalisation records: admission notes, discharge summary, indoor case papers
• All diagnostic reports (blood tests, imaging, pathology)
• Original bills and payment receipts (hospitalisation, pharmacy, investigations)
• Treating doctor's certificate and prescription
• Claim form (copy of what you submitted)
• Any prior correspondence with the insurer or TPA

Common Appeals That Succeed

• TAT violation appeals — If the insurer exceeded the 30-day settlement timeline, file an IGMS complaint citing the specific regulation
• PED moratorium — If the policy has been continuous for 8 years, cite the moratorium period to defeat PED exclusions
• Inadequate disclosure of exclusions — If the exclusion was not clearly disclosed at policy inception, courts and Ombudsman offices regularly reject the insurer's reliance on it
• TPA error — Document discrepancies caused by the TPA rather than genuine policy violations are routinely corrected on appeal
