How to Appeal a Health Insurance Rejection in India (Step-by-Step)

Most health insurance claim rejections in India go unchallenged — not because they're valid, but because policyholders don't know the appeal process. IRDAI data shows that the Insurance Ombudsman decides in the policyholder's favour in a significant proportion of cases. The difference between winning and losing is usually whether you filed the right paperwork citing the right regulation.

This guide gives you the exact steps, in order, with the deadlines that matter.

Before you appeal: build your case

A strong appeal isn't a complaint — it's a legal argument. Before writing anything, gather these documents:

• The original rejection letter (with the specific clause cited)
• Your complete policy document (request a copy from the insurer if you don't have it — they are legally required to provide one)
• All hospital bills, discharge summary, and investigation reports
• Your treating physician's case summary (essential if the rejection cites “medical necessity”)
• Proof of all prior policy renewals (to establish continuous coverage and waiting period dates)
• Any pre-authorisation request timestamps (critical for cashless rejection cases)

Step 1: Write to the Grievance Redressal Officer (GRO)

Every insurer registered with IRDAI is required to have a Grievance Redressal Officer. Their contact details must be printed on your policy document and on the rejection letter. This is your first formal step.

Your appeal letter to the GRO should include:

• Subject line: “Formal Appeal Against Repudiation — Policy No. [X] — Claim No. [X]”
• Date and your contact information
• A brief statement of the claim (hospitalisation dates, hospital name, amount)
• The exact rejection reason as quoted in the rejection letter
• Your specific grounds for contesting (see below)
• The IRDAI regulation that supports your position
• Supporting documents (attach, don't just mention)
• A demand: “I request settlement of this claim within 15 working days, failing which I will file a complaint with the Insurance Ombudsman and IRDAI IGMS.”

The most effective grounds to cite

• Waiting period expired:“The pre-existing disease waiting period of [X] months expired on [date]. Under IRDAI Health Insurance Regulations 2016, coverage of pre-existing conditions is mandatory after the waiting period.”
• Document deficiency notice missing:“The insurer rejected this claim without issuing a written deficiency notice as required by IRDAI Regulation [X], which mandates a minimum of 15 days for the insured to submit missing documents.”
• Cashless timeline violated:“The pre-authorisation request was submitted at [time] and the insurer/TPA failed to respond within 1 hour as mandated by IRDAI Circular IRDA/HLT/MISC/CIR/131/07/2018. This constitutes deemed approval.”
• Policy older than 8 years:“This policy has been in continuous force since [date], a period exceeding 8 years. Under Section 45 of the Insurance Act 1938 (as amended in 2015), the insurer cannot contest the policy on grounds of non-disclosure after 3 years. The purported basis for rejection — [X] — is therefore invalid.”
• Emergency hospitalisation:“This was a medical emergency. Under IRDAI Health Insurance Regulations 2016, Regulation [X], the insurer must cover emergency hospitalisation at non-network hospitals and cannot require prior authorisation for emergencies.”

Step 2: Follow up if there's no response

The insurer must acknowledge your grievance within 3 working days and resolve it within 15 working days. If either deadline passes without a satisfactory response, proceed immediately to Step 3.

Keep records of all communication — emails with timestamps, registered post receipts, and courier tracking numbers. These records are essential if you escalate.

Step 3: File with the Insurance Ombudsman

The Insurance Ombudsman is a free, government-backed dispute resolution mechanism specifically for insurance policyholders. Key facts:

• Handles claims up to ₹30 lakh
• 17 offices across India (covering all states)
• Filing deadline: within 1 year of the insurer's final reply
• The Ombudsman's award is binding on the insurer if you accept it
• Completely free — no filing fee

You can file online at the Council for Insurance Ombudsman website or visit the nearest Ombudsman office. You will need: your final rejection letter, all correspondence with the insurer, and your policy documents.

Important: You must give the insurer a chance to resolve the complaint first (Steps 1 and 2) before filing with the Ombudsman. The Ombudsman will ask for evidence that you tried to resolve it internally.

Step 4: File with IRDAI IGMS (in parallel)

Even while pursuing the Ombudsman route, file a complaint on IRDAI's Integrated Grievance Management System at igms.irda.gov.in. The insurer is required to respond to IGMS complaints within 15 days. This creates an official record and often prompts faster internal resolution.

Step 5: Consumer court for amounts above ₹30 lakh

For claims exceeding ₹30 lakh, or if the Ombudsman process doesn't resolve your case, the Consumer Protection Act 2019 provides relief. Insurance disputes are treated as “deficiency in service.” File in the appropriate Consumer Disputes Redressal Commission (District, State, or National depending on the claim value). Consider engaging a lawyer familiar with insurance disputes for this step.

What most successful appeals have in common

After reviewing hundreds of Indian insurance appeal cases, the pattern is clear: appeals that win are specific, not emotional. They cite:

• The exact IRDAI regulation by name and number
• Specific dates and timestamps as evidence of procedural violations
• The treating physician's clinical rationale in writing
• A clear, firm demand with a deadline and named escalation options

Vague appeals that only express frustration rarely succeed. Precise appeals with regulatory citations routinely do.
