Health Insurance Claim Rejected in India? Here's What to Do Next

Getting a health insurance claim rejected after a hospitalisation is one of the most stressful things that can happen to an Indian policyholder. You bought the policy in good faith, you paid your premiums, and now — when you need it most — the insurer says no.

But here's what most people don't know: a rejection letter is not the final word.IRDAI (the Insurance Regulatory and Development Authority of India) has put in place strong regulations that protect policyholders — and insurers routinely issue rejections that don't hold up when challenged.

Step 1: Read the rejection letter carefully

Your first task is to understand exactly why your claim was rejected. The insurer is legally required to give you a written reason that cites a specific policy clause. Look for:

• The clause number cited (e.g., “Clause 4.2 — Pre-existing Disease Exclusion”)
• The specific reason given (non-disclosure, waiting period, medical necessity, etc.)
• The date of the rejection letter
• A grievance redressal address or email

If the letter does not cite a specific clause or gives only a vague reason like “not covered”, that itself may be grounds for a complaint — IRDAI requires insurers to give clear, specific rejection reasons.

Step 2: Check the IRDAI timelines

Under the IRDAI Health Insurance Regulations 2016, insurers are bound by strict timelines:

• Cashless pre-authorisation: The insurer or TPA must respond within 1 hour of receiving the request. No response within 1 hour = deemed approval.
• Discharge authorisation: Must be given within 3 hours.
• Reimbursement claims: The insurer must settle or reject within 30 days of receiving all required documents.
• Document deficiency notice: If documents are incomplete, the insurer must notify you in writing and give you at least 15 days to submit the missing documents. They cannot reject the claim without this notice.

If the insurer violated any of these timelines, that is itself a procedural ground for appealing the rejection.

Step 3: Compare the cited clause against your policy

Pull out your actual policy document and find the clause the insurer cited. Read it word for word. Insurers sometimes misquote, misapply, or selectively cite clauses. Key things to check:

• Does the clause actually say what the insurer claims it says?
• If it's a pre-existing disease exclusion — has the waiting period (usually 48 months) already expired?
• If it's a non-disclosure rejection — how old is your policy? For policies older than 8 years, the insurer cannot contest the policy under the Insurance Laws (Amendment) Act 2015, except in cases of proven fraud.

Common rejection reasons — and which ones are challengeable

Pre-existing disease (PED) exclusion

Valid only during the waiting period. Once the waiting period expires (typically 4 years), all pre-existing conditions must be covered. A rejection citing PED after the waiting period has expired is invalid.

Non-disclosure or material misrepresentation

The insurer must prove you intentionally concealed information. For minor or unknown conditions, this is hard to prove. For policies older than 8 years, contestability is severely limited regardless.

Medical necessity dispute

The insurer's medical reviewer overrides your treating physician's judgment. Under IRDAI guidelines, the treating physician's clinical assessment carries significant weight. Insurers who reject on medical necessity grounds without an Independent Medical Examination are on weak ground.

Waiting period violation

If the treatment is genuinely within a specific disease waiting period stated in your policy, the rejection may be valid. But check whether the waiting period was correctly counted from your first policy inception date (not the latest renewal).

Network / cashless rejection

In a genuine medical emergency, IRDAI mandates that insurers cover treatment at non-network hospitals. The insurer cannot require prior authorisation for emergencies.

Step 4: File an appeal with the insurer's GRO

Every insurer is required by IRDAI to have a Grievance Redressal Officer (GRO). Write a formal letter to the GRO citing:

• Your policy number and claim number
• The specific rejection reason
• Why you believe the rejection is incorrect (citing the IRDAI regulation)
• Supporting documents (medical records, policy document, correspondence)
• A demand for resolution within 15 working days

The insurer must acknowledge your grievance within 3 working days and resolve it within 15 working days under IRDAI guidelines.

Step 5: Escalate if the insurer doesn't respond

If the insurer doesn't respond within 15 working days, or you're not satisfied with their response, you have two free escalation options:

• Insurance Ombudsman:Free dispute resolution for claims up to ₹30 lakh. File within 1 year of the insurer's final reply. The Ombudsman's decision is binding on the insurer if you accept it.
• IRDAI IGMS: File a complaint at igms.irda.gov.in. The insurer must respond within 15 days. Best used when the insurer is non-responsive rather than disputing a claim amount.

For claims above ₹30 lakh, or if you want a legally binding judgment, the Consumer Protection Act 2019 allows you to file in Consumer Disputes Redressal Commissions. Insurance disputes are classified as “deficiency in service” under this Act.

The bottom line

Insurers reject claims knowing that most policyholders won't challenge them. But IRDAI regulations give you real, enforceable rights. A clear, specific appeal letter that cites the applicable regulation changes the dynamic entirely — and the Insurance Ombudsman resolves the majority of cases in the policyholder's favour when the procedural violations are clear.

Don't give up on a claim without at least checking whether the rejection is procedurally and legally sound.
