A rejected health insurance claim feels like the end of the road. In India, it is usually the start of an appeal that the policyholder wins more often than not.
The cancer treatment is over and the discharge papers are signed, but the hospital will not release the patient until the insurer pays. The Third-Party Administrator then denies the cashless request, and the family scrapes together four lakh rupees from savings, fixed deposits, and relatives. The patient recovers at home while the family files for reimbursement and waits the usual thirty days.
Then a message asks for Indoor Case Papers and certificates that are hard to obtain weeks after discharge, and the claim is rejected outright. The money is already gone. Yet this is recoverable. A repudiated claim is not a final ruling, and the grievance system, by the regulator's own figures, sides with policyholders more often than insurers.
Read the Repudiation Letter
A rejected claim arrives as a written repudiation letter from the insurer or its Third-Party Administrator, which by IRDAI rules must state the reason and quote the policy clause relied on. Three things matter: the claimed amount against the allowed amount, showing what was refused and whether the repudiation is total or partial; the reason codes behind each item; and the policy clause cited, checked against your own schedule and the IRDAI Master Circular. Note the clock: you have one year from the
final rejection to approach the Insurance Ombudsman, so move briskly.
Identify the Type of Denial
Every denial is one of three types, each calling for a different reply.
Administrative or technical. A paperwork error: a missing document, a typo, a late submission. Supply what is missing, correct it, or show the hospital filed late, not you.
Medical or clinical. The insurer's medical team disputes whether treatment was necessary. Answer with a clinical justification letter explaining why the chosen treatment was right and the alternatives unacceptably risky.
Policy exclusion or contractual. The insurer says the policy does not cover the condition. Prove it was not pre-existing, or that the exclusion was never disclosed at sale, itself a breach of IRDAI rules.
Challenge the Reasons That Can Be Challenged
Many refusals look like settled fact but rest on judgement, and can be contested.
Hospitalisation is not justified. Often generated by software or a reviewer who never saw the patient; meet it with proof the treatment is standard care, plus the admission trail of lab reports, vitals charts, and nursing logs.
Experimental or unproven. The IRDAI Master Circular bars blanket denial of modern treatment; back your case with peer reviewed studies showing the procedure is standard practice.
Out of network. The rule does not apply in an emergency, so produce the admission notes; and since January 2024 Cashless Everywhere requires cashless treatment at any registered hospital, not only empanelled ones.
Build an Airtight File
A complete file saves weeks of back and forth. Before writing a word of appeal, gather the discharge summary, daily doctor's notes, and Indoor Case Papers; match every line of the hospital bill to a diagnostic report; and obtain a letter of medical necessity on hospital letterhead, stamped and signed. Confirm cover against the IRDAI Master Circular, assemble studies establishing the treatment as standard practice, and keep a dated log of every call and meeting, with reference numbers.
Climb the Escalation Ladder
India gives you a free, structured path. Climb the rungs in order, keeping your file moving.
The Insurer's Grievance Cell
Write a fact-based letter rebutting the repudiation point by point, with your file attached, addressed to the insurer's Grievance Redressal Officer. Where the dispute is clinical, ask for review by a doctor of the same specialty as your treating physician.
The Regulator's Portal
If the cell rejects you or stays silent, escalate through IRDAI's Bima Bharosa portal at bimabharosa.irdai.gov.in, where insurers must resolve complaints within a fixed window. In 2024 to 2025 it handled over two and a half lakh complaints, with only about four thousand eight hundred breaching the limit.
The Insurance Ombudsman
Still unsatisfied, take it to the Insurance Ombudsman, or Bima Lokpal: an independent quasi-judicial body with seventeen offices, free, needing no lawyer, deciding within three months, approached within one year of the rejection. The award binds the insurer but not you, with a daily penalty for non-compliance. Beyond it lies the Consumer Court, open if the ruling goes against you or the claim exceeds the Ombudsman's limit.
Why Persistence Pays
Many families give up before reaching the Ombudsman, which is exactly why the numbers matter. In 2023 to 2024 the Council for Insurance Ombudsmen issued 9,287 awards for complainants against 8,638 for insurers, and counting conciliated settlements, more than half of disposed complaints ended in the policyholder's favour.
The first rejection usually cites the most defensible ground available, and sustained, documented pressure reverses many of them.
The denial letter is not the final word. The appeal is slow and tiring, but the system is free, structured, and built to favour the policyholder who refuses to give up. Read the letter, build the file, and climb the ladder one rung at a time.
Frequently Asked
The hospital will not discharge the patient until I pay, because cashless approval is delayed. Is there a time limit on the insurer?
Yes. Under the IRDAI Master Circular of 2024, the insurer or TPA must decide a cashless request within one hour and authorise final discharge within three hours of the hospital's complete request; miss it and the insurer bears the extra cost. Ask the hospital for its submission timestamp as proof of breach.
My claim was rejected for a pre-existing disease I did not declare. Can they do this after years of cover?
It depends on the policy's age. Under five years, the insurer can refuse for an undisclosed pre-existing condition. After five continuous years with the same insurer, the moratorium applies and a claim cannot be rejected for non-disclosure unless deliberate fraud is proven.
