Health insurance claim rejected? Your complete, step-by-step action plan

A rejection letter is not written to be read; it is written to be filed. But somewhere in it is a specific clause number and a specific stated reason — and that reason determines your entire strategy. Insurers must give the reason in writing. If yours didn't, that itself is your first grievance.

First, breathe — then read the rejection letter properly

The stated reason will almost always be one of four:

1. Non-disclosure of a pre-existing condition

The most common rejection of all. You (or whoever filled the proposal form) didn't mention a condition — and it doesn't have to be dramatic. A thyroid imbalance, PCOS noted in an old prescription, a blood-pressure reading from years ago: insurers' claim teams look for anything in your hospital records that predates the policy and wasn't declared. This is also the most contestable category — especially if the undisclosed condition has nothing to do with the illness you claimed for, or if the policy has run past the moratorium period after which insurers' ability to contest non-disclosure narrows sharply.

2. Waiting period not completed

Specific conditions (and maternity) carry their own waiting periods, and pre-existing diseases carry one too — now capped at 3 years, reduced from 4, under IRDAI's recent policyholder reforms. If the insurer counted waiting period wrongly — common when you've ported from another insurer, because your completed waiting time must carry over — this is very winnable.

3. Sub-limits and caps

Technically a partial payment rather than a rejection, but it produces the same shock: the policy paid, just far less than the bill, because a cap inside the policy (room rent, specific procedure, maternity) quietly limited it. If this is you, the appeal route is the same, but the argument is different — check what the policy actually caps before you write your appeal.

4. Exclusions and consumables

Gloves, syringes, "non-medical items," specific excluded treatments. Small individually, they add up to real money — and hospitals' itemised bills often misclassify items that are actually payable.

The escalation ladder: four rungs, in strict order

Rung 1 — The insurer's Grievance Redressal Officer (GRO)

Every insurer is required to have one, with contact details on its website and in your policy document. Write — email, not phone — stating your policy number, claim number, the rejection reason given, and why you dispute it, attaching your evidence. Two practical rules: always create a paper/email trail (phone calls don't exist, in appeal terms), and ask explicitly for a written response. The insurer's grievance machinery generally has to acknowledge quickly and resolve within about 30 days. Roughly half of disputed rejections die here, quietly reversed — claim teams apply rules mechanically; grievance teams apply judgment.

Rung 2 — Bima Bharosa (IRDAI's grievance portal)

If 30 days pass without resolution, or the answer is an unsatisfying no, register the complaint on Bima Bharosa (bimabharosa.irdai.gov.in) — IRDAI's online grievance system. This does two things: it puts your complaint on the regulator's tracked record (insurers report grievance statistics to IRDAI, and unresolved complaints have supervisory consequences), and it timestamps your escalation. Upload your GRO correspondence; the portal routes the complaint back to the insurer with a regulator's deadline attached.

Rung 3 — The Insurance Ombudsman (the rung nobody uses, and should)

This is the most underused consumer right in Indian insurance. The Ombudsman (policyholder.gov.in/ombudsman) is an independent authority with offices across India, and it is designed for exactly your situation:

Complaints are meant to be disposed of within about three months of receiving all requirements. And here is the fact this entire article exists to tell you:

People lose winnable cases not on merit but on this clock — they spend fourteen months politely re-emailing the insurer, then discover the window has closed. Mark the date of the final rejection letter the day it arrives, and count forward twelve months. That is your real deadline, and every step above should be paced inside it.

Rung 4 — Consumer Commission (court, but the consumer-friendly kind)

If the Ombudsman route fails or your claim exceeds its limits, the consumer commissions (District/State/National) remain open, with their own two-year limitation period from the cause of action. You'll want professional help at this stage — but the vast majority of legitimate claims never need to travel this far.

Your document checklist (gather once, use at every rung)

Policy document and schedule; the complete rejection letter; discharge summary; all itemised hospital bills and payment receipts; investigation reports; your proposal form (ask the insurer for a copy — you're entitled to it, and it's often where non-disclosure disputes are won); every email exchanged; and a one-page timeline of events in your own words. The one-page timeline is the most persuasive document in the file — grievance officers and Ombudsman staff read hundreds of files; the complainant who makes the story effortless to follow starts ahead.

Three recent rule changes working in your favour

Recent IRDAI policyholder reforms tightened the rules in your favour: cashless claims must now be decided fast — with final authorisation within three hours of discharge request from the hospital; the pre-existing disease waiting period is capped at three years; and after the moratorium period (60 months of continuous coverage), a claim can no longer be contested for non-disclosure except in cases of established fraud. If your rejection cites a ground these reforms have narrowed, say so explicitly in your GRO letter.
