What to Do When a Health Insurance Claim Is Rejected

Meera has a letter and a bill

The claim for her father's admission has been rejected. The letter gives a reason in a sentence, the hospital bill is already paid, and Meera is trying to work out whether this is final.

It is usually not final, and the first thing to establish is which kind of rejection she is holding — because the routes diverge immediately and one of them is much easier than the other.

Find out what the reason actually is

The letter must state a reason and it is often compressed to a phrase. Ask for it in full, in writing, with reference to the specific policy clause relied on. That request alone resolves a proportion of cases, because a reason that cannot be tied to a clause is a reason that will not survive escalation.

Rejections fall into a few broad groups, and it is worth knowing which one this is.

Documentation. Missing bills, an absent discharge summary, unitemised charges, no supporting diagnostic reports. These are the most common and the most straightforwardly fixed, because the claim was never assessed on its merits — it was returned for want of paper.

Procedure. The insurer was not notified within the intimation window, or pre-authorisation was not obtained for a planned admission. Frustrating, and often reversible where the delay has a reasonable explanation.

Policy terms. A waiting period had not elapsed, a sub-limit was exceeded, the treatment sits inside an exclusion, or a room-rent limit scaled the claim down. These are the substantive ones, and whether they are arguable depends entirely on the wording.

Non-disclosure. The insurer says a condition existed before the policy and was not declared. This is the most serious category, the most consequential, and the one where the answer depends on facts rather than on argument.

Fix the easy ones first

If the reason is documentation, supply what is missing and resubmit. Ask the hospital's insurance desk for an itemised bill if what Meera has is a summary, and for any report the insurer names. Hospitals do this constantly and will usually produce it within days.

If the reason is procedural, write and explain the circumstances. An emergency admission at night, a patient unable to communicate, a family occupied with treatment rather than paperwork — these are ordinary and insurers do accept them, but only in response to a written explanation rather than a phone call.

Do all of this in writing, and keep the thread. Every subsequent stage of escalation turns on being able to show what was asked, what was answered, and when.

The substantive ones

Where the rejection rests on policy terms, what is needed is the policy wording rather than the brochure, and the specific clause the insurer relied on.

Two things are worth checking carefully. Whether the exclusion actually covers the treatment received, since exclusions are written narrowly and are sometimes applied more broadly than they read. And whether a sub-limit or room-rent limit was applied correctly, because proportional reductions are calculated in ways that are easy to get wrong and hard for a claimant to check without asking for the working.

Ask for the calculation. An insurer that has reduced a claim should be able to show how, and the request is entirely reasonable.

Where non-disclosure is alleged

This is the hardest category and deserves care rather than indignation.

Establish precisely what the insurer says was not disclosed and when they say it arose. Then look at what was actually declared on the proposal form — which, if an agent completed it, may not be what Meera's father told them.

Where a condition genuinely predates the policy and was genuinely not declared, the position is weak, and it is better to know that early. Where the condition was declared, or where the connection between it and the treatment claimed is tenuous, that is a substantive argument worth making.

The reason this category matters beyond the individual claim is preventive: it is why checking your declared history immediately after buying a policy is worth the half-hour, and why correcting an omission while healthy is enormously cheaper than defending it during a claim.

Escalating

Insurers have an internal grievance process, and it is the required first step. Use it in writing, attach the correspondence, and state plainly what you want — the claim reassessed, or the specific clause explained.

If that does not resolve it, India has an ombudsman scheme for insurance complaints, which is free to the complainant and designed for exactly this. Which forum applies and what the current eligibility and time limits are should be checked against the regulator's own material rather than taken from any article, including this one, since those rules change.

Beyond that there are consumer forums. That route is slower and more formal, and it is a genuine option for a large claim rather than a threat to be waved during a phone call.

What to do differently next time

Most of the prevention happens before anybody is unwell. Declare the medical history completely and check what was declared. Know the intimation window and use it. Keep itemised documentation for every admission, including the pre- and post-hospitalisation receipts. And understand your policy's room-rent category before choosing a room, because that single choice can scale down an entire claim.

None of that helps Meera today, and it is why what to do after buying a policy is a half-hour worth spending at purchase rather than at a hospital desk.

What to take away

A rejection is a decision by one assessor, and a large share of them are procedural rather than substantive. Get the reason in writing with the clause it relies on, and identify which of the four kinds you are dealing with.

Fix documentation and procedural rejections directly, since those are the majority and the easiest. Ask for the calculation where a claim was reduced. Escalate through the insurer's grievance process in writing, then to the ombudsman, checking the current rules from the regulator rather than from an article. And keep every piece of correspondence, because each stage rests on what the last one said.
