Health insurance claims: understanding the paperwork

Almost all confusion about health insurance paperwork comes from treating it as one process. There are two, they work in opposite directions, and they need different documents at different times.

In a cashless claim the insurer or its third-party administrator settles with the hospital directly, so the paperwork happens before and during the admission, and it is largely generated by the hospital. Your role is mainly to identify yourself and your policy correctly at the outset and to keep copies of what passes through.

In a reimbursement claim you pay the hospital and then claim the amount back, so the paperwork happens after discharge and it is largely your responsibility to assemble. This is the route for treatment at a hospital outside the insurer's network, and for expenses that fall outside a cashless arrangement.

The practical difference in difficulty is worth stating plainly: a reimbursement claim requires a complete document set produced by you, after the fact, from papers you may or may not have collected while attending to something more pressing. That is the reason the habits below matter, and the reason the single most useful one — keeping a copy of everything before it is handed over — costs nothing at the time and cannot be recovered later.

This explains what the paperwork consists of and how the process works. It is not advice on any policy or claim.

The sequence is fixed, and knowing it makes it possible to tell whether something has stalled.

It begins with identification at admission: the policy or health card, the administrator's details, and identity proof, so that the hospital's insurance desk can raise a request against the right policy.

The hospital then submits a pre-authorisation request to the insurer or administrator, setting out the proposed treatment and estimated cost. The insurer decides on that request and communicates an authorisation, a query, or a rejection. Where a query is raised, the hospital responds, and this is where delays typically sit.

At discharge the hospital submits a final authorisation request with the actual bill, and the insurer authorises the final settled amount. Anything not covered — non-payable items, amounts above limits, deductions under policy terms — is payable by the patient at that point.

The Insurance Regulatory and Development Authority of India has prescribed timelines for this. Under its master circular on health insurance business dated 29 May 2024, an insurer is required to decide on a cashless authorisation request within one hour of receiving it, and to grant final authorisation on a discharge request within three hours, with the stated intention that a policyholder should not be kept waiting for discharge.

Because circulars are amended, the current text is the authority on the exact periods.

Here the order reverses: treatment, payment, then the claim.

Most policies require intimation to the insurer within a period specified in the policy — sooner for a planned admission, and within a stated time after admission in an emergency. The period is set by the policy wording rather than by a general rule, and intimation is a separate step from filing the claim. Delay in intimation is a common and avoidable source of difficulty, so the number to have is the one in your own policy document.

The claim itself is then filed with a completed claim form and the document set described below, within the period the policy allows after discharge.

The insurer or administrator assesses the claim and either settles it, raises a query for further documents, or rejects it with reasons. A query restarts the clock in practice, because assessment resumes when the last required document is received — which is precisely why a complete first submission is worth more than a fast one.

Regulatory timelines apply to the insurer's decision after a complete set of documents has been received, and they are set out in the applicable IRDAI regulations and master circular. The specific period should be read from the current instrument rather than taken from a summary, since these have been revised.

What determines whether a claim is payable at all is the policy wording, not the paperwork — and that is a separate question from whether the file is complete.

The list is reasonably stable across insurers, though the exact requirements are the insurer's own and are stated in the policy and claim form.

The completed and signed claim form, in the insurer's own format.

The discharge summary. This is the central document in any hospitalisation claim, because it records the admission, what was done and when the patient was discharged. A claim without it does not progress.

The final hospital bill with an itemised break-up, and the payment receipts. A consolidated figure without a break-up is routinely queried, because the assessment works item by item against the policy.

Investigation and diagnostic reports relating to the admission, and the bills for them.

Prescriptions and pharmacy bills, which have to correspond to each other — a pharmacy bill without the prescription supporting it is a frequent cause of a deduction.

The pre-authorisation approval, where the claim began as a cashless one.

Identity proof, the policy document or card, and the customer verification documents the insurer requires.

Bank details for payment, usually with a cancelled cheque or a passbook copy.

And, where relevant, the police report for an accident case, or any specific document the policy names for a particular category.

One missing item stops the whole claim rather than the part it relates to, because assessment resumes only when the file is complete.

There is one practice that matters more than every other item of advice about claim paperwork, and it takes minutes.

Before any document is handed to a hospital insurance desk, an administrator or an insurer, photograph or scan it. All of it: the claim form as completed and signed, every bill, the discharge summary, every report, the covering letter, and the list of what was submitted.

The reason is structural rather than pessimistic. Originals are frequently required and are not returned. Once submitted, the claimant no longer holds the record of what they claimed for, which becomes a problem in exactly the situations where it matters most — a deduction that needs to be questioned, a query about a document you believe was included, a resubmission, or a subsequent claim against a different policy for the same treatment.

Alongside the copies, keep the submission record: the date, the mode, to whom, and the acknowledgement or claim reference number. A claim reference converts every later enquiry from a description into a lookup.

And keep the correspondence in the same place, in date order — queries received, responses sent, and any partial settlement statement showing what was deducted and why. The settlement statement is the document that explains a shortfall, and it is the starting point for any question about one.

Filed together, these become the record of the claim, which is a distinct thing from the medical records of the treatment.

It is worth knowing the structure of what follows, while being clear that whether a particular claim ought to have been paid is a question about the policy wording and the facts, and not something a general explanation can assess.

The first step is the reason. A deduction or rejection is communicated with reasons, and the settlement statement or rejection letter identifies which items were disallowed and on what basis — a policy exclusion, a sub-limit, a waiting period, a non-payable item, or a document not received. Reading precisely which ground was applied is what determines everything after, because a missing-document ground and an exclusion ground lead in entirely different directions.

Insurers are required to have a grievance redressal mechanism, and raising a grievance with the insurer's own grievance officer is the first formal escalation. IRDAI operates a policyholder grievance platform for complaints not resolved by the insurer.

Beyond that, the Insurance Ombudsman mechanism established under the Insurance Ombudsman Rules provides a forum for specified categories of complaint, subject to conditions including monetary limits and time periods, and generally requires the insurer's own process to have been exhausted first.

Separately, whether a consumer complaint is available depends on the definition of a consumer and its own limitation period.

Each of these routes has its own conditions and time limits set out in the applicable rules, which are the source to work from — and where a substantial amount turns on the construction of a policy clause, that is a question for a professional.
