Health Insurance Claim Partly Paid: How to Challenge Deductions

Part of the Health Insurance Claim Recovery Series by RightToInformation.Wiki.

If your health insurance paid only part of the hospital bill, demand a written deduction sheet that shows each cut line by line with the exact policy clause behind it. Most disputed deductions, room rent linked cuts, proportionate deductions, consumables and non-medical items can be challenged through the insurer grievance officer, IRDAI Bima Bharosa, and the Insurance Ombudsman.

A “partly paid” claim is one where the insurer or Third Party Administrator (TPA) settled some of your hospital bill but cut a chunk of it without paying. The settlement letter or claim closure email usually carries a deduction sheet or settlement summary that lists every cut. This is the most common form of dispute in reimbursement claims in India, and it is also the most fixable. The insurer has a legal duty to give a reason for every single deduction, citing a specific policy clause. If the reason is missing, vague, or wrong on facts, the deduction can be challenged.

Common deduction categories you will see on a settlement summary include room rent above the policy limit, proportionate deduction across other heads, sub-limits on specific ailments, co-payment share, non-medical items like gloves and PPE kits, pre-existing condition cuts, waiting period cuts, unrelated charges, doctor's fees over a package amount, anaesthesia and OT charges over cap, registration fees, pharmacy items, and the so-called “reasonable and customary” reduction. Many of these are arbitrary or wrongly applied. The IRDAI Master Circular on Health Insurance Business dated 29 May 2024 has narrowed the room for some of these cuts. Citizens just have to know what to ask for.

1. Pull the settlement letter and the bank credit advice. Open the original hospital bill in parallel. Note the gap between what was billed and what was paid.
2. Identify every cut line item. Highlight each amount that the insurer reduced. Tag each one with a guess: room rent, proportionate, consumables, sub-limit, co-pay, unrelated.
3. Email the insurer's grievance officer and TPA. Subject line: “Deduction sheet required, Claim ID [CLAIM ID]”. Attach the original bill and a copy of the claim form. The 15 working day clock starts the moment this email goes out.
4. Demand a written breakdown listing each deduction and the exact policy clause behind it. The insurer cannot reply with “as per policy terms” alone.
5. Demand the basis of each reasonable and customary cut. Ask for comparator hospital data, not adjectives.
6. Save the settlement bank credit advice. This shows how much actually hit your account and on what date.
7. Keep all hospital bills, discharge summary, ICP (in-patient case papers), and prescriptions ready for the line-by-line challenge.
8. Mark your calendar. If no reasoned reply lands in 15 working days, file at IRDAI Bima Bharosa the same evening.

Most citizens go silent for two weeks waiting for a “manager's call”. Do not. The clock under the IRDAI grievance redressal mechanism only starts ticking after a written grievance is on record.

Retail health insurance crossed 70 million covered lives in 2025 in India. Partial settlement is the largest single category of disputes that lands at the Insurance Ombudsman, more than full repudiations. The reason is structural. TPAs operate on tight cost-control margins, hospitals bill in opaque packages, and citizens rarely cross-check a settlement summary against the original bill the same day. By the time the cheque is cashed and the file is closed, citizens assume the cut is “how insurance works”. It is not. It is a negotiation, and you have legal levers if you know where to push.

• IRDAI Master Circular on Health Insurance Business dated 29 May 2024. This is the single most important document for a partly paid claim. It restricts the scope of proportionate deduction, lays down the requirement for written reasons, mandates an updated list of admissible “consumables and non-medical items”, and sets a settlement clock with interest at the bank rate plus 2 per cent for delays.
• IRDAI (Protection of Policyholders' Interests) Operations Regulations 2024. Every claim decision must be communicated in writing with reasons. The insurer has 15 working days to respond to a grievance.
• Insurance Act 1938, §45. The insurer cannot repudiate or reduce a claim on the ground of misstatement or non-disclosure after three years from issuance unless fraud is proved.
• Consumer Protection Act 2019, §2(11). A short-paid claim without reasons is deficiency in service. Citizen can file before the District Commission via edaakhil.
• Insurance Ombudsman Scheme, Redressal of Public Grievances Rules 2017. Free, claim up to Rs 50 lakh, 30 day decision clock, award binding on insurer. See Ombudsman complaint procedure.
• IRDAI list of non-medical items 2020, updated by the 2024 Master Circular. Lists items that are not admissible by default and items that can be admitted if the policy says so. PPE kits, gloves, and masks have been re-classified in the 2024 update.

Use one consolidated email, not five. The exact asks are:

• “Send a line-by-line deduction sheet for this claim.”
• “Cite the exact policy clause behind each deduction.”
• “Give the basis for any 'reasonable and customary' cut, with comparator hospital data.”
• “Confirm whether room rent variation triggered proportionate deduction across other heads, and the policy clause for that.”
• “Confirm the consumables list applied under the IRDAI Master Circular dated 29 May 2024.”
• “Provide the claim manager's name, email, and direct phone number.”
• “Confirm whether any sub-limit, co-payment, or pre-existing condition exclusion was applied.”

Send this from your registered email. Copy the IRDAI grievance cell at [email protected] only if the insurer has already missed a 15 working day deadline.

Dear Sir or Madam,

The settlement received for the above claim is short of the actual hospital bill by Rs [AMOUNT]. I request the following within 15 working days as required by the IRDAI Protection of Policyholders Interests Operations Regulations 2024.

1. A line-by-line deduction sheet for every cut, with the exact policy clause cited next to each.
2. The basis for any "reasonable and customary" reduction, including comparator hospital data.
3. Confirmation whether any room rent variation triggered proportionate deduction across other heads, and the policy clause for that.
4. The consumables and non-medical items list applied to the claim, mapped against the IRDAI Master Circular on Health Insurance Business dated 29 May 2024.
5. Whether the deductions account for any sub-limit, co-payment, or pre-existing condition exclusion.

Policy holder: [Patient Name]
Policy: [POLICY NUMBER]
Claim ID: [CLAIM ID]
Hospitalisation dates: [DATES]
Hospital: [HOSPITAL NAME]
Original bill: Rs [AMOUNT]
Settled: Rs [AMOUNT]
Shortfall: Rs [AMOUNT]

If a reasoned reply does not arrive in 15 working days, I shall file at IRDAI Bima Bharosa and pursue the Insurance Ombudsman remedy.

Regards,
[Patient Name or Proposer Name]

Escalate to IRDAI Bima Bharosa if any of the following is true.

• No deduction sheet has arrived within 15 working days of your written request.
• A deduction sheet exists but has no policy clause against each cut.
• A “reasonable and customary” cut has no comparator data.
• Proportionate deduction has been applied to expenses other than room rent, against the IRDAI 2024 Master Circular.
• Sub-limit or co-payment was not disclosed in the KFD or policy schedule.
• The TPA is refusing to share the version of the consumables list applied.
• The insurer keeps redirecting you to the TPA, and the TPA keeps redirecting you to the insurer.

• Cashing the settlement cheque without writing “received under protest” on the deposit slip or on a follow-up email. This single line keeps the dispute alive.
• Missing the 1 year Ombudsman limitation from the date of the insurer's final reply. Diary it the day you get the reply.
• Filing a fresh grievance at Bima Bharosa without first demanding the deduction sheet in writing. The portal will ask for a copy of the insurer's reply, and a generic “my claim was cut” complaint gets routed back.
• Believing a verbal “the policy clause says so”. Always demand it in writing, with the page and section of the policy schedule.
• Forgetting that proportionate deduction post the 2024 Master Circular is restricted to room rent only. Insurers still apply the old rule on muscle memory. Citizens have to catch it.
• Not asking for the version of the IRDAI consumables list applied to the claim. The 2020 list and the 2024 update differ on PPE and gloves, and many TPAs still run the old list.
• Splitting the challenge across multiple emails. Send one consolidated demand, all six asks in one message, so the 15 working day clock cannot be reset.
• Talking only on phone with the TPA. Voice notes vanish. Always end every phone call with an email recap.
• Letting the cheque date pass while waiting. Interest at 8.5 per cent (bank rate plus 2 per cent under the 2024 Master Circular) accrues to your benefit. The faster you escalate, the faster the meter starts.

• AwaazRTI to draft a grievance to the insurer or to IRDAI in plain Indian English.
• First Appeal Builder if you have to escalate any related RTI to a public health insurer like the New India Assurance Co Ltd or the United India Insurance Co Ltd, which are public authorities under the RTI Act 2005.
• PIO Reply Checker if a public sector insurer gives a vague RTI reply on a settlement decision.
• AI RTI Drafter if you want to file a parallel RTI to a state insurance department or to a regulator's CPIO.

No. Under the IRDAI (Protection of Policyholders' Interests) Operations Regulations 2024 and the IRDAI Master Circular dated 29 May 2024, every deduction must be communicated in writing with a clear reason and the policy clause. A bare “as per policy terms” reply is not a reason. If the insurer does this, file at Bima Bharosa with the email trail attached.

Proportionate deduction is a formula where, if the citizen takes a room category higher than the policy entitles, the insurer reduces other heads in the same ratio. After the IRDAI Master Circular dated 29 May 2024, proportionate deduction can be applied to room rent only, not to associated medical expenses like ICU, surgeon's fee, anaesthesia, OT, consumables, or implants. If the insurer is still applying it across the board, you can challenge.

The 2020 IRDAI list of non-medical items classified gloves, masks, and PPE kits as not admissible by default. The 2024 Master Circular has re-classified some of these as admissible if the policy provides a consumables rider or if the items were essential for the procedure as certified by the treating doctor. Demand the version of the list the TPA applied.

It is a reduction on the ground that the hospital charged more than reasonable for a particular service. It is legal only if the insurer can produce comparator hospital data showing the average charge for the same service in the same city. Without data, the Ombudsman has struck it down repeatedly. Always ask for the data in writing.

Often a large chunk, yes, especially proportionate deduction wrongly applied across heads, consumables wrongly cut, and reasonable and customary reductions without data. Room rent excess, sub-limits clearly disclosed in the KFD, and co-payment usually stay, because the policy clause is clear. A realistic recovery is 40 to 70 per cent of the disputed amount.

No. A formal legal notice is not a precondition. What is needed is a written grievance to the insurer's Grievance Redressal Officer, the insurer's reply or the 15 working day lapse, and a complaint to the Ombudsman in Form P-II with the supporting papers.

Yes. The Insurance Ombudsman accepts complaints within 1 year from the date of the insurer's final reply (or from the date of cause of action if the insurer never replied). Consumer courts under the Consumer Protection Act 2019 have a 2 year limitation. Diary both clocks the day you receive the settlement letter.

The 29 May 2024 Master Circular updates the list of admissible and non-admissible items and requires the insurer to display the list at the policy stage. Items that were earlier rejected by default, such as gloves and PPE kits, can now be admitted if the policy has a consumables rider or if the items are clinically essential and certified by the doctor.

Yes. Under the 2024 Master Circular, interest at the bank rate plus 2 per cent (currently around 8.5 per cent) is payable on amounts delayed beyond the settlement clock. Mention this in the grievance email so the insurer factors it into the recalculation. The Ombudsman routinely awards interest as part of the relief.

For sums up to Rs 50 lakh and where the dispute is about deduction reasons, the Insurance Ombudsman is faster, free, and the award is binding on the insurer. For larger sums, complex factual disputes, or where you also want compensation for mental harassment, the Consumer Commission via edaakhil is the right route. You cannot pursue both at the same time on the same cause of action.
