Diagnostic centre bills your insurer will not accept: how to fix it

Who this guide is for

This guide is for you if a health insurer or its TPA will not accept or reimburse your diagnostic test bills. Common situations:

• Your hospitalisation claim was paid, but the pathology, scan or radiology bills inside it were disallowed or deducted.
• You paid for tests at a diagnostic centre on a doctor's advice and the insurer calls them standalone or OPD investigations and refuses them.
• The bills were rejected as missing documents — no prescription, no report, or not the original bill — even though you have them.
• The diagnostic centre was outside the insurer's or TPA's network, and the bills were declined or heavily cut on that ground.
• You are covered by a government scheme (CGHS, ECHS or a state medical-reimbursement scheme) and your diagnostic reimbursement was objected to or partly disallowed.

What you can do this weekend

Friday evening

Pin down the exact written reason for the rejection. Open the insurer or TPA email, SMS, claim portal status, or the settlement and deduction letter, and note the precise ground stated for each disallowed test. If you only have a phone call or a vague line, write to the insurer and TPA asking for the rejection reason in writing with the policy clause relied on.

• Save screenshots of the claim status and every message, with dates.
• Note your policy number, claim or intimation number, and the TPA reference.

Saturday

Build the matched file. Lay the doctor's prescription or advice note next to every diagnostic bill and report, so each test clearly links to the diagnosis and the treatment or admission.

• Put each test in a simple row: test name, date, bill, report, and the prescription line that ordered it.
• Pull your policy wording and read what it says about diagnostic tests, OPD cover, pre- and post-hospitalisation, and network labs.
• Flag the gap: for example, a missing prescription you can still get from the treating doctor, or a report you can re-collect from the lab.

Sunday

Draft your written representation to the insurer's grievance or claims officer using the template below. Keep it calm and factual, attach the matched file, and ask for reconsideration of the disallowed diagnostic bills.

• State the rejection reason you were given and answer it point by point with your evidence.
• Keep the originals safe and send clear copies; never give away your only originals.
• Plan Monday: send the representation, ask for an acknowledgement and reference, and note when you can escalate to Bima Bharosa.

Documents and evidence checklist

Step-by-step action plan

1. Get the exact rejection reason in writing. Ask the insurer and the TPA, in writing, for the precise ground on which each diagnostic bill was disallowed, and the policy clause relied on. A vague phone refusal is not enough; you need the written reason to answer it properly.
2. Match every test to a prescription and report. Lay each diagnostic bill beside the doctor's prescription that ordered it and the matching test report. This shows the tests were medically advised and actually done, which answers the usual 'standalone' or 'unsupported' rejection.
3. Read your policy on diagnostics and OPD. Check what your policy actually covers: diagnostic tests, OPD investigations, pre- and post-hospitalisation expenses, network-lab conditions and any sub-limits. Confirm whether the rejection reason genuinely fits your policy or is a mistake.
4. Send a written representation to the insurer. Write to the insurer's claims or grievance officer. State the rejection reason, answer it point by point with your matched evidence, attach clear copies, and ask in writing for reconsideration and a written reply with a reference number.
5. Escalate to the insurer's grievance redressal officer. If the claims team still refuses, address the insurer's Grievance Redressal Officer named in your policy and on the insurer's website. Keep it to the same facts and evidence, and ask for a clear, written final decision.
6. Register the complaint on IRDAI Bima Bharosa. If the insurer does not resolve it satisfactorily, register your grievance on IRDAI's Bima Bharosa portal. You get a token to track it, and the insurer's response is mirrored there. Keep that token with your file.
7. Approach the Insurance Ombudsman. If Bima Bharosa and the insurer do not resolve it within the timeline shown on the portal, take it to the Insurance Ombudsman through cioins.co.in. File within the time limit set by the Insurance Ombudsman Rules; the Ombudsman is free for policyholders.
8. Use RTI only where a public body holds the record. If your insurer is a public-sector (government) insurer, or a government scheme like CGHS or ECHS objected to your diagnostic reimbursement, file an RTI for your claim file, the assessment notes and the exact ground of disallowance. This builds evidence; it does not itself pay you.
9. File a consumer complaint if still unpaid. If a genuine, covered diagnostic bill stays rejected, file on the e-Daakhil portal before the District or State Consumer Commission for deficiency of service. Attach the rejection letter, matched bills and reports, policy wording and your full correspondence trail.

To: The Claims / Grievance Redressal Officer
[Insurance company name] (through TPA [TPA name], if applicable)

Subject: Written representation for reconsideration of disallowed diagnostic test bills under claim no. [claim/intimation number], policy no. [policy number]

Dear Sir / Madam,

I am the policyholder/insured under the above health policy. In connection with my claim no. [claim/intimation number], the following diagnostic bills were rejected/deducted, for which I request reconsideration.

Reason stated by you for the rejection: [paste the exact written reason / policy clause you were given].

The disallowed diagnostic items are:
1) [test name], dated [date], bill no. [number], amount [amount] — ordered by Dr [name] on prescription dated [date]; report attached.
2) [test name], dated [date], bill no. [number], amount [amount] — ordered by Dr [name] on prescription dated [date]; report attached.
3) [test name], dated [date], bill no. [number], amount [amount] — ordered by Dr [name] on prescription dated [date]; report attached.

Why these are payable under my policy:
- Each test was advised in writing by the treating doctor for my diagnosis/treatment and was actually done, as the attached prescriptions and reports show.
- [If hospitalised:] These tests fall within my hospitalisation / pre- and post-hospitalisation cover, as the discharge summary dated [date] confirms.
- [If the reason was 'missing document':] I now enclose the [prescription / report / original bill] that was said to be missing.
- [If the reason was 'non-network lab':] My policy [does not restrict reimbursement to network labs / allows reimbursement of reasonable diagnostic charges]; please point me to the exact clause if you disagree.

I therefore request you to (a) reconsider and reimburse the disallowed diagnostic bills, and (b) send me a written decision with the specific policy clause if any amount is still declined. Kindly acknowledge this representation with a reference number.

If I do not receive a satisfactory written resolution, I will be constrained to escalate to your Grievance Redressal Officer, IRDAI's Bima Bharosa portal, the Insurance Ombudsman, and, if necessary, the Consumer Disputes Redressal Commission.

I am attaching the rejection/deduction letter, the diagnostic bills and reports, the doctor's prescriptions, the discharge summary (if any), and my policy schedule.

Thank you.

When RTI can help

RTI is genuinely useful here only when a public authority holds your record, and even then as an evidence and pressure tool, not as a way to force a payout. The real openings are:

• A public-sector (government) general insurer. The government-owned general insurers are public authorities under the RTI Act. If your health policy is with one of them, you can file an RTI with its Public Information Officer for your own claim file, the surveyor's or assessor's notes, the internal reason your diagnostic bills were disallowed, and the policy clause relied on.
• A government health-reimbursement scheme. If you claim under CGHS, ECHS, a railway or state-government medical-reimbursement scheme and your diagnostic reimbursement was objected to or cut, RTI goes to that scheme authority — ask for the approved diagnostic rate list, your claim or reimbursement file, and the exact ground of disallowance.
• A government diagnostic lab. If the tests were done at a government or public-hospital lab, an RTI for its official rate list helps you prove the charges were genuine and standard, which supports your claim elsewhere.

These answers carry weight at the Insurance Ombudsman or a consumer commission, because they show the official position or the approved rate next to what you were actually billed and refused.

When RTI will not help

For the most common situation — a private health insurer, a private TPA, or a private diagnostic centre — RTI does not apply, because none of them is a public authority under the RTI Act. You cannot RTI a private insurer for its claim file, and RTI will never compel anyone to pay your bill or reverse a rejection.

For a private health-insurance dispute, use the insurance grievance chain instead: a written representation to the insurer's claims and Grievance Redressal Officer, then IRDAI's Bima Bharosa portal (bimabharosa.irdai.gov.in), and then the Insurance Ombudsman (cioins.co.in), which is free for policyholders. Because health cover is a paid service, you can also take a clear case of unfair rejection to the Consumer Disputes Redressal Commission via e-Daakhil (edaakhil.nic.in), or log it with the National Consumer Helpline (consumerhelpline.gov.in). Note that CPGRAMS (pgportal.gov.in) is for government departments and public-sector bodies — it fits a public-sector insurer or a government scheme, not a purely private insurer.

Common mistakes to avoid

• Accepting a verbal or one-line rejection and never getting the exact written reason and policy clause — you cannot answer a ground you have not been told.
• Sending your only original bills and reports to the insurer; keep the originals and send clear, certified copies.
• Submitting bills without the matching doctor's prescription, which lets the insurer reject genuine tests as standalone investigations.
• Filing an RTI against a private insurer or a private diagnostic centre — they are outside the RTI Act; use the insurance grievance chain instead.
• Letting the escalation clock run out — the Insurance Ombudsman has time limits, so diarise dates and escalate in writing rather than waiting on promises.
• Treating a network-lab deduction and a total rejection the same way; read your policy, because the right argument differs for each.

FAQs

Why do insurers reject diagnostic test bills?

Usually for a few reasons: the tests are treated as standalone or OPD investigations not linked to covered treatment, the prescription or report was missing, only certified copies and not originals were sent, the lab was outside the network, the claim was filed late, or the policy has a waiting period or sub-limit. Get the exact written reason first; the right answer depends on which ground was used.

What is the first thing I should do?

Get the exact reason for rejection in writing from the insurer or TPA, with the policy clause relied on. A phone call is not enough. Then match every disallowed test to the doctor's prescription that ordered it and to its report, so each bill clearly links to your diagnosis and treatment. That matched file is the basis for your representation.

Can RTI force my insurer to pay the diagnostic bills?

No. RTI never compels a payout or reverses a rejection. It only gives you information, and only from a public authority. For a private insurer, RTI does not even apply. To actually get paid, use the insurer's grievance officer, IRDAI's Bima Bharosa portal, the Insurance Ombudsman, and, if needed, a consumer commission via e-Daakhil.

When does RTI actually help with rejected diagnostic bills?

RTI helps when a public body holds the record: a public-sector (government) general insurer, for your claim file and the internal reason for disallowance; a government scheme such as CGHS or ECHS, for the approved diagnostic rates and your reimbursement file; or a government diagnostic lab, for its official rate list. It builds evidence you can use at the Ombudsman or a consumer forum.

The insurer says the tests were OPD or standalone. What now?

Show the link to treatment. Attach the doctor's prescription that ordered each test and, where relevant, the discharge summary connecting the tests to a hospitalisation or to pre- and post-hospitalisation cover. If your policy genuinely excludes pure OPD diagnostics, point that out honestly, but make sure the insurer has not wrongly labelled hospital-linked tests as OPD.

My diagnostic centre was not in the network. Can I still claim?

It depends on your policy. Many reimbursement policies pay reasonable diagnostic charges regardless of the lab, while some cashless or network-linked plans restrict it. Read your policy wording, and if it does not limit reimbursement to network labs, ask the insurer to point to the exact clause they are relying on before they deduct or reject.

How do I escalate if the insurer still refuses?

Escalate in writing to the insurer's Grievance Redressal Officer, then register on IRDAI's Bima Bharosa portal and keep the token to track it. If it is still unresolved, approach the Insurance Ombudsman through cioins.co.in within the time limit in the Ombudsman Rules. You can also file before a consumer commission on e-Daakhil for deficiency of service.

Which documents do I need to keep?

Keep the written rejection or deduction letter, the original diagnostic bills, the report for each test, the doctor's prescriptions, the discharge summary if you were admitted, your policy schedule and wording, the claim form and TPA correspondence, and a short dated timeline. These are needed at every escalation level and before the Ombudsman or a consumer commission.

Clear next steps

• Write to the insurer and TPA asking for the exact rejection reason and policy clause in writing, and save the claim-status screenshots.
• Lay each disallowed test bill beside the doctor's prescription and its report, and note any gap you can still fill.
• Read your policy on diagnostics, OPD, pre- and post-hospitalisation, and network labs.
• Send the insurer a written representation asking for reconsideration, and request an acknowledgement with a reference number.
• If unresolved, plan your Bima Bharosa complaint, and use RTI only if a public-sector insurer or a government scheme is involved.
