7 Reasons Health Insurance Claims Get Rejected in India (Avoid These Costly Mistakes)

Ramesh did everything right. He paid his health insurance premium every year for eight years straight. Then his father had a heart attack — 17 days in the ICU, and a bill of ₹8.4 lakh.

His insurer rejected the entire claim.

Stories like this aren’t rare. According to IRDAI’s Annual Report for FY 2024–25, Indian insurers rejected or repudiated health insurance claims worth close to ₹30,000 crore — up 15% from the year before. That’s real money, denied to real families, at the worst possible moment.

The good news: most rejections come down to a handful of avoidable mistakes. In this post (and the video below), we break down the 7 most common reasons health insurance claims get rejected in India, and exactly what to do about each one.

The Scale of the Problem

A few numbers worth sitting with, all from IRDAI and the Insurance Ombudsman:

• 11–15% of all health insurance claims in India are rejected industry-wide
• 19.1% rise in rejection value reported in FY24
• ~40% of disputed rejections are overturned when policyholders appeal to the Insurance Ombudsman

That last number matters. A rejection isn’t automatically the final word — but it’s far easier to avoid the rejection in the first place than to fight it after the fact.

Know Your Rights First

Before we get into the 7 reasons, one thing every policyholder should know: under IRDAI regulations, your insurer must give you a specific, written reason for any claim rejection, tied to the exact clause in your policy. They can’t simply say “not covered” without pointing to the relevant terms, and no claim can be repudiated without internal committee approval at the insurer.

Keep that in mind — it matters if you ever need to push back.

The 7 Reasons Claims Get Rejected

1. Missing or Incorrect Patient Information

It sounds too simple to matter, but it causes thousands of rejections every year. A policy number off by one digit. A name that doesn’t exactly match your ID. A mismatched date of birth. To an insurer’s system, that’s not a small typo — it’s a claim that doesn’t match a policy.

Do this: Cross-check your policy number, name spelling, and date of birth against your Aadhaar or PAN today — not during an emergency.

2. Filing After the Deadline

Every policy has strict timelines. Cashless treatment requires intimation before a planned admission, or within 24 hours for an emergency. Reimbursement claims typically must be filed within 15–30 days of discharge. Miss that window, and insurers can reject the claim on procedure alone — even if the treatment itself was completely valid.

Do this: The moment of admission, send one message or email to your insurer or TPA immediately. Don’t wait until after discharge.

3. Claiming for a Pre-Existing Condition During the Waiting Period

If you had diabetes, hypertension, or any diagnosed condition before buying your policy, most insurers apply a waiting period — commonly two to four years — before they’ll cover treatment related to it. File before that window closes, and it’s an automatic rejection.

Do this: Read your policy schedule tonight and note the exact waiting period for any condition you disclosed. Mark the date in your calendar.

4. Submitting a Claim Without Pre-Authorization

This is the one that catches even careful, well-informed people off guard. For planned, cashless hospitalization, most insurers require approval before treatment begins, not after. Walk in without it, and you may be forced to pay out of pocket first, then fight for reimbursement — or be denied altogether for skipping the process.

Do this: Before any planned procedure, call your insurer’s helpline or TPA yourself and get written pre-authorization. Don’t rely on the hospital’s insurance desk to handle it for you.

5. Falling Under a Policy Exclusion

Cosmetic procedures, certain dental work, childbirth on a basic plan, treatments from unrecognized systems of medicine, self-inflicted injury — every policy has a list of what it will never cover, no matter when you file.

Do this: Open the exclusions section of your policy document — usually just two or three pages — and actually read it once. Most people never do.

6. Incomplete Medical Bills, Reports, or Missing Signatures

A discharge summary without the treating doctor’s signature. A pharmacy bill without a prescription attached. A lab report missing a page. Insurers don’t guess — if a document is incomplete, the claim gets sent back or rejected outright.

Do this: Before you leave the hospital, verify your complete document folder — original bills, signed discharge summary, every investigation report, every prescription.

7. Seeking Treatment at a Non-Network Hospital

Cashless treatment only works at hospitals your insurer has a direct tie-up with. Treatment outside that network — even in an emergency — may still be reimbursed, but often at a lower approved rate, with more paperwork and more chances of partial rejection.

Do this: Save your insurer’s network hospital list for your city on your phone right now, so in an emergency you’re choosing correctly in seconds.

A Rejection Isn’t the Final Answer

Here’s the part worth remembering: most of these seven reasons are avoidable gaps, not the insurer being unfair. And if your claim does get rejected, you have the right to appeal — first to your insurer’s Grievance Redressal Officer (GRO), then to Bima Bharosa (IRDAI’s grievance portal), and finally to the Insurance Ombudsman. As noted above, roughly 4 in 10 disputed rejections get overturned at that stage.

Frequently Asked Questions

How long do I have to file a health insurance claim in India? Reimbursement claims typically must be filed within 15–30 days of discharge, though the exact window varies by insurer — check your policy document for the specific number. Cashless claims require intimation before a planned admission, or within 24 hours for an emergency.

Can I still get reimbursed if I go to a non-network hospital? Often yes, but only through the reimbursement route (not cashless), usually at a lower approved rate and with more documentation required.

What can I do if my health insurance claim is rejected? First, request the specific written reason from your insurer — they’re required to provide one. If you believe the rejection is wrong, escalate to your insurer’s Grievance Redressal Officer, then Bima Bharosa, and finally the Insurance Ombudsman if needed.

Do pre-existing conditions ever become covered? Yes — after the waiting period specified in your policy (commonly 2–4 years) has passed. After 8 continuous years of coverage, insurers generally cannot reject claims for non-disclosure except in proven fraud cases.
