Health Claim Rejected for Pre-Existing Disease After Waiting Period Was Confirmed Complete

A family purchased a health insurance policy with a standard 24-month waiting period for pre-existing diseases. They paid every premium on time and, on entering the third year of the policy, had every reason to believe the waiting period had lapsed. When a relative covered under the policy required urgent surgery, the family did what any responsible policyholder would do: they contacted the insurer before proceeding. Both the agent who had sold them the policy and the insurer's customer care helpline confirmed in clear terms that the waiting period was over and that the upcoming surgery would be eligible for a claim.

Acting on that confirmation, the family arranged for the procedure at a network hospital. The insurer then requested a specific letter from the treating doctor, on official letterhead, confirming the diagnosis and the date on which the patient had first presented with the condition. The family obtained this letter and submitted it along with the full set of claim documents.

The claim was rejected. The stated reason was that the surgical condition qualified as a pre-existing disease and therefore fell within the exclusion period. No additional medical investigation was cited. The insurer offered no explanation for why the same condition that its own representatives had declared eligible for cover was suddenly being treated as excluded.

The consequences were immediate and serious. The patient's surgery was postponed. The family, which had structured its finances around the assumption that the insurance would respond, was now looking at a bill running into several lakhs of rupees with no alternative funding in place.

The policyholder responded by formally disputing the rejection in writing. This written representation to the insurer is an essential step: under the applicable regulatory framework, a complainant must first make a written representation to the insurer and either receive an unsatisfactory reply or wait one month without a response before approaching the Insurance Ombudsman. Filing with the Insurance Ombudsman carries no fee or charge. Separately, a complaint can also be registered through IRDAI's Bima Bharosa grievance portal, though that registration does not by itself satisfy the precondition for the Ombudsman route.

The case illustrates a recurring and serious pattern: a policyholder fulfils every obligation, receives oral confirmation of eligibility, produces the documents specifically requested by the insurer, and is still denied cover. The question left hanging is whether the insurer conducted a genuine medical review at any point before issuing the rejection, or whether the pre-existing disease label was applied without proper clinical basis.

What went wrong

• The insurer's agent and customer care helpline verbally confirmed claim eligibility, but that confirmation was not honoured at the claims processing stage.
• The insurer requested a specific doctor's letter on diagnosis and first-visit date, received it, and still rejected the claim on pre-existing disease grounds without citing any new medical evidence.
• No clinical or investigative basis was provided for concluding that the condition was pre-existing, making the rejection appear arbitrary.
• The 24-month waiting period had elapsed before the claim was submitted, yet the exclusion was applied as though it had not.
• The patient's surgery was delayed as a direct consequence of the claim rejection, compounding the medical harm.
• The family was left without an alternative financial arrangement because they had reasonably relied on the insurer's own eligibility confirmation.

What evidence mattered

• Written or recorded confirmation from the insurer's agent or customer care that the waiting period had ended and the procedure was eligible for cover.
• The specific doctor's letter requested by the insurer, showing the diagnosis and the date of first presentation, to establish whether the condition arose before or after policy inception.
• The insurer's written rejection letter, including the exact clause and medical basis cited for invoking the pre-existing disease exclusion.
• The policy document and schedule showing the policy start date, the 24-month waiting period clause, and the definition of pre-existing disease used.
• Premium payment receipts confirming continuous and timely payment throughout the policy term.
• Any internal claim assessment notes or investigation reports obtained through a formal document request, to check whether a clinical review was actually conducted.

The escalation route that applies

1. 1.Send a formal written representation to the insurer's grievance officer, clearly stating the facts, attaching all supporting documents, and specifying the relief sought. Keep proof of dispatch and delivery.
2. 2.If the insurer rejects the representation, sends an unsatisfactory reply, or does not respond within one month, the complainant becomes eligible to file a complaint with the Insurance Ombudsman having jurisdiction over the insurer's branch. No fee or charge is payable to lodge a complaint with the Insurance Ombudsman.
3. 3.In parallel, register a grievance on the IRDAI Bima Bharosa portal. Note that this is a separate regulatory channel and does not by itself satisfy the precondition for the Ombudsman route, which requires the written representation to the insurer first.
4. 4.If the Ombudsman route does not resolve the matter, consider filing a complaint before the appropriate consumer forum. Be aware that once a matter is pending before a court, consumer forum, or arbitrator, the Insurance Ombudsman cannot entertain the same complaint simultaneously.

Solvh's take

This case fits a well-documented pattern in Indian health insurance: the pre-existing disease exclusion is invoked not on a fresh clinical finding but as a convenient label applied after the policyholder has already incurred the cost and inconvenience of gathering documents. Several features make this particular instance especially troubling.

First, the insurer's own representatives confirmed eligibility before the claim was lodged. That confirmation, if it can be evidenced, significantly weakens the insurer's position because it suggests either that the insurer's own staff do not understand its policy terms, or that the terms are being selectively interpreted at the claims stage.

Second, the insurer requested a specific doctor's letter confirming the diagnosis and the date of first presentation. This request implies the insurer was already alive to the pre-existing disease question. Requesting that document and then rejecting the claim on the same ground, without citing any additional medical evidence, points to a process failure: either the document was not properly reviewed, or the grounds for rejection were decided before the document arrived.

Third, the 24-month waiting period had elapsed. If the condition arose or was first diagnosed after the policy was purchased, the pre-existing disease exclusion has no application at all. If the insurer is asserting that the condition pre-dates the policy, it bears the burden of producing the medical evidence that supports that finding.

Systemically, this case reveals the danger of relying on verbal confirmations from agents or helplines without obtaining written acknowledgment. It also highlights the gap between what policy documents say and how claims teams interpret them at the point of settlement. Families in genuine medical emergencies are least equipped to challenge these decisions quickly, which can make delayed surgery a de facto punishment for disputing a rejection.
