Health Insurance Claim Denied for Alzheimer's and NPH Based on Symptom History, Not Diagnosis

A family ported a senior citizen's health insurance policy to a new insurer, disclosing all known medical conditions at the time of porting. The only declared condition was a gastric ailment. No neurological conditions had been identified, and the policyholder had made no prior claims related to brain or cognitive health under the previous insurer.

Months after the policy came into force, the family noticed changes in the senior citizen's behaviour and sought medical attention. A specialist evaluation led to a diagnosis of Normal Pressure Hydrocephalus (NPH). Later, following a detailed assessment at a leading tertiary care facility, Alzheimer's disease was formally diagnosed for the first time. Both diagnoses were made after the new policy had been in effect.

The family subsequently filed two hospitalisation claims, each of modest value. Both were rejected. Shortly after, the insurer terminated the policy entirely.

The stated basis for rejection was language found in hospital discharge summaries. The documents referred to "abnormal behaviour since 3 years" and, in a later record, "6 to 7 years." The insurer treated these retrospective symptom descriptions as proof that the conditions existed before porting and were therefore pre-existing diseases that had not been disclosed.

The family pushed back, pointing out a critical distinction: a history of symptoms is not the same as a prior diagnosis. No medical record, specialist letter, or investigation report from before the porting date stated that either NPH or Alzheimer's disease had been diagnosed. Discharge summaries routinely capture a patient's reported symptom timeline, as recalled by family members, and this narrative cannot be equated with a formal clinical diagnosis on a specific date.

The family also raised a practical question that cuts to the heart of the matter. If these conditions had genuinely been present and diagnosed before the policy was ported, there would have been claims under the previous insurer. There were none. The absence of any prior claim history supports the position that no actionable diagnosis existed before the porting date.

Despite these arguments, the family was asked repeatedly to resubmit the same documents and explanations over several months, adding to the burden of caring for a seriously ill senior citizen.

This case illustrates a pattern that affects many families. Insurers sometimes use symptom-timeline language in discharge notes as a shortcut to invoke pre-existing disease exclusions, without establishing that a formal diagnosis actually preceded the policy. The distinction between "symptoms reported for several years" and "diagnosed before the policy commenced" is medically and legally significant, and conflating the two can result in unjust claim denials.

What went wrong

• The insurer treated retrospective symptom descriptions in discharge summaries as proof of a pre-existing diagnosis, without establishing when a formal diagnosis was actually made.
• No distinction was drawn between a patient's reported symptom history and a clinician's dated diagnosis, which are medically and legally separate concepts.
• Both hospitalisation claims were rejected despite the conditions being formally diagnosed only after the policy came into force.
• The policy was terminated entirely on the basis of alleged non-disclosure, a serious action applied without clear evidence that a diagnosis existed before porting.
• The family was subjected to months of repeated document submissions without a substantive re-evaluation, adding burden during an already difficult caregiving period.
• The absence of any prior claims under the previous insurer, which would have existed had the conditions been diagnosed earlier, was apparently not given adequate weight.

What evidence mattered

• Specialist reports or clinical letters carrying an explicit first-diagnosis date for both NPH and Alzheimer's disease, confirming diagnosis occurred after the porting date.
• Imaging and investigation reports (such as MRI or CSF studies) with dated results, demonstrating when diagnostic criteria were first met.
• The original porting proposal form showing declared conditions at the time of porting, to confirm no neurological condition was known or diagnosed then.
• A letter or certificate from the previous insurer confirming no claims were made for neurological or cognitive conditions during the prior policy period.
• A written medical opinion from a neurologist clarifying the distinction between retrospective symptom history in discharge summaries and a formal clinical diagnosis date.
• All insurer rejection letters in writing, to identify the precise grounds cited and to build a documented record for escalation.

The escalation route that applies

1. 1.Submit a formal written grievance to the insurer's internal grievance redressal officer, referencing the specific rejection grounds and attaching the dated specialist diagnosis reports.
2. 2.If the insurer's grievance response is unsatisfactory or not received within the applicable period, file a complaint with the applicable insurance ombudsman having jurisdiction over the policyholder's location.
3. 3.Simultaneously or subsequently, lodge a complaint with the applicable regulator citing the denial pattern and the policy termination, requesting a review of whether the termination was justified.
4. 4.If the ombudsman process does not resolve the matter, consider approaching the applicable consumer disputes forum with the full documented record of rejections, submissions, and medical evidence.

Solvh's take

This case reflects a well-documented gap between how clinicians document history and how insurers interpret that documentation. When a patient presents with a neurological condition, treating physicians routinely ask families how long they have noticed changes, and that recollected timeline enters the discharge summary as part of the presenting history. Insurers can, and sometimes do, use this narrative language to argue that the condition pre-dated the policy.

The flaw in that reasoning is that subjective symptom timelines reported by family members are not equivalent to a formal clinical diagnosis. Alzheimer's disease and NPH are both conditions that typically have a long, ambiguous prodromal phase. Observable behavioural changes may appear years before any physician applies a diagnostic label. A retrospective symptom history in a discharge note does not establish when a diagnosis was made, only when the family noticed something was wrong.

A fair assessment should focus on the date of first formal diagnosis, supported by specialist reports, imaging results, and clinical letters, rather than on lay-reported symptom duration embedded in a discharge summary. The absence of any prior claim under the previous insurer is a strong corroborating fact: if the condition had been diagnosed and treated before porting, there would almost certainly be a record of medical expenditure.

The policy termination following two modest claims raises additional concerns. Terminating a policy on the basis of an alleged non-disclosure, rather than simply adjusting the terms, is a significant step that requires clear evidence of deliberate concealment of a known diagnosis. Where no pre-porting diagnosis can be demonstrated, this approach risks being seen as disproportionate.

For families in this situation, the priority is assembling a clear chronological medical record: the porting proposal form, the previous insurer's claims history (or confirmation of no claims), and specialist reports carrying explicit first-diagnosis dates. Challenging the insurer's characterisation of discharge summary language, in writing and with supporting medical opinion if needed, is the logical next step before escalating through the standard grievance process and, if necessary, to the applicable regulator or insurance ombudsman.
