Short answer · Medically reviewed summary · Last updated: 2026-05-08
Klüver-Bucy syndrome does not have a unique, dedicated code in the ICD-10 or ICD-9 systems; instead, it is typically classified under codes for "other specified disorders of brain" or associated neurological conditions. Clinicians usually report the underlying cause (such as herpes simplex encephalitis or frontotemporal dementia) alongside the specific behavioral symptoms, as there is no single diagnostic code for Klüver-Bucy syndrome itself. What is the clinical classification of Klüver-Bucy syndrome? Because Klüver-Bucy syndrome is a complex behavioral neurological condition resulting from bilateral temporal lobe dysfunction, it is often documented using codes that reflect the primary etiology.

What is the clinical classification of Klüver-Bucy syndrome?
Because Klüver-Bucy syndrome is a complex behavioral neurological condition resulting from bilateral temporal lobe dysfunction, it is often documented using codes that reflect the primary etiology. In ICD-10, for instance, a physician might use G93.89 (Other specified disorders of brain) or codes related to the patient's cognitive or behavioral impairments. Similarly, in ICD-9, practitioners often relied on 348.89 to categorize the manifestation of Klüver-Bucy syndrome.
What are the hallmark symptoms of Klüver-Bucy syndrome?
Klüver-Bucy syndrome is characterized by a distinct constellation of behavioral changes that can be deeply distressing for families. Recognizing these signs is essential for early intervention:
- Hyperphagia: An intense, often indiscriminate compulsion to eat or mouth objects.
- Hypermetamorphosis: An overwhelming urge to explore and touch everything in the visual field.
- Hypersexuality: Increased or inappropriate sexual behavior.
- Visual Agnosia: Difficulty recognizing familiar objects or people.
- Placidity: A significant loss of fear or anger responses, often described as emotional blunting.
How is Klüver-Bucy syndrome diagnosed?
Diagnosis of Klüver-Bucy syndrome is clinical, relying on a comprehensive neurological evaluation, brain imaging (MRI), and neuropsychological testing. Since only 2 people with Klüver-Bucy syndrome have shared their experiences on DiseaseMaps.org, we recognize how rare and isolating this journey can be. Clinical teams must differentiate Klüver-Bucy syndrome from other dementias or post-encephalitic syndromes to ensure the most accurate care plan.
Next steps
- Consult a neurologist or neuropsychiatrist to discuss symptom management and accurate diagnostic coding for your specific case.
- Connect with the community at DiseaseMaps.org to share experiences with others navigating rare neurological conditions.
- Ensure that your medical records clearly document the underlying etiology of your Klüver-Bucy syndrome, as this is vital for insurance and long-term care planning.
