ICD-10 Code G31.01 – Pick’s Disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G31.01 – Pick’s disease
What it is
Pick’s disease is a rare, progressive neurodegenerative disorder that causes frontotemporal dementia. It refers to a specific disease process affecting the frontal and temporal lobes of the brain.
Clinical signs
Typical findings include personality change, disinhibition, apathy, language impairment, and progressive cognitive decline. Clinical features vary; refer to documentation.
When to use this code
Use G31.01 when the provider documents Pick’s disease or confirms this specific form of frontotemporal dementia. Apply it for encounters focused on established diagnosis, evaluation, or ongoing management of the condition. Check documentation if the chart only says dementia or behavioral change.
Do not use for
Do not use this code for nonspecific dementia, Alzheimer disease, or other frontotemporal disorders without documentation of Pick’s disease. Check documentation when the diagnosis is uncertain.
Coding tip
Code G31.01 only when the record clearly names Pick’s disease; otherwise, query for the exact dementia type.
