ICD-10 Code F02.B0 – Dementia in other diseases classified elsewhere, moderate, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F02.B0 – Dementia in other diseases classified elsewhere, moderate, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety
What it is
This code identifies moderate dementia caused by another underlying disease, with no documented behavioral, psychotic, mood, or anxiety disturbance. Use it when the dementia is secondary and the severity is clearly documented.
Clinical signs
Moderate dementia usually includes noticeable memory loss, impaired reasoning, and difficulty with daily activities. Clinical features vary; refer to documentation for the underlying disease and any confirmed absence of behavioral or psychiatric symptoms.
When to use this code
Use F02.B0 when the provider documents dementia due to another condition and specifies it as moderate. The record should also state that behavioral disturbance, psychosis, mood disturbance, and anxiety are not present. Code the underlying disease separately when required.
Do not use for
Do not use this code if the dementia is mild, severe, or unspecified. Do not use it when behavioral or psychiatric symptoms are documented, or when the chart does not support a secondary dementia diagnosis.
Coding tip
Check documentation for both the causal disease and the exact dementia severity before assigning F02.B0.
