ICD-10 Code F03.B0 – Unspecified Dementia, Moderate, Without Behavioral Disturbance, Psychotic Disturbance, Mood Disturbance, and Anxiety (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F03.B0 – Unspecified dementia, moderate, without behavioral disturbance, psychotic disturbance, mood disturbance, and anxiety
What it is
This code identifies dementia of moderate severity when the type is not specified and no behavioral, psychotic, mood, or anxiety disturbance is documented. Use it when the record supports dementia but does not name a more specific form.
Clinical signs
Clinical features vary; refer to documentation. Moderate dementia typically includes clear impairment in memory, reasoning, and daily functioning, but the chart should not describe associated behavioral or psychiatric disturbance for this code.
When to use this code
Use F03.B0 when the provider documents unspecified dementia and states it is moderate. It also fits when the note specifically says there is no behavioral disturbance, psychotic disturbance, mood disturbance, or anxiety. If the dementia type is identified, check for a more specific code.
Do not use for
Do not use this code if the dementia subtype is documented, such as Alzheimer’s disease or vascular dementia. Also avoid it when behavioral, psychotic, mood, or anxiety disturbance is present or documented elsewhere.
Coding tip
Confirm both severity and the absence of behavioral or psychiatric disturbance before assigning F03.B0.
