ICD-10 Code F03.B2 – Unspecified dementia, moderate, with psychotic disturbance (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F03.B2 – Unspecified dementia, moderate, with psychotic disturbance
What it is
This code identifies dementia of unspecified cause with moderate severity and documented psychotic disturbance. Use it when the record supports dementia but does not specify the underlying type.
Clinical signs
Moderate dementia commonly involves clear memory loss, impaired judgment, and reduced independence in daily activities. Psychotic disturbance may include hallucinations, delusions, or other documented psychotic features; clinical features vary, refer to documentation.
When to use this code
Use F03.B2 when the clinician documents unspecified dementia, moderate, and also notes psychotic disturbance. This is appropriate when the chart lacks a more specific dementia diagnosis, such as Alzheimer disease or vascular dementia. Check documentation if severity or psychotic features are unclear.
Do not use for
Do not use this code if the dementia type is specified elsewhere in the record, or if psychotic symptoms are present without documented dementia. Do not assign it for mild, severe, or unspecified severity without the documented moderate level.
Coding tip
Verify both elements: moderate dementia and psychotic disturbance must be explicitly documented before you assign F03.B2.
