ICD-10 Code F10.959 – Alcohol use, unspecified with alcohol-induced psychotic disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F10.959 – Alcohol use, unspecified with alcohol-induced psychotic disorder, unspecified
What it is
F10.959 identifies alcohol use, unspecified when it is associated with an alcohol-induced psychotic disorder, unspecified. Use it when the record confirms psychosis related to alcohol but does not specify the exact psychotic type.
Clinical signs
Clinical features vary; refer to documentation. Typical psychotic features may include hallucinations, delusions, or disorganized thinking, with symptoms linked to alcohol use rather than a primary psychotic disorder.
When to use this code
Use this code when the clinician documents alcohol use and an alcohol-induced psychotic disorder, but the chart does not name a more specific subtype. It also fits when the psychosis is clearly attributed to alcohol and the documentation remains unspecified. Check documentation if another alcohol-related diagnosis is more precise.
Do not use for
Do not use this code for primary psychotic disorders, such as schizophrenia, or when psychosis is not linked to alcohol. Avoid it if the record specifies a different alcohol-induced mental disorder.
Coding tip
Confirm both the alcohol use and the alcohol-induced psychotic disorder are documented before assigning F10.959.
