ICD-10 Code F10.159 – Alcohol abuse with alcohol-induced psychotic disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F10.159 – Alcohol abuse with alcohol-induced psychotic disorder, unspecified
What it is
F10.159 identifies alcohol abuse with a psychotic disorder caused by alcohol, when the psychosis type is not otherwise specified. Use it when the record links the mental disturbance to alcohol use and does not name a more specific psychotic presentation.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include hallucinations, delusions, disorganized thinking, or marked behavioral disturbance occurring in the setting of alcohol use or withdrawal.
When to use this code
Use this code when the provider documents alcohol abuse and an alcohol-induced psychotic disorder, but the psychotic disorder is unspecified. It fits cases where the chart supports a direct alcohol-related cause and no more specific psychosis code is documented. Check documentation if alcohol dependence or another substance use disorder is also present.
Do not use for
Do not use it for psychosis with no documented alcohol link, or when the record identifies a different substance as the cause. Avoid it if the note supports alcohol dependence without abuse, unless the provider documents this specific diagnosis.
Coding tip
Code the alcohol-related diagnosis exactly as documented, and query if the record does not clearly connect the psychosis to alcohol.
