ICD-10 Code F15.959 – Other Stimulant Use, Unspecified with Stimulant-Induced Psychotic Disorder, Unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.959 – Other stimulant use, unspecified with stimulant-induced psychotic disorder, unspecified
What it is
This code identifies stimulant use with a stimulant-induced psychotic disorder when the stimulant type is not more specifically identified. Use it when psychosis is attributed to stimulant use and the documentation does not specify the stimulant or the psychotic subtype.
Clinical signs
Typical features include hallucinations, delusions, paranoia, or disorganized thinking linked to stimulant use. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents both stimulant use and a stimulant-induced psychotic disorder, but the stimulant is otherwise unspecified. It also fits cases where the provider links psychosis to stimulant use without naming a more specific stimulant-related diagnosis. Check documentation if substance details are unclear.
Do not use for
Do not use this code for psychosis unrelated to stimulant use, or when another substance is documented as the cause. If the chart does not support a stimulant-induced psychotic disorder, check documentation.
Coding tip
Code only when the provider clearly connects the psychotic disorder to stimulant use and the stimulant remains unspecified.
