ICD-10 Code F15.950 – Other stimulant use, unspecified with stimulant-induced psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.950 – Other stimulant use, unspecified with stimulant-induced psychotic disorder with delusions
What it is
This code identifies stimulant use, unspecified, when the patient has a stimulant-induced psychotic disorder marked by delusions. It reflects psychosis caused by stimulant use rather than a primary psychotic disorder.
Clinical signs
Look for delusional beliefs occurring in the setting of stimulant use, with symptoms not better explained by another mental disorder. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly links stimulant use to psychotic symptoms and specifies delusions. It fits cases where the stimulant is not further identified, but the psychotic disorder is documented. If the provider does not state delusions or the stimulant relationship, check documentation.
Do not use for
Do not use this code for primary psychotic disorders, substance use without psychosis, or stimulant intoxication alone. Do not assign it if the chart does not support stimulant-induced delusions.
Coding tip
Confirm both the stimulant-related cause and the delusional psychosis in the provider note before assigning F15.950.
