ICD-10 Code F19.15 – Other psychoactive substance abuse with psychoactive substance-induced psychotic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.15 – Other psychoactive substance abuse with psychoactive substance-induced psychotic disorder
What it is
F19.15 identifies abuse of another psychoactive substance when the patient also has a psychotic disorder caused by that substance. Use it when the record links the psychosis directly to the substance use.
Clinical signs
Clinical features vary; refer to documentation. Typical psychotic features may include hallucinations, delusions, disorganized thinking, or markedly impaired reality testing occurring in the setting of substance use.
When to use this code
Use this code when the provider documents both psychoactive substance abuse and a substance-induced psychotic disorder, and the substance is not named in a more specific ICD-10 category. Confirm that the psychosis is attributed to the substance rather than a primary psychiatric disorder. Check documentation if the substance type or relationship is unclear.
Do not use for
Do not use this code for psychosis unrelated to substance use, or for substance use without documented psychotic disorder. If the record identifies a specific drug category with a more precise code, use that instead.
Coding tip
Code only when the provider clearly links the psychotic disorder to the abused psychoactive substance.
