ICD-10 Code F16.15 – Hallucinogen abuse with hallucinogen-induced psychotic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.15 – Hallucinogen abuse with hallucinogen-induced psychotic disorder
What it is
This code identifies hallucinogen abuse complicated by a psychotic disorder caused by hallucinogen use. It applies when the substance use and the psychotic symptoms are linked in the record.
Clinical signs
Documented features may include hallucinations, delusions, paranoia, disorganized thinking, or marked behavioral disturbance. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents hallucinogen abuse with a hallucinogen-induced psychotic disorder. The record should support both the substance-related disorder and the psychotic condition.
Choose it for cases where the psychosis is attributed to hallucinogen use rather than a primary psychiatric disorder. Check documentation if the cause, timing, or substance relationship is unclear.
Do not use for
Do not use this code for hallucinogen use without abuse or without psychotic disorder. Do not assign it when the psychosis is documented as unrelated to the substance.
Coding tip
Confirm that the provider explicitly links the psychotic disorder to hallucinogen abuse before assigning F16.15.
