ICD-10 Code F16.151 – Hallucinogen abuse with hallucinogen-induced psychotic disorder with hallucinations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.151 – Hallucinogen abuse with hallucinogen-induced psychotic disorder with hallucinations
What it is
This code identifies hallucinogen abuse complicated by a psychotic disorder with hallucinations caused by the substance. Use it when the record links hallucinations and psychosis directly to hallucinogen use.
Clinical signs
Typical findings include hallucinations, disturbed thinking, and other psychotic symptoms occurring in the setting of hallucinogen use. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents hallucinogen abuse and specifies a hallucinogen-induced psychotic disorder with hallucinations. It fits cases where the psychosis is attributed to the substance, not a primary psychotic disorder. Check documentation if the substance or diagnosis is unclear.
Do not use for
Do not use this code for hallucinogen use without abuse, or for psychosis not linked to hallucinogen exposure. If the record does not state hallucinations, check documentation.
Coding tip
Assign the code only when the documentation clearly connects the hallucinations to hallucinogen abuse and the induced psychotic disorder.
