ICD-10 Code F16.150 – Hallucinogen abuse with hallucinogen-induced psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.150 – Hallucinogen abuse with hallucinogen-induced psychotic disorder with delusions
What it is
This code identifies hallucinogen abuse accompanied by a psychotic disorder marked by delusions. Use it when the record links hallucinogen use to persistent false beliefs that are not better explained by another condition.
Clinical signs
Clinical features may include delusions, impaired reality testing, and behavior consistent with intoxication or substance-related psychosis. 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 delusions. It is appropriate when the psychotic symptoms are attributed to hallucinogen use in the medical record.
Choose it for encounters where the diagnosis is clearly stated, even if the exact substance is not named in the note. Check documentation if the record does not clearly connect the psychosis and the hallucinogen use.
Do not use for
Do not use this code for hallucinogen use without abuse, or for psychosis not linked to hallucinogen use. Do not assign it if the documentation only mentions intoxication, dependence, or unspecified substance-related disorder.
Coding tip
Confirm both elements are documented: hallucinogen abuse and psychotic disorder with delusions.
