ICD-10 Code F16.25 – Hallucinogen dependence with hallucinogen-induced psychotic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.25 – Hallucinogen dependence with hallucinogen-induced psychotic disorder
What it is
F16.25 identifies dependence on hallucinogens with a psychotic disorder caused by hallucinogen use. Use it when documentation shows both ongoing dependence and hallucinations, delusions, or other psychotic features linked to the substance.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include psychosis temporally associated with hallucinogen use, such as hallucinations, delusions, disorganized thinking, or impaired reality testing.
When to use this code
Use this code when the provider documents hallucinogen dependence and a hallucinogen-induced psychotic disorder in the same encounter. It may apply during evaluation, inpatient care, or follow-up when the psychotic disorder remains clinically relevant.
Do not assume the diagnosis from intoxication alone. Code only when the record clearly supports dependence and psychosis caused by hallucinogen use; otherwise, check documentation.
Do not use for
Do not use this code for uncomplicated hallucinogen use, intoxication, or dependence without psychotic disorder. Also avoid it when psychosis is documented as unrelated to hallucinogen use.
Coding tip
Confirm both elements in the chart: hallucinogen dependence and hallucinogen-induced psychosis, because either diagnosis alone points to a different code.
