ICD-10 Code F16.250 – Hallucinogen dependence with hallucinogen-induced psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.250 – Hallucinogen dependence with hallucinogen-induced psychotic disorder with delusions
What it is
This code identifies a hallucinogen use disorder with dependence, plus a psychotic disorder caused by the hallucinogen and marked by delusions. It indicates both ongoing substance dependence and a substance-induced mental disorder.
Clinical signs
Typical findings include compulsive use, difficulty controlling use, and continued use despite harm, along with delusional thinking linked to hallucinogen exposure. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents hallucinogen dependence and a hallucinogen-induced psychotic disorder with delusions. You should assign it when the psychosis is attributed to the substance, not to a primary psychotic disorder.
Use the code only when the provider links both conditions in the assessment or discharge diagnosis. If the chart is unclear about the substance, dependence, or psychotic features, check documentation before coding.
Do not use for
Do not use this code for hallucinogen use without dependence, or for psychosis not documented as substance-induced. Do not assume delusions are caused by hallucinogens without provider confirmation.
Coding tip
Look for explicit provider wording connecting dependence, hallucinogen use, and delusions before assigning F16.250.
