ICD-10 Code F16.251 – Hallucinogen dependence with hallucinogen-induced psychotic disorder with hallucinations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.251 – Hallucinogen dependence with hallucinogen-induced psychotic disorder with hallucinations
What it is
This code identifies hallucinogen dependence together with a substance-induced psychotic disorder marked by hallucinations. Use it when the record shows ongoing hallucinogen use and psychotic symptoms caused by that use.
Clinical signs
Typical documentation may include hallucinations, delusions, disorganized thinking, or impaired perception 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 both hallucinogen dependence and a hallucinogen-induced psychotic disorder with hallucinations. The chart should link the psychotic symptoms to hallucinogen use, not to a primary psychotic disorder. If the record does not clearly state hallucinations or dependence, check documentation.
Do not use for
Do not use this code for hallucinogen use without dependence, or for psychosis unrelated to hallucinogen exposure. Also avoid it when the documentation does not confirm hallucinations; check documentation.
Coding tip
Assign the code only when both dependence and substance-induced psychosis with hallucinations are explicitly documented.
