ICD-10 Code F16.95 – Hallucinogen use, unspecified with hallucinogen-induced psychotic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.95 – Hallucinogen use, unspecified with hallucinogen-induced psychotic disorder
What it is
This code identifies hallucinogen use when the patient has a psychotic disorder caused by that substance. It applies when the substance is not specified and the psychosis is linked to hallucinogen use.
Clinical signs
Clinical features vary; refer to documentation. Psychotic symptoms may include hallucinations, delusions, disorganized thinking, or marked behavioral disturbance that clinicians attribute to hallucinogen use.
When to use this code
Use this code when the record documents hallucinogen use, but the specific hallucinogen is not named, and the provider diagnoses hallucinogen-induced psychotic disorder. You should also use it when the psychosis is clearly substance-induced and not better explained by another primary psychotic disorder. Check documentation if the causal link is unclear.
Do not use for
Do not use this code for hallucinations or psychosis without a documented hallucinogen cause. If the substance is identified more specifically or the psychosis is unrelated to hallucinogen use, choose the appropriate different code.
Coding tip
Verify that the provider explicitly connects the psychotic disorder to hallucinogen use before assigning F16.95.
