ICD-10 Code F16.950 – Hallucinogen use, unspecified with hallucinogen-induced psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.950 – Hallucinogen use, unspecified with hallucinogen-induced psychotic disorder with delusions
What it is
This code identifies hallucinogen use, unspecified, with a psychotic disorder marked by delusions. Use it when documentation links hallucinogen exposure to delusional psychosis.
Clinical signs
Typical findings include fixed false beliefs, impaired reality testing, and behavior or speech affected by psychosis. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states hallucinogen use and a hallucinogen-induced psychotic disorder with delusions. It also fits when the substance is not named more specifically, but the psychotic relationship is documented. Check documentation if the psychosis is better explained by another condition.
Do not use for
Do not use this code for hallucinations without delusions, or for psychosis not linked to hallucinogen use. Do not assign it when the substance is specified differently and another code is more appropriate.
Coding tip
Confirm both the hallucinogen use and the induced delusional psychosis are documented before coding.
