ICD-10 Code F16.92 – Hallucinogen use, unspecified with intoxication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.92 – Hallucinogen use, unspecified with intoxication
What it is
This code identifies a current intoxication state from hallucinogen use when the specific substance is not documented. It applies when the patient has acute effects from a hallucinogenic drug, but the record does not name the agent.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include altered perception, impaired judgment, anxiety, agitation, confusion, or perceptual disturbances consistent with intoxication.
When to use this code
Use F16.92 when the provider documents hallucinogen intoxication and does not specify the drug. It is appropriate for encounters focused on acute effects, emergency evaluation, or observation after recent use. Code the documented substance instead if the record identifies it.
Do not use for
Do not use this code for hallucinogen dependence, abuse without intoxication, or withdrawal. Check documentation if the presentation is due to another substance, a mental disorder, or an unspecified psychoactive substance.
Coding tip
Assign the most specific hallucinogen code available; use F16.92 only when intoxication is documented and the agent remains unspecified.
