ICD-10 Code F16.12 – Hallucinogen abuse with intoxication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.12 – Hallucinogen abuse with intoxication
What it is
Use this code for a documented pattern of hallucinogen abuse with current intoxication. It indicates active substance use causing acute effects, not just historical use or dependence.
Clinical signs
Clinical features vary; refer to documentation. Common intoxication findings may include altered perception, impaired judgment, anxiety, agitation, or perceptual disturbances after hallucinogen use.
When to use this code
Use F16.12 when the record clearly states hallucinogen abuse and intoxication together. Apply it when the clinician documents acute intoxication from a hallucinogen and the use pattern is described as abuse. Check documentation if the substance is unspecified or the type of use is unclear.
Do not use for
Do not use this code for hallucinogen dependence, uncomplicated hallucinogen use, or intoxication without documented abuse. If the drug class or diagnosis is not specified, check documentation.
Coding tip
Code the documented substance and the intoxication status exactly as stated; do not assume abuse from intoxication alone.
