ICD-10 Code F16.10 – Hallucinogen abuse, uncomplicated (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F16.10 – Hallucinogen abuse, uncomplicated
What it is
F16.10 identifies hallucinogen abuse without documented complications. Use it when the record shows harmful or problematic use of a hallucinogen, but no intoxication, dependence, psychosis, or other specified disorder is documented.
Clinical signs
Clinical features vary; refer to documentation. Records may note repeated use despite harm, impaired judgment, or social and occupational problems linked to hallucinogen use.
When to use this code
Use F16.10 when the clinician documents hallucinogen abuse and does not specify intoxication, dependence, or a substance-induced disorder. It is appropriate for uncomplicated cases where the only confirmed diagnosis is abuse. If the note is unclear, check documentation before coding.
Do not use for
Do not use this code for hallucinogen intoxication, dependence, or hallucinogen-induced psychotic disorder. If the chart describes another substance or a more specific condition, code that diagnosis instead.
Coding tip
Confirm the substance and the exact provider wording; “abuse” alone supports F16.10 only when no complication is documented.
