Hallucinogen abuse with other hallucinogen-induced disorder

This code signifies a pattern of problematic hallucinogen use leading to clinically significant impairment or distress, specifically when other hallucinogen-induced mental health conditions are present. This includes disorders such as hallucinogen-induced anxiety disorder, mood disorder, or psychotic disorder, but not intoxication or withdrawal.

Use this code when documentation clearly indicates a diagnosis of hallucinogen abuse alongside a co-occurring hallucinogen-induced disorder other than intoxication or withdrawal. This typically applies when a patient presents with persistent psychiatric symptoms directly attributable to hallucinogen use, and the use meets criteria for abuse.

• Ensure documentation specifies "abuse" and not "dependence" or "use, unspecified."
• Do not use this code for acute hallucinogen intoxication (F16.129) or withdrawal (F16.139).
• Code the specific hallucinogen-induced disorder (e.g., F16.181 for hallucinogen-induced psychotic disorder) as a secondary diagnosis if further specificity is documented.
