Hallucinogen abuse w hallucinogen-induced anxiety disorder

This code signifies a pattern of problematic hallucinogen use leading to clinically significant impairment or distress, specifically characterized by the co-occurrence of an anxiety disorder directly induced by hallucinogen intoxication or withdrawal. The anxiety symptoms are prominent and exceed what would be expected during uncomplicated intoxication or withdrawal.

Apply this code when documentation clearly indicates a diagnosis of hallucinogen abuse alongside an anxiety disorder that is directly attributable to the hallucinogen use. This typically involves a temporal relationship between substance use and anxiety onset, and the anxiety symptoms are not better explained by another mental disorder. Supporting documentation includes psychiatric evaluations, substance use assessments, and detailed clinical notes outlining the causal link.

• Ensure documentation explicitly links the anxiety disorder to hallucinogen use, ruling out pre-existing or independent anxiety conditions.
• Do not use this code if the anxiety is merely a transient symptom of acute intoxication or withdrawal without meeting criteria for a distinct anxiety disorder.
• Consider sequencing this code as a primary diagnosis when the hallucinogen abuse with induced anxiety is the primary reason for the encounter.
