Hallucinogen use, unsp w anxiety disorder

This code signifies a patient's problematic pattern of hallucinogen use that has led to the development of an anxiety disorder. The specific hallucinogen used is not documented, and the anxiety symptoms are directly attributable to the substance's effects. This diagnosis indicates a clinically significant impairment or distress caused by both the substance use and the resulting anxiety.

Use this code when documentation clearly indicates a diagnosis of hallucinogen use disorder, but the specific hallucinogen (e.g., LSD, PCP) is not specified. Crucially, there must be a documented anxiety disorder that is directly induced by the hallucinogen use, rather than a pre-existing or co-occurring anxiety condition. Supporting documentation would include a psychiatric evaluation, substance use history, and a clear causal link between hallucinogen use and anxiety symptoms.

• Ensure the documentation explicitly states "unspecified" hallucinogen use. If the specific hallucinogen is known, a more precise code should be used.
• Verify that the anxiety disorder is explicitly stated as "hallucinogen-induced" and not a separate, primary anxiety diagnosis.
• This code requires both the substance use and the induced mental health condition to be present and documented.
