Hallucinogen dependence, uncomplicated

This code signifies a patient's physiological and psychological reliance on hallucinogenic substances, such as LSD, psilocybin, or PCP, without any associated complications. It indicates a pattern of compulsive drug-seeking behavior and continued use despite negative consequences, often accompanied by tolerance and withdrawal symptoms upon cessation. The "uncomplicated" specifier means there are no co-occurring substance-induced psychotic, mood, or anxiety disorders.

Apply this code when documentation clearly indicates a diagnosis of hallucinogen dependence without any acute intoxication, withdrawal, or other substance-induced mental health conditions. This is appropriate for patients undergoing treatment for their dependence or for chronic management. Supporting documentation should detail the pattern of hallucinogen use, evidence of dependence criteria (e.g., tolerance, withdrawal, unsuccessful attempts to cut down), and explicitly state the absence of complications.

• Ensure documentation explicitly rules out hallucinogen-induced psychotic, mood, or anxiety disorders before assigning this "uncomplicated" code.
• Do not use this code for acute hallucinogen intoxication or withdrawal; separate codes exist for those conditions.
• Always sequence this code as a primary diagnosis when it is the focus of the encounter, or as a secondary diagnosis when dependence is a co-morbidity impacting treatment.
