Hallucinogen dependence with intoxication, uncomplicated

This code signifies a patient's physiological and psychological dependence on hallucinogens, accompanied by acute intoxication without additional complications. It indicates a pattern of hallucinogen use leading to tolerance, withdrawal symptoms, and continued use despite negative consequences, with the immediate presentation being the intoxicating effects of the substance.

Apply this code when documentation clearly states hallucinogen dependence and current intoxication, and there are no further specified complications such as delirium, psychotic disorder, or mood disorder. This is appropriate for patients presenting with acute hallucinogen effects in the context of an established dependence. Documentation should explicitly mention both dependence and intoxication.

• Do not use this code if the intoxication is complicated by other mental or behavioral disorders; instead, select a more specific code from the F16.2xx series.
• Ensure documentation differentiates between hallucinogen abuse and dependence; this code is specific to dependence.
• Consider sequencing this code as a primary diagnosis if the intoxication is the reason for the encounter, or as a secondary diagnosis if another condition is the primary reason for admission/visit.
