Other stimulant abuse with intoxication delirium

This code signifies a diagnosis of abuse of stimulants (e.g., amphetamines, methamphetamines, cocaine) accompanied by an acute state of delirium resulting from intoxication. Delirium is characterized by an acute disturbance in attention, awareness, and cognition, which is directly attributable to the physiological effects of the stimulant.

Apply this code when documentation clearly indicates a patient's stimulant abuse and a co-occurring, acute confusional state directly caused by the stimulant's intoxicating effects. Supporting documentation should include evidence of stimulant use, symptoms consistent with delirium (e.g., disorientation, fluctuating consciousness, hallucinations), and a physician's assessment linking the delirium to the stimulant intoxication.

• Always ensure the documentation explicitly states "abuse" of stimulants, not just "use" or "dependence," and specifies the presence of delirium due to intoxication.
• Differentiate from F15.129 (Other stimulant abuse with intoxication, unspecified) when delirium is clearly documented.
• Sequence this code as the primary diagnosis when the stimulant abuse with intoxication delirium is the reason for the encounter.
