Other stimulant use, unspecified with intoxication delirium

This code signifies a diagnosis of stimulant use disorder, unspecified as to severity or specific stimulant, accompanied by an acute state of delirium due to intoxication. The patient exhibits altered consciousness, cognitive impairment, and perceptual disturbances directly attributable to recent stimulant use.

Apply this code when documentation clearly indicates a patient is experiencing delirium as a direct result of acute intoxication from an unspecified stimulant. This requires a physician's diagnosis of both stimulant use (without specifying the substance like amphetamine or cocaine) and delirium caused by the intoxication.

• Ensure documentation explicitly links the delirium to stimulant intoxication; do not assume causality.
• If the specific stimulant (e.g., cocaine, amphetamine) is identified, a more specific code from the F15.xx category should be used.
• Sequence this code as the primary diagnosis when the delirium is the main reason for the encounter.
