Toxic effect of xylazine, assault, initial encounter

This code signifies a harmful physiological response resulting from the intentional administration of xylazine to another individual with the intent to cause harm. The patient is in the acute phase of treatment for this toxic effect.

Apply this code when documenting a patient presenting with symptoms of xylazine toxicity, and the medical record clearly indicates the exposure was due to an assault. This is appropriate for the initial encounter for treatment of the acute toxic effects.

• Ensure documentation explicitly states "assault" or similar intent to differentiate from accidental or self-harm.
• Always assign an additional code for the specific manifestations of the xylazine toxicity.
• This "A" initial encounter character is used for the period when the patient is receiving active treatment for the toxic effect.
