Toxic effect of xylazine, self-harm, subsequent encounter

This code signifies a toxic reaction resulting from the deliberate self-administration of xylazine, a veterinary tranquilizer. The patient is presenting for follow-up care or treatment of sequelae after the initial acute poisoning event. This indicates the initial toxic exposure has already been addressed.

Apply this code when documenting a patient's visit for ongoing management of complications, rehabilitation, or monitoring related to a previous intentional xylazine overdose. This would include scenarios where the patient is seen in an outpatient setting for psychiatric evaluation following the event, or for treatment of lingering physical effects. It is used after the initial acute care for the poisoning has been rendered.

• Ensure documentation clearly states "intentional self-harm" and that the encounter is for follow-up care.
• Do not use for the initial acute poisoning encounter; that would require an initial encounter seventh character.
• Always sequence this code after any codes for the specific manifestations or complications of the xylazine toxicity.
