Toxic effect of xylazine, undetermined, sequela

This code signifies the long-term or residual effects resulting from an exposure to xylazine where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. These sequelae are persistent conditions that arise after the acute toxic effects of xylazine have resolved.

Apply this code when documenting chronic health problems or permanent damage directly attributable to a past xylazine exposure, and the circumstances surrounding the exposure remain unknown or unspecified. This is appropriate for follow-up encounters addressing these lasting complications, not for the initial acute poisoning event.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Do not use this code for acute xylazine toxicity; instead, use the appropriate acute poisoning code.
• Ensure documentation clearly links the current condition to a past xylazine exposure with an undetermined intent.
