Toxic effect of herbicides and fungicides, undet, sequela

This code signifies a long-term health problem or complication resulting from a past exposure to herbicides or fungicides, where the specific intent of the exposure (accidental, intentional self-harm, assault) is unknown. It indicates that the patient is currently experiencing a residual effect directly attributable to that prior toxic event.

Use this code when a patient presents with a chronic condition, organ damage, or other lasting sequelae that a physician has definitively linked to a previous, unspecified toxic exposure to herbicides or fungicides. This applies when the acute phase of the poisoning has resolved, and the patient is now being treated for the ongoing, residual effects.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, neurological deficit).
• Ensure documentation clearly establishes the causal link between the prior herbicide/fungicide exposure and the current condition.
• Only use the "S" seventh character for sequela when the acute toxic event has passed and the patient is being treated for the residual effects.
