Toxic effect of unspecified pesticide, assault, sequela

This code signifies a long-term or residual health problem resulting from a past poisoning by an unknown pesticide, where the exposure was intentionally inflicted by another person. It indicates that the acute phase of the poisoning has resolved, but the patient continues to experience lasting effects.

Apply this code when documenting chronic conditions, disabilities, or persistent symptoms directly attributable to a previous assault by an unspecified pesticide. This is appropriate for follow-up encounters after the initial acute toxic event has been treated and the patient is presenting for management of the sequelae.

• Always ensure documentation clearly links the current condition to the past pesticide assault.
• Requires a seventh character of "S" for sequela, indicating the long-term effects.
• Do not use for acute poisoning; reserve for residual or late effects.
