Toxic effect of other pesticides, undetermined, sequela

This code signifies a long-term or residual health problem resulting from exposure to an unspecified pesticide, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. These sequelae represent chronic conditions or lasting damage directly attributable to the past toxic effect.

Apply this code when a patient presents with a persistent health issue, such as chronic neurological deficits, organ damage, or dermatological conditions, that is documented as a direct consequence of a past, undetermined exposure to a pesticide other than those specifically classified. This code is appropriate when the acute phase of the poisoning has resolved, and the current encounter addresses the lasting effects.

• Always sequence this sequela code after the code for the specific manifestation of the sequela (e.g., a code for chronic kidney disease).
• Ensure documentation clearly links the current condition to a past pesticide exposure and explicitly states the undetermined intent.
• Avoid using this code for acute poisoning; instead, use the appropriate acute toxic effect code with the correct seventh character for initial or subsequent encounter.
