Toxic effect of unsp pesticide, undetermined, subs encntr

This code signifies a toxic reaction to an unknown pesticide where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. It is used for encounters following the initial treatment of the poisoning.

Apply this code when a patient presents for follow-up care, such as monitoring, further treatment, or evaluation of residual effects, after an initial diagnosis of poisoning by an unspecified pesticide. The original incident's intent must remain undetermined.

• Requires a seventh character "D" for subsequent encounter.
• Ensure the medical record explicitly states that the specific pesticide is unknown and the intent is undetermined.
• Do not use for initial encounters; refer to codes ending in "A".
