Toxic effect of rodenticides, undetermined, subs encntr

This code signifies a toxic reaction to rodenticides where the intent (accidental, intentional self-harm, assault) is not documented or cannot be determined. The patient is receiving follow-up care for the poisoning, such as monitoring for delayed effects or managing ongoing symptoms, after the initial treatment phase.

Apply this code for patients presenting for subsequent evaluation or treatment of rodenticide poisoning when the circumstances of exposure are unclear or unstated in the medical record. This includes situations where the patient is stable but requires ongoing management for residual symptoms or potential long-term complications.

• Always sequence this code after any codes for specific symptoms or conditions resulting from the toxic effect.
• Ensure documentation clearly indicates a "subsequent encounter" for the poisoning, not an initial presentation.
• If the intent of the poisoning is later clarified, update the code to reflect the specific intent (e.g., accidental, intentional self-harm).
