Toxic effect of rodenticides, accidental, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from an unintentional poisoning by a rodenticide. The initial exposure and acute effects have already been addressed, and the patient is now in a recovery or management phase. This indicates that the toxic effects are still present or being monitored after the initial incident.

Apply this code when a patient returns for subsequent evaluation or treatment related to an accidental rodenticide exposure. This includes scenarios such as monitoring liver function, managing persistent neurological symptoms, or addressing delayed toxic effects after the initial emergency visit. It is appropriate for any encounter following the initial acute care for the poisoning.

• Ensure documentation clearly states "accidental" or "unintentional" exposure to rodenticides.
• Confirm this is a follow-up encounter, not the initial presentation for the poisoning.
• Always code the specific toxic effect(s) as additional diagnoses if known and documented.
