Poisoning by rifampicins, accidental (unintentional), subs

This code signifies an accidental overdose or adverse reaction to rifampicin, an antibiotic commonly used to treat tuberculosis and other bacterial infections, during a subsequent phase of care. The patient is experiencing ongoing effects or complications from the initial poisoning event, requiring continued medical attention.

Apply this code when a patient presents for follow-up care, monitoring, or treatment of complications arising from an unintentional rifampicin poisoning. This includes scenarios where the patient is recovering from the acute event but still requires management of organ damage, persistent symptoms, or adverse drug effects.

• Ensure documentation clearly states the poisoning was accidental and this is not the initial encounter for the poisoning.
• Always sequence this code after the primary diagnosis for the specific manifestation of the poisoning (e.g., acute kidney injury, hepatotoxicity).
• Consider additional codes for any associated symptoms, complications, or external causes (e.g., Y92.009 for place of occurrence if known).
