Poisoning by fluoroquinolone antibiotics, accidental, subs

This code signifies an adverse health event resulting from the unintended ingestion or exposure to a fluoroquinolone antibiotic, occurring during a follow-up visit for the initial poisoning. The patient is experiencing ongoing effects or complications from the accidental poisoning, which is not a new event.

Apply this code when a patient presents for follow-up care related to an accidental fluoroquinolone poisoning that was previously treated. This includes visits for monitoring residual symptoms, managing persistent side effects, or assessing the long-term impact of the initial toxic exposure.

• Always sequence this code after the primary diagnosis for the specific manifestation of the poisoning.
• Ensure documentation clearly states the poisoning was accidental and this is a subsequent encounter for the same event.
• Do not use for intentional overdose or adverse effects from therapeutic use; those require different codes.
