Poisoning by fluoroquinolone antibiotics, undet, sequela

This code signifies a long-term or residual effect resulting from a past poisoning event involving fluoroquinolone antibiotics, where the intent of the poisoning (e.g., accidental, intentional self-harm) cannot be determined. These sequelae can manifest as various chronic conditions affecting different body systems, such as persistent neurological issues, musculoskeletal pain, or organ damage, that are directly attributable to the prior fluoroquinolone exposure.

Use this code when documenting a patient presenting with a chronic condition or permanent injury that is a direct consequence of a previous fluoroquinolone poisoning, and the medical record does not specify whether the poisoning was accidental, intentional, or assault. This code is appropriate for follow-up encounters addressing these lasting effects, not the acute poisoning event itself.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic neuropathy, tendon rupture).
• Ensure documentation clearly links the current condition to a past fluoroquinolone poisoning.
• Do not use this code for acute poisoning events; instead, use the appropriate acute poisoning code with the correct intent.
