Poisoning by fluoroquinolone antibiot, accidental, sequela

This code signifies a long-term or residual effect resulting from an accidental overdose or unintended exposure to fluoroquinolone antibiotics. These sequelae can manifest in various body systems, such as persistent tendinopathy, neuropathy, or central nervous system disturbances, that are directly attributable to the prior poisoning event.

Use this code when documenting a patient presenting with a chronic condition or permanent damage that is a direct consequence of an accidental fluoroquinolone poisoning that occurred in the past. This applies when the acute poisoning event has resolved, but its lasting impact requires ongoing medical attention.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., M76.89 for other specified enthesopathies of lower limb, not elsewhere classified, if tendinopathy is the sequela).
• Ensure documentation clearly links the current condition to a past accidental fluoroquinolone poisoning.
• Do not use this code for acute poisoning events; use the acute poisoning codes for initial encounters.
