Adverse effect of fluoroquinolone antibiotics, sequela

This code signifies a long-term or residual condition resulting from a previous adverse reaction to fluoroquinolone antibiotics. These sequelae can manifest in various body systems, including musculoskeletal, neurological, and psychiatric. The adverse effect is no longer acute but has left a lasting impact on the patient's health.

Apply this code when documenting a chronic or permanent health problem directly attributable to a past adverse effect of fluoroquinolone antibiotics. This is appropriate for conditions like persistent peripheral neuropathy, chronic tendinopathy, or lasting psychiatric disturbances that developed after fluoroquinolone exposure and are now considered sequelae. It should be used when the acute adverse event has resolved, but its lasting consequences are being treated or monitored.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., G60.3 for iatrogenic neuropathy).
• Ensure documentation clearly links the current condition to a prior fluoroquinolone adverse effect.
• Distinguish from acute adverse effects (T36.AX5A) or subsequent encounters for the initial adverse effect (T36.AX5D).
