Adverse effect of aminoglycosides, sequela

This code signifies a long-term or residual condition resulting from a past adverse reaction to an aminoglycoside antibiotic. It indicates that the patient is experiencing a permanent or chronic health problem directly attributable to the previous drug toxicity, even after the acute phase has resolved.

Apply this code when documenting a patient presenting with a chronic sequela, such as permanent hearing loss (ototoxicity) or persistent kidney damage (nephrotoxicity), definitively linked to prior aminoglycoside therapy. This code is appropriate for follow-up encounters addressing these lasting effects.

• Always sequence this code after the code for the specific sequela (e.g., H90.5 for sensorineural hearing loss).
• Ensure documentation clearly establishes the causal link between the aminoglycoside and the chronic condition.
• Do not use this code for acute adverse effects; refer to the appropriate acute adverse effect code for initial presentations.
