Poisoning by aminoglycosides, accidental, sequela

This code signifies a long-term or residual effect resulting from an accidental overdose or unintended adverse reaction to an aminoglycoside antibiotic. These sequelae can manifest as permanent hearing loss, kidney damage, or other lasting complications that developed after the initial poisoning event.

Apply this code when documenting a patient presenting with a chronic condition directly attributable to a past, unintentional aminoglycoside poisoning. This would include scenarios where a patient is being treated for permanent ototoxicity or nephrotoxicity that occurred due to an accidental administration error or miscalculation of an aminoglycoside.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., H90.5 for sensorineural hearing loss).
• Ensure documentation clearly links the current condition to a past accidental aminoglycoside poisoning.
• Verify the poisoning was accidental; intentional poisonings would use a different seventh character.
