Poisoning by aminoglycosides, accidental, subs

This code signifies an adverse health effect resulting from an unintended overdose or improper administration of an aminoglycoside antibiotic, occurring during a follow-up visit for the initial poisoning event. The patient is experiencing ongoing complications or receiving continued treatment related to the accidental exposure.

Apply this code when a patient presents for management of persistent symptoms, monitoring of organ function (e.g., renal, auditory), or treatment of complications (e.g., nephrotoxicity, ototoxicity) stemming from an accidental aminoglycoside poisoning that occurred previously. This indicates that the initial acute phase of the poisoning has passed, and the encounter is for ongoing care.

• Always use in conjunction with codes for the specific manifestations or complications of the poisoning (e.g., acute kidney injury, hearing loss).
• Ensure documentation clearly states the poisoning was accidental and that this is a subsequent encounter for ongoing care.
• Distinguish from initial encounters (A) or sequela encounters (S) based on the patient's current stage of care for the poisoning.
