Adverse effect of aminoglycosides, initial encounter

This code signifies an undesirable or harmful reaction experienced by a patient due to the therapeutic use of an aminoglycoside antibiotic. These adverse effects can range from mild to severe and are not due to overdose or poisoning, but rather an expected or unexpected side effect when the drug is administered correctly.

Apply this code when documenting the initial presentation or treatment of a patient experiencing an adverse reaction to an aminoglycoside, such as ototoxicity, nephrotoxicity, or neuromuscular blockade. This code is appropriate for the first time a patient seeks care for the specific adverse effect.

• Always sequence this code after the code for the specific manifestation of the adverse effect (e.g., code for acute kidney failure).
• Ensure documentation clearly states the reaction is an adverse effect and not poisoning or underdosing.
• For subsequent encounters related to the same adverse effect, use the appropriate subsequent encounter (D) or sequela (S) seventh character.
