Poisoning by macrolides, undetermined, initial encounter

This code signifies an adverse event resulting from exposure to a macrolide antibiotic, where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined at the time of the initial encounter. The patient is experiencing the acute effects of the macrolide overdose or toxicity.

Apply this code when a patient presents with signs and symptoms of macrolide poisoning, and the medical record does not specify whether the exposure was accidental, intentional, or due to an assault. This is appropriate for the initial visit for treatment of the poisoning.

• Always assign an additional code for the specific macrolide antibiotic if known (from categories T36.3X1-T36.3X6).
• Do not use this code if the intent of the poisoning is clearly documented (e.g., accidental, intentional self-harm).
• Remember the "A" suffix indicates an initial encounter for the poisoning event. Subsequent care would use "D" or "S."
