Poisoning by antifungal antibiotics, sys used, undet, init

This code signifies an adverse reaction or overdose from an antifungal medication taken systemically, where the intent (e.g., accidental, intentional self-harm) cannot be determined. The patient is experiencing the initial effects of this poisoning.

Apply this code when a patient presents with symptoms of antifungal toxicity, and the medical record does not specify whether the poisoning was accidental, intentional, or due to therapeutic error. This is appropriate for the first encounter for this specific poisoning event.

• Always assign an additional code for the specific antifungal antibiotic involved, if known.
• Do not use this code if the intent of the poisoning is clearly documented (e.g., accidental, intentional self-harm).
• Ensure the "A" seventh character for "initial encounter" is appropriate for the patient's visit.
