Poisoning by macrolides, accidental (unintentional), init

This code signifies an adverse health event resulting from an accidental overdose or unintended exposure to a macrolide antibiotic. The patient is experiencing the initial symptoms and complications of this poisoning, requiring immediate medical attention.

Apply this code when a patient presents with signs and symptoms of macrolide toxicity (e.g., gastrointestinal distress, cardiac arrhythmias, hearing loss) due to an accidental ingestion or misadministration. This is appropriate for the initial visit where the poisoning is first diagnosed and treated.

• Ensure documentation clearly states the poisoning was accidental and identifies a macrolide as the causative agent.
• Always sequence this code first as the primary diagnosis when it is the reason for the encounter.
• Consider additional codes for specific manifestations of the poisoning (e.g., R11.2 for nausea and vomiting, I49.9 for unspecified cardiac arrhythmia).
