Poisoning by macrolides, undetermined, subsequent encounter

This code signifies a patient presenting for follow-up care or ongoing treatment related to a poisoning event caused by a macrolide antibiotic. The original intent of the poisoning (e.g., accidental, intentional self-harm) could not be determined at the time of initial assessment.

Apply this code when a patient returns for subsequent care, such as medication adjustments, monitoring for lingering effects, or management of complications, after an initial encounter for macrolide poisoning where the intent was unknown. This includes situations where the patient is stable but still requires medical attention for the poisoning.

• Ensure the encounter is for follow-up care, not the initial presentation of the poisoning.
• Verify documentation explicitly states "undetermined intent" for the poisoning.
• Always sequence this code after any codes for specific manifestations or complications of the poisoning.
