Poisoning by macrolides, assault, subsequent encounter

This code signifies a patient presenting for follow-up care related to an intentional overdose or poisoning by a macrolide antibiotic, where the poisoning was inflicted by another person. The patient is no longer in the acute phase of treatment but is receiving ongoing management for the effects of the assault.

Use this code for subsequent encounters when a patient is being treated for complications, sequelae, or ongoing management stemming from a macrolide poisoning that was determined to be an assault. This includes follow-up appointments for organ damage, psychological support, or monitoring after the initial acute care has been rendered.

• Always assign an additional code for the specific macrolide antibiotic involved, if known.
• Ensure documentation clearly indicates the poisoning was an assault and that this is a subsequent encounter.
• Do not use this code for the initial acute treatment of the poisoning; use the appropriate initial encounter code instead.
