Poisoning by sulfonamides, assault, subsequent encounter

This code signifies a patient presenting for follow-up care or recovery from an intentional overdose or adverse reaction to a sulfonamide antibiotic, where the poisoning was inflicted by another person. It indicates that the initial treatment for the acute poisoning has already been provided.

Use this code for subsequent encounters when a patient is receiving ongoing management, monitoring, or rehabilitation for poisoning by sulfonamides that occurred as a result of an assault. This includes visits for medication adjustments, symptom management, or psychological support related to the event.

• Always sequence this code after the primary diagnosis for the specific manifestation of the poisoning.
• Ensure documentation clearly specifies "assault" as the intent and that it is a "subsequent encounter."
• Do not use for initial encounters or for accidental or self-harm poisonings.
