Poisoning by oth systemic antibiotics, accidental, subs

This code signifies an adverse health effect resulting from an unintended overdose or improper administration of a systemic antibiotic other than those specifically classified elsewhere (e.g., penicillins, macrolides). The patient is in the subsequent phase of care for this poisoning event, meaning they are receiving ongoing treatment or follow-up after the initial acute management.

Use this code for follow-up visits or ongoing treatment related to an accidental poisoning by a systemic antibiotic not otherwise specified. This includes scenarios where a patient is being monitored for lingering side effects, undergoing detoxification, or receiving supportive care after the initial emergency treatment for the poisoning.

• Always use in conjunction with an external cause code (e.g., Y92.-, Y93.-, Y90.-) to provide more detail about the circumstances of the poisoning.
• Ensure the "D" seventh character is appropriate for subsequent encounters; "A" is for initial, "S" for sequela.
• Verify the specific antibiotic involved to ensure it falls under "other systemic antibiotics" and not a more specific category.
