Poisoning by oth systemic antibiotics, undetermined, sequela

This code signifies a long-term or residual effect resulting from a poisoning event involving a systemic antibiotic not otherwise specified, where the intent of the poisoning (accidental, intentional self-harm, assault, or undetermined) could not be established at the time of the initial event. It indicates that the patient is currently experiencing a health problem directly attributable to a past, unclarified exposure to an "other systemic antibiotic."

Use this code when documenting a patient presenting with a chronic condition or lasting complication that is a direct consequence of a previous poisoning by a systemic antibiotic (e.g., a fluoroquinolone, macrolide, or other unlisted systemic antibiotic) where the intent of the original poisoning was never determined. This applies to follow-up encounters for ongoing management of these sequelae, long after the acute poisoning has resolved.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic kidney disease, neuropathy).
• Ensure documentation clearly links the current condition to a past poisoning by an "other systemic antibiotic" and explicitly states the undetermined intent.
• Do not use this code for acute poisoning events; use the appropriate acute poisoning code with a 7th character of A, D, or G.
