Poisoning by unsp systemic antibiotic, undetermined, sequela

This code signifies a long-term or residual effect resulting from an exposure to an unspecified systemic antibiotic, where the intent of the exposure (e.g., accidental, intentional self-harm) cannot be determined. These sequelae are the lasting health problems or conditions that persist after the initial poisoning event has resolved.

Assign this code when documenting a patient presenting with a chronic or permanent condition directly attributable to a past poisoning by a systemic antibiotic, and the specific type of antibiotic is not documented. This code is appropriate when the circumstances surrounding the poisoning event are unclear or unknown.

• Always use a seventh character of "S" for sequela, indicating a complication or condition arising as a direct result of a previous injury or disease.
• Ensure documentation clearly links the current condition to a past poisoning event by an unspecified systemic antibiotic.
• Avoid using this code for acute poisoning events; instead, use the appropriate acute poisoning code with a seventh character of "A" or "D."
