Poisoning by macrolides, undetermined, sequela

This code indicates a long-term or residual effect resulting from a macrolide antibiotic poisoning where the intent (e.g., accidental, intentional self-harm) could not be determined at the time of the initial event. These sequelae are the chronic conditions or complications that persist after the acute phase of the poisoning has resolved.

Apply this code when documenting a patient presenting with a chronic health issue directly attributable to a past macrolide poisoning, and the original poisoning event's intent was never established. This is used for follow-up encounters addressing the lasting effects, not the initial acute poisoning. Examples include persistent organ damage or neurological deficits.

• Always sequence this 'S' code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past macrolide poisoning of undetermined intent.
• Do not use this code for acute poisoning events; it is exclusively for residual effects.
