Poisoning by tetracyclines, accidental, sequela

This code indicates a long-term health problem or complication resulting from an accidental overdose or unintended exposure to tetracycline antibiotics. The initial poisoning event has resolved, but the patient is now experiencing a residual effect or sequela directly attributable to that past event.

Apply this code when documenting a patient presenting with a chronic condition, organ damage, or other lasting adverse effect that is a direct consequence of a previously sustained, unintentional tetracycline poisoning. This is appropriate for follow-up encounters addressing the sequelae, not the acute poisoning itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., kidney damage, dental discoloration).
• Ensure the medical record clearly links the current condition to a past accidental tetracycline poisoning.
• Do not use for acute poisoning events; those require codes from the acute poisoning chapters.
