Poisoning by tetracyclines, undetermined, initial encounter

This diagnosis code indicates a case of poisoning resulting from exposure to a tetracycline antibiotic, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined from the available documentation. The "initial encounter" designation signifies that this is the first time the patient is receiving active treatment for this specific poisoning.

This code is appropriate when a patient presents with adverse effects or toxicity due to a tetracycline, and the medical record does not specify whether the poisoning was accidental, intentional, or due to an assault. It is used for the initial visit or admission for the management of the poisoning.

• Always review documentation for intent (accidental, intentional, assault) to select a more specific 5th character if possible.
• Ensure the encounter is truly the "initial" treatment for this poisoning; subsequent care would use a different 7th character.
• Code any associated signs, symptoms, or adverse effects of the poisoning in addition to this code.
