Poisoning by tetracyclines, intentional self-harm, init

This code signifies a deliberate act of self-poisoning involving tetracycline antibiotics. It indicates that the patient intentionally ingested an overdose of this medication with the intent to harm themselves, and this is the first time they are being treated for this specific event.

Apply this code when documentation clearly states a patient presented due to an intentional overdose of a tetracycline drug, such as doxycycline or minocycline, as a form of self-harm. This code is appropriate for the initial hospital visit or emergency department encounter for this specific poisoning episode.

• Always confirm the intent (intentional self-harm) and the specific drug class (tetracyclines) from the medical record.
• Ensure the encounter is the "initial encounter" for this poisoning event; subsequent care would use a different seventh character.
• Code any associated mental health conditions, such as depression or suicidal ideation, as additional diagnoses.
