Poisoning by tetracycline group

This code signifies an adverse reaction or overdose specifically caused by medications belonging to the tetracycline class of antibiotics. It encompasses both accidental and intentional ingestions leading to toxic effects, as well as adverse drug reactions occurring at therapeutic doses. The poisoning can manifest with various symptoms affecting multiple organ systems.

This code is appropriate when documentation clearly indicates a patient's condition is a direct result of poisoning by a tetracycline antibiotic. This includes scenarios such as acute overdose, chronic toxicity from prolonged use, or an idiosyncratic reaction to the drug. Supporting documentation should specify the tetracycline drug involved and the resulting clinical manifestations.

• Always sequence this code first if it represents the primary reason for the encounter.
• Utilize an E-code (E850.0-E858.9) to specify the external cause of poisoning (e.g., accidental, intentional self-harm).
• Code all manifestations of the poisoning (e.g., nausea, vomiting, renal failure) as additional diagnoses.
