Toxic effect of tetrachloroethylene, accidental, init

This code signifies an adverse health effect resulting from accidental exposure to tetrachloroethylene, a chemical commonly used as a dry-cleaning solvent and degreaser. The toxic effect can manifest in various organ systems, including the central nervous system, liver, and kidneys, depending on the route and duration of exposure. Symptoms may range from dizziness and headache to more severe organ damage.

Apply this code when documenting a patient presenting with symptoms or signs of tetrachloroethylene poisoning due to an unintentional exposure. This includes cases such as accidental inhalation in occupational settings, skin contact during handling, or ingestion of contaminated substances. This specific code is for the initial encounter for treatment of the acute toxic effects.

• Ensure documentation clearly states "accidental" or "unintentional" exposure to tetrachloroethylene.
• Confirm this is the patient's first encounter for this specific toxic event; subsequent encounters will require different seventh characters.
• Always code any specific manifestations of the toxicity (e.g., acute hepatic failure, toxic encephalopathy) in addition to this code.
