This is for the initial visit where the acute effects of the exposure are being evaluated and treated.

• Ensure the documentation clearly states the exposure was accidental and identifies the substance as an "other halogen derivative of an aromatic hydrocarbon."
• Always use this "A" initial encounter seventh character for the first time the patient is seen for this specific toxic effect.
• Code any specific symptoms or manifestations of the toxic effect in addition to this code.
