Toxic eff of halgn deriv of aromatic hydrocrb, asslt, init

This code signifies the adverse health effects resulting from intentional poisoning by halogenated aromatic hydrocarbons, excluding those specifically classified elsewhere (e.g., PCBs, dioxins). It indicates that the patient is in the acute phase of treatment for this toxic exposure.

Apply this code when a patient presents with symptoms of poisoning due to deliberate exposure to an unclassified halogenated aromatic hydrocarbon, such as certain pesticides or industrial chemicals. This is appropriate for the initial encounter where diagnosis and active treatment for the toxic effect are being rendered.

• Always use in conjunction with an external cause code (Y90-Y99) to specify the intent and circumstances of the assault.
• Ensure documentation clearly states the substance involved is a halogen derivative of an aromatic hydrocarbon and that the exposure was intentional (assault).
• This "initial encounter" seventh character is used as long as the patient is receiving active treatment for the toxic effect.
