Toxic effect of trichloroethylene, assault, subs encntr

This code signifies the adverse health effects resulting from exposure to trichloroethylene, a volatile organic compound, when the exposure was intentionally inflicted by another person. The "subsequent encounter" indicates that the patient is receiving follow-up care for the sequelae of this toxic exposure after the initial treatment.

This code is appropriate for documenting ongoing medical management, such as monitoring organ function, managing chronic symptoms, or providing rehabilitation, for a patient who was poisoned by trichloroethylene in an assault. It should be used for visits occurring after the initial acute treatment of the poisoning event.

• Always sequence this code after the primary diagnosis indicating the specific manifestation of the toxic effect (e.g., acute kidney injury, neurological damage).
• Ensure documentation clearly supports an "assault" as the intent of exposure and that the encounter is for follow-up care.
• Do not use for initial acute care of the poisoning; a code with an "A" (initial encounter) seventh character would be appropriate for that scenario.
