Toxic effect of trichloroethylene, undetermined, sequela

This code signifies a long-term or late-onset health problem resulting from an exposure to trichloroethylene, where the intent of the exposure (e.g., accidental, intentional self-harm) cannot be determined. These sequelae are persistent conditions that arise after the acute phase of the toxic effect has passed.

Apply this code when documenting chronic neurological, hepatic, renal, or other organ damage that is definitively linked to a past trichloroethylene exposure, and the circumstances of that exposure are unknown or unspecified. This is appropriate for conditions like persistent peripheral neuropathy or chronic liver disease attributed to trichloroethylene, years after the initial event.

• Always sequence this sequela code after the code for the specific manifestation of the toxic effect (e.g., a code for peripheral neuropathy).
• Ensure documentation clearly links the current condition to a past trichloroethylene exposure and explicitly states the undetermined intent.
• Do not use this code for acute toxic effects; it is exclusively for residual conditions.
