Toxic effect of trichloroethylene, accidental, sequela

This code signifies the long-term or residual effects resulting from an accidental exposure to trichloroethylene. It indicates that the acute toxic event has passed, but the patient is still experiencing health problems directly attributable to that past poisoning. These sequelae can manifest in various organ systems, such as neurological, hepatic, or renal damage.

Apply this code when documenting chronic conditions or permanent damage that developed as a direct consequence of an unintentional trichloroethylene poisoning. This would be used after the acute phase of the poisoning has resolved, and the patient is being treated for the lasting impact of the exposure. Examples include chronic liver disease, persistent neurological deficits, or kidney dysfunction linked to a past accidental trichloroethylene intoxication.

• Always ensure documentation clearly links the current condition to a past accidental trichloroethylene exposure.
• Do not use this code for acute poisoning; it is specifically for the sequelae (late effects).
• Code any specific manifestations of the sequela (e.g., chronic hepatitis, peripheral neuropathy) in addition to this code.
