Toxic effect of tetrachloroethylene, accidental, sequela

This code signifies the long-term or residual health problems resulting from an accidental exposure to tetrachloroethylene. These sequelae can manifest in various organ systems, such as neurological damage, liver dysfunction, or kidney impairment, occurring after the acute phase of the poisoning has passed.

Use this code when documenting chronic conditions or lasting health issues directly attributed to an unintentional tetrachloroethylene poisoning that occurred in the past. This applies to follow-up encounters for patients experiencing persistent symptoms or complications from such an exposure.

• Always use this code as a secondary diagnosis, following a code for the specific sequela being treated (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a past accidental tetrachloroethylene exposure.
• Verify the exposure was indeed accidental (unintentional) as per the medical record.
