Toxic effect of tetrachloroethylene, self-harm, sequela

This code signifies the long-term or residual effects resulting from a deliberate act of self-poisoning with tetrachloroethylene. These sequelae can manifest as chronic organ damage (e.g., liver, kidney, neurological), persistent respiratory issues, or other lasting health complications directly attributable to the initial toxic exposure.

This code is appropriate when documenting the current health status of a patient who previously attempted suicide or intentionally harmed themselves using tetrachloroethylene, and who is now presenting with chronic or residual conditions stemming from that event. It should be used after the acute phase of the poisoning has passed, and the patient is being treated for the lasting consequences.

• Always sequence this sequela code after the code(s) for the specific manifestation(s) of the sequela (e.g., chronic liver failure, persistent neuropathy).
• Ensure documentation clearly links the current condition to a past intentional tetrachloroethylene poisoning.
• Do not use this code for acute poisoning events; instead, refer to the appropriate acute toxic effect codes.
