Toxic effect of tetrachloroethylene, accidental, subs

This code signifies an adverse health effect resulting from unintentional exposure to tetrachloroethylene, a chemical solvent. The patient is receiving follow-up care for symptoms or complications that arose from this initial toxic exposure.

Apply this code when a patient presents for ongoing treatment, monitoring, or evaluation of conditions directly attributable to an accidental tetrachloroethylene poisoning. This includes subsequent visits for organ damage, neurological sequelae, or persistent symptoms after the acute phase of exposure.

• Ensure the documentation clearly states the exposure was accidental and that this is not the initial encounter for the toxic effect.
• Always code an external cause code (e.g., from category X46) in conjunction with this code to specify the circumstances of the poisoning.
• Do not use this code for intentional self-harm or assault; different codes apply for those scenarios.
