Toxic effect of tetrachloroethylene, assault, subs encntr

This code signifies a harmful reaction to tetrachloroethylene, a chemical often used as a solvent, when the exposure is intentionally inflicted by another person with the intent to cause harm. The "subsequent encounter" indicates that the patient is receiving follow-up care for the toxic effects after the initial treatment of the acute poisoning.

Use this code for patients presenting for ongoing management, monitoring, or treatment of symptoms and complications arising from tetrachloroethylene poisoning that was the result of an assault. This includes follow-up appointments for organ damage, neurological effects, or other chronic issues stemming from the initial toxic exposure.

• Ensure documentation clearly states the toxic effect is due to tetrachloroethylene and was an assault.
• Confirm the encounter is for follow-up care, not the initial acute treatment.
• Do not use this code for accidental or intentional self-harm exposures; specific codes exist for those circumstances.
