Toxic effect of carbon tetrachloride, assault, sequela

This code signifies the long-term or residual effects resulting from a toxic exposure to carbon tetrachloride, specifically when the exposure was due to an intentional act of harm (assault). These sequelae can manifest as various chronic health problems affecting multiple organ systems, such as the liver, kidneys, or central nervous system, that persist after the acute phase of the poisoning has resolved.

Apply this code when documenting chronic conditions or permanent damage directly attributable to a past carbon tetrachloride poisoning that occurred as a result of an assault. This would be used for follow-up care or ongoing management of these persistent health issues, not for the initial acute poisoning event.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current condition to a past carbon tetrachloride assault.
• Do not use this code for acute toxic effects; refer to the appropriate acute poisoning codes for initial encounters.
