Toxic effect of carbon tetrachloride, self-harm, sequela

This code signifies a long-term consequence or complication arising from a deliberate act of self-poisoning with carbon tetrachloride. It indicates that the acute toxic effects have resolved, but persistent health issues related to the exposure remain. These sequelae can affect various organ systems, such as the liver or kidneys.

This code is appropriate for documenting chronic conditions or permanent damage directly attributable to a past intentional carbon tetrachloride overdose. It should be used when the patient presents for treatment of these lasting effects, rather than the initial acute poisoning event. Examples include chronic liver disease or renal impairment resulting from the self-harm.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic hepatitis).
• Ensure documentation clearly links the current condition to the past intentional carbon tetrachloride exposure.
• Do not use this code for acute toxic effects; use the appropriate acute poisoning code for the initial event.
