Toxic effect of carbon tetrachloride, accidental, sequela

This code signifies the long-term or residual effects resulting from an accidental exposure to carbon tetrachloride. These sequelae can manifest in various organ systems, such as chronic liver damage, kidney dysfunction, or neurological impairments, that persist after the acute phase of poisoning has resolved.

Apply this code when documenting conditions that are a direct consequence of a past, unintentional carbon tetrachloride poisoning. This is appropriate for patients presenting with chronic health issues clearly linked to such an exposure, even if the original poisoning event occurred months or years prior.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic hepatitis, renal failure).
• Ensure documentation clearly links the current condition to a past accidental carbon tetrachloride exposure.
• Do not use this code for acute poisoning or for intentional self-harm; specific codes exist for those scenarios.
