Toxic effect of chloroform, accidental, sequela

This code signifies a long-term or residual condition resulting from an accidental exposure to chloroform. It indicates that the acute toxic effects have resolved, but the patient is experiencing persistent health problems directly attributable to that past poisoning event. These sequelae can manifest in various organ systems, depending on the severity and duration of the original exposure.

Apply this code when documenting a patient presenting with chronic health issues, such as neurological deficits, liver damage, or renal impairment, that are definitively linked to a prior unintentional chloroform poisoning. This code is appropriate for follow-up encounters occurring after the initial acute phase of the toxic event has passed. It should be used when the primary reason for the encounter is the management of these lasting effects.

• Always sequence this sequela code after the code(s) identifying the specific nature of the sequela (e.g., chronic hepatitis, peripheral neuropathy).
• Ensure documentation clearly establishes the causal link between the past accidental chloroform exposure and the current chronic condition.
• Do not use this code for acute toxic effects; refer to the appropriate acute poisoning codes for initial and subsequent encounters during the active phase of toxicity.
