Toxic effect of carbon tetrachloride, accidental, subs

This code signifies a toxic reaction to carbon tetrachloride due to an accidental exposure, specifically during a subsequent encounter for care. This means the patient is receiving follow-up treatment or monitoring for the lingering effects or complications of the initial unintentional poisoning.

Apply this code when a patient presents for ongoing management of symptoms, complications, or sequelae stemming from an accidental carbon tetrachloride poisoning. This includes visits for continued detoxification, organ support, or addressing long-term damage to the liver, kidneys, or central nervous system after the initial acute phase.

• Ensure documentation clearly states "accidental" or "unintentional" exposure to carbon tetrachloride.
• Confirm the encounter is for follow-up care, not the initial treatment of the acute poisoning.
• Always code additional diagnoses for specific manifestations or complications of the toxicity (e.g., acute kidney failure, toxic hepatitis).
