Toxic effect of carbon tetrachloride

This code represents the adverse health effects resulting from exposure to carbon tetrachloride, a potent hepatotoxin and nephrotoxin. It encompasses systemic toxicity, organ damage (particularly liver and kidney), and neurological symptoms caused by ingestion, inhalation, or dermal absorption of this chemical.

Use this code when documentation clearly indicates a patient's signs, symptoms, or diagnosed conditions are directly attributable to carbon tetrachloride poisoning. This includes cases of accidental exposure, occupational exposure, or intentional ingestion. Supporting documentation should specify the substance as carbon tetrachloride and link it to the patient's clinical presentation.

• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
• Do not confuse this with codes for toxic effects of other halogenated hydrocarbons; specificity is key.
• Look for documentation of the specific route of exposure (e.g., inhalation, ingestion) as this may influence other associated codes.
