Toxic effect of chlorinated hydrocarbons

This code signifies the adverse health effects resulting from exposure to and absorption of chlorinated hydrocarbon compounds. These substances, often found in solvents, pesticides, and refrigerants, can cause a range of systemic toxicities affecting the central nervous system, liver, kidneys, and cardiovascular system. The clinical presentation varies based on the specific compound, dose, and route of exposure.

Use this code when documentation clearly indicates a patient's signs and symptoms are due to the toxic effects of chlorinated hydrocarbons, such as acute poisoning from ingestion, inhalation, or dermal absorption. This applies to both accidental and intentional exposures. Supporting documentation should include a history of exposure, clinical findings consistent with chlorinated hydrocarbon toxicity, and potentially laboratory confirmation of exposure or organ damage.

• Always sequence this code as the primary diagnosis when it represents the acute poisoning event.
• Code any specific manifestations or organ damage (e.g., toxic hepatitis, acute renal failure, encephalopathy) as secondary diagnoses.
• Distinguish from adverse effects of therapeutic drugs, which are coded differently. Ensure the documentation specifies exposure to a non-medicinal chlorinated hydrocarbon.
