Toxic effect of other chlorinated hydrocarbon solvents

This code describes the adverse health effects resulting from exposure to chlorinated hydrocarbon solvents other than those specifically classified elsewhere. These toxic effects can manifest as acute or chronic organ damage, neurological symptoms, or systemic illness due to absorption, inhalation, or ingestion of these chemicals.

Use this code when documentation clearly indicates a patient's illness or injury is directly attributable to poisoning or adverse reaction from exposure to chlorinated hydrocarbon solvents (e.g., trichloroethylene, perchloroethylene, carbon tetrachloride). This applies to accidental exposure, intentional self-harm, or therapeutic misadventure. Documentation should specify the type of solvent if known, and the resulting clinical manifestations.

• Always sequence this code as a primary diagnosis when it represents the principal reason for the encounter.
• Code any specific clinical manifestations (e.g., toxic hepatitis, renal failure) as secondary diagnoses.
• Differentiate from poisoning by other types of solvents (e.g., petroleum-based solvents) which have different ICD-9-CM codes.
