Toxic effect of organic lead compounds

This code signifies the adverse health effects resulting from exposure to organic lead compounds. These compounds, distinct from inorganic lead, can cause a range of systemic toxicities affecting the neurological, gastrointestinal, and hematological systems. The clinical presentation often involves encephalopathy, tremors, and behavioral changes.

Use this code when documentation clearly indicates a patient's illness or injury is directly attributable to poisoning by organic lead substances. This includes occupational exposures, accidental ingestions, or intentional poisonings. Supporting documentation should detail the exposure source, symptoms, and diagnostic findings consistent with organic lead toxicity.

• Differentiate carefully between organic and inorganic lead poisoning; this code is specific to organic compounds.
• Always code the specific manifestation(s) of the toxicity first, then use this code as an external cause code to identify the substance.
• Ensure documentation specifies the type of lead compound (e.g., tetraethyl lead, tetramethyl lead) if known, to support the "organic" distinction.
