Toxic effect of inorganic lead compounds

This code signifies the adverse health effects resulting from exposure to and absorption of inorganic lead compounds. It encompasses the systemic toxicity caused by lead, which can manifest in various organ systems including neurological, gastrointestinal, and hematological. This diagnosis indicates a direct causal link between inorganic lead exposure and the patient's presenting symptoms or conditions.

Use this code when documentation clearly indicates a patient's illness or symptoms are directly attributable to exposure to inorganic lead. This typically applies to cases of lead poisoning, whether acute or chronic, confirmed by elevated blood lead levels and clinical signs of toxicity. Supporting documentation should include laboratory results, exposure history, and a physician's assessment linking the exposure to the patient's condition.

• Differentiate from organic lead compound toxicity (e.g., tetraethyl lead), which is coded elsewhere.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
• Look for specific documentation of the source of lead exposure (e.g., paint, industrial fumes) to potentially add an E-code for external cause.
