989.4
ICD-9-CMThis code signifies adverse health effects resulting from exposure to pesticides not specifically categorized elsewhere. It covers systemic or localized reactions to various chemical agents used for pest control, excluding those with dedicated ICD-9-CM codes. The effects can range from acute poisoning symptoms to chronic health issues.
Use this code when documentation clearly indicates a patient's illness or injury is directly attributable to contact with an unspecified pesticide. This includes accidental ingestion, inhalation, or dermal absorption. Supporting documentation should specify the type of pesticide if known, but if not, and it's not one with a more specific code, this code is appropriate.
