This division classifies traumatic injuries and disorders, acute effects of external agents, and acute poisoning and toxic effects. Generally, a traumatic injury or disorder is the result of a single incident, event, or exposure over the course of a single shift. Cases coded to this division need not be consistent with the Occupational Safety and Health Administration (OSHA) recordkeeping definition of an injury or whether the employer reported the case as an injury or illness on the OSHA log.

This division classifies toxic and non-toxic diseases or disorders affecting systems of the body. Diseases or disorders included may affect the whole named body system, or more commonly, affect only a part of the named body systems at the time of diagnosis.

This division classifies five types of infections: bacterial, viral, rickettsial, fungal, and parasitic infections. These infectious agents are transmitted to a person through inhalation, ingestion, or contact with the skin. These diseases are generally recognized as communicable or transmissible, with a few of unknown but possibly infectious origin.

This division classifies diseases or conditions related to tumors, or neoplasms: the new growth of tissue in which the multiplication of cells is uncontrolled and progressive. The behavior of tumors or neoplasms may be benign, cancerous, or of uncertain behavior at the time of diagnosis.

This division classifies symptoms, signs, or abnormal results from laboratory or investigative medical tests or procedures. It includes those ill-defined conditions that cannot be classified elsewhere. Codes from this division should be used when no specific diagnosis is named and cannot be inferred from information found on the source document. This division includes sick building syndrome. Symptoms and ill-defined conditions resulting from traumatic incidents or exposures are classified in Division 1.

This division classifies physical characteristics for which there is sufficient information for coding purposes, but no specific code exists in previous divisions of the nature of injury or illness structure.
