Which of the following is NOT considered an external cause of injury coding?

The option pertaining to infection from a surgical procedure is not classified as an external cause of injury in coding. External cause codes are utilized to specify the circumstances under which injuries or health conditions occur, primarily involving incidents that arise from interactions with the environment, such as accidents or violence.

Infections originating from surgical procedures stem from clinical management and inherent risks associated with medical interventions rather than external mechanisms. They are more aptly categorized under healthcare-related complications and are documented using different coding conventions. Striking against another person, falls from height, and car accidents all fall under the realm of external causes as they describe events in which an individual is injured due to external factors. These types of injuries illustrate incidents that involve interactions with another person, gravity, or vehicles, thereby firmly placing them within the scope of external cause coding.
