Open fracture of sternum

This code signifies a traumatic break in the sternum (breastbone) where the skin and underlying soft tissues are also compromised, exposing the fracture site to the external environment. This type of injury carries a higher risk of infection compared to a closed fracture due to the direct communication with the outside.

Apply this code when documentation explicitly states an "open" or "compound" fracture of the sternum. This typically occurs following high-impact trauma such as motor vehicle accidents or direct blows to the chest. Physician notes must clearly describe the open nature of the wound in conjunction with the sternal fracture.

• Differentiate carefully between "open" and "closed" sternal fractures; the presence of an open wound communicating with the fracture is key.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Look for associated external cause of injury codes (E-codes) to provide a complete picture of the trauma.
