Closed fracture of sternum

This code signifies a complete or incomplete break in the sternum (breastbone) where the skin and underlying soft tissues remain intact, without an open wound communicating with the fracture site. It represents a non-displaced or displaced fracture that has not penetrated the skin.

Apply this code when documentation clearly indicates a sternal fracture without an associated open wound. This typically occurs following blunt force trauma to the chest, such as from motor vehicle accidents or direct impact. Supporting documentation includes imaging reports (e.g., X-ray, CT scan) confirming the fracture and physician notes specifying "closed" or "intact skin."

• Differentiate from open fractures of the sternum, which involve a break in the skin and require different coding.
• Ensure the documentation specifies "closed" to avoid miscoding with open fracture codes.
• Sequence this code as the primary diagnosis if it is the reason for the encounter, followed by codes for any associated injuries.
