Displ seg fx shaft of ulna, r arm, 7thJ

This code signifies a complex injury involving a displaced fracture that breaks the shaft of the ulna bone in the right arm into multiple segments. It specifically indicates that the skin and soft tissues were significantly damaged, exposing the bone (an open fracture of severe type), and that the fracture is not healing at the expected rate.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed severe open segmental ulnar shaft fracture of the right arm is being treated for delayed union. This includes situations where surgical intervention or other treatments are being performed to promote healing after the initial injury.

• Ensure documentation clearly specifies "right arm" and "ulna" to differentiate from other forearm fractures.
• Verify the "subsequent encounter" status and the specific "open fracture type IIIA, IIIB, or IIIC" are documented.
• Confirm that "delayed healing" is explicitly stated or clearly implied by the clinical context, such as ongoing treatment for non-union.
