Displ seg fx shaft of ulna, unsp arm, 7thC

This code signifies a severe break in the middle section of the ulna bone, which is one of the two long bones in the forearm. The fracture is "segmental," meaning there are at least two fracture lines creating a free segment of bone, and "displaced," indicating the bone fragments are not properly aligned. It also specifies an open fracture of Type IIIA, IIIB, or IIIC, meaning the skin and soft tissues are significantly damaged, exposing the bone, and requiring immediate surgical intervention.

Apply this code for a patient presenting with an initial injury involving a complex, open fracture of the ulnar shaft that meets the criteria for Gustilo-Anderson Type IIIA, IIIB, or IIIC. This typically occurs due to high-energy trauma, such as a motor vehicle accident or a significant fall. This code is used during the initial treatment phase of the injury.

• Ensure documentation clearly specifies "segmental" and "displaced" for the ulnar shaft fracture.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated by the physician.
• Confirm this is the patient's initial encounter for this specific injury; subsequent care would use a different encounter character.
