Nondisp spiral fx shaft of ulna, unsp arm, 7thC

This code signifies a fracture of the ulna's shaft that follows a spiral pattern, meaning the fracture line twists around the bone. The bone fragments remain in their normal anatomical alignment (nondisplaced), and the injury involves an open wound exposing the bone, classified as a severe Type IIIA, IIIB, or IIIC open fracture. This specific code is used for the initial treatment of such an injury when the affected arm is not specified.

This code is appropriate for documenting the initial encounter for a patient presenting with a newly diagnosed, nondisplaced spiral fracture of the ulnar shaft. It is specifically used when the fracture is open and categorized as Gustilo-Anderson Type IIIA, IIIB, or IIIC, and the laterality of the arm (left or right) is not documented.

• Ensure the documentation explicitly states "nondisplaced" and "spiral fracture of shaft of ulna."
• Verify that the open fracture is classified as Type IIIA, IIIB, or IIIC and that this is the initial treatment encounter.
• Only use this code when the medical record does not specify whether the fracture is on the left or right arm. If laterality is known, a more specific code should be used.
