Displ transverse fx shaft of unsp ulna, 7thC

This code signifies a break across the shaft of the ulna, where the bone fragments are no longer in their normal alignment. The fracture is open, meaning the bone has broken through the skin, and is classified as a severe open fracture (Type IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification. This code is used for the initial treatment of such an injury when the specific ulna (left or right) is not documented.

This code is appropriate for documenting the initial encounter for a patient presenting with a displaced, open transverse fracture of the ulnar shaft. It should be selected when the medical record clearly indicates an open fracture of Gustilo-Anderson Type IIIA, IIIB, or IIIC, but does not specify whether it's the left or right ulna. This code is used for the acute phase of treatment, including surgical repair or initial stabilization.

• Ensure documentation specifies "displaced" and "transverse" for the fracture type.
• Verify the Gustilo-Anderson classification (Type IIIA, IIIB, or IIIC) is clearly stated for the open fracture.
• Only use this code when the laterality (left or right ulna) is not documented; otherwise, a more specific code should be chosen.
