Displ transverse fx shaft of l ulna, 7thP

This code signifies a fracture of the mid-portion of the left ulna that has healed improperly, resulting in a malunion. The fracture was initially displaced, meaning the bone fragments were not aligned. This code is used for follow-up care after the initial treatment of the fracture.

Apply this code when a patient presents for ongoing management or evaluation of a previously treated left ulnar shaft fracture that has healed in an unsatisfactory position. This includes scenarios where the malunion is causing functional impairment or pain, or when further intervention is being considered.

• Ensure documentation clearly specifies "left ulna" and "shaft" for accurate laterality and location.
• The "P" seventh character indicates a subsequent encounter for a closed fracture with malunion, so verify the encounter type.
• Differentiate from nonunion (S52.222N) where the fracture has not healed at all.
