Displ transverse fx shaft of l ulna, 7thQ

This code signifies a specific type of healing complication: a malunion of a displaced transverse fracture in the shaft of the left ulna. It indicates that the bone has healed, but in an anatomically incorrect position, following an initial open fracture (Type I or II). This is a subsequent encounter, meaning the patient is returning for care related to this malunion.

Use this code for follow-up encounters where a patient presents with a confirmed malunion of a previously treated open transverse fracture of the left ulnar shaft. This would apply when the malunion is documented as displaced and the initial injury was an open fracture type I or II. This code is appropriate when the malunion itself is the focus of the current encounter, such as for evaluation, planning for corrective surgery, or ongoing management.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the fracture location is the shaft of the left ulna and the original injury was an open fracture type I or II.
• Confirm this is a subsequent encounter for the malunion, not the initial treatment of the fracture.
