Displ oblique fx shaft of r ulna, 7thQ

This code describes a specific type of fracture involving the shaft of the right ulna, characterized by an oblique break that is displaced. The fracture was initially an open fracture of either Type I or Type II, and the current encounter is for treatment of a malunion, meaning the bone has healed in an incorrect anatomical position.

Use this code for follow-up encounters where a patient is being treated for a malunion of a previously sustained displaced oblique fracture of the right ulnar shaft. The initial injury must have been classified as an open fracture (Type I or II). This code is appropriate when the malunion is the primary focus of the current treatment.

• Ensure documentation clearly specifies "malunion" and not nonunion or delayed union.
• Verify the initial fracture was an open fracture (Type I or II) and involved the shaft of the right ulna.
• Confirm the fracture morphology is "oblique" and "displaced."
