Displ transverse fx shaft of unsp ulna, 7thH

This code signifies a fracture of the shaft of the ulna, specifically a transverse break that has shifted out of alignment. It indicates that the bone has broken through the skin (open fracture type I or II) and is not healing at the expected rate during a follow-up visit.

Apply this code during subsequent encounters for patients with an open transverse ulnar shaft fracture who are experiencing delayed union. This is used when the initial treatment has occurred, and the patient is being monitored for healing progress that is slower than anticipated.

• Ensure documentation specifies an open fracture (Type I or II) and delayed healing for this specific encounter.
• Verify the fracture location is the shaft of the ulna and the morphology is transverse.
• This code is for subsequent encounters, not the initial treatment of the fracture.
