Displ transverse fx shaft of unsp ulna, 7thK

This code signifies a transverse fracture of the shaft of the ulna that has shifted out of alignment and is failing to heal properly. The encounter is for ongoing management of this nonunion, and the fracture is currently being treated non-surgically (closed).

This code is appropriate for follow-up visits where a patient is being treated for a previously diagnosed ulnar shaft fracture that has not united. It applies when the fracture is transverse, displaced, and the specific side (left or right) of the ulna is not documented.

• Ensure documentation specifies "nonunion" and "closed fracture" for accurate code assignment.
• Verify laterality is truly unspecified; if left or right is known, a more specific code should be used.
• This code requires an additional code for any associated external cause of the injury.
