Displ transverse fx shaft of l ulna, 7thN

This code signifies a fracture of the shaft of the left ulna that has broken through the skin (open fracture type IIIA, IIIB, or IIIC) and is not healing properly (nonunion). The fracture is located across the bone (transverse) and the bone fragments are no longer in their normal alignment (displaced). This code is used for encounters following the initial treatment of the fracture.

Use this code when documenting ongoing care for a patient whose initial open transverse ulnar shaft fracture (left side) has failed to unite. This includes follow-up visits, surgical interventions for nonunion, or management of complications related to the nonunion in an open fracture setting.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the open fracture type (IIIA, IIIB, or IIIC) is documented, as this code is specific to these types.
• Confirm the fracture is of the "shaft" and is "transverse" and "displaced" on the "left ulna."
