Nondisp oblique fx shaft of r ulna, 7thN

This code describes a situation where a patient has a non-displaced oblique fracture in the shaft of their right ulna, which was initially an open fracture (Type IIIA, IIIB, or IIIC). The current encounter is for the management of a nonunion, meaning the fracture has failed to heal properly.

This code is used when documenting follow-up care for a patient whose right ulnar shaft fracture, originally an open injury, has not united. This includes surgical interventions, cast changes, or other treatments specifically addressing the nonunion. It signifies that the initial injury was severe, involving significant soft tissue damage.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status.
• Verify the original fracture was an open fracture type IIIA, IIIB, or IIIC.
• Do not use for initial treatment of the fracture or for routine follow-up of a healing fracture.
