Nondisp transverse fx shaft of r ulna, 7thM

This code signifies a transverse fracture of the shaft of the right ulna that has not displaced, meaning the bone fragments are still in their normal alignment. It specifically indicates that this is a subsequent encounter for an open fracture (where the bone broke through the skin) classified as Type I or Type II, and that the fracture has failed to heal properly (nonunion).

Apply this code when a patient presents for follow-up care of a previously diagnosed open transverse ulnar shaft fracture (Type I or II) on the right side, and imaging or clinical assessment confirms that the fracture has not united. This would be used for ongoing management of the nonunion, such as planning for revision surgery or monitoring healing progress.

• Ensure documentation clearly specifies "nonunion" for the right ulnar shaft fracture.
• Verify the original fracture was indeed an open fracture, Type I or II, and that this is a subsequent encounter.
• Do not use for initial encounters or for closed fractures.
