Nondisp seg fx shaft of ulna, l arm, 7thP

This code describes a fracture in the middle section of the ulna bone in the left forearm that has not shifted out of alignment. The fracture is in a healing phase, but the bone is mending in an abnormal position, indicating a malunion.

Apply this code when a patient presents for follow-up care of a previously diagnosed left ulnar shaft fracture that is now demonstrating malunion. This code is appropriate for subsequent encounters where the fracture is still closed and the malunion is being managed.

• Ensure documentation clearly specifies "left arm" and "ulna" for laterality and bone.
• Verify the encounter is for a "subsequent encounter" and the fracture is "closed" with evidence of "malunion."
• Do not use for initial encounters or for open fractures.
