Nondisp oblique fx shaft of unsp ulna, 7thP

This code signifies a follow-up encounter for a previously diagnosed oblique fracture of the ulnar shaft, where the bone fragments are no longer in their anatomical alignment (malunion) and the skin over the fracture site remains intact. The specific ulna (left or right) was not documented at the time of the initial diagnosis.

This code is appropriate for subsequent visits when a patient is being managed for a closed, nondisplaced oblique ulnar shaft fracture that has healed in a misaligned position. This includes scenarios such as monitoring the malunion, planning for corrective surgery, or assessing functional limitations due to the malunion.

• Ensure documentation clearly states "malunion" and specifies a "subsequent encounter" for a closed fracture.
• Verify the fracture type is "oblique" and located on the "shaft" of the ulna.
• If the laterality of the ulna is documented, a more specific code should be selected.
