Displ commnt fx shaft of ulna, unsp arm, 7thE

This code signifies a complex break in the middle section of the ulna bone, where the bone has shattered into multiple fragments and is no longer in its normal alignment. It specifically indicates that the skin was broken (an open fracture, type I or II) and the patient is now in a follow-up phase where the fracture is healing as expected.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed open comminuted ulnar shaft fracture (Type I or II) is being monitored for routine healing. It would be used after the initial treatment phase, such as after cast application or surgical fixation, and during routine follow-up appointments.

• Ensure documentation specifies "unspecified arm" if laterality is not clearly documented.
• Verify the fracture type (comminuted) and displacement are explicitly stated in the medical record.
• Confirm the "subsequent encounter" and "routine healing" status are clearly supported by the physician's notes.
