Displ commnt fx shaft of ulna, r arm, 7thQ

This code signifies a complex fracture involving the shaft of the right ulna, where the bone is broken into multiple fragments and the pieces are not in their normal alignment. It specifically indicates that this is a follow-up encounter for an open fracture (where the skin was broken) that has healed in an imperfect position, resulting in malunion.

This code is appropriate for subsequent encounters when a patient presents with a previously treated open comminuted fracture of the right ulnar shaft (Type I or II) that has now developed malunion. This would typically be used during follow-up appointments where the malunion is being assessed or managed, after the initial healing phase.

• Ensure documentation clearly specifies "right arm" and "ulna shaft" to differentiate from radius or other arm bones.
• Verify the "subsequent encounter" status and the presence of "malunion" in the physician's notes.
• Confirm the original fracture was an "open fracture type I or II" as this impacts code selection.
