Oth fx upr end r ulna, 7thR

This code signifies a malunion of an open fracture (Gustilo type IIIA, IIIB, or IIIC) of the proximal right ulna, excluding the olecranon or coronoid process. It indicates that the fracture has healed in a misaligned position, requiring ongoing management.

Apply this code for patients presenting with a documented malunion of a previously treated severe open fracture of the upper right ulna (excluding specific processes). This is appropriate for follow-up visits where the malunion is being assessed or managed, such as for pain, functional limitation, or planning for corrective surgery.

• Ensure documentation specifies "malunion" and not "nonunion" or "delayed union."
• Verify the fracture location is the "upper end of ulna" and not the olecranon or coronoid process, which have specific codes.
• Confirm the original fracture was an open fracture of Gustilo type IIIA, IIIB, or IIIC.
