Displ oblique fx shaft of r ulna, 7thR

This code describes a situation where a patient has a displaced oblique fracture of the shaft of their right ulna, and they are being seen for follow-up care related to an open fracture (Type IIIA, IIIB, or IIIC) that has healed incorrectly (malunion). This indicates a complication in the healing process of a severe open ulnar fracture.

Use this code for subsequent encounters when a patient presents with a previously diagnosed displaced oblique fracture of the right ulnar shaft, which was initially an open fracture (Type IIIA, IIIB, or IIIC), and the current clinical assessment confirms a malunion. This code is appropriate for ongoing management, evaluation of the malunion, or planning for corrective procedures.

• Ensure documentation clearly specifies "malunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify laterality (right ulna) is explicitly stated in the medical record.
• This code is for subsequent encounters, not the initial treatment of the fracture.
