Disp fx of r ulna styloid pro, 7thQ

This code signifies a malunion of a previously sustained displaced fracture of the styloid process of the right ulna. The original injury was an open fracture, classified as either Type I or Type II, indicating a break in the skin with minimal to moderate soft tissue damage.

This code is appropriate for follow-up encounters where a patient is being treated for complications arising from the improper healing (malunion) of a right ulnar styloid open fracture (Type I or II). This would include evaluations for pain, limited range of motion, or other functional impairments directly attributable to the malunion.

• Requires an external cause code (V00-Y99) to describe the circumstances of the original injury.
• Always sequence this code after the primary diagnosis for the current encounter, if applicable.
• Ensure documentation clearly specifies "malunion" and the original open fracture type (I or II) for the right ulna styloid.
