Disp fx of l ulna styloid pro, subs for clos fx w malunion

This code signifies a left ulna styloid process fracture that was initially displaced but has since healed in an imperfect alignment (malunion). The fracture is currently closed, meaning the skin over the injury is intact. This code is used when the patient is receiving follow-up care for this specific complication.

Apply this code when a patient presents for ongoing management of a previously treated left ulna styloid fracture that has healed with malunion. This could include evaluations for pain, functional limitations, or consideration of corrective procedures related to the malunion. It is appropriate for any encounter after the initial treatment phase, where the malunion is the focus of care.

• Ensure documentation clearly states "malunion" and specifies the left ulna styloid process.
• Verify that the encounter is for follow-up care, not the initial treatment or routine healing.
• Always check for laterality (left vs. right) and the specific bone/process involved.
