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

This code signifies a right ulna styloid process fracture that has healed incorrectly, resulting in a malunion. The fracture was initially displaced, and the current encounter is for follow-up care or management of this improperly healed bone.

Apply this code when a patient presents for evaluation or treatment of a right ulna styloid fracture that has previously been treated but has healed in an anatomically incorrect position. This is used for subsequent visits after the initial treatment, where the malunion is the focus of the encounter.

• Ensure documentation clearly states "malunion" and specifies the right ulna styloid process.
• Verify the encounter is "subsequent" and not the initial treatment for the fracture.
• Confirm the fracture was "closed" and "displaced" at the time of injury.
