Disp fx of l ulna styloid pro, 7thR

This code signifies a malunion of a displaced fracture involving the styloid process of the left ulna. It specifically applies to a subsequent encounter where the initial injury was an open fracture classified as Type IIIA, IIIB, or IIIC. Malunion indicates that the bone has healed in an incorrect anatomical position.

Apply this code when documenting follow-up care for a patient who previously sustained a severe open fracture of the left ulnar styloid and has now developed a malunion. This would be used in settings such as orthopedic clinics, physical therapy, or during re-evaluation for potential corrective surgery. It is crucial that the original fracture was an open Type IIIA, IIIB, or IIIC.

• Ensure documentation clearly specifies "malunion" and the left side.
• Verify the original fracture was an open Type IIIA, IIIB, or IIIC, as this is a specific inclusion criterion.
• Do not use for nonunion, delayed union, or initial encounter for the fracture.
