Nondisp fx of trapezium, right wrist, subs for fx w malunion

This code indicates a fracture of the trapezium bone in the right wrist that is not displaced, meaning the bone fragments are still in their normal alignment. The "subsequent encounter" aspect signifies that the patient is receiving follow-up care for this fracture, and "malunion" specifies that the fracture is healing in an unsatisfactory position, leading to functional impairment.

Use this code for a patient presenting for ongoing treatment of a right trapezium fracture that has healed incorrectly or is in the process of healing incorrectly. This would apply when a physician documents malunion of the fracture during a follow-up visit, such as for cast changes, physical therapy, or surgical planning to correct the malunion.

• Ensure documentation clearly specifies "right wrist" and "trapezium" (or "larger multangular").
• Verify the encounter is for subsequent care and that malunion is explicitly documented.
• Do not use if the fracture is displaced, involves a different bone, or is an initial encounter.
