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

This code signifies a right wrist injury involving a non-displaced fracture of the trapezium bone, which is one of the carpal bones. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a period of time.

Apply this code when a patient presents for ongoing treatment or evaluation of a right trapezium fracture that has not healed properly. This would include scenarios such as follow-up appointments for casting, physical therapy, or surgical planning related to the nonunion.

• Ensure documentation clearly states "nonunion" for the fracture healing status.
• Verify the laterality (right wrist) and the specific bone (trapezium) are documented.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
