Nondisp fx of trapezoid, left wrist, subs for fx w nonunion

This code signifies a fracture of the trapezoid bone in the left wrist that is not displaced, meaning the bone fragments remain in their anatomical position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone is failing to heal properly after a typical healing period.

This code is appropriate for documenting ongoing treatment for a left trapezoid fracture where the initial injury has already been addressed, and the current focus is on managing the complication of nonunion. This would include scenarios such as re-evaluation, further imaging, or planning for surgical intervention due to the lack of bone healing.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the fracture is specifically of the left trapezoid bone and is nondisplaced.
• Confirm this is a subsequent encounter for the fracture, not the initial treatment.
