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

This code describes a left wrist injury involving a trapezoid bone fracture that was initially nondisplaced but has subsequently healed improperly (malunion). The patient is presenting for follow-up care related to this previously treated fracture.

Apply this code for patients presenting for ongoing management of a left trapezoid fracture that has healed with malunion. This is appropriate for encounters such as physical therapy, re-evaluation, or planning for corrective surgery after the initial treatment period.

• Ensure documentation specifies "left wrist" and "trapezoid" bone.
• Confirm the fracture was initially nondisplaced and has now resulted in malunion.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
