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

This code signifies a fracture of the trapezoid bone in the wrist that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. The "subsequent encounter" indicates that this is not the initial treatment for the fracture, and "malunion" specifies that the bone has healed incorrectly, resulting in an anatomical deformity. The "unspecified wrist" denotes that the laterality (left or right) of the wrist is not documented.

Use this code when a patient presents for follow-up care of a trapezoid fracture that has healed in a misaligned position, and the initial treatment has already occurred. This would apply to situations where the malunion is being assessed, monitored, or treated in a subsequent visit.

• Ensure documentation clearly states "malunion" and "subsequent encounter" for this specific fracture.
• Verify that the fracture is indeed of the trapezoid bone and not another carpal bone.
• If the laterality (left or right wrist) is documented, a more specific code should be selected.
