Disp fx of shaft of 3rd MC bone, l hand, 7thP

This code signifies a left-hand injury involving a break in the shaft of the third metacarpal bone, which has shifted out of its normal alignment. The patient is currently receiving care for this fracture, and it is healing improperly, resulting in a malunion.

Apply this code when documenting follow-up care for a patient with a previously diagnosed displaced fracture of the left third metacarpal shaft, where the bone fragments have healed in an anatomically incorrect position. This would be used for encounters addressing the complications of this malunion, such as pain, deformity, or functional limitations.

• Ensure documentation clearly specifies "left hand" and "third metacarpal."
• Verify that the encounter is for a "subsequent encounter" and that "malunion" is explicitly stated or clearly implied by the clinical context.
• Distinguish from nonunion (failure to heal) or routine follow-up without malunion.
