Disp fx of shaft of 2nd MC bone, l hand, 7thK

This code signifies a fracture of the shaft of the second metacarpal bone in the left hand, where the bone fragments are no longer in their normal alignment. The "subsequent encounter for fracture with nonunion" indicates that the fracture has failed to heal properly after an initial treatment, and the patient is receiving ongoing care for this complication.

This code is appropriate for follow-up visits or admissions where a patient is being treated for a previously diagnosed displaced fracture of the left second metacarpal shaft that has not united. This includes scenarios involving surgical intervention for nonunion, casting changes, or evaluation of nonunion progression.

• Always confirm laterality (left hand) and the specific bone (second metacarpal shaft).
• Ensure documentation clearly states "nonunion" and that the fracture was initially displaced.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
