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

This code signifies a fracture located in the shaft of the third metacarpal bone in the left hand, which has become displaced. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is appropriate for patients presenting for subsequent treatment of a previously diagnosed and treated displaced fracture of the left third metacarpal shaft that has developed a nonunion. This includes scenarios such as surgical intervention for nonunion, casting changes, or evaluation of healing progress for a nonunion.

• Ensure documentation clearly specifies "nonunion" and "subsequent encounter" for this specific fracture.
• Verify the laterality (left hand) and the specific metacarpal bone (third) are accurately documented.
• Do not use this code for initial fracture treatment or for malunion, which is a different complication.
