Nondisp fx of nk of 3rd MC bone, l hand, 7thK

This code signifies a fracture of the neck of the third metacarpal bone in the left hand that has not shifted out of alignment. The "subsequent encounter for fracture with nonunion" indicates that the bone fragments have failed to heal together after a typical healing period, and the patient is receiving ongoing care for this complication.

Use this code when a patient presents for follow-up care, treatment, or evaluation of a previously diagnosed nondisplaced fracture of the left third metacarpal neck, and the fracture has been determined to have nonunion. This applies to situations where surgical intervention for nonunion, casting, or other non-surgical management of the nonunion is being performed or monitored.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the laterality (left hand) and specific bone (third metacarpal neck) are documented.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
