Disp fx of shaft of 4th MC bone, r hand, 7thK

This code signifies a break in the shaft of the fourth metacarpal bone in the right hand that has shifted out of its normal alignment. The fracture has failed to heal properly, indicating a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

Apply this code when a patient with a previously diagnosed and treated displaced fracture of the right fourth metacarpal shaft presents for subsequent evaluation or management of a confirmed nonunion. This would include visits for continued monitoring, planning for revision surgery, or non-surgical interventions aimed at promoting healing of the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right hand and fourth metacarpal shaft.
• Verify the fracture is explicitly described as "displaced" to accurately use this specific code.
• This "K" seventh character indicates a subsequent encounter for a fracture with nonunion, so confirm the patient is not in the initial healing phase.
