Nondisp fx of nk of 4th MC bone, r hand, 7thP

This code describes a situation where a patient has a fracture in the neck of the fourth metacarpal bone in their right hand that was not displaced at the time of injury. The fracture has healed, but with an imperfect alignment (malunion), and the patient is presenting for follow-up care related to this malunion.

Use this code for a patient presenting for ongoing management or evaluation of a previously treated, nondisplaced fracture of the right fourth metacarpal neck that has resulted in malunion. This would apply to encounters where the focus is on assessing the functional impact of the malunion, planning corrective procedures, or monitoring its stability.

• Ensure documentation clearly states "malunion" and specifies the "subsequent encounter" for the fracture.
• Verify the fracture was originally nondisplaced and located in the neck of the fourth metacarpal of the right hand.
• Do not use this code for initial treatment of the fracture or for nonunion; specific codes exist for those scenarios.
