Disp fx of base of 5th MC bone, r hand, 7thP

This code signifies a right hand injury involving a break at the base of the fifth metacarpal bone that has healed improperly, resulting in a malunion. The fracture was initially displaced, meaning the bone fragments were not in their normal alignment. This specific code indicates that the patient is in a subsequent phase of care for this malunited fracture.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed and now malunited displaced fracture of the right fifth metacarpal base. This includes visits for assessing the malunion, planning for corrective surgery, or managing ongoing symptoms related to the improper healing. It should be used when the fracture is no longer in the initial healing phase but has consolidated in an unsatisfactory position.

• Ensure documentation clearly states "malunion" and specifies the right hand and base of the fifth metacarpal.
• Verify that the encounter is for follow-up care of the malunion, not the initial treatment or routine healing.
• Pair with external cause codes (V, W, X, Y) if the cause of the original fracture is relevant and documented.
