Disp fx of nk of 5th MC bone, l hand, subs for fx w malunion

This code signifies a fracture in the neck of the fifth metacarpal bone (pinky finger) in the left hand, where the bone fragments are not properly aligned. It specifically indicates that the patient is in a later stage of healing where the fracture has healed, but with an unsatisfactory alignment (malunion).

This code is appropriate for follow-up encounters when a patient with a previously diagnosed displaced fracture of the left fifth metacarpal neck presents with evidence of malunion. This could include imaging studies confirming improper healing or clinical signs related to the malaligned bone. It should be used when the primary treatment for the fracture has concluded, and the focus is now on managing the consequences of the malunion.

• Always confirm the laterality (left hand) and the specific bone (fifth metacarpal neck).
• Verify documentation explicitly states "malunion" and that the encounter is for follow-up care related to this complication.
• Do not use this code for initial treatment or routine follow-up of a healing fracture without malunion.
