Nondisp fx of nk of 5th MC bone, l hand, 7thP

This code indicates a fracture of the neck of the fifth metacarpal bone in the left hand that was initially nondisplaced but is now healing incorrectly. Malunion signifies that the bone fragments have united in a deformed or misaligned position, which can lead to functional impairment. This specific code is used for follow-up care related to this healing complication.

Use this code for a patient presenting for ongoing management of a previously treated left fifth metacarpal neck fracture that has healed with malunion. This applies to encounters where the malunion is being assessed, monitored, or treated, such as for physical therapy, cast changes, or surgical planning for corrective osteotomy. It should be assigned after the initial healing phase has concluded.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the fracture location is the neck of the fifth metacarpal and laterality is left hand.
• This "P" subsequent encounter code is used for active treatment of the malunion, not for routine follow-up of a healed fracture.
