Nondisp fx of shaft of 2nd MC bone, l hand, 7thK

This code signifies a fracture of the shaft of the second metacarpal bone in the left hand that has not healed properly, resulting in a nonunion. The fracture fragments remain in their anatomical alignment, meaning they are not displaced.

This code is used when a patient presents for follow-up care, such as cast changes, physical therapy, or surgical intervention, for a previously diagnosed nondisplaced left second metacarpal shaft fracture that has failed to unite. It indicates that the fracture is not healing as expected and requires ongoing management.

• Ensure documentation specifies "nondisplaced" and "nonunion" for the left second metacarpal shaft.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
• Always review operative reports and imaging studies to confirm fracture location, displacement, and healing status.
