Nondisp fx of shaft of 1st MC bone, unsp hand, 7thK

This code signifies a follow-up encounter for a patient experiencing a nonunion of a previously diagnosed nondisplaced fracture affecting the shaft of the first metacarpal bone. The specific hand (left or right) is not documented.

Apply this code when a patient presents for ongoing management of a first metacarpal shaft fracture that has failed to heal properly, and the fracture was initially nondisplaced. This is appropriate for subsequent visits after the initial treatment, where nonunion is the primary concern.

• Ensure documentation clearly states "nonunion" and specifies the first metacarpal shaft.
• Verify the fracture was initially nondisplaced; displaced fractures would require a different code.
• This code is for subsequent encounters, not the initial treatment of the fracture.
