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

This code signifies a follow-up visit for a break in the long part of the first metacarpal bone (thumb bone) that is healing normally. The bone fragments remain in their correct anatomical position, and the specific hand affected is not documented.

This code is appropriate for subsequent encounters where a patient is receiving ongoing care for a previously diagnosed, nondisplaced first metacarpal shaft fracture. It indicates routine healing without complications, such as malunion or nonunion. This would be used for cast changes, follow-up X-rays showing expected callus formation, or routine wound checks.

• Ensure documentation specifies "subsequent encounter" and "routine healing."
• Verify the fracture is indeed of the shaft and not the base or head of the metacarpal.
• If the hand is specified (left or right), a more specific code should be used.
