Disp fx of nk of 1st MC bone, unsp hand, 7thG

This code signifies a break in the neck of the first metacarpal bone (thumb) that has shifted out of alignment. It is used when the patient is presenting for follow-up care, and the fracture is not healing at the expected rate. The specific hand affected is not documented.

Apply this code for a patient returning for an office visit, cast change, or other follow-up care for a displaced first metacarpal neck fracture where the physician notes delayed healing. This would be used after the initial treatment phase and before definitive healing has occurred.

• Ensure documentation clearly states "delayed healing" for this specific fracture.
• Verify the fracture is indeed of the "neck" of the first metacarpal and is "displaced."
• Confirm this is a "subsequent encounter" and not the initial treatment.
