Nondisp fx of neck of unsp MC bone, subs for fx w routn heal

This code describes a fracture of the neck of a metacarpal bone in the hand that is not displaced, meaning the bone fragments are still in their normal alignment. This specific code is used when the patient is receiving follow-up care for the fracture and it is healing as expected without complications.

Apply this code for patients presenting for routine follow-up appointments, such as cast changes, X-ray evaluations, or physical therapy, after an initial diagnosis of a nondisplaced metacarpal neck fracture. It is appropriate when the physician's documentation indicates the fracture is progressing through a normal healing process.

• Ensure documentation specifies "nondisplaced" and "neck" of the metacarpal.
• The 7th character "D" indicates subsequent encounter for routine healing; do not use for initial treatment or delayed/nonunion healing.
• If the specific metacarpal bone (e.g., first, second) is documented, a more specific code should be selected.
