Disp fx of base of unsp MC bone, subs for fx w routn heal

This code signifies a fracture at the base of an unspecified metacarpal bone that was initially displaced but is now in the routine healing phase. It indicates that the patient is returning for follow-up care, and the fracture is progressing as expected without complications.

Apply this code for follow-up visits where a patient is being monitored for a previously diagnosed displaced metacarpal base fracture, and the physician documents routine healing. This is appropriate when the fracture is stable and no further acute intervention is required.

• Ensure documentation specifies "displaced" and "base of metacarpal" for accurate coding.
• The "D" seventh character indicates a subsequent encounter for routine healing, not initial treatment or delayed healing.
• Confirm that the specific metacarpal bone is not identified in the documentation; otherwise, a more specific code would be appropriate.
