Disp fx of neck of metacarpal bone, subs for fx w routn heal

This code signifies a fracture of the neck of a metacarpal bone, excluding the thumb, where the bone fragments are no longer in their normal alignment. This specific code is used when the patient is seen for follow-up care during the routine healing phase of the fracture.

This code is appropriate for subsequent encounters where a patient is being monitored for a displaced fracture of the 2nd, 3rd, 4th, or 5th metacarpal neck that is healing as expected. Examples include follow-up appointments for cast checks, X-ray evaluations confirming routine callus formation, or physical therapy sessions during the uncomplicated recovery period.

• Ensure documentation specifies "displaced" and "neck of other metacarpal" (i.e., not the thumb).
• The 7th character "D" indicates a subsequent encounter for routine healing; use "A" for initial treatment or "G" for delayed healing.
• Always verify the specific metacarpal involved if documented, though this code covers "other" (2-5).
