Disp fx of prox phalanx of r thm, subs for fx w routn heal

This code signifies a fracture of the first bone in the right thumb, closest to the hand, where the bone fragments are no longer in their normal alignment. The patient is in a follow-up phase, and the fracture is progressing as expected towards full recovery.

Apply this code for follow-up visits where a patient is being monitored for a previously diagnosed displaced right thumb proximal phalanx fracture that is healing routinely. This includes appointments for cast changes, wound checks, or physical therapy evaluations during the normal healing period.

• Ensure documentation specifies "displaced" and "proximal phalanx" of the "right thumb."
• The "D" seventh character indicates a subsequent encounter for routine healing; do not use for initial treatment or delayed/nonunion.
• Verify laterality (right thumb) is clearly documented to avoid coding errors.
