Disp fx of distal phalanx of thmb, subs for fx w routn heal

This code signifies a fracture of the furthest bone in the thumb, where the broken pieces are no longer in their correct anatomical alignment. The patient is in a follow-up phase of care, and the fracture is progressing as expected toward full recovery without complications.

Apply this code when documenting a subsequent visit for a patient with a previously diagnosed displaced fracture of the distal phalanx of the thumb, and the physician notes routine healing. This would typically be used during cast changes, follow-up X-rays showing callus formation, or routine check-ups during the healing period.

• Ensure documentation specifies "displaced" and "distal phalanx of thumb" for accurate selection.
• The "D" seventh character indicates a subsequent encounter for routine healing; do not use for initial treatment or delayed/nonunion.
• Verify laterality (left, right, or unspecified) is consistent with the patient's record.
