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

This code signifies a fracture of the thumb's proximal phalanx, where the bone fragments are no longer in their normal alignment. It indicates that the patient is in a subsequent phase of care for this injury, and the fracture is healing as expected without complications.

Apply this code when documenting follow-up care for a patient with a previously diagnosed displaced fracture of the thumb's proximal phalanx. This is appropriate when the physician assesses the fracture and confirms routine healing, such as during cast changes, follow-up X-rays showing callus formation, or physical therapy sessions for a healing fracture.

• Ensure documentation specifies "displaced" and "proximal phalanx of thumb" for accurate code selection.
• The "D" seventh character indicates a subsequent encounter with routine healing; do not use for initial treatment or delayed/nonunion healing.
• Confirm the laterality (left, right, or unspecified) is clearly documented; this code is for an unspecified thumb.
