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

This code indicates a fracture of the proximal phalanx of the left thumb that is no longer in its anatomical position, and the patient is presenting for follow-up care during the normal healing period. The displacement has been addressed, and the bone is now healing as expected.

This code is appropriate for follow-up visits after initial treatment of a displaced left thumb proximal phalanx fracture, such as cast changes, physical therapy evaluations, or routine radiographic checks, as long as the fracture is progressing with routine healing. It should be used when the patient is past the initial acute treatment phase but not yet fully recovered.

• Ensure documentation specifies "left thumb" and "proximal phalanx" to differentiate from other hand fractures.
• Verify the fracture is explicitly documented as "displaced" and that healing is described as "routine" or "expected."
• Do not use this code if the fracture is nonunion, malunion, or experiencing delayed healing; different codes apply for those complications.
