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

This code signifies a fracture of the first bone of the right thumb, closest to the hand, that has shifted out of its normal alignment. The patient is in a later phase of treatment, and the fracture is not healing at the expected rate. This indicates ongoing medical management for a complication of the initial injury.

Use this code for follow-up encounters where a patient is receiving care for a displaced proximal phalanx fracture of the right thumb that is demonstrating delayed union. This applies after the initial treatment phase, such as during cast changes, follow-up X-rays, or physical therapy appointments, when the fracture is still not fully healed and healing is slower than anticipated.

• Ensure documentation clearly states "delayed healing" or similar terminology for the fracture.
• Verify the fracture is specifically of the proximal phalanx of the right thumb.
• Confirm this is a "subsequent encounter" and not the initial treatment or a sequela.
