Displ trimalleol fx r low leg, subs for clos fx w delay heal

This code signifies a complex fracture involving all three malleoli (medial, lateral, and posterior) of the right ankle, where the bone fragments are not properly aligned. The patient is in a later stage of recovery, and the fracture is healing slower than expected, but the skin remains intact over the fracture site.

Apply this code for follow-up encounters with patients who have previously been diagnosed and treated for a displaced trimalleolar fracture of the right lower leg. This is appropriate when the fracture is not yet fully united, and the healing process is prolonged, but there is no open wound.

• Ensure documentation specifies "right" lower leg and "displaced" nature of the fracture.
• Confirm the encounter is for "subsequent" care and that "delayed healing" is noted.
• Verify the fracture is "closed" (no open wound) to differentiate from open fracture codes.
