Displ trimalleol fx l low leg, 7thJ

This code signifies a complex fracture involving all three malleoli (medial, lateral, and posterior) of the left lower leg, where the bone fragments are not properly aligned. It specifically describes a subsequent encounter for an open fracture (meaning the skin was broken) that was initially classified as Type IIIA, IIIB, or IIIC, and is now experiencing delayed healing.

Use this code for patients presenting for follow-up care of a previously treated displaced trimalleolar fracture of the left lower leg that was an open fracture (Type IIIA, IIIB, or IIIC) and is not healing within the expected timeframe. This applies when the patient is still receiving active treatment for the delayed healing, such as cast changes, wound care, or surgical intervention to promote union.

• Ensure documentation clearly specifies "displaced" and "trimalleolar" for the left lower leg.
• Confirm the encounter is "subsequent" and that delayed healing of an "open fracture type IIIA, IIIB, or IIIC" is explicitly documented.
• Do not use this code for initial encounters or for fractures that are healing normally.
