Nondisp trimalleol fx r low leg, 7thN

This code describes a complex fracture involving all three malleoli (medial, lateral, and posterior) of the right lower leg, which is currently not aligned. It specifically indicates that the initial injury was an open fracture of severe type (IIIA, IIIB, or IIIC) and that the bone fragments have failed to heal properly over time, resulting in a nonunion.

This code is appropriate for documenting follow-up care for a patient with a previously treated trimalleolar fracture of the right lower leg that was initially open and severe, and where imaging or clinical assessment confirms that the fracture has not united. It would be used for encounters related to ongoing management of the nonunion, such as surgical planning for revision fixation or continued conservative management.

• Ensure documentation clearly specifies "nondisplaced" and "right lower leg" for accurate laterality and displacement.
• Verify that the initial injury was indeed an open fracture type IIIA, IIIB, or IIIC and that nonunion is explicitly documented.
• This code is for subsequent encounters; an initial encounter for this specific fracture with nonunion would use a different code.
