Displ bimalleol fx unsp low leg, 7thM

This code signifies a bimalleolar fracture of the lower leg where both the medial and lateral malleoli are broken and the bone fragments are not properly aligned. This specific code is used when the patient is receiving follow-up care for a previously treated open fracture (Gustilo-Anderson type I or II) that has failed to heal properly, resulting in a nonunion.

Use this code for a patient presenting for ongoing management of a bimalleolar fracture that was initially an open fracture and is now complicated by nonunion. This applies to subsequent visits after the initial treatment, such as for surgical intervention to promote healing or for continued monitoring of the nonunion.

• Requires a documented history of an open bimalleolar fracture (Type I or II) and current nonunion.
• "Subsequent encounter" indicates care after the initial treatment phase, including routine follow-up or treatment for complications.
• Ensure laterality (left/right) is specified if known; "unspecified" should only be used when documentation lacks this detail.
