Displ Maisonneuve's fx unsp leg, 7thJ

This code describes a Maisonneuve's fracture, which is a specific type of ankle injury involving a spiral fracture of the proximal fibula with an associated ankle sprain and/or medial malleolar fracture. In this instance, the fracture is displaced, affects an unspecified leg, and is an open fracture of severe type (IIIA, IIIB, or IIIC) that is experiencing delayed healing.

Use this code for a patient presenting for follow-up care of a previously diagnosed and treated displaced Maisonneuve's fracture, where the initial injury was an open fracture classified as type IIIA, IIIB, or IIIC, and the healing process is taking longer than expected. This code is appropriate when the patient is still receiving active treatment for the delayed union or nonunion of this specific fracture type.

• Ensure documentation clearly specifies "delayed healing" for this subsequent encounter.
• Verify the original fracture was indeed an open fracture classified as type IIIA, IIIB, or IIIC.
• Do not use for initial treatment or for routine follow-up of a healing fracture without documented delayed healing.
