Displ Maisonneuve's fx l leg, 7thH

This code describes a specific type of ankle fracture where the fibula is broken high up in the leg, near the knee, along with an ankle injury, and the bone fragments are not properly aligned. The skin and soft tissues are also compromised, indicating an open fracture (Type I or II), and the healing process is taking longer than expected. This injury affects the stability of the ankle joint.

Use this code for a patient presenting for follow-up care of a previously diagnosed and treated Maisonneuve's fracture of the left leg, where the fracture was initially open (Type I or II) and is now experiencing delayed union or nonunion. This applies when the patient is still actively receiving treatment for the delayed healing.

• Ensure documentation specifies "left leg" and "displaced" for accurate coding.
• Verify the encounter is for subsequent care and that delayed healing of an open fracture (Type I or II) is explicitly documented.
• Do not use if the fracture is closed, nondisplaced, or if healing is progressing normally.
