Nondisp Maisonneuve's fx r leg, 7thR

This code describes a Maisonneuve's fracture of the right leg, 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 fragments are in their normal anatomical alignment (nondisplaced), but the bone has healed in an imperfect position (malunion). This particular code is used during a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and potential contamination.

Use this code when documenting follow-up care for a patient who previously sustained an open Maisonneuve's fracture of the right leg, specifically types IIIA, IIIB, or IIIC, and is now presenting with evidence of malunion. This applies to situations where the initial injury was an open fracture, and the current encounter addresses complications related to the healing process, such as pain, functional limitations, or deformity due to the malunion.

• Ensure documentation clearly specifies "nondisplaced" and "malunion" for the Maisonneuve's fracture.
• Verify the original injury was an "open fracture type IIIA, IIIB, or IIIC" of the right leg to justify the "subsequent encounter" designation.
• Do not use this code for initial encounters or for closed fractures, or if the fracture has healed with normal alignment.
