Displ transverse fx shaft of l fibula, 7thR

This code signifies a previously treated open fracture of the left fibula's shaft, specifically a transverse break, that has since developed malunion. The initial injury was a severe open fracture (Type IIIA, IIIB, or IIIC), indicating significant soft tissue damage and bone exposure. The current encounter addresses the complication of improper healing where the bone fragments have united in a misaligned position.

Use this code for follow-up encounters when a patient presents with a malunion of a previously sustained, severe open transverse fracture of the left fibula shaft. This applies when the malunion is being evaluated, monitored, or treated, and the initial injury was an open fracture classified as Type IIIA, IIIB, or IIIC. It is appropriate for situations where the malunion is a current clinical problem requiring attention.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union" for this specific code.
• Verify the laterality (left fibula) and the specific fracture type (transverse shaft fracture) are documented.
• Confirm the initial injury was an open fracture of Type IIIA, IIIB, or IIIC; this detail is crucial for accurate code selection.
