Displ oblique fx shaft of l fibula, 7thR

This code signifies a previously treated oblique fracture of the shaft of the left fibula that was initially an open fracture (Type IIIA, IIIB, or IIIC) and has now healed incorrectly, resulting in a malunion. The displacement of the fracture fragments indicates they are not in their anatomical alignment.

Use this code when documenting follow-up care for a patient whose open left fibula shaft fracture (oblique type) has healed with a deformity or angulation, requiring further medical intervention or assessment. This applies to subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status for this previously open fracture.
• Verify the fracture type was indeed oblique and located in the shaft of the left fibula.
• Confirm the original open fracture was classified as Type IIIA, IIIB, or IIIC.
