Displ seg fx shaft of l fibula, 7thR

This code signifies a specific type of fracture involving the shaft of the left fibula, which is displaced and segmental. It indicates a subsequent encounter for an open fracture (Type IIIA, IIIB, or IIIC) that has developed malunion. This implies the bone has healed, but in an anatomically incorrect or misaligned position.

Use this code for follow-up encounters when a patient presents with a previously treated open segmental fracture of the left fibula shaft that has healed with malunion. This is applicable when the initial injury was a severe open fracture (Gustilo-Anderson Type IIIA, IIIB, or IIIC). It should be used after the initial healing phase, when malunion is identified and being managed.

• Ensure documentation clearly specifies "subsequent encounter" and confirms malunion of a previously open fracture.
• Verify the laterality (left fibula) and the specific fracture type (displaced segmental shaft fracture).
• Do not use for initial encounters or for nonunion; malunion indicates healing in an improper alignment.
