Displ spiral fx shaft of l fibula, 7thN

This code signifies a left fibula shaft fracture that is both displaced and spiral in nature, which has failed to heal properly (nonunion). Crucially, this fracture was initially an open fracture of a severe type (IIIA, IIIB, or IIIC), indicating significant soft tissue damage and bone exposure at the time of injury. The "subsequent encounter" aspect means the patient is receiving ongoing care for this unhealed fracture.

This code is appropriate for documenting follow-up visits, surgical interventions, or ongoing management for a patient whose initial severe open left fibula shaft fracture has not united. It should be used when the fracture is confirmed to be displaced, spiral, and in a state of nonunion, and the original injury was classified as an open fracture type IIIA, IIIB, or IIIC.

• Ensure documentation clearly specifies "nonunion" and the initial open fracture type (IIIA, IIIB, or IIIC).
• Verify the fracture is of the left fibula shaft, displaced, and spiral in morphology.
• Confirm this is a subsequent encounter for ongoing care, not the initial treatment of the fracture.
