Displ commnt fx shaft of unsp fibula, 7thN

This code signifies a complex injury involving a displaced and fragmented fracture of the fibula's shaft, where the bone has broken into multiple pieces and the ends are not properly aligned. It specifically indicates an open fracture (meaning the skin was broken) of a severe type (IIIA, IIIB, or IIIC) that has failed to heal properly, resulting in nonunion.

This code is appropriate for documenting follow-up care for a patient with a previously treated severe open comminuted fibular shaft fracture that has not united. It should be used when the patient is presenting for ongoing management of this nonunion, such as for further surgical intervention, bone grafting, or prolonged immobilization.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify laterality (left or right) if known; "unspecified" should only be used when laterality is genuinely unknown.
• Confirm this is a "subsequent encounter" and not the initial treatment for the fracture.
