Displ spiral fx shaft of l tibia, 7thN

This code describes a situation where a patient has a spiral fracture of the shaft of their left tibia that is displaced, meaning the bone fragments are not properly aligned. Crucially, this fracture is an open fracture (types IIIA, IIIB, or IIIC), indicating a break in the skin and exposure of the bone, and it has failed to heal properly, resulting in a nonunion. This code is used for encounters following the initial treatment of the fracture.

This code is appropriate for documenting follow-up care for a patient whose displaced open spiral fracture of the left tibial shaft has not healed and is now considered a nonunion. This includes scenarios such as ongoing management, evaluation for surgical intervention to address the nonunion, or monitoring of conservative treatment for the nonunion. It should be used when the patient is seen for issues directly related to the nonunion of this specific fracture.

• Ensure documentation clearly specifies "nonunion" and the "open" nature (types IIIA, IIIB, or IIIC) of the original fracture.
• Verify laterality (left tibia) and the specific fracture type (spiral fracture of the shaft).
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
