Nondisp spiral fx shaft of l fibula, 7thN

This code describes a specific type of left lower leg injury: a spiral fracture of the fibula shaft that is not displaced. Importantly, this fracture is an open fracture (meaning the skin was broken) of a severe type (IIIA, IIIB, or IIIC) and has failed to heal properly, indicating a nonunion.

This code is used when a patient with a previously diagnosed nondisplaced spiral open fracture (Type IIIA, IIIB, or IIIC) of the left fibula shaft is presenting for follow-up care, and the fracture has not healed. This implies ongoing management of the nonunion, which may include further surgical intervention, bone grafting, or prolonged immobilization.

• Ensure documentation clearly specifies "nondisplaced" and "spiral" fracture of the fibula shaft.
• Verify the encounter is for the subsequent management of the nonunion, not the initial treatment.
• Confirm the original open fracture was classified as Type IIIA, IIIB, or IIIC based on Gustilo-Anderson classification.
