Disp fx of l tibial tuberosity, 7thN

This code describes a specific type of fracture involving the left tibial tuberosity that has not healed properly (nonunion) and is displaced. It indicates that the initial injury was an open fracture, specifically a severe Gustilo-Anderson type IIIA, IIIB, or IIIC, and that this encounter is for follow-up care after the initial treatment.

This code is appropriate for documenting subsequent encounters for patients with a previously treated, displaced open fracture of the left tibial tuberosity (Gustilo-Anderson type IIIA, IIIB, or IIIC) who are now experiencing nonunion. It would be used when the patient presents for ongoing management, evaluation, or treatment related to the unhealed fracture.

• Ensure documentation clearly specifies "displaced" and "nonunion" for the left tibial tuberosity.
• Verify the original injury was classified as an open fracture type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters, not the initial treatment of the fracture.
