Displ bicondylar fx unsp tibia, 7thN

This code signifies a complex fracture involving both condyles of the tibia, where the bone fragments are out of alignment. It specifically indicates that the fracture is an open injury (skin broken) of a severe type (IIIA, IIIB, or IIIC) and has failed to heal properly in a subsequent encounter.

This code is appropriate for documenting follow-up care for a patient with a previously treated bicondylar tibial fracture that was open and is now complicated by nonunion. It would be used when the patient presents for ongoing management, such as further surgical intervention, bone grafting, or prolonged immobilization due to the healing failure.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (IIIA, IIIB, or IIIC).
• Verify this is a subsequent encounter, not the initial treatment of the fracture.
• Confirm the fracture involves both tibial condyles and is displaced.
