Displ bicondylar fx unsp tibia, 7thM

This code signifies a complex fracture involving both condyles of the tibia, which has shifted from its normal anatomical position. The fracture is an open type I or II, meaning there's a wound communicating with the fracture site, and the bone fragments have failed to heal together after an initial treatment.

This code is appropriate for encounters where a patient with a previously diagnosed displaced bicondylar open tibial fracture (Type I or II) is being treated for nonunion. This would include follow-up visits, further surgical interventions, or management of complications related to the nonunion.

• Ensure documentation clearly specifies "nonunion" as the reason for the subsequent encounter.
• Verify the fracture is explicitly described as "bicondylar" and "displaced."
• Confirm the open fracture type (I or II) is documented, as this code is specific to those types.
