Displaced bicondylar fx l tibia, subs for clos fx w nonunion

This code signifies a fracture involving both condyles of the left tibia that is out of alignment, where the patient is receiving ongoing care for the fracture, and the bone fragments have failed to heal together. "Nonunion" indicates that the fracture has not mended and is unlikely to do so without further intervention.

Use this code for follow-up visits, cast changes, or other ongoing treatment for a displaced bicondylar left tibial fracture that has been diagnosed with nonunion and is still considered a closed fracture. This applies when the patient is beyond the initial healing phase but the fracture has not united.

• Ensure documentation clearly states "nonunion" and specifies the "left tibia" and "bicondylar" nature of the fracture.
• Verify that the encounter is for subsequent care and not the initial treatment of the fracture.
• Confirm the fracture is still considered "closed" (skin intact) to avoid using open fracture codes.
