Disp fx of lateral condyle of unsp tibia, 7thN

This code describes a displaced fracture of the outer portion of the shin bone (tibia) near the knee joint that has failed to heal properly after an initial open fracture. The "open" nature indicates the skin was broken, and the "IIIA, IIIB, or IIIC" specifies a severe type of open fracture with significant soft tissue damage. "Subsequent encounter" means the patient is receiving follow-up care for this non-healing fracture.

Use this code when documenting ongoing treatment for a patient whose previously sustained open fracture of the lateral tibial condyle (Gustilo-Anderson type IIIA, IIIB, or IIIC) has not united. This applies to situations such as surgical intervention for nonunion, cast changes, or wound care related to the non-healing fracture.

• Ensure documentation clearly specifies "nonunion" and the Gustilo-Anderson classification for the original open fracture.
• Verify the fracture is specifically of the lateral condyle of the tibia.
• Confirm this is a "subsequent encounter" for ongoing management of the nonunion, not the initial treatment of the fracture.
