Displ subtrochnt fx r femr, 7thN

This code signifies a right femur fracture located below the lesser trochanter but above the femoral shaft, which has failed to heal (nonunion). The fracture is open, meaning the bone broke through the skin, and is being treated during a subsequent encounter. The "IIIA, IIIB, or IIIC" specifies the severity of the open wound according to the Gustilo-Anderson classification.

Apply this code when a patient presents for follow-up care, including cast changes, wound care, or surgical intervention for a previously diagnosed displaced subtrochanteric fracture of the right femur that has not united. This code is appropriate when the initial injury was an open fracture of Gustilo-Anderson type IIIA, IIIB, or IIIC, and the nonunion is confirmed.

• Ensure documentation clearly states "nonunion" and specifies the right femur.
• Verify the encounter is "subsequent" and not initial treatment for the fracture.
• Confirm the original fracture was an open fracture classified as type IIIA, IIIB, or IIIC.
