CPT® Code 27513

Open treatment of femoral supracondylar or transcondylar fracture with intercondylar extension, includes internal fixation, when performed

The CPT® Code 27513 refers to the open treatment of a femoral supracondylar or transcondylar fracture that includes an intercondylar extension. This procedure is specifically designed for fractures located just above the knee joint, where the distal femur has two prominent bony projections known as the lateral and medial epicondyles. When a fracture occurs in the area above these epicondyles, it is classified as a supracondylar fracture, while fractures that traverse through the epicondyles are termed transcondylar fractures. In some cases, these fractures may extend into the intercondylar region, which is the area surrounding the intercondylar fossa of the femur. During the procedure, a surgical incision is made on the lateral side of the distal femur, extending over the knee's articular surface. The surgical team carefully dissects through the tissue down to the fascia lata, which is then split to access the underlying structures. The vastus lateralis muscle is dissected along its posterior aspect to reach the distal segment of the femur. To manage any arterial bleeding that may occur, electrocautery and ligation techniques are employed. Once the fracture site is exposed, it is meticulously cleared of any debris to facilitate proper treatment. The reduction of the fracture in the supracondylar or transcondylar region is typically achieved through indirect methods, such as applying longitudinal traction or utilizing a femoral distraction device. The choice of internal fixation is critical and is determined based on the specific characteristics of the fracture. Various internal fixation devices may be used, including low-contact dynamic compression plates, dynamic condylar screws, condylar blade plates, condylar buttress plates, locking plates, T-buttress plates, intramedullary devices (such as nails or rods), or cannulated lag screws. After successfully reducing the fracture and securing all fragments with the appropriate fixation devices, X-rays are taken to confirm that anatomic reduction has been achieved. It is important to note that CPT® Code 27513 is specifically used when the fracture extends into the intercondylar region and an arthrotomy is performed to access the intercondylar fossa, allowing for additional reconstruction of the fracture in that area.
