CPT® Code 27509

Percutaneous skeletal fixation of femoral fracture, distal end, medial or lateral condyle, or supracondylar or transcondylar, with or without intercondylar extension, or distal femoral epiphyseal separation

The procedure described by CPT® Code 27509 involves the percutaneous skeletal fixation of a femoral fracture located at the distal end of the femur, specifically targeting the medial or lateral condyle, as well as supracondylar or transcondylar fractures. In simpler terms, the distal femur features two prominent projections known as the lateral and medial epicondyles. When fractures occur just above these epicondyles, they are classified as supracondylar fractures, while those that occur through the epicondyles are termed transcondylar fractures. These fractures can also extend into the intercondylar fossa, which is the space between the epicondyles, or may lead to the separation of the epiphyseal plate, particularly in younger patients. Prior to the fixation procedure, separate radiographs are obtained to confirm the presence and specifics of the fracture. A thorough neurovascular examination is conducted to ensure that the nerves and blood vessels surrounding the injury are intact and functioning properly. The procedure itself involves making a small incision over the distal femur, followed by the use of radiographic guidance to create one or more corticotomies—small cuts in the bone—at the designated sites for pin placement. The fracture fragments are then manually manipulated back into their correct anatomical positions, and pins are inserted across the fracture site to maintain this alignment. Finally, the correct anatomical reduction is confirmed through radiographic imaging, ensuring that the fracture is properly stabilized.
