CPT® Code 73560

A radiologic examination of the knee, designated by CPT® Code 73560, involves capturing images of the knee joint, which includes the femur, tibia, fibula, patella, and surrounding soft tissue. This procedure utilizes X-ray imaging, a technique that employs indirect ionizing radiation to create visual representations of internal body structures. The principle behind X-ray imaging is based on the varying densities and compositions of human tissues; as X-rays pass through the body, some are absorbed by denser materials while others penetrate through, allowing for the formation of a two-dimensional image on a detector positioned behind the body. This imaging technique is particularly useful for diagnosing a range of conditions that may cause knee pain, limping, or swelling. Common indications for performing knee X-rays include the assessment of fractures, dislocations, deformities, degenerative diseases, osteomyelitis, arthritis, the presence of foreign bodies, and the identification of cysts or tumors. Additionally, knee X-rays can be instrumental in evaluating the alignment of lower extremity bones after fracture treatment to ensure proper healing and positioning. The standard views captured during this examination typically include the anteroposterior (AP) view, which is taken from front to back, the lateral view from the side, and the posteroanterior (PA) view, which is taken from back to front. Variations in joint flexion and the patient's weight-bearing status may also be considered during the imaging process. CPT® Code 73560 specifically applies to X-ray examinations of the knee that are conducted in one or two views, distinguishing it from other codes that represent more extensive imaging protocols.
