CPT® Code 73562

A radiologic examination of the knee, designated by CPT® Code 73562, involves capturing images of the knee joint through X-ray technology. This procedure specifically includes three distinct views of the knee, which are essential for a comprehensive assessment of the joint's structure and any potential abnormalities. The examination focuses on key anatomical components such as the femur, tibia, fibula, patella, and surrounding soft tissues. X-ray imaging operates on the principle of indirect ionizing radiation, which allows for the visualization of internal body structures by exploiting the varying densities and compositions of different materials, such as human tissue. During the X-ray process, some of the emitted X-rays are absorbed by the denser structures, while others pass through and are captured on a detector, resulting in a two-dimensional representation of the knee's anatomy. This imaging technique is particularly valuable for diagnosing a range of conditions, including but not limited to fractures, dislocations, deformities, degenerative diseases, osteomyelitis, arthritis, foreign bodies, and cysts or tumors. Additionally, knee X-rays can be instrumental in evaluating the alignment of lower extremity bones after fracture treatment. The standard views obtained during this examination include the anteroposterior (AP) view, which captures the knee from front to back, the lateral view, which shows the knee from the side, and the posteroanterior (PA) view, which provides a back-to-front perspective. Variations in joint flexion and the patient's weight-bearing status may also be considered during the imaging process. For procedures requiring fewer views, CPT® Code 73560 is applicable for one or two views, while CPT® Code 73564 is used for a complete examination involving four or more views. Furthermore, CPT® Code 73565 is designated for weight-bearing X-ray examinations of both knees taken on a single film.
