CPT® Code 73522

A radiologic examination, specifically CPT® Code 73522, refers to a diagnostic imaging procedure that involves taking X-ray images of both the left and right hips, and may also include the pelvis if performed. This examination utilizes X-ray technology, which employs indirect ionizing radiation to create images of the internal structures of the body. The principle behind X-ray imaging is based on the varying densities and compositions of human tissues, which affect how X-rays are absorbed or transmitted. As a result, some X-rays are absorbed by denser materials, such as bones, while others pass through less dense tissues, allowing for the creation of a two-dimensional image on a detector positioned behind the body. The primary purpose of this examination is to evaluate the hips for various medical conditions. Common indications for performing this procedure include the assessment of fractures, dislocations, deformities, degenerative bone diseases, osteomyelitis, arthritis, the presence of foreign bodies, infections, or tumors. The standard views typically captured during this examination include the anteroposterior view, where the patient lies supine with legs straight and slightly rotated inward; the lateral 'frog-leg' view, which requires the hips to be flexed and abducted with knees bent and soles of the feet together; and a cross-table view, where the unaffected hip and knee are flexed at a 90-degree angle to allow for optimal imaging of the affected side. Additionally, a pelvic view may be included, which is often taken with the patient in a supine position and both legs rotated inward slightly. This comprehensive approach to imaging the hips ensures that a thorough evaluation can be conducted, aiding in accurate diagnosis and treatment planning.
