CPT® Code 73630

A radiologic examination of the foot, designated by CPT® Code 73630, involves a comprehensive imaging process that captures detailed views of the bones in the distal lower extremity. This examination typically includes the tibia, fibula, talus, calcaneus, cuboid, navicular, cuneiform, metatarsals, and phalanges. The procedure utilizes X-ray technology, which employs indirect ionizing radiation to create images of the internal structures of the body. X-rays are particularly effective in imaging non-uniform materials, such as human tissue, due to the varying densities and compositions of these materials. As X-rays pass through the body, some are absorbed while others are transmitted, resulting in a two-dimensional representation of the anatomical structures on a detector. The primary purpose of conducting foot X-rays is to investigate the underlying causes of symptoms such as pain, limping, or swelling. Additionally, this imaging technique is instrumental in diagnosing various conditions, including fractures, dislocations, deformities, degenerative diseases, osteomyelitis, arthritis, foreign bodies, and cysts or tumors. Furthermore, foot X-rays can be utilized to assess the alignment of foot bones after treatment for fractures. The standard views captured during this examination include the dorsal plantar (DP) view, which is taken from top to bottom, the lateral view from the side, the oblique view, which involves positioning the body and leg in a semi-prone position with partial rotation, and a stress study that applies manual traction to the joint. It is important to note that CPT® Code 73630 is specifically used to report a complete X-ray examination of the foot that encompasses a minimum of three views, distinguishing it from CPT® Code 73620, which is applicable for an X-ray exam of the foot with only two views.
