CPT® Code 73620

A radiologic examination of the foot, designated by CPT® Code 73620, involves capturing images of the bones located in the distal lower extremity. This examination may encompass various bones, including the tibia, fibula, talus, calcaneus, cuboid, navicular, cuneiform, metatarsals, and phalanges. The process utilizes X-ray imaging, which employs indirect ionizing radiation to create internal images of the body. X-rays are particularly effective on non-uniform materials, such as human tissue, due to the varying densities and compositions of the structures being imaged. As a result, some X-rays are absorbed by the tissues while others pass through, allowing for the creation of a two-dimensional image on a detector positioned behind the object. The primary purpose of foot X-rays is to investigate the underlying causes of symptoms such as pain, limping, or swelling. They are also instrumental in diagnosing various conditions, including fractures, dislocations, deformities, degenerative diseases, osteomyelitis, arthritis, foreign bodies, and cysts or tumors. Additionally, these radiographs can be utilized to assess the alignment of foot bones following treatment for fractures. Standard views captured during this examination typically include dorsal plantar (DP), lateral (side), oblique (semi-prone position with the body and leg partially rotated), and stress studies, which involve applying traction to the joint manually. The specific code 73620 is designated for reporting an X-ray examination of the foot that includes two views, while code 73630 is reserved for a more comprehensive examination that encompasses a minimum of three views.
