CPT® Code 73600

A radiologic examination of the ankle, designated by CPT® Code 73600, involves capturing images of the bones located in the distal lower extremities, specifically the tibia, fibula, and talus. This procedure utilizes X-ray imaging, which employs indirect ionizing radiation to create internal images of the body. 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 less dense areas, allowing for the formation of a two-dimensional image on a detector positioned behind the body. This imaging technique is particularly useful for diagnosing various conditions that may cause symptoms such as pain, limping, or swelling in the ankle region. The radiologic examination can reveal critical information regarding fractures, dislocations, deformities, degenerative diseases, osteomyelitis, arthritis, foreign bodies, and the presence of cysts or tumors. Additionally, ankle X-rays are instrumental in assessing the alignment of lower extremity bones after treatment for fractures, ensuring that healing is progressing correctly. The standard views captured during this examination typically include anteroposterior (AP), lateral, oblique, and, in some cases, a stress study where traction is applied to the joint manually. It is important to note that CPT® Code 73600 specifically refers to an X-ray examination of the ankle that includes two views, while CPT® Code 73610 is designated for a more comprehensive examination that encompasses a minimum of three views.
