CPT® Code 72190

A radiologic examination of the pelvis, designated by CPT® Code 72190, involves a comprehensive diagnostic X-ray procedure that captures a minimum of three distinct views of the pelvic region. This examination utilizes 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 different materials, such as human tissues. When X-rays are directed towards the body, some rays are absorbed by denser materials like bones, while others pass through softer tissues, resulting in a two-dimensional image that highlights these differences. In the resulting images, bones typically appear white due to their density, whereas soft tissues and fluids are represented in various shades of gray. Pelvic X-rays are particularly indicated when patients present with symptoms such as pain or injury in the pelvic area or hip joints. This examination is crucial for assessing potential fractures, detecting arthritis, or identifying other bone diseases. During the procedure, the patient is positioned on an examination table, and various views of the pelvis are obtained by adjusting the position of the legs and feet. For instance, the patient may be instructed to turn their feet inward to point towards each other or to bend their knees outward with the soles of their feet together in a 'frog-leg' position. It is important to note that for a complete pelvic X-ray examination consisting of three or more views, CPT® Code 72190 should be reported, whereas CPT® Code 72170 is applicable for examinations with only one to two views.
