CPT® Code 72110

A radiologic examination of the lumbosacral spine, designated by CPT® Code 72110, involves capturing a minimum of four distinct views of the lower back region, specifically the lumbosacral area where the lumbar spine meets the sacrum. This procedure utilizes X-ray technology, which employs indirect ionizing radiation to create images of the internal structures of the body. The X-ray process is effective due to the varying densities and compositions of human tissues, allowing some X-rays to be absorbed while others pass through. The resulting images are two-dimensional representations that provide critical insights into the condition of the spine. In this examination, the most common projections include frontal, posteroanterior, and lateral views, which are essential for a comprehensive assessment of the lumbosacral spine. If fewer than four views are taken, the appropriate code to report would be 72100. For a more extensive evaluation, a complete lumbosacral spine exam, coded as 72114, requires a minimum of six views, which may include additional angles such as oblique views and dynamic positions like flexion and extension. These additional views are particularly useful in trauma assessments, where the integrity of the spine must be thoroughly evaluated. The procedure may also involve lateral bending positions, where the patient is positioned to flex the back to each side while maintaining contact with a stool, ensuring stability during the examination. Overall, CPT® Code 72110 is crucial for accurately documenting and billing for a detailed radiologic assessment of the lumbosacral spine.
