CPT® Code 74020

Deleted

A radiologic examination of the abdomen, designated by CPT® Code 74020, is a comprehensive imaging procedure that captures detailed images of the internal organs, soft tissues, and skeletal structures within the abdominal cavity. This examination employs X-ray technology, which utilizes indirect ionizing radiation to create images of the body's internal components. The process relies on the varying densities and compositions of human tissues, allowing certain X-rays to be absorbed while others pass through, ultimately forming a two-dimensional representation of the anatomical structures. The resulting radiographs are instrumental in assessing various conditions by providing insights into the size, shape, and position of organs, as well as identifying patterns of air (bowel gas), obstructions, foreign objects, and calcifications in critical areas such as the gallbladder, urinary tract, and aorta. The procedure may be indicated for a range of clinical scenarios, including the evaluation of abdominal distention and pain, vomiting, diarrhea, constipation, and traumatic injuries. Additionally, it can serve as a preliminary screening exam or scout film prior to more advanced imaging techniques. Commonly performed views during this examination include the anteroposterior (AP) view with the patient either lying supine or standing erect, the posteroanterior (PA) view with the patient lying prone, lateral views with the patient on their side, and various decubitus views. The complete radiologic examination as denoted by Code 74020 encompasses both the AP view and a decubitus view, providing a thorough assessment of the abdominal area.
