CPT® Code 74022

Radiologic examination, complete acute abdomen series, including 2 or more views of the abdomen (eg, supine, erect, decubitus), and a single view chest

A radiologic examination of the abdomen, specifically a complete acute abdomen series, is a diagnostic imaging procedure that captures detailed images of the internal organs, soft tissues, and supporting skeletal structures within the abdominal cavity. This examination employs X-ray technology, which utilizes indirect ionizing radiation to produce images by taking advantage of the varying densities and compositions of human tissues. The differing densities allow certain X-rays to be absorbed while others pass through, resulting in a two-dimensional representation of the anatomical structures. The primary purpose of this examination is to evaluate the size, shape, and position of abdominal organs, as well as to assess patterns of air within the bowel, identify obstructions, detect foreign objects, and observe calcifications in areas such as the gallbladder, urinary tract, and aorta. A complete acute abdomen series is typically ordered to aid in the diagnosis of various conditions, including abdominal distention and pain, vomiting, diarrhea, constipation, and traumatic injuries. Additionally, this examination may serve as a preliminary screening or scout film prior to more advanced imaging procedures. The CPT® Code 74022 specifically denotes this complete series, which includes at least two views of the abdomen—such as supine, erect, or decubitus positions—along with a single view of the chest. This comprehensive approach ensures that a thorough assessment of the abdominal area is conducted, facilitating accurate diagnosis and subsequent management of the patient's condition.
