CPT® Code 74018

A radiologic examination of the abdomen, designated by CPT® Code 74018, involves the use of X-ray technology to create images of the internal structures within the abdominal cavity. This procedure captures the soft tissues, organs, and skeletal components of the abdomen, providing critical insights into their condition and arrangement. The X-ray imaging technique employs indirect ionizing radiation, which interacts with the varying densities and compositions of human tissues. As a result, some X-rays are absorbed while others pass through, allowing for the generation of a two-dimensional image that reveals the anatomical features of the abdomen. This examination is particularly useful for assessing the size, shape, and position of abdominal organs, as well as identifying patterns of air, potential obstructions, foreign objects, and calcifications in areas such as the gallbladder, urinary tract, and aorta. The procedure may be indicated for a variety of clinical scenarios, including the evaluation of abdominal distention and pain, episodes of vomiting, diarrhea or constipation, and traumatic injuries. Additionally, it can serve as a preliminary screening tool or scout film prior to more advanced imaging techniques. The specific code 74018 is utilized to report a single view of the abdomen, while other codes exist for multiple views, such as 74019 for two views and 74021 for three or more views. For comprehensive assessments, code 74022 is applicable for a complete acute abdomen series, which includes at least two views of the abdomen in various positions, along with a single view of the chest. Commonly performed views during this examination include anteroposterior (AP), posteroanterior (PA), lateral, lateral decubitus, oblique, and coned views, each serving distinct purposes in localizing and differentiating various abdominal conditions.
