CPT® Code 49400

The CPT® Code 49400 refers to the procedure involving the injection of air or contrast material into the peritoneal cavity, which is classified as a separate procedure. This technique is typically performed using radiographic guidance, which allows for precise needle placement. The procedure begins with the insertion of a needle through the abdominal wall into the peritoneal cavity, the space within the abdomen that houses various organs. Once the needle is correctly positioned, air may be injected to create a pneumoperitoneum, a condition where air is introduced into the peritoneal cavity, often utilized for diagnostic purposes or to facilitate other procedures. Alternatively, a contrast agent may be injected, which is a substance that enhances the visibility of structures within the peritoneal cavity during imaging studies. Following the injection, separate reportable radiographs, or X-ray images, are obtained to visualize the distribution of the air or contrast within the cavity, aiding in the assessment of abdominal conditions or guiding further interventions. This procedure is essential in various diagnostic and therapeutic contexts, providing valuable information for healthcare professionals in managing patient care.
