CPT® Code 23350

The injection procedure for shoulder arthrography, designated by CPT® Code 23350, involves a series of steps aimed at enhancing imaging of the shoulder joint. This procedure is essential for visualizing the internal structures of the shoulder, which may include bones, cartilage, ligaments, and tendons. The process begins with the cleansing of the skin at the injection site to minimize the risk of infection. Following this, a local anesthetic is administered to ensure patient comfort during the procedure. A needle is then carefully inserted into the shoulder joint, allowing for the aspiration of any existing fluid, which may be necessary for diagnostic purposes. Subsequently, a radiopaque substance, which is a contrast agent that appears white on imaging studies, is injected into the joint space. This injection is typically performed under fluoroscopic guidance, a real-time imaging technique that helps the physician accurately place the needle and ensure proper distribution of the contrast material. After the injection, the patient may be asked to move the shoulder to facilitate even distribution of the radiopaque substance throughout the joint. This enhanced visualization is crucial for obtaining high-quality radiographic images or for conducting advanced imaging techniques such as computed tomography (CT) or magnetic resonance imaging (MRI), which can provide detailed insights into the shoulder's anatomy and any potential pathologies present.
