CPT® Code 93573

Add-On Code

Injection procedure during cardiac catheterization including imaging supervision, interpretation, and report; for selective pulmonary arterial angiography, bilateral (List separately in addition to code for primary procedure)

The CPT® Code 93573 refers to an injection procedure performed during cardiac catheterization specifically for selective pulmonary arterial angiography on a bilateral basis. This procedure is typically conducted in conjunction with a primary right heart catheterization, which is a diagnostic technique used to assess the heart's function and blood flow. The selective pulmonary arterial angiography is particularly relevant for evaluating congenital heart defects, especially in pediatric patients, although it can also be applicable to adults with acquired conditions. During this procedure, a diagnostic catheter is strategically positioned within the main pulmonary artery, allowing for the administration of contrast media. This contrast agent is essential for opacifying the pulmonary artery, enabling detailed visualization of its structure and function. The procedure aims to identify any abnormalities such as valve regurgitation, irregular blood flow, or vascular anomalies. The process involves careful monitoring of the patient's vital signs, including arterial pressure, heart rhythm, and oxygen saturation, throughout the procedure and during the recovery phase to ensure patient safety and to detect any potential complications, such as allergic reactions or kidney damage. The results of the angiography are meticulously reviewed by the physician, who provides a comprehensive written interpretation of the findings, which is crucial for guiding further clinical decisions.
