CPT® Code 93569

Add-On Code

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

The CPT® Code 93569 refers to an injection procedure performed during cardiac catheterization specifically for selective pulmonary arterial angiography on a unilateral 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 patients with congenital heart defects, often seen in pediatric populations, although it can also be applicable to adults with acquired conditions. During this procedure, a diagnostic catheter is initially positioned in the main pulmonary artery, allowing for the administration of contrast media to visualize the pulmonary artery and its branches. The goal is to identify any abnormalities such as valve regurgitation, irregular blood flow, or structural issues within the vessels. The process involves the introduction of a guidewire into a distal segmental branch of the pulmonary artery, facilitating a more targeted and detailed examination. This procedure is crucial for diagnosing and managing various cardiac conditions, ensuring that any potential issues are accurately identified and documented for further treatment planning.
