CPT® Code 93586

Add-On Code

Venography for congenital heart defect(s), including catheter placement, and radiological supervision and interpretation; coronary sinus (List separately in addition to code for primary procedure)

This procedure, identified by CPT® Code 93586, refers to a specialized venography performed specifically for patients with congenital heart defects. The term 'venography' denotes a radiographic examination of veins, which in this context focuses on the coronary sinus, the principal vein responsible for draining deoxygenated blood from the heart muscle into the right atrium. This procedure is typically conducted as an add-on service during a primary diagnostic cardiac catheterization, which is a common method used to evaluate heart conditions. The coronary sinus plays a crucial role in the circulatory system of the heart, particularly in patients who have undergone surgical interventions for congenital heart defects, such as the Fontan procedure. This surgical technique is often employed in cases where only one ventricle is functioning, necessitating a unique approach to blood circulation. The venography allows for detailed visualization of the coronary sinus, enabling healthcare providers to assess blood flow and identify any potential complications or abnormalities associated with congenital heart defects. The procedure involves the placement of a catheter into the coronary sinus, followed by the injection of contrast material to enhance imaging clarity, allowing for accurate interpretation and diagnosis by radiological professionals.
