The CPT® Code 93575 refers to an injection procedure performed during cardiac catheterization, specifically for selective pulmonary angiography of major aortopulmonary collateral arteries (MAPCAs) that arise from the aorta or its systemic branches. This procedure is particularly relevant in the context of congenital heart defects, where MAPCAs serve as alternative pathways for blood flow to the lungs. In normal physiology, blood is directed to the lungs via the pulmonary arteries; however, in patients with MAPCAs, blood is instead supplied through these collateral arteries directly off the aorta. This condition is often identified in newborns and can be associated with other congenital anomalies such as Tetralogy of Fallot, pulmonary valve atresia, or ventricular septal defects. During the cardiac catheterization, a catheter is carefully advanced into the aorta, and a guidewire is utilized to locate the targeted aortopulmonary collateral vessels. Once the catheter is positioned correctly, contrast material is injected to visualize the blood flow through these vessels via angiography. This imaging process allows for the assessment of any abnormalities in the collateral arteries. Each distinct vessel that undergoes angiography is reported separately using code 93575, ensuring that the complexity and extent of the procedure are accurately captured. Throughout the procedure, the patient's vital signs, including arterial pressure, heart rhythm, and oxygen saturation, are closely monitored to ensure safety and to detect any potential complications, such as allergic reactions or arrhythmias.

The procedure described by CPT® Code 93575 is indicated for patients with congenital heart defects that involve major aortopulmonary collateral arteries (MAPCAs). The following conditions may warrant this procedure:
The procedure for CPT® Code 93575 involves several detailed steps to ensure accurate imaging of the major aortopulmonary collateral arteries. The process begins with the insertion of a catheter into the aorta during a diagnostic cardiac catheterization. The physician carefully advances a guidewire through the catheter to locate the targeted aortopulmonary collateral vessels. Once the guidewire is positioned correctly, the catheter is advanced over the wire to the specific vessel of interest. The physician checks the catheter's positioning to ensure it is correctly placed within the target vessel. After confirming the position, the guidewire is removed, and contrast material is manually injected into the vessel. This injection allows for the performance of an angiogram, which visualizes the blood flow and any potential abnormalities in the collateral arteries. Following the angiogram, the catheter is withdrawn back into the aorta, and the guidewire is reinserted to maneuver to the next target vessel. This process is repeated for each distinct vessel that requires imaging. Each angiogram performed is reported separately using code 93575, and the resulting images are processed and reviewed by the physician, who provides a written interpretation of the findings.
After the completion of the angiography procedure, the patient is closely monitored for any adverse reactions to the contrast material, such as allergic reactions, as well as for arrhythmias or other complications that may arise. Continuous monitoring of the patient's arterial pressure, heart rhythm, and oxygen levels is essential during the recovery phase. The healthcare team remains vigilant for signs of kidney damage, which can occur due to contrast-induced nephropathy. The patient may require additional follow-up care based on the findings from the angiograms and the overall clinical picture. Documentation of the procedure, including the interpretation of the angiograms, is essential for ensuring proper coding and billing, as well as for guiding any subsequent treatment decisions.
