Official Description

Endovascular stent repair of coarctation of the ascending, transverse, or descending thoracic or abdominal aorta, involving stent placement; not crossing major side branches

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 33895 involves the endovascular stent repair of coarctation, which refers to a narrowing of the aorta, specifically in the ascending, transverse, or descending thoracic or abdominal regions. This condition is often congenital, meaning it is present at birth, but may not manifest until later in life. In some instances, aortic coarctation can arise due to trauma, severe atherosclerosis, or inflammation. The endovascular approach utilizes a catheter, which is a thin, flexible tube, to navigate through the vascular system. The catheter is inserted into the iliac artery via a small access point in the groin and is guided under imaging techniques into the aorta, precisely positioning it at the site of the narrowing. Once in place, a balloon at the tip of the catheter is inflated to widen the constricted area of the aorta. Following this, a mesh stent is deployed to keep the artery open, ensuring that blood can flow freely. This minimally invasive technique is preferred over traditional open surgery due to its reduced recovery time and lower risk of complications. However, there remains a possibility that the coarctation may recur, necessitating further intervention. It is important to note that untreated aortic coarctation can lead to serious health issues, including brain aneurysms, aortic dilation or rupture, heart failure, stroke, and early onset of coronary artery disease.

1. Indications

The endovascular stent repair of coarctation of the aorta, as described by CPT® Code 33895, is indicated for patients presenting with the following conditions:

  • Coarctation of the Aorta - A narrowing of the aorta that can lead to significant cardiovascular complications if left untreated.
  • Congenital Aortic Coarctation - A condition present at birth that may not become symptomatic until later in life.
  • Acquired Aortic Coarctation - Coarctation that may develop due to trauma, severe atherosclerosis, or inflammation.

2. Procedure

The procedure for endovascular stent repair of aortic coarctation involves several critical steps:

  • Step 1: Access Site Preparation - The procedure begins with the preparation of the access site, typically the groin area, where a small incision is made to access the iliac artery. This site is cleaned and sterilized to minimize the risk of infection.
  • Step 2: Catheter Insertion - A catheter is inserted into the iliac artery through the access point. This catheter is designed to be flexible, allowing it to navigate through the vascular system with ease.
  • Step 3: Navigation to the Aorta - Under imaging guidance, the catheter is carefully threaded through the iliac artery and into the aorta. The physician ensures that the catheter is positioned accurately at the site of the coarctation.
  • Step 4: Balloon Deployment - Once the catheter is in place, a balloon located at the tip of the catheter is inflated. This inflation expands the narrowed section of the aorta, effectively widening the artery to improve blood flow.
  • Step 5: Stent Placement - Following the balloon dilation, a mesh stent is deployed through the catheter. The stent is positioned at the site of the coarctation to maintain the newly expanded diameter of the aorta, preventing re-narrowing.
  • Step 6: Catheter Removal and Site Closure - After the stent is successfully placed, the catheter is carefully removed. The access site is then closed, and appropriate measures are taken to ensure proper healing.

3. Post-Procedure

Post-procedure care for patients undergoing endovascular stent repair of aortic coarctation includes monitoring for any immediate complications, such as bleeding or infection at the access site. Patients are typically observed for a short period in a recovery area before being discharged. Follow-up appointments are essential to assess the stent's position and function, as well as to monitor for any potential recurrence of coarctation. Patients may be advised on activity restrictions and signs of complications to watch for during their recovery period. It is crucial to ensure that the patient understands the importance of follow-up care to maintain cardiovascular health and address any issues that may arise.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
