2025 CPT code 75957
(Active) Effective Date: N/A Radiology - Diagnostic Radiology (Diagnostic Imaging) Feed
Endovascular repair of descending thoracic aorta (e.g., aneurysm, pseudoaneurysm); not involving coverage of left subclavian artery origin, initial endoprosthesis plus descending thoracic aortic extension(s), if required, to level of celiac artery origin, radiological supervision and interpretation.
Modifiers 26 (professional component) and TC (technical component) can be applied. Modifier 52 (reduced services) may be applicable if the service is significantly reduced.
Medical necessity for this procedure is established by documentation of a condition affecting the descending thoracic aorta, such as an aneurysm, pseudoaneurysm, dissection, penetrating ulcer, intramural hematoma, or traumatic disruption, that requires endovascular repair.
The physician is responsible for the radiological supervision and interpretation of the entire procedure, including pre-procedural imaging, intra-procedural guidance, and post-procedural assessment. This includes selecting and deploying the endoprosthesis and extensions.
In simple words: This procedure involves image-guided repair of a damaged section of the large artery in the chest (descending thoracic aorta) using a stent-like device. The doctor uses x-ray imaging to guide the placement of the device inside the artery to reinforce the weakened area. This is done through a small incision, usually in the groin or arm.
This code describes radiological supervision and interpretation for endovascular repair of the descending thoracic aorta using an initial endoprosthesis and possible extensions to the celiac artery, when the repair does not involve the left subclavian artery.This includes imaging guidance for deployment of the endoprosthesis, as well as any necessary extensions. Diagnostic angiography performed at the time of the therapeutic service is included. However, separate diagnostic angiography may be reported if not available or inadequate.
Example 1: A patient presents with a descending thoracic aorta aneurysm. The physician performs an endovascular repair, excluding the left subclavian artery, using an initial endoprosthesis and a single extension to the level of the celiac artery under fluoroscopic guidance., A patient with a traumatic disruption of the descending thoracic aorta undergoes endovascular repair. The left subclavian artery is not involved. The physician places the initial endoprosthesis, followed by multiple extensions to reach the celiac artery origin, using radiological imaging for guidance., A patient has a penetrating ulcer in the descending thoracic aorta.Endovascular repair is performed without involvement of the left subclavian artery.Radiological supervision and interpretation are provided for placement of the initial endoprosthesis. No extensions are required in this case.
Documentation should include the pre-procedural imaging findings, the type and size of the endoprosthesis and any extensions used, the location of deployment within the aorta, intra-procedural imaging details, and post-procedural results. Any complications encountered should also be documented.
