Effective Date: N/A Radiology - Radiology Feed
Placement of distal extension prosthesis(s) (delayed) after endovascular repair of descending thoracic aorta, to the level of celiac origin, including radiological supervision and interpretation.
Modifiers 26 (professional component), TC (technical component), and 52 (reduced services) may be applicable depending on the specific circumstances.
Medical necessity for this procedure must be clearly documented. This typically involves demonstrating the presence of complications from the initial repair, such as endoleaks, or the need for extended coverage to maintain vascular integrity. The documentation should clearly link the procedure to the patient's condition and the expected clinical benefit.
The physician is responsible for the entire procedure, including patient preparation, angiography, selection of the prosthesis, insertion and placement of the prosthesis under fluoroscopic guidance, contrast injection, and interpretation of the imaging. They must also ensure appropriate documentation.
In simple words: This procedure involves placing an additional piece of artificial vessel (a stent or graft) in the lower part of the chest aorta, after a previous repair.It is done through a small incision, using X-ray guidance.A special dye is used to see the blood vessels clearly. This code covers the doctor's supervision and interpretation of the imaging during the procedure.
This code describes the placement of a distal extension prosthesis after an endovascular repair of the descending thoracic aorta, extending to the level of the celiac artery origin. It includes radiological supervision and interpretation of the procedure. This is typically performed when additional coverage is needed beyond the initial repair, often to address endoleaks or other complications. It involves advancing a prosthesis through a catheter to the target area under fluoroscopic guidance. Contrast injection and angiography are used for visualization and confirmation of proper placement. This code is reported once, regardless of the number of prostheses used.
Example 1: A patient who has previously undergone endovascular repair of the descending thoracic aorta develops an endoleak in the distal portion of the repair. A distal extension prosthesis is placed to address the leak, using fluoroscopic guidance and contrast injection., Following endovascular repair of the descending thoracic aorta, a patient develops a complication requiring extension of the existing repair to provide coverage to the level of celiac origin. This procedure involves the placement of distal extension prosthesis under radiological supervision and interpretation., A patient with a complex aortic aneurysm requires staged endovascular repair. The initial repair is performed, and later, a distal extension prosthesis is placed to complete the repair at the level of celiac origin. Fluoroscopic guidance and contrast injection are employed throughout.
Documentation should include details of the initial aortic repair, the indication for the distal extension procedure (e.g., endoleak, inadequate coverage), the type and size of prosthesis used, the location of placement, the use of fluoroscopy and contrast, and any complications encountered. Operative reports and imaging studies should be maintained.
- Modifier TC rule: Modifier TC can be used if only the technical component is being reported. The TC modifier denotes the technical component of a procedure and is appended to the CPT code when the provider bills only for the equipment, supplies, and non-physician personnel used in a procedure.
