CPT® Code 34401

Thrombectomy is a surgical procedure aimed at the removal of a thrombus, which is a blood clot that obstructs blood flow within a vein. This specific procedure, identified by CPT® Code 34401, involves the vena cava or iliac vein and is performed through an abdominal incision. The thrombus typically forms in areas where the vein is narrowed or stenotic, leading to potential complications such as swelling, pain, or even more severe vascular issues. During the thrombectomy, an incision is made in the abdomen to access the affected vein directly. In some cases, a catheter may be utilized to assist in the removal of the thrombus, allowing for a less invasive approach. The procedure may also involve the placement of vessel loops to control blood flow, ensuring that the surgical site is adequately managed during the thrombus removal process. Following the extraction of the clot, a venography may be conducted to confirm that the vein is clear and that normal blood flow has been restored. This procedure is critical for patients experiencing significant vascular obstruction due to thrombus formation, and it is essential for medical coders and billers to accurately document the specifics of the procedure for proper reimbursement and compliance.
