What 34001 covers
A vascular surgeon removes thrombus or embolus from a carotid, subclavian, or axillary artery through operative exposure, using direct extraction and, when needed, catheter assistance. The procedure addresses an obstructed artery, such as acute limb or cerebral ischemia caused by an arterial clot. It is typically performed in a hospital operating room; the code describes clot removal without a bypass graft.
Report the code when the operative documentation supports clot removal from one of these named arteries and identifies the approach and any catheter use. If the operation includes a bypass graft, compare the corresponding code for thrombectomy with bypass. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 identifies bilateral procedures, paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
