Vascular surgery
About 35512: Subclavian-to-brachial artery bypass
Reports surgical graft bypass from the subclavian artery to the brachial artery to restore blood flow in an ischemic upper extremity.
A vascular surgeon uses a graft to route blood from the subclavian artery to the brachial artery, bypassing an obstructed or diseased arterial segment. The operation is generally performed in a hospital operating room for upper-extremity arterial insufficiency when this inflow and outflow route is selected. The graft may use an appropriate conduit documented in the operative report.
Report 35512 when the bypass runs specifically from the subclavian artery to the brachial artery; the documented origin and destination distinguish it from other upper-extremity bypass codes. The operative note should identify the indication, bypass route, graft, and work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
