What 35565 covers
A vascular surgeon uses a vein conduit to create a new path for blood between an iliac artery and a femoral artery, bypassing a diseased or blocked segment. The operation is typically performed in a hospital or other surgical facility for lower-extremity revascularization, often in patients with significant peripheral arterial disease. The code identifies the bypass by its arterial endpoints and vein conduit, not simply by the diagnosis or the location of the blockage.
The operative report should establish the iliac inflow, femoral outflow, use of a vein graft, and the side or sides treated. CMS classifies this as major surgery with a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
