What 35636 covers
A vascular surgeon uses a non-vein graft to route blood from the splenic artery to a renal artery. The operation may be selected to restore renal perfusion when the splenic artery is a suitable source of inflow; the code distinguishes this route from bypasses originating at the aorta or iliac artery. The service is performed in a surgical setting, not as an office procedure.
Report the code for the splenic-to-renal route and non-vein conduit. The operative report should identify the inflow and recipient arteries, graft type, and laterality. The procedure has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and other procedures at 50%. Modifier 50 identifies a bilateral procedure paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

What should the operative report document?
Document the splenic artery as the inflow, the renal artery recipient, the non-vein graft, and the side treated.
How is a bilateral procedure reported?
CMS identifies modifier 50 for bilateral reporting and pays the procedure at 150%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
