CPT code 35536: Arterial bypass, splenorenal vein graft2026 Medicare rate & RVUs

Medicare pays $1,535.44 for 35536 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 35536 covers

A vascular surgeon uses a vein graft to create an arterial route from the splenic artery to the renal artery. The operation may be considered for renal artery occlusive disease when the splenic artery is suitable as the source of blood flow. This is an open vascular reconstruction, not a splenic-vein-to-renal-vein shunt used to manage portal hypertension. The operative report should identify the arterial inflow and outflow, the vein conduit, and the bypass performed.

Report this code when the documented bypass connects the splenic and renal arteries using a vein graft; the chosen inflow and outflow distinguish it from other renal bypass configurations. 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 procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 applies to a bilateral procedure, paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
