CPT code 35883: Graft revision, femoral anastomosis, synthetic graft2026 Medicare rate & RVUs

Medicare pays $1,083.53 for 35883 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 35883 covers

A vascular surgeon uses this code for open revision of the connection between a femoral artery and a synthetic lower-extremity bypass graft. A typical reason is narrowing at the graft-to-artery junction, such as stenosis associated with intimal hyperplasia. The procedure is performed in an operating room; it is distinct from simply exploring a limb vessel or removing clot from a graft without revising the connection.

Report this code when the operative record supports revision of a femoral anastomosis involving a nonautogenous graft; a vein graft uses a different code. Documentation should identify the graft material, anastomosis site, the problem treated, and the revision performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

How to choose

35884Graft revisionAutogenous vein at femoral anastomosis

Both address a femoral bypass anastomosis, but 35884 is selected for an autogenous vein graft; this code is for a nonautogenous graft.

35879Bypass revisionFemoral-popliteal, vein patch

35879 describes lower-extremity bypass revision with vein patch angioplasty. Select based on the documented procedure rather than treating it as a graft-material variant of this code.

35881Bypass revisionVein interposition, no thrombectomy

35881 describes bypass revision using segmental vein interposition. This code instead identifies revision of a femoral anastomosis involving a nonautogenous graft.

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.
