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

What 35663 covers

A vascular surgeon creates a new route for blood flow between iliac arteries, bypassing a diseased or unusable segment. The graft is made from a nonvein conduit, commonly a synthetic graft. The operation is performed in a surgical setting for patients who need iliac revascularization; the documented origin and destination arteries distinguish this service from bypasses to the aorta, femoral artery, or another vascular territory.

Select the code based on the iliac-to-iliac route and nonvein conduit, not on the diagnosis alone. The operative report should identify the inflow and outflow arteries, bypass course, and graft material. 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 the same session, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 bilateral reporting 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.

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.
