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

What 35509 covers

This operation uses a vein conduit to connect one carotid artery to the carotid artery on the opposite side of the neck, creating a route for blood flow around a diseased or obstructed segment. A vascular surgeon typically performs the reconstruction in an operating room. The operative report should identify both carotid endpoints and the vein graft so the cross-neck bypass can be distinguished from a bypass on one side or a reconstruction involving another artery.

Select this code when the documented bypass connects contralateral carotid arteries using a vein graft. Documentation should support the conduit, the donor and recipient vessels, and the completed bypass. Medicare treats the service as major surgery with a 90-day global period, including the day-before preoperative visit and related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 for a bilateral procedure 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.
