35650 Arterial bypass Medicare reimbursement rates in Idaho

An axillary-to-axillary bypass creates an extra-anatomic route between the right and left axillary arteries, typically using a prosthetic conduit tunneled beneath the skin across the chest. A vascular surgeon may perform it to reroute blood around an obstructed proximal inflow vessel, such as in subclavian artery disease, when circulation to an arm needs restoration. The operation is generally performed in a hospital operating room. The operative report should identify both arterial anastomoses, the conduit and tunnel, and the reason for the bypass.

Report 35650 when the bypass connects axillary artery to axillary artery using a conduit other than vein. Choose a neighboring bypass code by the documented inflow and outflow arteries, not simply the incision or disease location. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. When modifier 50 is appropriate for a bilateral service, CMS pays 150%; the two ends of this single crossover graft alone are not two separate bypasses. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
