Vascular surgery
About 35606: Carotid-to-subclavian arterial bypass
Open carotid-subclavian bypass with a non-vein conduit reroutes blood flow when proximal subclavian obstruction limits arm or vertebral circulation.
A vascular surgeon creates a new route from the carotid artery to the subclavian artery using a non-vein conduit, commonly a prosthetic graft. The operation can restore flow with proximal subclavian occlusive disease causing arm ischemia or vertebral steal, or preserve circulation when the subclavian origin must be covered during aortic repair. It is generally performed in a hospital operating room.
Report this code for the completed carotid-to-subclavian bypass using a non-vein conduit; a vein conduit follows a different code. The operative report should identify the inflow and outflow arteries, conduit, laterality, and reason for revascularization. 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 is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

35606 billing questions
How does this code differ from 35506?
Both describe a carotid-to-subclavian bypass, but 35606 is for a non-vein conduit. Use 35506 when the bypass is performed with a vein conduit.
What should the operative report document?
Document the carotid inflow, subclavian outflow, conduit type, laterality, and indication. These details establish the route and distinguish a non-vein bypass from a vein bypass or a different arterial reconstruction.
How is bilateral reporting handled?
For bilateral procedures, report modifier 50; CMS pays the bilateral procedure at 150%. Document the work performed on both sides.
What happens when another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedure or procedures are paid at 50%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
