About 35511: Subclavian-to-subclavian artery bypass with vein
Reports a vein-graft bypass connecting the subclavian arteries when a vascular surgeon routes blood around subclavian artery obstruction.
A vascular surgeon creates a bypass from one subclavian artery to the other using a vein graft. The operation provides a route for blood around disease affecting subclavian flow and is performed in an operating room. The operative report should identify both arterial connections and the vein conduit; the graft’s destination distinguishes this procedure from bypasses ending in the brachial, axillary, or vertebral artery.
Report 35511 for the completed subclavian-to-subclavian bypass, using the operative findings to confirm the inflow and outflow arteries. CMS assigns a 90-day global period that includes the day-before preoperative visit and 90 days of related postoperative care. If other procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. For a bilateral procedure reported with modifier 50, CMS pays 150%; a single graft connecting arteries on opposite sides should not be mistaken for two bypasses. An assistant at surgery may be paid. Co-surgeons require supporting documentation, and CMS does not permit team surgery for this code.

35511 billing questions
When is 35511 selected instead of 35512?
Select 35511 when the bypass ends in a subclavian artery. Code 35512 describes a bypass from a subclavian artery to a brachial artery.
Does a graft crossing from one side to the other require modifier 50?
The single subclavian-to-subclavian graft is not, by itself, two bilateral bypass procedures. CMS pays 150% for a bilateral procedure reported with modifier 50.
Which visits are included in the global period?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is 35511 paid with another procedure in the same session?
Under the standard multiple procedure reduction, CMS pays the highest-valued procedure in full and other procedures at 50%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; CMS does not permit team surgery for 35511.
What operative details support selection of 35511?
The report should identify the subclavian artery at each end of the bypass and document the vein graft used to connect them.
