What 35501 covers

A vascular surgeon uses a vein graft to create a new blood-flow route between carotid artery segments on the same side of the neck. The operation may be considered when disease, injury, or another lesion prevents adequate flow through the native carotid segment. It is generally performed in a hospital operating room. The operative report should identify the side, the carotid segments joined, the graft material, and the reason for bypass.

Report this code for the ipsilateral carotid-to-carotid configuration; a bypass connecting different named arteries or the opposite carotid side is represented by a different code. If a vein is separately harvested for the graft, review the applicable harvest code and documentation. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

35501 billing questions

How does this differ from 35509?

35501 is for a carotid-to-carotid bypass on the same side. 35509 describes a bypass between the right and left carotid arteries.

What details should the operative report support?

Document the bypass indication, laterality, carotid segments connected, and use of a vein graft. These details distinguish the ipsilateral configuration from other carotid bypass routes.

Can the vein harvest be reported separately?

When a vein is separately harvested for the bypass, review 35500 for the harvest and document the work performed. The bypass code describes the carotid reconstruction.

How is bilateral performance reported?

When the procedure is performed bilaterally, modifier 50 applies under the CMS bilateral rule; payment is at 150%. The operative documentation should establish both sides.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

Can an assistant or co-surgeon be paid?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

Where these rates come from

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.
