What 35303 covers

This open vascular operation removes obstructive material from an artery to restore the vessel’s lumen and improve blood flow. Vascular surgeons typically perform it in a hospital operating room for clinically significant arterial narrowing, such as atherosclerotic disease associated with limb ischemia. The operative approach and treated artery are central to identifying the correct code within the 35301–35306 family.

Report 35303 when the documented operation matches its specific billing code descriptor; do not choose among sibling codes based on disease severity alone. The operative report should identify the artery and treated segment, the obstructive disease, and the work performed to restore flow. 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 the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; 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.

How to choose

35301Arterial endarterectomy
Both codes describe arterial rechanneling procedures. Compare the operative artery and segment with each code’s full billing code descriptor rather than choosing by disease severity.
35304Arterial endarterectomy
This is a neighboring family code, not an interchangeable level based on the degree of narrowing. The operative report’s documented artery and treated segment guide code selection.

35303 billing questions

How do I choose 35303 over a nearby code in this family?

Use the billing code descriptor that matches the artery and segment documented in the operative report. The procedure’s severity alone does not determine which family code applies.

What documentation supports reporting 35303?

Document the treated artery and segment, the obstructive disease, and the operative steps used to restore the arterial lumen and blood flow.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

How is 35303 handled when another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures are paid at 50% under the standard multiple procedure reduction.

Can I report modifier 50 for bilateral treatment?

Yes. CMS identifies this as a bilateral procedure; reporting with modifier 50 is paid at 150%.

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.
