What 35304 covers
This open vascular procedure clears obstructive material from an artery to restore its channel. The surgeon exposes the vessel, removes the obstructing material, and may use a patch to close or enlarge the treated segment. Vascular surgeons typically perform it in an operating room, often for symptomatic or flow-limiting arterial disease. Code selection depends on the specific artery and the procedure performed; use the code whose CPT descriptor matches the operative site.
Report one unit for the treated artery when the documentation identifies the vessel and supports open rechanneling. The operative report should describe the target artery, the removal of obstructive material, and any patch repair. A patch used as part of the endarterectomy is included in the service. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

35304 billing questions
How do I choose this code over another 3530x code?
Match the operative artery to the specific CPT descriptor. The shared short descriptor is not enough to distinguish the artery-level codes.
Is patch repair separately reported?
A patch used to close or enlarge the artery as part of the endarterectomy is included in this service.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can I report modifier 50 for bilateral work?
CMS identifies this as a bilateral procedure; modifier 50 is paid at 150% when bilateral reporting is appropriate.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
