What 35875 covers

This code describes open surgical removal of clot from a vascular graft without revision of the graft itself. A typical case is an occluded arterial bypass graft requiring operative exposure and clot extraction to restore flow. Vascular surgeons generally perform the procedure in a hospital operating room or another surgical facility. This code is for grafts other than hemodialysis access; dialysis access thrombectomy has its own code family.

Select the code when the operative report supports clot removal from the graft and does not describe graft revision. Documentation should identify the graft and describe the thrombectomy performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted; 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.

35875 billing questions

How does 35875 differ from 35876?

Use 35875 for clot removal from a vascular graft without graft revision. When the surgeon also revises the graft, consider 35876.

Can 35875 be used for a hemodialysis access thrombectomy?

No. This code is for vascular grafts other than dialysis access. Open thrombectomy of a dialysis access without revision is represented by 36831; with revision, consider 36832.

What documentation supports 35875?

The operative report should identify the graft and describe surgical clot removal. It should support that the graft was not revised.

Does modifier 50 apply?

No. CMS identifies bilateral adjustment as inappropriate for this code.

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

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

Can an assistant or co-surgeon be reported?

CMS restricts assistant-at-surgery payment for this code. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
