What 35701 covers
A vascular surgeon exposes and examines a neck artery to investigate a suspected vascular problem, such as possible injury or abnormality. The service involves operative exploration rather than imaging or a limited bedside assessment. It is reported when the surgeon explores the artery and does not proceed with surgical repair; if a definitive arterial procedure is performed, report the procedure that describes that treatment instead of separately reporting the exploration.
The operative report should identify the neck artery, the reason for exploration, the operative findings, and whether repair or another definitive procedure was performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. 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.
