What 35306 covers
Code 35306 represents treatment of an additional artery during an operative session that includes a primary arterial endarterectomy. The surgeon removes obstructive plaque to reopen the artery; a patch may be used when clinically indicated. Vascular surgeons typically perform this work in the operating room for patients with atherosclerotic arterial narrowing. The operative record should identify the additional artery and describe the separate endarterectomy performed there.
Report 35306 only with a qualifying primary procedure; it is not a standalone service. Documentation should support that a distinct additional artery was treated, rather than recounting work already included in the primary procedure. CMS classifies 35306 as an add-on code, and payment is included within the primary procedure’s global period. The claim should pair the add-on with the primary procedure for the main artery treatment.

35306 billing questions
Can 35306 be reported by itself?
No. It is an add-on for endarterectomy of an additional artery and must be reported with a qualifying primary procedure.
What distinguishes 35306 from a primary endarterectomy code?
The primary code reports treatment of the main artery. Code 35306 reports endarterectomy of a separate additional artery during the operative session.
What documentation supports an additional artery unit?
The operative report should identify the additional artery and describe the separate plaque-removal work performed on it.
Is the add-on paid outside the primary procedure’s global period?
No. CMS places payment for 35306 within the primary procedure’s global period.
Should 35306 be reported for patch work on the primary artery?
