What 35500 covers
A vascular surgeon harvests a segment of vein from the arm for use as an autologous conduit in an arterial bypass. Arm vein, such as cephalic or basilic vein, may be selected when suitable leg vein is unavailable or insufficient. The work is performed as part of the operative treatment, commonly during a lower-extremity bypass for arterial disease.
Report 35500 only with the primary bypass procedure; it is not a stand-alone service. The operative report should identify the upper extremity vein harvested and document its use in the bypass. CMS treats this as an add-on code, with payment falling within the primary procedure’s global period. The bypass code describes the reconstruction, while 35500 accounts for the additional vein-harvesting work.

35500 billing questions
Can 35500 be reported by itself?
No. It is an add-on for harvesting upper extremity vein and must be reported with the primary bypass procedure.
When is 35500 preferred over 35572?
Use 35500 when the harvested conduit comes from the upper extremity. Code 35572 describes harvest of femoral vein instead.
What documentation supports 35500?
The operative report should identify the arm vein harvested and show that it was used as conduit for the bypass.
Is the bypass itself included in 35500?
No. Report the applicable primary bypass code as well; 35500 represents the additional upper extremity vein harvest.
How does the global period affect payment?
CMS treats 35500 as an add-on paid within the primary bypass procedure’s global period.
