About 35685: Bypass patency patch angioplasty
An add-on for a bypass operation when a patch angioplasty is performed to support graft patency, such as with a profunda outflow repair.
This add-on represents patch angioplasty performed as an adjunct to an arterial bypass to improve or maintain graft outflow and patency. A vascular surgeon may use it when the artery at the bypass outflow requires enlargement; profundaplasty is a typical example. The patch is part of the open operation, not a separate later procedure. It is generally encountered in facility-based vascular surgery, including lower-extremity revascularization for significant arterial disease.
Report 35685 only with the primary bypass procedure when the operative note supports a distinct patch angioplasty for graft patency. Documentation should identify the bypass, the artery treated, and the patch work performed; a routine anastomosis alone does not establish this service. This is an add-on code, not a standalone bypass code. Medicare pays it within the primary procedure's global period, so it is reported with that primary procedure rather than as an independent service.

35685 billing questions
When should 35685 be reported with a bypass?
Report it when the surgeon performs a patch angioplasty as an adjunct to the bypass to support graft patency. The operative note should describe the artery patched and the additional patch work.
Can 35685 be billed by itself?
No. It is an add-on code and must be reported with a primary bypass procedure.
How is 35685 different from 35686?
35685 represents a patch angioplasty for graft patency. 35686 represents a distal arteriovenous fistula used to support bypass patency, a different adjunct technique.
Is a patch included in the primary bypass code?
A routine bypass anastomosis does not support separate reporting of 35685. Report the add-on when documentation shows the distinct patch angioplasty performed for graft patency.
What documentation supports 35685?
The operative report should identify the bypass and the artery receiving the patch, and describe the patch angioplasty as an adjunct to maintain or improve graft patency.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
