About 33518: Coronary bypass with two venous grafts
Add-on reporting for coronary bypass surgery using two venous grafts together with one or more arterial grafts.
This add-on represents the venous-graft portion of coronary artery bypass surgery when the operation also uses an arterial graft. A cardiac surgeon typically performs the bypass in a hospital operating room, using venous conduit such as saphenous vein to route blood around coronary artery blockages alongside an arterial conduit such as an internal mammary artery. The code is selected for two venous grafts; it does not represent two total grafts or the arterial graft count.
Report 33518 with the primary arterial CABG code that reflects the number of arterial grafts. The operative report should identify the arterial and venous conduits and document the number of each used. As an add-on, 33518 is billed only with a primary procedure and is paid within that procedure’s global period; it is not a stand-alone CABG report. The venous graft count determines this add-on level, while the arterial graft count determines the primary code.

Both are mixed arterial-and-venous CABG add-ons. Choose 33519 when three venous grafts are documented rather than two.
No office rate

No office rate
33533 is the primary CABG code for one arterial graft. It does not capture the two venous grafts represented by add-on code 33518.

33518 billing questions
Does 33518 mean two total bypass grafts?
No. It represents two venous grafts used with arterial grafting. The primary arterial CABG code reflects the arterial graft count.
Which primary code is reported with 33518?
Report the arterial CABG code for the number of arterial grafts, such as 33533 for one arterial graft or 33534 for two.
How does 33518 differ from 33511?
33518 is for two venous grafts used with arterial grafting. 33511 represents two venous grafts without the arterial-graft combination represented by 33518.
What documentation supports the two-graft level?
The operative report should identify the graft types and document two venous grafts, along with the arterial grafting that supports the primary CABG code.
Can 33518 be reported by itself?
No. It is an add-on code reported with the primary arterial CABG procedure and is paid within that procedure’s global period.
