What 33519 covers

This add-on code identifies the venous portion of a combined coronary artery bypass operation when three venous grafts are used along with arterial grafting. A cardiothoracic surgeon typically performs the bypass in an operating room, using arterial conduits such as an internal thoracic artery and venous conduits such as saphenous vein. The code represents the three venous grafts, not the arterial graft count or the total number of bypass grafts.

Select this code from the number of venous grafts documented in the operative report, and report it with the primary arterial CABG code that reflects the arterial graft count. The record should support the conduits and grafts used. This is an add-on code: it is billed only with a primary procedure and is paid within that procedure's global period. It is not a standalone CABG code.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

33518CABG grafts
Use 33518 when the combined CABG includes two venous grafts; 33519 represents three.
33521CABG grafting
Use 33521 when the combined CABG includes four venous grafts; 33519 represents three.
33512Coronary bypass
33512 describes three venous grafts in a vein-only CABG. 33519 is the venous add-on for a procedure that also includes arterial grafting.
33535Arterial CABG
33535 represents three arterial grafts, not three venous grafts. In a combined procedure, 33535 may be the primary code paired with 33519 when the documented counts support both.

33519 billing questions

Which primary code is reported with 33519?

Report the arterial CABG code that matches the number of arterial grafts, such as 33533 for one arterial graft or 33534 for two. Code 33519 captures the three venous grafts.

Does 33519 mean three grafts total?

No. It represents three venous grafts in a combined arterial-and-venous bypass operation; the arterial graft count is represented by the primary CABG code.

How is 33519 different from 33512?

33519 is for three venous grafts used with arterial grafting. 33512 describes a three-vein-graft CABG without the arterial-grafting combination represented by 33519.

Can 33519 be billed by itself?

No. It is an add-on code and must be reported with the appropriate primary arterial CABG procedure. CMS pays it within that primary procedure's global period.

What documentation supports the three-graft level?

The operative report should identify the venous grafts used and support that three venous grafts were placed. It should also document the arterial grafting represented by the separately reported primary code.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
