What 33523 covers
During coronary artery bypass surgery, the surgeon uses venous conduits alongside arterial conduits to route blood around obstructed coronary arteries. This code represents the venous-graft portion when six or more venous grafts are used. It applies to CABG performed by a cardiac surgeon in an operating room. The primary arterial CABG code identifies the number of arterial grafts, while 33523 captures the venous-graft count.
Select the code from the operative report’s documented conduit and graft counts, rather than simply the number of coronary targets or distal connections. Report 33523 only with the appropriate primary arterial CABG code, 33533–33536, selected according to the arterial-graft count. The operative note should identify the conduits and support six or more venous grafts. CMS classifies 33523 as an add-on code: it is billed only with a primary procedure, and its payment falls within that procedure’s global period.
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.

33523 billing questions
Which primary CABG code is reported with 33523?
Report it with the appropriate arterial CABG code from 33533–33536. The primary code reflects the arterial-graft count.
Does six or more refer to the arterial or venous grafts?
It refers to the venous grafts. The arterial-graft count is represented by the primary CABG code.
Can 33523 be reported by itself?
No. It is an add-on code billed only with a primary procedure, and CMS payment is within that procedure’s global period.
How does 33523 differ from 33516?
33523 represents six or more venous grafts in CABG that also uses arterial grafting. 33516 is for six or more venous grafts without arterial grafting.
What documentation supports 33523?
The operative report should identify the arterial and venous conduits and document six or more venous grafts.
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.
