What 33514 covers
This code represents coronary artery bypass surgery using venous grafts for five coronary targets. It is generally performed by a cardiothoracic surgeon in an operating room, with vein conduit taken from the patient and connected to bypass narrowed or blocked coronary arteries. The operative report should establish that the bypasses use venous grafts and support the five-target level; arterial grafting changes the code selection.
Select this code from the operative details, not from the number of diseased arteries listed before surgery. The 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate for this 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.

33514 billing questions
How is this code distinguished from 33513 or 33516?
Choose by the documented number of venous bypasses: 33513 is the four-graft level, 33514 the five-graft level, and 33516 six or more.
Can this code be used when an arterial graft is also placed?
No. For a combination of arterial and venous grafting, use the mixed-graft code family, selecting the code that reflects the documented graft combination.
Can modifier 50 be appended for bypasses on both sides?
No. Modifier 50 is inappropriate for this CABG code; report the applicable graft-count code for the operation.
What documentation supports the five-graft level?
The operative report should identify the conduit type and describe the bypasses performed, supporting five venous grafts to coronary targets.
How does the multiple-procedure reduction affect payment?
For procedures performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction.
Is endoscopic vein harvesting reported with this surgery?
Code 33508 describes endoscopic vein harvesting and may be reported with CABG when that harvesting method is performed and documented.
