Cardiac surgery
About 33516: Coronary bypass with six or more vein grafts
Reports coronary artery bypass surgery using six or more venous grafts, without an arterial graft counted as part of this venous-only code.
A cardiac surgeon uses this code for coronary artery bypass surgery in which six or more venous grafts are placed to route blood around obstructed coronary arteries. A common setting is an operating room during surgery for multivessel coronary artery disease. The surgeon’s operative report should identify the conduits used and the number of venous bypass grafts performed; the count is not the number of veins harvested.
Select this code for six or more venous grafts when the bypass uses venous grafts only. When arterial and venous grafts are both used, report the appropriate arterial CABG primary code with the corresponding venous-graft add-on code instead. The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

33516 billing questions
How many grafts qualify for this code?
Report it when the operation places six or more venous bypass grafts. Use the operative report to support the graft count.
Should this code be used when arterial and venous grafts are both performed?
No. For a combined arterial-and-venous bypass, report the appropriate arterial CABG primary code with the venous-graft add-on code matching the venous graft count.
Can vein harvesting be reported with the bypass?
Endoscopic vein harvesting may be reported with CABG when that service is performed and separately reportable. The bypass code itself represents the grafting operation, not the harvest technique.
Can modifier 50 be used?
No. CMS identifies bilateral adjustment as inappropriate for this code.
How does the multiple-procedure payment rule affect this code?
When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and other procedures at 50%.
What does the global period include, and may an assistant be reported?
The 90-day global includes the day-before preoperative visit and related postoperative care during the 90 days after surgery. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
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.
