Cardiac surgery
About 33534: Coronary bypass with two arterial grafts
Reports coronary artery bypass surgery using two arterial grafts to bypass obstructive coronary disease, with the documented graft count determining the code level.
Code 33534 represents coronary artery bypass surgery using two arterial grafts to route blood around obstructive coronary disease. A cardiothoracic surgeon performs the grafting during open cardiac surgery, usually in a hospital operating room. The operative report should identify the arterial grafts and completed bypasses so the documented graft count supports this level.
Report 33534 for the arterial portion when two arterial grafts are performed. If venous grafts are also used, report the applicable 33517–33523 add-on code for their number; 33518 corresponds to two venous grafts. CMS assigns major surgery a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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% reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

33534 billing questions
How does 33534 differ from 33533 or 33535?
Choose among these arterial CABG levels by the number of arterial grafts documented: 33533 is for one, 33534 for two, and 33535 for three.
Can 33534 be reported with a venous CABG code?
Yes. When the operation includes venous grafts as well as the two arterial grafts, report the applicable 33517–33523 add-on code for the number of venous grafts; 33518 corresponds to two.
Is endoscopic vein harvesting included in 33534?
33534 identifies the arterial bypass work. Endoscopic vein harvesting is described separately by 33508 when performed and reportable.
Can modifier 50 be used, and what about surgical assistants?
Modifier 50 is inappropriate for 33534. CMS indicates that an assistant at surgery may be paid, while co-surgeons and team surgery are not permitted.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
