What 33536 covers

This code describes coronary artery bypass grafting with four or more arterial grafts. Cardiothoracic surgeons perform the operation, generally in a hospital operating room, to revascularize coronary arteries affected by obstructive disease. Arterial conduits may include an internal thoracic artery or a radial artery. The operative report should identify the conduits used and the number of arterial bypass grafts performed.

Select this code based on the arterial graft count, not the combined number of arterial and venous grafts. When venous grafts are also used, report the appropriate venous-graft add-on code with the arterial CABG code. 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 other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment may be available; co-surgeon and team-surgery payment are not permitted 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.

33536 billing questions

How many grafts qualify for this code?

Use it when the operative documentation supports four or more arterial bypass grafts. For fewer arterial grafts, select the corresponding lower-count arterial CABG code.

Do venous grafts count toward the four-graft threshold?

No. Select the arterial CABG code by the number of arterial grafts; report the appropriate venous-graft add-on code when venous grafts are also used.

What documentation supports reporting this code?

The operative report should identify the arterial conduits and document the number of arterial bypass grafts performed. It should also distinguish any venous grafts used during the operation.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and related postoperative care for 90 days after surgery are included in this code's global period.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment may be available. Co-surgeon and team-surgery payment are not permitted for this 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.
