Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 33533 covers

A cardiac surgeon uses an arterial conduit to route blood around a coronary artery blockage. A common example is an internal thoracic artery graft to the left anterior descending artery. The operation is typically performed in a hospital operating room for a patient with coronary artery disease requiring surgical revascularization. This code represents the bypass operation, not simply conduit harvesting.

Select this code when the operation uses one arterial graft; use the arterial CABG family’s higher-level codes when more arterial grafts are used. If venous grafting is also performed, the applicable combined arterial-venous code is reported with the arterial CABG code. The operative report should identify the graft type and number, bypassed vessels, and completed procedure. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate for this code. Assistant-at-surgery services may be paid; co-surgeons and team surgery are not permitted.
