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

What 33510 covers

A cardiac surgeon uses a vein conduit, commonly the saphenous vein, to route blood around a blocked coronary artery. This code describes a bypass using one venous graft to one coronary target. The operation is performed in a cardiac operating room, usually in a hospital; the code identifies the graft configuration rather than whether the operation is performed on or off pump.

Select the code from the operative report’s account of the conduit type and number of coronary targets bypassed. A single venous graft supports this code; two or more venous grafts point to higher-count codes in the same series. The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate for this descriptor and anatomy.
