Cardiac surgery

About 33510: Single venous coronary bypass graft

Report this code for coronary artery bypass surgery using one venous graft to bypass one coronary target, without an arterial bypass graft.

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.

33517

Combined CABG

No office rate

33533 describes a single arterial bypass graft. This code describes a single venous bypass graft.

33510 billing questions

How is this code distinguished from 33511?

This code represents one venous coronary bypass graft. Code 33511 represents two venous grafts; use the operative report’s documented graft count.

Does the number of harvested veins determine the code?

Choose the CABG code based on the bypass graft configuration and coronary targets documented in the operative report, not simply the amount of vein harvested.

Can vein harvesting be reported separately?

Endoscopic vein harvesting has a separate code, 33508. The operative documentation should identify the harvesting method and the CABG procedure performed.

Can modifier 50 be used for a bypass on both sides?

No. Bilateral adjustment is inappropriate for this descriptor and anatomy.

How are multiple procedures and postoperative visits handled?

The 90-day global period includes the day-before preoperative visit and related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%.

May an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeons and team surgery are not permitted for this code.
