What 33511 covers

This code describes coronary artery bypass surgery in which vein is used to create two bypasses around obstructed coronary arteries. The surgeon typically uses saphenous vein harvested from the leg and performs the bypass during open-heart surgery in a hospital operating room. The operative report should identify the bypassed coronary targets and the conduit used for each. If vein is harvested endoscopically, the harvest service may be reported separately with 33508 when supported by the operative documentation.

Select the code by the number of coronary bypasses performed with venous grafts; do not base the count solely on how much vein was harvested. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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. The graft count is not a bilateral service, so modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

33511 billing questions

How does 33511 differ from 33510 and 33512?

These codes distinguish the number of coronary bypasses performed with vein: 33510 represents one, 33511 two, and 33512 three.

What if the operation uses both vein and an arterial graft?

Use the mixed-conduit coding structure rather than 33511 alone. Code 33518 represents two venous grafts when reported as an add-on to the appropriate arterial CABG code.

Can endoscopic vein harvesting be reported separately?

Code 33508 may be reported for endoscopic vein harvest performed for CABG when the operative documentation supports that service.

What documentation supports reporting two venous grafts?

The operative report should identify the coronary targets bypassed and show that two bypasses used venous conduits. Vein length or the amount harvested alone does not establish the bypass count.

Is modifier 50 appropriate, and what surgical modifiers are relevant?

Modifier 50 is inappropriate because the code counts coronary bypasses, not a bilateral service. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

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.
