What 35600 covers

During coronary artery bypass grafting, the surgeon exposes and harvests one segment of an artery in the arm for use as a bypass conduit. The radial artery is a common example. This is an open harvest, typically performed by a cardiac surgeon in the operating room as part of the CABG operation; it is not a standalone diagnostic or therapeutic service.

Report the code only with a primary CABG procedure, and select it when the operative record supports open harvest of one upper-extremity artery segment. Documentation should identify the harvested vessel, the open technique, the segment obtained, and its use for coronary bypass. CMS classifies this as an add-on code: it is billed only with a primary procedure and paid within that procedure’s global period. The CABG procedure remains the primary service; this code captures the additional conduit-harvest work.

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.

How to choose

33509Artery harvest
Choose 35600 for open upper-extremity artery harvest; 33509 represents endoscopic harvest of the artery for CABG.
33533Arterial CABG
33533 reports the CABG service using a single arterial graft. 35600 is an add-on for qualifying open harvest of an arm artery segment.
33534Arterial CABG
33534 identifies CABG using two arterial grafts. It is a primary bypass code, whereas 35600 captures the open harvest of one upper-extremity artery segment.

35600 billing questions

When should this code be selected instead of 33509?

Use 35600 for open harvest of an upper-extremity artery segment for CABG. Code 33509 describes endoscopic harvest of that artery.

Can 35600 be reported by itself?

No. It is an add-on code and must be reported with a primary CABG procedure.

What documentation supports the code?

The operative report should establish that an upper-extremity artery was harvested by open technique, identify the vessel and segment, and document its use as a coronary bypass conduit.

How does the CMS global-period rule affect payment?

CMS pays this add-on within the global period of the primary procedure. It must be linked to the CABG procedure rather than billed as an independent service.

Does the code describe multiple harvested segments?

The code is for one segment. The operative documentation should support the segment reported; do not use it to characterize a different harvest technique.

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.
