What 35311 covers

This code represents open removal of obstructive plaque from the brachiocephalic trunk through a thoracic incision; patch closure, if performed, is part of the service. A vascular or cardiothoracic surgeon typically performs the operation in a hospital operating room for clinically significant trunk disease affecting blood flow to the head or right upper extremity. The operative report should identify the brachiocephalic trunk, the thoracic approach, and the endarterectomy performed.

Report the code for the specified vessel and approach, not for a neck-incision endarterectomy of the carotid, vertebral, or subclavian arteries. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. For a bilateral service reported with modifier 50, payment is at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

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.

35311 billing questions

How is this code distinguished from 35301?

This code is for the brachiocephalic trunk approached through a thoracic incision. Code 35301 covers endarterectomy of the carotid, vertebral, or subclavian artery through a neck incision.

Does patch closure support a separate code?

No. Patch closure, when performed as part of this endarterectomy, is included in the service.

What documentation supports reporting this code?

The operative report should identify the brachiocephalic trunk as the treated vessel and document the thoracic approach and plaque-removal procedure.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

How are multiple procedures in the same session paid?

The highest-valued procedure is paid in full, and other procedures in the same session are paid at 50%. A bilateral service reported with modifier 50 is paid at 150%.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is 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.
