What 33894 covers

This service repairs disease of the descending thoracic aorta or aortic arch by delivering a branched endograft through vascular access and positioning it to exclude the diseased aortic segment while preserving flow through one branch vessel. Vascular or cardiothoracic surgeons typically perform it in an operating room or hybrid endovascular suite for conditions such as thoracic aortic aneurysm or dissection involving an arch branch. The branch-preserving graft configuration distinguishes this procedure from standard thoracic endografting.

Report the code when the documented repair uses a branched endograft involving one branch vessel; the operative report should support the aortic treatment and branch configuration. Associated radiological supervision and interpretation are included in the procedure. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are 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.

How to choose

33895Coarctation stent repair
Choose 33894 when the branched endograft involves one branch vessel; 33895 describes the two-branch-vessel configuration.
33880Thoracic endovascular repair
33880 describes standard thoracic endograft repair without coverage of the left subclavian origin, rather than repair with a branched graft involving one branch vessel.
33881Thoracic endograft
33881 describes standard thoracic endograft repair involving coverage of the left subclavian origin; 33894 is selected for the one-branch branched-endograft configuration.
33882Thoracic endograft
33882 describes thoracic endovascular repair using a multiple-component system, not the one-branch branched-endograft service reported with 33894.

33894 billing questions

How is 33894 distinguished from 33895?

33894 is for a branched endograft repair involving one branch vessel. Use 33895 for the sibling configuration involving two branch vessels.

Are radiological supervision and interpretation separately reported?

No. The associated radiological supervision and interpretation are included in this repair.

Can modifier 50 be used?

No. The CMS bilateral adjustment does not apply to this service, and modifier 50 is inappropriate.

What supports reporting 33894?

The operative report should describe the descending thoracic aortic or arch repair and establish that the branched endograft involves one branch vessel.

How are other same-session procedures paid?

The highest-valued procedure is paid in full; other procedures performed in the same session are subject to the standard multiple-procedure reduction.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. 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.
