About 33871: Transverse aortic arch graft under hypothermic arrest
Reported when an open operation replaces the transverse aortic arch with a graft and uses hypothermic circulatory arrest.
A cardiac surgeon uses this code for open graft replacement of the transverse aortic arch during hypothermic circulatory arrest, typically with cardiopulmonary bypass. The operation may address an arch aneurysm or aortic dissection involving the transverse arch. It is performed in an operating room, generally in a hospital setting; the operative report should identify the arch segment replaced and describe the graft reconstruction and use of hypothermic arrest.
Select the code from the operation actually performed, distinguishing transverse arch replacement from a hemiarch repair or a repair specifically for hypoplastic arch. The code has a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment may be available. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.

33871 billing questions
How does this differ from a hemiarch graft?
Use 33871 for transverse arch graft replacement with hypothermic circulatory arrest. Code 33866 describes aortic hemiarch graft work, a more limited extent of arch replacement.
When would 33853 be considered instead?
Code 33853 describes repair of a hypoplastic aortic arch with bypass. Choose based on the documented operation and indication, rather than treating it as interchangeable with transverse arch graft replacement.
Are related postoperative visits separately reported?
Related postoperative care during the 90-day global period is included. The day-before preoperative visit is also included.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, and team surgery is not permitted for this code.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full; other procedures in the session are subject to the standard 50% multiple-procedure reduction.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
