What 34718 covers
This code covers deployment of an iliac branch endoprosthesis to treat an additional iliac vessel during endovascular aneurysm repair. The branched device is used to exclude an iliac aneurysm while maintaining blood flow into the internal iliac artery when that branch is treated. Vascular surgeons and other physicians performing endovascular repair typically provide the service in a hospital or other facility setting. The additional-vessel service may be performed on the opposite side from the initial repair when bilateral anatomy requires branch devices on both sides.
Report this code with 34717 for each additional vessel treated; 34717 represents the initial vessel. The operative report should identify the vessels treated and document deployment of the additional iliac branch endoprosthesis. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For procedures in the same session, CMS applies the standard multiple-procedure reduction: the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment and co-surgeons are permitted; team surgery is not permitted.

34718 billing questions
When should 34718 be reported instead of 34717?
Use 34717 for the initial iliac vessel treated with an iliac branch endoprosthesis. Report 34718 for each additional vessel treated in the same repair.
Can 34718 be reported without 34717?
No. It represents an additional-vessel service and is reported with 34717 for the initial vessel.
What documentation supports 34718?
Document the additional iliac vessel treated and deployment of the iliac branch endoprosthesis. The operative report should distinguish the additional vessel from the initial vessel reported with 34717.
Should modifier 50 be appended for treatment on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code. Report the initial and additional vessel services as applicable rather than using modifier 50.
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. CMS also permits assistant-at-surgery payment and co-surgeons for this service.
How are other procedures in the same session paid?
CMS applies the standard multiple-procedure reduction: the highest-valued procedure is paid in full, and other procedures in the session are paid at 50%.
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.
