About 35879: Femoral-popliteal bypass vein-patch revision
Reports operative revision of a femoral-popliteal arterial bypass using a vein patch, commonly to address narrowing at the bypass or anastomosis.
Code 35879 describes revision of a lower-extremity arterial bypass in the femoral-popliteal territory using a vein patch. The vascular surgeon revises the bypass or its junction with the artery and uses vein tissue to patch the repair, often when narrowing limits flow. The service is typically performed in an operating room for a patient with a prior femoral-popliteal bypass and a documented graft or anastomotic problem.
Select the code based on bypass territory and patch material: this code represents the femoral-popliteal territory with a vein patch, not a more distal bypass or a nonautogenous patch. The operative report should identify the bypass territory, the site and work of the revision, and use of vein for the patch; document any thrombectomy performed. This major surgery has a 90-day global period that includes the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

35879 billing questions
How does 35879 differ from 35881?
Both describe lower-extremity bypass revision with a vein patch. Choose 35879 for the femoral-popliteal territory and 35881 for the more distal femoral-tibial or femoral-peroneal territory.
When is a nonautogenous patch code more appropriate?
Use the corresponding nonautogenous-patch code when the bypass revision uses patch material other than the patient's vein. The operative report should establish the material used.
How does 35879 differ from 35876?
35879 identifies femoral-popliteal bypass revision using a vein patch. Consider 35876 when the operation is graft thrombectomy with revision rather than the vein-patch revision represented by 35879.
What should the operative report document?
Document the bypass territory, the location and extent of the revision, and use of a vein patch. Describe any thrombectomy performed so the service can be distinguished from thrombectomy with revision.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days.
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.
