What 34530 covers
This code describes an open surgical connection between veins in a leg. A vascular surgeon may perform the anastomosis during operative reconstruction when the documented procedure is a direct vein-to-vein connection; the operative report should identify the veins joined and the work performed. It is distinct from an operation that repairs or repositions a venous valve, or uses a graft to create a crossover route.
Report the code when the operative documentation supports a lower-extremity venous anastomosis, not merely because venous connections are part of another coded procedure. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 34520Venous bypassFemoral-femoral crossover graft
- Choose 34520 for a crossover vein graft between femoral veins. Choose 34530 when the documented procedure is a direct venous connection in a lower extremity.
- 34501Venous valve repairFemoral vein
- 34501 is for repair of a femoral venous valve. It does not describe joining leg veins.
- 34510Vein valve transpositionLower-extremity valve transfer
- 34510 describes transposition of a venous valve. Use 34530 for a direct lower-extremity venous anastomosis instead.
34530 billing questions
How is this different from a femoral vein crossover graft?
34530 describes a direct lower-extremity vein-to-vein connection. 34520 describes a crossover vein graft between femoral veins, so select based on the operation documented rather than treating the terms as interchangeable.
Should I report 34530 for an anastomosis made during another operation?
The operative report must support a separately reportable lower-extremity venous anastomosis. Do not select 34530 solely because an anastomosis is mentioned as part of another procedure.
Can modifier 50 be used for bilateral work?
Yes. CMS identifies this as a bilateral procedure; reporting with modifier 50 is paid at 150%.
How does Medicare treat another procedure performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction, with payment at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
