CPT code 34530: Vein anastomosis, lower extremity2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 34530 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
