CPT code 34711: Endograft extension, delayed, additional vessel2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 34711 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 34711 covers

This code captures delayed placement of an additional proximal or distal endograft extension in a vessel after an endovascular aortic or iliac repair. The intervention extends the existing repair when another vessel requires an extension; it is not the code for an extension placed during the initial repair. Vascular surgeons and endovascular specialists typically perform the procedure in an operating room or hybrid suite, using imaging to guide device placement.

Report 34711 for each additional vessel beyond the first vessel represented by 34710. The record should identify the prior repair, the vessels treated, the delayed extension placement, and which vessel is the first versus each additional vessel. As an add-on code, 34711 must be billed with a primary procedure and is paid within that procedure's global period. The code cannot stand alone; pair it with the applicable primary procedure and the first-vessel code when multiple vessels are treated.
