What 35523 covers

A vascular surgeon uses a vein graft to route blood from the brachial artery to the radial or ulnar artery. The operation may be performed for upper-extremity arterial occlusive disease causing inadequate forearm or hand perfusion. The operative report should identify the brachial inflow artery, the radial or ulnar outflow target, and the vein conduit used. The code describes the bypass reconstruction, not vein harvest by itself.

Select this code when the bypass begins at the brachial artery and ends at a radial or ulnar artery; the documented anastomosis sites distinguish it from other upper-extremity bypass codes. A separate vein harvest may be reported when performed and supported by the record. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose

35522Arterial bypass
35522 describes an axillary-to-brachial bypass. Choose 35523 when the bypass instead runs from the brachial artery to a radial or ulnar artery.
35525Arterial bypass
35525 is for a brachial-to-brachial bypass. For a brachial inflow with radial or ulnar outflow, use 35523.
35500Vein harvest
35500 describes vein harvest for bypass, rather than the arterial bypass reconstruction from the brachial artery to a forearm artery.

35523 billing questions

How do I distinguish this from a brachial-to-brachial bypass?

Use 35523 when the distal target is the radial or ulnar artery. A brachial artery target calls for the brachial-to-brachial code 35525.

Is vein harvest included in this bypass code?

The code describes the bypass using a vein conduit. A separately performed vein harvest may be reported with 35500 when supported by the operative documentation.

What operative details support selection of 35523?

Document the brachial inflow, whether the outflow target is radial or ulnar, and the vein graft used to create the bypass.

How does Medicare handle other procedures performed in the same session?

The highest-valued procedure is paid in full, and other procedures are paid at 50% under the standard multiple-procedure reduction.

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?

Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

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.
