What 34471 covers

This service is open removal of thrombus from the femoral vein through an incision in the leg. The surgeon exposes the vein and extracts the clot directly or uses a catheter through the operative exposure. Vascular surgeons typically perform it in a hospital operating room when treating significant deep venous thrombosis that requires operative clot removal rather than anticoagulation alone.

Report the code when the operative report supports femoral-vein thrombectomy through a leg incision; document the treated vein, approach, and clot-removal technique. It has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed 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%. An assistant at surgery is not paid; co-surgeons require supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

34471 billing questions

How is this code distinguished from 34451?

The operative site determines the choice: this code is for femoral-vein thrombectomy through a leg incision, while 34451 is for popliteal-vein thrombectomy through a leg incision.

What documentation supports reporting this code?

The operative report should identify the femoral vein, the leg-incision approach, and removal of thrombus by direct extraction or catheter.

Is related postoperative care included?

Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant surgeon be reported?

Medicare does not pay an assistant at surgery for this code. Co-surgeons are paid only when supporting documentation is provided.

How is bilateral thrombectomy reported?

When the procedure is performed bilaterally, report modifier 50; CMS pays the bilateral procedure at 150%.

What happens when another procedure is performed in the same session?

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

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.
