What 35305 covers

This code represents open removal of obstructive plaque from a femoral artery to restore blood flow to the leg. Vascular surgeons commonly perform it for atherosclerotic occlusive disease, often when disease affects the common femoral artery. The artery may be closed with a patch as part of the operation. The service is generally performed in a hospital operating room rather than an office setting.

Report the code when the operative work is a femoral artery endarterectomy; the operative note should identify the artery treated, the plaque removal, and any patch closure. A profunda femoris reconstruction involving profundaplasty may point to a different code. Medicare assigns this major surgery a 90-day global period, which includes the day-before preoperative visit and related postoperative care during that period. 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 may be paid; co-surgeon payment requires 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.

How to choose

35304Arterial endarterectomy
Choose 35304 for endarterectomy of an iliac artery; choose 35305 for the femoral artery.
35306Arterial endarterectomy
35306 identifies popliteal artery endarterectomy. The operative report's named arterial site distinguishes it from femoral treatment.
35371Arterial endarterectomy
35371 is for qualifying femoral, profunda, or popliteal endarterectomy that includes profundaplasty; 35305 represents femoral endarterectomy without that defining work.

35305 billing questions

When should this code be chosen over the iliac endarterectomy code?

Use this code when the treated artery is femoral. The iliac code applies when the endarterectomy is performed on an iliac artery.

Is patch closure separately reported?

A patch used to close the artery is included in the endarterectomy service. Document the patch in the operative report.

How is bilateral femoral endarterectomy reported?

Report bilateral work with modifier 50; CMS payment is 150% for the bilateral procedure.

What postoperative care is included?

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

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation.

When might the profundaplasty code be a better fit?

Consider the code for endarterectomy with profundaplasty when the documented operation includes that reconstruction, rather than a femoral endarterectomy alone.

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.
