What 36471 covers

This service treats multiple incompetent superficial veins in one leg by injecting a sclerosing agent to close the targeted veins. It is commonly performed by a vascular surgeon, interventional radiologist, or other qualified clinician in an office or outpatient setting for patients with varicose veins or related symptoms. The code distinguishes treatment of multiple veins from treatment of a single incompetent vein and from injection treatment directed at spider veins.

Report the service when documentation identifies the treated leg, the multiple incompetent veins addressed, and the injection treatment performed. This is a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral treatment reported with modifier 50, CMS pays at 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are 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.

36471 billing questions

When should 36471 be chosen over 36470?

Use 36471 when multiple incompetent veins in the same leg are treated. Use 36470 when treatment is limited to one incompetent vein.

How does 36471 differ from foam sclerotherapy codes 36465 and 36466?

Those codes describe treatment using non-compounded foam sclerosant. Choose between them and 36471 based on the documented technique and number of veins treated.

Can same-day preoperative or postoperative care be billed separately?

Same-day preoperative and postoperative care is included in the 0-day global period for this procedure.

How is bilateral treatment reported?

When both legs are treated and the service is reported with modifier 50, CMS pays at 150%.

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

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

Can an assistant or co-surgeon be billed for this procedure?

Assistant-at-surgery services are not paid for this code. Co-surgeons and team surgery are 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.
