What 36465 covers

This service treats venous reflux in one incompetent truncal vein, such as the great saphenous or an accessory saphenous vein. The clinician injects noncompounded foam sclerosant percutaneously and uses ultrasound and compression maneuvers to guide its spread and monitor treatment. Vascular specialists commonly perform it in an office or outpatient setting for patients with symptomatic varicose veins related to truncal reflux.

Report one unit for treatment of one qualifying truncal vein. Documentation should identify the treated vein and extremity, the reflux problem, and the foam treatment performed. Ultrasound guidance and monitoring for this treatment are included. The service has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 results in payment at 150% for bilateral treatment. 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.

36465 billing questions

When should 36465 be used instead of 36466?

Use 36465 when one incompetent truncal vein is treated with noncompounded foam. Use 36466 when multiple incompetent truncal veins are treated.

Is ultrasound guidance separately reported with 36465?

No. Ultrasound guidance and monitoring used to direct and observe the foam treatment are included in 36465.

How many units are reported for one treated vein?

Report one unit for treatment of one qualifying truncal vein. The documentation should identify the treated vein and extremity.

How does 36465 differ from 36470 or 36471?

36465 is for noncompounded foam treatment of an incompetent truncal vein. Codes 36470 and 36471 describe sclerosant treatment of one or multiple other incompetent veins, rather than truncal-vein foam treatment.

How is bilateral treatment handled?

When bilateral treatment is reported with modifier 50, CMS payment is 150% of the single-procedure rate. Multiple procedures in the same session are subject to the standard reduction, with the highest-valued procedure paid in full and others at 50%.

Can an assistant surgeon or co-surgeon be reported?

CMS does not pay an assistant at surgery for this service, and 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.
