What 36473 covers

This code covers percutaneous treatment of an incompetent lower-extremity vein using a catheter that mechanically disrupts the vein lining while delivering a sclerosant. It is used for superficial venous reflux, such as in a saphenous vein, and is typically performed by a vascular surgeon or another clinician trained in endovenous vein procedures in an office vein center or facility. Imaging guidance and monitoring during the treatment are included in the service.

Report 36473 for the first vein treated by this method; report 36474 for each additional vein treated in the same extremity. Documentation should identify the treated vein, the venous incompetence, the mechanochemical method, and any additional vein treated. CMS assigns 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%. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery services are restricted; 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.

36473 billing questions

When should 36473 be selected instead of 36475 or 36478?

Use 36473 when the vein is treated with mechanochemical catheter treatment. Codes 36475 and 36478 describe radiofrequency and laser ablation, respectively.

How is treatment of another vein reported?

Report 36473 for the first vein and 36474 for each additional vein treated in the same extremity. The record should distinguish the veins treated.

Can imaging guidance be billed separately?

Imaging guidance and monitoring for the mechanochemical treatment are included in 36473.

How is bilateral treatment reported?

CMS identifies this as a bilateral procedure: report modifier 50 for bilateral treatment, which is paid at 150%.

Does the procedure have a postoperative global period?

It has a 0-day global period. Same-day preoperative and postoperative care is included.

Can an assistant or co-surgeon be reported?

CMS restricts payment for an assistant at surgery. 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.
