What 36474 covers

This add-on represents catheter-based mechanochemical ablation of an additional incompetent vein, using mechanical action together with a sclerosant to close the treated vein. It is used for venous reflux treatment, including treatment of superficial truncal veins, and is typically performed by a vascular surgeon, interventional radiologist, or vein specialist in an office or outpatient procedural setting. The additional vein is treated through a separate access site in the same extremity as the first vein.

Report 36474 only with the primary mechanochemical ablation code 36473; it is not a stand-alone service. Documentation should identify the treated veins, extremity, separate access sites, and the mechanochemical technique. CMS treats this add-on as paid within the primary procedure’s global period. For a bilateral procedure reported with modifier 50, CMS pays at 150%.

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

36473Vein ablation
36473 reports mechanochemical treatment of the first vein. Use 36474 for an additional vein in the same extremity through a separate access site.
36476Vein ablation
Both are additional-vein codes, but 36476 describes radiofrequency ablation; 36474 describes mechanochemical ablation.
36479Laser vein ablation
36479 reports laser ablation of an additional vein. Choose 36474 when the additional vein is treated with the mechanochemical method.
36483Vein ablation
36483 is for an additional vein treated with chemical adhesive. Code 36474 is for mechanochemical treatment.

36474 billing questions

When should 36474 be reported instead of 36473?

Use 36473 for the first vein treated with mechanochemical ablation. Report 36474 for each qualifying additional vein in the same extremity, treated through a separate access site.

Can 36474 be billed by itself?

No. It is an add-on code and must be reported with 36473 for the primary vein treatment.

What documentation supports the additional-vein service?

Document the mechanochemical method, the first and additional veins treated, the extremity, and the separate access site for the additional vein.

How is bilateral treatment handled?

CMS pays a bilateral procedure reported with modifier 50 at 150%. The add-on remains linked to the primary mechanochemical ablation service.

How does this differ from 36476?

36474 is for an additional vein treated by mechanochemical ablation. Code 36476 is the additional-vein code for radiofrequency ablation.

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.
