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%.
