What 36483 covers

This add-on describes catheter delivery of a medical adhesive to close an additional incompetent superficial vein in the same extremity. It is used after the primary vein has been treated with the adhesive-ablation technique. Vascular surgeons, interventional radiologists, and other qualified vein specialists commonly perform the procedure in an office or facility setting, using imaging to guide and monitor treatment.

Report 36483 with primary code 36482, not by itself. The additional vein must be in the same extremity and treated through a separate access site; documentation should identify the treated veins, access sites, laterality, and adhesive technique. Report each qualifying additional vein according to the code’s unit definition. CMS treats this as an add-on paid within the primary procedure’s global period. For bilateral procedures reported with modifier 50, CMS pays 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.

36483 billing questions

Can 36483 be reported by itself?

No. It is an add-on code reported with 36482 for the primary adhesive-ablation treatment.

When is 36483 appropriate instead of 36482?

Use 36482 for the primary vein treated with adhesive. Use 36483 for each qualifying additional vein in the same extremity treated through a separate access site.

How many units should be reported?

Report a unit for each qualifying additional vein treated, as supported by the operative documentation and separate access site.

Does the code include imaging guidance?

The adhesive-ablation service includes imaging guidance and monitoring; do not separately report those elements as though they were outside the procedure.

How is bilateral treatment handled?

CMS identifies this as a bilateral procedure. When reported with modifier 50, CMS pays 150%.

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.
