What 37239 covers

Code 37239 represents stent placement in an additional vein during an open or percutaneous venous intervention. It may be used for venous obstruction or stenosis treated by specialists such as interventional radiologists or vascular surgeons, including in iliac or central veins. The code counts additional veins treated, not the number of stents placed in one vein. Balloon angioplasty performed in the same vein as the stent is included in the stent service.

Report 37239 with the primary code for the first treated vein, 37238. The operative or procedure report should identify the additional vein treated and document the stent placement; it should distinguish that vein from the first vein and any other treated sites. Under the CMS payment rule, this add-on code is billed only with a primary procedure and is paid within that procedure's global period.

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.

37239 billing questions

When is 37239 reported instead of 37238?

Use 37238 for the first vein treated with a stent. Report 37239 for each additional vein treated in the procedure.

Is 37239 counted per stent or per vein?

It is counted per additional vein treated, not per stent. Multiple stents placed in one vein do not make that vein an additional vein.

Can 37239 be billed by itself?

No. It is an add-on code and must be reported with a primary procedure, typically 37238 for the first venous stent.

Is angioplasty separately reported in the stented vein?

Angioplasty performed in the same vein as the stent is included in the stent service. The report should identify the vein in which the stent was placed.

What documentation supports reporting an additional unit?

Document each additional vein treated and the stent placement in that vein. The record should make clear which vein was treated first and which veins support add-on reporting.

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.
