What 37238 covers

Code 37238 reports placement of one or more stents in the initial vein treated, using an open or percutaneous approach. It is used for venous narrowing or obstruction, such as iliac or central venous disease. Interventional radiologists and vascular surgeons commonly perform the procedure in an angiography suite or operating room. The code includes radiological supervision and interpretation and angioplasty performed in the same vein; multiple stents placed in that vein do not make it an additional vein.

Report 37238 for the initial vein and use 37239 for each additional vein treated. The operative or procedure report should identify the treated vein, the stent placement, and any same-vein angioplasty. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Bilateral adjustment is not appropriate for this code. Assistant-at-surgery payment requires documentation of medical necessity; 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.

37238 billing questions

When should 37238 be chosen over 37236?

Use 37238 for stent placement in a vein and 37236 for stent placement in an artery. The vessel treated determines which code applies.

How are additional stents or veins reported?

Multiple stents in the initial vein are reported with 37238. Use add-on code 37239 for each additional vein treated.

Can angioplasty in the stented vein be reported separately?

Angioplasty performed in the same vein is included in 37238. The code also includes radiological supervision and interpretation.

What documentation supports 37238?

The procedure report should identify the vein treated and document stent placement. It should also describe any angioplasty performed in that same vein.

How does the 0-day global period affect same-day care?

Same-day preoperative and postoperative care is included in the procedure's 0-day global period.

When is assistant-at-surgery payment allowed?

CMS allows assistant-at-surgery payment only when the record documents medical necessity. 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.
