CPT® Code 37239

Add-On Code

Transcatheter placement of an intravascular stent(s), open or percutaneous, including radiological supervision and interpretation and including angioplasty within the same vessel, when performed; each additional vein (List separately in addition to code for primary procedure)

The CPT® Code 37239 refers to the transcatheter placement of an intravascular stent in a vein, which can be performed either through an open or percutaneous approach. This procedure includes the necessary radiological supervision and interpretation, as well as angioplasty within the same vessel if it is performed. The placement of venous stents is particularly common in the iliac vein, although they can be utilized in any vein. The procedure typically begins with the puncture of the femoral vein, followed by the insertion of an introducer sheath. A guidewire is then introduced and advanced to the site of the stenosis, allowing for the subsequent advancement of a catheter over the guidewire. Roadmapping venograms are obtained to visualize the anatomy and pathology. A balloon catheter is then used to dilate the lesion, after which the stent delivery catheter is advanced to the lesion site for stent deployment. Following the deployment, additional venograms are performed to assess the stent placement and the patency of the vein. This code is specifically used for each additional vein treated, following the initial vein treatment, which is coded separately. The procedure is crucial for restoring venous patency and improving blood flow in affected areas.
