The CPT® Code 37237 refers to the transcatheter placement of an intravascular stent in any artery except for those located in the lower extremities, cervical carotid, extracranial vertebral, intrathoracic carotid, intracranial, or coronary regions. This procedure can be performed using either an open or percutaneous approach. In the percutaneous method, access is typically gained through the femoral artery or another suitable access artery, where a puncture is made, and an introducer sheath is inserted to facilitate the procedure. Conversely, the open approach involves a small incision in the skin to expose the artery, allowing for the introducer sheath to be placed directly into the vessel. This method is particularly advantageous in cases of severe arteriosclerotic disease affecting the femoral or iliac arteries, where access may be more challenging. During the procedure, a guide wire is introduced and navigated to the site of the stenosis, followed by the advancement of a catheter over the guide wire. Roadmapping angiograms are performed to visualize the anatomy and the stenotic area. A stiff wire is then advanced to the stenosis, and a long guiding sheath is placed over the catheter and stiff wire, which are subsequently removed, leaving the guiding sheath in place. Angioplasty may be conducted prior to stent placement, where a balloon catheter is inflated at the lesion site to dilate the narrowed area. After the balloon is deflated and removed, the stent delivery catheter is advanced to the lesion, where the stent is positioned and deployed. Following deployment, a balloon catheter may be used again to ensure the stent is properly seated. Additional angiograms are obtained to assess the placement and patency of the artery. Finally, all catheters are removed, and pressure is applied to the vascular access site to prevent bleeding. This code also encompasses all necessary radiological supervision and interpretation associated with the procedure.

The transcatheter placement of an intravascular stent (CPT® Code 37237) is indicated for patients presenting with significant arterial stenosis in vessels other than the coronary arteries, cervical carotid arteries, extracranial vertebral arteries, intrathoracic carotid arteries, intracranial arteries, or lower extremity arteries. The procedure is typically performed in cases where there is a need to restore adequate blood flow due to conditions such as severe arteriosclerotic disease, which may lead to ischemia or other complications if left untreated.
The procedure for transcatheter placement of an intravascular stent involves several critical steps to ensure successful intervention. Initially, access to the vascular system is obtained through a percutaneous approach, typically via the femoral artery, where a puncture is made, and an introducer sheath is inserted. In cases where an open approach is warranted, a small incision is made to expose the artery, allowing for direct placement of the introducer sheath. This approach is particularly beneficial in patients with severe arteriosclerotic disease affecting the femoral or iliac arteries, where access may be more challenging.
After the transcatheter placement of an intravascular stent, patients are typically monitored for any complications, such as bleeding or vascular access site issues. The recovery process may involve observation in a healthcare setting to ensure stability and proper healing. Patients may be advised on activity restrictions and follow-up appointments to assess the effectiveness of the stent and monitor for any potential complications. It is essential to provide appropriate post-procedure care, including managing any discomfort and ensuring that the patient understands the signs of complications that may require immediate medical attention.
