2025 CPT code 37237
(Active) Effective Date: N/A Revision Date: N/A Surgical Procedures on the Cardiovascular System - Endovascular Revascularization Surgery Feed
Placement of each additional intravascular stent in an artery (excluding lower extremity arteries) via catheter, open or percutaneous approach; includes angioplasty and radiological supervision/interpretation within the same vessel.This is an add-on code and requires a primary procedure code.
Modifiers may be applicable depending on the specific circumstances of the procedure, such as location of service, anesthesia provided, or assistant surgeon involvement. Consult the CPT manual and payer-specific guidelines for modifier application rules.
Medical necessity for stent placement is based on the presence of significant stenosis or occlusion in a targeted artery, leading to compromised blood flow and associated clinical symptoms such as angina, stroke, or claudication.Documentation must show that the stenosis or occlusion is causing significant hemodynamic compromise and that other conservative treatment options have failed or are not suitable.Payer-specific criteria for medical necessity should also be considered.
The physician's responsibility includes pre-procedural assessment, catheter insertion and advancement, contrast injection for imaging, angioplasty if needed, stent placement using radiological guidance, catheter removal, and hemostasis at the access site. Post-procedure monitoring and follow-up care may also be included in the physician's responsibilities, but the specific details would depend on the individual practice's protocols.
In simple words: This code describes placing an extra stent in an artery using a thin tube (catheter) after already placing a stent in another artery during the same visit.The doctor uses imaging to guide the placement and may also widen the artery before placing the stent. This is an additional charge and only used if a primary stent procedure (in a different artery) was also done.
This CPT code, 37237, represents the add-on procedure for the transcatheter placement of each additional intravascular stent(s).This applies to arteries excluding lower extremity arteries such as the cervical carotid, extracranial vertebral, intrathoracic carotid, intracranial, or coronary arteries. The procedure may be performed via an open or percutaneous approach. The code encompasses radiological supervision and interpretation, along with any angioplasty performed within the same vessel during the procedure.This code should only be reported in addition to the primary procedure code (37236) for the initial stent placement.It does not include separate reporting of radiological supervision and interpretation or angioplasty. This add-on code is not used in conjunction with codes 36836, 36837, 34841-34848 for bare metal or covered stents placed in visceral branches of endoprosthesis target zone, or with specific codes for lower extremity, carotid, intracranial, or coronary stents.
Example 1: A patient presents with stenosis in the right internal carotid artery and the left internal carotid artery.The physician performs a transcatheter stent placement in the right internal carotid artery (37236).An additional stent is then placed in the left internal carotid artery (37237). , A patient with coronary artery disease undergoes a percutaneous coronary intervention (PCI) with stent placement in the left anterior descending artery (92928).A second stent placement is needed in a separate coronary artery branch; code 37237 is not applicable as coronary artery stenting has its own specific codes., A patient presents with a stenosis in the right common carotid and the right internal carotid arteries. During the procedure, the physician performs transcatheter stent placement in both the common carotid artery and the internal carotid artery. In this case, 37237 would be used to represent the placement of the second stent, while the primary procedure code would reflect the first stent placement.
Comprehensive medical history, including relevant symptoms and risk factors; pre-procedure imaging (angiograms) demonstrating the need for intervention; procedural notes detailing the approach (open or percutaneous), catheterization details, angioplasty (if performed), stent deployment specifics, and post-procedure results.Consent form documentation is also required.
** Always verify code applicability with payer-specific guidelines before submitting claims.This code is an add-on code and should only be reported in conjunction with a primary procedure code (37236). This code does not include separate reporting for radiological supervision and interpretation or angioplasty performed during the same vascular procedure.
