CPT 37236: Arterial Stent Placement, Endovascular

CPT code 37236 represents arterial stent placement performed via catheter-based techniques, including necessary radiologic imaging and any angioplasty within the same vessel. It covers percutaneous and open access approaches but explicitly excludes stent placement in lower extremity, cervical carotid, intracranial, and coronary arteries. This procedure is widely used in vascular and interventional specialties to restore or maintain arterial patency in non-coronary, non-intracranial, non-carotid beds.

Key national payers relevant to this code include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find practical context on the clinical scope of the code, typical settings where the service is delivered (hospital outpatient, inpatient operating room, and properly equipped ambulatory surgical centers), and the common billing considerations tied to stent placement procedures. The publication summarizes benchmark elements, coding boundaries (what is included and excluded), and clinical context necessary for accurate reporting and reimbursement. Data not available in the input are explicitly identified where applicable, and the piece avoids state-specific guidance, focusing instead on national applicability for clinicians, billing professionals, and policy analysts.

Billing Code Overview

CPT code 37236 describes the insertion of a stent in an artery using catheter-based techniques. The procedure includes any radiologic imaging necessary to complete the intervention and encompasses angioplasty performed within the same vessel when done by the provider. This code excludes stent placement in the lower extremity, cervical carotid, intracranial, and coronary arteries.

Service type: Endovascular arterial stent placement (percutaneous or open access)
Typical site of service: Hospital outpatient department or inpatient operating/interventional suite; may also be performed in ambulatory surgical centers equipped for endovascular interventions.

Clinical & Coding Specifications

Clinical Context

A 68-year-old patient with peripheral arterial disease (PAD) presents with lifestyle-limiting claudication of the right lower extremity and an angiographically significant focal stenosis of the right superficial femoral artery. After noninvasive testing (ankle-brachial index, arterial duplex) and diagnostic peripheral angiography confirming a hemodynamically significant lesion, the vascular interventionalist performs percutaneous transluminal stent placement. The procedure is performed in an outpatient ambulatory surgical center or hospital catheterization lab under conscious sedation with local arterial access (percutaneous common femoral approach). Intraprocedural digital subtraction angiography is used to visualize the lesion, guidewire and balloon angioplasty are performed when indicated, and a self-expanding or balloon-expandable stent is deployed in the target artery. Hemostasis is achieved using manual compression or a vascular closure device. The patient is monitored post-procedure in a recovery area and discharged the same day if stable, or admitted if complications occur. Documentation includes CPT code 37236, detailed procedure note of access, imaging performed, vessels treated, stent type and size, any adjunctive angioplasty, and immediate post-deployment angiographic result.
