Summary & Overview
HCPCS S1091: Temporary Non‑Coronary Stent with Delivery System
HCPCS Level II code S1091 represents a temporary, non-coronary stent provided with its delivery system (propel). This device-based code covers short-term stenting in non-coronary vascular or luminal sites and is relevant for procedural billing where a delivery system is included with the stent. Nationally, device codes like S1091 matter because they affect facility and device reimbursement, inventory tracking, and device-specific utilization reporting.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical purpose, typical sites of service, common modifiers, and payer considerations. The publication provides benchmarks and coverage patterns where available, summarizes relevant policy updates affecting device billing, and situates S1091 within clinical workflows for temporary, non-coronary stenting procedures. Where input data is missing, the text notes that specific fields were not provided.
Billing Code Overview
HCPCS Level II code S1091 describes a temporary non-coronary stent supplied with its delivery system (propel). The service consists of placement of a short-term stent in a non-coronary vascular or luminal location using the supplied delivery mechanism.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who presents with symptomatic benign airway or tracheal stenosis, or with a temporary need to maintain patency of a non-coronary vascular or luminal structure (for example, peripheral arterial or venous stenosis) pending definitive therapy. The patient commonly has progressive dyspnea, stridor, recurrent infections, or ischemic symptoms related to luminal narrowing. Evaluation includes history, physical exam, cross-sectional imaging (CT or CTA), and endoscopic assessment or angiography. The procedure using S1091 (temporary non-coronary stent with delivery system) is performed in an interventional suite, operating room, or endoscopy/bronchoscopy suite under monitored anesthesia care or general anesthesia. The workflow includes pre-procedure consent and imaging review, intraprocedural placement of the stent via endoscopic or percutaneous access using fluoroscopic guidance, confirmation of position and patency, and post-procedure monitoring for complications such as migration, bleeding, or infection. Post-procedure care involves chest radiograph or angiographic run to confirm placement, brief inpatient observation or same-day discharge based on clinical status, and scheduled follow-up for stent removal or exchange if temporary therapy is intended.
