Summary & Overview
HCPCS Level II C9792: Transcatheter Left Atrial to Coronary Sinus Shunt Implantation
HCPCS Level II code C9792 identifies a transcatheter left atrial to coronary sinus shunt implantation performed via jugular vein access for symptomatic NYHA class II, III, IVA heart failure in an IDE study setting. This emerging structural heart intervention is notable for its inclusion of intra-procedural mapping imaging (for example, TEE or ICE and fluoroscopy) and general anesthesia, reflecting complex catheter-based management of refractory heart failure.
The analysis covers national payer considerations including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context, coding scope, site-of-service implications, and typical documentation elements tied to this HCPCS Level II code. The publication highlights benchmarks and policy-relevant topics such as IDE study billing context, imaging-inclusive procedure coding, and anesthesia and facility implications for hospitals and hybrid labs.
Intended takeaways include clarity on what C9792 represents clinically and operationally, the types of payers that may encounter it, and the key areas administrators and coders should expect to address when this procedure appears in claims and registries.

Billing Code Overview
HCPCS Level II code C9792 describes a blinded or nonblinded procedure for symptomatic New York Heart Association (NYHA) class II, III, IVA heart failure: transcatheter implantation of a left atrial to coronary sinus shunt using jugular vein access. The description specifies inclusion of all imaging necessary to intra-procedurally map the coronary sinus for optimal shunt placement (for example, TEE or ICE ultrasound, fluoroscopy) and that the procedure is performed under general anesthesia in an approved investigational device exemption (IDE) study.
Service Type: Transcatheter structural heart intervention (left atrial to coronary sinus shunt implantation)
Typical Site of Service: Hospital operating/procedure room or hybrid catheterization laboratory under general anesthesia

Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with symptomatic chronic heart failure (NYHA Class III) despite guideline-directed medical therapy is enrolled in an approved investigational device exemption (IDE) study evaluating creation of a left atrial to coronary sinus shunt. The procedure is performed in a hybrid cardiac catheterization/surgical suite under general anesthesia via right internal jugular venous access. Intra-procedural imaging (transesophageal echocardiography — TEE or intracardiac echocardiography — ICE, and fluoroscopy) and coronary sinus mapping are used to identify optimal shunt location and confirm device positioning. The clinical workflow includes pre-procedure evaluation (heart failure assessment, anticoagulation review, informed consent for IDE participation), anesthesia induction, venous access and catheter navigation to the coronary sinus, shunt deployment between the left atrium and coronary sinus, intra-procedural imaging confirmation of flow and device stability, hemostasis, post-anesthesia recovery, and inpatient or monitored observation with post-procedural imaging and device surveillance per study protocol.
