Summary & Overview

CPT 0797T: Right Ventricular Leadless Pacemaker Implantation

CPT code 0797T covers catheter-based implantation of the right ventricular component of a dual–chamber leadless pacemaker system, a minimally invasive cardiac device procedure that expands options for patients needing ventricular pacing without traditional transvenous leads. Nationally, this code reflects growing adoption of leadless pacing technology and has implications for hospital cardiovascular service lines, electrophysiology programs, and device supply chains. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and procedure setting, payer coverage considerations, common modifiers used with the code, and the types of benchmarks and policy updates typically relevant for device implantation codes. The publication also summarizes expected site-of-service patterns, typical service line alignments, and areas where payers often focus prior authorization or coverage policy language. Data not available in the input for some payer-specific reimbursement benchmarks and ICD-10 mapping is noted where applicable.

Billing Code Overview

CPT code 0797T describes implantation of the right ventricular component of a dual–chamber leadless pacemaker system using a catheter-based approach. The procedure involves intravascular delivery and deployment of the right ventricular pacemaker component, and the provider may use imaging guidance during the implantation.

Service type: Leadless pacemaker implantation, right ventricular component, catheter-based cardiac procedure
Typical site of service: Hospital cardiac catheterization laboratory or specialized electrophysiology suite

Clinical & Coding Specifications

Clinical Context

A 76-year-old patient with symptomatic bradycardia and intermittent high-degree atrioventricular block is referred for implantation of the right ventricular component of a dual-chamber leadless pacemaker system. The patient has comorbidities that increase lead- and pocket-related complication risks (for example, prior device infection, limited venous access, or chronic immunosuppression). The interventional electrophysiology team performs the procedure in a cardiac catheterization laboratory or hybrid operating room under conscious sedation or monitored anesthesia care. Vascular access is obtained via the femoral vein, a delivery catheter is advanced to the right ventricle under fluoroscopic and/or intracardiac echocardiography guidance, and the leadless RV pacemaker component is deployed and tested for electrical parameters. Hemostasis is achieved at the access site and the patient is observed for rhythm stability and vascular complications prior to discharge or admission for overnight monitoring if indicated.

`53`	Discontinued procedure	Use when the procedure is started but discontinued due to extenuating circumstances.
`62`	Two surgeons	Use when two surgeons with different specialties operate together and both report services.
`66`	Surgical team	Use when a surgical team reports services per payer policy.
`78`	Unplanned return to OR for a related procedure by the same physician	Use when the patient returns to the operating room the same day or within the global period for a related complication.
`80`	Assistant surgeon	Use when an assistant surgeon assists at the primary procedure and payer allows billing.
`81`	Minimum assistant surgeon	Use when a minimum assistant surgeon service is provided and permitted by payer.
`82`	Assistant surgeon (when qualified resident unavailable)	Use when an assistant surgeon is required because a qualified resident is unavailable.
`AS`	Physician is the primary surgeon — ambulatory surgical center	Use to indicate the reporting physician is the surgeon in an ASC setting when required by payer.
`QK`	Medical direction of 2–4 CRNAs/AA by a physician	Use when the physician medically directs multiple anesthesia providers for the case.
`QX`	CRNA service with qualified physician absent	Use when a CRNA performs anesthesia services without a physician anesthesiologist present.
