Summary & Overview
CPT 0643T: Percutaneous Left Ventricular Restoration Procedure
CPT code 0643T represents a percutaneous, transarterial left ventricular restoration procedure in which a catheter is navigated through the arterial system to deploy a restoration device inside the heart’s left ventricle. This category III CPT code captures an image-guided structural cardiac intervention intended to restore or support left ventricular anatomy or function. Nationally, the code is relevant to hospitals, cardiovascular specialists, and payers managing coverage for advanced structural heart therapies.
Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context, expected sites of service, and common operational considerations for billing and claims processing. The publication summarizes available benchmarks, common modifier usage patterns, and payer coverage trends where available. It also outlines clinical indications and how the procedure fits into the broader landscape of percutaneous structural heart interventions.

Billing Code Overview
CPT code 0643T describes a catheter-based procedure in which a provider navigates a catheter through the arterial system to place a restoration device in the left ventricle of the heart. This is an image-guided, intravascular therapeutic intervention performed to restore or support left ventricular structure or function.

Clinical & Coding Specifications
Clinical Context
A 76-year-old male with ischemic cardiomyopathy and a chronically reduced left ventricular ejection fraction presents with progressive heart failure symptoms (NYHA class III) despite guideline-directed medical therapy. Coronary angiography excludes a revascularization target, and multi-disciplinary heart team evaluation determines the patient is a candidate for a transcatheter left ventricular restoration procedure. Under conscious sedation or general anesthesia in a cardiac catheterization laboratory or hybrid operating room, the interventional cardiology team gains arterial access (commonly femoral), advances a steerable catheter retrograde across the aortic valve into the left ventricle, and deploys the restoration device to reduce ventricular volume and reshape the ventricle. Intraprocedural transesophageal echocardiography and fluoroscopy guide placement. Postprocedure, the patient is transferred to an intensive care or step-down unit for hemodynamic monitoring and echocardiographic assessment, with discharge planning that includes heart failure medication optimization and cardiac rehabilitation.

80 | Assistant surgeon | Use when an assistant surgeon provided intraoperative assistance. |
81 | Minimum assistant surgeon | Use when minimal assistant surgeon services were provided. |
82 | Assistant surgeon (when qualified resident not available) | Use when an assistant surgeon is required but a qualified resident is not available. |
73 | Discontinued outpatient procedure before anesthesia administration | Use when the outpatient procedure is cancelled prior to administration of anesthesia. |
78 | Unplanned return to OR for a related procedure during the global period | Use for emergent reoperation related to the index procedure (repeat listed for emphasis when applicable). |
