Summary & Overview
CPT 93462: Left Ventricular Transventricular Catheter Access
CPT code 93462 denotes a specialized transventricular approach to access the left ventricle by puncturing the interventricular septum or via direct apical entry through the chest wall. The code captures invasive catheter-based access used when conventional left-heart entry is limited by prior valve surgery, prosthetic material, or challenging cardiac anatomy. Nationally, the code matters because it represents higher-complexity cardiac procedures that often occur in hospital-based catheterization laboratories or operating rooms and can affect resource utilization, coding accuracy, and payer authorization processes.
Key payers reviewed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when transventricular access is used, typical sites of service, and what documentation elements support correct coding. The publication also outlines the payers covered and common modifiers associated with hospital-based invasive cardiac procedures. This summary provides a concise reference for billing, coding, and revenue cycle teams, as well as clinical staff involved in planning and documenting complex left-heart catheterization procedures.

Billing Code Overview
CPT code 93462 describes transventricular catheterization of the left ventricle performed by puncturing the interventricular septum or by direct apical access through the chest wall. This procedure is used when standard left-heart access is difficult or impossible, for example in patients with prosthetic valves or complex anatomy.
-
Service type: Invasive cardiac catheterization procedure for left ventricular access
-
Typical site of service: Hospital inpatient or hospital outpatient procedural settings, including cardiac catheterization laboratories and operating rooms
Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old with a history of prior mitral valve replacement and symptomatic left-sided valvular disease who now requires invasive hemodynamic assessment and left ventricular angiography. The patient presents from the cardiology inpatient service for left ventricular catheterization via transthoracic or transseptal approach because standard retrograde arterial access to the left ventricle is contraindicated or technically impossible due to a prosthetic valve or severe peripheral arterial disease. The clinical workflow includes pre-procedure informed consent and review of anticoagulation, sedation or general anesthesia per anesthesiology, ultrasound-guided vascular access (if transseptal) or surgical exposure of the ventricular apex (if apical puncture), sterile field setup in a catheterization laboratory or hybrid operating room, direct left ventricular catheter placement, hemodynamic measurements and imaging (left ventriculography), documentation of findings, and post-procedure monitoring in a recovery or intensive care area with attention to bleeding and arrhythmia risk. Typical payors for authorization and claims processing include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
